["Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]","1. Organization Clipper Realty Inc. (the “Company” or “We”) was organized in the state of Maryland on July 7, 2015. On August 3, 2015, we completed certain formation transactions and the sale of shares of common stock in a private offering. We contributed the net proceeds of the private offering to Clipper Realty L.P., our operating partnership subsidiary (the “Operating Partnership”), in exchange for units in the Operating Partnership. The Operating Partnership in turn contributed such net proceeds to the limited liability companies (“LLCs”) that comprised the predecessor of the Company in exchange for Class A LLC units in such LLCs and became the managing member of such LLCs. The owners of the LLCs exchanged their interests for Class B LLC units and an equal number of special, non-economic, voting stock in the Company. The Class B LLC units, together with the special voting shares, are convertible into common shares of the Company on a one-for-one On June 27, 2016, the Operating Partnership acquired the Aspen property located at 1955 First Avenue in Manhattan, New York. On February 9, 2017, the Company priced an initial public offering of 6,390,149 primary shares of its common stock (including the exercise of the over-allotment option, which closed on March 10, 2017) at a price of $13.50 per share (the “IPO”). The net proceeds of the IPO were approximately $79,000. We contributed the proceeds of the IPO to the Operating Partnership, in exchange for units in the Operating Partnership. On May 9, 2017, the Company completed the purchase of 107 Columbia Heights (subsequently renovated and rebranded “Clover House”), a 158-unit apartment building located in the Brooklyn Heights neighborhood of Brooklyn, New York. On October 27, 2017, the Company completed the acquisition of an 82-unit residential property at 10 West 65th Street in the Upper West Side neighborhood of Manhattan, New York. On November 8, 2019, the Company completed the acquisition of 1010 Pacific Street located in the Prospect Heights neighborhood of Brooklyn, New York; the Company redeveloped the property into a 175-unit residential building. During the period December 2021 through February 2022, the Company purchased the Dean Street property which consists of multiple parcels of land in the Prospect Heights neighborhood of Brooklyn, New York; the Company plans to redevelop the property as a 240-unit residential building with two ground floor retail units. As of December 31, 2024, the properties owned by the Company consist of the following (collectively, the “Properties”):\n•\nTribeca House in Manhattan, comprising two\n•\nFlatbush Gardens in Brooklyn, a 59-building residential housing complex with 2,494 rentable units;\n•\n141 Livingston Street in Brooklyn, a 15-story office building with approximately 216,000 square feet of GLA;\n•\n250 Livingston Street in Brooklyn, a 12-story office and residential building with approximately 370,000 square feet of GLA (fully remeasured);\n•\nAspen in Manhattan, a 7-story building containing residential and retail space with approximately 166,000 square feet of residential rental GLA and approximately 21,000 square feet of retail rental GLA;\n•\nClover House in Brooklyn, a 11-story residential building with approximately 102,000 square feet of residential rental GLA;\n•\n10 West 65th Street in Manhattan, a 6-story residential building with approximately 76,000 square feet of residential rental GLA;\n•\n1010 Pacific Street in Brooklyn, 9-story residential building with approximately 119,000 square feet of residential rental GLA; and\n•\nthe Dean Street property in Brooklyn, which the Company plans to redevelop as a 9-story residential building with approximately 160,000 square feet of residential rental GLA and approximately 9,000 square feet of retail rental GLA. Square footage, leased occupancy percentage and rentable unit disclosures in the consolidated financial statements are unaudited. During 2019, we entered into a joint venture in which we own a 50% interest through which we are paying certain legal and advisory expenses in connection with various rent laws and ordinances which govern certain of our properties. During the year ended December 31, 2024, the Company incurred $787 of such expenses, which was recorded as part of general and administrative in the Consolidated Statements of Operations, and the Company has fulfilled its commitment to the joint venture. On June 29, 2023 the Company’s Flatbush Gardens property entered into a 40 year regulatory agreement under Article 11 of the Private Housing Finance Law with the New York City Department of Housing Preservation and Development (“Article 11Agreement”). For the full term of the agreement, Flatbush Gardens received a full exemption from property taxes, committed to maintain rents with existing area median income groups, received eligibility for incremental rental assistance payments under Section 610 of the Private Housing Financing Law for tenants receiving government rental assistance, committed to lease 249 units to formerly homeless families and provide certain services as units become vacant, and committed to pay prevailing wage rates to employees of the property as defined under New York City regulations. The property also committed to a 3-year capital improvements plan. As part of the agreement, a new not-for-profit Corporation, Flatbush Gardens Housing Development Fund Corporation (“HDFC”), became the nominal owner of the Flatbush Gardens properties. This has no effect on the beneficial operations and finances of the properties but provides HDFC with certain consent rights for transfers and financings of the properties. (See Note 7 Commitments and Contingencies). The operations of Clipper Realty Inc. and its consolidated subsidiaries are carried on primarily through the Operating Partnership. The Company has elected to be taxed as a Real Estate Investment Trust (“REIT”) under Sections 856 through 860 of the Internal Revenue Code (the “Code”). The Company is the sole general partner of the Operating Partnership and the Operating Partnership is the sole managing member of the LLCs that comprised the Predecessor. At December 31, 2024 and 2023, the Company’s interest, through the Operating Partnership, in the LLCs that own the properties generally entitles it to 38.0% and 37.9% of the aggregate cash distributions from, and the profits and losses of, the LLCs, respectively. The Company determined that the Operating Partnership and the LLCs are variable interest entities (“VIEs”) and that the Company was the primary beneficiary. The assets and liabilities of these VIEs represented substantially all of the Company’s assets and liabilities. "]

["Significant Accounting Policies [Text Block]",{"$cut":{"chars":23456,"head":"2. Significant Accounting Policies Segments At December 31, 2024, the Company had two Basis of Consolidation The accompanying consolidated financial statements of the Company are prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The effect of all intercompany balances has been eliminated. The consolidated financial statements include the accounts of all entities in which the Company has a controlling interest. The ownership interests of other investors in these entities are recorded as non-controlling interests. Use of Estimates The preparation of 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 commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, the useful lives of long-lived assets, review of long-lived assets for impairment and contingent liabilities. Actual results could materially differ from these estimates. Investment in Real Estate Real estate assets held for investment are carried at historical cost and consist of land, buildings and improvements, furniture, fixtures and equipment. Expenditures for ordinary repair and maintenance costs are charged to expense as incurred. Expenditures for improvements, renovations, and replacements of real estate assets are capitalized and depreciated over their estimated useful lives if the expenditures qualify as betterments or the life of the related asset will be substantially extended beyond the original life expectancy. In accordance with ASU 2018-01, \"Business Combinations – Clarifying the Definition of a Business,” the Company evaluates each acquisition of real estate or in-substance real estate to determine if the integrated set of assets and activities acquired meets the definition of a business and needs to be accounted for as a business combination. If either of the following criteria is met, the integrated set of assets and activities acquired would not qualify as a business:\n•\nSubstantially all of the fair value of the gross assets acquired is concentrated in either a single identifiable asset or a group of similar identifiable assets; or\n•\nThe integrated set of assets and activities is lacking, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs (i.e., revenue generated before and after the transaction). An acquired process is considered substantive if:\n•\nThe process includes an organized workforce (or includes an acquired contract that provides access to an organized workforce) that is skilled, knowledgeable and experienced in performing the process;\n•\nThe process cannot be replaced without significant cost, effort or delay; or\n•\nThe process is considered unique or scarce. Generally, the Company expects that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e., land, buildings and related intangible assets) or because the acquisition does not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. Upon acquisition of real estate, the Company assesses the fair values of acquired tangible and intangible assets including land, buildings, tenant improvements, above-market and below-market leases, in-place leases and any other identified intangible assets and assumed liabilities. The Company allocates the purchase price to the assets acquired and liabilities assumed in an asset acquisi"}}]

["Notes to Financial Statements"," "]
["Fair Value Disclosures [Text Block]","6. Fair Value of Financial Instruments GAAP requires the measurement of certain financial instruments at fair value on a recurring basis. In addition, GAAP requires the measure of other financial instruments and balances at fair value on a non-recurring basis (e.g., carrying value of impaired real estate and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories:\n•\nLevel 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities;\n•\nLevel 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and\n•\nLevel 3: prices or valuation techniques where little or no market data is available that require inputs that are both significant to the fair value measurement and unobservable. When available, the Company utilizes quoted market prices from an independent third-party source to determine fair value and classifies such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require the Company to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When the Company determines the market for a financial instrument owned by the Company to be illiquid or when market transactions for similar instruments do not appear orderly, the Company uses several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establishes a fair value by assigning weights to the various valuation sources. Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument. The financial assets and liabilities in the consolidated balance sheets include cash and cash equivalents, restricted cash, receivables, accounts payable and accrued liabilities, security deposits and notes payable. The carrying amount of cash and cash equivalents, restricted cash, receivables, accounts payable and accrued liabilities, and security deposits reported in the consolidated balance sheets approximates fair value due to the short-term nature of these instruments. The fair value of notes payable, which are classified as Level 2, is estimated by discounting the contractual cash flows of each debt instrument to their present value using adjusted market interest rates. The carrying amount and estimated fair value of the notes payable are as follows:\nDecember 31,\nDecember 31,\nCarrying amount (excluding unamortized debt issuance costs) $ 1,275,359 $ 1,219,029\nEstimated fair value $ 1,209,629 $ 1,160,393 The above disclosures regarding fair value of financial instruments are based on pertinent information available as of December 31, 2024 and 2023, respectively. Although the Company is not aware of any factors that would significantly affect the reasonableness of the estimated fair value amounts, such ‐amounts have not been comprehensively revalued for purposes of these financial statements since those dates, and current estimates of fair value may differ significantly from the amounts presented herein.

["Commitments and Contingencies Disclosure [Text Block]","7. Commitments and Contingencies Legal On July 3, 2017, the Supreme Court of the State of New York (the “Court”) ruled in favor of 41 present or former tenants of apartment units at the Company’s buildings located at 50 Murray Street and 53 Park Place in Manhattan, New York (the Tribeca House property), who brought an action (the “Kuzmich” case) against the Company alleging that they were subject to applicable rent stabilization laws with the result that rental payments charged by the Company exceeded amounts permitted under these laws because the buildings were receiving certain tax abatements under Real Property Tax Law (“RPTL”) 421-g. The Court also awarded the plaintiffs- tenants their attorney’s fees and costs. After various court proceedings and discussions from 2018-2022, on March 4, 2022 the court issued a ruling, finalized on May 9, 2022, on the rent overcharges to which the plaintiffs are entitled. While the court ruled that the overcharges to which the plaintiffs are entitled total $1.2 million, the court agreed with the Company’s legal arguments that rendered the overcharge liability lower than it could have been, and therefore the Company did not appeal the ruling. On June 23, 2022, the court ruled that the plaintiffs are entitled to attorneys’ fees incurred through February 28, 2022, in the amount of $0.4 million. The only remaining outstanding issues of which the Company is aware relate to the proper form of rent-stabilized renewal leases for the six plaintiffs who remain as tenants in the building. The parties are seeking judicial intervention to resolve this remaining issue. On July 17, 2023, a hearing was held at which the Judicial Hearing Officer (“JHO”) determined five (5) of the tenant’s lease renewal amounts, term and form. The amount of the lease renewal concerning the sixth plaintiff was made on August 28, 2023. At this time the Company is awaiting the execution and return of all the lease renewals. On June 14, 2024, the Court amended its August 28, 2023 decision, holding that no renewal lease had been entered into by one of the remaining tenants (Navascues) who claimed to have entered into a renewal lease at a preferential rent. On July 20, 2024, Plaintiff filed a notice of appeal from the June 14, 2024 decision. On August 13, 2024, the JHO issued a Determination awarding attorneys’ fees to plaintiffs’ attorneys in the amount of $13 for the Kuzmich matter. On December 31, 2024, the Company filed a notice of appeal from the August 13, 2024 JHO determination. The Company is preparing to comply with the JHO’s Determinations regarding renewal leases, overcharge payments and payment of attorneys fees. The matter is currently pending. On November 18, 2019, the same law firm which filed the Kuzmich case filed a second action involving a separate group of 26 tenants (captioned Crowe et al v 50 Murray Street Acquisition LLC, Supreme Court, New York County, Index No. 161227/19), which action advances essentially the same claims as in Kuzmich. The Company’s deadline to answer or otherwise respond to the complaint in Crowe had been extended to June 30, 2020; on such date, the Company filed its answer to the complaint. Pursuant to the court’s rules, on July 16, 2020, the plaintiffs filed an amended complaint; the sole difference as compared to the initial complaint is that seven new plaintiffs-tenants were added to the caption; there were no substantive changes to the complaint’s allegations. On August 5, 2020, the Company filed its answer to the amended complaint. The case was placed on the court’s calendar and was next scheduled for a discovery conference on November 16, 2022. Counsel for the parties have been engaged in and are continuing settlement discussions. On November 16, 2022, the court held a compliance conference and ordered the plaintiffs to provide rent overcharge calculations in response to proposed calculations previously provided by the Company. On July 12, 2023, the court referred this matter to a JHO to determine the outstanding issues. A hearing before the JHO was held in September 2023. On September 19, 2024 the JHO entered two orders, (1) a June 5, 2024 Determination determining the amount of rent overcharges, if any, due to each of the plaintiffs and the lease renewal amounts, term and form of lease for the plaintiffs remaining in occupancy of four units and (2) a September 3, 2024 Determination sustaining the June 5, 2024 JHO determination which set another plaintiffs rent but reducing the overcharge amount owed to the plaintiff. On October 21, 2024, the Company filed a notice of appeal from the September 3, 2024 JHO order. In addition, on August 13, 2024 the JHO issued a Determination awarding attorneys’ fees to plaintiffs’ attorneys in the amount of $63 for the Crowe matter. This Determination was entered on November 25, 2024. On December 31, 2024, the Company moved to appeal from the August 13, 2024 JHO determination. The Company is preparing to comply with the JHO’s determinations. The matter is currently pending. On March 9, 2021, the same law firm which filed the Kuzmich and Crowe cases filed a third action involving another tenant (captioned Horn v 50Murray Street Acquisition LLC, Supreme Court, New York County, Index No. 152415/21), which action advances the same claims as in Kuzmich and Crowe. The Company filed its answer to the complaint on May 21, 2021. On September 19, 2024 the JHO entered a June 5, 2024 order which determined, among other things, the amount of rent overcharge, the lease renewal amount, term and form of lease for plaintiff Horn. In addition, On August 13, 2024 the JHO issued a Determination awarding attorneys’ fees to plaintiffs’ attorneys in the amount of $18 for the Horn matter. This Determination was entered on November 25, 2024. On December 31, 2024, the Company filed a notice of appeal from the August 13, 2024 JHO determination. The Company is preparing to comply with the JHO’s determinations. As a result of the March 4 and May 9, 2022 decisions which established the probability and ability to reasonably compute amounts owed to tenants for all the cases, the Company recorded a charge for litigation settlement and other of $2.7million in the consolidated statements of operations during the year ended December 31, 2021 comprising rent overcharges, interest and legal costs of plaintiff’s counsel. The Company paid $2.3million to the plaintiffs related to the Kuzmich case during the year ended December 31, 2022 and $0.4 million related to the Crowe case during the nine month period ended September 30, 2023. Based on the JHO determinations made in 2024, the Company accrued an additional $175 for the plaintiffs and $94 for attorney fees. In addition to the above, the Company is subject to certain legal proceedings and claims arising in connection with its business. Management believes, based in part upon consultation with legal counsel, that the ultimate resolution of all such claims will not have a material adverse effect on the Company’s consolidated results of operations, financial position or cash flows. On October 15, 2021, Rodney Sanchez (“Plaintiff”) filed a Class and Collective Action Complaint (the “Complaint”) against and the Company and certain of its affiliates and Clipper Equity LLC (collectively, the “Defendants”) in the United States District Court for the Southern District of New York. The Plaintiff alleged that he was jointly employed by the Defendants and that the Defendants: (a) failed to pay Plaintiff and similarly situated employees overtime in violation of the Fair Labor Standards Act (“FLSA”) and New York Labor Law (“NYLL”); (b) failed to pay Plaintiff and similarly situated employees for training sessions in violation of the FLSA and NYLL; (c) failed to pay Plaintiff and similarly situated employees on a timely basis in violation of NYLL; and (d) failed to provide Plaintiff and similarly situated employees with wage statements and wage notices as required by NYLL. The Company has denied the allegations and intends to defend both the allegations and the class certification action. Given the uncertainty of litigation, the preliminary stage of the case and the legal standards that must be met for, among other things, class certification and success on the merits, the Company cannot estimate the reasonably possible loss or range of loss, if any, that may result from this action and therefore no accrual has been made related to this. The Office of the Attorney General of the State of New York (“OAG”) commenced an investigation concerning the conduct of screening of tenant applicants in the building portfolio in which Clipper Equity and its principals have a management and/or ownership interest. Clipper Equity cooperated with the investigation and, in April 2022, entered into an Assurance of Discontinuance with the OAG to resolve the investigation on behalf of itself and its affiliates, the terms of which have no impact to the Company’s financial position or results of operations. On November 22, 2024, The New York City Department of Citywide Administrative Services issued the results of its audit of the Company’s operating expense escalation charges for the period of June 2014 to December 2018. The audit in a claim by the City for the Company to pay the City $1,152. The Company is evaluating the results of the audit. Based on the results of the audit the Company believes it has adequate reserves to cover this payment. Commitments On June 29, 2023 the Company entered into the Article 11 Agreement. Under the Article 11 agreement, the Company has entered into a Housing Repair and Maintenance Letter Agreement (“HRMLA”) in which the Company has agreed to perform certain capital improvements to Flatbush Gardens over the next three years. The current estimate is that the costs of that work will be an amount up to $27 million. The Company expects those costs to be offset by the savings provided by property tax exemption and enhanced payments for tenants receiving government assistance (See note 1). Through December 31, 2024 the Company spent approximately $9.1 million on capital improvements required under the HRMLA. The Company is obligated to provide parking availability through August 2025 under a lease with a tenant at the 250 Livingston Street property; the current cost to the Company is approximately $205 per year. Concentrations The Company’s properties are located in the Boroughs of Manhattan and Brooklyn in New York City, which exposes the Company to greater economic risks than if it owned a more geographically dispersed portfolio. The breakdown between commercial and residential revenue is as follows:\nCommercial\nResidential\nTotal\nYear ended December 31, 2024 26 % 74 % 100 %\nYear ended December 31, 2023 28 % 72 % 100 % "]

["Segment Reporting Disclosure [Text Block]","9. Segment Reporting The Company is a New York City real estate investment trust that is focused on developing, redeveloping and operating properties in the commercial and residential space. Our Chief Operating Decision Maker (“CODM”), represented by our Co-Chairman and Chief Executive Officer, reviews the results in which the revenue and Income from Operations is divided between the commercial and residential performance. This metric enables the CODM to evaluate how the business is growing, as revenue is the key driver of growth. Additionally, the CODM uses segment income (loss) to allocate resources in the annual budgeting and forecasting process. The CODM considers budget to actual variances when making decisions about allocating capital to each segment. The Company has classified its reporting segments into commercial and residential rental properties. The commercial reporting segment includes the 141 Livingston Street property and portions of the 250 Livingston Street, Tribeca House, Dean Street and Aspen properties.

Contributions to the plans are determined in accordance with the provisions of the negotiated labor contract. The Local 94 International Union of Operating Engineers (“Local 94”) contract is in effect through December 31, 2026. The Local 32BJ Service Employees International Union (“Local 32BJ”) apartment building contract is in effect through April 20, 2026.

Contributions to the unions are not segregated or otherwise restricted to provide benefits only to the Company’s employees. The risks of participating in a multiemployer pension plan differ from those of a single-employer pension plan in the following aspects: (a) assets contributed to a multiemployer pension plan by one employer may be used to provide benefits to employees of other participating employers; (b) if a participating employer stops contributing to the plan, the unfunded obligation of the plan may be borne by the remaining participating employers; and (c) if the Company chooses to stop participating in the multiemployer plan, it may be required to pay the plan an amount based on the unfunded status of the plan, which is referred to as the withdrawal liability.

The ownership interests of other investors in these entities are recorded as non-controlling interests."]
["Use of Estimates, Policy [Policy Text Block]","Use of Estimates The preparation of 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 commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, the useful lives of long-lived assets, review of long-lived assets for impairment and contingent liabilities. Actual results could materially differ from these estimates. "]
["Real Estate, Policy [Policy Text Block]","Investment in Real Estate Real estate assets held for investment are carried at historical cost and consist of land, buildings and improvements, furniture, fixtures and equipment. Expenditures for ordinary repair and maintenance costs are charged to expense as incurred. Expenditures for improvements, renovations, and replacements of real estate assets are capitalized and depreciated over their estimated useful lives if the expenditures qualify as betterments or the life of the related asset will be substantially extended beyond the original life expectancy. In accordance with ASU 2018-01, \"Business Combinations – Clarifying the Definition of a Business,” the Company evaluates each acquisition of real estate or in-substance real estate to determine if the integrated set of assets and activities acquired meets the definition of a business and needs to be accounted for as a business combination. If either of the following criteria is met, the integrated set of assets and activities acquired would not qualify as a business:\n•\nSubstantially all of the fair value of the gross assets acquired is concentrated in either a single identifiable asset or a group of similar identifiable assets; or\n•\nThe integrated set of assets and activities is lacking, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs (i.e., revenue generated before and after the transaction). An acquired process is considered substantive if:\n•\nThe process includes an organized workforce (or includes an acquired contract that provides access to an organized workforce) that is skilled, knowledgeable and experienced in performing the process;\n•\nThe process cannot be replaced without significant cost, effort or delay; or\n•\nThe process is considered unique or scarce. Generally, the Company expects that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e., land, buildings and related intangible assets) or because the acquisition does not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. Upon acquisition of real estate, the Company assesses the fair values of acquired tangible and intangible assets including land, buildings, tenant improvements, above-market and below-market leases, in-place leases and any other identified intangible assets and assumed liabilities. The Company allocates the purchase price to the assets acquired and liabilities assumed in an asset acquisition based on their relative fair values. In estimating fair value of tangible and intangible assets acquired, the Company assesses and considers fair value based on estimated cash flow projections that utilize 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. The Company records acquired above-market and below-market lease values initially based on the present value, using a discount rate which reflects the risks associated with the leases acquired based on the difference 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 renewal options for the below-market leases. Other intangible assets acquired include amounts for in-place lease values and tenant relationship values (if any) that are based on management’s evaluation of the specific characteristics of each tenant’s lease and the Company’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 to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rentals 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. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. A property’s value is impaired 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, a write-down is recorded and measured by the amount of the difference between the carrying value of the asset and the fair value of the asset. In the event that the Company obtains proceeds through an insurance policy due to impairment, the proceeds are offset against the write-down in calculating gain/loss on disposal of assets. Management of the Company does not believe that any of its properties within the portfolio are impaired as of December 31, 2024. For long-lived assets to be disposed of, impairment losses are recognized when the fair value of the assets less estimated cost to sell is less than the carrying value of the assets. Properties classified as real estate held-for-sale generally represent properties that are actively marketed or contracted for sale with closing expected to occur within the next twelve months. Real estate held-for-sale is carried at the lower of cost, net of accumulated depreciation, or fair value less cost to sell, determined on an asset-by-asset basis. Expenditures for ordinary repair and maintenance costs on held-for-sale properties are charged to expense as incurred. Expenditures for improvements, renovations and replacements related to held-for-sale properties are capitalized at cost. Depreciation is not recorded on real estate held-for-sale. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balances of the related intangibles are written off. The tenant improvements and origination costs are amortized to expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:\nBuilding and improvements (in years) 10 – 44\nTenant improvements\nShorter of useful life or lease term\nFurniture, fixtures and equipment (in years) 3 – 15 The capitalized above-market lease values are amortized as a reduction to base rental revenue over the remaining terms 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 value of in-place leases is amortized to expense over the remaining initial terms of the respective leases. "]

Lease costs are being amortized using the straight-line method over the terms of the respective leases. Deferred financing costs represent commitment fees, legal and other third-party costs associated with obtaining financing. These costs are amortized over the term of the financing and are recorded in interest expense in the consolidated statements of operations. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity.

["Revenue [Policy Text Block]","Revenue Recognition As mentioned above under Tenant and Other Receivables and Allowance for Doubtful Accounts the Company records lease income under ASC 842,“Leases” which replaces the guidance under ASC 840. ASC 842 applies to the Company principally as lessor; as a lessee, the Company’s leases are immaterial. The Company has determined that all its leases as lessor are operating leases. The Company has elected to not bifurcate lease and non-lease components under a practical expedient provision. With respect to collectability, the Company has written off all receivables not probable of collection and related deferred rent, and has recorded income for those tenants on a cash basis. When the probability assessment has changed for these receivables, the Company has recognized lease income to the extent of the difference between the lease income that would have been recognized if collectability had always been assessed as probable and the lease income recognized to date. For remaining receivables probable of collection, the Company has recorded a general reserve under ASC 450. For the year ended December 31, 2024 and 2023, the Company charged revenue in the amount of $4,219 and $4,526, respectively, for residential receivables not deemed probable of collection and recognized revenue of $299 and $1,447, respectively, for a reassessment of collectability of residential receivables previously not deemed probable of collection. In accordance with the provisions of ASC 842, rental revenue for commercial leases is recognized on a straight-line basis over the terms of the respective leases. Deferred rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Rental income attributable to residential leases and parking is recognized as earned, which is not materially different from the straight-line basis. Leases entered by residents for apartment units are generally for one-year terms, renewable upon consent of both parties on an annual or monthly basis. Reimbursements for operating expenses due from tenants pursuant to their lease agreements are recognized as revenue in the period the applicable expenses are incurred. These costs generally include real estate taxes, utilities, insurance, common area maintenance costs and other recoverable costs and are recorded as part of commercial rental income in the condensed consolidated statements of operations."]

["Income Tax, Policy [Policy Text Block]","Income Taxes The Company elected to be taxed and to operate in a manner that will allow it to qualify as a REIT under the Code. To qualify as a REIT, the Company is required to distribute dividends equal to at least 90% of the REIT taxable income (computed without regard to the dividends paid deduction and net capital gains) to its stockholders, and meet the various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided the Company qualifies for taxation as a REIT, it is generally not subject to U.S. federal corporate-level income tax on the earnings distributed currently to its stockholders. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to U.S. federal and state income tax on its taxable income at regular corporate tax rates and any applicable alternative minimum tax.

["Derivatives, Policy [Policy Text Block]","Derivative Financial Instruments FASB derivative and hedging guidance establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by FASB guidance, the Company records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecast transactions, are considered cash flow hedges. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (loss) (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in the fair value or cash flows of the derivative hedging instrument with the changes in the fair value or cash flows of the designated hedged item or transaction. For derivatives not designated as hedges, changes in fair value would be recognized in earnings. As of December 31, 2024 and 2023, the Company has no derivatives for which it applies hedge accounting. "]
