Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Preparation	The accompanying interim unaudited consolidated financial statements as of June 30, 2021, and for the three and six months ended June 30, 2021 and 2020, reflect all normal recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the results for such interim periods. The results of operations for the three and six months ended June 30, 2021 and 2020, are not necessarily indicative of the results for the full year. The consolidated audited balance sheet as of December 31, 2020, has been derived from the audited financial statements at that date but does not include all the information and footnotes required by accounting principles generally accepted in the United States ("GAAP"). Accordingly, these unaudited statements should be read in conjunction with the Company's audited financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2020, as amended, filed with the Securities and Exchange Commission ("SEC").
Consolidated Financial Statements and Variable Interest Entities	The consolidated financial statements include the accounts and operations of the Company and its wholly-owned subsidiaries. The Company accounts for its investments in unconsolidated joint ventures under the equity method of accounting. For each venture, the Company evaluated the rights provided to each party in the venture to assess the consolidation of the venture. All investments in unconsolidated joint ventures have sufficient equity at risk to permit the entity to finance its activities without additional subordinated financial support and, as a group, the holders of the equity at risk have power through voting rights to direct the activities of these ventures. As a result, none of these joint ventures are variable interest entities ("VIEs"). Additionally, the Company does not exercise substantial operating control over these entities, and therefore the entities are not consolidated. These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for their share of equity in earnings, cash contributions and distributions. The distributions to each joint venture partner are determined pursuant to the applicable operating agreement and may not be pro-rata to the percentage equity interest each partner has in the applicable venture. The joint venture that owns a property in Yonkers, New York, was determined not to be a VIE but is consolidated because the Company has controlling rights in such entity.
Use of Estimates	The preparation of the financial statements in conformity with GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Actual results could differ from those estimates. Substantially all of the Company's assets are comprised of multi- family real estate assets generally leased to tenants on a one-year basis. Therefore, the Company aggregates real estate assets for reporting purposes and operates in one reportable segment.

As a basis for considering market participant assumptions in fair value measurements, there is a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. Level 1 assets/liabilities are valued based on quoted prices for identical instruments in active markets, Level 2 assets/liabilities are valued based on quoted prices in active markets for similar instruments, on quoted prices in less active or inactive markets, or on other “observable” market inputs, and Level 3 assets/liabilities are valued based significantly on “unobservable” market inputs.

Consolidated Financial Statements and Variable Interest Entities

The consolidated financial statements include the accounts and operations of the Company and its wholly-owned subsidiaries.

The Company accounts for its investments in unconsolidated joint ventures under the equity method of accounting. For each venture, the Company evaluated the rights provided to each party in the venture to assess the consolidation of the venture. All investments in unconsolidated joint ventures have sufficient equity at risk to permit the entity to finance its activities without additional subordinated financial support and, as a group, the holders of the equity at risk have power through voting rights to direct the activities of these ventures. As a result, none of these joint ventures are variable interest entities ("VIEs").

These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for their share of equity in earnings, cash contributions and distributions.
