Organization Consolidation And Presentation Of Financial Statements [Abstract]
Business and Organization	(1) Business and Organization TPG RE Finance Trust, Inc. (together with its consolidated subsidiaries, “we,” “us,” “our” or the “Company”) is organized as a holding company and conducts its operations primarily through TPG RE Finance Trust Holdco, LLC (“Holdco”), a Delaware limited liability company that is wholly owned by the Company, and Holdco’s direct and indirect subsidiaries. The Company conducts its operations as a real estate investment trust (“REIT”) for U.S. federal income tax purposes.

The Company’s principal business activity is to directly originate and acquire a diversified portfolio of commercial real estate related assets, consisting primarily of first mortgage loans and senior participation interests in first mortgage loans secured by institutional-quality properties in primary and select secondary markets in the United States.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Basis of Presentation The interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The interim consolidated financial statements include the Company’s accounts, consolidated variable interest entities for which the Company is the primary beneficiary, and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated. The Company believes it has made all necessary adjustments, consisting of only normal recurring items, so that the consolidated financial statements are presented fairly and that estimates made in preparing the consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These interim consolidated financial statements should be read in conjunction with the Company’s Form 10-K filed with the SEC on February 24, 2021. Risks and Uncertainties The coronavirus pandemic (“COVID-19”) resulted in broad challenges globally, has contributed to significant volatility in financial markets and continues to adversely impact global commercial activity. The impact of the outbreak has evolved rapidly around the globe, with many countries taking drastic measures to limit the spread of the virus by instituting quarantines or lockdowns and imposing travel restrictions. Such actions have created significant disruptions to global supply chains, and adversely impacted several industries, including but not limited to, airlines, hospitality, retail and the broader real estate industry. COVID-19 has had a continued and prolonged adverse impact on economic and market conditions and triggered a period of global economic slowdown which has and could continue to have a material adverse effect on the Company’s results and financial condition. Many jurisdictions have re-opened with social distancing measures implemented to curtail the spread of COVID-19, and multiple vaccines have been approved for use in the United States. Although the Company has observed preliminary signs of economic recovery, the Company cannot predict the time required for a meaningful economic recovery to take place. Additional surges in new cases of COVID-19 and mutated strains of the virus have caused additional quarantines and lockdowns, which could delay any economic recovery. The nationwide vaccination program is ongoing and its effectiveness remains uncertain. These factors could further materially and adversely affect the Company’s results and financial condition. The full impact of COVID-19 on the real estate industry, the credit markets and consequently on the Company’s financial condition and results of operations is uncertain and cannot be predicted currently since it depends on several factors beyond the control of the Company including, but not limited to (i) the uncertainty surrounding the severity and duration of the outbreak, including possible recurrences and differing economic and social impacts of the outbreak in various regions of the United States, (ii) the effectiveness of the United States public health response, (iii) the pandemic’s impact on the United States and global economies, (iv) the timing, scope and effectiveness of additional governmental responses to the pandemic, (v) the timing and speed of economic recovery, including the availability of a treatment and effectiveness of vaccines approved for COVID-19, (vi) changes in how certain types of commercial property are used while maintaining social distancing and other techniques intended to control the impact of COVID-19, and (v i i) the negative impact on the Company’s borrowers, real estate values and cost of capital. Reclassifications Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the presentation of the Company’s current period consolidated financial statements. These reclassifications had no effect on the Company’s previously reported net income. Amounts related to Collateralized Loan Obligation Proceeds Held at Trustee were reclassified from in prior period balance sheet to conform to current period presentation. Use of Estimates The preparation of the interim consolidated financial statements in conformity with GAAP requires estimates of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities at the date of the interim consolidated financial statements. Actual results could differ from management’s estimates, and such differences could be material. Significant estimates made in the interim consolidated financial statements include, but are not limited to, the adequacy of our allowance for credit losses and the valuation inputs related thereto and the valuation of financial instruments. Actual amounts and values as of the balance sheet dates may be materially different than the amounts and values reported due to the inherent uncertainty in the estimation process and the limited availability of observable pricing inputs due to market dislocation resulting from the COVID-19 pandemic. Also, future amounts and values could differ materially from those estimates due to changes in values and circumstances after the balance sheet date and the limited availability of observable prices. Principles of Consolidation Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810— Consolidation (“ASC 810”) is a VIE and is consolidated in accordance with GAAP. See Note 6 for details regarding issuance of TRTX 2021-FL4. At each reporting date, the Company reconsiders its primary beneficiary conclusions for all its VIEs to determine if its obligation to absorb losses of, or its rights to receive benefits from, the VIE could potentially be more than insignificant, and will consolidate or not consolidate in accordance with GAAP. See Note 6 for details. Revenue Recognition Interest income on loans is accrued using the interest method based on the contractual terms of the loan, adjusted for expected or realized credit losses, if any. The objective of the interest method is to arrive at periodic interest income, including recognition of fees and costs, at a constant effective yield. Premiums, discounts, and origination fees are amortized or accreted into interest income over the lives of the loans using the interest method, or on a straight-line basis when it approximates the interest method. Extension and modification fees are accreted into income on a straight-line basis, when it approximates the interest method, over the related extension or modification period. Exit fees are accreted into interest income on a straight-line basis, when it approximates the interest method, over the lives of the loans to which they relate unless they can be waived by the Company or a co-lender in connection with a loan refinancing, or if timely collection of principal and interest is doubtful. Prepayment penalties from borrowers are recognized as interest income when received. Certain of the Company’s loan investments have in the past, and may in the future, provide for additional interest based on the borrower’s operating cash flow or appreciation of the underlying collateral. Such amounts are considered contingent interest and are reflected as interest income only upon certainty of collection. Certain of the Company’s loan investments have in the past, and may in the future, provide for the accrual of interest (in part, or in whole) instead of its current payment in cash, with the accrued interest (“PIK interest”) added to the unpaid principal balance of the loan. Such PIK interest is recognized currently as interest income unless the Company concludes eventual collection is unlikely, in which case the PIK interest is written off. All interest accrued but not received for loans placed on non-accrual status is subtracted from interest income at the time the loan is placed on non-accrual status . Based on the Company’s judgment as to the collectability of principal, a loan on non-accrual status is either accounted for on a cash basis, where interest income is recognized only upon receipt of cash for interest payments, or on a cost-recovery basis, where all cash receipts reduce the loan’s carrying value, and interest income is only recorded when such carrying value has been fully recovered. Loans Held for Investment Loans that the Company has the intent and ability to hold for the foreseeable future, or until maturity or repayment, are reported at their outstanding principal balances net of cumulative charge-offs, interest applied to principal (for loans accounted for using the cost recovery method), unamortized premiums, discounts, loan origination fees and costs. Loan origination fees and direct loan origination costs are deferred and recognized in interest income over the estimated life of the loans using the interest method, or on a straight-line basis when it approximates the interest method, adjusted for actual prepayments. Accrued but not yet collected interest is separately reported as accrued interest and fees receivable on the Company’s consolidated balance sheets. When loans are designated as held for investment, the Company’s intent is to hold the loans for the foreseeable future or until maturity or repayment. If subsequent changes in real estate or capital markets occur, the Company may change its intent or its assessment of its ability to hold these loans. Once a determination has been made to sell such loans, they are immediately transferred to loans held for sale and carried at the lower of cost or fair value in accordance with GAAP. Non-Accrual Loans Loans are placed on non-accrual status when the full and timely collection of principal and interest is doubtful, generally when: management determines that the borrower is incapable of, or has ceased efforts toward, curing the cause of a default; the loan becomes 90 days or more past due for principal and interest; or the loan experiences a maturity default. The Company considers an account past due when an obligor fails to pay substantially all (defined as 90%) of the scheduled contractual payments by the due date. In each case, the period of delinquency is based on the number of days payments are contractually past due. A loan may be returned to accrual status if all delinquent principal and interest payments are brought current, and collectability of the remaining principal and interest payments in accordance with the loan agreement is reasonably assured. Loans that in the judgment of the Company’s external manager, TPG RE Finance Trust Management, L.P., a Delaware limited partnership (the “Manager”), are adequately secured and in the process of collection are maintained on accrual status, even if they are 90 days or more past due. Troubled Debt Restructurings A loan is accounted for and reported as a troubled debt restructuring (“TDR”) when, for economic or legal reasons, the Company grants a concession to a borrower experiencing financial difficulty that the Company would not otherwise consider. The Company does not consider a restructuring that includes an insignificant delay in payment as a concession. A delay may be considered insignificant if the payments subject to the delay are insignificant relative to the unpaid principal balance of the loan or collateral value, and the contractual amount due, or the delay in timing of the restructured payment period, is insignificant relative to the frequency of payments, the debt’s original contractual maturity or original expected duration. TDRs that are performing and on accrual status as of the date of the modification remain on accrual status. TDRs that are non-performing as of the date of modification usually remain on non-accrual status until the prospect of future payments in accordance with the modified loan agreement is reasonably assured, which is generally demonstrated when the borrower maintains compliance with the restructured terms for a predetermined period. TDRs with temporary below-market concessions remain designated as a TDR regardless of the accrual or performance status until the loan is paid off. However, if the TDR loan has been modified in a subsequent restructure with market terms and the borrower is not currently experiencing financial difficulty, then the loan may be de-designated as a TDR. Credit Losses Allowance for Credit Losses for Loans Held for Investment On January 1, 2020, the Company adopted Accounting Standard Update (“ASU”) 2016-13, Financial Instruments-Credit Losses, and subsequent amendments, which replaced the incurred loss methodology with an expected loss model known as the Current Expected Credit Loss ("CECL") model. The initial CECL reserve recorded on January 1, 2020 is reflected as a direct charge to retained earnings on the Company’s consolidated statements of changes in equity. Subsequent changes to the CECL reserve are recognized through net income on the Company’s consolidated statements of income (loss) and comprehensive income (loss). The allowance for credit losses measured under the CECL accounting framework represents an estimate of current expected losses for the Company’s existing portfolio of loans held for investment, and is presented as a valuation reserve on the Company’s consolidated balance sheets. Expected credit losses inherent in non-cancelable unfunded loan commitments are accounted for as separate liabilities included in accrued expenses and other liabilities on the consolidated balance sheets. The allowance for credit losses for loans held for investment, as reported in the Company’s consolidated balance sheets, is adjusted by a credit loss benefit (expense), which is reported in earnings in the consolidated statements of income (loss) and comprehensive income (loss) and reduced by the charge-off of loan amounts, net of recoveries and additions related to purchased credit-deteriorated (“PCD”) assets, if relevant. The allowance for credit losses includes a modeled component and an individually-assessed component. The Company has elected to not measure an allowance for credit losses on accrued interest receivables related to all of its loans held for investment because it writes off uncollectable accrued interest receivable in a timely manner pursuant to its non-accrual policy, described above. The Company considers key credit quality indicators in underwriting loans and estimating credit losses, including but not limited to: the capitalization of borrowers and sponsors; the expertise of the borrowers and sponsors in a particular real estate sector and geographic market; collateral type; geographic region; use and occupancy of the property; property market value; loan-to-value (“LTV”) ratio; loan amount and lien position; debt service and coverage ratio; the Company’s risk rating for the same and similar loans; and prior experience with the borrower and sponsor. This information is used to assess the financial and operating capability, experience and profitability of the sponsor/borrower. Ultimate repayment of the Company’s loans is sensitive to interest rate changes, general economic conditions, liquidity, LTV ratio, existence of a liquid investment sales market for commercial properties, and availability of replacement short-term or long-term financing. The loans in the Company’s commercial mortgage loan portfolio are secured by collateral in the following property types: office; multifamily; hotel; mixed-use; condominium; and retail. The Company’s loans are typically collateralized by real estate, or in the case of mezzanine loans, by a partnership interest or similar equity interest in an entity that owns real estate. As a result, the Company regularly evaluates on a loan-by-loan basis, typically no less frequently than quarterly, the extent and impact of any credit deterioration associated with the performance and/or value of the underlying collateral property, and the financial and operating capability of the borrower/sponsor. The Company also evaluates the financial strength of loan guarantors, if any, and the borrower’s competency in managing and operating the property or properties. In addition, the Company considers the overall economic environment, real estate sector, and geographic sub-market in which the borrower operates. Such analyses are completed and reviewed by asset management personnel and evaluated by senior management, who utilize various data sources, including, to the extent available (i) periodic financial data such as property occupancy, tenant profile, rental rates, operating expenses, the borrower’s exit plan, and capitalization and discount rates, (ii) site inspections, (iii) sales and financing comparables, (iv) current credit spreads for refinancing and (v) other market data. Quarterly, the Company evaluates the risk of all loans and assigns a risk rating based on a variety of factors, grouped as follows: (i) loan and credit structure, including the as-is LTV structural features; (ii) quality and stability of real estate value and operating cash flow, including debt yield, property type, dynamics of the geography, property type and local market, physical condition, stability of cash flow, leasing velocity and quality and diversity of tenancy; (iii) performance against underwritten business plan; and (iv) quality, experience and financial condition of sponsor, borrower and guarantor(s). Based on a 5-point scale, the Company’s loans are rated “1” through “5,” from least risk to greatest risk, respectively, which ratings are defined as follows: 1- Outperform—Exceeds performance metrics (for example, technical milestones, occupancy, rents, net operating income) included in original or current credit underwriting and business plan; 2- Meets or Exceeds Expectations—Collateral performance meets or exceeds substantially all performance metrics included in original or current underwriting / business plan; 3- Satisfactory—Collateral performance meets or is on track to meet underwriting; business plan is met or can reasonably be achieved; 4- Underperformance—Collateral performance falls short of original underwriting, material differences exist from business plan, or both; technical milestones have been missed; defaults may exist, or may soon occur absent material improvement; and 5- Default/Possibility of Loss—Collateral performance is significantly worse than underwriting; major variance from business plan; loan covenants or technical milestones have been breached; timely exit from loan via sale or refinancing is questionable; significant risk of principal loss. The Company generally assigns a risk rating of “3” to all loan investments originated during the most recent quarter, except in the case of specific circumstances warranting an exception. The Company’s CECL reserve reflects its estimation of the current and future economic conditions that impact the performance of the commercial real estate assets securing the Company’s loans. These estimations include unemployment rates, interest rates, price indices for commercial property, and other macroeconomic factors that may influence the likelihood and magnitude of potential credit losses for the Company’s loans during their anticipated term. The Company licenses certain macroeconomic financial forecasts to inform its view of the potential future impact that broader economic conditions may have on its loan portfolio’s performance. The forecasts are embedded in the licensed model that the Company uses to estimate its CECL reserve as discussed below . Selection of these economic forecasts requires significant judgment about future events that, while based on the information available to the Company as of the balance sheet date, are ultimately unknowable with certainty, and the actual economic conditions impacting the Company’s portfolio could vary significantly from the estimates the Company made for the periods presented. Due to the COVID-19 pandemic and the dislocation it has caused to the national economy, the commercial real estate markets, and the capital markets, the Company’s ability to estimate key inputs for estimating the allowance for credit losses has been materially and adversely impacted. Key inputs to the estimate include, but are not limited to, LTV, debt service coverage ratio, current and future operating cash flow and performance of collateral properties, the financial strength and liquidity of borrowers and sponsors, capitalization rates and discount rates used to value commercial real estate properties, and market liquidity based on market indices or observable transactions involving the sale or financing of commercial properties. Estimates made by management are necessarily subject to change due to the lack or sharply limited number of observable inputs and uncertainty regarding the duration of the COVID-19 pandemic and its aftereffects. Credit Loss Measurement The amount of allowance for credit losses is influenced by the size of the Company’s loan portfolio, loan asset quality, risk rating, delinquency status, historic loss experience and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The Company employs two methods to estimate credit losses in its loan portfolio: a loss-given-default (“LGD”) model-based approach utilized for substantially all of its loans; and an individually-assessed approach for loans that the Company concludes are ill-suited for use in the model-based approach, or are individually-assessed based on accounting guidance contained in the CECL framework. Once the expected credit loss amount is determined, an allowance for credit losses equal to the calculated expected credit loss is established. Consistent with ASC 326, a loan will be charged off through the allowance for credit losses when it is deemed non-recoverable upon a realization event. This is generally at the time the loan receivable is settled, transferred or exchanged, but non-recoverability may also be concluded by the Company if, in its determination, it is nearly certain that all amounts due will not be collected. This loss shall equal the difference between the cash received, or expected to be received, and the book value of the asset. Factors considered by management in determining if the expected credit loss is permanent or not recoverable include whether management judges the loan to be uncollectible; that is, repayment is deemed to be delayed beyond reasonable time frames, or the loss becomes evident due to the borrower’s lack of assets and liquidity, or the borrower’s sponsor is unwilling or unable to support the loan. This policy is reflective of the investor’s economics as it relates to the ultimate realization of the loan. Allowance for Credit Losses for Loans Held for Investment – Model-Based Approach The model-based approach to measure the allowance for credit losses relates to loans which are not individually-assessed. The Company licenses from Trepp, LLC historical loss information, incorporating loan performance data for over 100,000 commercial real estate loans dating back to 1998, in an analytical model to compute statistical credit loss factors (i.e., probability-of-default and loss-given-default). These statistical credit loss factors are utilized together with individual loan information to estimate the allowance for credit losses. This methodology considers the unique characteristics of the Company’s commercial mortgage loan portfolio and individual assets within the portfolio by considering individual loan risk ratings, delinquency statuses and other credit trends and risk characteristics. Further, the Company incorporates its expectations about the impact of current conditions and reasonable and supportable forecasts on expected future credit losses in deriving its estimate. For the period beyond which the Company is able to make reasonable and supportable forecasts, the Company reverts to unadjusted historical loan loss information based on systematic methodology determined at the input level. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense. Allowance for Credit Losses for Loans Held for Investment – Individually-Assessed Approach In instances where the unique attributes of a loan investment render it ill-suited for the model-based approach because it no longer shares risk characteristics with other loans, or because the Company concludes repayment of the loan is entirely collateral-dependent, or when it is deemed probable that the Company will not be able to collect all amounts due according to the contractual terms of the loan, the Company separately evaluates the amount of expected credit loss using other real estate valuation techniques, considering substantially the same credit factors as utilized in the model-dependent method. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, if repayment is expected solely from the collateral, as determined by management using valuation techniques, frequently discounted cash flow. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than the operation) of the collateral. Unfunded Loan Commitments The Company’s first mortgage loans often contain provisions for future funding conditioned upon the borrower’s execution of its business plan with respect to the underlying collateral property securing the loan. These deferred fundings are typically for base building work, tenant improvement costs and leasing commissions, and occasionally to fund forecasted operating deficits during lease-up, or for interest reserves. These deferred funding commitments may be for specific periods, often require satisfaction by the borrower of conditions precedent, and may contain termination clauses at the option of the borrower or, more rarely, at the Company’s option. The total amount of unfunded commitments does not necessarily represent actual amounts that may be funded in cash in the future, since commitments may expire without being drawn, may be cancelled if certain conditions are not satisfied by the borrower, or borrowers may elect not to borrow some or all of the unused commitment. The Company does not recognize these unfunded loan commitments in its consolidated financial statements. The Company applies its expected credit loss estimates to all future funding commitments that cannot be contractually terminated at the Company’s option. The Company maintains a separate allowance for credit losses from unfunded loan commitments, which is included in accrued expenses and other liabilities on the consolidated balance sheets. The Company estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Company and applies the loss factors used in the allowance for credit loss methodology described above to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan. CRE Debt Securities In the past, the Company acquired CRE debt securities for investment purposes. The Company designated CRE debt securities as available-for-sale (“AFS”) on the acquisition date. CRE debt securities that were classified as AFS were recorded at fair value through other comprehensive income or loss in the Company’s consolidated financial statements. The Company recognized interest income on its CRE debt securities using the interest method, or on a straight-line basis when it approximated the effective interest method, with any premium or discount amortized or accreted into interest income based on the respective outstanding principal balance and corresponding contractual term of the CRE debt security. Accrued but not yet collected interest was separately reported as accrued interest receivable on the Company’s consolidated balance sheets. The Company used a specific identification method when determining the cost of a CRE debt security sold and the amount of unrealized gain or loss reclassified from accumulated other comprehensive income or loss into earnings on the trade date. AFS debt securities in unrealized loss positions were evaluated for impairment related to credit losses at least quarterly. For the purpose of identifying and measuring impairment, any applicable accrued interest was excluded from both the fair value and the amortized cost basis. The Company had elected to write off accrued interest by reversing interest income in the event the accrued interest is deemed uncollectible, generally when the security became 90 days or more past due for principal and interest. The Company first assessed whether it intended to sell the debt security or more likely than not was required to sell the debt security before recovery of its amortized cost basis. If either criterion regarding intent or requirement to sell was met, the debt security’s amortized cost basis was written down to its fair value and the write down was charged against the allowance for credit losses, with any incremental impairment reported in earnings as a loss in the consolidated statements of income (loss) and comprehensive income (loss). Any AFS debt security in an unrealized loss position which the Company d id not intend to sell or was not more likely than not required to sell before recovery of the amortized cost basis wa s assessed for expected credit losses. The performance indicators considered for CRE debt securities relate d to the underlying assets and include d default rates, delinquency rates, percentage of nonperforming assets, debt-to-collateral ratios, third-party guarantees, current levels of subordination, vintage, geographic concentration, analyst reports and forecasts, credit ratings and other market data. In assessing whether a credit loss exists, the Company compare d the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected wa s less than the amortized cost basis for the security, a credit loss exist ed and an allowance for credit losses wa s recorded, limited by the amount the fair value wa s less than amortized cost basis. Declines in fair value of AFS debt securities in an unrealized loss position that were not due to credit losses, such as declines due to changes in market interest rates, were recorded through other comprehensive income. Any impairment that had not been recorded through an allowance for credit losses was recognized in other comprehensive income. Unrealized gains and losses on AFS debt securities presented in the consolidated statements of income (loss) and comprehensive income (loss) included the reversal of unrealized gains and losses at the time gains or losses were realized. Real Estate Owned Real estate acquired as a result of foreclosure or by deed-in-lieu of foreclosure is classified as real estate owned (REO) held for investment until the Company makes a determination to sell. The Company's cost basis in REO is equal to the estimated fair value of the collateral at the date of acquisition, less estimated costs to sell. The estimated fair value of the REO is determined using a discounted cash flow model using inputs that include the highest and best use for each asset, estimated future values based on extensive discussions with local brokers, investors and other market participants, the estimated holding period for the asset, and discount rates that reflect estimated investor return requirements for the risks associated with the expected use of each asset. If the fair value of the REO is lower than the carrying value of the loan, the difference, along with any previously recorded specific CECL reserve, is recorded as a realized loss in the consolidated statements of income (loss) and comprehensive income (loss). Thereafter, events or circumstances may occur that result in a material and sustained decrease in the cash flows generated from the assets, potentially leading to impairment. REO is not

Receivables [Abstract]
Loans Held for Investment and the Allowance for Credit Losses	(3) Loans Held for Investment and the Allowance for Credit Losses The Company originates and acquires first mortgage and mezzanine loans secured by commercial properties. The Company considers these loans to belong to a single portfolio of mortgage loans, and the Company has developed its systematic methodology to determine the allowance for credit losses based on a single portfolio. For purposes of certain disclosures herein, the Company disaggregates this portfolio segment into the following classes of finance receivables: Senior loans; and Subordinated and Mezzanine loans. These loans can potentially subject the Company to concentrations of credit risk as measured by various metrics, including, without limitation, property type collateralizing the loan, loan size, loans to a single sponsor and loans in a single geographic area. The Company’s loans held for investment are accounted for at amortized cost. Interest accrued but not yet collected is separately reported as accrued interest and fees receivable on the Company’s consolidated balance sheets. Amounts within that caption relating to loans held for investment were $14.3 million and $14.0 million as of March 31, 2021 and December 31, 2020. During the three months ended March 31, 2021, the Company originated one mortgage loan, with a total commitment of $45.4 million, an initial unpaid principal balance of $37.5 million, and unfunded commitment at closing of $7.9 million. The following table details overall statistics for the Company’s loan portfolio as of March 31, 2021 (dollars in thousands): March 31, 2021 December 31, 2020 Balance Sheet Portfolio Total Loan Portfolio Balance Sheet Portfolio Total Loan Portfolio Number of loans 58 59 57 58 Floating rate loans 100.0 % 100.0 % 100.0 % 100.0 % Total loan commitment (1) $ 4,983,745 $ 5,115,745 $ 4,943,511 $ 5,075,511 Unpaid principal balance (2) $ 4,587,358 $ 4,587,358 $ 4,524,725 $ 4,524,725 Unfunded loan commitments (3) $ 401,726 $ 401,726 $ 423,487 $ 423,487 Amortized cost $ 4,580,179 $ 4,580,179 $ 4,516,400 $ 4,516,400 Weighted average credit spread (4) 3.2 % 3.2 % 3.2 % 3.2 % Weighted average all-in yield (4) 5.2 % 5.2 % 5.3 % 5.3 % Weighted average term to extended maturity (in years) (5) 2.9 2.9 3.1 3.1 (1) In certain instances, the Company creates structural leverage through the co-origination or non-recourse syndication of a senior loan interest to a third-party. In either case, the senior mortgage loan (i.e., the non-consolidated senior interest) is not included on the Company’s balance sheet. When the Company creates structural leverage through the co-origination or non-recourse syndication of a senior loan interest to a third-party, the Company retains on its balance sheet a mezzanine loan. Total loan commitment encompasses the entire loan portfolio the Company originated, acquired and financed. At March 31, 2021, the Company had one non-consolidated senior interest outstanding of $132.0 million. (2) Unpaid principal balance includes PIK interest of $5.5 million as of March 31, 2021. ( 3 ) Unfunded loan commitments may be funded over the term of each loan, subject in certain cases to an expiration date or a force-funding date, primarily to finance property improvements or lease-related expenditures by the Company’s borrowers, to finance operating deficits during renovation and lease-up, and in limited instances to finance construction. ( 4 ) As of March 31, 2021, all of the Company’s loans were floating rate and were indexed to LIBOR. In addition to credit spread, all-in yield includes the amortization of deferred origination fees, purchase price premium and discount if any, loan origination costs and accrual of both extension and exit fees. Credit spread and all-in yield for the total portfolio assumes the applicable floating benchmark rate as of March 31, 2021 for weighted average calculations. ( 5 ) Extended maturity assumes all extension options are exercised by the borrower; provided, however, that the Company’s loans may be repaid prior to such date. As of March 31, 2021, based on the unpaid principal balance of the Company’s total loan exposure, 23.0% of the Company’s loans were subject to yield maintenance or other prepayment restrictions and 77.0% were open to repayment by the borrower without penalty. The following tables present an overview of the mortgage loan investment portfolio by loan seniority as of March 31, 2021 and December 31, 2020 (dollars in thousands): March 31, 2021 Loans Held for Investment, Net Outstanding Principal Unamortized Premium (Discount), Loan Origination Fees, net Amortized Cost Senior loans $ 4,553,826 $ (7,046 ) $ 4,546,780 Subordinated and mezzanine loans 33,532 (133 ) 33,399 Total $ 4,587,358 $ (7,179 ) $ 4,580,179 Allowance for credit losses (56,641 ) Loans Held for Investment, Net $ 4,523,538 December 31, 2020 Loans Held for Investment, Net Outstanding Principal Unamortized Premium (Discount), Loan Origination Fees, net Amortized Cost Senior loans $ 4,492,209 $ (8,161 ) $ 4,484,048 Subordinated and mezzanine loans 32,516 (164 ) 32,352 Total $ 4,524,725 $ (8,325 ) $ 4,516,400 Allowance for credit losses (59,940 ) Loans Held for Investment, Net $ 4,456,460 For the three months ended March 31, 2021, loan portfolio activity was as follows (dollars in thousands): Carrying Value Balance at December 31, 2020 $ 4,456,460 Additions during the period: Loans originated and acquired 37,091 Additional fundings 30,382 Amortization of origination fees 1,600 Deductions during the period: Collection of principal (5,294 ) Change in allowance for credit losses 3,299 Balance at March 31, 2021 $ 4,523,538 At March 31, 2021 and December 31, 2020, there were no unamortized loan purchase discounts or premiums included in loans held for investment at amortized cost on the consolidated balance sheets. At March 31, 2021 and December 31, 2020, there was $7.2 million and $8.3 million, respectively, of unamortized loan fees and discounts included in loans held for investment, net in the consolidated balance sheets. The Company did not recognize any accelerated fee component of prepayment fees during the three months ended March 31, 2021 and 2020, and recognized $0 million and $0.3 million of such payments, respectively, during the three months ended March 31, 2021 and 2020. Loan Risk Rating As discussed in Note 2, the Company evaluates all of its loans to assign risk ratings on a quarterly basis. Based on a 5-point scale, the Company’s loans are rated “1” through “5,” from least risk to greatest risk, respectively, which ratings are described in Note 2. The Company generally assigns a risk rating of “3” to all loan investments originated during the most recent quarter, except in the case of specific circumstances warranting an exception. The following tables present amortized cost basis by origination year, grouped by risk rating, as of March 31, 2021 (dollars in thousands): March 31, 2021 Amortized Cost by Origination Year 2021 2020 2019 2018 2017 Prior Total Senior loans by internal risk ratings: 1 $ — $ — $ — $ — $ — $ — $ — 2 — — 31,863 337,382 — — 369,245 3 37,098 251,019 1,696,788 1,102,412 255,407 — 3,342,724 4 — — 434,291 46,910 297,382 25,049 803,632 5 — — — 31,179 — — 31,179 Total mortgage loans $ 37,098 $ 251,019 $ 2,162,942 $ 1,517,883 $ 552,789 $ 25,049 $ 4,546,780 Subordinated and mezzanine loans by internal risk ratings: 1 $ — $ — $ — $ — $ — $ — $ — 2 — — — — — — — 3 — — 33,399 — — — 33,399 4 — — — — — — — 5 — — — — — — — Total subordinated and mezzanine loans — — 33,399 — — — 33,399 Total $ 37,098 $ 251,019 $ 2,196,341 $ 1,517,883 $ 552,789 $ 25,049 $ 4,580,179 December 31, 2020 Amortized Cost by Origination Year 2020 2019 2018 2017 2016 Total Senior loans by internal risk ratings: 1 $ — $ — $ — $ — $ — $ — 2 — — 337,738 — — 337,738 3 247,770 1,705,783 1,099,503 255,255 — 3,308,311 4 — 433,334 46,882 301,628 25,049 806,893 5 — — 31,106 — — 31,106 Total mortgage loans $ 247,770 $ 2,139,117 $ 1,515,229 $ 556,883 $ 25,049 $ 4,484,048 Subordinated and mezzanine loans by internal risk ratings: 1 $ — $ — $ — $ — $ — $ — 2 — — — — — — 3 — 32,352 — — — 32,352 4 — — — — — — 5 — — — — — — Total subordinated and mezzanine loans — 32,352 — — — 32,352 Total $ 247,770 $ 2,171,469 $ 1,515,229 $ 556,883 $ 25,049 $ 4,516,400 Loans acquired rather than originated are presented in the table above in the column corresponding to the year of origination, not acquisition.

The weighted average risk ratings of the Company’s loans remain unchanged at 3.1 as of March 31, 2021 and December 31, 2020. During the three months ended March 31, 2021, the Company upgraded one loan from risk category “3” to “2” because the collateral property achieved lease occupancy at rents in excess of underwriting. Allowance for Credit Losses The Company’s reserve developed pursuant to ASC 326 reflects its current estimate of potential credit losses related to its loan portfolio as of March 31, 2021. As part of its allowance for credit losses, the Company maintains a separate allowance for credit losses related to unfunded loan commitments, and this amount is included in accrued expenses and other liabilities on the consolidated balance sheets. For further information on the policies that govern the estimation of the allowances for credit loss levels, see Note 2.

This decline was primarily One loan secured by a retail property was on non-accrual status During the three months ended March 31, 2021, the Company executed five loan modifications with borrowers. As of March 31, 2021, these loans had an aggregate commitment amount of $397.7 million and an aggregate unpaid principal balance of $393.5 million. None of these loan modifications trigger the requirements for accounting as TDRs. The Company’s loan modifications typically temporarily reduce the amount of cash interest collected, permit the accrual of a portion (typically not more than 50%) of the interest due, to be repaid at a later date by the borrower, and/or permit the use of existing reserves to pay interest and other property-level expenses, as well as providing accommodations on conditions for extension, such as waiving debt yield tests, and/or modifying the conditions upon which the underlying borrower may extend the maturity date. In exchange, borrowers and sponsors have made partial principal repayments and/or provided additional cash for payment of interest, operating expenses, and replenishment of interest reserves or capital reserves in amounts and combinations acceptable to the Company. All of the modified loans are performing as of March 31, 2021. As of March 31, 2021, the aggregate number of modified loans outstanding was 11 with an unpaid principal balance of $943.5 million. Total PIK interest of $0.8 million on two loans was deferred and added to the outstanding loan principal during the three months ended March 31, 2021. During the three months ended March 31, 2021, the Company collected 99.4% of interest collections, including PIK interest of 1.2%, compared to 96.7% of interest collections, including PIK interest of 1.7% during the three months ended December 31, 2020. The Company collected 99.1% of interest collections during the three months ended March 31, 2020. The Company did not defer any PIK interest during the three months ended March 31, 2020.

Real Estate Owned Disclosure Of Detailed Components [Abstract]
Real Estate Owned	(4) Real Estate Owned In December 2020, the Company acquired two undeveloped commercially-zoned land parcels on the Las Vegas Strip comprising 27 acres (the “Property”) pursuant to a negotiated deed-in-lieu of foreclosure. At September 30, 2020, this property served as collateral for a first mortgage loan receivable held for investment with an unpaid principal balance of $112.0 million, an independently-assessed credit loss reserve of $12.8 million, and a net carrying value of $99.2 million. On October 9, 2020, the first mortgage loan reached final maturity without repayment or satisfaction of extension conditions, which triggered a maturity default. On December 31, 2020, the Company took ownership of the Property, extinguished the first mortgage loan receivable, and realized a loss of $12.8 million, equal to the previously recorded specific CECL reserve on the first mortgage loan. At March 31, 2021, the Company continued to hold the Property at its estimated fair value at the time of acquisition, net of estimated selling costs, of $99.2 million. The Company’s estimate of the Property’s fair value was determined using a discounted cash flow model and Level 3 inputs, which include estimates of parcel-specific cash flows over a specific holding period, at a discount rate that ranges between 8.0% - 17.5% based on the risk profile of estimated cash flows associated with each respective parcel, and an estimated capitalization rate of 6.25%, where applicable. These inputs are based on the highest and best use for each parcel, estimated future values for the parcels based on extensive discussions with local brokers, investors and other market participants, the estimated holding period for the parcels, and discount rates that reflect estimated investor return requirements for the risks associated with the expected use of each sub-parcel. The Company obtained from a third party a $50.0 million non-recourse first mortgage loan secured by the Property, which is classified as Mortgage Loan Payable on the Company’s consolidated balance sheets. See Note 7 for details of the Mortgage Loan Payable. For the three months ended March 31, 2021, operating revenues from the REO asset were sufficient to cover the operating expenses and were immaterial to the financial results of the Company.

Available-for-Sale Debt Securities	(5) Available-for-Sale Debt Securities As of March 31, 2021 and December 31, 2020, the Company did not own any CRE debt securities. The Company did not acquire any CRE debt securities during the three months ended March 31, 2021. During the three months ended March 31, 2020, the Company sold 11 of its CRE CLO investments for total net proceeds of $151.6 million, recognizing a loss on sale of $36.2 million in Securities Impairments on the consolidated statements of income (loss) and comprehensive income (loss). During the quarter ended March 31, 2020, all but one of the Company’s CRE debt securities portfolio was pledged as collateral under daily mark-to-market secured credit facilities. Fluctuations in the value of the Company’s CRE debt securities portfolio resulted in the Company being required to post cash collateral with the Company’s lenders under these facilities. To mitigate the impact to the Company’s business from these developments, the Company decided to sell substantially all of the Company’s CRE debt securities portfolio. Accordingly, at March 31, 2020, the Company determined it no longer had the intent and ability to retain its investment portfolio of CRE debt securities, wrote down the entire portfolio to its estimated fair value (on securities where amortized cost basis exceeded fair value), and recorded an impairment charge of $167.3 million, which is recognized as expense in Securities Impairments on the consolidated statements of income (loss) and comprehensive income (loss). During the three months ended March 31, 2020, the Company recorded a total loss of $203.5 million recognized as expense in Securities Impairments on the consolidated statements of income (loss) and comprehensive income (loss), offset by a small realized gain.

On March 31, 2021 (the “FL4 Closing Date”), TPG RE Finance Trust CLO Sub-REIT (“Sub-REIT”), a subsidiary of the Company, entered into a collateralized loan obligation (“TRTX 2021-FL4” or “FL4”) through its wholly-owned subsidiaries TRTX 2021-FL4 Issuer, Ltd., an exempted company incorporated in the Cayman Islands with limited liability, as issuer (the “FL4 Issuer”), and TRTX 2021-FL4 Co-Issuer, LLC, a Delaware limited liability company, as co-issuer (the “FL4 Co-Issuer” and together with the FL4 Issuer, the “FL4 Issuers”). On the FL4 Closing Date, FL4 Issuer issued $1.25 billion principal amount of notes (the “FL4 Notes”). The FL4 Co-Issuer co-issued $1.04 billion principal amount of investment grade-rated notes which were purchased by third party investors. Concurrently with the issuance of the FL4 Notes, the FL4 Issuer also issued 112,500 preferred shares, par value $0.001 per share and with an aggregate liquidation preference and notional amount equal to $1,000 per share (the “FL4 Preferred Shares” and, together with the FL4 Notes, the “FL4 Securities”), to TRTX Master Retention Holder, LLC, a Delaware limited liability company and indirect wholly-owned subsidiary of the Company (“FL4 Retention Holder”). Proceeds from the issuance of the FL4 Securities were used to (i) purchase one commercial real estate whole loan (the “FL4 Closing Date Whole Loan”) and 17 pari passu participations in 17 separate commercial real estate whole loans (the “FL4 Closing Date Pari Passu Participations” and, together with the FL4 Closing Date Whole Loan, the “FL4 Closing Date Collateral Interests”), (ii) fund an account (the “FL4 Ramp-Up Account”) in an amount of approximately $ 308.9 million to be used to purchase eligible collateral interests during a ramp-up period of approximately six months following the Closing Date (the “FL4 Ramp-Up Collateral Interests,” and, together with the FL4 Whole Loans, the “FL4 Initial Collateral Interests”) and (iii) to distribute to the Company $ 104.8 million of cash for investment or other corporate uses. T he FL4 Closing Date Collateral Interests were purchased by the FL4 Issuer from the FL4 Seller, a wholly-owned subsidiary of the Company and an affiliate of the FL4 Issuers. The FL4 Ramp-Up Account represents cash held at the trustee and is included in Collateralized Loan Obligation Proceeds Held at Trustee on the Company’s consolidated balance sheets. The FL4 Ramp-Up Account is available to purchase eligible collateral interests from the Company during the six-month ramp-up period. In the event the FL4 Ramp-Up Account is not fully utilized within six months of the FL4 Closing Date, amounts up to and including $5.0 million shall be deposited into the FL4 reinvestment account. Any amounts in excess of $5.0 million shall be applied to retire FL4 bonds payable on the first payment date after the ramp-up period in accordance with the priority of payments. TRTX 2021-FL4 permits the Company, during the 24 months after closing, to contribute eligible new loans or participation interests (the “FL4 Additional Interests”) in loans to TRTX 2021-FL4 in exchange for cash, which provides additional liquidity to the Company to originate new loan investments as underlying loans repay. FL4 Closing Date Collateral Interests represented 20.5% of the aggregate unpaid principal balance of the Company’s loan investment portfolio and had an aggregate principal balance of approximately $0.9 billion as of March 31, 2021, and $308.9 million in the FL4 Ramp-Up Account to be used for purchase of certain other collateral interests during the ramp-up period. In connection with TRTX 2021-FL4, the Company incurred $8.3 million of issuance costs which are amortized on an effective yield basis over the expected life of the investment-grade notes issued based upon the expected repayment behavior of the loans collateralizing the notes after giving effect to the reinvestment period, both as of the FL4 Closing Date. As of March 31, 2021, the Company’s unamortized issuance costs related to TRTX 2021-FL4 were $8.3 million. Interest expense on the outstanding FL4 Notes is payable monthly. For the three months ended March 31, 2021, interest expense on the outstanding FL4 Notes (excluding amortization of deferred financing costs) of $0.04 million is included in the Company’s consolidated statements of income (loss) and comprehensive income (loss). On October 25, 2019 (the “FL3 Closing Date”), Sub-REIT entered into a collateralized loan obligation (“TRTX 2019-FL3” or “FL3”). TRTX 2019-FL3 provides for reinvestment, during the 24 months after closing of FL3, whereby eligible new loans or participation interests (the “FL3 Additional Interests”) in loans may be contributed to TRTX 2019-FL3 in exchange for cash, which provides liquidity to the Company to originate new loan investments as underlying loans repay. For the three months ended March 31, 2021, the Company did not utilize the reinvestment feature. For the three months ended March 31, 2020, the Company utilized the reinvestment feature four times, contributing $157.3 million of new loans or participating interests in loans, and receiving $47.3 million of cash, after the repayment of $110.0 million of existing borrowings, including accrued interest. As of March 31, 2021 FL3 Mortgage Assets represented 26.8% of the aggregate unpaid principal balance of the Company’s loan investment portfolio and had an aggregate principal balance of approximately $1.2 billion. At March 31, 2021, TRTX 2019-FL3 had $1.2 million of cash available to acquire eligible assets which is included in Collateralized Loan Obligation Proceeds Held at Trustee on the Company’s consolidated balance sheets. In connection with TRTX 2019-FL3, the Company incurred $7.8 million of issuance costs which are amortized on an effective yield basis over the expected life of the investment-grade notes issued based upon the expected repayment behavior of the loans collateralizing the notes after giving effect to the reinvestment period, both as of the FL3 Closing Date. As of March 31, 2021, the Company’s unamortized issuance costs related to TRTX 2019-FL3 were $4.5 million. Interest expense on the outstanding FL3 Notes is payable monthly. For the three months ended March 31, 2021, interest expense on the outstanding FL3 Notes (excluding amortization of deferred financing costs) of $3.8 million On November 29, 2018 (the “FL2 Closing Date”), Sub-REIT entered into a collateralized loan obligation (“TRTX 2018-FL2” or “FL2”). TRTX 2018-FL2 provides for reinvestment, during the 24 months after closing of FL2, whereby eligible new loans or participation interests in loans may be contributed to TRTX 2018-FL2 in exchange for cash, which provide d additional liquidity to the Company to originate new loan investments as underlying loans repay . The reinvestment period for TRTX 2018-FL2 ended on December 11, 2020. At March 31, 2021, TRTX 2018-FL2 had no cash available to acquire eligible assets. For the three months ended March 31, 2020, the Company utilized the reinvestment feature three times, contributing $ 74.3 million of new loans or participation interests in loans, and receiving net cash proceeds of $ 45.1 million, after the repayment of $ 29.2 million of existing borrowings, including accrued interest. As of March 31, 2021, FL2 Mortgage Assets represented 21.7% of the aggregate unpaid principal balance of the Company’s loan investment portfolio and had an aggregate principal balance of approximately $1.0 billion In connection with TRTX 2018-FL2, the Company incurred $8.7 million of issuance costs which are amortized on an effective yield basis over the expected life of the investment-grade notes (the “FL2 Notes”) issued based upon the expected repayment behavior of the loans collateralizing the notes and the reinvestment period, both as of the FL2 Closing Date. As of March 31, 2021, the Company’s unamortized issuance costs related to TRTX 2018-FL2 were $3.2 million. Interest expense on the outstanding FL2 Notes is payable monthly. For the three months ended March 31, 2021, interest expense on the outstanding FL2 Notes (excluding amortization of deferred financing costs) of $3.1 million is included in the Company’s consolidated statements of income (loss) and comprehensive income (loss). In accordance with ASC 810, the Company evaluated the key attributes of the issuers of the FL4 Notes (the “FL4 Issuers”), FL3 Notes (the “FL3 Issuers”) and the issuers of the FL2 Notes (the “FL2 Issuers”) to determine if they were VIEs and, if so, whether the Company was the primary beneficiary of their operating activities. This analysis caused the Company to conclude that the FL4 Issuers, FL3 Issuers and the FL2 Issuers were VIEs and that the Company was the primary beneficiary. The Company is the primary beneficiary because it has the ability to control the most significant activities of the FL4 Issuers, FL3 Issuers and the FL2 Issuers, the obligation to absorb losses to the extent of its equity investments, and the right to receive benefits, that could potentially be significant to these entities. Accordingly, the Company consolidates the FL4 Issuers, FL3 Issuers and the FL2 Issuers. The Company’s total assets and total liabilities as of March 31, 2021 and December 31, 2020 included the following VIE assets and liabilities of TRTX 2021-FL4, TRTX 2019-FL3 and TRTX 2018-FL2 (dollars in thousands): March 31, 2021 December 31, 2020 ASSETS Cash and Cash Equivalents $ 47,383 $ 78,350 Collateralized Loan Obligation Proceeds Held at Trustee 310,070 174 Accounts Receivable from Servicer/Trustee 202 — Accrued Interest Receivable 1,029 740 Loans Held for Investment 3,141,155 2,199,666 Total Assets $ 3,499,839 $ 2,278,930 LIABILITIES Accrued Interest Payable $ 1,395 $ 1,311 Accrued Expenses 988 630 Collateralized Loan Obligations 2,851,709 1,825,569 Payable to Affiliates 13,986 14,016 Total Liabilities $ 2,868,078 $ 1,841,526 The following tables outline TRTX 2021-FL4, TRTX 2019-FL3 and TRTX 2018-FL2 loan collateral and borrowings under the TRTX 2021-FL4, TRTX 2019-FL3 and TRTX 2018-FL2 collateralized loan obligations as of March 31, 2021 and December 31, 2020 (dollars in thousands): March 31, 2021 Collateral (loan investments) Debt (notes issued) Outstanding Principal Carrying Value Face Value Carrying Value $ 3,141,155 $ 3,141,155 $ 2,868,047 $ 2,851,709 December 31, 2020 Collateral (loan investments) Debt (notes issued) Outstanding Principal Carrying Value Face Value Carrying Value $ 2,230,276 $ 2,230,276 $ 1,834,760 $ 1,825,568 Assets held by the FL4 Issuers, FL3 Issuers and the FL2 Issuers are restricted and can only be used to settle obligations of the related VIE.

Secured Credit Agreements and Mortgage Loan Payable	(7) Secured Credit Agreements and Mortgage Loan Payable At March 31, 2021 and December 31, 2020, the Company had secured credit facilities and a mortgage loan payable, all of which were used to finance certain of the Company’s loan investments. These financing arrangements bear interest at rates equal to LIBOR plus a credit spread negotiated between the Company and each lender, often a separate credit spread for each pledge of collateral, which is primarily based on property type and advance rate against the unpaid principal balance of the pledged loan. Except for the mortgage loan payable, these borrowing arrangements contain defined mark-to-market provisions that permit our lenders to issue margin calls to the Company in the event that the collateral properties underlying the Company’s loans pledged to the Company’s lenders experience a non-temporary decline in value (“credit marks”) due to reasons other than capital markets events that result in changing credit spreads for similar borrowing obligations. In connection with one of these borrowing arrangements, the lender is also permitted to issue margin calls to the Company in the event the lender determines capital markets events have caused credit spreads to change for similar borrowing obligations (“spread marks”).

(3) The Company extended its existing secured facility with Morgan Stanley on May 3, 2021 to a new initial maturity date of May 4, 2022. The Company’s secured credit facilities contain defined mark-to-market provisions that permit the lenders to issue margin calls in the event that the collateral properties underlying the Company’s loans pledged to its lenders experience a non-temporary decline in value or net cash flow (“credit marks”) due to reasons other than capital markets events that result in changing credit spreads for similar borrowing obligations. In connection with one of these borrowing arrangements, the lender is also permitted to issue margin calls to the Company in the event the lender determines capital markets events have caused credit spreads to change for similar borrowing obligations (“spread marks”). Furthermore, in connection with one of these borrowing arrangements, the lender has the right to re-margin the secured credit facility based solely on appraised loan-to-values in the third year of the facility.

Credit spreads vary depending upon the collateral type, advance rate and other factors. Assets pledged at March 31, 2021 and December 31, 2020 consisted of 37 and 55 mortgage loans, or participation interests therein, respectively. Under these secured credit agreements, the Company transfers all of its rights, title and interest in the loans to the repurchase counterparty in exchange for cash, and simultaneously agrees to reacquire the asset at a future date for an amount equal to the cash exchanged plus an interest factor. The repurchase counterparty (lender) collects all principal and interest on related loans and remits to the Company the net amount after the lender collects its interest and other fees. For the seventh credit facility, which is a mortgage warehouse facility, the lender receives a security interest (pledge) in the loans financed under the arrangement. The secured credit facilities used to finance loan investments are 25% recourse to Holdco. Under each of the Company’s secured credit facilities, including the mortgage warehouse facility, the Company is required to post margin for changes in conditions to specific loans that serve as collateral for those secured credit facilities. The lender’s margin amount is in all but one instance limited to collateral-specific credit marks based on other-than-temporary declines in the value of the properties securing the underlying loan collateral. Market value determinations and redeterminations may be made by the repurchase lender in its sole discretion subject to certain specified parameters. In the case of assets that serve as collateral under the Company’s secured credit facilities secured by loans, these considerations include credit-based factors (which are generally based on factors other than those related to the capital markets). In only one instance do the considerations include changes in observable credit spreads in the market for these assets. These factors are described in the immediately preceding table.

The secured credit agreement has an accordion feature that permits the Company to increase the commitment amount in increments of $50.0 million up to a maximum of $500.0 million. Financial Covenants The Company’s financial covenants and guarantees for outstanding borrowings related to our secured credit agreements and secured revolving credit agreements require Holdco to maintain compliance with the following financial covenants (among others), which were revised on May 28, 2020 as follows: Financial Covenant Current Prior to May 28, 2020 Cash Liquidity Minimum cash liquidity of no less than the greater of: $10.0 million; and 5.0% of Holdco’s recourse indebtedness Minimum cash liquidity of no less than the greater of: $10.0 million; and 5.0% of Holdco’s recourse indebtedness Tangible Net Worth $1.1 billion as of April 1, 2020, plus 75% of future equity issuances thereafter Minimum tangible net worth of at least 75% of the net cash proceeds of all prior equity issuances made by Holdco or the Company, plus 75% of the net cash proceeds of all subsequent equity issuances made by Holdco or the Company Debt-to-Equity Debt-to-Equity ratio not to exceed 3.5 to 1.0 with "equity" and "equity adjustment" as defined below Debt-to-Equity ratio not to exceed 3.5 to 1.0 Interest Coverage Minimum interest coverage ratio of no less than 1.5 to 1.0 Minimum interest coverage ratio of no less than 1.5 to 1.0 The amendments as of May 28, 2020 revised the definition of tangible net worth such that the baseline amount for testing was reset as of April 1, 2020 to $1.1 billion plus 75% of future equity issuances after April 1, 2020. The definition of equity for purposes of calculating the debt-to-equity covenant was revised to include: common equity; preferred equity; and an adjustment equal to the sum of the Current Expected Credit Loss reserve, write-downs, impairments or realized losses recorded against the value of any assets of Holdco or its subsidiaries from and after April 1, 2020; provided, however, that the equity adjustment may not exceed the amount of (a) Holdco’s total equity less (b) the product of Holdco’s total indebtedness multiplied by 25%. Financial Covenant relating to the Series B Preferred Stock For long as the Series B Preferred Stock is outstanding, the Company is required to maintain a debt-to-equity ratio not greater than 3.0 to 1.0. For the purpose of determining this ratio, the aggregate liquidation preference of the outstanding shares of Series B Preferred Stock is excluded from the calculation of total indebtedness of the Company and its subsidiaries, and is included in the calculation of total equity. Covenant Compliance The Company was in compliance with all financial covenants to the extent that balances were outstanding as of March 31, 2021 and December 31, 2020. Negative impacts on the Company’s business caused by COVID-19 have and may continue to make it more difficult to meet or satisfy these covenants, and there can be no assurance that the Company will remain in compliance with these covenants in the future. Mortgage Loan Payable The Company through a special purpose entity subsidiary is a borrower under a $50.0 million mortgage loan secured by a first deed of trust against the Property. Refer to Note 4 for additional information. The first mortgage loan was provided by an institutional lender, has an initial maturity date of December 15, 2021, and includes an option to extend the maturity for 12 months subject to the satisfaction of customary extension conditions, including (i) the purchase of a new interest rate cap for the extension term, (ii) replenishment of the interest reserve with an amount equal to 12 months of debt service, (iii) payment of a 0.25% extension fee on the outstanding principal balance, and (iv) no event of default. The first mortgage loan permits partial releases of collateral in exchange for payment of a minimum release price equal to the greater of 100% of net sales proceeds (after reasonable transaction expenses) or 115% of the allocated loan amount. The loan bears interest at a rate of LIBOR plus 4.50% subject to a LIBOR interest rate floor of 0.50% and a rate cap of 0.50%. The Company has posted cash of $2.4 million to pre-fund interest payments due under the note during its initial term. At March 31, 2021, the remaining reserve balance was $2.0 million.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(9) Fair Value Measurements The Company’s consolidated balance sheet includes Level I fair value measurements related to cash equivalents, restricted cash, accounts receivable, and accrued liabilities. At March 31, 2021, the Company had $291.8 million invested in money market funds with original maturities of less than 90 days. The carrying values of these financial assets and liabilities are reasonable estimates of fair value because of the short-term maturities of these instruments. The consolidated balance sheet also includes loans held for investment, the assets and liabilities of TRTX 2018-FL2, TRTX 2019-FL3 and TRTX 2021-FL4 (as of March 31, 2021), and secured debt agreements that are considered Level III fair value measurements that are not measured at fair value on a recurring basis but are subject to fair value adjustments utilizing the fair value of the underlying collateral when there is evidence of impairment and when the loan is dependent solely on the collateral for payment of principal and interest. The following tables provide information about the fair value of the Company’s financial assets and liabilities on the Company’s consolidated balance sheets as of March 31, 2021 and December 31, 2020 (dollars in thousands): March 31, 2021 Fair Value Carrying Value Level I Level II Level III Financial Assets Loans Held for Investment $ 4,523,538 $ — $ — $ 4,571,875 Financial Liabilities Collateralized Loan Obligations 2,851,709 — — 2,855,190 Secured Financing Agreements 854,998 — — 848,765 Mortgage Loan Payable 49,217 — — 49,217 December 31, 2020 Fair Value Carrying Value Level I Level II Level III Financial Assets Loans Held for Investment $ 4,456,460 $ — $ — $ 4,472,984 Financial Liabilities Collateralized Loan Obligations 1,825,568 — — 1,834,760 Secured Financing Agreements 1,514,028 — — 1,532,910 Mortgage Loan Payable 49,147 — — 49,147 At March 31, 2021 and December 31, 2020, the estimated fair value of Loans Held for Investment was $4.6 billion and $4.5 billion, respectively, which approximated carrying value.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	(10) Income Taxes The Company indirectly owns 100% of the equity of multiple taxable REIT subsidiaries (collectively “TRSs”). TRSs are subject to applicable U.S. federal, state, local and foreign income tax on their taxable income. In addition, as a REIT, the Company also may be subject to a 100% excise tax on certain transactions between it and its TRSs that are not conducted on an arm’s-length basis. The Company files income tax returns in the United States federal jurisdiction as well as various state and local jurisdictions. The filings are subject to normal reviews by tax authorities until the related statute of limitations expires. The years open to examination generally range from 2017 to present. ASC 740 also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company has analyzed its various federal and state filing positions and believes that its income tax filing positions and deductions are well documented and supported. As of March 31, 2021 and December 31, 2020, based on the Company’s evaluation, the Company did not have any material uncertain income tax positions. The Company’s policy is to classify interest and penalties associated with underpayment of U.S. federal and state income taxes, if any, as a component of general and administrative expense on its consolidated statements of income (loss) and comprehensive income (loss). For the three months ended March 31, 2021, the Company did not have interest or penalties associated with the underpayment of any income taxes. The Company owns, through a tax partnership (“Parent LLC”), 100% of the common equity in Sub-REIT, which qualifies as a REIT for U.S. federal income tax purposes and is a separate taxpayer from both the Company and Parent LLC. Parent LLC is owned by the Company both directly and through a TRS. The Company, through Sub-REIT, issues CRE CLO liabilities (“CLOs”) to finance on a non-recourse, non-mark-to-market basis a large proportion of its loan investment portfolio. Due to unusually low LIBOR rates beginning in March 2020 coupled with the benefit of LIBOR floors relating to the various loans and participation interests pledged to Sub-REIT’s CLOs, certain of Sub-REIT‘s CLOs currently generate excess inclusion income (“EII”), which is treated as unrelated business taxable income (“UBTI”). Published IRS guidance requires that Sub-REIT allocate its EII in accordance with its dividends paid. Accordingly, EII generated by Sub-REIT‘s CLOs is allocated to Parent LLC. Pursuant to the Parent LLC operating agreement, any EII allocated from Sub-REIT to Parent LLC is allocated further to the TRS. Consequently, no EII is allocated to the Company and, as a result, the Company’s shareholders will not be allocated any EII or UBTI by the Company. The tax liability borne by the TRS on the EII is at the highest U.S. federal corporate tax rate (currently 21%). This tax liability is included in the consolidated statements of income (loss) and comprehensive income (loss) and balance sheets of the Company. For the three months ended March 31, 2021 and 2020, the Company incurred no federal, state or local tax relating to its TRSs. For the three months ended March 31, 2021 and 2020, the Company recognized $0.9 million and $0.1 million, respectively, of federal, state and local tax expense. At March 31, 2021 and 2020, the Company’s effective tax rate was 2.8% and 0.5%, respectively. As of December 31, 2020, no deferred income tax assets or liabilities were recorded for the operating activities of the Company’s TRSs. From March 23, 2020 through April 2020, the Company sold all its CRE debt securities with an aggregate face value of $969.8 million, generating gross sales proceeds of $766.4 million. The Company recorded losses from these sales of $203.4 million recognized as expense in Securities Impairments on the consolidated statements of income (loss) and comprehensive income (loss), which are expected to be available to offset any capital gains of the Company in 2020 and, to the extent those capital losses exceed the Company’s capital gains for 2020, such losses would be available to be carried forward to offset capital gains in future years. The Company does not expect these losses to reduce the amount that the Company will be required to distribute under the requirement that the Company distribute to the Company’s stockholders at least 90% of the Company’s REIT taxable income (computed without regard to the deduction for dividends paid and excluding net capital gain) each year in order to continue to qualify as a REIT.

Related Party Transactions [Abstract]
Related Party Transactions	(11) Related Party Transactions Management Agreement The Company is externally managed and advised by the Manager pursuant to the terms of a management agreement between the Company and the Manager (as amended, the “Management Agreement”). Pursuant to the Management Agreement, the Company pays the Manager a base management fee equal to the greater of $250,000 per annum ($62,500 per quarter) or 1.50% per annum (0.375% per quarter) of the Company’s “Equity” as defined in the Management Agreement. Proceeds from the issuance of Series B Preferred Stock is included in the Company’s Equity for purposes of determining the base management fee. The base management fee is payable in cash, quarterly in arrears. The Manager is also entitled to incentive compensation which is calculated and payable in cash with respect to each calendar quarter in arrears in an amount, not less than zero, equal to the difference between: (1) the product of (a) 20% and (b) the difference between (i) the Company’s Core Earnings for the most recent 12-month period, including the calendar quarter (or part thereof) for which the calculation of incentive compensation is being made (the “applicable period”), and (ii) the product of (A) the Company’s Equity in the most recent 12-month period, including the applicable period, and (B) 7% per annum; and (2) the sum of any incentive compensation paid to the Manager with respect to the first three calendar quarters of the most recent 12-month period. No incentive compensation is payable to the Manager with respect to any calendar quarter unless Core Earnings for the 12 most recently completed calendar quarters is greater than zero. For purposes of calculating the Manager’s incentive compensation, the Management Agreement, as amended, specifies that equity securities of the Company or any of the Company’s subsidiaries that are entitled to a specified periodic distribution or have other debt characteristics will not constitute equity securities and will not be included in “Equity” for the purpose of calculating incentive compensation. Instead, the aggregate distribution amount that accrues to such equity securities during the calendar quarter of such calculation will be subtracted from Core Earnings, before incentive compensation for purposes of calculating incentive compensation, unless such distribution is otherwise excluded from Core Earnings. Core Earnings, as defined in the Management Agreement, means the net income (loss) attributable to the holders of the Company’s common stock and Class A common stock and, without duplication, the holders of the Company’s subsidiaries’ equity securities (other than the Company or any of the Company’s subsidiaries), computed in accordance with GAAP, including realized gains and losses not otherwise included in net income (loss), and excluding (i) non-cash equity compensation expense, (ii) the incentive compensation, (iii) depreciation and amortization, (iv) any unrealized gains or losses, including an allowance for credit losses, or other similar non-cash items that are included in net income for the applicable period, regardless of whether such items are included in other comprehensive income or loss or in net income and (v) one-time events pursuant to changes in GAAP and certain material non-cash income or expense items, in each case after discussions between the Manager and the Company’s independent directors and approved by a majority of the Company’s independent directors. For long as any shares of Series B Preferred Stock remain issued and outstanding, the Manager has agreed to reduce by 50% the base management fee attributable to the inclusion of the Series B Preferred Stock in the Company’s Equity, such that the base management fee rate applicable to the Series B Preferred Stock included in the equity base will equal 0.75% per annum, instead of 1.50% per annum as provided in the Management Agreement. Management Fees Incurred and Paid for the three months ended March 31, 2021 and 2020 For the three months ended March 31, 2021 and 2020, the Company incurred and paid the following management fees and incentive management fees pursuant to the Management Agreement (dollars in thousands): Three Months Ended March 31, 2021 2020 Incurred Management Agreement fees $ 5,094 $ 5,000 Incentive Management Fee — — Total Fees Incurred $ 5,094 $ 5,000 Paid Management Fee $ 5,358 $ 5,623 Incentive Management Fee — 1,629 Total Fees Paid $ 5,358 $ 7,252 Management fees and incentive management fees included in payable to affiliates on the consolidated balance sheets at March 31, 2021 and December 31, 2020 are $5.1 million and $5.4 million, respectively. No incentive management fee was earned during the three months ended March 31, 2021. Termination Fee A termination fee would be due to the Manager upon termination of the Management Agreement by the Company absent a cause event. The termination fee would also be payable to the Manager upon termination of the Management Agreement by the Manager if the Company materially breaches the Management Agreement. The termination fee is equal to three times the sum of (x) the average annual base management fee and (y) the average annual incentive compensation earned by the Manager, in each case during the 24-month period immediately preceding the most recently completed calendar quarter prior to the date of termination. Other Related Party Transactions The Manager or its affiliates is responsible for the expenses related to the personnel of the Manager and its affiliates who provide services to the Company. However, the Company does reimburse the Manager for agreed-upon amounts based upon the Company’s allocable share of the compensation (including, without limitation, annual base salary, bonus, any related withholding taxes and employee benefits) paid to (1) the Manager’s personnel serving as the Company’s chief financial officer based on the percentage of his or her time spent managing the Company’s affairs and (2) other corporate finance, tax, accounting, internal audit, legal risk management, operations, compliance and other non-investment personnel of the Manager or its affiliates who spend all or a portion of their time managing the Company’s affairs, based on the percentage of time devoted by such personnel to the Company’s and the Company’s subsidiaries’ affairs. For the three months ended March 31, 2021 and March 31, 2020, the Manager incurred $0.3 million and $0.3 million, respectively, of expenses that were subject to reimbursement by the Company for services rendered on its behalf by the Manager and its affiliates. For as long as any shares of Series B Preferred Stock (hereafter defined) remain issued and outstanding, the Manager has agreed that it will not seek reimbursement for reimbursable expenses in excess of the greater of (x) $1.0 million per fiscal year and (y) twenty percent (20%) of the Company’s allocable share of such reimbursable expenses pursuant to the Management Agreement per fiscal year. For the quarter ended March 31, 2021, the Company reimbursed to the Manager $250,000 of reimbursable expenses, and the Manager elected not to seek reimbursement for reimbursable amounts in excess thereof. There can be no assurance that the Manager will not seek reimbursement of such expenses in future quarters. If the product of 20% multiplied by eligible reimbursable expenses is expected to exceed $1.0 million annually, the Manager is obligated to inform and review with the Company’s board of directors, the methodology and rationale for such an increase in advance of the delivery to the Company of a written request for reimbursement reflecting such increase. No such notice has been received by the Company as of March 31, 2021. The Company is required to pay the Manager or its affiliates for documented costs and expenses incurred with third parties by the Manager or its affiliates on behalf of the Company, subject to the Company’s review and approval of such costs and expenses. The Company’s obligation to pay for costs and expenses incurred on its behalf is not subject to a dollar limitation. As of March 31, 2021 and December 31, 2020, $0.0 million and $0.2 million, respectively, remained outstanding and payable to the Manager or its affiliates for third party expenses that were incurred on behalf of the Company. All expenses due and payable to the Manager are reflected in the respective expense category of the consolidated statements of income (loss) and comprehensive income (loss) or consolidated balance sheets based on the nature of the item.

Earnings Per Share [Abstract]
Earnings per Share	(12) Earnings per Share The Company calculates its basic and diluted earnings (loss) per share using the two-class method for all periods presented, since the unvested restricted shares of its common stock granted to certain current and former employees and affiliates of the Manager qualify as participating securities. These restricted shares have the same rights as the Company’s other shares of common stock and Class A common stock (which Class A shares were converted to common shares in February 2020), including participating in any dividends, and therefore are included in the Company’s basic and diluted earnings per share calculation. For the three months ended March 31, 2021 and 2020, $0.1 million $0.3 million In connection with the issuance of Series B Preferred Stock and the Warrants described in Note 13, the Company elected the accreted redemption value method whereby the discount created based on the relative fair value of the Warrants to the fair value of the Series B Preferred Stock and the related issuance costs will be accreted as a non-cash dividend on preferred stock over four years using the effective interest method. Such adjustments are included in Accretion of Discount on Series B Cumulative Redeemable Preferred Stock on our Consolidated Statements of Changes in Equity and treated similarly to a dividend on preferred stock for GAAP purposes. For the three months ended March 31, 2021, this adjustment totaled $1.5 million. The computation of diluted earnings per share is based on the weighted average number of participating securities outstanding plus the incremental shares that would be outstanding assuming exercise of warrants issued pursuant to the Company’s issuance of Series B Preferred Stock. The number of incremental shares is calculated utilizing the treasury stock method. For the three months ended March 31, 2021, the Warrants are included in the calculation of diluted earnings per share because the average market price of the Company’s common stock during the three months ended March 31, 2021 was $10.95, which exceeds the strike price of $7.50 per common share for warrants currently outstanding. The following table sets forth the calculation of basic and diluted earnings per common share based on the weighted-average number of shares of common stock outstanding for the three months ended March 31, 2021 (in thousands, except share and per share data): Three Months Ended March 31, 2021 2020 Net Income (Loss) Attributable to TPG RE Finance Trust, Inc. $ 25,831 $ (232,793 ) Participating Securities' Share in Earnings (Loss) (146 ) (268 ) Accretion of Discount on Series B Preferred Stock (1,452 ) — Net Income (Loss) Attributable to Common Stockholders $ 24,233 $ (233,061 ) Weighted Average Common Shares Outstanding, Basic 76,895,615 76,465,322 Incremental units from assumed exercise of warrants 3,777,621 — Weighted Average Common Shares Outstanding, Diluted 80,673,236 76,465,322 Earnings (Loss) Per Common Share, Basic $ 0.32 $ (3.05 ) Earnings (Loss) Per Common Share, Diluted $ 0.30 $ (3.05 )

Stockholders Equity Note [Abstract]
Stockholders' Equity	(13) Stockholders’ Equity Series B Preferred Stock and Warrants to Purchase Shares of Common Stock On May 28, 2020, the Company entered into an Investment Agreement (the “Investment Agreement”) with PE Holder L.L.C., a Delaware limited liability company (the “Purchaser”), an affiliate of Starwood Capital Group Global II, L.P., under which the Company agreed to issue and sell to the Purchaser up to 13,000,000 shares of 11.0% Series B Preferred Stock, par value $0.001 per share (plus any additional such shares paid as dividends pursuant to the Articles Supplementary, the “Series B Preferred Stock”), and Warrants to purchase, in the aggregate, up to 15,000,000 shares (subject to adjustment) of the Company’s Common Stock, for an aggregate cash purchase price of up to $325,000,000. Such purchases may occur in up to three tranches. The Investment Agreement contains market standard provisions regarding board representation, voting agreements, rights to information, and a standstill agreement and registration rights agreement regarding common stock acquired via exercise of Warrants. On May 28, 2020, the Purchaser acquired the initial tranche, consisting of 9,000,000 shares of Series B Preferred Stock and Warrants to purchase up to 12,000,000 shares of Common Stock, for an aggregate price of $225.0 million. The Company retained an option to sell to the Purchaser the second and third tranches on or prior to December 31, 2020, provided notice of intent to sell is delivered to the Purchaser not later than December 11, 2020. Each of the second and third tranches consisted of 2,000,000 shares of Series B Preferred Stock and Warrants to purchase up to 1,500,000 shares of Common Stock, for an aggregate purchase price of $50.0 million per tranche. The Company allowed the option to issue additional shares of Series B Preferred Stock to expire unused. Series B Preferred Stock The Company’s Series B Preferred Stock has a liquidation preference over all other classes of the Company’s equity other than Series A Preferred Stock, which has liquidation preference over the Series B Preferred Stock. Series B Preferred Stock bears a dividend at 11% per annum, accrued daily and compounded semi-annually, which is payable quarterly in cash; provided that up to 2.0% per annum of the liquidation preference may be paid, at the option of the Company, in the form of additional shares of Series B Preferred Stock. Warrants to Purchase Common Stock The Warrants have an initial exercise price of $7.50 per share. The exercise price of the Warrants and shares of Common Stock issuable upon exercise of the Warrants are subject to customary adjustments. The Warrants are exercisable on a net settlement basis and expire on May 28, 2025. The Warrants are classified as equity and were initially recorded at their estimated fair value of $14.4 million with no subsequent remeasurement. None of the Warrants have been exercised as of March 31, 2021. On the issuance date, the Company retained third party valuation experts to assist with estimating the fair value of the Series B Preferred Stock and the Warrants using the binomial lattice model. Based on the Warrants’ relative fair value to the fair value of the Series B Preferred Stock, approximately $14.4 million of the $225.0 million proceeds was allocated to the Warrants, creating a corresponding preferred stock discount in the same amount. The Company elected the accreted redemption value method whereby this discount will be accreted over four years using the effective interest method, resulting in an increase in the carrying value of the Series B Preferred Stock. Additionally, $14.2 million of costs directly related to the issuance will be accreted using the effective interest method. Such adjustments are included in Accretion of Discount on Series B Cumulative Redeemable Preferred Stock on our Consolidated Statements of Changes in Equity and treated similarly to a dividend on preferred stock for GAAP purposes. Conversion of Class A Shares Between January 22, 2020 and January 24, 2020, the Company received requests to convert all of the outstanding shares of the Company’s Class A common stock into shares of the Company’s common stock. Accordingly, all of the outstanding shares of the Company’s Class A common stock were retired and returned to the authorized but unissued shares of Class A common stock of the Company, and the holders of shares of the Class A common stock were issued an aggregate of 1,136,665 shares of the Company’s common stock. On February 14, 2020, the Company filed Articles Supplementary with the State Department of Assessments and Taxation of Maryland to reclassify and designate all 2,500,000 authorized but unissued shares of the Company’s Class A common stock as additional shares of undesignated common stock of the Company. The Articles Supplementary became effective upon filing on February 14, 2020. As a result, as of March 31, 2021, there are no shares of the Company’s Class A common stock authorized or outstanding. Equity Distribution Agreement On March 7, 2019, the Company and the Manager entered into an equity distribution agreement with each of Citigroup Global Markets Inc., J.P. Morgan Securities LLC, JMP Securities LLC, Wells Fargo Securities, LLC and TPG Capital BD, LLC (each a “Sales Agent” and, collectively, the “Sales Agents”) relating to the issuance and sale by the Company of shares of its common stock pursuant to a continuous offering program. In accordance with the terms of the equity distribution agreement, the Company may, at its discretion and from time to time, offer and sell shares of its common stock having an aggregate gross sales price of up to $125.0 million through the Sales Agents, each acting as the Company’s agent. The offering of shares of the Company’s common stock pursuant to the equity distribution agreement will terminate upon the earlier of (1) the sale of shares of the Company’s common stock subject to the equity distribution agreement having an aggregate gross sales price of $125.0 million and (2) the termination of the equity distribution agreement by the Sales Agents or the Company at any time as set forth in the equity distribution agreement. At March 31, 2021, cumulative gross proceeds issued under the equity distribution agreement totaled $50.9 million, leaving $74.1 million available for future issuance subject to the direction of management, and market conditions. Each Sales Agent will be entitled to commissions in an amount not to exceed 1.75% of the gross sales prices of shares of the Company’s common stock sold through it, as the Company’s agent. For the three months ended March 31, 2021, the Company sold no shares of common stock under this arrangement. For the three months ended March 31, 2020, the Company sold $0.6 million shares of common stock at a weighted average price per share of $20.53 and gross proceeds of $12.9 million, and paid commissions totaling $0.2 million. Dividends Upon the approval of the Company’s Board of Directors, the Company accrues dividends. Dividends are paid first to the holders of the Company’s Series A preferred stock at the rate of 12.5% of the total $0.001 million liquidation preference per annum plus all accumulated and unpaid dividends thereon, then to holders of the Company’s Series B Preferred Stock at the rate of 11.0% per annum of the $25.00 per share liquidation preference, and then to the holders of the Company’s common stock. The Company intends to distribute each year substantially all of its taxable income to its stockholders to comply with the REIT provisions of the Internal Revenue Code of 1986, as amended. The Board of Directors will determine whether to pay future dividends, entirely in cash, or in a combination of stock and cash based on facts and circumstances at the time such decisions are made. On March 15, 2021, the Company’s Board of Directors declared and approved a cash dividend for the first quarter of 2021 in the amount of $0.20 per share of common stock, or $15.5 million in the aggregate, which was paid on April 23, 2021 to holders of record of the Company’s common stock as of March 26, 2021. On March 15, 2021, the Company’s Board of Directors declared a cash dividend for the first quarter of 2021 in the amount of $0.68 per share of Series B Preferred Stock, or $6.1 million in the aggregate, which dividend was paid on March 31, 2021 to the holder of record of our Series B Preferred Stock as of March 15, 2021. On March 17, 2020, the Company’s Board of Directors declared a dividend for the first quarter of 2020 in the amount of $0.43 per share of common stock, or $33.2 million in the aggregate, which was payable on April 24, 2020 to holders of record of the Company’s common stock as of March 27, 2020. This dividend was paid on July 14, 2020. As of March 31, 2021 and December 31, 2020, $15.5 million and $29.5 million, respectively, remain unpaid and are reflected in dividends payable on the Company’s consolidated balance sheets.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(15) Commitments and Contingencies Impact of COVID-19 Due to the current COVID-19 pandemic in the United States and globally, the Company’s borrowers and their tenants, the properties securing the Company’s investments, and the economy as a whole have been, and will continue to be, adversely impacted. The magnitude and duration of COVID-19 and its impact on the Company’s borrowers and their tenants, cash flows and future results of operations could be significant and will largely depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity and mutated strains of COVID-19, the availability of a treatment or effectiveness of vaccines approved for COVID-19, and reactions by consumers, companies, governmental entities and capital markets. The prolonged duration and impact of COVID-19 has and could further materially disrupt the Company’s business operations and impact its financial performance. Unfunded Commitments As part of its lending activities, the Company commits to certain funding obligations which are not advanced at closing and that have not been recognized in the Company’s consolidated financial statements. These commitments to extend credit are made as part of the Company’s portfolio of loans held for investment. The aggregate amount of unrecognized unfunded loan commitments existing at March 31, 2021 and December 31, 2020 was $401.7 million and $423.5 million, respectively. The Company recorded an allowance for credit losses on loan commitments that are not unconditionally cancellable by the Company of $2.1 million and $2.9 million at March 31, 2021 and December 31, 2020 which is included in accrued expenses and other liabilities on the Company’s consolidated balance sheets. Litigation From time to time, the Company may be involved in various claims and legal actions arising in the ordinary course of business. The Company establishes an accrued liability for loss contingencies when a settlement arising from a legal proceeding is both probable and reasonably estimable. If a legal matter is not probable and reasonably estimable, no such liability is recorded. Examples of this include (i) early stages of a legal proceeding, (ii) damages that are unspecified or cannot be determined, (iii) discovery has not started or is incomplete or (iv) there is uncertainty as to the outcome of pending appeals or motions. If these items exist, an estimated range of potential loss cannot be determined and as such the Company does not record an accrued liability. As of March 31, 2021 and December 31, 2020, the Company was not involved in any material legal proceedings and has not recorded an accrued liability for loss contingencies.

Impact of COVID-19 on Concentration of Credit Risk The potential negative impacts on the Company’s business caused by COVID-19 may be heightened by the fact that the Company is not required to observe specific diversification criteria, which means that the Company’s investments may be concentrated in certain property types, geographical areas or loan categories that are more adversely affected by COVID-19 than other property types, geographical areas or loan categories. For example, certain of the loans in the Company’s loan portfolio are secured by office buildings, hotels and retail properties. Federal and state mandates implemented to control the spread of COVID-19, including restrictions on freedom of movement and business operations such as travel bans, border closings, business closures, quarantines and shelter-in-place orders, have and are likely to continue to negatively impact the hotel and retail industries, which could adversely affect the Company’s investments in assets secured by properties that operate in these industries. Also, changes in how certain types of commercial properties are used while maintaining social distancing and other techniques intended to control the impact of COVID-19 (for example, office buildings may be adversely impacted by a possible reversal in the recent trend toward increased densification of office space, or a preference by office users for suburban properties less reliant on public transportation to safely deliver their employees to and from the workplace) have and are likely to impact our investments secured by these properties. Additional regional surges in infection rates due to COVID-19 variants, reversed re-openings, uncertainty regarding the effectiveness of vaccines approved for COVID-19, or high proportions of vaccine hesitancy in certain regions, could adversely affect the Company’s loan investments secured by properties in these regions so impacted.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The interim consolidated financial statements include the Company’s accounts, consolidated variable interest entities for which the Company is the primary beneficiary, and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated. The Company believes it has made all necessary adjustments, consisting of only normal recurring items, so that the consolidated financial statements are presented fairly and that estimates made in preparing the consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These interim consolidated financial statements should be read in conjunction with the Company’s Form 10-K filed with the SEC on February 24, 2021.
Risks and Uncertainties	Risks and Uncertainties The coronavirus pandemic (“COVID-19”) resulted in broad challenges globally, has contributed to significant volatility in financial markets and continues to adversely impact global commercial activity. The impact of the outbreak has evolved rapidly around the globe, with many countries taking drastic measures to limit the spread of the virus by instituting quarantines or lockdowns and imposing travel restrictions. Such actions have created significant disruptions to global supply chains, and adversely impacted several industries, including but not limited to, airlines, hospitality, retail and the broader real estate industry. COVID-19 has had a continued and prolonged adverse impact on economic and market conditions and triggered a period of global economic slowdown which has and could continue to have a material adverse effect on the Company’s results and financial condition. Many jurisdictions have re-opened with social distancing measures implemented to curtail the spread of COVID-19, and multiple vaccines have been approved for use in the United States. Although the Company has observed preliminary signs of economic recovery, the Company cannot predict the time required for a meaningful economic recovery to take place. Additional surges in new cases of COVID-19 and mutated strains of the virus have caused additional quarantines and lockdowns, which could delay any economic recovery. The nationwide vaccination program is ongoing and its effectiveness remains uncertain. These factors could further materially and adversely affect the Company’s results and financial condition. The full impact of COVID-19 on the real estate industry, the credit markets and consequently on the Company’s financial condition and results of operations is uncertain and cannot be predicted currently since it depends on several factors beyond the control of the Company including, but not limited to (i) the uncertainty surrounding the severity and duration of the outbreak, including possible recurrences and differing economic and social impacts of the outbreak in various regions of the United States, (ii) the effectiveness of the United States public health response, (iii) the pandemic’s impact on the United States and global economies, (iv) the timing, scope and effectiveness of additional governmental responses to the pandemic, (v) the timing and speed of economic recovery, including the availability of a treatment and effectiveness of vaccines approved for COVID-19, (vi) changes in how certain types of commercial property are used while maintaining social distancing and other techniques intended to control the impact of COVID-19, and (v i i) the negative impact on the Company’s borrowers, real estate values and cost of capital.
Reclassifications	Reclassifications Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the presentation of the Company’s current period consolidated financial statements. These reclassifications had no effect on the Company’s previously reported net income. Amounts related to Collateralized Loan Obligation Proceeds Held at Trustee were reclassified from in prior period balance sheet to conform to current period presentation.
Use of Estimates	Use of Estimates The preparation of the interim consolidated financial statements in conformity with GAAP requires estimates of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities at the date of the interim consolidated financial statements. Actual results could differ from management’s estimates, and such differences could be material. Significant estimates made in the interim consolidated financial statements include, but are not limited to, the adequacy of our allowance for credit losses and the valuation inputs related thereto and the valuation of financial instruments. Actual amounts and values as of the balance sheet dates may be materially different than the amounts and values reported due to the inherent uncertainty in the estimation process and the limited availability of observable pricing inputs due to market dislocation resulting from the COVID-19 pandemic. Also, future amounts and values could differ materially from those estimates due to changes in values and circumstances after the balance sheet date and the limited availability of observable prices.
Principles of Consolidation	Principles of Consolidation Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810— Consolidation (“ASC 810”) is a VIE and is consolidated in accordance with GAAP. See Note 6 for details regarding issuance of TRTX 2021-FL4. At each reporting date, the Company reconsiders its primary beneficiary conclusions for all its VIEs to determine if its obligation to absorb losses of, or its rights to receive benefits from, the VIE could potentially be more than insignificant, and will consolidate or not consolidate in accordance with GAAP. See Note 6 for details.
Revenue Recognition	Revenue Recognition Interest income on loans is accrued using the interest method based on the contractual terms of the loan, adjusted for expected or realized credit losses, if any. The objective of the interest method is to arrive at periodic interest income, including recognition of fees and costs, at a constant effective yield. Premiums, discounts, and origination fees are amortized or accreted into interest income over the lives of the loans using the interest method, or on a straight-line basis when it approximates the interest method. Extension and modification fees are accreted into income on a straight-line basis, when it approximates the interest method, over the related extension or modification period. Exit fees are accreted into interest income on a straight-line basis, when it approximates the interest method, over the lives of the loans to which they relate unless they can be waived by the Company or a co-lender in connection with a loan refinancing, or if timely collection of principal and interest is doubtful. Prepayment penalties from borrowers are recognized as interest income when received. Certain of the Company’s loan investments have in the past, and may in the future, provide for additional interest based on the borrower’s operating cash flow or appreciation of the underlying collateral. Such amounts are considered contingent interest and are reflected as interest income only upon certainty of collection. Certain of the Company’s loan investments have in the past, and may in the future, provide for the accrual of interest (in part, or in whole) instead of its current payment in cash, with the accrued interest (“PIK interest”) added to the unpaid principal balance of the loan. Such PIK interest is recognized currently as interest income unless the Company concludes eventual collection is unlikely, in which case the PIK interest is written off. All interest accrued but not received for loans placed on non-accrual status is subtracted from interest income at the time the loan is placed on non-accrual status . Based on the Company’s judgment as to the collectability of principal, a loan on non-accrual status is either accounted for on a cash basis, where interest income is recognized only upon receipt of cash for interest payments, or on a cost-recovery basis, where all cash receipts reduce the loan’s carrying value, and interest income is only recorded when such carrying value has been fully recovered.
Loans Held for Investment	Loans Held for Investment Loans that the Company has the intent and ability to hold for the foreseeable future, or until maturity or repayment, are reported at their outstanding principal balances net of cumulative charge-offs, interest applied to principal (for loans accounted for using the cost recovery method), unamortized premiums, discounts, loan origination fees and costs. Loan origination fees and direct loan origination costs are deferred and recognized in interest income over the estimated life of the loans using the interest method, or on a straight-line basis when it approximates the interest method, adjusted for actual prepayments. Accrued but not yet collected interest is separately reported as accrued interest and fees receivable on the Company’s consolidated balance sheets. When loans are designated as held for investment, the Company’s intent is to hold the loans for the foreseeable future or until maturity or repayment. If subsequent changes in real estate or capital markets occur, the Company may change its intent or its assessment of its ability to hold these loans. Once a determination has been made to sell such loans, they are immediately transferred to loans held for sale and carried at the lower of cost or fair value in accordance with GAAP.
Non-Accrual Loans	Non-Accrual Loans Loans are placed on non-accrual status when the full and timely collection of principal and interest is doubtful, generally when: management determines that the borrower is incapable of, or has ceased efforts toward, curing the cause of a default; the loan becomes 90 days or more past due for principal and interest; or the loan experiences a maturity default. The Company considers an account past due when an obligor fails to pay substantially all (defined as 90%) of the scheduled contractual payments by the due date. In each case, the period of delinquency is based on the number of days payments are contractually past due. A loan may be returned to accrual status if all delinquent principal and interest payments are brought current, and collectability of the remaining principal and interest payments in accordance with the loan agreement is reasonably assured. Loans that in the judgment of the Company’s external manager, TPG RE Finance Trust Management, L.P., a Delaware limited partnership (the “Manager”), are adequately secured and in the process of collection are maintained on accrual status, even if they are 90 days or more past due.
Troubled Debt Restructurings	Troubled Debt Restructurings A loan is accounted for and reported as a troubled debt restructuring (“TDR”) when, for economic or legal reasons, the Company grants a concession to a borrower experiencing financial difficulty that the Company would not otherwise consider. The Company does not consider a restructuring that includes an insignificant delay in payment as a concession. A delay may be considered insignificant if the payments subject to the delay are insignificant relative to the unpaid principal balance of the loan or collateral value, and the contractual amount due, or the delay in timing of the restructured payment period, is insignificant relative to the frequency of payments, the debt’s original contractual maturity or original expected duration. TDRs that are performing and on accrual status as of the date of the modification remain on accrual status. TDRs that are non-performing as of the date of modification usually remain on non-accrual status until the prospect of future payments in accordance with the modified loan agreement is reasonably assured, which is generally demonstrated when the borrower maintains compliance with the restructured terms for a predetermined period. TDRs with temporary below-market concessions remain designated as a TDR regardless of the accrual or performance status until the loan is paid off. However, if the TDR loan has been modified in a subsequent restructure with market terms and the borrower is not currently experiencing financial difficulty, then the loan may be de-designated as a TDR.
Allowance for Credit Losses for Loans Held for Investment	Credit Losses Allowance for Credit Losses for Loans Held for Investment On January 1, 2020, the Company adopted Accounting Standard Update (“ASU”) 2016-13, Financial Instruments-Credit Losses, and subsequent amendments, which replaced the incurred loss methodology with an expected loss model known as the Current Expected Credit Loss ("CECL") model. The initial CECL reserve recorded on January 1, 2020 is reflected as a direct charge to retained earnings on the Company’s consolidated statements of changes in equity. Subsequent changes to the CECL reserve are recognized through net income on the Company’s consolidated statements of income (loss) and comprehensive income (loss). The allowance for credit losses measured under the CECL accounting framework represents an estimate of current expected losses for the Company’s existing portfolio of loans held for investment, and is presented as a valuation reserve on the Company’s consolidated balance sheets. Expected credit losses inherent in non-cancelable unfunded loan commitments are accounted for as separate liabilities included in accrued expenses and other liabilities on the consolidated balance sheets. The allowance for credit losses for loans held for investment, as reported in the Company’s consolidated balance sheets, is adjusted by a credit loss benefit (expense), which is reported in earnings in the consolidated statements of income (loss) and comprehensive income (loss) and reduced by the charge-off of loan amounts, net of recoveries and additions related to purchased credit-deteriorated (“PCD”) assets, if relevant. The allowance for credit losses includes a modeled component and an individually-assessed component. The Company has elected to not measure an allowance for credit losses on accrued interest receivables related to all of its loans held for investment because it writes off uncollectable accrued interest receivable in a timely manner pursuant to its non-accrual policy, described above. The Company considers key credit quality indicators in underwriting loans and estimating credit losses, including but not limited to: the capitalization of borrowers and sponsors; the expertise of the borrowers and sponsors in a particular real estate sector and geographic market; collateral type; geographic region; use and occupancy of the property; property market value; loan-to-value (“LTV”) ratio; loan amount and lien position; debt service and coverage ratio; the Company’s risk rating for the same and similar loans; and prior experience with the borrower and sponsor. This information is used to assess the financial and operating capability, experience and profitability of the sponsor/borrower. Ultimate repayment of the Company’s loans is sensitive to interest rate changes, general economic conditions, liquidity, LTV ratio, existence of a liquid investment sales market for commercial properties, and availability of replacement short-term or long-term financing. The loans in the Company’s commercial mortgage loan portfolio are secured by collateral in the following property types: office; multifamily; hotel; mixed-use; condominium; and retail. The Company’s loans are typically collateralized by real estate, or in the case of mezzanine loans, by a partnership interest or similar equity interest in an entity that owns real estate. As a result, the Company regularly evaluates on a loan-by-loan basis, typically no less frequently than quarterly, the extent and impact of any credit deterioration associated with the performance and/or value of the underlying collateral property, and the financial and operating capability of the borrower/sponsor. The Company also evaluates the financial strength of loan guarantors, if any, and the borrower’s competency in managing and operating the property or properties. In addition, the Company considers the overall economic environment, real estate sector, and geographic sub-market in which the borrower operates. Such analyses are completed and reviewed by asset management personnel and evaluated by senior management, who utilize various data sources, including, to the extent available (i) periodic financial data such as property occupancy, tenant profile, rental rates, operating expenses, the borrower’s exit plan, and capitalization and discount rates, (ii) site inspections, (iii) sales and financing comparables, (iv) current credit spreads for refinancing and (v) other market data. Quarterly, the Company evaluates the risk of all loans and assigns a risk rating based on a variety of factors, grouped as follows: (i) loan and credit structure, including the as-is LTV structural features; (ii) quality and stability of real estate value and operating cash flow, including debt yield, property type, dynamics of the geography, property type and local market, physical condition, stability of cash flow, leasing velocity and quality and diversity of tenancy; (iii) performance against underwritten business plan; and (iv) quality, experience and financial condition of sponsor, borrower and guarantor(s). Based on a 5-point scale, the Company’s loans are rated “1” through “5,” from least risk to greatest risk, respectively, which ratings are defined as follows: 1- Outperform—Exceeds performance metrics (for example, technical milestones, occupancy, rents, net operating income) included in original or current credit underwriting and business plan; 2- Meets or Exceeds Expectations—Collateral performance meets or exceeds substantially all performance metrics included in original or current underwriting / business plan; 3- Satisfactory—Collateral performance meets or is on track to meet underwriting; business plan is met or can reasonably be achieved; 4- Underperformance—Collateral performance falls short of original underwriting, material differences exist from business plan, or both; technical milestones have been missed; defaults may exist, or may soon occur absent material improvement; and 5- Default/Possibility of Loss—Collateral performance is significantly worse than underwriting; major variance from business plan; loan covenants or technical milestones have been breached; timely exit from loan via sale or refinancing is questionable; significant risk of principal loss. The Company generally assigns a risk rating of “3” to all loan investments originated during the most recent quarter, except in the case of specific circumstances warranting an exception. The Company’s CECL reserve reflects its estimation of the current and future economic conditions that impact the performance of the commercial real estate assets securing the Company’s loans. These estimations include unemployment rates, interest rates, price indices for commercial property, and other macroeconomic factors that may influence the likelihood and magnitude of potential credit losses for the Company’s loans during their anticipated term. The Company licenses certain macroeconomic financial forecasts to inform its view of the potential future impact that broader economic conditions may have on its loan portfolio’s performance. The forecasts are embedded in the licensed model that the Company uses to estimate its CECL reserve as discussed below . Selection of these economic forecasts requires significant judgment about future events that, while based on the information available to the Company as of the balance sheet date, are ultimately unknowable with certainty, and the actual economic conditions impacting the Company’s portfolio could vary significantly from the estimates the Company made for the periods presented. Due to the COVID-19 pandemic and the dislocation it has caused to the national economy, the commercial real estate markets, and the capital markets, the Company’s ability to estimate key inputs for estimating the allowance for credit losses has been materially and adversely impacted. Key inputs to the estimate include, but are not limited to, LTV, debt service coverage ratio, current and future operating cash flow and performance of collateral properties, the financial strength and liquidity of borrowers and sponsors, capitalization rates and discount rates used to value commercial real estate properties, and market liquidity based on market indices or observable transactions involving the sale or financing of commercial properties. Estimates made by management are necessarily subject to change due to the lack or sharply limited number of observable inputs and uncertainty regarding the duration of the COVID-19 pandemic and its aftereffects.
Credit Loss Measurement	Credit Loss Measurement The amount of allowance for credit losses is influenced by the size of the Company’s loan portfolio, loan asset quality, risk rating, delinquency status, historic loss experience and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The Company employs two methods to estimate credit losses in its loan portfolio: a loss-given-default (“LGD”) model-based approach utilized for substantially all of its loans; and an individually-assessed approach for loans that the Company concludes are ill-suited for use in the model-based approach, or are individually-assessed based on accounting guidance contained in the CECL framework. Once the expected credit loss amount is determined, an allowance for credit losses equal to the calculated expected credit loss is established. Consistent with ASC 326, a loan will be charged off through the allowance for credit losses when it is deemed non-recoverable upon a realization event. This is generally at the time the loan receivable is settled, transferred or exchanged, but non-recoverability may also be concluded by the Company if, in its determination, it is nearly certain that all amounts due will not be collected. This loss shall equal the difference between the cash received, or expected to be received, and the book value of the asset. Factors considered by management in determining if the expected credit loss is permanent or not recoverable include whether management judges the loan to be uncollectible; that is, repayment is deemed to be delayed beyond reasonable time frames, or the loss becomes evident due to the borrower’s lack of assets and liquidity, or the borrower’s sponsor is unwilling or unable to support the loan. This policy is reflective of the investor’s economics as it relates to the ultimate realization of the loan. Allowance for Credit Losses for Loans Held for Investment – Model-Based Approach The model-based approach to measure the allowance for credit losses relates to loans which are not individually-assessed. The Company licenses from Trepp, LLC historical loss information, incorporating loan performance data for over 100,000 commercial real estate loans dating back to 1998, in an analytical model to compute statistical credit loss factors (i.e., probability-of-default and loss-given-default). These statistical credit loss factors are utilized together with individual loan information to estimate the allowance for credit losses. This methodology considers the unique characteristics of the Company’s commercial mortgage loan portfolio and individual assets within the portfolio by considering individual loan risk ratings, delinquency statuses and other credit trends and risk characteristics. Further, the Company incorporates its expectations about the impact of current conditions and reasonable and supportable forecasts on expected future credit losses in deriving its estimate. For the period beyond which the Company is able to make reasonable and supportable forecasts, the Company reverts to unadjusted historical loan loss information based on systematic methodology determined at the input level. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense. Allowance for Credit Losses for Loans Held for Investment – Individually-Assessed Approach In instances where the unique attributes of a loan investment render it ill-suited for the model-based approach because it no longer shares risk characteristics with other loans, or because the Company concludes repayment of the loan is entirely collateral-dependent, or when it is deemed probable that the Company will not be able to collect all amounts due according to the contractual terms of the loan, the Company separately evaluates the amount of expected credit loss using other real estate valuation techniques, considering substantially the same credit factors as utilized in the model-dependent method. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, if repayment is expected solely from the collateral, as determined by management using valuation techniques, frequently discounted cash flow. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than the operation) of the collateral.
Unfunded Loan Commitments	Unfunded Loan Commitments The Company’s first mortgage loans often contain provisions for future funding conditioned upon the borrower’s execution of its business plan with respect to the underlying collateral property securing the loan. These deferred fundings are typically for base building work, tenant improvement costs and leasing commissions, and occasionally to fund forecasted operating deficits during lease-up, or for interest reserves. These deferred funding commitments may be for specific periods, often require satisfaction by the borrower of conditions precedent, and may contain termination clauses at the option of the borrower or, more rarely, at the Company’s option. The total amount of unfunded commitments does not necessarily represent actual amounts that may be funded in cash in the future, since commitments may expire without being drawn, may be cancelled if certain conditions are not satisfied by the borrower, or borrowers may elect not to borrow some or all of the unused commitment. The Company does not recognize these unfunded loan commitments in its consolidated financial statements. The Company applies its expected credit loss estimates to all future funding commitments that cannot be contractually terminated at the Company’s option. The Company maintains a separate allowance for credit losses from unfunded loan commitments, which is included in accrued expenses and other liabilities on the consolidated balance sheets. The Company estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Company and applies the loss factors used in the allowance for credit loss methodology described above to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan.
CRE Debt Securities	CRE Debt Securities In the past, the Company acquired CRE debt securities for investment purposes. The Company designated CRE debt securities as available-for-sale (“AFS”) on the acquisition date. CRE debt securities that were classified as AFS were recorded at fair value through other comprehensive income or loss in the Company’s consolidated financial statements. The Company recognized interest income on its CRE debt securities using the interest method, or on a straight-line basis when it approximated the effective interest method, with any premium or discount amortized or accreted into interest income based on the respective outstanding principal balance and corresponding contractual term of the CRE debt security. Accrued but not yet collected interest was separately reported as accrued interest receivable on the Company’s consolidated balance sheets. The Company used a specific identification method when determining the cost of a CRE debt security sold and the amount of unrealized gain or loss reclassified from accumulated other comprehensive income or loss into earnings on the trade date. AFS debt securities in unrealized loss positions were evaluated for impairment related to credit losses at least quarterly. For the purpose of identifying and measuring impairment, any applicable accrued interest was excluded from both the fair value and the amortized cost basis. The Company had elected to write off accrued interest by reversing interest income in the event the accrued interest is deemed uncollectible, generally when the security became 90 days or more past due for principal and interest. The Company first assessed whether it intended to sell the debt security or more likely than not was required to sell the debt security before recovery of its amortized cost basis. If either criterion regarding intent or requirement to sell was met, the debt security’s amortized cost basis was written down to its fair value and the write down was charged against the allowance for credit losses, with any incremental impairment reported in earnings as a loss in the consolidated statements of income (loss) and comprehensive income (loss). Any AFS debt security in an unrealized loss position which the Company d id not intend to sell or was not more likely than not required to sell before recovery of the amortized cost basis wa s assessed for expected credit losses. The performance indicators considered for CRE debt securities relate d to the underlying assets and include d default rates, delinquency rates, percentage of nonperforming assets, debt-to-collateral ratios, third-party guarantees, current levels of subordination, vintage, geographic concentration, analyst reports and forecasts, credit ratings and other market data. In assessing whether a credit loss exists, the Company compare d the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected wa s less than the amortized cost basis for the security, a credit loss exist ed and an allowance for credit losses wa s recorded, limited by the amount the fair value wa s less than amortized cost basis. Declines in fair value of AFS debt securities in an unrealized loss position that were not due to credit losses, such as declines due to changes in market interest rates, were recorded through other comprehensive income. Any impairment that had not been recorded through an allowance for credit losses was recognized in other comprehensive income. Unrealized gains and losses on AFS debt securities presented in the consolidated statements of income (loss) and comprehensive income (loss) included the reversal of unrealized gains and losses at the time gains or losses were realized.
Real Estate Owned	Real Estate Owned Real estate acquired as a result of foreclosure or by deed-in-lieu of foreclosure is classified as real estate owned (REO) held for investment until the Company makes a determination to sell. The Company's cost basis in REO is equal to the estimated fair value of the collateral at the date of acquisition, less estimated costs to sell. The estimated fair value of the REO is determined using a discounted cash flow model using inputs that include the highest and best use for each asset, estimated future values based on extensive discussions with local brokers, investors and other market participants, the estimated holding period for the asset, and discount rates that reflect estimated investor return requirements for the risks associated with the expected use of each asset. If the fair value of the REO is lower than the carrying value of the loan, the difference, along with any previously recorded specific CECL reserve, is recorded as a realized loss in the consolidated statements of income (loss) and comprehensive income (loss). Thereafter, events or circumstances may occur that result in a material and sustained decrease in the cash flows generated from the assets, potentially leading to impairment. REO is not measured at fair value on an ongoing basis but subject to fair value adjustments only in certain circumstances, such as when there is evidence of impairment. Any impairment loss, revenue and expenses from operations of the properties and resulting gains or losses on sale are included within the consolidated statements of income (loss) and comprehensive income (loss) in Other Income, net.
Portfolio Financing Arrangements	Portfolio Financing Arrangements The Company finances its portfolio of loans, or participation interests therein, and REO using secured credit agreements, including secured credit facilities, mortgage loans payable, and collateralized loan obligations. The related borrowings are recorded as separate liabilities on the Company’s consolidated balance sheets. Interest income earned on the investments and interest expense incurred on the related borrowings are reported separately on the Company’s consolidated statements of income (loss) and comprehensive income (loss). In certain instances, the Company creates structural leverage through the co-origination or non-recourse syndication of a senior loan interest to a third party. For all such syndications the Company has completed through March 31, 2021, the Company transferred, on a non-recourse basis, 100% of the senior mortgage loan that the Company originated to a third-party lender, and retained as a loan investment a separate mezzanine loan investment secured by a pledge of the equity in the mortgage borrower. With respect to the senior mortgage loan so transferred, the Company retains: no control over the mortgage loan; no economic interest in the mortgage loan; and no recourse to the purchaser or the borrower. Consequently, based on these circumstances and because the Company does not have any continuing involvement with the transferred senior mortgage loan, these syndications are accounted for as sales under GAAP and are removed from the Company’s consolidated financial statements at the time of transfer. The Company’s consolidated balance sheets only include the separate mezzanine loan remaining after the transfer. For more information regarding the Company’s portfolio financing arrangements, see Note 7.
Fair Value Measurements	Fair Value Measurements The Company follows ASC 820-10, Fair Value Measurements and Disclosures “ASC 820-10” Level I Level II Level III For certain financial instruments, the various inputs that management uses to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for such financial instrument is based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The Company may use valuation techniques consistent with the market and income approaches to measure the fair value of its assets and liabilities. The market approach uses third-party valuations and information obtained from market transactions involving identical or similar assets or liabilities. The income approach uses projections of the future economic benefits of an instrument to determine its fair value, such as in the discounted cash flow methodology. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. Transfers between levels of the fair value hierarchy are assumed to occur at the end of the reporting period. The following methods and assumptions are used by our Manager to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: • Cash and cash equivalents: the carrying amount of cash and cash equivalents approximates fair value. • Loans held for investment, net: using a discounted cash flow methodology employing a discount rate for loans of comparable credit quality, structure, and LTV based upon appraisal information and current estimates of the value of collateral property performed by the Manager, and credit spreads for loans of comparable risk (as determined by the Manager based on the factors previously described) as corroborated by inquiry of other market participants. • Secured credit facilities and mortgage loan payable: based on the rate at which a similar secured credit facility or mortgage loan payable would currently be priced, as corroborated by inquiry of other market participants. • CRE Collateralized Loan Obligations, net: utilizing indications of value from dealers active in trading similar or substantially similar securities, observable quotes from market data services, reported prices and spreads for recent new issues, and Manager estimates of the credit spread on which similar bonds would be issued, or traded, in the new issue and secondary markets. • Other assets and liabilities subject to fair value measurement, including receivables, payables and accrued liabilities have carrying values that approximate fair value due to their short-term nature. As discussed above, market-based or observable inputs are generally the preferred source of values for purposes of measuring the fair value of the Company’s assets under GAAP. The commercial property investment sales and commercial mortgage loan markets have and continue to experience extreme volatility, sharply reduced transaction volume, reduced liquidity, and disruption as a result of COVID-19, which has made it more difficult to rely on market-based inputs in connection with the valuation of the Company’s assets under GAAP. Key valuation inputs include, but are not limited to, future operating cash flow and performance of collateral properties, the financial strength and liquidity of borrowers and sponsors, capitalization rates and discount rates used to value commercial real estate properties, and observable transactions involving the sale or financing of commercial properties. In the absence of market inputs, GAAP permits the use of management assumptions to measure fair value. However, the considerable market volatility and disruption caused by COVID-19 and the considerable uncertainty regarding the ultimate impact and duration of the pandemic have made it more difficult for the Company’s management to formulate assumptions to measure the fair value of the Company’s assets.
Income Taxes	Income Taxes The Company qualifies and has elected to be taxed as a REIT for U.S. federal income tax purposes under the Internal Revenue Code of 1986, as amended, commencing with its initial taxable year ended December 31, 2014. To the extent that it annually distributes at least 90% of its REIT taxable income to stockholders and complies with various other requirements as a REIT, the Company generally will not be subject to U.S. federal income taxes on its distributed REIT taxable income. In 2017, the Internal Revenue Service issued a revenue procedure permitting “publicly offered” REITs to make elective stock dividends (i.e. dividends paid in a mixture of stock and cash), with at least 20% of the total distribution being paid in cash, to satisfy their REIT distribution requirements. Pursuant to this revenue procedure, the Company may elect to make future distributions of its taxable income in a mixture of stock and cash. If the Company fails to continue to qualify as a REIT in any taxable year and does not qualify for certain statutory relief provisions, the Company will be subject to U.S. federal and state income taxes at regular corporate rates beginning with the year in which it fails to qualify and may be precluded from being able to elect to be treated as a REIT for the Company’s four subsequent taxable years. Even though the Company currently qualifies for taxation as a REIT, the Company may be subject to certain U.S. federal, state, local and foreign taxes on the Company’s income and property and to U.S. federal income and excise taxes on the Company’s undistributed REIT taxable income. Deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period in which the enactment date occurs. Under ASC Topic 740, Income Taxes (“ASC 740”), a valuation allowance is established when management believes it is more likely than not that a deferred tax asset will not be realized. The Company intends to continue to operate in a manner consistent with, and to continue to meet the requirements to be treated as, a REIT for tax purposes and to distribute all of its REIT taxable income. Accordingly, the Company does not expect to pay corporate level federal taxes.
Earnings per Common Share	Earnings per Common Share The Company utilizes the two-class method when assessing participating securities to calculate earnings per common share. Basic earnings per common share is computed by dividing net income attributable to common stockholders (i.e., holders of common stock and, when it was outstanding, Class A common stock), by the weighted-average number of common shares (both common stock and, when it was outstanding, Class A common stock) outstanding during the period. The preferences, rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications and terms and conditions of redemption of the Class A common stock were identical to the common stock, except (1) the Class A common stock was not a “margin security” as defined in Regulation U of the Board of Governors of the U.S. Federal Reserve System (and rulings and interpretations thereunder) and could not be listed on a national securities exchange or a national market system and (2) each share of Class A common stock was convertible at any time or from time to time, at the option of the holder, for one fully paid and non-assessable share of common stock. See Note 13 for details regarding the conversion of Class A common stock. Diluted earnings per share is computed under the more dilutive of the treasury stock method or the two-class method. The computation of diluted earnings per share is based on the weighted average number of participating securities outstanding plus the incremental shares that would be outstanding assuming exercise of warrants (the “Warrants”, see Note 13) issued in connection with the Company’s Series B Cumulative Redeemable Preferred Stock (“Series B Preferred”)
Share-Based Compensation	Share-Based Compensation Share-based compensation consists of awards issued by the Company to certain employees of affiliates of the Manager and certain members of the Company’s Board of Directors. These share-based awards generally vest in installments over a fixed period of time. Deferred stock units granted to the Company’s Board of Directors fully vest on the grant date and accrue dividends that are paid- in kind through additional d eferred stock units on a quarterly basis. Compensation expense is recognized in net income on a straight-line basis over the applicable award ’ s vesting period. Forfeitures of share-based awards are recognized as they occur.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are reflected net of the collateralized loan obligations, secured credit arrangements, and mortgage loan payable on the Company’s consolidated balance sheets. These costs are amortized in interest expense using the interest method, or on a straight-line basis when it approximates the interest method, as follows: (a) for secured credit arrangements other than our CRE CLOs, the initial term of the financing arrangement, or in case of costs directly associated with the loan, over the life of the facility or the loan, whichever is shorter; (b) for deferred financing costs related to mortgage loan payable, the initial maturities of the underlying loan(s) pledged to support the specific borrowing; and (c) for CRE CLOs issued by the Company’s subsidiaries, over the estimated life of the liabilities issued based on the initial maturity dates of the underlying loans currently held by each trust based upon the expected repayment behavior of the loans collateralizing the notes after giving effect to the reinvestment period, all as of the closing date.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash held in banks or invested in money market funds with original maturities of less than 90 days. The Company deposits its cash and cash equivalents with high credit quality institutions to minimize credit risk exposure. The Company maintains cash accounts at several financial institutions, which are insured up to a maximum of $250,000 per account as of March 31, 2021 and December 31, 2019. The balances in these accounts may exceed the insured limits. Pursuant to financial covenants applicable to Holdco, which is the guarantor of the Company’s recourse indebtedness, the Company is required to maintain minimum cash equal to the greater of (i) $10 million or (ii) the product of 5% and the aggregate recourse indebtedness of the Company. To comply with this covenant, the Company held as part of its total cash balances $10.8 million and $19.1 million, respectively, at March 31, 2021 and December 31, 2020.
Restricted Cash	Restricted Cash Restricted cash primarily represents deposit proceeds from potential borrowers which may be returned to borrowers, after deducting transaction costs paid by the Company for the benefit of the borrowers, upon the closing of a loan transaction.
Collateralized Loan Obligation Proceeds Held at Trustee	Collateralized Loan Obligation Proceeds Held at Trustee Collateralized Loan Obligation Proceeds Held at Trustee represent the TRTX 2021-FL4 Ramp-Up Account in an amount of approximately $308.9 million available to purchase eligible collateral interests from the Company during a ramp-up period of approximately six months following the FL4 Closing Date. See Note 6 for details of the TRTX 2021-FL4 issuance. Also included is cash held by the Company’s CRE CLOs pending reinvestment in eligible collateral.
Accounts Receivable from Servicer/Trustee	Accounts Receivable from Servicer/Trustee Accounts receivable from Servicer/Trustee represents cash proceeds from loan activities that have not been remitted to the Company based on established servicing and borrowing procedures. Such amounts are generally held by the Servicer/Trustee for less than 30 days before being remitted to the Company.
Temporary Equity	Temporary Equity Equity instruments that are redeemable for cash or other assets are classified as temporary equity if the instrument is redeemable, at the option of the holder, at a fixed or determinable price on a fixed or determinable date or upon the occurrence of an event that is not solely within the control of the issuer. Redeemable equity instruments are initially carried at the relative fair value of the equity instrument at the issuance date, which is subsequently adjusted at each balance sheet date if the instrument is currently redeemable or probable of becoming redeemable. The Series B Preferred Stock issued in connection with the Investment Agreement described in Note 13 is classified as temporary equity in the accompanying financial statements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Guidance In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional expedients and exceptions to GAAP requirements for modifications to debt agreements, leases, derivatives, and other contracts, related to the expected market transition from LIBOR, and certain other floating rate benchmark indices, or collectively, IBORs, to alternative reference rates. ASU 2020-04 generally considers contract modifications related to reference rate reform to be an event that does not require contract remeasurement at the modification date nor a reassessment of a previous accounting determination. In January 2021, the FASB clarified the scope of that guidance with the issuance of ASU 2021-01, “Reference Rate Reform: Scope.” This ASU provides optional guidance for a limited period of time to ease the burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. This would apply to companies meeting certain criteria that have contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This standard is effective for the Company immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company continues to evaluate the documentation and control processes associated with its assets and liabilities to manage the transition away from LIBOR to an alternative rate endorsed by the Alternative Reference Rates Committee of the Federal Reserve System, and continues to utilize required resources to revise its control and risk management systems to ensure there is no disruption to our day-to-day operations from the transition, when it does occur. The Company will continue to employ prudent risk management as it relates to the potential financial, operational and legal risks associated with the expected cessation of LIBOR, and to ensure that its assets and liabilities generally remain match-indexed following this event. The Company is currently evaluating the impact of ASU 2020-04 on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815 – 40) (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU is part of the FASB’s simplification initiative, which aims to reduce unnecessary complexity in GAAP. The ASU’s amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company is currently evaluating the impact of ASU 2020-06 on its consolidated financial statements. In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC’s regulations. The ASU’s amendments are effective for annual periods beginning after December 15, 2021. The Company is currently evaluating the impact of ASU 2020-04 on its consolidated financial statements.

In either case, the senior mortgage loan (i.e., the non-consolidated senior interest) is not included on the Company’s balance sheet. When the Company creates structural leverage through the co-origination or non-recourse syndication of a senior loan interest to a third-party, the Company retains on its balance sheet a mezzanine loan. Total loan commitment encompasses the entire loan portfolio the Company originated, acquired and financed. At March 31, 2021, the Company had one non-consolidated senior interest outstanding of $132.0 million. (2) Unpaid principal balance includes PIK interest of $5.5 million as of March 31, 2021. ( 3 ) Unfunded loan commitments may be funded over the term of each loan, subject in certain cases to an expiration date or a force-funding date, primarily to finance property improvements or lease-related expenditures by the Company’s borrowers, to finance operating deficits during renovation and lease-up, and in limited instances to finance construction. ( 4 ) As of March 31, 2021, all of the Company’s loans were floating rate and were indexed to LIBOR. In addition to credit spread, all-in yield includes the amortization of deferred origination fees, purchase price premium and discount if any, loan origination costs and accrual of both extension and exit fees. Credit spread and all-in yield for the total portfolio assumes the applicable floating benchmark rate as of March 31, 2021 for weighted average calculations. ( 5 ) Extended maturity assumes all extension options are exercised by the borrower; provided, however, that the Company’s loans may be repaid prior to such date. As of March 31, 2021, based on the unpaid principal balance of the Company’s total loan exposure, 23.0% of the Company’s loans were subject to yield maintenance or other prepayment restrictions and 77.0% were open to repayment by the borrower without penalty.

Summary of Recourse and Market-to-Market Provisions	The Company’s secured credit facilities contain defined mark-to-market provisions that permit the lenders to issue margin calls in the event that the collateral properties underlying the Company’s loans pledged to its lenders experience a non-temporary decline in value or net cash flow (“credit marks”) due to reasons other than capital markets events that result in changing credit spreads for similar borrowing obligations. In connection with one of these borrowing arrangements, the lender is also permitted to issue margin calls to the Company in the event the lender determines capital markets events have caused credit spreads to change for similar borrowing obligations (“spread marks”). Furthermore, in connection with one of these borrowing arrangements, the lender has the right to re-margin the secured credit facility based solely on appraised loan-to-values in the third year of the facility.

No incentive compensation is payable to the Manager with respect to any calendar quarter unless Core Earnings for the 12 most recently completed calendar quarters is greater than zero. For purposes of calculating the Manager’s incentive compensation, the Management Agreement, as amended, specifies that equity securities of the Company or any of the Company’s subsidiaries that are entitled to a specified periodic distribution or have other debt characteristics will not constitute equity securities and will not be included in “Equity” for the purpose of calculating incentive compensation. Instead, the aggregate distribution amount that accrues to such equity securities during the calendar quarter of such calculation will be subtracted from Core Earnings, before incentive compensation for purposes of calculating incentive compensation, unless such distribution is otherwise excluded from Core Earnings.
