Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Seven Hills Realty Trust (formerly known as RMR Mortgage Trust), or we, us, our, or the Trust, is a Maryland statutory trust. We were previously registered under the Investment Company Act of 1940, as amended, or the 1940 Act, as a closed-end management investment company. Our investment objective while we operated as a registered investment company was investing in equity securities of real estate companies. On January 5, 2021, the Securities and Exchange Commission, or the SEC, issued an order granting our request to deregister as an investment company under the 1940 Act, or the Deregistration. As a result, the Trust changed its SEC registration to a reporting company under the Securities Exchange Act of 1934, as amended, or the Exchange Act. The issuance of the deregistration order enabled us to proceed with full implementation of our new business mandate to operate as a real estate investment trust, or REIT, that focuses primarily on originating and investing in first mortgage loans secured by middle market and transitional commercial real estate, or CRE, or the Business Change. Merger with Tremont Mortgage Trust On April 26, 2021, we and Tremont Mortgage Trust, or TRMT, entered into an Agreement and Plan of Merger, or the Merger Agreement, pursuant to which, on the terms and subject to the satisfaction or waiver of the conditions thereof, TRMT agreed to merge with and into us, with us continuing as the surviving entity in the merger, or the Merger. The Merger was consummated and became effective at 4:01 p.m., Eastern Time, on September 30, 2021, or the Effective Time. At the Effective Time, the separate existence of TRMT ceased. Pursuant to the terms set forth in the Merger Agreement and the Letter Agreement, dated as of August 26, 2021, by and between us and TRMT, or the Letter Agreement, at the Effective Time, each one (1) issued and outstanding common share of beneficial interest, $0.01 par value per share, of TRMT, or the TRMT Common Shares, was automatically converted into the right to receive 0.516 of one (1) of our common shares of beneficial interest, $0.001 par value per share or, the SEVN Common Shares. No fractional shares of SEVN Common Shares were issued in the Merger, and holders of shares of TRMT Common Shares received cash in lieu of any such fractional shares. Pursuant to the Merger Agreement and the Letter Agreement, at the Effective Time, each outstanding unvested TRMT Common Share awarded under TRMT's equity compensation plan was converted into an award of SEVN Common Shares determined by multiplying the number of unvested TRMT Common Shares subject to such award by 0.516 (rounded down to the nearest whole number). Such award will continue to be subject to the same vesting and other terms and conditions as were in effect immediately prior to the Effective Time. Effective as of the Effective Time, we changed our name to “Seven Hills Realty Trust.” The combined company continues to be managed by our manager and TRMT's manager (until TRMT ceased to exist), Tremont Realty Capital LLC (formerly known as Tremont Realty Advisors LLC), or TRC, or our Manager, and our common shares continue to trade on The Nasdaq Stock Market LLC, or Nasdaq, under the new ticker symbol “SEVN." Upon consummation of the Merger, TRMT's separate management agreement with TRC was terminated and TRC waived its right to receive payment of the termination fee that would otherwise have been payable as a result of that termination. In consideration of this waiver, we agreed that, effective upon consummation of the Merger and the termination of TRMT's management agreement with TRC, certain of the expenses TRC had paid pursuant to such management agreement will be included in the “Termination Fee” under and as defined in our existing management agreement with TRC. The purchase price, based on the closing price of our common shares on September 30, 2021 of $10.31 per share, was approximately $169,150, including the assumption of $128,962 outstanding under TRMT's master repurchase facility and closing costs of approximately $6,160 (excluding closing costs of $5,205 of which was paid by TRMT) and assumed working capital of $10,146. Following the Merger and the other transactions contemplated by the Merger Agreement, we assumed TRMT’s master repurchase facility and the portfolio of 10 loans with an aggregate principal balance of $204,692.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Prior to the Business Change, the Trust was accounted for as an investment company in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 946, Financial Services - Investment Companies , or the Predecessor Basis. Upon the Business Change, we discontinued the application of guidance in ASC Topic 946 and prospectively applied the guidance required under GAAP, applicable to companies that are not investment companies, or the Successor Basis. As a result of these changes, our condensed consolidated financial statements as of and for the three and nine months ended September 30, 2021 are presented separately from our financial statements on the Predecessor Basis, as of and for the periods prior to December 31, 2020. The results of operations from January 1, 2021 through January 4, 2021 were not material to the Trust's condensed consolidated financial statements and have not been presented separately, but they are included in our condensed consolidated statement of operations for the nine months ended September 30, 2021. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of results for the interim periods have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in the accompanying condensed consolidated financial statements include the fair value of financial instruments.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Consolidation. These condensed consolidated financial statements include the accounts of ours and our subsidiaries, all of which are 100% owned directly by us. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. For each investment we make, we evaluate whether consolidation of the borrower's financial statements is required under GAAP. GAAP addresses the application of consolidation principles to an investor with a controlling financial interest. Cash, Cash Equivalents and Restricted Cash. We consider highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted cash primarily consists of deposit proceeds from potential borrowers when originating loans, which may be returned to the applicable borrower upon the closing of the loan, after deducting any transaction costs paid by us for the benefit of such borrower. Loans Held for Investment. Generally, our loans are classified as held for investment based upon our intent and ability to hold them until maturity, or if earlier, repayment. Loans that are held for investment are carried at cost, net of unamortized loan origination, accreted exit fees, unamortized purchase premiums and unaccreted purchase discounts, that are required to be recognized in the carrying value of the loans in accordance with GAAP, unless the loans are deemed to be impaired. Loans that we have a plan to sell or liquidate are held at the lower of cost or fair value less cost to sell. We evaluate each of our loans for impairment at least quarterly by assessing a variety of risk factors in relation to each loan and assigning a risk rating to each loan based on those factors. Factors considered in these evaluations include, but are not limited to, property type, geographic and local market dynamics, physical condition, leasing and tenant profile, projected cash flow, risk of loss, current loan to value ratio, or LTV, debt yield, collateral performance, structure, exit plan and sponsorship. Loans are rated “1” (lower risk) through “5” (impaired/loss likely) as defined below: "1" lower risk—Criteria reflects a sponsor having a strong financial condition and low credit risk and our evaluation of management's experience; collateral performance exceeding performance metrics included in the business plan or credit underwriting; and the property demonstrating stabilized occupancy and/or market rates, resulting in strong current cash flow and net operating income and/or having a very low LTV. "2" average risk—Criteria reflects a sponsor having a stable financial condition and our evaluation of management's experience; collateral performance meeting or exceeding substantially all performance metrics included in the business plan or credit underwriting; and the property demonstrating improved occupancy at market rents, resulting in sufficient current cash flow and/or having a low LTV. "3" acceptable risk—Criteria reflects a sponsor having a history of repaying loans at maturity and meeting its credit obligations and our evaluation of management's experience; collateral performance expected to meet performance metrics included in the business plan or credit underwriting; and the property having a moderate LTV. New loans and loans with a limited history will typically be assigned this rating and will be adjusted to other levels from time to time as appropriate. "4" higher risk—Criteria reflects a sponsor having a history of unresolved missed or late payments, maturity extensions and difficulty timely fulfilling its credit obligations and our evaluation of management's experience; collateral performance failing to meet the business plan or credit underwriting; the existence of a risk of default possibly leading to a loss and/or potential weaknesses that deserve management’s attention; and/or the property having a high LTV. "5" impaired/loss likely—Criteria reflects a very high risk of realizing a principal loss or having incurred a principal loss; a sponsor having a history of default payments, trouble fulfilling its credit obligations, deeds in lieu of foreclosures, and/or bankruptcies; collateral performance is significantly worse than performance metrics included in the business plan; loan covenants or performance milestones having been breached or not attained; timely exit via sale or refinancing being uncertain; and/or the property having a very high LTV. See Note 6 for further information regarding our current loan portfolio’s assessment under our internal risk rating policy. Impairment occurs when it is deemed probable that we will not be able to collect all amounts due under a loan according to its contractual terms. Impairment will then be measured based on the present value of the expected future cash flows discounted at the loan's contractual effective rate and the fair value of any available collateral, net of any costs we expect to incur to realize that value. The determination of this estimated fair value involves judgments and assumptions based on objective and subjective factors. Consideration will be given to various factors, such as business plans, property occupancies, tenant profiles, rental rates, operating expenses and borrowers’ repayment plans, among others, and will require significant judgments regarding certain circumstances, such as guarantees, if any. Upon measurement of an impairment, we will record an allowance to reduce the carrying value of the loan accordingly, and record a corresponding charge to net income in our condensed consolidated statements of operations. As of September 30, 2021, we have not recorded any allowances for losses as we believe it is probable that we will collect all amounts due pursuant to the contractual terms of our loan agreements with borrowers. Fair Value of Financial Instruments. FASB ASC Topic 820-10, Fair Value Measurements and Disclosures , defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands the required disclosure regarding fair value measurements. ASC Topic 820-10 defines fair value as the price that would be received for a financial instrument in a current sale, which assumes an orderly transaction between market participants on the measurement date. We determine the estimated fair value of financial assets and liabilities using the three-tier fair value hierarchy established by GAAP, which prioritizes the inputs used in measuring fair value. GAAP establishes market based or observable inputs as the preferred source of values followed by valuation models using management assumptions in the absence of market inputs. The three levels of inputs that may be used to measure fair value are as follows: Level I—Inputs include quoted prices in active markets for identical assets or liabilities that we have the ability to access. Level II—Inputs include quoted prices in markets that are less active or inactive or for which all significant inputs are observable, either directly or indirectly. Level III—Inputs include unobservable prices and are supported by little or no market activity and are significant to the overall fair value measurement. Loan Deferred Fees. Loan origination and exit fees are reflected in loans held for investment, net, in our condensed consolidated balance sheet and include fees charged to borrowers. These fees are amortized and accreted, respectively, into interest income over the life of the related loans held for investment. At September 30, 2021, we had approximately $1,101 loan origination and exit fees, net of amortization. Deferred Financing Costs. Costs incurred in connection with financings are capitalized and recorded as an offset to the related liability and amortized over the respective financing terms and are recorded in our condensed consolidated statements of operations as a component of interest and related expenses. At September 30, 2021, we had approximately $610 of capitalized financing costs, net of amortization. Net Income Per Common Share. We calculate net income per common share, or EPS, by dividing net income by the weighted average number of common shares outstanding during the period. At September 30, 2021 and December 31, 2020, no warrants, options or other types or classes of securities existed that could be potentially dilutive to our common shares outstanding. Revenue Recognition. Interest income related to our first mortgage loans secured by CRE will generally be accrued based on the coupon rates applied to the outstanding principal balance of such loans. Fees, premiums and discounts, if any, will be amortized or accreted into interest income over the remaining lives of the loans using the effective interest method, as adjusted for any prepayments. If a loan's interest or principal payments are not paid when due and there is uncertainty that such payments will be collected, the loan may be categorized as non-accrual and no interest will be recorded unless it is collected. When all overdue payments are collected and, in our judgment, a loan is likely to remain current, it may be re-categorized as accrual. For loans purchased at a discount, GAAP limits the yield that may be accreted (accretable yield) to the excess of the investor’s estimate of undiscounted expected principal, interest and other cash flows (cash flows expected at acquisition to be collected) over the investor’s initial investment in the loan. GAAP also requires that the excess of contractual cash flows over cash flows expected to be collected (non-accretable difference) not be recognized as an adjustment of yield, loss accrual or valuation allowance. Subsequent increases in cash flows expected to be collected from such loans generally will be recognized prospectively through adjustment of the loan’s yield over its remaining life. Decreases in cash flows expected to be collected will be recorded as an impairment. Securities Transactions and Investment Income. Under the Predecessor Basis, we recorded securities transactions on a trade date basis, dividend income on the ex-dividend date and any non-cash dividends at the fair market value of the securities received. We use the accrual method for recording interest income, including accretion of original issue discount, where applicable, and accretion of discount on short term investments and identified cost basis for realized gains and losses from securities transactions. The difference between cost and fair value for investments we continue to hold is reflected as unrealized gain (loss), and any change in that amount from a prior period is reflected in the accompanying consolidated statement of operations.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update, or ASU, No. 2016-13, Financial Instruments - Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments , which requires that entities use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for credit losses. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. As a smaller reporting company, we expect to adopt ASU No. 2016-13 on January 1, 2023. We are currently assessing the potential impact the adoption of ASU No. 2016-13 will have on our condensed consolidated financial statements. The effect of the adoption of ASU No. 2016-13, if material, will be presented as a cumulative-effect adjustment to equity as of the date of adoption.

Business Combination and Asset Acquisition [Abstract]
Merger with Tremont Mortgage Trust	Merger with Tremont Mortgage Trust As described in Note 1, on September 30, 2021, we completed the Merger, pursuant to which we acquired TRMT's loans held for investment portfolio consisting of 10 loans with an aggregate principal balance of $204,692. The purchase price, based on the closing price of our common shares on September 30, 2021 of $10.31 per share, was $169,150, including the assumption of $128,962 outstanding under TRMT's master repurchase facility and closing costs of approximately $6,160 (excluding closing costs of $5,205 of which was paid by TRMT) and assumed working capital of $10,146. The following table summarizes the consideration transferred and liabilities assumed as a result of the Merger: TRMT common shares outstanding 8,303,629 Multiplied by the exchange ratio 0.516 4,284,673 TRMT fractional shares adjustment (73) SEVN Common Shares issued 4,284,600 Closing price of SEVN Common Shares on September 30, 2021 $ 10.31 Value of consideration transferred $ 44,174 Assumed working capital (10,146) Assumed master repurchase facility, principal balance 128,962 Merger related costs 6,160 Consideration transferred and liabilities assumed $ 169,150 After consideration of applicable factors pursuant to ASC Topic 805, Business Combinations , including the application of a screen test to evaluate if substantially all the fair value of TRMT as the acquired entity is concentrated in a single identifiable asset or group of similar identifiable assets, we have concluded that the Merger qualifies as an asset acquisition under GAAP. Accordingly, SEVN accounted for the Merger as an asset acquisition, with Merger related costs capitalized as a component of the cost of the assets acquired and SEVN treated as the acquirer of TRMT. The assets acquired and liabilities assumed were recorded at their relative fair values and added to our condensed consolidated balance sheet as of September 30, 2021. The fair value of the loans acquired in the Merger exceeded the purchase price of the loans. In accordance with GAAP, a purchase discount of $36,443 is recorded for the difference between the fair value and purchase price of the loans acquired. The purchase discount will be allocated to each acquired TRMT loan and accreted into income over the remaining term of the respective loan. The following table summarizes the purchase price allocation for the Merger: Cash and cash equivalents $ 11,070 Loans held for investment, net 169,150 Accrued interest receivable 603 Prepaid expenses and other assets 31 Total assets 180,854 Accounts payable and other liabilities (901) Master repurchase facility, net (128,962) Due to related persons (657) Net assets acquired 50,334 Assumed working capital (10,146) Assumed master repurchase facility, principal balance 128,962 Consideration transferred and liabilities assumed $ 169,150

In August 2021, we received $19,137 of repayment proceeds from the borrower on our loan that was used to refinance a three-building lab property located in Berkeley, CA, which included outstanding principal of $18,433, a prepayment premium and exit fee of $621, as well as accrued interest and our associated legal expenses of $83. In October 2021, we received $13,130 of repayment proceeds from the borrower on our loan that was used to finance a grocery anchored shopping center in Omaha, NE, which included outstanding principal of $13,053, as well as accrued interest and our associated legal expenses of $76. In October 2021, we originated a first mortgage loan of $24,750 to refinance a multi-tenant office building located in Carlsbad, CA. This loan requires the borrower to pay interest at the floating rate of LIBOR plus a premium of 325 basis points per annum. This floating rate loan includes an initial funding of $23,740 and a future funding allowance of $1,010 for tenant improvements, leasing commissions and capital expenditures and has a three-year initial term with two, one-year extension options, subject to the borrower meeting certain conditions. The tables below detail the property type and geographic location of the properties securing the loans in our portfolio as of September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Property Type Number of Loans Carrying Value Percentage of Value Number of Loans Carrying Value Percentage of Value Office (1) 10 $ 192,994 44 % 2 $ 38,106 41 % Multifamily 4 87,614 20 % — — — % Lab 1 13,384 3 % 2 31,078 34 % Retail 4 59,754 14 % 1 17,029 19 % Industrial (1) 2 60,963 14 % — 5,666 6 % Hotel 1 19,765 5 % — — — % 22 $ 434,474 100 % 5 $ 91,879 100 % (1) Two loan investments secured by mixed use properties consisting of office space and an industrial warehouse in Aurora, IL and Colorado Springs, CO are classified as office for the purpose of counting the number of loans in our portfolio because the majority of the square footage of the properties consists of office space. The carrying value of these loan investments are reflected in office and industrial based on the fair value of the buildings at the time of origination relative to the total fair value of the properties.

The higher the number, the greater the risk level. The following table allocates the carrying value of our loan portfolio at September 30, 2021 and December 31, 2020 based on our internal risk rating policy: September 30, 2021 (Successor Basis) December 31, 2020 (Predecessor Basis) Risk Rating Number of Loans Carrying Value Number of Loans Carrying Value 1 — $ — — $ — 2 2 41,033 — — 3 17 345,584 5 91,879 4 3 47,857 — — 5 — — — — 22 $ 434,474 5 $ 91,879 The weighted average risk rating of our loans by carrying value was 3.0 as of both September 30, 2021 and December 31, 2020. The COVID-19 pandemic has negatively impacted some of our borrowers’ business operations or tenants, particularly in the cases of our retail and hospitality collateral, some of which are the types of properties that have been most negatively impacted by the pandemic. We expect that those negative impacts may continue and may apply to other borrowers and/or their tenants. Further, although economic activity in the United States has improved significantly from the low points during the pandemic to date, certain industries have not recovered to their pre-pandemic positions. Therefore, certain of our borrowers’ business plans will likely take longer to execute than initially expected and certain of our borrowers may be unable to pay their debt service obligations owed and due to us as currently scheduled or at all. As of September 30, 2021, we had three loans representing approximately 11% of the carrying value of our loan portfolio with a loan risk rating of “4” or “higher risk". We did not have any impaired loans or nonaccrual loans as of September 30, 2021 or December 31, 2020. See Note 3 for further information regarding our loan risk ratings.

Debt Disclosure [Abstract]
Debt Agreements	Debt Agreements UBS Master Repurchase Facility On February 18, 2021, one of our wholly owned subsidiaries entered into a master repurchase agreement, or the UBS Master Repurchase Agreement, with UBS for our Master Repurchase Facility, pursuant to which we may sell to UBS, and later repurchase, commercial mortgage loans, or the purchased assets. The expiration date of the UBS Master Repurchase Agreement is February 18, 2024, unless extended or earlier terminated in accordance with the terms of the UBS Master Repurchase Agreement. Pursuant to the UBS Master Repurchase Agreement, we will pay UBS a non-refundable upfront fee that is equal to 0.50% of the applicable tranche amount on each Purchase Date (as each term is defined in the UBS Master Repurchase Agreement). Under our UBS Master Repurchase Facility, the initial purchase price paid by UBS for each purchased asset is up to 75% of the lesser of the market value of the purchased asset and the unpaid principal balance of such purchased asset, subject to UBS’s approval. Upon the repurchase of a purchased asset, we are required to pay UBS the outstanding purchase price of the purchased asset, accrued interest and all accrued and unpaid expenses of UBS relating to such purchased assets. The pricing rate (or interest rate) relating to a purchased asset is equal to one month LIBOR plus a customary premium within a fixed range, determined by the debt yield and property type of the purchased asset’s real estate collateral. UBS has the discretion under our UBS Master Repurchase Agreement to make advancements at margins higher than 75%. The weighted average interest rate for advancements under our UBS Master Repurchase Facility was 2.1% and 2.2% for the three and nine months ended September 30, 2021, respectively. In connection with our UBS Master Repurchase Agreement, we entered into a guaranty, or the UBS Guaranty, which requires us to guarantee 25% of the aggregate repurchase price, and 100% of losses in the event of certain bad acts as well any costs and expenses of UBS related to our UBS Master Repurchase Agreement. The UBS Guaranty also requires us to comply with customary financial covenants, which include the maintenance of a minimum tangible net worth, minimum cash liquidity and a total indebtedness to stockholders' equity ratio. Our UBS Master Repurchase Facility also contains margin maintenance provisions that provide UBS with the right, in certain circumstances related to a Credit Event (as defined in the UBS Master Repurchase Agreement) to redetermine the value of purchased assets. Where a decline in the value of such purchased assets has resulted in a margin deficit, UBS may require us to eliminate any margin deficit through a combination of purchased asset repurchases and cash transfers to UBS subject to UBS’s approval. As of September 30, 2021, we were in compliance with all covenants and other terms under our UBS Master Repurchase Agreement and the UBS Guaranty. Citibank Master Repurchase Facility As previously mentioned in Note 5, as a result of the Merger, we assumed the master repurchase facility with Citibank N.A., or Citibank, or our Citibank Master Repurchase Facility. TRMT had a master repurchase facility pursuant to a Master Repurchase Agreement, dated as of February 9, 2018, between TRMT CB Lender and Citibank N.A., or Citibank, or the Citibank Master Repurchase Agreement, as amended by the First Amendment to the Citibank Master Repurchase Agreement, dated as of November 6, 2018, and the Second Amendment to the Citibank Master Repurchase Agreement, dated as of October 30, 2020. On September 30, 2021, as a result of the Merger, we became party to TRMT's master repurchase facility and entered into a guaranty, or the Citibank Guaranty, in favor of Citibank, pursuant to which, among other things, we replaced TRMT as guarantor of certain obligations of TRMT CB Lender LLC, a wholly owned subsidiary, or TRMT CB Lender, under the Citibank Master Repurchase Agreement. In connection with the closing of the Merger, TRMT CB Lender also entered into a Third Amendment to the Citibank Master Repurchase Agreement and Fifth Amendment to Fee Agreement with Citibank. Pursuant to the Citibank Master Repurchase Agreement, as amended, we may sell to Citibank and later repurchase, floating rate mortgage loans and other related assets. The maximum amount of available advancements under the Citibank Master Repurchase Agreement, as amended, is $213,482, and the expiration date thereof is November 6, 2022, unless extended or earlier terminated in accordance with the terms of the Citibank Master Repurchase Agreement. Under our Citibank Master Repurchase Agreement, the initial purchase price paid by Citibank for each purchased asset is up to 75% of the lesser of the market value of the purchased asset or the unpaid principal balance of such purchased asset, subject to Citibank’s approval. Upon the repurchase of a purchased asset, we are required to pay Citibank the outstanding purchase price of the purchased asset, accrued interest and all accrued and unpaid expenses of Citibank relating to such purchased asset. The price differential (or interest rate) relating to a purchased asset is equal to LIBOR plus a premium of 200 to 250 basis points, determined by the yield of the purchased asset and the property type of the purchased asset’s real estate collateral. Citibank has the discretion under our Citibank Master Repurchase Agreement to make advancements at margins higher than 75% and at premiums of less than 200 basis points. The Citibank Guaranty, which requires us to guarantee 25% of our subsidiary's prompt and complete payment of the purchase price, purchase price differential and any costs and expenses of Citibank related to our Citibank Master Repurchase Agreement. The Citibank Guaranty also requires us to comply with customary financial covenants, which include the maintenance of a minimum tangible net worth, minimum cash liquidity, a total indebtedness to tangible net worth ratio and a minimum interest coverage ratio. These maintenance provisions provide Citibank with the right, in certain circumstances related to a credit event, as defined in our Citibank Master Repurchase Agreement, to re-determine the value of purchased assets. Where a decline in the value of such purchased assets has resulted in a margin deficit, Citibank may require us to eliminate any margin deficit through a combination of purchased asset repurchases and cash transfers to Citibank, subject to Citibank's approval. As of September 30, 2021, we have not received a margin call under our Citibank Master Repurchase Agreement.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments ASC Topic 820, Fair Value Measurements , establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level I) and the lowest priority to unobservable inputs (Level III). A financial asset’s or financial liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. As of September 30, 2021 and December 31, 2020, the carrying values of cash and cash equivalents, restricted cash and accounts payable approximate their fair values due to the short term nature of these financial instruments. At September 30, 2021, the outstanding principal balance under our Master Repurchase Facilities approximated the fair value, as interest was based on floating rates of LIBOR plus a spread, and the spread was consistent with those demanded by the market. We estimate the fair values of our loans held for investment and outstanding principal balances under our Master Repurchase Facilities by using Level III inputs, including discounted cash flow analyses and currently prevailing market terms as of the measurement date, determined by significant unobservable market inputs, which include holding periods, discount rates based on LTV, property types and loan pricing expectations which are corroborated by a comparison with other market participants to determine the appropriate market spread to add to the one month LIBOR (Level III inputs as defined in the fair value hierarchy under GAAP).

The personnel and various services we require to operate our business are provided to us by our Manager, pursuant to a management agreement, which provides for the day to day management of our operations by our Manager, subject to the oversight and direction of our Board of Trustees. Prior Agreements with RMR Advisors Administration Agreement. Prior to its merger with our Manager on January 6, 2021, RMR Advisors LLC, or RMR Advisors, performed administrative functions for us pursuant to an administration agreement with us. RMR Advisors was also a party to a subadministration agreement with State Street Bank and Trust Company, or State Street, to perform substantially all fund accounting and other administrative services for us. Under the administration agreement, RMR Advisors was entitled to reimbursement of the cost of providing administrative services. On January 6, 2021, RMR Advisors merged with and into our Manager, with our Manager being the surviving entity, and our Manager assumed the administration agreement with us and the subadministration agreement with State Street. Each of those agreements was terminated, effective March 16, 2021. We incurred administration service fees of $25 and $73 for the three and nine months ended September 30, 2020, respectively, and $15 for the period from January 1, 2021 to March 16, 2021, all of which related to the subadministration service fees payable by RMR Advisors to State Street and reimbursable by us; we did not incur any additional administration service fees beyond those reimbursable amounts for those periods. Investment Advisory Agreement. Prior to January 5, 2021, RMR Advisors provided us with a continuous investment program, made day to day investment decisions and generally managed our business affairs in accordance with our investment objectives and policies as a registered investment company pursuant to an investment advisory agreement. The investment advisory agreement was terminated on January 5, 2021 with our deregistration as an investment company. Pursuant to the investment advisory agreement, RMR Advisors was compensated at an annual rate of 0.85% of our average daily managed assets. We incurred advisory fees of $599 and $1,851 for the three and nine months ended September 30, 2020, respectively, and for the period from January 1, 2021 to January 5, 2021, we incurred advisory fees of $22 which is included in base management fees in our condensed consolidated statements of operations. We incurred internal audit and compliance costs reimbursable to RMR Advisors of $34 and $102 for the three and nine months ended September 30, 2020, respectively. Current Management Agreement with our Manager Effective January 5, 2021, our Manager provides services to us pursuant to a new management agreement. The annual base management fee payable quarterly (0.375% per quarter) in arrears to TRC by us is equal to 1.5% of our “Equity,” as defined under our management agreement. For purposes of calculating the base management fee for September 30, 2021, we included the net book value of TRMT as acquired by us in the Merger when calculating “Equity.” We recognized base management fees of $731 and $2,145 for the three and nine months ended September 30, 2021, respectively. Pursuant to the terms of our management agreement, no management incentive fees are payable until the first full quarter following the effective date of the management agreement and, thereafter, any management incentive fees would be subject to our Manager earning those fees in accordance with the management agreement adopted by us. We did not incur any management incentive fees for the three and nine months ended September 30, 2021. We are required to pay or to reimburse our Manager and its affiliates for all other costs and expenses of our operations. Some of these overhead, professional and other services are provided by RMR LLC, pursuant to a shared services agreement between our Manager and RMR LLC. These reimbursements include an allocation of the cost of personnel employed by RMR LLC and our share of RMR LLC’s costs for providing our internal audit function. These shared services costs are subject to approval by a majority of our Independent Trustees at least annually. We incurred shared services costs of $385 and $1,049 and payable to our Manager for the three and nine months ended September 30, 2021, respectively. We include these amounts in reimbursement of shared services expenses or general and administrative expenses, as applicable, in our condensed consolidated statements of operations. In connection with the Merger, TRMT terminated its management agreement with TRC, and TRC waived its right to receive payment of the termination fees that would have otherwise resulted due to the Merger. In consideration of this waiver, we agreed that, effective upon consummation of the Merger and the termination of TRMT's management agreement with TRC, certain of the expenses TRC had paid pursuant to its management agreement with TRMT will be included in the “Termination

Weighted Average Common Shares	Weighted Average Common SharesWe calculate basic EPS by dividing net income by the weighted average number of common shares outstanding during the relevant period. We calculate diluted EPS using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common share issuances, and the related impact on earnings, are considered when calculating diluted net income per share. The table below provides a reconciliation of the weighted average number of common shares used in the calculation of basic and diluted net income per share (amounts in thousands): For the Three Months Ended September 30, 2021 For the Nine Months Ended September 30, 2021 Weighted average common shares for basic net income per share 10,263 10,225 Effect of dilutive securities: unvested share awards 1 — Weighted average common shares for diluted net income per share 10,264 10,225

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	Prior to the Business Change, the Trust was accounted for as an investment company in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 946, Financial Services - Investment Companies , or the Predecessor Basis. Upon the Business Change, we discontinued the application of guidance in ASC Topic 946 and prospectively applied the guidance required under GAAP, applicable to companies that are not investment companies, or the Successor Basis. As a result of these changes, our condensed consolidated financial statements as of and for the three and nine months ended September 30, 2021 are presented separately from our financial statements on the Predecessor Basis, as of and for the periods prior to December 31, 2020. The results of operations from January 1, 2021 through January 4, 2021 were not material to the Trust's condensed consolidated financial statements and have not been presented separately, but they are included in our condensed consolidated statement of operations for the nine months ended September 30, 2021. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of results for the interim periods have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in the accompanying condensed consolidated financial statements include the fair value of financial instruments.
Consolidation	Consolidation. These condensed consolidated financial statements include the accounts of ours and our subsidiaries, all of which are 100% owned directly by us. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash. We consider highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted cash primarily consists of deposit proceeds from potential borrowers when originating loans, which may be returned to the applicable borrower upon the closing of the loan, after deducting any transaction costs paid by us for the benefit of such borrower.
Loans Held for Investment	Loans Held for Investment. Generally, our loans are classified as held for investment based upon our intent and ability to hold them until maturity, or if earlier, repayment. Loans that are held for investment are carried at cost, net of unamortized loan origination, accreted exit fees, unamortized purchase premiums and unaccreted purchase discounts, that are required to be recognized in the carrying value of the loans in accordance with GAAP, unless the loans are deemed to be impaired. Loans that we have a plan to sell or liquidate are held at the lower of cost or fair value less cost to sell. We evaluate each of our loans for impairment at least quarterly by assessing a variety of risk factors in relation to each loan and assigning a risk rating to each loan based on those factors. Factors considered in these evaluations include, but are not limited to, property type, geographic and local market dynamics, physical condition, leasing and tenant profile, projected cash flow, risk of loss, current loan to value ratio, or LTV, debt yield, collateral performance, structure, exit plan and sponsorship. Loans are rated “1” (lower risk) through “5” (impaired/loss likely) as defined below: "1" lower risk—Criteria reflects a sponsor having a strong financial condition and low credit risk and our evaluation of management's experience; collateral performance exceeding performance metrics included in the business plan or credit underwriting; and the property demonstrating stabilized occupancy and/or market rates, resulting in strong current cash flow and net operating income and/or having a very low LTV. "2" average risk—Criteria reflects a sponsor having a stable financial condition and our evaluation of management's experience; collateral performance meeting or exceeding substantially all performance metrics included in the business plan or credit underwriting; and the property demonstrating improved occupancy at market rents, resulting in sufficient current cash flow and/or having a low LTV. "3" acceptable risk—Criteria reflects a sponsor having a history of repaying loans at maturity and meeting its credit obligations and our evaluation of management's experience; collateral performance expected to meet performance metrics included in the business plan or credit underwriting; and the property having a moderate LTV. New loans and loans with a limited history will typically be assigned this rating and will be adjusted to other levels from time to time as appropriate. "4" higher risk—Criteria reflects a sponsor having a history of unresolved missed or late payments, maturity extensions and difficulty timely fulfilling its credit obligations and our evaluation of management's experience; collateral performance failing to meet the business plan or credit underwriting; the existence of a risk of default possibly leading to a loss and/or potential weaknesses that deserve management’s attention; and/or the property having a high LTV. "5" impaired/loss likely—Criteria reflects a very high risk of realizing a principal loss or having incurred a principal loss; a sponsor having a history of default payments, trouble fulfilling its credit obligations, deeds in lieu of foreclosures, and/or bankruptcies; collateral performance is significantly worse than performance metrics included in the business plan; loan covenants or performance milestones having been breached or not attained; timely exit via sale or refinancing being uncertain; and/or the property having a very high LTV. See Note 6 for further information regarding our current loan portfolio’s assessment under our internal risk rating policy. Impairment occurs when it is deemed probable that we will not be able to collect all amounts due under a loan according to its contractual terms. Impairment will then be measured based on the present value of the expected future cash flows discounted at the loan's contractual effective rate and the fair value of any available collateral, net of any costs we expect to incur to realize that value. The determination of this estimated fair value involves judgments and assumptions based on objective and subjective factors. Consideration will be given to various factors, such as business plans, property occupancies, tenant profiles, rental rates, operating expenses and borrowers’ repayment plans, among others, and will require significant judgments regarding certain circumstances, such as guarantees, if any. Upon measurement of an impairment, we will record an allowance to reduce the carrying value of the loan accordingly, and record a corresponding charge to net income in our condensed consolidated statements of operations.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. FASB ASC Topic 820-10, Fair Value Measurements and Disclosures , defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands the required disclosure regarding fair value measurements. ASC Topic 820-10 defines fair value as the price that would be received for a financial instrument in a current sale, which assumes an orderly transaction between market participants on the measurement date. We determine the estimated fair value of financial assets and liabilities using the three-tier fair value hierarchy established by GAAP, which prioritizes the inputs used in measuring fair value. GAAP establishes market based or observable inputs as the preferred source of values followed by valuation models using management assumptions in the absence of market inputs. The three levels of inputs that may be used to measure fair value are as follows: Level I—Inputs include quoted prices in active markets for identical assets or liabilities that we have the ability to access. Level II—Inputs include quoted prices in markets that are less active or inactive or for which all significant inputs are observable, either directly or indirectly.
Loan Deferred Fees	Loan Deferred Fees. Loan origination and exit fees are reflected in loans held for investment, net, in our condensed consolidated balance sheet and include fees charged to borrowers. These fees are amortized and accreted, respectively, into interest income over the life of the related loans held for investment.
Deferred Financing Costs	Deferred Financing Costs. Costs incurred in connection with financings are capitalized and recorded as an offset to the related liability and amortized over the respective financing terms and are recorded in our condensed consolidated statements of
Net Income Per Common Share	Net Income Per Common Share. We calculate net income per common share, or EPS, by dividing net income by the weighted average number of common shares outstanding during the period.
Revenue Recognition	Revenue Recognition. Interest income related to our first mortgage loans secured by CRE will generally be accrued based on the coupon rates applied to the outstanding principal balance of such loans. Fees, premiums and discounts, if any, will be amortized or accreted into interest income over the remaining lives of the loans using the effective interest method, as adjusted for any prepayments. If a loan's interest or principal payments are not paid when due and there is uncertainty that such payments will be collected, the loan may be categorized as non-accrual and no interest will be recorded unless it is collected. When all overdue payments are collected and, in our judgment, a loan is likely to remain current, it may be re-categorized as accrual.
Securities Transactions and Investment Income	Securities Transactions and Investment Income. Under the Predecessor Basis, we recorded securities transactions on a trade date basis, dividend income on the ex-dividend date and any non-cash dividends at the fair market value of the securities received. We use the accrual method for recording interest income, including accretion of original issue discount, where applicable, and accretion of discount on short term investments and identified cost basis for realized gains and losses from securities transactions. The difference between cost and fair value for investments we continue to hold is reflected as unrealized gain (loss), and any change in that amount from a prior period is reflected in the accompanying consolidated statement of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update, or ASU, No. 2016-13, Financial Instruments - Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments , which requires that entities use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for credit losses. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. As a smaller reporting company, we expect to adopt ASU No. 2016-13 on January 1, 2023. We are currently assessing the potential impact the adoption of ASU No. 2016-13 will have on our condensed consolidated financial statements. The effect of the adoption of ASU No. 2016-13, if material, will be presented as a cumulative-effect adjustment to equity as of the date of adoption.
