Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Business Terra Property Trust, Inc. (and, together with its consolidated subsidiaries, the “Company” or “Terra Property Trust”) was incorporated under the general corporation laws of the State of Maryland on December 31, 2015. Terra Property Trust is a real estate credit focused company that originates, structures, funds and manages commercial real estate investments, including mezzanine loans, first mortgage loans, subordinated mortgage loans and preferred equity investments. The Company’s loans finance the acquisition, construction, development or redevelopment of quality commercial real estate in the United States. The Company focuses on the origination of middle market loans in the approximately $10 million to $50 million range, to finance properties in primary and secondary markets. The Company believes these loans are subject to less competition and offer higher risk adjusted returns than larger loans with similar risk/return metrics. On January 1, 2016, Terra Secured Income Fund 5, LLC (“Terra Fund 5”), the Company’s then parent, contributed its consolidated portfolio of net assets to the Company pursuant to a contribution agreement in exchange for shares of the Company’s common stock. Upon receipt of the contribution of the consolidated portfolio of net assets from Terra Fund 5, the Company commenced its operations on January 1, 2016. On March 2, 2020, the Company engaged in a series of transactions pursuant to which the Company issued an aggregate of 4,574,470.35 shares of our common stock in exchange for the settlement of an aggregate of $49.8 million of participation interests in loans held by the Company, cash of $25.5 million and other working capital. As of September 30, 2020, Terra JV, LLC (“Terra JV”) held 87.4% of the issued and outstanding shares of the Company's common stock with the remainder held by Terra Offshore Funds ( Note 3 ). The Company has elected to be taxed, and to qualify annually thereafter, as a real estate investment trust (“REIT”) under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), commencing with the taxable year ended December 31, 2016. As a REIT, the Company is not subject to federal income taxes on income and gains distributed to the stockholders as long as certain requirements are satisfied, principally relating to the nature of income and the level of distributions, as well as other factors. The Company also operates its business in a manner that permits it to maintain its exclusion from registration under the Investment Company Act of 1940, as amended. The Company’s investment activities are externally managed by Terra REIT Advisors, LLC (“Terra REIT Advisors” or the “Manager”), a subsidiary of the Company’s sponsor, Terra Capital Partners, LLC, pursuant to a management agreement (the “Management Agreement”), under the oversight of the Company’s board of directors ( Note 7 ). The Company does not currently have any employees and does not expect to have any employees. Services necessary for the Company’s business are provided by individuals who are employees of the Manager or by individuals who were contracted by the Company or by the Manager to work on behalf of the Company pursuant to the terms of the Management Agreement.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The interim consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and include all of the Company’s accounts and those of its consolidated subsidiaries. The accompanying interim financial statements of the Company and related financial information have been prepared pursuant to the requirements for reporting on Form 10-Q and Articles 6 or 10 of Regulation S-X. All intercompany balances and transactions have been eliminated. Loans Held for Investment The Company originates, acquires, and structures real estate-related loans generally to be held to maturity. Loans held for investment are carried at the principal amount outstanding, adjusted for the accretion of discounts on investments and exit fees, and the amortization of premiums on investments and origination fees. The Company’s preferred equity investments, which are economically similar to mezzanine loans and subordinate to any loans but senior to common equity, are accounted for as loans held for investment. Loans are carried at cost less allowance for loan losses. Allowance for Loan Losses The Company’s loans are typically collateralized by either the sponsors’ equity interest in the real estate properties or the underlying real estate properties. As a result, the Company regularly evaluates the extent and impact of any credit migration associated with the performance and/or value of the underlying collateral property as well as the financial and operating capability of the borrower/sponsor on a loan-by-loan basis. Specifically, a property’s operating results and any cash reserves are analyzed and used to assess (i) whether cash from operations and/or reserve balances are sufficient to cover the debt service requirements currently and into the future; (ii) the ability of the borrower to refinance the loan; and/or (iii) the property’s liquidation value. The Company also evaluates the financial wherewithal of the sponsor as well as its competency in managing and operating the real estate property. 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 and finance personnel, who utilize various data sources, including (i) periodic financial data such as debt service coverage ratio, property occupancy, tenant profile, rental rates, operating expenses, the borrower’s exit plan, the capitalization and discount rates; (ii) site inspections; and (iii) current credit spreads and discussions with market participants. The Manager performs a quarterly evaluation for possible impairment of the Company’s portfolio of loans. A loan is impaired if it is deemed probable that the Company will not be able to collect all amounts due according to the contractual terms of the loan. Impairment is measured based on the present value of expected future cash flows or the fair value of the collateral, if the loan is collateral dependent. Upon measurement of impairment, the Company records an allowance to reduce the carrying value of the loan with a corresponding charge to net income. In conjunction with the quarterly evaluation of loans not considered impaired, the Manager assesses the risk factors of each loan and assigns each loan a risk rating between 1 and 5, which is an average of the numerical ratings in the following categories: (i) sponsor capability and financial condition; (ii) loan and collateral performance relative to underwriting; (iii) quality and stability of collateral cash flows and/or reserve balances; and (iv) loan to value. Based on a 5-point scale, the Company’s loans are rated “1” through “5”, from less risk to greater risk, as follows: Risk Rating Description 1 Very low risk 2 Low risk 3 Moderate/average risk 4 Higher risk 5 Highest risk The Company records an allowance for loan losses equal to (i) 1.5% of the aggregate carrying amount of loans rated as a “4”, plus (ii) 5% of the aggregate carrying amount of loans rated as a “5”, plus (iii) impaired loan reserves, if any. There may be circumstances where the Company modifies a loan by granting the borrower a concession that it might not otherwise consider when a borrower is experiencing financial difficulty or is expected to experience financial difficulty in the foreseeable future. Such concessionary modifications are classified as troubled debt restructurings (“TDR”s) unless the modification solely results in a delay in a payment that is insignificant. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes. Marketable Securities The Company from time to time invests in short term debt and equity securities. These securities are classified as available-for-sale and are carried at fair value. Changes in the fair value of equity securities are recognized in earnings. Changes in the fair value of debt securities are reported in other comprehensive income until a gain or loss on the securities is realized. Real Estate Owned, Net Real estate acquired is recorded at its estimated fair value at acquisition and is shown net of accumulated depreciation and impairment charges. Acquisition of properties generally are accounted for as asset acquisitions. Under asset acquisition accounting, the costs to acquire real estate, including transaction costs, are accumulated and then allocated to individual assets and liabilities acquired based upon their relative fair value. The Company allocates the purchase price of its real estate acquisitions to land, building, tenant improvements, acquired in-place leases, intangibles for the value of any above or below market leases at fair value and to any other identified intangible assets or liabilities. The Company amortizes the value allocated to in-place leases over the remaining lease term, which is reported in depreciation and amortization expense on its consolidated statements of operations. The value allocated to above or below market leases are amortized over the remaining lease term as an adjustment to rental income. Real estate assets are depreciated using the straight-line method over their estimated useful lives: buildings and improvements - not to exceed 40 years, and tenant improvements - shorter of the lease term or life of the asset. Ordinary repairs and maintenance which are not reimbursed by the tenants are expensed as incurred. Major replacements and betterments which improve or extend the life of the asset are capitalized and depreciated over their estimated useful life. Management reviews the Company’s real estate for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The review of recoverability is based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate assets. If impaired, the real estate asset will be written down to its estimated fair value. Leases The Company determines if an arrangement is a lease at inception. Operating leases in which the Company is the lessee are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s lease typically does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made in advance and excludes lease incentives if there were any. The Company’s lease term may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Revenue Recognition Revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Interest Income: Interest income is accrued based upon the outstanding principal amount and contractual terms of the loans and preferred equity investments that the Company expects to collect and it is accrued and recorded on a daily basis. Discounts and premiums on investments purchased are accreted or amortized over the expected life of the respective loan using the effective yield method, and are included in interest income in the consolidated statements of operations. Loan origination fees and exit fees, net of portions attributable to obligations under participation agreements, are capitalized and amortized or accreted to interest income over the life of the investment using the effective yield method. Income accrual is generally suspended for loans at the earlier of the date at which payments become 90 days past due or when, in the opinion of the Manager, recovery of income and principal becomes doubtful. Outstanding interest receivable is assessed for recoverability. Interest is then recorded on the basis of cash received until accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. The Company holds loans in its portfolio that contain paid-in-kind (“PIK”) interest provisions. The PIK interest, which represents contractually deferred interest that is added to the principal balance that is due at maturity, is recorded on the accrual basis. Real Estate Operating Revenues: Real estate operating revenue is derived from leasing of space to various types of tenants. The leases are for fixed terms of varying length and generally provide for annual rent increases and expense reimbursements to be paid in monthly installments. Lease revenue, or rental income from leases, is recognized on a straight-line basis over the term of the respective leases. Additionally, the Company recorded above- and below-market lease intangibles, which are included in real estate owned, net, in connection with the acquisition of the real estate properties. These intangible assets and liabilities are amortized to lease revenue over the remaining contractual lease term. Other Revenues: Prepayment fee income is recognized as prepayments occur. All other income is recognized when earned. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments, with original maturities of ninety days or less when purchased, as cash equivalents. Cash and cash equivalents are exposed to concentrations of credit risk. The Company maintains all of its cash at financial institutions which, at times, may exceed the amount insured by the Federal Deposit Insurance Corporation. Restricted cash represents cash held as additional collateral by the Company on behalf of the borrowers related to the investments in loans or preferred equity instruments for the purpose of such borrowers making interest and property-related operating payments. Restricted cash is not available for general corporate purposes. The related liability is recorded in “ Interest reserve and other deposits held on investments ” on the consolidated balance sheets. Cash held in escrow by lender represents amounts funded to an escrow account for debt services and tenant improvements. The following table provides a reconciliation of cash, cash equivalents and restricted cash in the Company’s consolidated balance sheets to the total amount shown in its consolidated statements of cash flows: September 30, 2020 September 30, 2019 Cash and cash equivalents $ 65,729,695 $ 36,360,811 Restricted cash 26,017,300 22,530,675 Cash held in escrow by lender 1,864,351 1,794,653 Total cash, cash equivalents and restricted cash shown in the consolidated $ 93,611,346 $ 60,686,139 Participation Interests Loan participations from the Company which do not qualify for sale treatment remain on the Company’s consolidated balance sheets and the proceeds are recorded as obligations under participation agreements. For the investments for which participation has been granted, the interest earned on the entire loan balance is recorded within “ Interest income ” and the interest related to the participation interest is recorded within “ Interest expense from obligations under participation agreements ” in the consolidated statements of operations. Interest expense from obligations under participation agreement is reversed when recovery of interest income on the related loan becomes doubtful. See “ Obligations under Participation Agreements ” in Note 8 for additional information. Term Loan The Company finances certain of its senior loans through borrowings under an indenture and credit agreement. The Company accounts for the borrowings as a term loan, which is carried at the contractual amount (cost), net of unamortized deferred financing fees. Repurchase Agreement The Company financed certain of its senior loans through repurchase transactions under a master repurchase agreement. The Company accounted for the repurchase transactions as secured borrowing transactions, which are carried at their contractual amounts (cost), net of unamortized deferred financing fees. Fair Value Measurements U.S. GAAP establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The Company has not elected the fair value option for its financial instruments, including loans held for investment, loans held for investment acquired through participation, obligations under participation agreements, mortgage loan payable, repurchase agreement payable and revolving credit facility payable. Such financial instruments are carried at cost, less impairment, where applicable. Marketable securities are financial instruments that are reported at fair value. Deferred Financing Costs Deferred financing costs represent fees and expenses incurred in connection with obtaining financing for investments. These costs are presented in the consolidated balance sheets as a direct deduction of the debt liability to which the costs pertain. These costs are amortized using the effective interest method and are included in interest expense on the applicable borrowings in the consolidated statements of operations over the life of the borrowings. Income Taxes The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code commencing with the taxable year ended December 31, 2016. In order to qualify as a REIT, the Company is required, among other things, to distribute at least 90% of its REIT net taxable income to the stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income taxes on income and gains distributed to the stockholders as long as certain requirements are satisfied, principally relating to the nature of income and the level of distributions, as well as other factors. 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 (including any applicable alternative minimum tax for taxable years before 2018) 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. Any gains from the sale of foreclosed properties within two years are subject to U.S. federal and state income taxes at regular corporate rates. As of September 30, 2020, the Company has satisfied all the requirements for a REIT. No provision for federal income taxes has been included in the consolidated financial statements for the three and nine months ended September 30, 2020 and 2019. The Company did not have any uncertain tax positions that met the recognition or measurement criteria of Accounting Standards Codification (“ASC”) 740-10-25, Income Taxes , nor did the Company have any unrecognized tax benefits as of the periods presented herein. The Company recognizes interest and penalties, if any, related to unrecognized tax liabilities as income tax expense in its consolidated statements of operations. For the three and nine months ended September 30, 2020 and 2019, the Company did not incur any interest or penalties. Although the Company files federal and state tax returns, its major tax jurisdiction is federal. The Company’s inception-to-date federal tax returns remain subject to examination by the Internal Revenue Service. Earnings Per Share The Company has a simple equity capital structure with only common stock and preferred stock outstanding. As a result, earnings per share, as presented, represent both basic and dilutive per-share amounts for the periods presented in the consolidated financial statements. Income per basic share of common stock is calculated by dividing net income allocable to common stock by the weighted-average number of shares of common stock issued and outstanding during such period. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. As of September 30, 2020, there has been an ongoing global outbreak of a novel coronavirus (“COVID-19”), which has spread to over 200 countries and territories, including the United States, and has spread to every state in the United States. The World Health Organization has designated COVID-19 as a pandemic, and numerous countries, including the United States, have declared national emergencies with respect to COVID-19. The global impact of the outbreak has been rapidly evolving, and as cases of COVID-19 have continued to be identified in additional countries, many countries have reacted by instituting quarantines and restrictions on travel, closing financial markets and/or restricting trading and operations of non-essential offices and retail centers. Such actions are creating disruption in global supply chains, and adversely impacting many industries. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions. The Company believes the estimates and assumptions underlying its consolidated financial statements are reasonable and supportable based on the information available as of September 30, 2020, however uncertainty over the ultimate impact COVID-19 will have on the global economy generally, and the Company’s business in particular, makes any estimates and assumptions as of September 30, 2020 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results may ultimately differ from those estimates. Segment Information The Company’s primary business is originating, acquiring and structuring real estate-related loans related to high quality commercial real estate. From time to time, the Company may acquire real estate encumbering the senior loans through foreclosure. However, management treats the operations of the real estate acquired through foreclosure as the continuation of the original senior loans. The Company operates in a single segment focused on mezzanine loans, other loans and preferred equity investments, and to a lesser extent, owning and managing real estate. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“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 introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. In April 2019, the FASB issued additional amendments to clarify the scope of ASU 2016-13 and address issues related to accrued interest receivable balances, recoveries, variable interest rates and prepayments, among other things. In May 2019, the FASB issued ASU 2019-05 — Targeted Transition Relief, which provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. In October 2019, the FASB decided that for smaller reporting companies, ASU 2016-13 and related amendments will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company meets the definition of a smaller reporting company under the regulation of the Securities and Exchange Commission. As such, the Company will adopt this ASU and related amendments on January 1, 2023. Management is currently evaluating the impact this change will have on the Company’s consolidated financial statements and disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure framework — Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The objective of ASU 2018-13 is to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of information required by U.S. GAAP. The amendments in ASU 2018-13 added, removed and modified certain fair value measurement disclosure requirements. ASU 2018-13 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 on January 1, 2020. The adoption of ASU 2018-13 did not have a material impact on its consolidated financial statements and disclosures. London Interbank Offered Rate (“LIBOR”) is a benchmark interest rate referenced in a variety of agreements that are used by all types of entities. At the end of 2021, banks will no longer be required to report information that is used to determine LIBOR. As a result, LIBOR could be discontinued. Other interest rates used globally could also be discontinued for similar reasons. 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”). The amendments in ASU 2020-04 provide companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. The provisions of optional relief include: (i) contract modifications - account for the modification as a continuation of the existing contract without additional analysis; (ii) hedging accounting - continue hedge accounting when certain critical terms of a hedging relationship change; and (iii) held-to-maturity (HTM) debt securities - one-time sale and/or transfer to available for sale or trading may be made for HTM debt securities that both reference an eligible reference rate and were classified as HTM before January 1, 2020. Companies can apply the amendments in ASU 2020-04 immediately. However, ASU 2020-04 will only be available for a limited time (generally through December 31, 2022). The Company is currently evaluating the impact of the reference rate reform and ASU 2020-04 on its consolidated financial statements and disclosures.

Business Combinations [Abstract]
Business Combination Disclosure	Note 3. Merger and Issuance of Common Stock to Terra Offshore Funds Merger On February 28, 2020, the Company entered into the Merger Agreement pursuant to which TPT2 was merged with and into the Company, with the Company continuing as the surviving corporation, effective March 1, 2020. In connection with the Merger, each share of common stock, par value $0.01 per share, of TPT2 issued and outstanding immediately prior to the effective time of the Merger was converted into the right to receive from the Company a number of shares of common stock, par value $0.01 per share, of the Company equal to an exchange ratio, which was 1.2031. The exchange ratio was based on the relative net asset values of the Company and TPT2 as of December 31, 2019 as adjusted to reflect changes in the net working capital of each of the Company and TPT2 during the period from January 1, 2020 through March 1, 2020, the effective time for the Merger. For purposes of determining the respective fair values of the Company and TPT2, the value of the loans (or participation interests therein) held by each of the Company and TPT2 was the value of such loans (or participation interests) as set forth in the audited financial statements of the Company as of and for the year ended December 31, 2019. As a result, Terra Fund 7, the sole stockholder of TPT2, received 2,116,785.76 shares of common stock of the Company as consideration in the Merger. The shares of common stock were issued in a private placement in reliance on Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations promulgated thereunder. The following table presents a summary of the consideration exchanged and settlement of the Company’s obligations under participation agreements as a result of the Merger: Total Consideration Equity issued in the Merger $ 34,630,615 $ 34,630,615 Net Assets of TPT2 Received in the Merger Loans held for investment acquired through participation $ 17,688,741 Cash and cash equivalents 16,897,074 Interest receivable 134,543 Other assets 18,384 Accounts payable and accrued expenses (57,433) Due to Manager (50,694) Total identifiable net assets $ 34,630,615 The fair value of the 2,116,785.76 shares of the Company’s stock issued in the Merger as consideration paid for TPT2 was derived from the fair value per share of the Company as of December 31, 2019 as adjusted to reflect the change in the net working capital of the Company during the period from January 1, 2020 through March 1, 2020, the effective time of the Merger. In connection with the Merger, the size of the board of directors of the Company was reduced from eight directors to four directors, with Andrew M. Axelrod, Vikram S. Uppal, Roger H. Beless and Michael L. Evans continuing as directors of the Company. Issuance of Common Stock to Terra Offshore Funds In addition, on March 2, 2020, the Company entered into two separate contribution agreements, one by and among the Company, Terra Offshore Funds and Terra Income Fund International, and another by and among the Company, Terra Offshore Funds and Terra Secured Income Fund 5 International, pursuant to which the Company issued 2,457,684.59 shares of common stock of the Company to Terra Offshore Funds in exchange for the settlement of $32.1 million of participation interests in loans also held by the Company, $8.6 million in cash and other net working capital. The shares of common stock were issued in a private placement in reliance on Section 4(a)(2) under the Securities Act and the rules and regulations promulgated thereunder. The fair value of the 2,457,684.59 shares of the Company’s stock issued in the transaction as consideration paid for Terra Offshore Funds was derived from the fair value per share of the Company as of December 31, 2019, which was the most recently determined fair value per share of the Company. The following table presents a summary of the consideration exchanged and settlement of the Company’s obligations under participation agreements as a result of the Issuance of Common Stock to Terra Offshore Funds: Total Consideration Equity issued to Terra Offshore Funds $ 40,749,378 $ 40,749,378 Net Assets of Terra Offshore Funds Received Investments through participation interest, at fair value $ 32,112,257 Cash and cash equivalents 8,600,000 Interest receivable 270,947 Due to Manager (233,826) Total identifiable net assets $ 40,749,378 On April 29, 2020, the Company repurchased 212,691 shares of common stock that the Company had previously sold to Terra Offshore Funds on September 30, 2019. Terra JV, LLC Prior to the completion of the Merger and the Issuance of Common Stock to Terra Offshore Funds transactions described above, Terra Fund 5 owned approximately 98.6% of the issued and outstanding shares of the Company’s common stock indirectly through its wholly owned subsidiary, Terra JV, of which Terra Fund 5 was the sole managing member, and the remaining issued and outstanding shares of the Company’s common stock were owned by Terra Offshore Funds. As described above, the Company acquired TPT2 in the Merger and, in connection with such transaction, Terra Fund 7 contributed the shares of the Company’s common stock received as consideration in the Merger to Terra JV and became a co-managing member of Terra JV pursuant to the amended and restated operating agreement of Terra JV, dated March 2, 2020 (the “JV Agreement”).

Net Loss on Extinguishment of Obligations Under Participation Agreements As discussed in Note 7 , in the normal course of business, the Company may enter into participation agreements with related parties, primarily other affiliated funds managed by the Manager, and to a lesser extent, unrelated parties. The obligations under participation agreements were released as a result of the Merger and the Issuance of Common Stock to Terra Offshore Funds. In connection with these transactions, the Company recognized a net loss of $0.3 million for the three months ended March 31, 2020, which was primarily related to transaction costs incurred in connection with both transactions.

Loan Risk Rating As described in Note 2 , the Manager evaluates the Company’s loan portfolio on a quarterly basis or more frequently as needed. In conjunction with the quarterly review of the Company’s loan portfolio, the Manager assesses the risk factors of each loan, and assigns a risk rating based on a five-point scale with “1” being the lowest risk and “5” being the greatest risk. The following table allocates the principal balance and the carrying value of the Company’s loans based on the loan risk rating as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 Loan Risk Rating Number of Loans Principal Balance Carrying Value % of Total Number of Loans Principal Balance Carrying Value % of Total 1 0 $ — $ — — % — $ — $ — — % 2 2 24,000,000 24,170,000 5.5 % 5 50,000,000 50,284,751 13.3 % 3 14 322,901,131 324,464,200 73.9 % 17 322,648,317 323,588,017 85.4 % 4 (1) 5 90,449,156 90,703,442 20.6 % — — — — % 5 0 — — — % — — — — % Other (2) 0 — — — % 1 4,740,000 4,740,000 1.3 % 21 $ 437,350,287 439,337,642 100.0 % 23 $ 377,388,317 378,612,768 100.0 % Allowance for loan losses (1,356,737) — Total, net of allowance for loan losses $ 437,980,905 $ 378,612,768 _______________ (1) The increase in number of loans with a loan risk rating of “4” was due to the higher risk in loans collateralized by hospitality and select other asset classes that are particularly negatively impacted by the COVID-19 pandemic. (2) This loan was deemed impaired and removed from the pool of loans on which a general allowance is calculated. As of December 31, 2019, no specific reserve for loan losses was recorded on this loan because the fair value of the collateral was greater than carrying value of the loan. In March 2020, this loan was repaid in full. As of September 30, 2020, the Company had five loans with a loan risk rating of “4” and recorded a general allowance for loan losses of $1.4 million. The following table presents the activity in the Company’s allowance for loan losses for the nine months ended September 30, 2020 and 2019: Nine Months Ended September 30, 2020 2019 Allowance for loan losses, beginning of period $ — $ — Provision for loan losses 1,356,737 — Charge-offs — — Recoveries — — Allowance for loan losses, end of period $ 1,356,737 $ — The allowance for loan losses reserve reflects the macroeconomic impact of the COVID-19 pandemic on commercial real estate markets generally and is not specific to any loan losses or impairments in our portfolio.

Real Estate Disclosure	Note 5. Real Estate Owned, Net Real Estate Activities 2020 — In June 2020, the Company received a notice from a tenant occupying a portion of the office building that the Company acquired in July 2018 via foreclosure of their intention to terminate the lease. In connection with the lease termination effective September 4, 2020, the Company received from the tenant lease termination fee of $0.4 million, which included approximately $0.2 million of cash and $0.2 million of the furniture and fixtures in the office space. The furniture and fixtures have a remaining useful life of 2.5 year life and is being depreciated on a straight-line basis over the remaining useful life. Additionally, the Company wrote off the related unamortized in-place lease intangible assets of $0.9 million, unamortized below-market rent intangible liabilities of $0.6 million and rent receivable of $0.1 million. There was no gain or loss recognized on the lease termination. 2019 — On January 9, 2019, the Company acquired 4.9 acres of adjacent land encumbering a first mortgage via deed in lieu of foreclosure in exchange for the payment of the first mortgage and related fees and expenses. The following table summarizes the carrying value of the first mortgage prior to the deed in lieu of foreclosure on January 9, 2019: Carrying Value of First Mortgage Loan held for investment $ 14,325,000 Interest receivable 439,300 Restricted cash applied against loan principal amount (60,941) $ 14,703,359 The table below summarizes the allocation of the estimated fair value of the real estate acquired on January 9, 2019 based on the policy described in Note 2 : Assets Acquired Real estate owned: Land $ 14,703,359 The Company capitalized transaction costs of approximately $0.2 million to land. For the nine months ended September 30, 2019, the Company recorded an impairment charge of $1.6 million on the land in order to reduce the carrying value of the land to its estimated fair value, which is the estimated selling price less the cost of sale. Real Estate Owned, Net Real estate owned is comprised of 4.9 acres of adjacent land located in Pennsylvania and a multi-tenant office building, with lease intangible assets and liabilities, located in California.

In connection with the foreclosure, the Company assumed four leases whereby the Company is the lessor to the leases. These four tenant leases had remaining lease terms ranging from 6.3 years to 8.8 years as of July 30, 2018 and provide for annual fixed rent increase. Three of the tenant leases each provides two options to renew the lease for five years each and the remaining tenant lease provides one option to renew the lease for five years. In addition, the Company assumed a ground lease whereby the Company is the lessee (or a tenant) to the ground lease. The ground lease had a remaining lease term of 68.3 years and provides for a new base rent every 5 years based on the greater of the annual base rent for the prior lease year or 9% of the fair market value of the land. The next rent reset on the ground lease was scheduled for November 1, 2020, however the Company is currently negotiating with the landlord to determine the fair value of the land, on which the ground rent is based. Since future rent increase on the ground lease is unknown, the Company did not include the future rent increase in calculating the present value of future rent payments. The ground lease does not provide for renewal options. On the date of foreclosure, the Company performed lease classification test on the tenant leases as well as the ground lease in accordance with ASC 840. The result of the lease classification test indicated that the tenant leases and the ground lease shall be classified as operating leases on the date of foreclosure. On January 1, 2019, the Company adopted ASU 2016-02 using a modified retrospective transition approach and chose not to adjust comparable periods ( Note 2 ). The Company elected to use the package of practical expedients for its existing leases whereby the Company did not need to reassess whether a contract is or contains a lease, lease classification and initial direct costs. As a result, the leases continue to be classified as operating leases under ASC 842, Leases . The adoption of ASU 2016-02 did not have any impact on the tenant leases; however, for the ground lease, the Company recognized $16.1 million of both operating lease right-of-use assets and operating lease liabilities on its consolidated balance sheets. No cumulative effect adjustment was recorded because there was no change to operating lease cost. In addition, as of January 1, 2019, the Company had $0.5 million of unamortized leasing commission (initial direct costs) on the tenant leases.

Fair Value Disclosures [Abstract]
Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block]	Note 6. Fair Value Measurements The Company adopted the provisions of ASC 820, Fair Value Measurement (“ASC 820”), which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 established a fair value hierarchy that prioritizes and ranks the level of market price observability used in measuring investments at fair value. Market price observability is impacted by a number of factors, including the type of investment, the characteristics specific to the investment, and the state of the marketplace (including the existence and transparency of transactions between market participants). Investments with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in an orderly market will generally have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Investments measured and reported at fair value are classified and disclosed into one of the following categories based on the inputs as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets and liabilities that the Company has the ability to access. Level 2 — Pricing inputs are other than quoted prices in active markets, including, but not limited to, quoted prices for similar assets and liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs. Level 3 — Significant unobservable inputs are based on the best information available in the circumstances, to the extent observable inputs are not available, including the Company’s own assumptions used in determining the fair value of investments. Fair value for these investments are determined using valuation methodologies that consider a range of factors, including but not limited to the price at which the investment was acquired, the nature of the investment, local market conditions, trading values on public exchanges for comparable securities, current and projected operating performance, and financing transactions subsequent to the acquisition of the investment. The inputs into the determination of fair value require significant management judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. As of September 30, 2020 and December 31, 2019, the Company has not elected the fair value option for its financial instruments, including loans held for investment, loans held for investment acquired through participation, obligations under participation agreements, term loan payable, mortgage loan payable, repurchase agreement payable and revolving credit facility payable. Such financial instruments are carried at cost, less impairment or less net deferred costs , where applicable. Marketable securities are financial instruments that are reported at fair value. Financial Instruments Carried at Fair Value on a Recurring Basis From time to time, the Company may invest in short-term debt and equity securities which are classified as available-for-sale securities, which are presented at fair value on the consolidated balance sheet. Changes in the fair value of equity securities are recognized in earnings. Changes in the fair value of debt securities are reported in other comprehensive income until the securities are realized. The following tables present fair value measurements of marketable securities, by major class, as of September 30, 2020, according to the fair value hierarchy: September 30, 2020 Fair Value Measurements Level 1 Level 2 Level 3 Total Marketable Securities: Equity securities $ 1,205,001 $ — $ — $ 1,205,001 Debt securities — — — — Total $ 1,205,001 $ — $ — $ 1,205,001 The following table presents the activities of the marketable securities for the periods presented.

Valuation Process for Fair Value Measurement The fair value of the Company’s investment in equity securities is determined based on quoted prices in an active market and is classified as Level 1 of the fair value hierarchy. Market quotations are not readily available for the Company’s real estate-related loan investments, all of which are included in Level 3 of the fair value hierarchy, and therefore these investments are valued utilizing a yield approach, i.e. a discounted cash flow methodology to arrive at an estimate of the fair value of each respective investment in the portfolio using an estimated market yield. In following this methodology, investments are evaluated individually, and management takes into account, in determining the risk-adjusted discount rate for each of the Company’s investments, relevant factors, including available current market data on applicable yields of comparable debt/preferred equity instruments; market credit spreads and yield curves; the investment’s yield; covenants of the investment, including prepayment provisions; the portfolio company’s ability to make payments, net operating income and debt-service coverage ratio; construction progress reports and construction budget analysis; the nature, quality and realizable value of any collateral (and loan-to-value ratio); the forces that influence the local markets in which the asset (the collateral) is purchased and sold, such as capitalization rates, occupancy rates, rental rates and replacement costs; and the anticipated duration of each real estate-related loan investment. The Manager designates a valuation committee to oversee the entire valuation process of the Company’s Level 3 loans. The valuation committee is comprised of members of the Manager’s senior management, deal and portfolio management teams, who meet on a quarterly basis, or more frequently as needed, to review the Company investments being valued as well as the inputs used in the proprietary valuation model. Valuations determined by the valuation committee are supported by pertinent data and, in addition to a proprietary valuation model, are based on market data, industry accepted third-party valuation models and discount rates or other methods the valuation committee deems to be appropriate. Because there is no readily available market for these investments, the fair values of these investments are approved in good faith by the Manager pursuant to the Company’s valuation policy. The fair values of the Company’s mortgage loan payable, repurchase agreement payable, term loan payable and revolving credit facility payable are determined by discounting the contractual cash flows at the interest rate the Company estimates such arrangements would bear if executed in the current market. The following table summarizes the valuation techniques and significant unobservable inputs used by the Company to value the Level 3 loans as of September 30, 2020 and December 31, 2019. The tables are not intended to be all-inclusive, but instead identify the significant unobservable inputs relevant to the determination of fair values.

Origination and Extension Fee Expense Pursuant to the Management Agreement, the Manager or its affiliates receives an origination fee in the amount of 1% of the amount used to originate, fund, acquire or structure real estate-related loans, including any third-party expenses related to such loans. In the event that the term of any real estate-related loan held by the Company is extended, the Manager also receives an extension fee equal to the lesser of (i) 1% of the principal amount of the loan being extended or (ii) the amount of fee paid to the Company by the borrower in connection with such extension. Asset Management Fee Under the terms of the Management Agreement, the Manager or its affiliates provides the Company with certain investment management services in return for a management fee.

Merger and Issuance of Common Stock to Terra Offshore Funds As discussed in Note 3 , on March 1, 2020, TPT2 merged with and into the Company with the Company continuing as the surviving company. In connection with the Merger, the Company issued 2,116,785.76 shares of common stock of the Company to Terra Fund 7, the sole stockholder of TPT2, as consideration in the Merger. In addition, on March 2, 2020, Terra Offshore Funds contributed cash and released obligations under the participation agreements to the Company ( Note 3 ) in exchange for the issuance of 2,457,684.59 shares of common stock of the Company. As described in Note 3 , Terra Fund 7 contributed the shares of the Company’s common stock received as consideration in the Merger to Terra JV and became a co-managing member of Terra JV pursuant to the JV Agreement. The JV Agreement and related stockholders agreement between Terra JV and the Company, dated March 2, 2020, provide for the joint approval of Terra Fund 5 and Terra Fund 7 with respect to certain major decisions that are taken by Terra JV and the Company. As of September 30, 2020, Terra JV owns 87.4% of the issued and outstanding shares of the Company’s common stock with the remainder held by Terra Offshore Funds, and Terra Fund 5 and Terra Fund 7 own an 87.6% and 12.4% interest, respectively, in Terra JV. Terra Real Estate Credit Opportunities Fund, L.P. On August 3, 2020, the Company entered into a subscription agreement with Terra Real Estate Credit Opportunities Fund, L.P. (“Terra Opportunities Fund”) whereby the Company committed to fund up to $50.0 million to purchase limited partnership interests in Terra Opportunities Fund. Terra Opportunities F und’s primary investment objective is to generate attractive risk-adjusted returns by purchasing secondary performing and non-performing mortgages, loans, mezzanines and other credit instruments supported by underlying commercial real estate assets. Terra Opportunities Fund may also opportunistically originate high-yield mortgages or loans in real estate special situations including rescue financings, bridge loans, restructurings and bankruptcies (including debtor-in-possession loans). The general partner of Terra Opportunities Fund is Terra Real Estate Credit Opportunities Fund GP, LLC , which is a subsidiary of the Company’s sponsor, Terra Capital Partners, LLC . As of September 30, 2020, none of the commitment has been drawn. On November 5, 2020, the Company funded $3.6 million of the commitment. Terra International Fund 3, L.P. On September 30, 2019, the Company entered into a Contribution and Repurchase Agreement with Terra International Fund 3, L.P. (“Terra International 3”) and Terra Offshore Funds, a wholly-owned subsidiary of Terra International 3. Pursuant to this agreement, Terra International 3, through Terra Offshore Funds, contributed cash in the amount of $3.6 million to the Company in exchange for 212,691 shares of common stock, at a price of $17.02 per share. In addition, Terra International 3 agreed to contribute to the Company future cash proceeds, if any, raised from time to time by it, and the Company agreed to issue shares of common stock to International Fund 3 in exchange for any such future cash proceeds, in each case pursuant to and in accordance with the terms and conditions specified in the agreement. The shares were issued in a private placement in reliance on Section 4(a)(2) of the Securities Act and the rules and regulations promulgated thereunder. Under Cayman securities law, when there is a change in the terms of the offering, previously admitted partners have rights to rescind their subscription. On September 24, 2019, Terra International 3 amended its private placement memorandum to change its term from finite life to perpetual life with limited opportunity for liquidity, as well as to change the selling commission structure and to provide for a dividend reinvestment plan. As a result of the change in the terms of the offering, Terra International 3 received requests to rescind all of the units of its limited partnership interest at a price of $100,000 per unit. On April 29, 2020, the Company repurchased, at a price of $17.02 per share, the 212,691 shares of common stock that the Company had previously sold to Terra Offshore Funds on September 30, 2019. Terra International 3 honored all of the rescission requests that it had received with proceeds from the repurchase. Participation Agreements In the normal course of business, the Company may enter into participation agreements (“PAs”) with related parties, primarily other affiliated funds managed by the Manager, and to a lesser extent, unrelated parties (the “Participants”). The purpose of the PAs is to allow the Company and an affiliate to originate a specified loan when, individually, the Company does not have the liquidity to do so or to achieve a certain level of portfolio diversification. The Company may transfer portions of its investments to other Participants or it may be a Participant to a loan held by another entity. ASC 860, Transfers and Servicing (“ASC 860”) , establishes accounting and reporting standards for transfers of financial assets. ASC 860-10 provides consistent standards for distinguishing transfers of financial assets that are sales from transfers that are secured borrowings. The Company has determined that the participation agreements it enters into are accounted for as secured borrowings under ASC 860 (See “ Participation interests ” in Note 2 and “ Obligations under Participation Agreements ” in ( Note 7 ). Participation Interests Purchased by the Company The below table lists the loan interests participated in by the Company via PAs as of September 30, 2020 and December 31, 2019. In accordance with the terms of each PA, each Participant’s rights and obligations, as well as the proceeds received from the related borrower/issuer of the loan, are based upon their respective pro rata participation interest in the loan.

In connection with the Merger and the Issuance of Common Stock to Terra Offshore Funds, the related participation obligations were settled. These investments are held in the name of the Company, but each of the Participant’s rights and obligations, including interest income and other income ( e.g. , exit fee, prepayment income) and related fees/expenses ( e.g. , disposition fees, asset management and asset servicing fees), are based upon their respective pro rata participation interest in such participated investments, as specified in the respective PA. The Participants’ share of the investments is repayable only from the proceeds received from the related borrower/issuer of the investments and, therefore, the Participants also are subject to credit risk ( i.e. , risk of default by the underlying borrower/issuer). Pursuant to the PAs with these entities, the Company receives and allocates the interest income and other related investment income to the Participants based on their respective pro rata participation interest. The Participants pay any expenses, including any fees to the Manager, only on their respective pro rata participation interest, subject to the terms of the respective governing fee arrangements.

Debt Disclosure [Abstract]
Debt Disclosure	Note 8. Debt Term Loan On September 3, 2020, Terra Mortgage Capital I, LLC (the “Issuer” or the “Seller” ), a special-purpose indirect wholly-owned subsidiary of the Company, entered into an Indenture and Credit Agreement (the “Indenture and Credit Agreement”) with Goldman Sachs Bank USA, as initial lender (“Goldman”) and Wells Fargo Bank, National Association, as the trustee, custodian, collateral agent, loan agent and note administrator (“Wells Fargo”). The Indenture and Credit Agreement provides for (A) the borrowing by the Issuer from Goldman of approximately $103.0 million under a floating rate loan (the “Term Loan”) and (B) the issuance by the Issuer to Terra Mortgage Portfolio I, LLC (the “Class B Holder”) of an aggregate of approximately $76.7 million principal amount of Class B Income Notes due 2025 (the “Class B Notes” and, together with the Term Loan, the “Debt”). The Class B Holder is the parent of the Issuer and a wholly-owned subsidiary of the Company, and the sole holder of the Class B Notes. The Class B Holder is consolidated by the Company and the Term Loan represents amount due to Goldman under the Indenture and Credit Agreement. In addition, pursuant to the terms and conditions of the Indenture and Credit Agreement, Goldman has agreed to provide $3.6 million of additional future advances (the “Committed Advances”), and may provide up to $11.6 million of additional future discretionary advances, in connection with certain outstanding funding commitments under mortgage assets owned by the Issuer and financed under the Indenture and Credit Agreement (the “Mortgage Assets”). The stated maturity date of the Debt is March 14, 2025. The Term Loan bears interest at a variable rate initially equal to LIBOR (the “Benchmark Rate”) (but not less than 1.0% per annum), plus a margin of 4.25% per annum (plus 0.50% on and after the payment date in October 2022, plus 0.25% on and after the payment date in October 2023), payable each month, on the day specified in the Indenture and Credit Agreement beginning in September 2020 (each a “Payment Date”). The Benchmark Rate will convert to an alternate index rate following the occurrence of certain transition events (the “Alternate Benchmark Rate”). Except as described below, and provided there is no default under the Indenture and Credit Agreement, the Class B Notes are entitled to residual amounts collected by the Issuer in respect of Mortgage Assets, after payment of debt service on the Term Loan. The Indenture and Credit Agreement is a term loan and does not contain any mark-to-market or margin provisions. Within a specified period following a monetary or material non-monetary default under a Mortgage Asset, the Class B Holder is required to prepay the portion of the Term Loan that is allocable to such Mortgage Asset (such prepayment is without premium, yield maintenance or other penalty). In connection with entering into the Indenture and Credit Agreement, the Company incurred $2.4 million of deferred financing costs, including a $1.3 million upfront fee paid to Goldman, which are being amortized to interest expense over the term of the facility. The Issuer also pays, with respect to the Committed Advances, an annual fee, payable monthly, equal to the Benchmark Rate or Alternate Benchmark Rate, as applicable, subject to a floor of 1.0% per annum, plus 4.25%. In connection with the Indenture and Credit Agreement, the Company entered into a non-recourse carveout Guaranty (the "Guaranty") in favor of Goldman, pursuant to which the Company guarantees the payment of certain losses, damages, costs, expenses, and other obligations incurred by Goldman in connection with the occurrence of fraud, intentional misrepresentation, or willful misconduct by the Issuer, Class B Holder or the Company, and certain other occurrences including breaches of certain provisions under the Indenture and Credit Agreement. The Company also guarantees the payment of the aggregate outstanding amount of the Term Loan upon the occurrence of certain bankruptcy events. Under the Guaranty, the Company is required to maintain (a) a minimum tangible net worth in an amount not less than seventy-five percent (75%) of its tangible net worth as of September 3, 2020, (b) a minimum liquidity of $10 million, and (c) an EBITDA to interest expense ratio of not less than 1.5 to 1.0. Failure to satisfy such maintenance covenants would constitute an event of default under the Indenture and Credit Agreement. As of September 30, 2020, the Company is in compliance with these covenants. The Term Loan is secured by first-priority security interests in substantially all of the assets of the Issuer, including all of the Mortgage Assets (other than excluded property and subject to certain permitted liens), including specified cash accounts that include the accounts into which Mortgage Asset proceeds are or will be paid. The Mortgage Assets are serviced and administered by an independent third-party servicer. The principal and interest on the Term Loan are repaid before repayment of the principal on the Class B Notes on each payment date of each month in accordance with the priority of payments as set forth in the Indenture and Credit Agreement, beginning in September 2020. Such payments are subject to certain fees for taxes, filings and administrative expenses. Upon the occurrence of a Term Loan Principal Trigger Event (as defined below), 100% of the payment of the principal proceeds are applied to the Term Loan principal after payment of certain fees and other amounts as described in the Indenture and Credit Agreement. A “Term Loan Principal Trigger Event” means as of any date of determination, an event that will be deemed to have occurred on the first date on which the aggregate principal balance of the Mortgage Assets is less than or equal to the product of (x) 75% multiplied by (y) the aggregate principal balance of the Mortgage Assets as of the closing date, plus any future advances made on such Mortgage Assets prior to such date of determination. As of September 30, 2020, there was no Term Loan Principal Trigger Event. The Class B Notes and the Term Loan are redeemable by the Issuer upon the occurrence of certain tax events in accordance with the terms and provisions of the Indenture and Credit Agreement. The following tables present detailed information with respect to each borrowing under the Term Loan as of September 30, 2020: September 30, 2020 Mortgage Assets Borrowings Under the Term Loan (1)(2) Principal Amount Carrying Value Fair 330 Tryon DE LLC $ 22,800,000 $ 22,898,718 $ 22,810,937 13,680,000 1389 Peachtree St, LP; 1401 Peachtree St, LP; and 48,973,981 49,206,919 49,138,842 29,293,059 AGRE DCP Palm Springs, LLC 44,136,105 44,346,025 44,334,772 24,180,687 MSC Fields Peachtree Retreat, LLC 23,308,334 23,439,777 23,398,194 13,985,001 Patrick Henry Recovery Acquisition, LLC 18,000,000 18,039,014 17,922,482 10,800,000 University Park Berkeley, LLC 23,741,994 23,773,961 23,798,728 13,950,000 $ 180,960,414 $ 181,704,414 $ 181,403,955 $ 105,888,747 _______________ (1) Borrowings under the Term Loan bear interest at LIBOR plus 4.25% with a LIBOR floor of 1.00%, or 5.25% as of September 30, 2020 using LIBOR of 0.15%. (2) The maturity of the Term Loan is March 14, 2025, however the maturity of each borrowing under the Term Loan matches the maturity of the respective Mortgage Asset. Repurchase Agreement On December 12, 2018, Terra Mortgage Capital I, LLC entered into an Uncommitted Master Repurchase Agreement (the “Master Repurchase Agreement”) with Goldman Sachs Bank USA. The Master Repurchase Agreement provided for advances of up to $150.0 million in the aggregate, which the Company used to finance certain secured performing commercial real estate loans. Advances under the Master Repurchase Agreement accrued interest at a per annum pricing rate equal to the sum of (i) the 30-day LIBOR and (ii) the applicable spread, and had a maturity date of December 12, 2020. The actual terms of financing for each asset was determined at the time of financing in accordance with the Master Repurchase Agreement. The Master Repurchase Agreement contained margin call provisions that provide Goldman with certain rights in the event of a decline in the market value of the assets purchased under the Master Repurchase Agreement. Upon the occurrence of a margin deficit event, Goldman required the Seller to make a payment to reduce the outstanding obligation to eliminate any margin deficit. For the period from January 1, 2020 to the date of the termination of the Master Repurchase Agreement on September 3, 2020, the Company received a margin call on one of the borrowings and as a result, made a repayment of $3.4 million to reduce the outstanding obligation under the Master Repurchase Agreement. In connection with the Master Repurchase Agreement, the Company entered into a Guarantee Agreement in favor of Goldman (the “Guarantee Agreement”), pursuant to which the Company would guarantee the obligations of the Seller under the Master Repurchase Agreement. Subject to certain exceptions, the maximum liability under the Master Repurchase Agreement would not exceed 50% of the then currently outstanding repurchase obligations under the Master Repurchase Agreement. On September 3, 2020, the Company terminated the Master Repurchase Agreement and replaced it with the Term Loan as described above. In connection with the termination of the Master Repurchase Agreement, the Issuer repurchased all of its assets sold to Goldman pursuant to the Master Repurchase Agreement with the proceeds from the Term Loan, and Goldman released all security interests in such assets. In addition, Goldman unconditionally released the Company from, and terminated, the Guarantee Agreement in favor of Goldman, dated as of December 12, 2018, which provided for the guarantee by the Company of the obligations of the Issuer under the Master Repurchase Agreement, subject to certain exceptions and limitations. The Master Repurchase Agreement and the Guarantee Agreement contained various representations, warranties, covenants, conditions precedent to funding, events of default and indemnities that are customary for agreements of these types. In addition, the Guarantee Agreement contained financial covenants, which required the Company to maintain: (i) liquidity of at least 10% of the then-current outstanding amount under the Master Repurchase Agreement; (ii) cash liquidity of at least the greater of $5 million or 5% of the then-current outstanding amount under the Master Repurchase Agreement; (iii) tangible net worth at an amount equal to or greater than 75% of the Company’s tangible net worth as of December 12, 2018, plus 75% of new capital contributions thereafter; (iv) an EBITDA to interest expense ratio of not less than 1.50 to 1.00; and (v) a total indebtedness to tangible net worth ratio of not more than 3.00 to 1.00. As of December 31, 2019, the Company was in compliance with these covenants. In connection with entering into the Master Repurchase Agreement, the Company incurred $2.8 million of deferred financing costs, which were being amortized to interest expense over the term of the facility. In connection with the termination of the Master Repurchase Agreement, the remaining $0.5 million of unamortized deferred financing costs were carried over to the Term Loan to be amortized over the term of the Term Loan. As of December 31, 2019, unamortized deferred financing costs were $1.5 million.

Revolving Credit Facility On June 20, 2019, Terra LOC Portfolio I, LLC, a special-purpose indirect wholly-owned subsidiary of the Company, entered into a credit agreement with Israel Discount Bank of New York to provide for revolving credit loans of up to $35.0 million in the aggregate (“Revolving Credit Facility”), which the Company expects to use for short term financing needed to bridge the timing of anticipated loans repayments and funding obligations. Borrowings under the Revolving Credit Facility can be either prime rate loans or LIBOR rate loans and accrue interest at an annual rate of prime rate plus 1% or LIBOR plus 4% with a floor of 6%. Each loan made under the Revolving Credit Facility shall be in a minimum aggregate principal amount of the lesser of $1.0 million or the then unused amount under the facility and cannot be more than $25.0 million in the aggregate with respect to each asset purchased with the proceeds from the Revolving Credit Facility. The Revolving Credit Facility was scheduled to mature on June 20, 2020. The Revolving Credit Facility was amended to extend the maturity to September 3, 2020. The Company is currently negotiating with the lender to extend the maturity of the Revolving Credit Facility by a year and the lender has waived the maturity default. In connection with obtaining the Revolving Credit Facility, the Company incurred deferred financing costs of $0.3 million, which was amortized over the original term of the facility. As of September 30, 2020, the amount outstanding under the Revolving Credit Facility was $25.0 million. The Revolving Credit Facility requires the Company to maintain: (i) an EBITDA to interest expense ratio of not less than 1.00; (ii) cash liquidity of at least $7.0 million; (iii) tangible net worth of at least $200.0 million; and (iii) a total indebtedness to tangible net worth ratio of not more than 1.75 to 1.00. Additionally, the Revolving Credit Facility requires Terra LOC Portfolio I, LLC to maintain a tangible net worth of at least $100.0 million. As of September 30, 2020 and December 31, 2019, both the Company and Terra LOC Portfolio I, LLC are in compliance with these covenants. For the nine months ended September 30, 2020 and 2019, the Company borrowed $35.0 million and $4.0 million under the Revolving Credit Facility, respectively, and made repayments of $10.0 million and $4.0 million, respectively. Mortgage Loan Payable As of September 30, 2020, the Company had a $44.2 million mortgage loan payable collateralized by a multi-tenant office building that the Company acquired through foreclosure. The following table presents certain information about the mortgage loan payable as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 Lender Current Maturity Date (1) Principal Amount Carrying Value Carrying Value of Carrying Value Carrying Value of Centennial Bank LIBOR + 3.85% September 27, 2022 $ 44,210,228 $ 44,327,598 $ 50,348,316 $ 44,753,633 $ 52,776,236 _______________ (1) In September 2020, the Company exercised the option to extend the maturity of the mortgage loan payable by two years.

As discussed in Note 2 , the Company follows the guidance in ASC 860 when accounting for loan participations. Such guidance requires participation interests meet certain criteria in order for the interest transaction to be recorded as a sale. Loan participations from the Company which do not qualify for sale treatment remain on the Company’s consolidated balance sheets and the proceeds are recorded as obligations under participation agreements. As of September 30, 2020 and December 31, 2019, obligations under participation agreements had a carrying value of approximately $89.2 million and $103.2 million, respectively, and the carrying value of the loans that are associated with these obligations under participation agreements was approximately $223.5 million and $203.0 million, respectively, (see “ Participation Agreements ” in Note 7

Commitments and Contingencies Disclosure	Note 9. Commitments and Contingencies Impact of COVID-19 As further discussed in Note 2 , the full extent of the impact of COVID-19 on the global economy generally, and the Company’s business in particular, is uncertain. As of September 30, 2020, no contingencies have been recorded on the Company’s consolidated balance sheet as a result of COVID-19, however as the global pandemic continues and the economic implications worsen, it may have long-term impacts on the Company’s financial condition, results of operations, and cash flows. Refer to Note 2 for further discussion of COVID-19. Unfunded Commitments on Loans Held for Investment Certain of the Company’s loans contain provisions for future fundings, which are subject to the borrower meeting certain performance-related metrics that are monitored by the Company. These fundings amounted to approximately $64.2 million and $116.7 million as of September 30, 2020 and December 31, 2019, respectively. The Company expects to maintain sufficient cash on hand to fund such unfunded commitments, primarily through matching these commitments with principal repayments on outstanding loans and proceeds from the Revolving Credit Facility. Unfunded Investment Commitment As discussed in N ote 7 , On August 3, 2020, the Company entered into a subscription agreement with Terra Opportunities Fund whereby the Company committed to fund up to $50.0 million to purchase limited partnership interests in Terra Opportunities Fund. As of September 30, 2020, none of the commitment has been funded. Other The Company enters into contracts that contain a variety of indemnification provisions. The Company’s maximum exposure under these arrangements is unknown; however, the Company has not had prior claims or losses pursuant to these contracts. The Manager has reviewed the Company’s existing contracts and expects the risk of loss to the Company to be remote. The Company is not currently subject to any material legal proceedings and, to the Company’s knowledge, no material legal proceedings are threatened against the Company. From time to time, the Company may be a party to certain legal proceedings in the ordinary course of business, including proceedings relating to the enforcement of the Company’s rights under contracts with its portfolio companies. While the outcome of any legal proceedings cannot be predicted with certainty, the Company does not expect that any such proceedings will have a material adverse effect upon its financial condition or results of operations. See Note 7 for a discussion of the Company’s commitments to the Manager.

The Company, at its option, may redeem the shares, with written notice, at a redemption price of $1,000 per share, plus any accrued unpaid distribution through the date of the redemption. The Series A Preferred Stock carries a redemption premium of $50 per share if redeemed prior to January 1, 2019. The Series A Preferred Stock generally has no voting rights. However, the Series A Preferred Stock holders’ voting is required if (i) authorization or issuance of any securities senior to the Series A Preferred Stock; (ii) an amendment to the Company’s charter that has a material adverse effect on the rights and preference of the Series A Preferred Stock; and (iii) any reclassification of the Series A Preferred Stock. Common Stock As discussed in Note 3 , on March 1, 2020, TPT2 merged with and into the Company with the Company continuing as the surviving corporation. In connection with the Merger, the Company issued 2,116,785.76 shares of common stock of the Company to Terra Fund 7, the sole stockholder of TPT2, as consideration in the Merger. In addition, on March 2, 2020, the Company issued 2,457,684.59 shares of common stock of the Company in exchange for the settlement of certain participation interests in loans held by the Company and cash. As described in Note 3 , Terra Fund 7 contributed the shares of the Company’s common stock received as consideration in the Merger to Terra JV and became a co-managing member of Terra JV pursuant to the JV Agreement. The JV Agreement and related stockholders agreement between Terra JV and the Company, dated March 2, 2020, provide for the joint approval of Terra Fund 5 and Terra Fund 7 with respect to certain major decisions that are taken by Terra JV and the Company. As of September 30, 2020, Terra JV owns 87.4% of the issued and outstanding shares of the Company’s common stock with the remainder held by Terra Offshore Funds, and Terra Fund 5 and Terra Fund 7 own an 87.6% and 12.4% interest, respectively, in Terra JV. On September 30, 2019, the Company issued 212,691 shares of its common stock to Terra Offshore Funds at a price of $17.02 per share for total proceeds of $3.6 million. On April 29, 2020, the Company repurchased, at a price of $17.02 per share, the 212,691 shares it previously sold to Terra Offshore Funds ( Note 7 ). Distributions The Company generally intends to distribute substantially all of its taxable income, which does not necessarily equal net income as calculated in accordance with U.S. GAAP, to its stockholders each year to comply with the REIT provisions of the Internal Revenue Code. All distributions will be made at the discretion of the Company’s board of directors and will depend upon its taxable income, financial condition, maintenance of REIT status, applicable law, and other factors as its board of directors deems relevant.

Accounting Policies [Abstract]
Consolidation	Basis of Presentation and Principles of Consolidation    The interim consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and include all of the Company’s accounts and those of its consolidated subsidiaries. The accompanying interim financial statements of the Company and related financial information have been prepared pursuant to the requirements for reporting on Form 10-Q and Articles 6 or 10 of Regulation S-X. All intercompany balances and transactions have been eliminated.
Finance Receivable Policy	Loans Held for Investment The Company originates, acquires, and structures real estate-related loans generally to be held to maturity. Loans held for investment are carried at the principal amount outstanding, adjusted for the accretion of discounts on investments and exit fees, and the amortization of premiums on investments and origination fees. The Company’s preferred equity investments, which are economically similar to mezzanine loans and subordinate to any loans but senior to common equity, are accounted for as loans held for investment. Loans are carried at cost less allowance for loan losses.
Allowance for Loan Losses Policy	Allowance for Loan Losses The Company’s loans are typically collateralized by either the sponsors’ equity interest in the real estate properties or the underlying real estate properties. As a result, the Company regularly evaluates the extent and impact of any credit migration associated with the performance and/or value of the underlying collateral property as well as the financial and operating capability of the borrower/sponsor on a loan-by-loan basis. Specifically, a property’s operating results and any cash reserves are analyzed and used to assess (i) whether cash from operations and/or reserve balances are sufficient to cover the debt service requirements currently and into the future; (ii) the ability of the borrower to refinance the loan; and/or (iii) the property’s liquidation value. The Company also evaluates the financial wherewithal of the sponsor as well as its competency in managing and operating the real estate property. 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 and finance personnel, who utilize various data sources, including (i) periodic financial data such as debt service coverage ratio, property occupancy, tenant profile, rental rates, operating expenses, the borrower’s exit plan, the capitalization and discount rates; (ii) site inspections; and (iii) current credit spreads and discussions with market participants. The Manager performs a quarterly evaluation for possible impairment of the Company’s portfolio of loans. A loan is impaired if it is deemed probable that the Company will not be able to collect all amounts due according to the contractual terms of the loan. Impairment is measured based on the present value of expected future cash flows or the fair value of the collateral, if the loan is collateral dependent. Upon measurement of impairment, the Company records an allowance to reduce the carrying value of the loan with a corresponding charge to net income. In conjunction with the quarterly evaluation of loans not considered impaired, the Manager assesses the risk factors of each loan and assigns each loan a risk rating between 1 and 5, which is an average of the numerical ratings in the following categories: (i) sponsor capability and financial condition; (ii) loan and collateral performance relative to underwriting; (iii) quality and stability of collateral cash flows and/or reserve balances; and (iv) loan to value. Based on a 5-point scale, the Company’s loans are rated “1” through “5”, from less risk to greater risk, as follows: Risk Rating Description 1 Very low risk 2 Low risk 3 Moderate/average risk 4 Higher risk 5 Highest risk The Company records an allowance for loan losses equal to (i) 1.5% of the aggregate carrying amount of loans rated as a “4”, plus (ii) 5% of the aggregate carrying amount of loans rated as a “5”, plus (iii) impaired loan reserves, if any. There may be circumstances where the Company modifies a loan by granting the borrower a concession that it might not otherwise consider when a borrower is experiencing financial difficulty or is expected to experience financial difficulty in the foreseeable future. Such concessionary modifications are classified as troubled debt restructurings (“TDR”s) unless the modification solely results in a delay in a payment that is insignificant. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes.
Marketable Securities Policy	Marketable Securities    The Company from time to time invests in short term debt and equity securities. These securities are classified as available-for-sale and are carried at fair value. Changes in the fair value of equity securities are recognized in earnings. Changes in the fair value of debt securities are reported in other comprehensive income until a gain or loss on the securities is realized.
Real Estate Owned	Real Estate Owned, Net Real estate acquired is recorded at its estimated fair value at acquisition and is shown net of accumulated depreciation and impairment charges. Acquisition of properties generally are accounted for as asset acquisitions. Under asset acquisition accounting, the costs to acquire real estate, including transaction costs, are accumulated and then allocated to individual assets and liabilities acquired based upon their relative fair value. The Company allocates the purchase price of its real estate acquisitions to land, building, tenant improvements, acquired in-place leases, intangibles for the value of any above or below market leases at fair value and to any other identified intangible assets or liabilities. The Company amortizes the value allocated to in-place leases over the remaining lease term, which is reported in depreciation and amortization expense on its consolidated statements of operations. The value allocated to above or below market leases are amortized over the remaining lease term as an adjustment to rental income. Real estate assets are depreciated using the straight-line method over their estimated useful lives: buildings and improvements - not to exceed 40 years, and tenant improvements - shorter of the lease term or life of the asset. Ordinary repairs and maintenance which are not reimbursed by the tenants are expensed as incurred. Major replacements and betterments which improve or extend the life of the asset are capitalized and depreciated over their estimated useful life.
Lessee, Leases Policy	Leases The Company determines if an arrangement is a lease at inception. Operating leases in which the Company is the lessee are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s lease typically does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made in advance and excludes lease incentives if there were any. The Company’s lease term may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Revenue Recognition	Revenue Recognition Revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Interest Income: Interest income is accrued based upon the outstanding principal amount and contractual terms of the loans and preferred equity investments that the Company expects to collect and it is accrued and recorded on a daily basis. Discounts and premiums on investments purchased are accreted or amortized over the expected life of the respective loan using the effective yield method, and are included in interest income in the consolidated statements of operations. Loan origination fees and exit fees, net of portions attributable to obligations under participation agreements, are capitalized and amortized or accreted to interest income over the life of the investment using the effective yield method. Income accrual is generally suspended for loans at the earlier of the date at which payments become 90 days past due or when, in the opinion of the Manager, recovery of income and principal becomes doubtful. Outstanding interest receivable is assessed for recoverability. Interest is then recorded on the basis of cash received until accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. The Company holds loans in its portfolio that contain paid-in-kind (“PIK”) interest provisions. The PIK interest, which represents contractually deferred interest that is added to the principal balance that is due at maturity, is recorded on the accrual basis. Real Estate Operating Revenues: Real estate operating revenue is derived from leasing of space to various types of tenants. The leases are for fixed terms of varying length and generally provide for annual rent increases and expense reimbursements to be paid in monthly installments. Lease revenue, or rental income from leases, is recognized on a straight-line basis over the term of the respective leases. Additionally, the Company recorded above- and below-market lease intangibles, which are included in real estate owned, net, in connection with the acquisition of the real estate properties. These intangible assets and liabilities are amortized to lease revenue over the remaining contractual lease term. Other Revenues: Prepayment fee income is recognized as prepayments occur. All other income is recognized when earned.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents	Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments, with original maturities of ninety days or less when purchased, as cash equivalents. Cash and cash equivalents are exposed to concentrations of credit risk. The Company maintains all of its cash at financial institutions which, at times, may exceed the amount insured by the Federal Deposit Insurance Corporation. Restricted cash represents cash held as additional collateral by the Company on behalf of the borrowers related to the investments in loans or preferred equity instruments for the purpose of such borrowers making interest and property-related operating payments. Restricted cash is not available for general corporate purposes. The related liability is recorded in “ Interest reserve and other deposits held on investments ” on the consolidated balance sheets. Cash held in escrow by lender represents amounts funded to an escrow account for debt services and tenant improvements. The following table provides a reconciliation of cash, cash equivalents and restricted cash in the Company’s consolidated balance sheets to the total amount shown in its consolidated statements of cash flows: September 30, 2020 September 30, 2019 Cash and cash equivalents $ 65,729,695 $ 36,360,811 Restricted cash 26,017,300 22,530,675 Cash held in escrow by lender 1,864,351 1,794,653 Total cash, cash equivalents and restricted cash shown in the consolidated $ 93,611,346 $ 60,686,139
Participation Interests	Participation Interests Loan participations from the Company which do not qualify for sale treatment remain on the Company’s consolidated balance sheets and the proceeds are recorded as obligations under participation agreements. For the investments for which participation has been granted, the interest earned on the entire loan balance is recorded within “ Interest income ” and the interest related to the participation interest is recorded within “ Interest expense from obligations under participation agreements ” in the consolidated statements of operations. Interest expense from obligations under participation agreement is reversed when recovery of interest income on the related loan becomes doubtful. See “ Obligations under Participation Agreements ” in Note 8 for additional information.
Term Loan	Term Loan     The Company finances certain of its senior loans through borrowings under an indenture and credit agreement. The Company accounts for the borrowings as a term loan, which is carried at the contractual amount (cost), net of unamortized deferred financing fees.
Repurchase Agreements	Repurchase Agreement The Company financed certain of its senior loans through repurchase transactions under a master repurchase agreement. The Company accounted for the repurchase transactions as secured borrowing transactions, which are carried at their contractual amounts (cost), net of unamortized deferred financing fees.
Fair Value Measurement Policy	Fair Value Measurements U.S. GAAP establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The Company has not elected the fair value option for its financial instruments, including loans held for investment, loans held for investment acquired through participation, obligations under participation agreements, mortgage loan payable, repurchase agreement payable and revolving credit facility payable. Such financial instruments are carried at cost, less impairment, where applicable. Marketable securities are financial instruments that are reported at fair value. Fair Value Measurement (“ASC 820”), which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 established a fair value hierarchy that prioritizes and ranks the level of market price observability used in measuring investments at fair value. Market price observability is impacted by a number of factors, including the type of investment, the characteristics specific to the investment, and the state of the marketplace (including the existence and transparency of transactions between market participants). Investments with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in an orderly market will generally have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Investments measured and reported at fair value are classified and disclosed into one of the following categories based on the inputs as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets and liabilities that the Company has the ability to access. Level 2 — Pricing inputs are other than quoted prices in active markets, including, but not limited to, quoted prices for similar assets and liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs. Level 3 — Significant unobservable inputs are based on the best information available in the circumstances, to the extent observable inputs are not available, including the Company’s own assumptions used in determining the fair value of investments. Fair value for these investments are determined using valuation methodologies that consider a range of factors, including but not limited to the price at which the investment was acquired, the nature of the investment, local market conditions, trading values on public exchanges for comparable securities, current and projected operating performance, and financing transactions subsequent to the acquisition of the investment. The inputs into the determination of fair value require significant management judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. As of September 30, 2020 and December 31, 2019, the Company has not elected the fair value option for its financial instruments, including loans held for investment, loans held for investment acquired through participation, obligations under participation agreements, term loan payable, mortgage loan payable, repurchase agreement payable and revolving credit facility payable. Such financial instruments are carried at cost, less impairment or less net deferred costs , where applicable. Marketable securities are financial instruments that are reported at fair value.
Deferred Financing Costs Policy	Deferred Financing Costs    Deferred financing costs represent fees and expenses incurred in connection with obtaining financing for investments. These costs are presented in the consolidated balance sheets as a direct deduction of the debt liability to which the costs pertain. These costs are amortized using the effective interest method and are included in interest expense on the applicable borrowings in the consolidated statements of operations over the life of the borrowings.
Income Tax Policy	Income Taxes The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code commencing with the taxable year ended December 31, 2016. In order to qualify as a REIT, the Company is required, among other things, to distribute at least 90% of its REIT net taxable income to the stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income taxes on income and gains distributed to the stockholders as long as certain requirements are satisfied, principally relating to the nature of income and the level of distributions, as well as other factors. 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 (including any applicable alternative minimum tax for taxable years before 2018) 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. Any gains from the sale of foreclosed properties within two years are subject to U.S. federal and state income taxes at regular corporate rates. As of September 30, 2020, the Company has satisfied all the requirements for a REIT. No provision for federal income taxes has been included in the consolidated financial statements for the three and nine months ended September 30, 2020 and 2019. The Company did not have any uncertain tax positions that met the recognition or measurement criteria of Accounting Standards Codification (“ASC”) 740-10-25, Income Taxes
Earnings Per Share Policy	Earnings Per Share The Company has a simple equity capital structure with only common stock and preferred stock outstanding. As a result, earnings per share, as presented, represent both basic and dilutive per-share amounts for the periods presented in the consolidated financial statements. Income per basic share of common stock is calculated by dividing net income allocable to common stock by the weighted-average number of shares of common stock issued and outstanding during such period.
Use of Estimates Policy	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. As of September 30, 2020, there has been an ongoing global outbreak of a novel coronavirus (“COVID-19”), which has spread to over 200 countries and territories, including the United States, and has spread to every state in the United States. The World Health Organization has designated COVID-19 as a pandemic, and numerous countries, including the United States, have declared national emergencies with respect to COVID-19. The global impact of the outbreak has been rapidly evolving, and as cases of COVID-19 have continued to be identified in additional countries, many countries have reacted by instituting quarantines and restrictions on travel, closing financial markets and/or restricting trading and operations of non-essential offices and retail centers. Such actions are creating disruption in global supply chains, and adversely impacting many industries. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions. The Company believes the estimates and assumptions underlying its consolidated financial statements are reasonable and supportable based on the information available as of September 30, 2020, however uncertainty over the ultimate impact COVID-19 will have on the global economy generally, and the Company’s business in particular, makes any estimates and assumptions as of September 30, 2020 inherently less
Segment Reporting Policy	Segment Information    The Company’s primary business is originating, acquiring and structuring real estate-related loans related to high quality commercial real estate. From time to time, the Company may acquire real estate encumbering the senior loans through foreclosure. However, management treats the operations of the real estate acquired through foreclosure as the continuation of the original senior loans. The Company operates in a single segment focused on mezzanine loans, other loans and preferred equity investments, and to a lesser extent, owning and managing real estate.
New Accounting Pronouncements Policy	Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“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 introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. In April 2019, the FASB issued additional amendments to clarify the scope of ASU 2016-13 and address issues related to accrued interest receivable balances, recoveries, variable interest rates and prepayments, among other things. In May 2019, the FASB issued ASU 2019-05 — Targeted Transition Relief, which provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. In October 2019, the FASB decided that for smaller reporting companies, ASU 2016-13 and related amendments will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company meets the definition of a smaller reporting company under the regulation of the Securities and Exchange Commission. As such, the Company will adopt this ASU and related amendments on January 1, 2023. Management is currently evaluating the impact this change will have on the Company’s consolidated financial statements and disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure framework — Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The objective of ASU 2018-13 is to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of information required by U.S. GAAP. The amendments in ASU 2018-13 added, removed and modified certain fair value measurement disclosure requirements. ASU 2018-13 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 on January 1, 2020. The adoption of ASU 2018-13 did not have a material impact on its consolidated financial statements and disclosures. London Interbank Offered Rate (“LIBOR”) is a benchmark interest rate referenced in a variety of agreements that are used by all types of entities. At the end of 2021, banks will no longer be required to report information that is used to determine LIBOR. As a result, LIBOR could be discontinued. Other interest rates used globally could also be discontinued for similar reasons. 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”). The amendments in ASU 2020-04 provide companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. The provisions of optional relief include: (i) contract modifications - account for the modification as a continuation of the existing contract without additional analysis; (ii) hedging accounting - continue hedge accounting when certain critical terms of a hedging relationship change; and (iii) held-to-maturity (HTM) debt securities - one-time sale and/or transfer to available for sale or trading may be made for HTM debt securities that both reference an eligible reference rate and were classified as HTM before January 1, 2020. Companies can apply the amendments in ASU 2020-04 immediately. However, ASU 2020-04 will only be available for a limited time (generally through December 31, 2022). The Company is currently evaluating the impact of the reference rate reform and ASU 2020-04 on its consolidated financial statements and disclosures.

Loan Risk Rating As described in Note 2 , the Manager evaluates the Company’s loan portfolio on a quarterly basis or more frequently as needed. In conjunction with the quarterly review of the Company’s loan portfolio, the Manager assesses the risk factors of each loan, and assigns a risk rating based on a five-point scale with “1” being the lowest risk and “5” being the greatest risk. The following table allocates the principal balance and the carrying value of the Company’s loans based on the loan risk rating as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 Loan Risk Rating Number of Loans Principal Balance Carrying Value % of Total Number of Loans Principal Balance Carrying Value % of Total 1 0 $ — $ — — % — $ — $ — — % 2 2 24,000,000 24,170,000 5.5 % 5 50,000,000 50,284,751 13.3 % 3 14 322,901,131 324,464,200 73.9 % 17 322,648,317 323,588,017 85.4 % 4 (1) 5 90,449,156 90,703,442 20.6 % — — — — % 5 0 — — — % — — — — % Other (2) 0 — — — % 1 4,740,000 4,740,000 1.3 % 21 $ 437,350,287 439,337,642 100.0 % 23 $ 377,388,317 378,612,768 100.0 % Allowance for loan losses (1,356,737) — Total, net of allowance for loan losses $ 437,980,905 $ 378,612,768 _______________ (1) The increase in number of loans with a loan risk rating of “4” was due to the higher risk in loans collateralized by hospitality and select other asset classes that are particularly negatively impacted by the COVID-19 pandemic. (2) This loan was deemed impaired and removed from the pool of loans on which a general allowance is calculated. As of December 31, 2019, no specific reserve for loan losses was recorded on this loan because the fair value of the collateral was greater than carrying value of the loan.

Debt Instrument, Covenant Description		On June 20, 2019, Terra LOC Portfolio I, LLC, a special-purpose indirect wholly-owned subsidiary of the Company, entered into a credit agreement with Israel Discount Bank of New York to provide for revolving credit loans of up to $35.0 million in the aggregate (“Revolving Credit Facility”), which the Company expects to use for short term financing needed to bridge the timing of anticipated loans repayments and funding obligations. Borrowings under the Revolving Credit Facility can be either prime rate loans or LIBOR rate loans and accrue interest at an annual rate of prime rate plus 1% or LIBOR plus 4% with a floor of 6%. Each loan made under the Revolving Credit Facility shall be in a minimum aggregate principal amount of the lesser of $1.0 million or the then unused amount under the facility and cannot be more than $25.0 million in the aggregate with respect to each asset purchased with the proceeds from the Revolving Credit Facility. The Revolving Credit Facility was scheduled to mature on June 20, 2020. The Revolving Credit Facility was amended to extend the maturity to September 3, 2020. The Company is currently negotiating with the lender to extend the maturity of the Revolving Credit Facility by a year and the lender has waived the maturity default. In connection with obtaining the Revolving Credit Facility, the Company incurred deferred financing costs of $0.3 million, which was amortized over the original term of the facility.
