NEW ENGLAND REALTY ASSOCIATES LIMITED PARTNERSHIP

PART I

ITEM 1. BUSINESS

General

New England Realty Associates Limited Partnership (“NERA” or the “Partnership”), a Massachusetts Limited Partnership, was formed on August 12, 1977 as the successor to five real estate limited partnerships (collectively, the “Colonial Partnerships”), which filed for protection under Chapter XII of the Federal Bankruptcy Act in September 1974. The bankruptcy proceedings were terminated in late 1984. In July 2004, the General Partner extended the termination date of the Partnership until 2057.

The authorized capital of the Partnership is represented by three classes of partnership units (“Units”). There are two categories of limited partnership interests (“Class A Units” and “Class B Units”) and one category of general partnership interests (the “General Partnership Units”). The Class A Units were initially issued to creditors and limited partners of the Colonial Partnerships and have been registered under Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Each Class A Unit is exchangeable for 30 publicly traded Depositary Receipts (“Depositary Receipts”), which are currently listed on the NYSE American and are registered under Section 12(b) of the Exchange Act. The Class B Units were issued to the original general partners of the Partnership. The General Partnership Units are held by the current general partner of the Partnership, NewReal, Inc. (the “General Partner” or “NewReal”). The Class A Units represent an 80% ownership interest, the Class B Units represent a 19% ownership interest, and the General Partnership Units represent a 1% ownership interest.

The Partnership is engaged in the business of acquiring, developing, holding for investment, operating and selling real estate. The Partnership, directly or through 31 subsidiary limited partnerships or limited liability companies, owns and operates various residential apartments, condominium units and commercial properties located in Massachusetts and New Hampshire. As used herein, the Partnership’s subsidiary limited partnerships and limited liabilities companies are each referred to as a “Subsidiary Partnership” and are collectively referred to as the “Subsidiary Partnerships.”

The Partnership owns between a 99.67% and 100% interest in each of the Subsidiary Partnerships, except in seven limited liability companies (collectively, the “Investment Properties” or “Joint Ventures”) in which the Partnership has between a 40% and 50% ownership interest. Jameson Brown and Harley Brown indirectly collectively own between 47.6% and 59%, and five other current and past employees of Hamilton own collectively between 0% and 2.4%, respectively of the Joint Ventures. The Partnership’s interest in the Investment Properties is accounted for on the equity method in the Consolidated Financial Statements. See Note 1 to the Consolidated Financial Statements—“Principles of Consolidation.” See Note 15 to the Consolidated Financial Statements—“Investment in Unconsolidated Joint Ventures” for a description of the properties and their operations. Of those Subsidiary Partnerships not wholly owned by the Partnership, except for the Investment Properties, the remaining ownership interest is held by an unaffiliated third party. In each such case, the third party has entered into an agreement with the Partnership, pursuant to which any benefit derived from the third party’s ownership interest in the applicable Subsidiary Partnerships will be returned to the Partnership.

The long-term goals of the Partnership are to manage, rent and improve its properties and to acquire additional properties with income and capital appreciation potential as suitable opportunities arise. When appropriate, the Partnership may sell or refinance selected properties. Proceeds from any such sales or refinancing will be used to reduce debt, reinvest in acquisitions of other properties, make distributions to the partners, repurchase equity interests, or use for operating expenses or reserves, as determined by the General Partner.

Operations of the Partnership

As of December 31, 2023, Sally Michael and David Reier, the Trustees of the estate of Harold Brown, held voting control over the capital stock of NewReal, the General Partner of the Partnership. The estate was closed on January 2, 2024, whereupon the capital stock of NewReal previously owned by the estate of Harold Brown were transferred to JPB Real Estate LLC and Maisie Brown LLC, entities controlled by Jameson Brown and Harley Brown respectively, with each entity acquiring 37.5% of the voting control of NewReal at that time.

The General Partner has engaged The Hamilton Company, Inc. (the “Hamilton Company” or “Hamilton”) to perform general management functions for the Partnership’s properties in exchange for management fees. The Hamilton Company is wholly owned by JPB Real Estate LLC and Maisie Brown LLC. The Partnership, the Subsidiary Partnerships, and the Investment Properties currently contract with the Hamilton Company for 58 individuals at the Properties (as defined below) and 11 individuals at the Joint Ventures who are primarily involved in the supervision and maintenance of specific properties. The General Partner has no employees.

As of February 1, 2025, the Partnership and its Subsidiary Partnerships owned 2,943 residential apartment units in 27 residential and mixed-use complexes (collectively, the “Apartment Complexes”). The Partnership also owns 19 condominium units in a residential condominium complex, all of which are leased to residential tenants (collectively, the “Condominium Units”). The Apartment Complexes, the Condominium Units and the Investment Properties are located primarily in the metropolitan Boston area of Massachusetts.

As of February 1, 2025, the Subsidiary Partnerships also owned two commercial shopping centers in Framingham, Massachusetts, one commercial building in Newton, Massachusetts, one commercial building in Brookline, Massachusetts and commercial space in mixed-use buildings in Boston, Brockton and Newton, Massachusetts, totaling approximately 131,000 square feet of commercial space. These properties are referred to collectively as the “Commercial Properties.” See Note 2 to the Consolidated Financial Statements for more information.

Additionally, as of February 1, 2025, the Partnership owned a 40-50% interest in 7 residential and mixed use complexes, the Investment Properties, with a total of 688 residential units, one commercial unit, and a 50 car parking lot. See Note 15 to the Consolidated Financial Statements for additional information on these investments.

The Apartment Complexes, Investment Properties, Condominium Units and Commercial Properties are referred to collectively as the “Properties.”

The Brown family entities, including JPB Real Estate LLC and Maisie Brown LLC, entities controlled by Jameson Brown and Harley Brown respectively, and, in certain cases, Ronald Brown, and officers, employees and former employees of The Hamilton Company own or have owned interests in certain of the Properties, Subsidiary Partnerships and Joint Ventures. See “Item 13. Certain Relationships, Related Transactions and Director Independence.”

The leasing of real estate in the metropolitan Boston area of Massachusetts is highly competitive. The Apartment Complexes, Condominium Units and the Investment Properties must compete for tenants with other residential apartments and condominium units in the areas in which they are located. The Commercial Properties must compete for commercial tenants with other shopping malls and office buildings in the areas in which they are located. Thus, the level of competition at each Property depends on how many other similarly situated properties are in its vicinity. In addition to Item 1A, Risk Factors, see “Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors that May Affect Future Results.”

Table of Contents

The Second Amended and Restated Contract of Limited Partnership of the Partnership (the “Partnership Agreement”) authorizes the General Partner to acquire real estate and real estate related investments from or in participation with either or both of the Brown family related entities and Ronald Brown, or their affiliates, upon the satisfaction of certain terms and conditions, including the approval of the Partnership’s Advisory Committee and limitations on the price paid by the Partnership for such investments. The Partnership Agreement also permits the Partnership’s limited partners and the General Partner to make loans to the Partnership, subject to certain limitations on the rate of interest that may be charged to the Partnership. Except for the foregoing, the Partnership does not have any policies prohibiting any limited partner, General Partner or any other person from having any direct or indirect pecuniary interest in any investment to be acquired or disposed of by the Partnership or in any transaction to which the Partnership is a party or has an interest in or from engaging, for their own account, in business activities of the types conducted or to be conducted by the Partnership. The General Partner is not limited in the number or amount of mortgages which may be placed on any Property, nor is there a policy limiting the percentage of Partnership assets which may be invested in any specific Property.

Unit Distributions

In March 2025, the Partnership approved a quarterly distribution of $12.00 per Unit ($0.40 per Receipt), payable on March 31, 2025. In addition to the quarterly distribution, there will be a special distribution of $96.00 per Class A unit ($3.20 per Receipt). In 2024 the Partnership paid an aggregate distribution of $48.00 per Unit ($1.60 per Receipt) for a total payment of $11,244,559 in 2024. In 2023, the Partnership paid a total distribution of an aggregate $84.00 Unit ($2.80 per Receipt), for a total payment of $9,954,888.

On August 20, 2007, NewReal, Inc., the General Partner authorized an equity repurchase program (the “Repurchase Program”) under which the Partnership was permitted to purchase, over a period of twelve months, up to 300,000 Depositary Receipts (each of which is one-tenth of a Class A Unit). Over time, the General Partner has authorized increases in the equity repurchase program. On March 10, 2015, the General Partner authorized an increase in the Repurchase Program to 2,000,000 Depository Receipts and extended the Program for an additional five years from March 31, 2015 until March 31, 2020. On March 9, 2020, the General Partner extended the program for an additional five years, from March 31,2020, until March 31, 2025.

On March 12, 2025, the General Partner authorized the President and Treasurer to cause the Partnership to repurchase, on the open market or otherwise, including through individually negotiated purchases and through a written trading plan that complies with the requirements of Rule 10b5-1, Depositary Receipts and Partnership Units such that (i) the aggregate cost of Depositary Receipts and Partnership Units repurchased shall not exceed the lesser of $5 million or 10% of the Partnership’s balance of cash and investment in treasury bills, (ii) no Depositary Receipts or Partnership Units shall be repurchased after the date that is 12 months after the effective date of the plan, and (iii) no Depositary Receipts or Partnership Units shall be repurchased in excess of $95 per Depository Receipt ( the “Repurchase Plan”). The Repurchase Plan requires the Partnership to repurchase a proportionate number of Class B Units and General Partner Units in connection with any repurchases of any Depositary Receipts by the Partnership based upon the 80%, 19% and 1% fixed distribution percentages of the holders of the Class A, Class B and General Partner Units under the Partnership Agreement. This repurchase authorization replaces the Partnership’s previous repurchase program. The Repurchase Plan shall be made in accordance with the terms of Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and shall be made in accordance with all applicable laws and regulations in effect from time to time.

From August 20, 2007 through December 31, 2024, the Partnership has repurchased 1,550,358 Depositary Receipts at an average price of $31.82 per receipt (or $954.60 per underlying Class A Unit), 4,537 Class B Units and 239 General Partnership Units, both at an average price of $1,289.00 per Unit, totaling approximately $56,090,000, inclusive of brokerage fees paid by the Partnership.

Property Transactions

On November 30, 2021, the Partnership entered into a Master Credit Facility Agreement (the “Facility Agreement”) with KeyBank National Association (“KeyBank”), dated as of November 30, 2021, with an initial advance

Table of Contents

in the amount of $156,000,000. Interest only on the debt at a fixed interest rate of 2.97% is payable on a monthly basis through December 31, 2031. The Partnership’s obligations under the Facility Agreement are secured by mortgages on certain properties pursuant to certain Mortgage, Assignment of Leases and Rents, and Security Agreement and Fixture Filings (“Mortgages”).

The Partnership used the proceeds from the Facility Amendment to pay down approximately $65,300,000 of existing debt secured by 11 properties, along with approximately $2,700,000 in prepayment penalties. The remaining balance of approximately $89,000,000 was used for general partnership purposes.

On June 16, 2022, the Partnership entered into an amendment to the Facility Agreement (the “Facility Amendment”). The Facility Amendment included an additional advance in the amount of $80,284,000 at a fixed interest rate of 4.33%.

The Partnership used the proceeds to pay down approximately $37,065,000 of existing debt secured by four properties, along with approximately $854,000 in prepayment penalties. The remaining balance of approximately $42,384,000 will be used for general partnership purposes.

On October 14, 2022, the Partnership entered into a loan agreement with Brookline Bank (the “Brookline Agreement”), which refinanced its loan on 659-665 Worcester Road, Framingham, MA. The Brookline Agreement pays down the loan on the existing debt of $5,954,546, extends the maturity until October 14, 2032, at a variable interest rate of SOFR rate, plus 1.7% interest only for two years and amortizing using a thirty-year schedule for the balance of the term. At closing, the Partnership entered into an interest rate swap contract with Brookline Bank with a notional amount equivalent to the underlying loan principal amortization, resulting in a fixed rate of 4.60% through the expiration of the interest rate swap contract. The agreement also allows for an earn out of up to an additional $1,495,453 once the property performance reaches a 1.35x debt service coverage ratio and the loan to value equates to at most 65%.

The Partnership purchased a commercial retail property of approximately 20,700 square feet, located at 653 Worcester Road in Framingham, MA for the sum of approximately $10,151,000 on January 18, 2023. This acquisition was funded from the Partnership’s cash reserves and closing costs were approximately $59,000. From the purchase price, the Partnership allocated approximately $585,000 for in-place leases, and approximately $378,000 to the value of tenant relationships. These amounts are being amortized over 12 and 156 months respectively.

On July 14, 2023, the Partnership purchased a 52 unit mixed use property in the South End neighborhood of Boston, MA comprised of three buildings at 26-30 Rutland Street, 105-117 West Concord Street and 475 Shawmut Avenue, and approximately 3,400 square feet of commercial space for a purchase price of approximately $27,500,000. This acquisition was funded from the Partnership’s cash reserves and closing costs were approximately $81,000. From the purchase price, the Partnership allocated approximately $525,000 for in-place leases, approximately $61,000 to the value of tenant relationships and $241,000 to the value of below-market leases. These amounts are being amortized over 12 and 36 months respectively.

Table of Contents

During 2024, the Partnership and its Subsidiary Partnerships completed improvements to certain of the Properties at a total cost of approximately $25,254,000, which includes approximately $15,231,000 for the Mill Street Development. These improvements were funded from cash reserves and, to some extent, escrow accounts established in connection with the financing or refinancing of the applicable Properties. These sources have been adequate to fully fund improvements. The most significant improvements were made at Executive Apartments,1144 Commonwealth, Captain Parker, River Drive Apartments, Redwood Hills, and Hamilton Oaks, at a cost of $1,582,000, $1,061,000, $886,000, $880,000, $872,000, and $782,000, respectively. The Partnership plans to invest approximately $30,837,000 in capital improvements for all properties in 2025. This amount includes approximately $14,769,000 toward the development of a 72 unit apartment complex at Mill Street Development.

As of December 31, 2024, the Partnership has one property under construction located at 57 Mill Street in Woburn, MA. The project includes 72 residential units comprising approximately 93,000 square feet and is estimated to be completed during the fourth quarter of 2025. Total investment to date is approximately $15.2 million, and the total investment upon completion is anticipated to be approximately $30 million. The partnership is using cash reserves to fund this construction but will finance a portion of construction costs upon completion of the project. In connection with the Mill Street development project, the Partnership has entered into a contract with a general contractor with a current contract value of approximately $30 million.

Line of Credit

On November 21, 2024, the Partnership entered into an agreement for a new $25,000,000 revolving line of credit. The term of the line is for three years with a floating interest rate equal to a base rate of the SOFR Rate for a period of one month plus the applicable margin of 2.5%. The loan covenants include a leverage ratio not to exceed 65%, a debt service coverage ratio of not less than 1.5 to 1.0, maximum usage of 1.5 times trailing 12 months EBITDA, minimum liquidity of $15 million, and a debt yield of at least 8.5%. The Partnership incurred a commitment fee of $125,000. The Partnership will be charged annually an unused line fee, equal to seventy-five basis points (0.75%) between the difference of the maximum availability and the outstanding principal of the line of credit. This fee will be waived for any period in which the Partnership maintains aggregate deposits of $20,000,000 with the Lender. As of December 31, 2024, the Partnership was in compliance with the financial covenants and did not incur an unused line fee.

The line of credit may be used for acquisitions, refinancing, improvements, working capital and other needs of the Partnership. The line may not be used to pay dividends, make distributions or acquire equity interests of the Partnership.

The line of credit is collateralized by varying percentages of the Partnership’s ownership interest in 27 of its Subsidiary Partnerships and Joint Ventures. Pledged interests are 49% of the Partnership’s ownership interest in the respective entities.

Advisory Committee

As of December 31, 2024, the Advisory Committee members were Robert Nahigian and David Ross, limited partners of the Partnership. These Advisory Committee members are not affiliated with the General Partner. The Advisory Committee meets with the General Partner to review the progress of the Partnership, assist the General Partner with policy formation, review the appropriateness, timing and amount of proposed distributions, approve or reject proposed acquisitions and investments with affiliates, and advise the General Partner on various other Partnership affairs. Per the Partnership Agreement, the Advisory Committee has no binding power except that it must approve certain investments and acquisitions or sales by the Partnership from or with affiliates of the Partnership.

ITEM 1A. RISK FACTORS

We are subject to certain risks and uncertainties as described below. These risks and uncertainties may not be the only ones we face; there may be additional risks that we do not presently know of or that we currently consider immaterial. All of these risks could adversely affect our business, financial condition, results of operations and cash flows. Our ability to pay distributions on, and the market price of, our equity securities may be adversely affected if any of such risks are realized. All investors should consider the following risk factors before deciding to purchase or sell securities of the Partnership.

Table of Contents

We are subject to risks inherent in the ownership of real estate. We own and manage multifamily apartment complexes and commercial properties that are subject to varying degrees of risk generally incident to the ownership of real estate. Our financial condition, the value of our properties and our ability to make distributions to our shareholders will be dependent upon our ability to operate our properties in a manner sufficient to generate income in excess of operating expenses and debt service charges, which may be affected by the following risks, some of which are discussed in more detail below:

● a lessening of demand for the multifamily and commercial units that we own;

● development by competitors of competing multi-family communities;

● increases in property and liability insurance costs;

● weather and other conditions that might adversely affect operating expenses;

● our inability to control operating expenses or achieve increases in revenues;

● the results of litigation filed or to be filed against us;

● risks related to our joint ventures;

● catastrophic property damage losses that are not covered by our insurance;

Table of Contents

We are dependent on rental income from our multifamily apartment complexes and commercial properties. If we are unable to attract and retain tenants or if our tenants are unable to pay their rental obligations, our financial condition and funds available for distribution to our shareholders will be adversely affected.

Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer. Although we employ a number of measures to prevent, detect and mitigate cybersecurity attacks, our business is at risk from and may be impacted by such attacks as there is no guarantee such efforts will be successful in preventing a cyber-attack. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks, and there can be no assurance that our actions, security measures, and controls designed to prevent, detect, or respond to intrusion; to limit access to data; to prevent loss, destruction, alteration, or exfiltration of business information; or to limit the negative impact from such attacks can provide absolute security against a cybersecurity incident. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, disruption to our operations, increased cybersecurity insurance premiums and damage our reputation, which could adversely affect our business. Our Audit Committee is responsible for overseeing our cybersecurity and data privacy risks. Our cybersecurity program is led by the Hamilton Company’s Chief Financial Officer, who, along with the Hamilton Company’s Director of Information Technology, provide regular updates each quarter to the Audit Committee regarding this program, including information about the cybersecurity threat landscape, investments in infrastructure and opportunities to protect and enhance the Company’s systems and security of products and operations. In addition, the Board of Directors of the General Partner (the “Board” or “Board of Directors”) receives periodic briefings from management regarding cybersecurity activities and initiatives.

Our multifamily apartment complexes and commercial properties are subject to competition. Our properties and joint venture investments are located in developed areas that include other properties. The properties also compete with other rental alternatives, such as condominiums, single and multifamily rental homes, owner occupied single and multifamily homes, and commercial properties in attracting tenants. This competition may affect our ability to attract and retain residents and to increase or maintain rental rates.

The properties we own are concentrated in Eastern Massachusetts and Southern New Hampshire. Our performance, therefore, is linked to economic conditions and the market for available rental housing and commercial space in these states. A decline in the market for apartment housing and/or commercial properties may adversely affect our financial condition, results of operations and ability to make distributions to our shareholders.

Our insurance may not be adequate to cover certain risks. There are certain types of risks, generally of a catastrophic nature, such as earthquakes, floods, windstorms, act of war and terrorist attacks that may be uninsurable, or are not economically insurable, or are not fully covered by insurance. Moreover, certain risks, such as mold and environmental exposures, generally are not covered by our insurance. Should an uninsured loss or a loss in excess of insured limits occur, we could lose our equity in the affected property as well as the anticipated future cash flow from that property. Any such loss could have a material adverse effect on our business, financial condition and results of operations.

Debt financing could adversely affect our performance. The vast majority of our assets are encumbered by project specific, non-recourse, non-cross-collateralized mortgage debt. There is a risk that these properties will not have sufficient cash flow from operations for payments of required principal and interest. We may not be able to refinance these loans at an amount equal to the loan balance and the terms of any refinancing may not be as favorable as the terms of existing indebtedness. If we are unable to make required payments on indebtedness that is secured by a mortgage, the Partnership will either pay down the underlying debt on the property or the property securing the mortgage may be foreclosed with a consequent loss of income and value to us.

We are obligated to comply with financial covenants in our indebtedness that could restrict our range of operating activities. The mortgages on our properties contain customary negative covenants, including limitations on our ability, without prior consent of the lender and other items. Failure to comply with these covenants could cause a default under the agreements and, in certain circumstances; our lenders may be entitled to accelerate our debt

obligations. Defaults under our debt agreements could materially and adversely affect our financial condition and results of operations.

Real estate investments are generally illiquid, and we may not be able to sell our properties when it is economically or strategically advantageous to do so. Real estate investments generally cannot be sold quickly, and our ability to sell properties may be affected by market conditions. We may not be able to diversify or vary our portfolio promptly in accordance with our strategies or in response to economic or other conditions.

Our access to public debt markets is limited. Substantially all of our debt financings are secured by mortgages on our properties because of our limited access to public debt markets.

Litigation may result in unfavorable outcomes. Like many real estate operators, we may be involved in lawsuits involving premises liability claims, housing discrimination claims and alleged violations of landlord-tenant laws, which may give rise to class action litigation or governmental investigations. Any material litigation not covered by insurance, such as a class action, could result in substantial costs being incurred.

Our financial results may be adversely impacted if we are unable to sell properties and employ the proceeds in accordance with our strategic plan. Our ability to pay down debt, reduce our interest costs, repurchase Depositary Receipts and acquire properties is dependent upon our ability to sell the properties we have selected for disposition at the prices and within the deadlines we have established for each respective property.

The costs of complying with laws and regulations could adversely affect our cash flow and ability to make distributions to our shareholders. Our properties must comply with Title III of the Americans with Disabilities Act (the “ADA”) to the extent that they are “public accommodations” or “commercial facilities” as defined in the ADA. The ADA does not consider apartment complexes to be public accommodations or commercial facilities, except for portions of such properties that are open to the public. In addition, the Fair Housing Amendments Act of 1988 (the “FHAA”) requires apartment complexes first occupied after March 13, 1990, to be accessible to the handicapped. Other laws also require apartment communities to be handicap accessible. Noncompliance with these laws could result in the imposition of fines or an award of damages to private litigants. We may be subject to lawsuits alleging violations of handicap design laws in connection with certain of our developments. If compliance with these laws involves substantial expenditures or must be made on an accelerated basis, our ability to make distributions to our shareholders could be adversely affected.

Under various federal, state and local laws, an owner or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances on, under or in the property. This liability may be imposed without regard to whether the owner or operator knew of, or was responsible for, the presence of the substances. Other laws impose on owners and operators certain requirements regarding conditions and activities that may affect human health or the environment. Failure to comply with applicable requirements could complicate our ability to lease or sell an affected property and could subject us to monetary penalties, costs required to achieve compliance and potential liability to third parties. We are not aware of any material noncompliance, liability or claim relating to hazardous or toxic substances or other environmental matters in connection with any of our properties. Nonetheless, it is possible that material environmental contamination or conditions exist, or could arise in the future, in the apartment communities or on the land upon which they are located.

We are subject to the risks associated with investments through joint ventures. Seven of our properties are owned by joint ventures in which we do not have a direct controlling interest. We may enter into joint ventures, including joint ventures that we do not control, in the future. Any joint venture investment involves risks such as the possibility that the co-venturer may seek relief under federal or state insolvency laws or have economic or business interests or goals that are inconsistent with our business interests or goals. While the bankruptcy or insolvency of our co-venturer generally should not disrupt the operations of the joint venture, we could be forced to purchase the co-venturer’s interest in the joint venture or the interest could be sold to a third party. We also may guarantee the indebtedness of our joint ventures. If we do not have control over a joint venture, the value of our investment may be affected adversely by a third party that may have different goals and capabilities than ours.

We are subject to risks associated with development, acquisition and expansion of multifamily apartment complexes and commercial properties. Development projects and acquisitions and expansions of apartment complexes are subject to a number of risks, including:

● availability of acceptable financing;

● competition with other entities for investment opportunities;

● failure by our properties to achieve anticipated operating results;

● construction costs of a property exceeding original estimates;

● delays in construction; and

We are subject to control by our directors and officers. The directors and executive officers of the General Partner and members of their families and related entities owned approximately 35% of our Depositary Receipts as of December 31, 2024. Additionally, management decisions rest with our General Partner without limited partner approval.

Competition for skilled personnel could increase our labor costs. We and our management company compete with various other companies in attracting and retaining qualified and skilled personnel who are responsible for the day- to-day operations of our properties. Competitive pressures may require that we enhance our pay and benefits package to compete effectively for such personnel. We may not be able to offset such added costs by increasing the rates we charge our tenants. If there is an increase in these costs or if we fail to attract and retain qualified and skilled personnel, our business and operating results could be harmed.

We depend on our key personnel. Our success depends to a significant degree upon the continued contribution of key members of the management company, who may be difficult to replace. The loss of services of these executives could have a material adverse effect on us. There can be no assurance that the services of such personnel will continue to be available to us. We do not hold key-man life insurance on any of our key personnel.

Changes in market conditions could adversely affect the market price of our Depositary Receipts. As with other publicly traded equity securities, the value of our Depositary Receipts depends on various market conditions, which may change from time to time. Among the market conditions that may affect the value of our Depositary Receipts are the following:

● the extent of investor interest in us;

● our financial performance; and

● general stock and bond market conditions.

The market value of our Depositary Receipts is based primarily upon the market’s perception of our growth potential and our current and potential future earnings and cash distributions. Consequently, our Depositary Receipts may trade at prices that are higher or lower than our net asset value per Depositary Receipt.

We face possible risks associated with the physical effects of climate change. We cannot predict with certainty whether climate change is occurring and, if so at what rate. However, the physical effects of climate change could have a material effect on our properties, operations, and business. To the extent climate change causes changes in

12

Table of Contents

weather patterns, our markets could experience increases in storm intensity and rising sea levels. Over time, these conditions could result in declining demand for our buildings or the inability of us to operate the buildings at all. Climate change may also have indirect effects on our business by increasing the cost of (or making unavailable) property insurance on terms we find acceptable, increasing the cost of energy and increasing the cost of snow removal at our properties. Proposed federal legislation to address climate change could increase utility and other costs of operating our properties which, if not offset by rising rental income, would reduce our net income. There can be no assurance that climate change will not have a material adverse effect on our properties, operations or business.

Risk of changes in the tax law applicable to real estate partnerships. Since the Internal Revenue Service, the United States Treasury Department and Congress frequently review federal income legislation, we cannot predict whether, when or to what extent new federal tax laws, regulations, interpretations or rulings will be adopted. Any such legislative action may prospectively or retroactively modify our tax treatment and therefore, may adversely affect taxation to us, and/or our partners.

If the IRS makes audit adjustments to our income tax returns, it may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from the Partnership. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties and interest, our cash available for distribution to our partners might be substantially reduced.

Some of our costs, such as operating and general and administrative expenses, interest expense, and real estate acquisition and construction costs, are subject to inflation. A portion of our operating expenses is sensitive to inflation. These include expenses for property-related contracted services such as janitorial and engineering services, utilities, repairs and maintenance, and insurance. Property taxes are also impacted by inflationary changes as taxes are regularly reassessed based on changes in the fair value of our properties. Additionally, inflationary pricing may have a negative effect on real estate acquisitions and the construction costs necessary to complete our renovation, development and redevelopment projects, including, but not limited to, costs of construction materials, labor, and services from third-party contractors and suppliers. Our commercial leases have fixed rent increases which may not increase in line with inflation, thus causing our net operating income to decrease. As a result, our financial condition, results of operations, and cash flows, as well as our ability to pay dividends, could be adversely affected over time.

Recent City of Boston regulations impose new energy performance standards and fines that may increase utilities and administrative costs in order to comply with disclosure and energy reduction requirements. The City of Boston has implemented a Building Emissions Reduction and Disclosure Ordinance that sets specific requirements for large buildings to reduce energy use with the goal of targeting zero emissions for large buildings by 2050. The ordinance restricts emissions standards to certain units that begin phasing in during 2025 with such limits decreasing over time according to specific thresholds based upon building use type. Non-compliance with either disclosure requirements or emission limits may result in the imposition of penalties for such time as non-compliance remains in effect. As a result, our financial condition, results of operations, and cash flows, as well as our ability to pay dividends, could be adversely affected over time.

Development project costs that exceed estimates. We may incur construction costs at the Mill Street development project that exceed our original estimates or experience competition delays due to increased material, labor, or other costs, or supply chain disruptions that could reduce the project’s profitability.

ITEM 1C. CYBERSECURITY

The Partnership’s information technology, communication networks, system applications, accounting and financial reporting platforms and related systems, and those that are offered to residents and tenants, are integral to the operation of the business. The Partnership utilizes these systems, among others, for financial analysis, management, and

13

Table of Contents

reporting, for facilitation of operations, including for the initiation, generation, and completion of resident leasing, for internal communications, and for various other aspects of the business.

The Partnership’s cybersecurity strategy is focused on detection, protection, incident response, security risk management and mitigation, and resiliency of the cybersecurity infrastructure. The Partnership has implemented or is inthe process of continuously evaluating, testing and updating various information security processes and policies designed to identify, assess and manage material risks from cybersecurity threats to the Partnership’s critical computer networks, third-party hosted services, communications systems, hardware and software, and critical data, including confidential information that is proprietary, strategic or competitive in nature, as well as any personally identifiable information related to the Partnership’s residents’ and employees’ personal data.

To operate its business, the Partnership engages certain third-party vendors to perform a variety of functions. The Partnership seeks to engage reliable, reputable service providers. Depending upon the nature of the services and the sensitivity of the data that a third-party service provider processes, the Partnership’s vendor management procedures include reviewing the cybersecurity procedures, imposing contractual requirements, and conducting as needed periodic reassessments. The Partnership seeks to further enhance this review to expand the scope and depth of this analysis.

Cybersecurity is a critical component of our risk management process. We recognize that no single technology, process, or business control can effectively prevent or mitigate all risks, thus we use a variety of tools including multi-factor authentication and antivirus and firewall protection, to help identify, protect, detect, respond to, and recover from cyber threats. These individual technologies work together as part of our strategy to minimize risk. This strategy is tested through audits and independent program assessments, as well as through additional exercises with our Managed Service Provider, designed to assess effectiveness. The Managed Service Provider actively manages our firewalls, multi-factor authentication, antivirus, and Azure environment. Our Managed Service Provider also reviews our cybersecurity program on a quarterly basis and provides recommendations toward best industry practice. Our cybersecurity program is continually evolving to align with NIST standards, and we regularly monitor our progression toward these standards.

Our Audit Committee is responsible for overseeing our cybersecurity and data privacy risks. Our cybersecurity program is led by the Hamilton Company’s Chief Financial Officer, who, along with the Hamilton Company’s Director of Information Technologywho has been with Hamilton for 39 years, provide regular updates each quarter to the Audit Committee regarding this program, including information about the cybersecurity threat landscape, investments in infrastructure and opportunities to protect and enhance the Company’s systems and security of products and operations. The also Board receives periodic briefings from management regarding cybersecurity activities and initiatives

The Partnership’s cybersecurity program is designed to safeguard the confidentiality, integrity and availability of data and systems within the Company’s environment to effectively support our business objectives and customer needs. Our commitment to cybersecurity focuses on enhancing our prevention, monitoring, and detection response capabilities to identify and respond to evolving threats. We believe cybersecurity is the responsibility of every employee of the Hamilton Company, and it is prioritized each year. We regularly test, educate, and share best practices with employees of the Hamilton Company to raise awareness of cyber threats through a comprehensive security awareness training program. Our Managed Service Provider is responsible for testing our ability to restore our critical infrastructure on a quarterly basis. Additionally, our incident response and disaster recovery plans are reviewed and updated annually.

During 2024, we have not encountered cybersecurity challenges that have materially impaired our operations, business strategy or financial condition.

Management started the construction project in 2024. In order to comply with the permanent financing requirements for a 40B project, Mill Street Development signed a term sheet for a loan of up to $15 million, to be funded upon completion of the development project. In addition, Mill Street Development deposited $75,000 into escrow to comply with the 40B project requirement of a cost certification of total development costs upon completion of the project.

Current free rent concessions would result in an average reduction in unit rents of approximately $3.42 per month per unit. Free rent expense amortized in 2024 was approximately $122,000 compared to approximately $76,000 in 2023.

General

On February 24, 2019, Harold Brown, the owner of 75% of the outstanding voting securities of NewReal, Inc. (“NewReal”), the general partner of New England Realty Associates Limited Partnership, passed away. As a result, the estate of Harold Brown held voting control over the capital stock of NewReal. On January 2, 2024, the estate was settled, with Jameson Brown and Harley Brown each assuming 37.5% ownership in NewReal. As of February 1, 2025, the Brown family related entities and Ronald Brown collectively own approximately 34.7% of the Depositary Receipts representing the Partnership Class A Units (including Depositary Receipts held by trusts for the benefit of such persons’ family members). Brown family related entities also control 75% of the Partnership’s Class B Units, and 75% of the capital stock of NewReal, the Partnership’s sole general partner. Ronald Brown also owns 25% of the Partnership’s Class B Units and 25% of the capital stock of NewReal. In addition, Ronald Brown is the President and a director of NewReal and Jameson Brown is Treasurer and a director of NewReal. Moreover, 75% of the issued and outstanding

Class B units of the Partnership are owned by HBC Holdings LLC, an entity of which Jameson Brown is the manager.The outstanding stock of The Hamilton Company is controlled by Jameson Brown and Harley Brown.

In the fiscal year ended December 31, 2022, the Partnership took advantage of the low interest rate environment and refinanced fifteen properties, increased their loan balances, and raised approximately $130,000,000. With interest rates rising, and a threat of an economic slowdown, the Partnership increased the debt level and built cash reserves to acquire additional properties when opportunities became available. Currently, approximately $84,000,000 of these reserves are invested in short-term US Treasury bills maturing in 6 months or less with interest rates between 4.19% and 5.02%.

Since the Partnership’s long-term goals include the acquisition of additional properties, a portion of the proceeds from the refinancing and sale of properties is reserved for this purpose. If available acquisitions do not meet the Partnership’s investment criteria, the Partnership may purchase additional Depositary Receipts. The Partnership will consider refinancing existing properties if the Partnership’s cash reserves are insufficient to repay existing mortgages or if the Partnership needs additional funds for future acquisitions.

The vacancy rate for the Partnership’s residential properties as of February 1, 2025 was 2.3% as compared with a vacancy rate of 0.9% as of February 1, 2024. The vacancy rate for the Joint Venture properties as of February 1, 2025 was 1.9%, as compared to 2.2% for the same period last year. The current vacancy rates are in line with those experienced prior to the Covid-19 Pandemic.

Residential tenants generally have lease terms of 12 months. The majority of these leases will mature during the second and third quarters of the year. Rental activity continues to be strong as we move from 2024 into 2025 and all indications are that we will have low vacancy rates for the foreseeable future.

During the fourth quarter of 2024, rents increased on average 5.7% for renewals and increased on average 0.2% for new leases. For all of 2024, renewal rents increased approximately 5.8% and increased approximately 4.8% for new leases. For 2025, management expects the local real estate market to remain stable as we move from the winter into the spring rental season.

The Partnership purchased a commercial retail property of approximately 20,700 square feet, located at 653 Worcester Road in Framingham, Massachusetts for approximately $10,151,000 on January 18, 2023. This acquisition was funded from the Partnership’s cash reserves and closing costs were approximately $59,000. From the purchase price, the Partnership allocated approximately $585,000 for in- place leases, and approximately $378,000 to the value of tenant relationships. These amounts are being amortized over 12 and 156 months respectively.

On July 14, 2023, the Partnership purchased a 52 unit mixed use property in the South End neighborhood of Boston, MA comprised of three buildings at 26-30 Rutland Street, 105-117 West Concord Street and 475 Shawmut Avenue, and approximately 3,400 square feet of commercial space for a purchase price of approximately $27,500,000. This acquisition was funded from the Partnership’s cash reserves and closing costs were approximately $81,000. From the purchase price, the Partnership allocated approximately $525,000 for in-place leases, approximately $61,000 to the value of tenant relationships and $241,000 to the value of below-market leases. These amounts are being amortized over 12 and 36 months, respectively.

For the year ending December 31, 2024 consolidated revenue increased by 8.1%, operating expenses decreased by 0.9% and Income before Other Income (Expense) increased by 34.8%. For the fourth quarter of 2024, consolidated revenue increased by 3.3%, operating expenses decreased by 8.2% and Income before Other Income (Expense) increased by 39.9%, as compared to the fourth quarter of 2023.

On June 16, 2022, the Partnership entered into an amendment to the Facility Agreement. The additional advance under the Amended Agreement is in the amount of $80,284,000, at a fixed interest rate of 4.33%. The Partnership’s obligations under the Facility Agreement are secured by mortgages on certain properties pursuant to certain Mortgage, Assignment of Leases and Rents, and Security Agreement and Fixture Filings.

The Partnership used the proceeds to pay down approximately $37,065,000 of existing debt secured by four properties, along with approximately $854,000 in prepayment penalties. The remaining balance of approximately $42,384,000 will be used for general partnership purposes.

On October 14, 2022, the Partnership entered into a loan agreement with Brookline Bank refinancing its loan on 659-665 Worcester Road, Framingham, MA. The agreement pays down the loan on the existing debt of $5,954,546, extends the maturity until October 14, 2032 at a variable interest rate of the SOFR rate plus 1.7%, interest only for 2 years and amortizing using a thirty-year schedule for the balance of the term. At closing, the Partnership entered into an interest rate swap contract with Brookline Bank with a notional amount equivalent to the underlying loan principal amortization, resulting in a fixed rate of 4.60% through the expiration of the interest rate swap contract. The agreement also allows for an earn out of up to an additional $1,495,453 once the property performance reaches a 1.35x debt service coverage ratio and the loan to value equates to at most 65%.

On July 31, 2014, the Partnership entered into an agreement for a $25,000,000 revolving line of credit. The term of the line was for three years with a floating interest rate equal to a base rate of the greater of (a) the Prime Rate (b) the Federal Funds Rate plus one-half of one percent per annum, or (c) the LIBOR Rate for a period of one month plus 1% per annum, plus an applicable margin of 2.5%. The agreement originally expired on July 31, 2017, and was subsequently extended until October 31, 2020. The costs associated with the line of credit extension were approximately $128,000.

On October 29, 2021, the Partnership closed on the modification of its existing line of credit. The agreement extended the line of credit until October 29, 2024. The commitment amount was for $25 million but was restricted to $17 million during the modification period. The modification period was phased out by December 31, 2022. During this period, the loan covenants were modified from a minimum consolidated debt service ratio of 1.60 to a ratio of 1.35 until September 30, 2022; from a minimum tangible net worth requirement of $200 million to a net worth of $175 million until September 30, 2022; from a maximum consolidated leverage ratio of 65% to a ratio of 70% until September 30, 2022 and from a minimum debt yield of 9.5% to a yield of 8.5% until September 30, 2022 and a yield of 9.0% until December 31, 2022. Once the financial performance of the Partnership met the original covenant tests for the trailing 12-month period, the commitment amount would return to $25 million. The portfolio’s debt yield fell below the minimum of 9.0% to 8.6%. Consequently, as of December 31, 2023, the Partnership did not comply with the debt yield financial covenant. As such, the Partnership was restricted from drawing down any amount from the line of credit until the Partnership met the required financial covenants.

On November 21, 2024, the Partnership entered into an agreement for a new $25,000,000 revolving line of credit. The term of the line is for three years with a floating interest rate equal to a base rate of the SOFR Rate for a period of one month plus the applicable margin of 2.5%. The loan covenants include a leverage ratio not to exceed 65%, a debt service coverage ratio of not less than 1.5 to 1.0, maximum usage of 1.5 times trailing 12 months EBITDA, minimum liquidity of $15 million, and a minimum debt yield of 8.5%. The Partnership incurred a commitment fee of $125,000. The Partnership will be charged annually an unused line fee, equal to seventy-five basis points (0.75%) between the difference of the maximum availability and the outstanding principal of the line of credit. This fee will be waived for any period in which the Partnership maintains aggregate deposits of twenty million dollars with the Lender. As of December 31, 2024, the Partnership was in compliance with the financial covenants and did not incur an unused line fee.

The Repurchase Program that was initiated in 2007 has purchased 1,550,358 Depositary Receipts through December 31, 2024, or approximately 36% of the outstanding Depositary Receipts. The Partnership purchased 18,124 Depositary Receipts in 2024.

In March of 2020, the Board of Advisors and Board of Directors unanimously approved an extension of the Repurchase Program until March 31, 2025. On March 12, 2025, the Board of Directors unanimously approved a new extension to the Repurchase Program, authorizing the President and Treasurer to cause the Partnership to repurchase, on the open market or otherwise, including through individually negotiated purchases and through a written trading plan that complies with the requirements of Rule 10b5-1, Depository Receipts and Partnership Units such that (i) the aggregate cost of Depository Receipts and Partnership Units repurchased shall not exceed the lesser of $5 million or 10% of the Partnership’s balance of cash and investment in treasury bills, (ii) no Depository Receipts or Partnership Units

29

Table of Contents

shall be repurchased after the date that is 12 months after the effective date of the plan, and (iii) no Depository Receipts or Partnership Units shall be repurchased in excess of $95 per Depository Receipt. The Repurchase Plan requires the Partnership to repurchase a proportionate number of Class B Units and General Partner Units in connection with any repurchases of any Depositary Receipts by the Partnership based upon the 80%, 19% and 1% fixed distribution percentages of the holders of the Class A, Class B and General Partner Units under the Partnership Agreement. This repurchase authorization replaces the Partnership’s previous repurchase program. The Repurchase Plan shall be made in accordance with the terms of Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and shall be made in accordance with all applicable laws and regulations in effect from time to time.

Management believes that the $25,000,000 line of credit, net cash flow from operations and cash on hand have put the Partnership in position to capitalize on investment opportunities should they reveal themselves in the near future. As always, management continues to weigh investment alternatives of stock repurchase, new property acquisitions and dispositions when considering its cash balances and performance of the portfolio.

The Partnership has retained the Hamilton Company (“Hamilton”) to manage and administer the Partnership’s and Joint Ventures’ Properties. Hamilton is a full-service real estate management company, which has legal, construction, maintenance, architectural, accounting and administrative departments. The Partnership’s properties represent approximately 44% of the total properties and 50% of the residential properties managed by Hamilton. Substantially all of the other properties managed by Hamilton are owned, wholly or partially, directly or indirectly, by the Brown Family related entities. The Partnership’s Second Amended and Restated Contract of Limited Partnership (the “Partnership Agreement”) expressly provides that the general partner may employ a management company to manage the properties, and that such management company may be paid a fee of up to 4% of rental receipts for administrative and management services (the “Management Fee”). The Partnership pays Hamilton the annual Management Fee in monthly installments.

In addition to the Management Fee, the Partnership Agreement further provides for the employment of outside professionals to provide services to the Partnership and allows the General Partner to charge the Partnership for the cost of employing professionals to assist with the administration of the Partnership’s properties. Additionally, from time to time, the Partnership pays Hamilton for repairs and maintenance services, legal services, construction services and accounting services. The costs charged by Hamilton for these services are at the same hourly rate charged to all entities managed by Hamilton, and management believes such rates are competitive in the marketplace.

In 2024, tenant renewals were approximately 68% with an average rental increase of approximately 5.8%. New leases accounted for approximately 32% with rental rate increases of approximately 4.8%.

Hamilton accounted for approximately 1.3% of the repair and maintenance expense paid for by the Partnership in the year ended December 31, 2024 and 2.0% in the year ended December 31, 2023. Of the funds paid to Hamilton for this purpose, the great majority was to cover the cost of services provided by the Hamilton maintenance department, including plumbing, electrical, carpentry services, and snow removal for those properties close to Hamilton’s headquarters. Several of the larger Partnership properties have their own maintenance staff. Those properties that do not have their own maintenance staff and are located more than a reasonable distance from Hamilton’s headquarters in Allston, Massachusetts are generally serviced by local, independent companies.

Hamilton’s legal department handles most of the Partnership’s eviction and collection matters. Additionally, Hamilton prepares most long-term commercial lease agreements and represents the Partnership in selected purchase and sale transactions. Overall, Hamilton provided approximately 42.5% and 63.9% of the legal services paid for by the Partnership during the years ended December 31, 2024 and 2023, respectively.

Additionally, as described in Note 3 to the Consolidated Financial Statements, the Hamilton Company receives similar fees from the Investment Properties.

The Partnership requires that three bids be obtained for construction contracts in excess of $15,000. Hamilton may be one of the three bidders on a particular project and may be awarded the contract if its bid and its ability to successfully complete the project are deemed appropriate. For contracts that are not awarded to Hamilton, Hamilton charges the Partnership a construction supervision fee equal to 5% of the contract amount. Hamilton’s architectural department also provides services to the Partnership on an as-needed basis. In 2024, Hamilton provided the Partnership approximately $504,000 in construction and architectural services, compared to $606,000 for the year ended December 31, 2023.

Bookkeeping and accounting functions have been provided by Hamilton’s accounting staff, which consists of approximately 14 people. In 2024, Hamilton charged the Partnership $125,000 per year ($31,250 per quarter) for bookkeeping and accounting services. For more information on related party transactions, see Note 3 to the Consolidated Financial Statements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of the consolidated financial statements, in accordance with accounting principles generally accepted in the United States of America, requires the Partnership to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. The Partnership regularly and continually evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate properties and its investments in and advances to joint ventures. The Partnership bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. However, because future events and their effects cannot be determined with certainty, the determination of estimates requires the exercise of judgment. The Partnership’s critical accounting policies are those which require assumptions to be made about such matters that are highly uncertain. Different estimates could have a material effect on the Partnership’s financial results. Judgments and uncertainties affecting the application of these policies and estimates may result in materially different amounts being reported under different conditions and circumstances. See Note 1 to the Consolidated Financial Statements, Principles of Consolidation.

Revenue Recognition: Rental income from residential and commercial properties is recognized over the term of the related lease. For residential tenants, amounts 60 days in arrears are charged against income. The commercial tenants are evaluated on a case by case basis. Certain leases of the commercial properties provide for increasing stepped minimum rents, which are accounted for on a straight-line basis over the term of the lease. Concessions made on residential leases are also accounted for on the straight-line basis.

Above-market and below-market lease values for acquired properties are initially recorded based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the differences between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed-rate renewal options for below-market leases. The capitalized above-market lease amounts are accounted for as a reduction of base rental revenue over the remaining term of the respective leases, and the capitalized below-market lease values are amortized as an increase to base rental revenue over the remaining initial terms plus the terms of any below-market fixed-rate renewal options of the respective leases.

The Partnership evaluates the non-lease components (lease arrangements that include common area maintenance services) with related lease components (lease revenues). If both the timing and pattern of transfer are the same for the non-lease component and related lease component, the lease component is the predominant component. The Partnership elected an allowed practical expedient. For (i) operating lease arrangements involving real estate that include common area maintenance services and (ii) all real estate arrangements that include real estate taxes and insurance costs, we present these amounts within lease revenues in our consolidated statements of income. We record amounts reimbursed by the lessee in the period in which the applicable expenses are incurred.

RentalPropertyHeld for sale: When assets are identified by management as held for sale, the Partnership discontinues depreciating the assets and estimates the sales price, net of selling costs, of such assets. The Partnership

31

Table of Contents

generally considers assets to be held for sale when the transaction has received appropriate corporate authority, and there are no significant contingencies relating to the sale. If, in management’s opinion, the estimated net sales price, net of selling costs, of the assets which have been identified as held for sale is less than the carrying value of the assets, a valuation allowance is established.

If circumstances arise that previously were considered unlikely and, as a result, the Partnership decides not to sell a property previously classified as held for sale, the property is reclassified as held and used. A property that is reclassified is measured and recorded individually at the lower of (a) its carrying value before the property was classified as held for sale, adjusted for any depreciation (amortization) expense that would have been recognized had the property been continuously classified as held and used, or (b) the fair value at the date of the subsequent decision not to sell.

Rental Properties: Rental properties are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred; improvements and additions are capitalized. When assets are retired or otherwise disposed of, the cost of the asset and related accumulated depreciation is eliminated from the accounts, and any gain or loss on such disposition is included in income. Fully depreciated assets are removed from the accounts. Rental properties are depreciated by both straight-line and accelerated methods over their estimated useful lives. Upon acquisition of rental property, the Partnership estimates the fair value of acquired tangible assets, consisting of land, building and improvements, and identified intangible assets and liabilities assumed, generally consisting of the fair value of (i) above and below market leases, (ii) in-place leases and (iii) tenant relationships. The Partnership allocated the purchase price to the assets acquired and liabilities assumed based on their fair values. The Partnership records goodwill or a gain on bargain purchase (if any) if the net assets acquired/liabilities assumed exceed the purchase consideration of a transaction. In estimating the fair value of the tangible and intangible assets acquired, the Partnership considers information obtained about each property as a result of its due diligence and marketing and leasing activities, and utilizes various valuation methods, such as estimated cash flow projections utilizing appropriate discount and capitalization rates, estimates of replacement costs net of depreciation, and available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. Costs directly related to the acquisition, development and construction of rental properties are capitalized. Capitalized development and construction costs include pre-construction costs, development and construction costs, regulatory fees, interest, property taxes, insurance, construction oversight fees, and other project costs incurred during the period of development. The Partnership considers a construction project as substantially completed and held available for occupancy upon the substantial completion of improvements, but no later than one year from cessation of major construction activity.

Investments in Treasury Bills:Investments in Treasury Bills are recorded at amortized cost and classified as held to maturity as the Partnership has the intent and the ability to hold them until they mature. The carrying value of the Treasury Bills is adjusted for accretion of discounts over the remaining life of the investment. Income related to the Treasury Bills is recognized in interest income in the Partnership’s consolidated statement of income.

Intangible assets acquired include amounts for in-place lease values above and below market leases and tenant relationship values, which are based on management’s evaluation of the specific characteristics of each tenant’s lease and the Partnership’s overall relationship with the respective tenant. Factors to be considered by management in its analysis of in-place lease values include an estimate of carrying costs during hypothetical expected lease-up periods considering current market conditions, and costs to execute similar leases at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, management considers leasing commissions, legal and other related expenses. Characteristics considered by management in valuing tenant relationships include the nature and extent of the Partnership’s existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality and expectations of lease renewals. The value of in- place leases is amortized to expense over the remaining initial terms of the respective leases. The value of tenant relationship intangibles is amortized to expense over the anticipated life of the relationships.

In the event that facts and circumstances indicate that the carrying value of a rental property may be impaired, an analysis of the value is prepared. The estimated future undiscounted cash flows are compared to the asset’s carrying value to determine if a write-down to fair value is required.

Impairment: On an annual basis management assesses whether there are any indicators that the value of the Partnership’s rental properties may be impaired. A property’s value is impaired only if management’s estimate of the aggregate future cash flows (undiscounted and without interest charges) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying amount of the property over the fair value of the property. The Partnership’s estimates of aggregate future cash flows expected to be generated by each property are based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for tenants, changes in market rental rates, and costs to operate each property. As these factors are difficult to predict and are subject to future events that may alter management’s assumptions, the future cash flows estimated by management in its impairment analysis may not be achieved.

Investments in Joint Ventures: The Partnership accounts for its 40%-50% ownership in the Investment Properties under the equity method of accounting, as it exercises significant influence over, but does not control these entities. These investments are recorded initially at cost, as Investments in Joint Ventures, and subsequently adjusted for the Partnership’s share in earnings, cash contributions and distributions. Under the equity method of accounting, our net equity is reflected on the consolidated balance sheets, and our share of net income or loss from the Partnership is included on the consolidated statements of income. Generally, the Partnership would discontinue applying the equity method when the investment (and any advances) is reduced to zero and would not provide for additional losses unless the Partnership has guaranteed obligations of the venture or is otherwise committed to providing further financial support for the investee. If the venture subsequently generates income, the Partnership only recognizes its share of such income to the extent it exceeds its share of previously unrecognized losses.

The authoritative guidance on consolidation provides guidance on the identification of entities for which control is achieved through means other than voting rights (“variable interest entities” or “VIEs”) and the determination of which business enterprise, if any, should consolidate the VIE (the “primary beneficiary”). Generally, the consideration of whether an entity is a VIE applies when either (1) the equity investors (if any) lack one or more of the essential characteristics of a controlling financial interest, (2) the equity investment at risk is insufficient to finance that equity’s activities without additional subordinated financial support or (3) the equity investors have voting rights that are not proportionate to their economic interests and the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest. The primary beneficiary is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the variable interest entity’s performance; and (2) the obligation to absorb losses and rights to receive the returns from VIE that would be significant to the VIE.

With respect to investments in and advances to the Investment Properties, the Partnership looks to the underlying properties to assess performance and the recoverability of carrying amounts for those investments in a manner similar to direct investments in real estate properties. An impairment charge is recorded if management’s estimate of the aggregate future cash flows (undiscounted and without interest charges) to be generated by the property is less than the carrying value of the property.

Legal Proceedings: The Partnership is subject to various legal proceedings and claims that arise, from time to time, in the ordinary course of business. These matters are frequently covered by insurance. If it is determined that a loss is likely to occur, the estimated amount of the loss is recorded in the financial statements. Both the amount of the loss and the point at which its occurrence is considered likely can be difficult to determine.

Rental income from continuing operations for the year ended December 31, 2024 was approximately $79,763,000, compared to approximately $73,892,000 for the year ended December 31, 2023, an increase of approximately $5,871,000 (7.9%). Excluding the net increase in revenue from Shawmut of approximately $1,270,000, there was an increase of approximately $4,601,000 (6.3%).

The Partnership Properties with the largest increases in rental income include Hamilton Oaks, 62 Boylston Street Apartments, Mill Street Gardens, 659 Worcester Road, and 1144 Commonwealth Apartments, with increases of approximately $522,000, $446,000, $393,000, $337,000 and $303,000, respectively. Included in rental income is contingent rentals collected on commercial properties. Contingent rentals include such charges as bill backs of common area maintenance charges, real estate taxes, and utility charges.

Total expenses from continuing operations for the year ended December 31, 2024 were approximately $55,161,000 compared to approximately $55,666,000 for the year ended December 31, 2023, a decrease of approximately $505,000 (0.9%). Excluding the net change in expenses from Shawmut’s of approximately $953,000, there was a decrease of approximately $1,458,000 (2.7%). Factors which contributed to the decrease were a decrease of approximately $971,000, for the Impairment charge in 2023 for Mill Street Development, a decrease in Depreciation and Amortization expense of approximately $480,000 (0.9%), due to fully depreciated assets, and a decrease in Repairs and Maintenance expense of approximately $340,000 (0.6%), primarily due to a decrease in window, door, and glass repairs

Interest income for the year ended December 31, 2024 was approximately $4,466,000 compared to approximately $4,487,000 for the year ended December 31, 2023, a decrease of approximately $21,000. The decrease is due to a decrease in interest rates for investments in Treasury Bills which mature over a period less than 180 days, with interest rates between 4.2% to 5.0%.

Interest expense for the year ended December 31, 2024 was approximately $15,457,000 compared to approximately $15,723,000 for the year ended December 31, 2023, a decrease of approximately $266,000 (1.7%). The decrease is due to the greater amortization of principal for debt with level principal and interest payments.

At December 31, 2024, the Partnership has between a 40% and 50% ownership interests in seven different Investment Properties. See a description of these properties included in the section titled Investment Properties as well as Note 15 to the Consolidated Financial Statements for a detail of the financial information of each Investment Property.

As described in Note 15 to the Consolidated Financial Statements, the Partnership’s share of the net income from the Investment Properties was approximately $1,282,000 for the year ended December 31, 2024, compared to net income of approximately $876,000 for the year ended December 31, 2023, an increase in income of approximately $406,000 (46.3%). This increase is primarily due to rental revenue of approximately $11,689,000 for the year ended December 31, 2024 compared to approximately $11,132,000 for the year ended December 31, 2023, an increase of approximately $557,000 (5.0%). Included in the income for the year ended December 31, 2024 is depreciation and amortization expense of approximately $2,617,000.

As a result of the changes discussed above, net income for the year ended December 31, 2024 was approximately $15,662,000 compared to net income of approximately $8,454,000 for the year ended December 31, 2023, an increase in income of approximately $7,208,000 (85.3%).
