Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION KBS Growth & Income REIT, Inc. (the “Company”) was formed on January 12, 2015 as a Maryland corporation that elected to be taxed as a real estate investment trust (“REIT”) beginning with the taxable year ended December 31, 2015. Substantially all of the Company’s business is conducted through KBS Growth & Income Limited Partnership (the “Operating Partnership”), a Delaware limited partnership formed on January 14, 2015. The Company is the sole general partner of, and owns a 0.1% partnership interest in, the Operating Partnership. KBS Growth & Income REIT Holdings LLC (“REIT Holdings”), a Delaware limited liability company formed on January 14, 2015, owns the remaining 99.9% partnership interest in the Operating Partnership and is the sole limited partner. The Company is the sole member and manager of REIT Holdings. Subject to certain restrictions and limitations, the business of the Company is externally managed by KBS Capital Advisors LLC (the “Advisor”), an affiliate of the Company, pursuant to an advisory agreement between the Company and the Advisor initially entered into on June 11, 2015, and amended at various times thereafter (the “Advisory Agreement”). The Advisor conducts the Company’s operations and manages its portfolio of core real estate properties. On January 27, 2015, the Company issued 20,000 shares of its common stock to the Advisor at a purchase price of $10.00 per share. On June 11, 2015, these outstanding shares of common stock were designated Class A shares of common stock. As of March 31, 2022, the Company had invested in four office properties. The Company has invested in a portfolio of core real estate properties. The Company considers core properties to be existing properties with at least 80% occupancy. The Company commenced capital raising activities in June 2015 through a private placement offering. The private offering was followed by a public offering and a second private offering. In August 2020, the Company’s board of directors approved the termination of capital raising activities with the termination of the Company’s distribution reinvestment plan offering and second private offering. As of March 31, 2022, the Company had 9,851,052 and 310,974 Class A and Class T shares outstanding, respectively. COVID-19 Pandemic One of the most significant risks and uncertainties facing the Company and the real estate industry generally, and in particular office REITs like the Company, continues to be the effect of the public health crisis of the novel coronavirus disease (“COVID-19”) pandemic. The Company recognized impairment charges related to a projected reduction in cash flows as a result of changes in leasing projections that were impacted in part by the COVID-19 pandemic at the Institute Property and 210 W. Chicago during the year ended December 31, 2020, the Commonwealth Building during the year ended December 31, 2021, and the Commonwealth Building and the Institute Property during the three months ended March 31, 2022. The extent to which the COVID-19 pandemic impacts the Company’s operations and those of its tenants and the Company’s implementation of a Plan of Liquidation (defined below) depends on future developments, which remain uncertain and cannot be predicted with confidence, including, among other developments, potential changes in customer behavior, such as the continued social acceptance, desirability and perceived economic benefits of work-from-home arrangements, resulting from the COVID-19 pandemic, which could materially and negatively impact the future demand for office space, resulting in slower overall leasing and an adverse impact to our operations. Plan of Liquidation The Company’s board of directors and a special committee composed of all of the Company’s independent directors (the “Special Committee”) has undertaken a review of various strategic alternatives available to the Company and expects to approve the sale of all of the Company’s assets and the Company’s dissolution pursuant to the terms of a plan of complete liquidation and dissolution (a “Plan of Liquidation”). Once approved by the Company’s board of directors, a Plan of Liquidation will be submitted to the Company’s stockholders for approval. The Advisor has been working diligently to develop a Plan of Liquidation to present to the Company’s Special Committee and Board of Directors for approval; however, the impact of the COVID-19 pandemic on a Plan of Liquidation for the Company’s portfolio, as well as the decreased demand for office space as employees continue to work from home, the rise in interest rates that is impacting the ability of buyers to obtain favorable financing and continued social unrest and increased crime in the Portland area where one of the Company’s properties is located, have created significant headwinds to finalizing a Plan of Liquidation. The principal purpose of a Plan of Liquidation will be to provide liquidity to the Company’s stockholders by selling the Company’s assets, paying its debts and distributing the net proceeds from liquidation to the Company’s stockholders. Although this is the current intention of the Company’s board of directors, the Company can provide no assurances as to the ultimate approval of a Plan of Liquidation or the timing of the liquidation of the Company. If the Company’s board of directors and stockholders approve a Plan of Liquidation, the Company intends to pursue an orderly liquidation of its company by selling all of its remaining assets, paying its debts and its known liabilities, providing for the payment of unknown or contingent liabilities, distributing the net proceeds from liquidation to the Company’s stockholders and winding up its operations and dissolving its company. In the interim, the Company intends to continue to manage its portfolio of assets to maintain and, if possible, improve the quality and income-producing ability of its properties to enhance property stability and better position the Company’s assets for a potential sale. A Plan of Liquidation remains subject to approval by the Company’s board of directors and the Company’s stockholders and the Company can give no assurance regarding the timing of the liquidation of the Company. Additional information regarding a Plan of Liquidation will be provided to the Company’s stockholders in a proxy statement to be distributed to stockholders in connection with a liquidation vote.

GOING CONCERN

GOING CONCERN	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
GOING CONCERN	GOING CONCERNThe consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its obligations and continue its operations one year from the date the consolidated financial statements are issued. The Company has experienced a decline in occupancy from 90.4% as of December 31, 2020 to 77.5% as of March 31, 2022 and such occupancy may continue to decrease in the future as tenant leases expire. The decrease in occupancy has resulted in a decrease in cash flow from operations and has negatively impacted the market values of the properties. Additionally, the Company has two loans with an aggregate principal balance of $97.9 million maturing within one year from the date the consolidated financial statements are issued. Due to the decrease in occupancies and a decrease in market values of the properties securing these two loans, the Company may be unable to extend or refinance the upcoming loan maturities at current terms and may be required to paydown a portion of the maturing debt in order to extend or refinance the loans. With the Company’s limited amount of cash on hand, the Company’s ability to make any loan paydowns, without the sale of real estate assets, is severely limited. Additionally, in order to attract or retain tenants needed to increase occupancy and sustain operations, the Company will need to spend a substantial amount on capital leasing costs, however, the Company has limited amounts of liquidity to make these capital commitments. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments to reflect the outcome of these uncertainties. The Company’s ability to continue as a going concern is dependent upon the Company’s ability to exercise its extension option or refinance loans maturing over the next 12 months. No assurances can be given that the Company will be successful in achieving these objectives. In addition, as described in Note 1, “Organization – Plan of Liquidation”, if the Company’s board of directors and its stockholders approve a Plan of Liquidation, the Company intends to pursue an orderly liquidation of its company by selling all of its remaining assets, paying its debts and its known liabilities, providing for the payment of unknown or contingent liabilities, distributing the net proceeds from liquidation to the Company’s stockholders and winding up its operations and dissolving the company.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES There have been no significant changes to the Company’s accounting policies since it filed its audited financial statements in its Annual Report on Form 10-K for the year ended December 31, 2021. For further information about the Company’s accounting policies, refer to the Company’s consolidated financial statements and notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). Principles of Consolidation and Basis of Presentation The accompanying unaudited consolidated financial statements and condensed notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC, including the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the financial statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The consolidated financial statements include the accounts of the Company, REIT Holdings, the Operating Partnership, and their direct and indirect wholly owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements and the accompanying notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. Segments The Company had invested in four office properties as of March 31, 2022. Substantially all of the Company’s revenue and net loss is from real estate, and therefore, the Company currently operates in one reportable segment. Per Share Data Basic net income (loss) per share of common stock is calculated by dividing net income (loss) by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted net income (loss) per share of common stock equals basic net income (loss) per share of common stock as there were no potentially dilutive securities outstanding for the three months ended March 31, 2022 and 2021. Basic and diluted net income (loss) per share of Class A common stock and basic and diluted net income (loss) per share of Class T common stock were equal for the three months ended March 31, 2022 and 2021 as aggregate cash distributions for each share class were equal during those periods. During the three months ended March 31, 2021, aggregate cash distributions declared per share of Class A and Class T common stock were $0.04287500, assuming the share was issued and outstanding each date that was a record date for distributions during the period. Square Footage, Occupancy and Other Measures Square footage, occupancy, number of tenants and other measures, including annualized base rent and annualized base rent per square foot, or amounts derived from such measures, used to describe real estate investments included in these condensed notes to consolidated financial statements are presented on an unaudited basis and outside the scope of the Company’s independent registered public accounting firm’s review of the Company’s financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board. Recently Issued Accounting Standards Update In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU No. 2020-04”) to provide temporary optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). Modified contracts that meet the following criteria are eligible for relief from the modification accounting requirements under GAAP: (1) The contract references LIBOR or another rate that is expected to be discontinued due to reference rate reform, (2) The modified terms directly replace or have the potential to replace the reference rate that is expected to be discontinued due to reference rate reform, and (3) Any contemporaneous changes to other terms (i.e., those that do not directly replace or have the potential to replace the reference rate) that change or have the potential to change the amount and timing of contractual cash flows must be related to the replacement of the reference rate. For a contract that meets the criteria, the guidance generally allows an entity to account for and present modifications as an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. That is, the modified contract is accounted for as a continuation of the existing contract. In addition, ASU No. 2020-04 provides various optional expedients for hedging relationships affected by reference rate reform, if certain criteria are met. The amendments in ASU No. 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic, the amendments in this Update must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. An entity may elect to apply the amendments in ASU No. 2020-04 to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020.

Operating Leases The Company’s real estate properties are leased to tenants under operating leases for which the terms and expirations vary. As of March 31, 2022, the leases had remaining terms, excluding options to extend, of up to 8.9 years with a weighted-average remaining term of 3.5 years. Some of the leases have provisions to extend the term of the leases, options for early termination for all or a part of the leased premises after paying a specified penalty, and other terms and conditions as negotiated. The Company retains substantially all of the risks and benefits of ownership of the real estate assets leased to tenants. Generally, upon the execution of a lease, the Company requires a security deposit from the tenant in the form of a cash deposit and/or a letter of credit. The amount required as a security deposit varies depending upon the terms of the respective lease and the creditworthiness of the tenant, but generally is not a significant amount. Therefore, exposure to credit risk exists to the extent that a receivable from a tenant exceeds the amount of its security deposit. Security deposits received in cash related to tenant leases are included in other liabilities in the accompanying consolidated balance sheets and totaled $0.9 million and $0.7 million as of March 31, 2022 and December 31, 2021, respectively. During the three months ended March 31, 2022 and 2021, the Company recognized deferred rent from tenants, net of lease incentive amortization, of $0.2 million and $(0.1) million, respectively. As of March 31, 2022 and December 31, 2021, the cumulative deferred rent balance was $4.3 million and $4.1 million, respectively, and is included in rents and other receivables on the accompanying consolidated balance sheets. The cumulative deferred rent balance included $1.9 million and $1.9 million of unamortized lease incentives as of March 31, 2022 and December 31, 2021, respectively. As of March 31, 2022, the future minimum rental income from the Company’s properties under its non-cancelable operating leases was as follows (in thousands): April 1, 2022 through December 31, 2022 $ 7,949 2023 10,336 2024 9,344 2025 6,332 2026 5,879 Thereafter 11,376 $ 51,216 As of March 31, 2022, the Company had a concentration of credit risk related to AECOM, one of the tenants in The Offices at Greenhouse in the engineering industry, which represented 24% of the Company’s annualized base rent. The tenant individually occupied 135,727 rentable square feet or approximately 23% of the total rentable square feet of the Company’s real estate portfolio, which expires on December 31, 2024, with two five As of March 31, 2022, the Company’s real estate properties were leased to 54 tenants over a diverse range of industries. The Company’s highest tenant industry concentration (greater than 10% of annualized base rent) was as follows: Industry Number of Tenants Annualized Base Rent (1) (in thousands) Percentage of Annualized Base Rent Professional, scientific and technical 8 $ 4,481 37.6 % Computer system design and related services 3 1,380 11.6 % $ 5,861 49.2 % _____________________ (1) Annualized base rent represents annualized contractual base rental income as of March 31, 2022, adjusted to straight-line any contractual tenant concessions (including free rent), rent increases and rent decreases from the lease’s inception through the balance of the lease term. As of March 31, 2022, no other tenant industries accounted for more than 10% of annualized base rent. Impairment of Real Estate During the three months ended March 31, 2022, the Company recorded non-cash impairment charges of $3.3 million to write down the carrying values of the Commonwealth Building, an office property located in Portland, Oregon and the Institute Property, an office property located in Chicago, Illinois, to their estimated fair values as follows: • Commonwealth Building - The impairment was as a result of a continued decrease in occupancy and changes in cash flow estimates including a change in leasing projections, which triggered the future estimated undiscounted cash flows to be lower than the net carrying value of the property. As of March 31, 2022, the Commonwealth Building was 51.8% occupied. The Company is projecting longer lease-up periods for the vacant space as demand for office space in Portland has significantly declined as a result of both the COVID-19 pandemic, with employees continuing to work from home, and the impact of the disruptions caused by protests and demonstrations and increased crime in the downtown area. Downtown Portland is experiencing record high office vacancies and it is uncertain when the market will fully recover. • Institute Property - The impairment was as a result of changes in cash flow estimates including a change in leasing projections, which triggered the future estimated undiscounted cash flows to be lower than the net carrying value of the property. The decrease in cash flow projections was primarily due to reduced demand for the office space at the property resulting in longer lease-up periods and a decrease in projected rental rates due to the COVID-19 pandemic which resulted in additional challenges to re-lease the vacant space. Further, tenants at the Institute Property have been adversely impacted by the measures put in place to control the spread of COVID-19 and certain tenants at the Institute Property were granted rent concessions as their businesses have been severely impacted. The Company did not record any impairment charges on its real estate properties during the three months ended March 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTShe Company enters into derivative instruments for risk management purposes to hedge its exposure to cash flow variability caused by changing interest rates. The primary goal of the Company’s risk management practices related to interest rate risk is to prevent changes in interest rates from adversely impacting the Company’s ability to achieve its investment return objectives. The Company does not enter into derivatives for speculative purposes. The Company enters into interest rate swaps as a fixed rate payer to mitigate its exposure to rising interest rates on its variable rate notes payable. The value of interest rate swaps is primarily impacted by interest rates, market expectations about interest rates, and the remaining life of the instrument. In general, increases in interest rates, or anticipated increases in interest rates, will increase the value of the fixed rate payer position and decrease the value of the variable rate payer position. As the remaining term of the interest rate swap decreases, the value of both positions will generally move towards zero. The following table summarizes the notional amount and other information related to the Company’s interest rate swap as of March 31, 2022 and December 31, 2021. The notional amount is an indication of the extent of the Company’s involvement in each instrument at that time, but does not represent exposure to credit, interest rate or market risks (dollars in thousands): March 31, 2022 December 31, 2021 Reference Rate as of March 31, 2022 Fix Pay Rate as of March 31, 2022 Remaining Term in Years as of March 31, 2022 Derivative Instruments Number of Instruments Notional Amount Number of Instruments Notional Amount Derivative instruments not designated as hedging instruments Interest Rate Swap 1 $ 30,000 1 $ 30,000 One-month LIBOR/ Fixed at 2.82% 2.82% 0.6 The following table sets forth the fair value of the Company’s derivative instruments as well as their classification on the consolidated balance sheets as of March 31, 2022 and December 31, 2021 (dollars in thousands): March 31, 2022 December 31, 2021 Derivative Instruments Balance Sheet Location Number of Instruments Fair Value Number of Instruments Fair Value Derivative instruments not designated as hedging instruments Interest Rate Swap Other liabilities, at fair value 1 $ (269) 1 $ (610) The change in fair value of a derivative instrument that is not designated as a cash flow hedge is included in interest expense in the accompanying consolidated statements of operations.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES Under GAAP, the Company is required to measure certain financial instruments at fair value on a recurring basis. In addition, the Company is required to measure other non-financial and financial assets at fair value on a non-recurring basis (e.g., carrying value of long-lived assets). Fair value, as defined under GAAP, is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories: • Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; • Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and • Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable. The fair value for certain financial instruments is derived using a combination of market quotes, pricing models and other valuation techniques that involve significant management judgment. The price transparency of financial instruments is a key determinant of the degree of judgment involved in determining the fair value of the Company’s financial instruments. Financial instruments for which actively quoted prices or pricing parameters are available and for which markets contain orderly transactions will generally have a higher degree of price transparency than financial instruments for which markets are inactive or consist of non-orderly trades. The Company evaluates several factors when determining if a market is inactive or when market transactions are not orderly. The following is a summary of the methods and assumptions used by management in estimating the fair value of each class of financial instrument for which it is practicable to estimate the fair value: Cash and cash equivalents, restricted cash, rent and other receivables, and accounts payable and accrued liabilities: These balances approximate their fair values due to the short maturities of these items. Derivative instruments: The Company’s derivative instruments are presented at fair value on the accompanying consolidated balance sheets. The valuation of these instruments is determined using a proprietary model that utilizes observable inputs. As such, the Company classifies these inputs as Level 2 inputs. The proprietary model uses the contractual terms of the derivatives, including the period to maturity, as well as observable market-based inputs, including interest rate curves and volatility. The fair values of interest rate swaps are estimated using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit risks to the contracts, are incorporated in the fair values to account for potential nonperformance risk. Notes payable: The fair value of the Company’s notes payable is estimated using a discounted cash flow analysis based on management’s estimates of current market interest rates for instruments with similar characteristics, including remaining loan term, loan-to-value ratio, type of collateral and other credit enhancements. Additionally, when determining the fair value of liabilities in circumstances in which a quoted price in an active market for an identical liability is not available, the Company measures fair value using (i) a valuation technique that uses the quoted price of the identical liability when traded as an asset or quoted prices for similar liabilities when traded as assets or (ii) another valuation technique that is consistent with the principles of fair value measurement, such as the income approach or the market approach. The Company classifies these inputs as Level 3 inputs. The following were the face values, carrying amounts and fair values of the Company’s notes payable as of March 31, 2022 and December 31, 2021, which carrying amounts generally do not approximate the fair values (in thousands): March 31, 2022 December 31, 2021 Face Value Carrying Amount Fair Value Face Value Carrying Amount Fair Value Financial liabilities: Notes payable $ 101,648 $ 101,491 $ 100,411 $ 101,666 $ 101,454 $ 100,367 Disclosure of the fair values of financial instruments is based on pertinent information available to the Company as of the period end and requires a significant amount of judgment. The actual value could be materially different from the Company’s estimate of value. As of March 31, 2022, the Company measured the following derivative instruments at fair value (in thousands): Fair Value Measurements Using Total Quoted Prices in Active Markets Significant Other Observable Inputs Significant Unobservable Inputs Recurring Basis: Liability derivative - interest rate swap $ (269) $ — $ (269) $ — During the three months ended March 31, 2022, the Company measured the following asset at fair value on a nonrecurring basis (in thousands): Fair Value Measurements Using Total Quoted Prices in Active Markets Significant Other Observable Inputs Significant Unobservable Inputs Nonrecurring Basis: Impaired real estate $ 81,500 $ — $ — $ 81,500 During the three months ended March 31, 2022, the Commonwealth Building and the Institute Property were measured at their estimated fair values based on a discounted cash flow approach. The significant unobservable inputs the Company used in measuring the estimated fair value of the Commonwealth Building include a discount rate of 8.25% and a terminal cap rate of 6.25% and the significant unobservable inputs the Company used in measuring the estimated fair value of the Institute Property include a discount rate of 7.50% and a terminal cap rate of 6.50%.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS Pursuant to the Advisory Agreement, the Company is obligated to pay the Advisor specified fees upon the provision of certain services related to the management of the Company’s investments and for other services (including, but not limited to, the disposition of investments). The Company is also obligated to reimburse the Advisor for certain operating expenses incurred on behalf of the Company or incurred in connection with providing services to the Company. The Advisor is entitled to certain other fees, including an incentive fee upon achieving certain performance goals, as detailed in the Advisory Agreement. In addition, the Advisor has paid all offering expenses related to the second private offering conducted by the Company without reimbursement by the Company. In addition, in connection with property acquisitions, the Company, through indirect wholly owned subsidiaries, has entered into separate Property Management Agreements (defined below) with KBS Management Group, LLC, an affiliate of the Advisor (the “Co-Manager”). The Company has also entered into a fee reimbursement agreement with the Dealer Manager pursuant to which the Company agreed to reimburse the Dealer Manager for certain fees and expenses it incurs for administering the Company’s participation in the DTCC Alternative Investment Product Platform with respect to certain accounts of the Company’s investors serviced through the platform. The Advisor also serves as the advisor for KBS Real Estate Investment Trust II, Inc. (“KBS REIT II”) and KBS Real Estate Investment Trust III, Inc. (“KBS REIT III”). The Dealer Manager also serves as the dealer manager for KBS REIT II and KBS REIT III. As of January 1, 2021, the Company, together with KBS REIT II, KBS REIT III, the Dealer Manager, the Advisor and other KBS affiliated entities, had entered into an errors and omissions and directors and officers liability insurance program where the lower tiers of such insurance coverage were shared. The cost of these lower tiers is allocated by the Advisor and its insurance broker among each of the various entities covered by the program and is billed directly to each entity. In June 2021, the Company renewed its participation in the program. The program is effective through June 30, 2022. During the three months ended March 31, 2022 and 2021, no other business transactions occurred between the Company and KBS REIT II and KBS REIT III. Pursuant to the terms of these agreements, summarized below are the related-party costs incurred by the Company for the three months ended March 31, 2022 and 2021, and any related amounts receivable and payable as of March 31, 2022 and December 31, 2021 (in thousands).

As of March 31, 2022, the Company had accrued and deferred payment of $8.1 million of asset management fees related to the periods from October 2017 through March 2022. (2) See “Reimbursable Operating Expenses” below. (3) See “Real Estate Property Co-Management Agreements” below. (4) See “Advance from the Advisor” below. Reimbursable Operating Expenses Reimbursable operating expenses primarily related to directors and officers liability insurance, legal fees, state and local taxes, accounting software and cybersecurity related expenses incurred by the Advisor under the Advisory Agreement. The Company has reimbursed the Advisor for the Company’s allocable portion of the salaries, benefits and overhead of internal audit department personnel providing services to the Company. These amounts totaled $26,000 and $89,000 for the three months ended March 31, 2022 and 2021, respectively, and were the only type of employee costs reimbursed under the Advisory Agreement for the three months ended March 31, 2022 and 2021, respectively. The Company does not reimburse for employee costs in connection with services for which the Advisor earned or earns acquisition, origination or disposition fees (other than reimbursement of travel and communication expenses) or for the salaries or benefits the Advisor or its affiliates may pay to the Company’s executive officers. In addition to the amounts above, the Company reimburses the Advisor for certain of the Company’s direct costs incurred from third parties that were initially paid by the Advisor on behalf of the Company. The receivable as of March 31, 2022 and December 31, 2021 includes (i) $0.3 million of estimated amounts charged to the Company by certain vendors for services for which the Company believes it was either overcharged or which were never performed and (ii) $0.1 million of legal and accounting costs related to the investigation of this matter incurred during the three months ended March 31, 2022. The Advisor has agreed to reimburse the Company for any amounts inappropriately charged to the Company and for legal and accounting costs incurred related to the investigation of this matter. The Company’s audit committee is conducting an ongoing investigation of this matter. The Advisor must reimburse the Company the amount by which the Company’s aggregate total operating expenses for the four fiscal quarters then ended exceed the greater of 2% of the Company’s average invested assets or 25% of the Company’s net income, unless the conflicts committee has determined that such excess expenses were justified based on unusual and non-recurring factors. Operating expenses for the four fiscal quarters ended March 31, 2022 did not exceed the charter-imposed limitation. Advance from the Advisor The Advisor advanced funds to the Company, which are non-interest bearing, for distribution record dates through the period ended May 31, 2016. As of March 31, 2022, the total advanced funds due to the Advisor from the Company was approximately $1.3 million, which is included in due to affiliates in the Company’s consolidated balance sheet. The Company is only obligated to repay the Advisor for its advance if and to the extent that: (i) the Company’s modified funds from operations (“MFFO”), as such term is defined by the Institute for Portfolio Alternatives and interpreted by the Company, for the immediately preceding quarter exceeds the amount of cash distributions declared for record dates of such prior quarter (an “MFFO Surplus”), and the Company will pay the Advisor the amount of the MFFO Surplus to reduce the principal amount outstanding under the advance, provided that such payments shall only be made if management in its sole discretion expects an MFFO Surplus to be recurring for at least the next two calendar quarters, determined on a quarterly basis; (ii) Excess proceeds from third-party financings are available (“Excess Proceeds”), provided that the amount of any such Excess Proceeds that may be used to repay the principal amount outstanding under the advance shall be determined by the conflicts committee in its sole discretion; or (iii) Net sales proceeds from the sale of the Company’s real estate portfolio, after the pay down of any related debt and selling costs and expenses, are available. In determining whether Excess Proceeds are available to repay the advance, the Company’s conflicts committee will consider whether cash on hand could have been used to reduce the amount of third-party financing provided to the Company. If such cash could have been used instead of third-party financing, the third-party financing proceeds will be available to repay the advance. The Advisor may defer repayment of the advance notwithstanding that the Company would otherwise be obligated to repay the advance. Real Estate Property Co-Management Agreements In connection with its property acquisitions, the Company, through separate, indirect, wholly-owned subsidiaries, entered into separate property management agreements (each, a “Property Management Agreement”) with the Co-Manager for each of its properties. Under each Property Management Agreement, the Co-Manager will provide certain management services related to these properties in addition to those provided by the third-party property managers. In exchange for these services, the Company pays the Co-Manager a monthly fee equal to a percentage of the rent, payable and actually collected for the month from each of the properties. Each Property Management Agreement has an initial term of one year and will be deemed renewed for successive one Property Name Effective Date Annual Fee Percentage Commonwealth Building 07/01/2016 1.25% The Offices at Greenhouse 11/14/2016 0.25% Institute Property 11/09/2017 1.00% Organization and Offering Costs Offering costs include all expenses incurred in connection with the offerings of securities by the Company. Organization costs include all expenses incurred in connection with the formation of the Company, including but not limited to legal fees and other costs to incorporate the Company. The Advisor or its affiliates have paid some of the offering costs related to the Company’s distribution reinvestment plan offering (the “DRP”), including, but not limited to, legal, accounting, printing, mailing and filing fees of the Company. The Company was responsible for reimbursing the Advisor for these costs. No reimbursements made by the Company to the Advisor may cause total organization and offering expenses incurred by the Company to exceed 15% of the aggregate gross offering proceeds of the DRP as of the date of reimbursement. Subject to the limitations described above, the Company was also responsible for reimbursing the Dealer Manager or its affiliates for organization and offering expenses that they incurred on the Company’s behalf. On August 5, 2020, the Company’s board of directors approved the termination of the DRP effective August 20, 2020. From January 1, 2020 through August 20, 2020, with respect to the DRP, neither the Advisor nor the Dealer Manager incurred any organization and offering expenses on behalf of the Company. The Advisor agreed to pay all organization and offering expenses related to the second private offering conducted by the Company, including selling commissions, directly on behalf of the Company without reimbursement by the Company. From the inception of the offering through August 5, 2020, the Advisor incurred approximately $5.5 million of organization and offering expenses related to the second private offering on behalf of the Company. On August 5, 2020, the Company’s board of directors terminated the second private offering.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Economic Dependency The Company depends on the Advisor for certain services that are essential to the Company, including the management of the daily operations of the Company’s investment portfolio, disposition of investments and other general and administrative responsibilities. In the event that the Advisor is unable to provide such services, the Company will be required to obtain such services from other sources. Legal Matters From time to time, the Company may become party to legal proceedings that arise in the ordinary course of its business. Management is not aware of any legal proceedings of which the outcome is probable or reasonably possible to have a material adverse effect on the Company’s results of operations or financial condition, which would require accrual or disclosure of the contingency and possible range of loss. Additionally, the Company has not recorded any loss contingencies related to legal proceedings in which the potential loss is deemed to be remote. Environmental As an owner of real estate, the Company is subject to various environmental laws of federal, state and local governments. Although there can be no assurance, the Company is not aware of any environmental liability that could have a material adverse effect on its financial condition or results of operations. However, changes in applicable environmental laws and regulations, the uses and conditions of properties in the vicinity of the Company’s property, the activities of its tenants and other environmental conditions of which the Company is unaware with respect to the property could result in future environmental liabilities.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements and condensed notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC, including the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the financial statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.
Principles of Consolidation	The consolidated financial statements include the accounts of the Company, REIT Holdings, the Operating Partnership, and their direct and indirect wholly owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation.
Use of Estimates	The preparation of the consolidated financial statements and the accompanying notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates.
Segments	The Company had invested in four office properties as of March 31, 2022. Substantially all of the Company’s revenue and net loss is from real estate, and therefore, the Company currently operates in one reportable segment.
Per Share Data	Basic net income (loss) per share of common stock is calculated by dividing net income (loss) by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted net income (loss) per share of common stock equals basic net income (loss) per share of common stock as there were no potentially dilutive securities outstanding for the three months ended March 31, 2022 and 2021. Basic and diluted net income (loss) per share of Class A common stock and basic and diluted net income (loss) per share of Class T common stock were equal for the three months ended March 31, 2022 and 2021 as aggregate cash distributions for each share class were equal during those periods. During the three months ended March 31, 2021, aggregate cash distributions declared per share of Class A and Class T common stock were $0.04287500, assuming the share was issued and outstanding each date that was a record date for distributions during the period.
Square Footage, Occupancy and Other Measures	Square footage, occupancy, number of tenants and other measures, including annualized base rent and annualized base rent per square foot, or amounts derived from such measures, used to describe real estate investments included in these condensed notes to consolidated financial statements are presented on an unaudited basis and outside the scope of the Company’s independent registered public accounting firm’s review of the Company’s financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board.
Recently Issued Accounting Standards Updates	In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU No. 2020-04”) to provide temporary optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). Modified contracts that meet the following criteria are eligible for relief from the modification accounting requirements under GAAP: (1) The contract references LIBOR or another rate that is expected to be discontinued due to reference rate reform, (2) The modified terms directly replace or have the potential to replace the reference rate that is expected to be discontinued due to reference rate reform, and (3) Any contemporaneous changes to other terms (i.e., those that do not directly replace or have the potential to replace the reference rate) that change or have the potential to change the amount and timing of contractual cash flows must be related to the replacement of the reference rate. For a contract that meets the criteria, the guidance generally allows an entity to account for and present modifications as an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. That is, the modified contract is accounted for as a continuation of the existing contract. In addition, ASU No. 2020-04 provides various optional expedients for hedging relationships affected by reference rate reform, if certain criteria are met. The amendments in ASU No. 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic, the amendments in this Update must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. An entity may elect to apply the amendments in ASU No. 2020-04 to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020.
Fair Value Measurement	Under GAAP, the Company is required to measure certain financial instruments at fair value on a recurring basis. In addition, the Company is required to measure other non-financial and financial assets at fair value on a non-recurring basis (e.g., carrying value of long-lived assets). Fair value, as defined under GAAP, is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories: • Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; • Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and • Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable.
