FINANCIAL STATEMENTS ​ March 31, 2023 ​ (Unaudited) ​ NOTE 1. SIGNIFICANT ACCOUNTING POLICIES ​ Line of Business : New England Realty Associates Limited Partnership (“NERA”, the “Company” or the “Partnership”) was organized in Massachusetts in 1977. NERA and its subsidiaries own 30 properties which include 21 residential buildings; 4 mixed use residential, retail and office buildings; 5 commercial buildings and individual units at one condominium complex. These properties total 2,892 apartment units, 19 condominium units and 128,096 square feet of commercial space. Additionally, the Partnership also owns a 40 - 50 % interest in 7 residential and mixed use properties consisting of 688 apartment units, 12,500 square feet of commercial space and a 50 car parking lot. The properties are located in Eastern Massachusetts and Southern New Hampshire. ​ Basis of Presentation: The financial statements have been prepared in conformity with GAAP. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. These estimates and assumptions are based on management’s historical experience that are believed to be reasonable at the time. However, because future events and their effects cannot be determined with certainty, the determination of estimates requires the exercise of judgement. The Partnership’s critical accounting policies are those which require assumptions to be made about matters that are highly uncertain. Different estimates could have a material effect on the Partnership’s financial results. Judgements and uncertainties affecting the application of these policies and estimates may result in materially different amounts being reported under different conditions and circumstances. Principles of Consolidation : The consolidated financial statements include the accounts of NERA and its subsidiaries. NERA has a 99.67 % to 100 % ownership interest in each subsidiary except for the seven limited liability companies (the “Investment Properties” or “Joint Ventures”) in which the Partnership has a 40 - 50 % ownership interest. The consolidated group is referred to as the “Partnership”. Minority interests are not recorded, since they are insignificant. All significant intercompany accounts and transactions are eliminated in consolidation. The Partnership accounts for its investment in the above-mentioned Investment Properties using the equity method of consolidation. (See Note 15: Investment in Unconsolidated Joint Ventures.) ​ The Partnership accounts for its investments in joint ventures using the equity method of accounting. These investments are recorded initially at cost, as Investments in Unconsolidated Joint Ventures, and subsequently adjusted for equity in earnings and cash contributions and distributions. 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. In 2013 and beyond, the carrying values of some investments fell below zero. We intend to fund our share of the investments’ future operating deficits should the need arise. However, we have no legal obligation to pay for any of the liabilities of such investments nor do we have any legal obligation to fund operating deficits. (See Note 15: Investment in Unconsolidated Joint Ventures.) ​ 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 9 Table of Contents 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. ​ Impairment: On an annual basis management assesses whether there are any indicators that the value of the Partnership’s rental properties or investments in unconsolidated subsidiaries may be impaired. In addition to identifying any specific circumstances which may affect a property or properties, management considers other criteria for determining which properties may require assessment for potential impairment. The criteria considered by management include reviewing low leased percentages, significant near term lease expirations, recently acquired properties, current and historical operating and/or cash flow losses, near term mortgage debt maturities or other factors that might impact the Partnership’s intent and ability to hold property. 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 analyses may not be achieved. ​ 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. Revenue from commercial leases also include reimbursements and recoveries received from tenants for certain costs as provided in the lease agreement. The costs generally include real estate taxes, utilities, insurance, common area maintenance and recoverable costs. Rental concessions 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. ​ Rental Properties: Rental properties are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred; improvements and additions which improve or extend the life of the assets 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 10 Table of Contents 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. ​ Other intangible assets acquired include amounts for in-place lease values 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 are amortized to expense over the remaining initial terms of the respective leases. The value of tenant relationship intangibles are 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. ​ Leasing Fees: Leasing fees are capitalized and amortized on a straight-line basis over the life of the related lease. Unamortized balances are expensed when the corresponding fee is no longer applicable. ​ Deferred Financing Costs : Costs incurred in obtaining financing are capitalized and amortized over the term of the related indebtedness. Deferred financing costs are presented in the balance sheet as a direct deduction from the carrying value of the debt liability to which they relate, except deferred financing costs related to the revolving credit facility, which are presented in prepaid expenses and other assets. In all cases, amortization of such costs is included in interest expense and was approximately $ 95,000 and $ 90,000 for the three months ended March 31, 2023 and 2022, respectively. ​ Income Taxes: The financial statements have been prepared on the basis that NERA and its subsidiaries are entitled to tax treatment as partnerships. Accordingly, no provision for income taxes have been recorded (See Note 14). ​ Cash Equivalents: The Partnership considers cash equivalents to be all highly liquid instruments purchased with a maturity of three months or less at the time of purchase. ​ 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 are 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. ​ Segment Reporting: Operating segments are revenue producing components of the Partnership for which separate financial information is produced internally for management. Under the definition, NERA operated, for all periods presented, as one segment. ​ Other Comprehensive Income (Loss): Other comprehensive income (loss) includes items that are recorded in equity, such as effective portions of derivatives designated as cash flow hedges or unrealized holding gains or losses on marketable securities available for sale. NERA had a comprehensive loss of approximately $166,000 for the three months ended March 31, 2023, but had no comprehensive income or loss for the three months ended March 31, 2022. ​ Income (Loss) Per Depositary Receipt: Effective January 3, 2012, the Partnership authorized a 3 -for-1 forward split of its Depositary Receipts listed on the NYSE Amex and a concurrent adjustment of the exchange ratio of Depositary Receipts for Class A Units of the Partnership from 10 -to-1 to 30 -to-1, such that each Depositary Receipt represents one-thirtieth ( 1 / 30 ) of a Class A Unit of the Partnership. All references to Depositary Receipts in the report are reflective of the 3-for-1 forward split. ​ 11 Table of Contents Income Per Unit: Net income per unit has been calculated based upon the weighted average number of units outstanding during each period presented. The Partnership has no dilutive units and, therefore, basic net income is the same as diluted net income per unit (see Note 7: Partner’s Capital). ​ Concentration of Credit Risks and Financial Instruments: The Partnership’s properties are located in New England, and the Partnership is subject to the general economic risks related thereto. No single tenant accounted for more than 5 % of the Partnership’s revenues in 2023 or 2022. The Partnership makes its temporary cash investments with high-credit quality financial institutions. At March 31, 2023, substantially all of the Partnership’s cash and cash equivalents were held in interest-bearing accounts at financial institutions, and investments in U.S. Treasury bills, earning interest at rates from 0.01 % to 4.75 %. At March 31, 2023 and December 31, 2022, respectively approximately $ 25,063,000 , and $ 49,641,000 of cash and cash equivalents, and security deposits included in prepaid expenses and other assets exceeded federally insured amounts. Of the $ 25,063,000 , approximately $ 9,885,000 is invested in U.S. Treasury bills maturing in three months. ​ Advertising Expense: Advertising is expensed as incurred. Advertising expense was approximately $ 109,000 and $ 73,000 for the three months ended March 31, 2023, and 2022, respectively. Rental Property Held f or 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 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. Interest Capitalized: The Partnership follows the policy of capitalizing interest as a component of the cost of rental property when the time of construction exceeds one year . During the three months ended March 31, 2023, and 2022 there was no capitalized interest. ​ Extinguishment of Debt: When existing mortgages are refinanced with the same lender and it is determined that the refinancing is substantially different, then they are recorded as an extinguishment of debt. However, if it is determined that the refinancing is substantially the same, then they are recorded as an exchange of debt. All refinancings qualify as extinguishment of debt. ​ Reclassification: Certain reclassifications have been made to prior period amounts in order to conform to current period presentation. ​ NOTE 2. RENTAL PROPERTIES ​ As of March 31, 2023, the Partnership and its Subsidiary Partnerships owned 2,892 residential apartment units in 25 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 referred to as the “Condominium Units”). The Apartment Complexes and Condominium Units are located primarily in the metropolitan Boston area of Massachusetts. ​ Additionally, as of March 31, 2023, the Partnership and Subsidiary Partnerships owned two commercial shopping centers in Framingham, commercial buildings in Newton and Brookline and mixed-use properties in Boston, Brockton, and Newton, all in Massachusetts. These properties are referred to collectively as the “Commercial Properties.” ​ The Partnership also owned a 40 % to 50 % ownership interest in seven residential and mixed use complexes (the “Investment Properties”) at March 31, 2023 with a total of 688 apartment units, accounted for using the equity method of consolidation. See Note 15 for summary information on these investments. ​ The Partnership purchased a commercial retail property of approximately 20,700 square feet, located at 653 Worcester Road in Framingham, Massachusetts for the sum of approximately $ 10,151,000 on January 18, 2023. This acquisition was funded from the Partnership’s cash reserves and c losing costs were approximately $ 59,000 .

FAIR VALUE MEASUREMENTS ​ Fair Value Measurements on a Recurring Basis ​ At March 31, 2023 and December 31, 2022, we do not have any significant financial assets or financial liabilities that are measured at fair value on a recurring basis in our consolidated financial statements. ​ Financial Assets and Liabilities not Measured at Fair Value ​ At March 31, 2023 and December 31, 2022 the carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable, and note payable, accounts payable and accrued expenses were representative of their fair values due to the short-term nature of these instruments or, the recent acquisition of these items. The Company considers all highly liquid investments purchased with original maturities of three months or less at the time of purchase to be cash equivalents. Cash, cash equivalents, and restricted cash include cash held in checking, U.S. Treasury Bills, and money market accounts. ​ The Partnership has investments in Treasury Bills some of which mature over a period greater than 90 days and are classified as short-term investments. The Treasury Bills are carried 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 are 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. The Treasury Bills classified within Level I of the fair value hierarchy. ​ At March 31, 2023 and December 31, 2022 we estimated the fair value of our mortgages payable and other notes based upon quoted market prices for the same (Level 1) or similar (Level 2) issues when current quoted market prices are available. We estimated the fair value of our secured mortgage debt that does not have current quoted market prices available by discounting the future cash flows using rates currently available to us for debt with similar terms and 18 Table of Contents maturities (Level 3). The differences in the fair value of our debt from the carrying value are the result of differences in interest rates and/or borrowing spreads that were available to us at March 31, 2023 and December 31, 2021, as compared with those in effect when the debt was issued or acquired. The secured mortgage debt contain pre-payment penalties or yield maintenance provisions that could make the cost of refinancing the debt at lower rates exceed the benefit that would be derived from doing so. At March 31, 2023 and at December 31, 2022 the Partnership’s line of credit had an outstanding balance of zero . ​ The following methods and assumptions were used by the Partnership in estimating the fair value of its financial instruments: ​ ● For cash and cash equivalents, accounts receivable, other assets, investment in partnerships, accounts payable, advance rents and security deposits: fair value approximates the carrying value of such assets and liabilities. ​ ● For mortgage notes payable: fair value is generally based on estimated future cash flows, which are discounted using the quoted market rate from an independent source for similar obligations. Refer to the table below for the carrying amount and estimated fair value of such instruments. ​ The following table reflects the carrying amounts and estimated fair value of our debt. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2023 Dec 31, 2022 ​ ​ Carrying Value Fair Value ​ Carrying Value Fair Value Assets ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents ​ 24,654,625 ​ 24,654,625 ​ 49,560,723 ​ 49,560,723 Treasury bills ​ 97,759,876 ​ 98,616,960 ​ 88,332,133 ​ 88,908,540 Total Assets ​ 122,414,501 ​ 123,271,585 ​ 137,892,856 ​ 138,469,263 ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ ​ Mortgage payable * ​ ​ ​ ​ ​ ​ ​ ​ - Partnership properties ​ 410,449,284 ​ 369,932,494 ​ 410,966,199 ​ 355,629,060 - Investment properties ​ 166,061,428 ​ 158,229,915 ​ 166,090,966 ​ 153,710,522 Total Liabilities ​ 576,510,712 ​ 528,162,409 ​ 577,057,165 ​ 509,339,582 * Net of unamortized deferred financing costs ​ Disclosure about fair value of financial instruments is based on pertinent information available to management as of March 31, 2023 and December 31, 2022. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since March 31, 2023 and current estimates of fair value may differ significantly from the amounts presented herein. ​ NOTE 13. DERIVATIVE FINANCIAL INSTRUMENTS Cash Flow Hedges of Interest Rate Risk The Partnership’s objectives in using rate derivatives are to manage its exposure to interest rate movements. To accomplish this objective, the Partnership uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Partnership making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Partnership’s variable rate debt. During the next 12 months, the Partnership estimates $ 114,000 will be reclassified as a decrease to interest expense. 19 Table of Contents As of March 31, 2023, the Partnership had one interest rate swap outstanding with a notional amount of approximately $ 129,000 designated as cash flow hedges of interest rate risk.

TAXABLE INCOME AND TAX BASIS ​ Taxable income reportable by the Partnership and includable in its partners’ tax returns is different than financial statement income because of tax free exchanges, different depreciation methods, different tax lives, other items with limited tax deductibility carryovers and timing differences related to prepaid rents, allowances and intangible assets at significant acquisitions. Federal taxable income of approximately $ 10,968,000 was approximately $ 7,245,000 more than statement income for the year ended December 31, 2022. The Federal cumulative tax basis of the Partnership’s real estate at December 31, 2022 is approximately $ 14,000,000 more than the statement basis. The primary reasons for the difference in tax basis are tax free exchanges, accelerated depreciation and bonus depreciation. The Partnership’s Federal tax basis in its joint venture investments is approximately $ 3,000,000 more than statement basis. State taxable income may be significantly different due to different tax treatments for certain items. Certain entities included in the Partnership’s consolidated financial statements are subject to certain state taxes.

The Partnership adopted the amended provisions related to uncertain tax provisions of ASC 740, Income Taxes.

Participants are always 100 percent vested in their pre-tax contributions and will begin vesting in any matching or profit-sharing contributions made on their behalf after two years of service with the Partnership at a rate of 20 percent per year, becoming 100 percent vested after a total of six years of service with the Partnership.
