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, 2017, except for the Company’s adoption of the revenue recognition standards issued by the Financial Accounting Standards Board (“FASB”) effective on January 1, 2018. 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, 2017 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “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 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, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The consolidated financial statements include the accounts of the Company, KBS REIT Holdings II, 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 condensed notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and condensed notes. Actual results could materially differ from those estimates. 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 during the three months ended March 31, 2018 and 2017, respectively. Distributions declared per common share were $0.060 and $0.068 in the aggregate for the three months ended March 31, 2018 and 2017, respectively. Distributions declared per common share assumes each share was issued and outstanding each day that was a record date for distributions and were based on a monthly record date for each month during the periods commencing January 2018 through March 2018 and January 2017 through March 2017. Segments The Company invested in core real estate properties and real estate-related investments with the goal of acquiring a portfolio of income-producing investments. The Company’s real estate properties exhibit similar long-term financial performance and have similar economic characteristics to each other. Beginning with the reporting period commencing on January 1, 2016, the Company aggregated its investments into one reportable business segment. The Company considered both quantitative and qualitative thresholds and determined that its investment in a real estate loan receivable does not constitute a reportable segment. Prior to the reporting period commencing on January 1, 2016, the Company had identified two reportable business segments based on its investment types: real estate and real estate-related. However, based on the Company’s current investment portfolio, the Company does not believe that its investment in a real estate-related investment is a reportable segment. Reclassifications Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have not changed the results of operations of prior periods. During the three months ended March 31, 2018, the Company classified two office buildings that are part of an eight-building office campus as held for sale. As a result, certain assets and liabilities were reclassified to held for sale on the consolidated balance sheets for all periods presented. Revenue Recognition Effective January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU No. 2014-09”), using the modified retrospective approach, which requires a cumulative effect adjustment as of the date of the Company’s adoption. Under the modified retrospective approach, an entity may also elect to apply this standard to either (i) all contracts as of January 1, 2018 or (ii) only to contracts that were not completed as of January 1, 2018. A completed contract is a contract for which all (or substantially all) of the revenue was recognized under legacy GAAP that was in effect before the date of initial application. The Company elected to apply this standard only to contracts that were not completed as of January 1, 2018. Based on the Company’s evaluation of contracts within the scope of ASU No. 2014-09, revenue that is impacted by ASU No. 2014-09 includes revenue generated by sales of real estate, other operating income and tenant reimbursements for substantial services earned at the Company’s properties. The recognition of such revenue will occur when the services are provided and the performance obligations are satisfied. For the three months ended March 31, 2018, tenant reimbursements for substantial services accounted for under ASU No. 2014-09 was $0.4 million and was included in tenant reimbursements on the accompanying statements of operations. Sales of Real Estate Prior to January 1, 2018, gains on real estate sold were recognized using the full accrual method at closing when collectibility of the sales price was reasonably assured, the Company was not obligated to perform additional activities that may be considered significant, the initial investment from the buyer was sufficient and other profit recognition criteria had been satisfied. Gain on sales of real estate may have been deferred in whole or in part until the requirements for gain recognition had been met. Effective January 1, 2018, the Company adopted the guidance of ASC 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (“ASC 610-20”), which applies to sales or transfers to noncustomers of nonfinancial assets or in substance nonfinancial assets that do not meet the definition of a business. Generally, the Company’s sales of real estate would be considered a sale of a nonfinancial asset as defined by ASC 610-20. ASC 610-20 refers to the revenue recognition principles under ASU No. 2014-09. Under ASC 610-20, if the Company determines it does not have a controlling financial interest in the entity that holds the asset and the arrangement meets the criteria to be accounted for as a contract, the Company would derecognize the asset and recognize a gain or loss on the sale of the real estate when control of the underlying asset transfers to the buyer. Square Footage, Occupancy and Other Measures Square footage, occupancy, number of tenants and other similar measures, including annualized base rent and annualized base rent per square foot, used to describe real estate and real estate-related investments included in these condensed notes to the consolidated financial statements are unaudited 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 February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU No. 2016-02”). The amendments in ASU No. 2016-02 change the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. The standard requires lessors to identify lease and non-lease components under their leasing arrangements and allocate the total consideration in the lease agreement to these lease and non-lease components based on their relative standalone selling prices. Non-lease components will be subject to the new revenue recognition standard upon the Company’s adoption of the new leasing standard on January 1, 2019. ASU No. 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of ASU No. 2016-02 as of its issuance is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. In March 2018, the FASB affirmed a proposed amendment to the leases ASU, which would add a transition option to the new leases standard that would allow entities to apply the transition provisions of the new standard at its adoption date instead of the earliest comparative periods presented in its financial statements. The FASB also tentatively approved a practical expedient that would permit lessors to not separate lease and non-lease components if certain conditions are met. The Company is currently evaluating the impact of adopting the new leases standard on its consolidated financial statements and if adopted by the FASB, applying the transition option and electing the practical expedient of the proposed amendment. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments (“ASU No. 2016-13”). ASU No. 2016-13 affects entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. The amendments in ASU No. 2016-13 require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. ASU No. 2016-13 also amends the impairment model for available-for-sale securities. An entity will recognize an allowance for credit losses on available-for-sale debt securities as a contra-account to the amortized cost basis rather than as a direct reduction of the amortized cost basis of the investment, as is currently required. ASU No. 2016-13 also requires new disclosures. For financial assets measured at amortized cost, an entity will be required to disclose information about how it developed its allowance for credit losses, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. For financing receivables and net investments in leases measured at amortized cost, an entity will be required to further disaggregate the information it currently discloses about the credit quality of these assets by year of the asset’s origination for as many as five annual periods. For available for sale securities, an entity will be required to provide a roll-forward of the allowance for credit losses and an aging analysis for securities that are past due. ASU No. 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is still evaluating the impact of adopting ASU No. 2016-13 on its financial statements, but does not expect the adoption of ASU No. 2016-13 to have a material impact on its financial statements.

Use of Estimates

The preparation of the consolidated financial statements and condensed notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and condensed notes. Actual results could materially differ from those estimates.

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 during the three months ended March 31, 2018 and 2017, respectively.

Distributions declared per common share were $0.060 and $0.068 in the aggregate for the three months ended March 31, 2018 and 2017, respectively.

Under the modified retrospective approach, an entity may also elect to apply this standard to either (i) all contracts as of January 1, 2018 or (ii) only to contracts that were not completed as of January 1, 2018. A completed contract is a contract for which all (or substantially all) of the revenue was recognized under legacy GAAP that was in effect before the date of initial application. The Company elected to apply this standard only to contracts that were not completed as of January 1, 2018.
