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 a Maryland corporation that was incorporated on October 24, 2014 and commenced operations on December 18, 2014 (“Inception”). We are organized as a holding company and conduct our 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. We conduct our operations as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. We generally will not be subject to U.S. federal income taxes on our REIT taxable income to the extent that we annually distribute all of our REIT taxable income to stockholders and maintain our qualification as a REIT. We also operate our business in a manner that permits us to maintain an exclusion from registration under the Investment Company Act of 1940, as amended. 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 and commercial real estate debt securities, including commercial mortgage-backed securities (“CMBS”) and commercial real estate collateralized loan obligation securities (“CRE CLO”). As of March 31, 2019, and December 31, 2018, the Company conducted substantially all of its operations through a Delaware limited liability company, TPG RE Finance Trust Holdco, LLC (“Holdco”), and the Company’s other wholly-owned subsidiaries.

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. 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: impairment; adequacy of provisions for loan losses; and valuation of financial instruments. Principles of Consolidation Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810—Consolidation (“ASC 810”) provides guidance on the identification of a VIE (a variable interest entity for which control is achieved through means other than voting rights) and the determination of which business enterprise, if any, should consolidate the VIE. An entity is considered a VIE if any of the following applies: (1) the equity investors (if any) lack one or more of the essential characteristics of a controlling financial interest; (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support; or (3) the equity investors have voting rights that are not proportionate to their economic interests and the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest. The Company consolidates VIEs in which it is considered to be the primary beneficiary. The primary beneficiary is defined as the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance; and (2) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE. At each reporting date, the Company reconsiders its primary beneficiary conclusion 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 accordingly (see Note 5 for details). Revenue Recognition Interest income on loans is accrued using the interest method based on the contractual terms of the loan, adjusted for credit impairment, 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 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. 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. The Company considers a loan to be non-performing and places the loan on non-accrual status when: (1) management determines the borrower is incapable of, or has ceased efforts toward, curing the cause of a default; (2) the loan becomes 90 days delinquent; or (3) the loan experiences a maturity default. 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 principal and 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. During the three months ended March 31, 2019 and the year end December 31, 2018, no loans were placed on non-accrual status and no losses or impairments were recorded to our loan portfolio. 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 any premiums, discounts, loan origination fees and loan loss allowances, if any. 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. The Company evaluates each loan classified as a loan held for investment for impairment on a quarterly basis. Impairment occurs when it is deemed probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan. If the loan is considered to be impaired, a loan loss allowance is recorded to reduce the carrying value of the loan to the present value of the expected future cash flows discounted at the loan’s contractual effective rate, or the fair value of the collateral securing the impaired loan, less estimated costs to sell such collateral, if recovery of the Company’s investment is expected solely from the sale of such collateral. As part of the quarterly impairment review, the Company evaluates the risk of each loan and assigns a risk rating based on a variety of factors, grouped as follows to include, among other factors: (i) loan and credit structure, including the as-is loan-to-value (“LTV”) and structural features; (ii) quality and stability of real estate value and operating cash flow, including debt yield, property type, dynamics of the geographic, 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- Risk of Impairment/Default—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. Since Inception, the Company has not recognized any impairments on its loan portfolio and has not recorded any loan loss allowances against any of the loans in its portfolio. The Company’s determination of asset-specific loan loss reserves, should any such reserves be necessary, relies on material estimates regarding the fair value of loan collateral. Such losses could be caused by various factors, including, but not limited to, unanticipated adverse changes in the economy or events adversely affecting specific assets, borrowers, industries in which our borrowers operate or markets in which our borrowers or their properties are located. Significant judgment is required when evaluating loans for impairment. The Company’s loans are typically collateralized by real estate, or in the case of mezzanine loans, by a partnership or similar equity interest in an entity that owns real estate. As a result, the Company regularly evaluates on a loan-by-loan basis the extent and impact of any credit deterioration associated with the performance and/or value of the underlying collateral property as well as 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 impairment analyses are completed and reviewed by asset management personnel and evaluated by senior management, who utilize various data sources, including (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. Commercial Mortgage-Backed and Commercial Real Estate Collateralized Loan Obligation Securities The Company acquires CMBS and CRE CLO investments primarily for cash management purposes, and also for investment purposes. The Company designates CMBS and CRE CLO investments as available-for-sale on the acquisition date. CMBS and CRE CLO investments that are classified as available-for-sale are recorded at fair value through other comprehensive income (loss) in the Company’s consolidated financial statements. Additionally, CMBS and CRE CLO investments that are not classified as held-to-maturity and which the Company does not hold for the purpose of selling in the near-term, but may dispose of prior to maturity, are also designated as available-for-sale and are carried at fair value. The Company’s recognition of interest income from its CMBS and CRE CLO investments, including its amortization of premium and discount, follows the Company’s revenue recognition policy as described under “Revenue Recognition” above. The Company uses a specific identification method when determining the cost of a security sold and the amount of unrealized gain or loss reclassified from accumulated other comprehensive income (loss) into earnings. Unrealized losses on securities that, in the judgment of management, are other than temporary are charged against earnings as a loss in the consolidated statements of income and comprehensive income. Significant valuation inputs are Level II in the fair value hierarchy as described below under “Fair Value Measurements”. Portfolio Financing Arrangements The Company finances certain loan and CMBS and CRE CLO investments using secured revolving repurchase agreements, asset-specific financing arrangements, senior secured and secured credit agreements, collateralized loan obligations, and a term loan facility. 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 and comprehensive income. 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, 2019, the Company has transferred 100% of the senior mortgage loan that the Company originated on a non-recourse basis to a third-party lender and has 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 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, and not the non-consolidated senior loan interest sold or co-originated that the Company transferred. As of December 31, 2018, the Company revised its “Note Payable” naming convention in its consolidated balance sheet to “Asset-Specific Financings”. No amounts reported in prior periods were reclassified between financial statement line items and there was no impact to the Company’s financial statements resulting from this naming convention change during the current fiscal year. 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. 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. 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 Earnings per Common Share The Company utilizes the two-class method when assessing participating securities to calculate earnings per common share. Basic and diluted earnings per common share is computed by dividing net income attributable to common stockholders (i.e., holders of common stock and Class A common stock), by the weighted-average number of common shares (both common stock and 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 are identical to the common stock, except (1) the Class A common stock is 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 may not be listed on a national securities exchange or a national market system and (2) each share of Class A common stock is 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. The Class A common stock votes together with the common stock as a single class. Shares of Class A common stock have been issued to, and are owned by, TPG RE Finance Trust Management, L.P., a Delaware limited partnership (the “Manager”), and certain individuals or entities who are or were affiliated with the Manager, and the sale or conversion to common stock by investors of such shares of Class A common stock is subject to certain restrictions. Diluted earnings per common share is calculated by including the effect of dilutive securities. The Company accounts for unvested share-based payment awards that contain non-forfeitable dividend rights or dividend equivalents (whether paid or unpaid) as participating securities, which are included in the computation of earnings per share pursuant to the two-class method. Share-Based Compensation Share-based compensation consists of awards issued by the Company to certain employees of affiliates of our Manager and certain members of our Board of Directors. These share-based awards generally vest in installments over a fixed period of time. Compensation expense is recognized in net income on a straight-line basis over the applicable awards’ vesting period. Forfeitures of share-based awards are recognized as they occur. Deferred Financing Costs Deferred financing costs are reflected net of the collateralized loan obligations and secured financing arrangements 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 over the life of the related obligations. 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, 2019 and December 31, 2018. The balances in these accounts may exceed the insured limits. 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. Accounts Receivable from Servicer/Trustee Accounts receivable from Servicer/Trustee represents cash proceeds from loan and CMBS and CRE CLO investment activities that have not been remitted to the Company based on contractual procedures previously agreed upon. Amounts are generally held by the Servicer/Trustee for less than 60 days before being remitted to the Company. Recently Issued Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace the “incurred loss” model under existing guidance with an “expected loss” model for instruments measured at amortized cost, and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. Upon adoption, and resulting from this change, the Company expects that it will be required to record a loan loss reserve at origination or acquisition of an individual loan or a loan portfolio. ASU 2016-13 also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 and is to be adopted through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently evaluating the impact ASU 2016-13 will have on its consolidated financial statements.

Receivables [Abstract]
Loans Held for Investment	(3) Loans Held for Investment The Company currently originates and acquires first mortgage and mezzanine loans secured by commercial properties. 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. During the three months ended March 31, 2019, the Company originated 11 loans with a total commitment of approximately $713.6 million, an initial unpaid principal balance of $633.1 million, and unfunded commitments at closing of $80.5 million. The following tables present an overview of the loan investment portfolio as of March 31, 2019 and December 31, 2018 (dollars in thousands): March 31, 2019 Loans Receivable Outstanding Principal Unamortized Premium (Discount), Loan Origination Fees, net Carrying Amount Senior loans $ 4,732,962 $ (20,828 ) $ 4,712,134 Subordinated and mezzanine loans — — — Subtotal before allowance 4,732,962 (20,828 ) 4,712,134 Allowance for loan losses — — — Total $ 4,732,962 $ (20,828 ) $ 4,712,134 December 31, 2018 Loans Receivable Outstanding Principal Unamortized Premium (Discount), Loan Origination Fees, net Carrying Amount Senior loans $ 4,313,591 $ (19,804 ) $ 4,293,787 Subordinated and mezzanine loans — — — Subtotal before allowance 4,313,591 (19,804 ) 4,293,787 Allowance for loan losses — — — Total $ 4,313,591 $ (19,804 ) $ 4,293,787 For the three months ended March 31, 2019, loan portfolio activity was as follows (dollars in thousands): Carrying Value Balance at December 31, 2018 $ 4,293,787 Additions during the period: Loans originated 628,460 Additional fundings 57,394 Amortization of discount and origination fees 3,628 Deductions during the period: Collection of principal (271,135 ) Balance at March 31, 2019 $ 4,712,134 At March 31, 2019 and December 31, 2018, there was no unamortized loan discount or premium included in loans held for investment at amortized cost on the consolidated balance sheets. The table below summarizes the carrying values and results of the Company’s internal risk rating review performed as of March 31, 2019 and December 31, 2018 (dollars in thousands): Carrying Value Rating March 31, 2019 December 31, 2018 1 $ — $ 29,923 2 1,161,728 959,314 3 3,416,582 3,099,401 4 133,824 205,149 5 — — Totals $ 4,712,134 $ 4,293,787 Weighted Average Risk Rating (1) 2.8 2.8 (1) Weighted Average Risk Rating calculated based on unpaid principal balance at period end. The weighted average risk rating at March 31, 2019 and December 31, 2018 was 2.8. During the three months ended March 31, 2019, three loans were moved from the Company’s Category 3 risk rating into its Category 2 risk rating, resulting from recent improvements in the operating performance of the underlying collateral. Additionally, during the three months ended March 31, 2019, the Company moved one loan from its Category 2 risk rating into its Category 3 risk rating based on the current operating performance of the underlying collateral. At March 31, 2019 and December 31, 2018, there were no loans on non-accrual status or that were impaired; thus, the Company did not record any allowance for loan losses.

The purchased CRE CLO investments consist of floating rate debt securities which, in the aggregate, had a weighted average coupon of LIBOR plus 2.2%. As of March 31, 2019 and December 31, 2018, the Company had 14 and four CMBS and CRE CLO investments, respectively, designated as available-for-sale securities. Details of the carrying and fair values of the Company’s CMBS and CRE CLO investment portfolio are as follows (dollars in thousands): March 31, 2019 Face Amount Unamortized Premium (Discount), net Gross Unrealized (Loss) Estimated Fair Value Investments, at Fair Value CMBS and CRE CLO Investments $ 310,192 $ (19 ) $ (1,879 ) $ 308,294 December 31, 2018 Face Amount Unamortized Premium (Discount), net Gross Unrealized (Loss) Estimated Fair Value Investments, at Fair Value CMBS and CRE CLO Investments $ 76,404 $ (38 ) $ (1,985 ) $ 74,381 CMBS and CRE CLO investment fair values are considered Level II fair value measurements within the fair value hierarchy of ASC 820-10. The CMBS and CRE CLO investment fair values are based upon market, broker, and counterparty or pricing services quotations, which provide valuation estimates, based upon reasonable market order indications. The Company reviews the fair value quotations, which are subject to significant variability based on market conditions such as interest rates, credit spreads and market liquidity, for reasonableness and consistency. The Company’s CMBS and CRE CLO investments have a weighted average contractual maturity, based on estimated fair value, of 16.3 years. The amortized cost and estimated fair value of the Company’s available-for-sale CMBS and CRE CLO investments by contractual maturity are shown in the following table (dollars in thousands): March 31, 2019 Amortized Cost Estimated Fair Value Maturity Date Within five years $ 37,920 $ 37,582 After five years 272,328 270,712 Total investment in CMBS and CRE CLO securities, at amortized cost and estimated fair value $ 310,248 $ 308,294 December 31, 2018 Amortized Cost Estimated Fair Value Maturity Date After one, within five years $ 37,929 $ 38,076 After five years 38,436 36,305 Total investment in CMBS and CRE CLO securities, at amortized cost and estimated fair value $ 76,365 $ 74,381 As of March 31, 2019, certain CMBS investments within the Company’s CMBS and CLO investment holdings were in an unrealized loss position. During the three months ended March 31, 2019 and year ended December 31, 2018, these CMBS investments traded at, or near, their carrying values, and interest and principal payments are current. Additionally, as of March 31, 2019, substantially all of the unrealized loss position relates to CMBS investments issued by a government sponsored enterprise. Currently, all of the underlying mortgage loans are performing. No other-than-temporary impairments were recognized through income during the three months ended March 31, 2019 or the year ended December 31, 2018.

The Company incurred approximately $8.7 million of issuance costs which are amortized on an effective yield basis over the shorter of the remaining life of the loans that collateralized the FL2 Notes, or the FL2 Notes. As of March 31, 2019, the Company’s unamortized issuance costs were $7.9 million. Interest expense on the outstanding FL2 Notes is payable monthly. For the three months ended March 31, 2019, interest expense (excluding amortization of deferred financing costs) of $7.7 million is included in the Company’s consolidated statements of income and comprehensive income. As of March 31, 2019, FL2 Mortgage Assets represented 21.1% of the aggregate unpaid principal balance of the Company’s loan investment portfolio and had an aggregate principal balance of approximately $993.6 million. On February 14, 2018 (the “FL1 Closing Date”), the Sub-REIT entered into a collateralized loan obligation (“TRTX 2018-FL1”) through its wholly-owned subsidiaries TPG Real Estate Finance 2018-FL1 Issuer, Ltd., an exempted company incorporated in the Cayman Islands with limited liability, as issuer (the “FL1 Issuer”), and TPG RE Finance Trust 2018-FL1 Co-Issuer, LLC, a Delaware limited liability company, as co-issuer (the “FL1 Co-Issuer” and together with the FL1 Issuer, the “FL1 Issuers”).

Additionally, the Company holds as an investment $12.4 million (principal amount) of FL1 Notes, of which $9.9 million were purchased during the three months ended March 31, 2019. Proceeds from the issuance of the FL1 Securities were used by the FL1 Issuers to purchase one commercial real estate whole loan (the “FL1 Whole Loan”) and 25 fully-funded pari passu Pari Passu The Company incurred approximately $9.8 million of issuance costs which are amortized on an effective yield basis over the shorter of the remaining life of the loans that collateralized the FL1 Notes, or the FL1 Notes. As of March 31, 2019, the Company’s unamortized issuance costs were $2.3 million. Interest expense on the outstanding FL1 Notes is payable monthly. For the three months ended March 31, 2019, interest expense (excluding amortization of deferred financing costs) of $5.4 million is included in the Company’s consolidated statements of income and comprehensive income.

In accordance with ASC 810, the Company evaluated the key attributes of the FL2 Issuers and the FL1 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 FL2 Issuers and FL1 Issuers were VIEs and that the Company was the primary beneficiary. The Company is the primary beneficiary of the VIEs because it has the ability to control the most significant activities of the FL2 Issuers and the FL1 Issuers, the obligation to absorb losses, and the right to receive benefits, that could potentially be significant to these entities. As a result, the Company consolidates the FL2 Issuers and FL1 Issuers. The Company’s total assets and total liabilities as of March 31, 2019 and December 31, 2018 included the following VIE assets and liabilities of TRTX 2018-FL2 and TRTX 2018-FL1 (dollars in thousands): March 31, 2019 December 31, 2018 ASSETS Cash and Cash Equivalents $ 1,032 $ 3,896 Accounts Receivable from Servicer/Trustee 6,562 94,763 Accrued Interest Receivable 3,130 3,672 Loans Held for Investment 1,678,629 1,824,281 Total Assets $ 1,689,353 $ 1,926,612 LIABILITIES Accrued Interest Payable $ (2,632 ) $ (2,637 ) Accrued Expenses (619 ) (668 ) Collateralized Loan Obligations (1,283,520 ) (1,514,790 ) Total Liabilities $ (1,286,771 ) $ (1,518,095 ) The following table outlines TRTX 2018-FL2 and TRTX 2018-FL1 loan collateral and borrowings under the TRTX 2018-FL2 and TRTX 2018-FL1 collateralized loan obligations as of March 31, 2019 and December 31, 2018 (dollars in thousands): As of March 31, 2019 Collateral (loan investments) Debt (notes issued) Outstanding Principal Carrying Value Face Value Carrying Value $ 1,678,629 $ 1,678,629 $ (1,261,554 ) $ (1,251,393 ) As of December 31, 2018 Collateral (loan investments) Debt (notes issued) Outstanding Principal Carrying Value Face Value Carrying Value $ 1,824,281 $ 1,824,281 $ (1,527,237 ) $ (1,514,790 ) Assets held by the FL2 Issuers and the FL1 Issuers are restricted and can only be used to settle obligations of the related VIE.

(3) Borrowings under the secured credit agreement with a guarantee for 100% recourse. Asset-Specific Financing As of March 31, 2019 and December 31, 2018, the Company had one asset-specific financing arrangement to finance certain of its lending activities. The borrowing allows for additional advances up to a specified cap and is secured by one loan held for investment. Holdco has delivered a payment guarantee in favor of BMO Harris, the lender, as additional credit support for the financing. The liability of Holdco under this guarantee is generally capped at 25% of the outstanding obligations of the special purpose subsidiary which is the primary obligor under the financing. In addition, Holdco has delivered a non-recourse carveout guarantee, which can trigger recourse to Holdco as a result of certain “bad boy” defaults for losses incurred by BMO Harris or the entire outstanding obligations of the financing borrower, depending on the nature of the “bad boy” default in question. The asset specific financing at March 31, 2019 and December 31, 2018 is guaranteed by Holdco, and the agreement includes guarantor covenants regarding liquid assets and net worth requirements. The Company was in compliance with all covenants as of March 31, 2019 and December 31, 2018. Secured Revolving Repurchase Agreements The Company frequently utilizes secured revolving repurchase agreements to finance the direct origination or acquisition of commercial real estate mortgage loans, and CMBS and CRE CLO investments. Under these secured revolving repurchase agreements, the Company transfers all of its rights, title and interest in the loans, CMBS and CRE CLO investments 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 collects all principal and interest on related loans or CMBS and CRE CLO investments and remits to the Company only the net after collecting its interest and other fees. The loan and CMBS and CRE CLO investment related secured revolving repurchase agreements are 25% and 100% recourse to Holdco, respectively. At March 31, 2019 and December 31, 2018, the Company had five secured revolving repurchase agreements to finance its loan investing activities. Credit spreads vary depending upon the collateral type and advance rate. Assets pledged at March 31, 2019 and December 31, 2018 consisted of 53 and 51 mortgage loans, or participation interests therein, respectively. The Company’s secured revolving repurchase agreements secured by commercial mortgage loans are considered long-term borrowings. At March 31, 2019 and December 31, 2018, the Company had four and two secured revolving repurchase agreements to finance its CMBS and CRE CLO investment activities. Credit spreads vary depending upon the collateral type and advance rate. CMBS and CRE CLO investments pledged consisted of 10 CRE CLO investments and two CMBS investments at March 31, 2019 and two CMBS investments at December 31, 2018. The Company’s secured revolving repurchase agreements secured by CMBS and CRE CLO investments are considered short-term borrowings.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(8) 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, 2019, the Company had $52.3 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-FL1 and TRTX 2018-FL2 (collateralized loan obligations as of March 31, 2019 and December 31, 2018), and secured financing arrangements 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. The Company did not have any non-recurring fair value items as of March 31, 2019 and December 31, 2018. The following tables provide information about financial assets and liabilities not carried at fair value on a recurring basis in our consolidated balance sheet (dollars in thousands): March 31, 2019 Fair Value Carrying Value Level I Level II Level III Financial Assets Loans Held for Investment $ 4,712,134 — — $ 4,741,978 Financial Liabilities Term Loan Facility 266,549 — — 266,549 Collateralized Loan Obligations 1,251,393 — — 1,251,393 Secured Financing Arrangements 2,097,844 — — 2,097,844 December 31, 2018 Fair Value Carrying Value Level I Level II Level III Financial Assets Loans Held for Investment $ 4,293,787 — — $ 4,317,844 Financial Liabilities Term Loan Facility 113,504 — — 113,504 Collateralized Loan Obligations 1,509,930 — — 1,509,930 Secured Financing Arrangements 1,526,449 — — 1,526,449 Level III fair values were determined based on standardized valuation models and significant unobservable market inputs, including holding period, discount rates based on loan to value, property type and loan pricing expectations developed by the Manager that were corroborated with other institutional lenders to determine a market spread that was added to the one-month LIBOR forward curve. There were no transfers of financial assets or liabilities within the fair value hierarchy during the three months ended March 31, 2019 or December 31, 2018. At March 31, 2019 and December 31, 2018, the estimated fair value of Loans Held for Investment was $4.7 billion and $4.3 billion, respectively. The weighted average gross spread at March 31, 2019 and December 31, 2018 was 3.9% and 3.9%, respectively. The weighted average years to maturity at March 31, 2019 and December 31, 2018 was 3.8 years and 3.9 years, respectively, assuming full extension of all loans. At March 31, 2019 and December 31, 2018, the carrying value of the secured financing agreements approximates fair value as current borrowing spreads reflect market terms. At March 31, 2019 and December 31, 2018, the carrying value of the assets and liabilities of TRTX 2018-FL1 and TRTX 2018-FL2 approximates fair value as current borrowing spreads reflect market terms.

Income Taxes	(9) Income Taxes The Company indirectly owns 100% of the equity of multiple taxable REIT subsidiaries (collectively “TRSs”), including certain of its TRTX 2018-FL1 and TRTX 2018-FL2 subsidiaries. Taxable REIT subsidiaries 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 regulatory agencies until the related statute of limitations expires, with open tax years for all years since the Company’s initial capitalization in 2014. The years open to examination generally range from 2015 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, 2019 and December 31, 2018, based on the Company’s evaluation, there is no reserve for any 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 and comprehensive income. For the three months ended March 31, 2019 and 2018, the Company did not have interest or penalties associated with the underpayment of any income taxes. For the three months ended March 31, 2019 and 2018, the Company incurred no federal, state and local tax expense relating to its TRSs. For the three months ended March 31, 2019 and 2018, the Company recognized $0.2 million of federal, state and local tax expense. At March 31, 2019 and 2018, the Company’s effective tax rate was 0.8%. At March 31, 2019 and December 31, 2018, the Company had no deferred tax assets or liabilities.

Related Party Transactions [Abstract]
Related Party Transactions	(10) Related Party Transactions Management Agreement The Company is externally managed and advised by the Manager pursuant to the terms of a management agreement, dated July 25, 2017, between the Company and the Manager (as amended, the “Management Agreement”). On May 2, 2018, the Company and the Manager amended the Management Agreement solely for the purpose of amending the definitions of “Equity,” “Core Earnings” and “Incentive Compensation” in the Management Agreement. The changes were effected to include equity issued by subsidiaries of the Company in the definition of Equity, and to exclude distributions on equity issued by subsidiaries from the calculation of the Manager’s Incentive Compensation. 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) and 1.50% per annum (0.375% per quarter) of the Company’s “Equity.” The base management fee is payable in cash, quarterly in arrears. As amended, “Equity” means (a) the sum of (1) the net proceeds received by the Company and, without duplication, the Company’s subsidiaries, from all issuances of the Company’s and the subsidiaries’ equity securities, including for the avoidance of doubt issuances of common stock and Class A common stock by the Company prior to the completion of the Company’s initial public offering (for purposes of calculating this amount, the net proceeds received by the Company from all issuances of the Company’s outstanding common stock and Class A common stock prior to the completion of the Company’s initial public offering equals approximately $1.0 billion), plus (2) the value of contributions, including, without limitation, contributions of assets or interests in assets in exchange for equity securities, made by persons other than the Company or a subsidiary of the Company, from time to time, to the capital of the Company or another subsidiary of the Company plus (3) the Company’s cumulative Core Earnings for the period commencing on the completion of the Company’s initial public offering to the end of the most recently completed calendar quarter, and (b) less (1) any distributions made by the Company to the holders of the Company’s equity securities and any distributions made by the Company’s subsidiaries to the holders of the subsidiaries’ equity securities (other than to the Company or another subsidiary of the Company) following the completion of the Company’s initial public offering, (2) any amount that the Company or any of the Company’s subsidiaries has paid to repurchase for cash the Company’s common stock or Class A common stock following the completion of the Company’s initial public offering and (3) any Incentive Compensation earned by the Manager following the completion of the Company’s initial public offering. With respect to that portion of the period from and after the completion of the Company’s initial public offering that is used in the calculation of Incentive Compensation or the base management fee, all items in the foregoing sentence (other than the Company’s cumulative Core Earnings) will be calculated on a daily weighted average basis. The Manager is entitled to incentive compensation which is calculated and payable in cash with respect to each calendar quarter following the completion of the Company’s initial public offering (or part thereof that the Management Agreement is in effect) 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 (or such lesser number of completed calendar quarters, if applicable), 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 (or such lesser number of completed calendar quarters, if applicable), 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 (or such lesser number of completed calendar quarters preceding the applicable period, if applicable). 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 (or such lesser number of completed calendar quarters following the completion of the Company’s initial public offering) 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. As amended, “Core Earnings” 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 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. The Company is required to reimburse the Manager or its affiliates for documented costs and expenses incurred by it and its affiliates on the Company’s behalf except those specifically required to be borne by the Manager or its affiliates under the Management Agreement. The Company’s reimbursement obligation is not subject to any dollar limitation. The Manager or its affiliates is responsible for, and the Company will not reimburse the Manager or its affiliates for, the expenses related to the personnel of the Manager and its affiliates who provide services to the Company. However, the Company will reimburse the Manager for 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. Management Fees Incurred and Paid for the three months ended March 31, 2019 and March 31, 2018 For the three months ended March 31, 2019 and 2018, 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, 2019 2018 Management Agreement fees incurred $ 6,508 $ 5,630 Management Agreement fees paid 6,100 5,232 Management fees and incentive management fees included in payable to affiliates on the consolidated balance sheets at March 31, 2019 and December 31, 2018 are $6.5 million and $6.1 million, respectively. The Company is responsible for reimbursing the Manager for certain expenses paid by the Manager on behalf of the Company or for certain services provided by the Manager to the Company. Expenses incurred by the Manager and reimbursed by the Company are reflected in the respective consolidated statements of income and comprehensive income expense category or the consolidated balance sheets based on the nature of the item. For the three months ended March 31, 2019, the Manager incurred $0.3 million of expenses that were reimbursable by the Company. As of March 31, 2019, no amounts remained outstanding that were reimbursable by the Company to the Manager. For the three months ended March 31, 2018, $0.3 million was incurred by the Manager and reimbursable by the Company. On March 19, 2019, in conjunction with the Company’s common stock offering of 6 million shares, the Manager reimbursed offering costs of $0.3 million. See Note 12 to the Consolidated Financial Statements for details.

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 or, if such termination occurs prior to July 25, 2019, and such termination fee is payable, the base management fees and the incentive compensation will be annualized for the period from July 25, 2017 to July 25, 2019 based on such fees actually received by the Manager during such period.

Earnings Per Share [Abstract]
Earnings per Share	(11) Earnings per Share The Company calculates its basic and diluted earnings per share using the two-class method for all periods presented, as 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, including participating in any dividends, and therefore have been included in the Company’s basic and diluted earnings per share calculation. For the three months ended March 31, 2019 and 2018, $0.1 million and $0.03 million, respectively of common stock dividends declared and undistributed net income attributable to common stockholders were allocated to unvested shares of our common stock pursuant to stock grants made under the Company’s Incentive Plan (see Note 13 for details). The following table sets forth the calculation of basic and diluted earnings per common share (common stock and Class A common stock) based on the weighted-average number of shares of common stock and Class A common stock outstanding (in thousands, except share and per share data): Three Months Ended March 31, 2019 2018 Net Income Attributable to TPG RE Finance Trust, Inc. $ 28,409 $ 25,111 Participating Securities' Share in Earnings (141 ) — Net Income Attributable to Common Stockholders $ 28,268 $ 25,111 Weighted Average Common Shares Outstanding, Basic and Diluted 68,294,736 60,393,818 Per Common Share Amount, Basic and Diluted $ 0.42 $ 0.42

Stockholders Equity Note [Abstract]
Stockholders' Equity	(12) Stockholders’ Equity 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, $0.001 par value per share, 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. 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, 2019, no shares of common stock were sold pursuant to the equity distribution agreement. Common Stock Issuance On March 19, 2019, the Company completed a common stock offering of 6.0 million shares at a price to the underwriters of $19.80 per share, generating net proceeds of $118.8 million, after underwriting discounts. The Manager reimbursed offering costs of $0.3 million. The Company intends to use the proceeds from the offering to originate or acquire commercial mortgage loans consistent with its investment strategy and investment guidelines. 10b5-1 Purchase Plan The Company entered into an agreement and related amendments (the “10b5-1 Purchase Plan”) with Goldman Sachs & Co. LLC, as our agent, to buy in the open market up to $35.0 million in shares of our common stock in the aggregate during the period beginning on or about August 21, 2017 and ending 12 months thereafter or, if sooner, the date on which all the capital committed has been exhausted. On August 1, 2018, the Company’s Board of Directors authorized the Company to extend the repurchase period for the remaining capital committed to the 10b5-1 Purchase Plan. No other changes to the terms of the 10b5-1 Purchase Plan were authorized. Under the amended 10b5-1 Purchase Plan, the repurchase period was extended to February 28, 2019 or, if sooner, the date on which all the capital committed to the 10b5-1 Purchase Plan has been exhausted. The 10b5-1 Purchase Plan requires Goldman Sachs & Co. LLC to purchase for us shares of our common stock when the market price per share is below the threshold price specified in the 10b5-1 Purchase Plan which is based on our book value per common share. During the three months ended March 31, 2019, the Company repurchased 2,324 shares of common stock, at a weighted average price of $18.27 per share, for total consideration (including commissions and related fees) of $0.04 million. The 10b5-1 Purchase Plan expired by its terms on February 28, 2019. Dividends Upon the approval of the Company’s Board of Directors, dividends are accrued by the Company. 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, and then to the holders of the Company’s common stock and Class A 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. Preferred Stock During the three months ended March 31, 2019, a subsidiary of the Company issued 125 shares of Series A preferred stock for proceeds of $0.1 million.

Common and Class A Common Stock On March 19, 2019, the Company’s Board of Directors declared a dividend for the first quarter of 2019 in the amount of $0.43 per share of common stock and Class A common stock, or $31.6 million in the aggregate, which dividend was payable on April 25, 2019 to holders of record of our common stock and Class A common stock as of March 29, 2019. On March 19, 2018, the Company declared a dividend for the first quarter of 2018 in the amount of $0.42 per share of common stock and Class A common stock, or $25.3 million in the aggregate, which was paid on April 25, 2018 to holders of record of our common stock and Class A common stock as of March 29, 2018. For the three months ended March 31, 2019 and 2018, common stock and Class A common stock dividends in the amount of $31.6 million and $25.3 million were declared and approved, respectively.

The Incentive Plan provides for the grant of equity-based awards to the Company’s, and its affiliates’, directors, officers, employees (if any) and consultants, and the members, officers, directors, employees and consultants of our Manager or its affiliates, as well as to our Manager and other entities that provide services to us and our affiliates and the employees of such entities. The total number of shares of common stock or long term incentive plan (“LTIP”) units that may be awarded under the Incentive Plan is 4,600,463. The Incentive Plan will automatically expire on the tenth anniversary of its effective date, unless terminated earlier by the Company’s Board of Directors. Generally, the shares vest in installments over a four-year period, pursuant to the terms of the award and the Incentive Plan. As of March 31, 2019, there were 327,901 shares of common stock that will vest as follows: 100,305 shares in 2019; 93,876 shares in 2020; 93,877 shares in 2021; and 39,843 shares in 2022.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
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.
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: impairment; adequacy of provisions for loan losses; and valuation of financial instruments.
Principles of Consolidation	Principles of Consolidation Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810—Consolidation (“ASC 810”) provides guidance on the identification of a VIE (a variable interest entity for which control is achieved through means other than voting rights) and the determination of which business enterprise, if any, should consolidate the VIE. An entity is considered a VIE if any of the following applies: (1) the equity investors (if any) lack one or more of the essential characteristics of a controlling financial interest; (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support; or (3) the equity investors have voting rights that are not proportionate to their economic interests and the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest. The Company consolidates VIEs in which it is considered to be the primary beneficiary. The primary beneficiary is defined as the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance; and (2) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE. At each reporting date, the Company reconsiders its primary beneficiary conclusion 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 accordingly (see Note 5 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 credit impairment, 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 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. 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. The Company considers a loan to be non-performing and places the loan on non-accrual status when: (1) management determines the borrower is incapable of, or has ceased efforts toward, curing the cause of a default; (2) the loan becomes 90 days delinquent; or (3) the loan experiences a maturity default. 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 principal and 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. During the three months ended March 31, 2019 and the year end December 31, 2018, no loans were placed on non-accrual status and no losses or impairments were recorded to our loan portfolio.
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 any premiums, discounts, loan origination fees and loan loss allowances, if any. 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. The Company evaluates each loan classified as a loan held for investment for impairment on a quarterly basis. Impairment occurs when it is deemed probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan. If the loan is considered to be impaired, a loan loss allowance is recorded to reduce the carrying value of the loan to the present value of the expected future cash flows discounted at the loan’s contractual effective rate, or the fair value of the collateral securing the impaired loan, less estimated costs to sell such collateral, if recovery of the Company’s investment is expected solely from the sale of such collateral. As part of the quarterly impairment review, the Company evaluates the risk of each loan and assigns a risk rating based on a variety of factors, grouped as follows to include, among other factors: (i) loan and credit structure, including the as-is loan-to-value (“LTV”) and structural features; (ii) quality and stability of real estate value and operating cash flow, including debt yield, property type, dynamics of the geographic, 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- Risk of Impairment/Default—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. Since Inception, the Company has not recognized any impairments on its loan portfolio and has not recorded any loan loss allowances against any of the loans in its portfolio. The Company’s determination of asset-specific loan loss reserves, should any such reserves be necessary, relies on material estimates regarding the fair value of loan collateral. Such losses could be caused by various factors, including, but not limited to, unanticipated adverse changes in the economy or events adversely affecting specific assets, borrowers, industries in which our borrowers operate or markets in which our borrowers or their properties are located. Significant judgment is required when evaluating loans for impairment. The Company’s loans are typically collateralized by real estate, or in the case of mezzanine loans, by a partnership or similar equity interest in an entity that owns real estate. As a result, the Company regularly evaluates on a loan-by-loan basis the extent and impact of any credit deterioration associated with the performance and/or value of the underlying collateral property as well as 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 impairment analyses are completed and reviewed by asset management personnel and evaluated by senior management, who utilize various data sources, including (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.
Commercial Mortgage-Backed and Commercial Real Estate Collateralized Loan Obligation Securities	Commercial Mortgage-Backed and Commercial Real Estate Collateralized Loan Obligation Securities The Company acquires CMBS and CRE CLO investments primarily for cash management purposes, and also for investment purposes. The Company designates CMBS and CRE CLO investments as available-for-sale on the acquisition date. CMBS and CRE CLO investments that are classified as available-for-sale are recorded at fair value through other comprehensive income (loss) in the Company’s consolidated financial statements. Additionally, CMBS and CRE CLO investments that are not classified as held-to-maturity and which the Company does not hold for the purpose of selling in the near-term, but may dispose of prior to maturity, are also designated as available-for-sale and are carried at fair value. The Company’s recognition of interest income from its CMBS and CRE CLO investments, including its amortization of premium and discount, follows the Company’s revenue recognition policy as described under “Revenue Recognition” above. The Company uses a specific identification method when determining the cost of a security sold and the amount of unrealized gain or loss reclassified from accumulated other comprehensive income (loss) into earnings. Unrealized losses on securities that, in the judgment of management, are other than temporary are charged against earnings as a loss in the consolidated statements of income and comprehensive income. Significant valuation inputs are Level II in the fair value hierarchy as described below under “Fair Value Measurements”.
Portfolio Financing Arrangements	Portfolio Financing Arrangements The Company finances certain loan and CMBS and CRE CLO investments using secured revolving repurchase agreements, asset-specific financing arrangements, senior secured and secured credit agreements, collateralized loan obligations, and a term loan facility. 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 and comprehensive income. 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, 2019, the Company has transferred 100% of the senior mortgage loan that the Company originated on a non-recourse basis to a third-party lender and has 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 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, and not the non-consolidated senior loan interest sold or co-originated that the Company transferred. As of December 31, 2018, the Company revised its “Note Payable” naming convention in its consolidated balance sheet to “Asset-Specific Financings”. No amounts reported in prior periods were reclassified between financial statement line items and there was no impact to the Company’s financial statements resulting from this naming convention change during the current fiscal year.
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.
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. 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
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 and diluted earnings per common share is computed by dividing net income attributable to common stockholders (i.e., holders of common stock and Class A common stock), by the weighted-average number of common shares (both common stock and 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 are identical to the common stock, except (1) the Class A common stock is 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 may not be listed on a national securities exchange or a national market system and (2) each share of Class A common stock is 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. The Class A common stock votes together with the common stock as a single class. Shares of Class A common stock have been issued to, and are owned by, TPG RE Finance Trust Management, L.P., a Delaware limited partnership (the “Manager”), and certain individuals or entities who are or were affiliated with the Manager, and the sale or conversion to common stock by investors of such shares of Class A common stock is subject to certain restrictions. Diluted earnings per common share is calculated by including the effect of dilutive securities. The Company accounts for unvested share-based payment awards that contain non-forfeitable dividend rights or dividend equivalents (whether paid or unpaid) as participating securities, which are included in the computation of earnings per share pursuant to the two-class method.
Share-Based Compensation	Share-Based Compensation Share-based compensation consists of awards issued by the Company to certain employees of affiliates of our Manager and certain members of our Board of Directors. These share-based awards generally vest in installments over a fixed period of time. Compensation expense is recognized in net income on a straight-line basis over the applicable awards’ 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 and secured financing arrangements 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 over the life of the related obligations.
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, 2019 and December 31, 2018. The balances in these accounts may exceed the insured limits.
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.
Accounts Receivable from Servicer/Trustee	Accounts Receivable from Servicer/Trustee Accounts receivable from Servicer/Trustee represents cash proceeds from loan and CMBS and CRE CLO investment activities that have not been remitted to the Company based on contractual procedures previously agreed upon. Amounts are generally held by the Servicer/Trustee for less than 60 days before being remitted to the Company.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 will replace the “incurred loss” model under existing guidance with an “expected loss” model for instruments measured at amortized cost, and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. Upon adoption, and resulting from this change, the Company expects that it will be required to record a loan loss reserve at origination or acquisition of an individual loan or a loan portfolio. ASU 2016-13 also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 and is to be adopted through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently evaluating the impact ASU 2016-13 will have on its consolidated financial statements.

Incentive management fee, description				The Manager is entitled to incentive compensation which is calculated and payable in cash with respect to each calendar quarter following the completion of the Company’s initial public offering (or part thereof that the Management Agreement is in effect) 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 (or such lesser number of completed calendar quarters, if applicable), 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 (or such lesser number of completed calendar quarters, if applicable), 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 (or such lesser number of completed calendar quarters preceding the applicable period, if applicable). 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 (or such lesser number of completed calendar quarters following the completion of the Company’s initial public offering) 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.
