Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies The significant accounting policies of the Company, unless further updated below, are consistent with those disclosed in Note 2 to the Company’s audited consolidated financial statements for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K, filed with the U.S. Securities and Exchange Commission on March 13, 2026. Unaudited Condensed Consolidated Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles in the United States of America (“GAAP”) for complete financial statements. However, in the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation have been included. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2025 and the notes thereto included in the Company’s Annual Report on Form 10-K. The balance sheet information as of December 31, 2025 is derived from audited financial statements, but does not include all disclosures required by GAAP. Results of operations for the three months ended March 31, 2026, are not necessarily indicative of the operating results to be attained in the entire fiscal year or for any subsequent period. Basis of Presentation and Principles of Consolidation The preparation of the unaudited condensed consolidated 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases the use of estimates on (a) various assumptions that consider prior reporting results, (b) projections regarding future operations and (c) general financial market and local and general economic conditions. Actual amounts could differ from those estimates. Significant estimates include the provisions for credit losses and real estate owned. The accompanying unaudited condensed consolidated financial statements of the Company include the accounts of all subsidiaries in which the Company has control over significant operating, financial and investing decisions of the entity. All intercompany accounts and transactions have been eliminated in consolidation. Variable Interest Entities The Company consolidates SN Holdings LLC (“SN Holdings”), a wholly owned subsidiary of the Company established for the sole purpose of acting as the borrower under the revolving credit facility with Needham Bank (as described in Note 9 below), and Sachem Capital Corporation Holdings, LLC ("Holdings"), an indirect, wholly-owned subsidiary of the Company, formed for the sole purpose of acting as the issuer of the $100 million Senior Secured Notes (defined below). SN Holdings and Holdings are variable interest entities (“VIEs”) under the guidance of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810-10, Consolidation, as they were established with insufficient equity at risk and do not have independent operations apart from the Company. The Company has determined that it is the primary beneficiary of SN Holdings and Holdings because it has both (i) the power to direct the activities that most significantly impact their economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be significant to each entity, primarily through its role as the guarantor and through its ability to direct all operational and financing decisions. As of March 31, 2026, SN Holdings had total assets of $93.0 million and total liabilities of $32.2 million, consisting primarily of collateralized mortgage loans and borrowings under the Needham Credit Facility (defined below). The assets of SN Holdings can only be used to settle obligations of SN Holdings and are not available to the Company or its creditors, other than as permitted under the intercompany guaranty and lien release provisions of the Needham Credit Facility. As of March 31, 2026, Holdings had total assets of $195.7 million and total liabilities of $100.5 million, consisting primarily of collateralized mortgage loans and indebtedness evidenced by the Senior Secured Notes. The assets of Holdings can only be used to settle obligations of Holdings and are not available to the Company or its creditors.
