Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and Description of Business Griffin-American Healthcare REIT III, Inc., a Maryland corporation, was incorporated on January 11, 2013 and therefore we consider that our date of inception. We were initially capitalized on January 15, 2013 . We invest in a diversified portfolio of real estate properties, focusing primarily on medical office buildings, hospitals, skilled nursing facilities, senior housing and other healthcare-related facilities. We also operate healthcare-related facilities utilizing the structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure (the provisions of the Internal Revenue Code of 1986, as amended, or the Code, authorizing the RIDEA structure were enacted as part of the Housing and Economic Recovery Act of 2008). We also originate and acquire secured loans and real estate-related investments on an infrequent and opportunistic basis. We generally seek investments that produce current income.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The summary of significant accounting policies presented below is designed to assist in understanding our accompanying condensed consolidated financial statements. Such condensed consolidated financial statements and the accompanying notes thereto are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to accounting principles generally accepted in the United States of America, or GAAP, in all material respects, and have been consistently applied in preparing our accompanying condensed consolidated financial statements. Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries in which we have control, as well as any variable interest entities, or VIEs, in which we are the primary beneficiary. We evaluate our ability to control an entity, and whether the entity is a VIE and we are the primary beneficiary, by considering substantive terms of the arrangement and identifying which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance as defined in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation , or ASC Topic 810. We operate and intend to co ntinue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries of which we have control, will own substantially all of the interests in properties acquired on our behalf. We are the sole general partner of o ur operating partnership, and as of June 30, 2017 and December 31, 2016 , we owned greater than a 99.99% general partnership interest therein. As of June 30, 2017 and December 31, 2016 , our advisor owned less than a 0.01% limited partnership interest in our operating partnership. Because we are the sole general partner of our operating partnership and have unilateral control over its management and major operating decisions (even if additional limited partners are admitted to our operating partnership), the accounts of our operating partnership are consolidated in our accompanying condensed consolidated financial statements. All intercompany accounts and transactions are eliminated in consolidation. Interim Unaudited Financial Data Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments which are, in our view, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such full year results may be less favorable. In preparing our accompanying condensed consolidated financial statements, management has evaluated subsequent events through the financial statement issuance date. We believe that although the disclosures contained herein are adequate to prevent the information presented from being misleading, our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2016 Annual Report on Form 10-K, as filed with the SEC on March 15, 2017. Use of Estimates The preparation of our accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions. Allowance for Uncollectible Accounts Tenant and resident receivables and unbilled deferred rent receivables are carried net of an allowance for uncollectible amounts. An allowance is maintained for estimated losses resulting from the inability of certain tenants or residents to meet the contractual obligations under their lease agreements. We also maintain an allowance for deferred rent receivables arising from the straight-line recognition of rents. Such allowances are charged to bad debt expense, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s or resident’s financial condition, security deposits, letters of credit, lease guarantees, current economic conditions and other relevant factors. As of June 30, 2017 and December 31, 2016 , we had $9,181,000 and $9,597,000 , respectively, in allowance for uncollectible accounts, which was determined necessary to reduce receivables to our estimate of the amount recoverable. For the three and six months ended June 30, 2017 , $9,000 of our receivables were directly written off to bad debt expense. For the three and six months ended June 30, 2016 , we did not write off any receivables to bad debt expense. For the three months ended June 30, 2017 and 2016 , $1,602,000 and $1,015,000 , respectively, of our receivables were written off against the allowance for uncollectible accounts, and for the six months ended June 30, 2017 and 2016 , $3,230,000 and $2,593,000 , respectively, of our receivables were written off against the allowance for uncollectible accounts. As of June 30, 2017 and December 31, 2016 , we did not have any allowance for uncollectible accounts for deferred rent receivables. For the three and six months ended June 30, 2017 , we did not write off any of our deferred rent receivables directly to bad debt expense. For the three and six months ended June 30, 2016 , $4,000 and $28,000 , respectively, of our deferred rent receivables were directly written off to bad debt expense. Property Acquisitions In accordance with ASC Topic 805, Business Combinations , and Accounting Standards Update, or ASU, 2017-01, Clarifying the Definition of a Business , or ASU 2017-01, we determine whether a transaction is a business combination, which requires that the assets acquired and liabilities assumed constitute a business. If the assets acquired and liabilities assumed are not a business, we account for the transaction as an asset acquisition. Under both methods, we recognize the identifiable assets acquired and liabilities assumed; however, for a transaction accounted for as an asset acquisition, we allocate the purchase price to the identifiable assets acquired and liabilities assumed based on their relative fair values. We immediately expense acquisition related expenses associated with a business combination and capitalize acquisition related expenses directly associated with an asset acquisition. As a result of our early adoption of ASU 2017-01 on January 1, 2017, we accounted for the property acquisitions we completed for the six months ended June 30, 2017 as asset acquisitions rather than business combinations. See Note 3, Real Estate Investments, Net , for a further discussion. For the six months ended June 30, 2016 , we completed nine property acquisitions, which we accounted for as business combinations. See Note 17, Business Combinations , for a further discussion. Accounts Payable and Accrued Liabilities As of June 30, 2017 and December 31, 2016 , accounts payable and accrued liabilities primarily includes insurance payable of $24,679,000 and $19,136,000 , respectively, reimbursement of payroll related costs to the managers of our senior housing — RIDEA facilities and integrated senior health campuses of $21,820,000 and $20,992,000 , respectively, accrued property taxes of $13,334,000 and $12,766,000 , respectively, accrued distributions of $9,788,000 and $10,009,000 , respectively, and accrued capital expenditures to unaffiliated parties of $5,780,000 and $5,066,000 , respectively. Recently Issued or Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , or ASU 2014-09, which replaces the existing accounting standards for revenue recognition. ASU 2014-09 provides a five-step framework to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration expected to be received in exchange for those goods or services. Since its issuance, the FASB has amended several aspects of ASU 2014-09, including provisions that address principal-versus-agent implementation guidance and identifying performance obligations. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. It may be adopted either by restating all years presented in the financial statements or by recording the impact of adoption as an adjustment to retained earnings at the beginning of the year of adoption. One source of our revenue is generated through leasing arrangements, which are excluded from ASU 2014-09 and its amendments; however, we expect that the adoption of ASU 2014-09 and its amendments on January 1, 2018 will impact our recognition of non-lease revenue, such as certain resident fees in our RIDEA structures. Additionally, upon adoption, we anticipate that we will be required to separately disclose the components of our total revenue between lease revenue accounted for under existing lease guidance and service revenue accounted for under ASU 2014-09. We have not yet selected a transition method and we expect to complete our evaluation of the impact of the adoption of ASU 2014-09 and its amendments on our consolidated financial statements during the second half of 2017. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , or ASU 2016-01, which amends the classification and measurement of financial instruments. ASU 2016-01 revises the accounting related to: (i) the classification and measurement of investments in equity securities; and (ii) the presentation of certain fair value changes for financial liabilities measured at fair value. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, with respect to only certain of the amendments in ASU 2016-01, for financial statements that have not yet been made available for issuance. ASU 2016-01 requires the application of the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with certain exceptions. We do not expect the adoption of ASU 2016-01 on January 1, 2018 to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted after December 15, 2018. We do not expect the adoption of ASU 2016-13 on January 1, 2020 to have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, or ASU 2016-15, which intends to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of ASU 2016-15 on January 1, 2018 to have a material impact on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, or ASU 2016-16, which removes the prohibition in ASC 740, Income Taxes , against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU 2016-16 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of ASU 2016-16 on January 1, 2018 to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment , or ASU 2017-04, which eliminates Step 2 from the goodwill impairment test and allows an entity to perform its goodwill impairment test by comparing the fair value of a reporting segment with its carrying amount. ASU 2017-04 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. We early adopted ASU 2017-04 on January 1, 2017, which did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, or ASU 2017-09, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Modification accounting is only applied if the value, the vesting conditions or the classification of the award (or equity or liability) changes as a result of the change in terms or conditions. ASU 2017-09 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted. We do not expect the adoption of ASU 2017-09 on January 1, 2018 to have a material impact on our consolidated financial statements.

(3) The Mezzanine Fixed Rate Notes and the Mezzanine Floating Rate Notes, or collectively, the Mezzanine Notes, evidence interests in a portion of a mezzanine loan that is secured by pledges of equity interests in the owners of a portfolio of domestic healthcare properties, which such owners are themselves owned indirectly by a non-wholly owned subsidiary of Colony NorthStar (formerly known as NorthStar Realty Finance Corp. prior to its merger with Colony Capital, Inc. and NorthStar Asset Management Group Inc. on January 10, 2017). The maturity date of the Mezzanine Floating Rate Notes may be extended by three successive one -year extension periods at the borrower’s option, subject to satisfaction of certain conditions. In October 2016, the borrower exercised its right to extend the original December 9, 2016 maturity date of the Mezzanine Floating Rate Notes for one year, to December 9, 2017. (4) Balance represents the original principal balance, decreased by any subsequent principal paydowns. The Mezzanine Floating Rate Notes and Mezzanine Fixed Rate Notes only require monthly interest payments and are subject to certain prepayment restrictions if repaid before the respective maturity dates. (5) The commercial mortgage-backed debt security, or the debt security, bears an interest rate on the stated principal amount thereof equal to 4.24% per annum, the terms of which security provide for monthly interest-only payments.

The debt security is subordinate to all other interests in FREMF 2015-KS03 Mortgage Trust and is not guaranteed by a government-sponsored entity. As of June 30, 2017 and December 31, 2016 , the net carrying amount with accretion was $66,071,000 and $64,912,000 , respectively. We classify our debt security investment as held-to-maturity and we have not recorded any unrealized holding gains or losses on such investment. We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets.

The following table lists the derivative financial instruments held by us as of June 30, 2017 and December 31, 2016 : Fair Value Instrument Notional Amount Index Interest Rate Maturity Date June 30, 2017 December 31, 2016 Cap $ 17,075,000 one month LIBOR 2.25% 02/01/18 $ — $ — Swap 140,000,000 one month LIBOR 0.82% 02/03/19 1,436,000 1,355,000 Swap 60,000,000 one month LIBOR 0.78% 02/03/19 649,000 627,000 $ 217,075,000 $ 2,085,000 $ 1,982,000 As of June 30, 2017 and December 31, 2016 , none of our derivatives were designated as hedges. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements, but do not meet the strict hedge accounting requirements of ASC Topic 815. Changes in the fair value of derivative financial instruments are recorded as a component of interest expense in gain or (loss) in fair value of derivative financial instruments in our accompanying condensed consolidated statements of operations and comprehensive income (loss). For the three months ended June 30, 2017 and 2016 , we recorded $(233,000) and $(871,000) , respectively, and for the six months ended June 30, 2017 and 2016 , we recorded $103,000 and $(1,043,000) , respectively, as an (increase) decrease to interest expense in our accompanying condensed consolidated statements of operations and comprehensive income (loss) related to the change in the fair value of our derivative financial instruments. See Note 15, Fair Value Measurements , for a further discussion of the fair value of our derivative financial instruments.

Redeemable Noncontrolling Interest [Line Items]
Redeemable Noncontrolling Interest	12. Redeemable Noncontrolling Interests On January 15, 2013, our advisor made an initial capital contribution of $2,000 to our operating partnership in exchange for 222 limited partnership units. Upon the effectiveness of the Advisory Agreement on February 26, 2014, Griffin-American Advisor became our advisor. As of June 30, 2017 and December 31, 2016 , we owned greater than a 99.99% general partnership interest in our operating partnership, and our advisor owned less than a 0.01% limited partnership interest in our operating partnership. As our advisor, Griffin-American Advisor is entitled to special redemption rights of its limited partnership units. The noncontrolling interest of our advisor in our operating partnership that has redemption features outside of our control is accounted for as a redeemable noncontrolling interest and is presented outside of permanent equity in our accompanying condensed consolidated balance sheets. See Note 14, Related Party Transactions — Liquidity Stage — Subordinated Participation Interest — Subordinated Distribution Upon Listing and Note 14, Related Party Transactions — Subordinated Distribution Upon Termination, for a further discussion of the redemption features of the limited partnership units. On December 1, 2015, we, through Trilogy REIT Holdings, LLC, or Trilogy REIT Holdings, in which we indirectly hold a 70.0% ownership interest, pursuant to an equity purchase agreement with Trilogy and other seller parties thereto, completed the acquisition of approximately 96.7% of the outstanding equity interests of Trilogy. Pursuant to the equity purchase agreement, at the closing of the acquisition, certain members of Trilogy’s pre-closing management retained a portion of the outstanding equity interests of Trilogy held by such members of Trilogy’s pre-closing management, representing in the aggregate approximately 3.3% of the outstanding equity interests of Trilogy. The noncontrolling interests held by Trilogy’s pre-closing management have redemption features outside of our control and are accounted for as redeemable noncontrolling interests in our accompanying condensed consolidated balance sheets. As of June 30, 2017 , Trilogy REIT Holdings and certain members of Trilogy’s pre-closing management owned approximately 96.7% and 3.3% of Trilogy, respectively. We record the carrying amount of redeemable noncontrolling interests at the greater of: (i) the initial carrying amount, increased or decreased for the noncontrolling interests’ share of net income or loss and distributions or (ii) the redemption value. The changes in the carrying amount of redeemable noncontrolling interests consisted of the following for the six months ended June 30, 2017 and 2016 : Six Months Ended June 30, 2017 2016 Beginning balance $ 31,507,000 $ 22,987,000 Addition 635,000 2,295,000 Reclassification from equity 390,000 — Repurchase of redeemable noncontrolling interests (20,000 ) — Distributions (384,000 ) — Fair value adjustment to redemption value 708,000 — Net loss attributable to redeemable noncontrolling interests (602,000 ) — Ending balance $ 32,234,000 $ 25,282,000

Equity [Abstract]
Equity	13. Equity Preferred Stock Our charter authorizes us to issue 200,000,000 shares of our preferred stock, par value $0.01 per share. As of June 30, 2017 and December 31, 2016 , no shares of preferred stock were issued and outstanding. Common Stock Our charter authorizes us to issue 1,000,000,000 shares of our common stock, par value $0.01 per share. On January 15, 2013, our advisor acquired 22,222 shares of our common stock for total cash consideration of $200,000 and was admitted as our initial stockholder. We used the proceeds from the sale of shares of our common stock to our advisor to make an initial capital contribution to our operating partnership. On March 12, 2015, we terminated the primary portion of our initial offering. We continued to offer shares of our common stock in our initial offering pursuant to the DRIP, until the termination of the DRIP portion of our initial offering and deregistration of our initial offering on April 22, 2015. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the SEC upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, the Amended and Restated DRIP amended the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering. See Distribution Reinvestment Plan section below for a further discussion. Through June 30, 2017 , we had issued 184,930,598 shares of our common stock in connection with the primary portion of our initial offering and 16,905,084 shares of our common stock pursuant to the DRIP and the Secondary DRIP Offering. We also repurchased 4,288,240 shares of our common stock under our share repurchase plan and granted an aggregate of 67,500 shares of our restricted common stock to our independent directors through June 30, 2017 . As of June 30, 2017 and December 31, 2016 , we had 197,637,164 and 195,780,039 shares of our common stock issued and outstanding, respectively. Accumulated Other Comprehensive Loss The changes in accumulated other comprehensive loss, net of noncontrolling interests, by component consisted of the following for the six months ended June 30, 2017 and 2016 : Six Months Ended June 30, 2017 2016 Beginning balance — foreign currency translation adjustments $ (3,029,000 ) $ (506,000 ) Net change in current period 622,000 (1,489,000 ) Ending balance — foreign currency translation adjustments $ (2,407,000 ) $ (1,995,000 ) Noncontrolling Interests As of June 30, 2017 and December 31, 2016 , Trilogy REIT Holdings owned approximately 96.7% of Trilogy. We are the indirect owner of a 70.0% interest in Trilogy REIT Holdings and serve as the sole manager of Trilogy REIT Holdings. NorthStar Healthcare Income, Inc., through certain of its subsidiaries, owns a 30.0% ownership interest in Trilogy REIT Holdings. As of June 30, 2017 and December 31, 2016 , 30.0% of the net earnings of Trilogy REIT Holdings were allocated to noncontrolling interests. In connection with the acquisition and operation of Trilogy, profit interest units in Trilogy, or the Profit Interests, were issued to Trilogy Management Services, LLC and an independent director of Trilogy, both are unaffiliated third parties that manage or direct the day-to day operations of Trilogy. The Profit Interests consist of time-based or performance-based commitments. The time-based Profit Interests were measured at their grant date fair value and vest in increments of 20.0% on each anniversary of the respective grant date over a five -year period. We amortize the time-based Profit Interests on a straight-line basis over the vesting periods, which are recorded to general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). The performance-based Profit Interests are subject to a performance commitment and vest upon liquidity events as defined in the Profit Interests agreements. The performance-based Profit Interests were measured at their grant date fair value and immediately expensed. The performance-based Profit Interests are subject to fair value measurements until vesting occurs with changes to fair value recorded to general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). For the three and six months ended June 30, 2017 we recognized stock compensation expense related to the Profit Interests of $195,000 . For the three and six months ended June 30, 2016 , we recognized stock compensation expense related to the Profit Interests of $198,000 and $393,000 , respectively. There were no canceled, expired or exercised Profit Interests during the three and six months ended June 30, 2017 and 2016 . The nonvested awards are presented as noncontrolling interests and are re-classified to redeemable noncontrolling interests upon vesting as they have redemption features outside of our control similar to the common stock units held by Trilogy’s pre-closing management once vested. See Note 12, Redeemable Noncontrolling Interests , for a further discussion. On January 6, 2016, one of our consolidated subsidiaries issued non-voting preferred shares of beneficial interests to qualified investors for total proceeds of $125,000 . These preferred shares of beneficial interests are entitled to receive cumulative preferential cash dividends at the rate of 12.5% per annum. In accordance with ASC Topic 810, we classify the value of the subsidiary’s preferred shares of beneficial interests as noncontrolling interests in our accompanying condensed consolidated balance sheets and the dividends of the preferred shares of beneficial interests as net loss attributable to noncontrolling interests in our accompanying condensed consolidated statements of operations and comprehensive income (loss). In addition, as of June 30, 2017 and December 31, 2016 , we owned an 86.0% interest in a consolidated limited liability company that owns the Lakeview IN Medical Plaza property we acquired on January 21, 2016. As such, 14.0% of the net earnings of the Lakeview IN Medical Plaza property were allocated to noncontrolling interests for the three and six months ended June 30, 2017 and 2016 . Distribution Reinvestment Plan We adopted the DRIP that allowed stockholders to purchase additional shares of our common stock through the reinvestment of distributions at an offering price equal to 95.0% of the primary offering price of our initial offering, subject to certain conditions. We had registered and reserved $35,000,000 in shares of our common stock for sale pursuant to the DRIP in our initial offering at an offering price of $9.50 per share, which we terminated on April 22, 2015. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the SEC upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, the Amended and Restated DRIP amended the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering. Pursuant to the Amended and Restated DRIP, shares are issued at a price equal to the most recently estimated value of one share of our common stock, as approved and established by our board. The Amended and Restated DRIP became effective with the distribution payment to stockholders paid in the month of November 2016, which distributions were reinvested at $9.01 per share, the estimated per share net asset value, or NAV, unanimously approved and established by our board on October 5, 2016. Formerly, shares were issued pursuant to the Secondary DRIP Offering at 95.0% of the estimated value of one share of our common stock, as estimated by our board. In all other material respects, the terms of the Secondary DRIP Offering remain unchanged by the Amended and Restated DRIP. For the three months ended June 30, 2017 and 2016 , $15,946,000 and $16,383,000 , respectively, in distributions were reinvested that resulted in 1,769,786 and 1,724,616 shares of our common stock, respectively, being issued pursuant to the Secondary DRIP Offering. For the six months ended June 30, 2017 and 2016 , $31,627,000 and $32,493,000 , respectively, in distributions were reinvested that resulted in 3,510,170 and 3,419,642 shares of our common stock, respectively, being issued pursuant to the Secondary DRIP Offering. As of June 30, 2017 and December 31, 2016 , a total of $158,300,000 and $126,673,000 , respectively, in distributions were reinvested that resulted in 16,905,084 and 13,394,914 shares of our common stock, respectively, being issued pursuant to the DRIP portion of our initial offering and the Secondary DRIP Offering. Share Repurchase Plan Our board has approved a share repurchase plan. Our share repurchase plan allows for repurchases of shares of our common stock by us when certain criteria are met. Share repurchases will be made at the sole discretion of our board. Subject to the availability of the funds for share repurchases, we will limit the number of shares of our common stock repurchased during any calendar year to 5.0% of the weighted average number of shares of our common stock outstanding during the prior calendar year; provided, however, that shares subject to a repurchase requested upon the death of a stockholder will not be subject to this cap. Funds for the repurchase of shares of our common stock will come exclusively from the cumulative proceeds we receive from the sale of shares of our common stock pursuant to the DRIP portion of our initial offering and the Secondary DRIP Offering. Furthermore, our share repurchase plan provides that if there are insufficient funds to honor all repurchase requests, pending requests will be honored among all requests for repurchase in any given repurchase period as follows: first, pro rata as to repurchases sought upon a stockholder’s death; next, pro rata as to repurchases sought by stockholders with a qualifying disability; and, finally, pro rata as to other repurchase requests. All repurchases will be subject to a one -year holding period, except for repurchases made in connection with a stockholder’s death or “qualifying disability,” as defined in our share repurchase plan. Further, all share repurchases will be repurchased following a one -year holding period at a price between 92.5% and 100% of each stockholder’s repurchase amount, depending on the period of time their shares have been held. Until October 4, 2016, the repurchase amount for shares repurchased under our share repurchase plan was equal to the lesser of the amount a stockholder paid for their shares of our common stock or the most recent per share offering price. However, if shares of our common stock were repurchased in connection with a stockholder’s death or qualifying disability, the repurchase price was no less than 100% of the price paid to acquire the shares of our common stock from us. Effective with respect to share repurchase requests submitted during the fourth quarter 2016, the Repurchase Amount, as such term is defined in our share repurchase plan, as amended, shall be equal to the lesser of (i) the amount per share that a stockholder paid for their shares of our common stock, or (ii) the most recent estimated value of one share of our common stock, as determined by our board. Accordingly, with respect to share repurchase requests submitted during or after the fourth quarter 2016, we repurchase shares as follows: (a) for stockholders who have continuously held their shares of our common stock for at least one year, the price will be 92.5% of the Repurchase Amount; (b) for stockholders who have continuously held their shares of our common stock for at least two years, the price will be 95.0% of the Repurchase Amount; (c) for stockholders who have continuously held their shares of our common stock for at least three years, the price will be 97.5% of the Repurchase Amount; (d) for stockholders who have held their shares of our common stock for at least four years, the price will be 100% of the Repurchase Amount; and (e) for requests submitted pursuant to a death or a qualifying disability, the price will be 100% of the amount per share the stockholder paid for their shares of common stock (in each case, as adjusted for any stock dividends, combinations, splits, recapitalizations and the like with respect to our common stock). On October 5, 2016, our board approved and established an estimated per share NAV of our common stock of $9.01 . For the three months ended June 30, 2017 and 2016 , we received share repurchase requests and repurchased 858,152 and 382,357 shares of our common stock, respectively, for an aggregate of $7,577,000 and $3,647,000 , respectively, at an average repurchase price of $8.83 and $9.54 per share, respectively. For the six months ended June 30, 2017 and 2016 , we received share repurchase requests and repurchased 1,660,545 and 630,840 shares of our common stock, respectively, for an aggregate of $14,705,000 and $5,999,000 , respectively, at an average repurchase price of $8.86 and $9.51 per share, respectively. As of June 30, 2017 and December 31, 2016 , we received share repurchase requests and repurchased 4,288,240 and 2,627,695 shares of our common stock, respectively, for an aggregate of $39,407,000 and $24,702,000 , respectively, at an average repurchase price of $9.19 and $9.40 per share, respectively. All shares were repurchased using proceeds we received from the sale of shares of our common stock pursuant to the DRIP portion of our initial offering and the Secondary DRIP Offering. 2013 Incentive Plan We adopted the 2013 Incentive Plan, or our incentive plan, pursuant to which our board or a committee of our independent directors may make grants of options, shares of restricted common stock, stock purchase rights, stock appreciation rights or other awards to our independent directors, employees and consultants. The maximum number of shares of our common stock that may be issued pursuant to our incentive plan is 2,000,000 shares. Through June 30, 2017 , we granted an aggregate of 37,500 shares of our restricted common stock, as defined in our incentive plan, to our independent directors in connection with their initial election or re-election to our board, of which 20.0% vested on the grant date and 20.0% will vest on each of the first four anniversaries of the grant date. In addition, through June 30, 2017 , we granted an aggregate of 30,000 shares of our restricted common stock, as defined in our incentive plan, to our independent directors in consideration for their past services rendered. These shares of restricted common stock vest under the same period described above. Shares of our restricted common stock may not be sold, transferred, exchanged, assigned, pledged, hypothecated or otherwise encumbered. Such restrictions expire upon vesting. Shares of our restricted common stock have full voting rights and rights to distributions. From the applicable dates that the required service periods began, or the service inception dates, to the applicable grant dates, we recognized compensation expense related to the shares of our restricted common stock based on the reporting date fair value, which we estimated as follows: (i) at $10.00 per share for shares of our restricted common stock granted through October 4, 2016, the then most recent price paid to acquire a share of common stock in our initial offering; or (ii) the most recent estimated per share NAV of our common stock, as determined by our board, for shares of our restricted common stock granted effective October 5, 2016. Beginning on the applicable grant dates, compensation cost related to the shares of our restricted common stock is measured based on the applicable grant date fair value, which we estimated as follows: (i) at $10.00 per share for shares of our restricted common stock granted through October 4, 2016, the then most recent price paid to acquire a share of common stock in our initial offering; or (ii) the most recent estimated value of one share of our common stock, as determined by our board, for shares of our restricted common stock granted effective October 5, 2016. On October 5, 2016, our board approved and established an estimated per share NAV of our common stock of $9.01 . Stock compensation expense is recognized from the applicable service inception dates to the applicable vesting date for each vesting tranche (i.e., on a tranche-by-tranche basis) using the accelerated attribution method. ASC Topic 718, Compensation — Stock Compensation, requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For the three and six months ended June 30, 2017 and 2016 , we did not assume any forfeitures. For the three months ended June 30, 2017 and 2016 , we recognized stock compensation expense related to the director grants of $57,000 and $38,000 , respectively, and for the six months ended June 30, 2017 and 2016 , we recognized compensation expense related to the director grants of $100,000 and $61,000 , respectively, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). As of June 30, 2017 and December 31, 2016 , there was $201,000 and $233,000 , respectively, of total unrecognized compensation expense, net of estimated forfeitures, related to nonvested shares of our restricted common stock. As of June 30, 2017 , this expense is expected to be recognized over a remaining weighted average period of 1.58 years. As of June 30, 2017 and December 31, 2016 , the weighted average grant date fair value of the nonvested shares of our restricted common stock was $394,000 and $390,000 , respectively. A summary of the status of the nonvested shares of our restricted common stock as of June 30, 2017 and December 31, 2016 , and the changes for the six months ended June 30, 2017 , is presented below: Number of Nonvested Shares of our Restricted Common Stock Weighted Average Grant Date Fair Value Balance — December 31, 2016 39,000 $ 10.00 Granted 7,500 $ 9.01 Vested (6,500 ) $ 9.77 Forfeited — $ — Balance — June 30, 2017 40,000 $ 9.85 Expected to vest — June 30, 2017 40,000 $ 9.85

We entered into the Advisory Agreement, which entitles our advisor and its affiliates to specified compensation for certain services, as well as reimbursement of certain expenses. In the aggregate, for the three months ended June 30, 2017 and 2016 , we incurred $5,622,000 and $7,806,000 , respectively, and for the six months ended June 30, 2017 and 2016 , we incurred $12,387,000 and $14,326,000 , respectively, in fees and expenses to our affiliates as detailed below. Acquisition and Development Stage Acquisition Fee We pay our advisor or its affiliates an acquisition fee of up to 2.25% of the contract purchase price, including any contingent or earn-out payments that may be paid, for each property we acquire or 2.00% of the origination or acquisition price, including any contingent or earn-out payments that may be paid, for any real estate-related investment we originate or acquire. Since January 31, 2015, the acquisition fee for property acquisitions is paid in cash equal to 2.25% of the contract purchase price. Our advisor or its affiliates are entitled to receive these acquisition fees for properties and real estate-related investments we acquire with funds raised in our initial offering including acquisitions completed after the termination of the Advisory Agreement, or funded with net proceeds from the sale of a property or real estate-related investment, subject to certain conditions. For the three months ended June 30, 2017 and 2016 , we incurred $196,000 and $3,042,000 , respectively, and for the six months ended June 30, 2017 and 2016 , we incurred $1,633,000 and $5,027,000 , respectively, in acquisition fees to our advisor. Acquisition fees in connection with the acquisition of properties accounted for as business combinations are expensed as incurred and included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Acquisition fees in connection with the acquisition of properties accounted for as asset acquisitions or the acquisition of real estate-related investments are capitalized as part of the associated investments in our accompanying condensed consolidated balance sheets. Development Fee In the event our advisor or its affiliates provide development-related services, our advisor or its affiliates receive a development fee in an amount that is usual and customary for comparable services rendered for similar projects in the geographic market where the services are provided; however, we will not pay a development fee to our advisor or its affiliates if our advisor or its affiliates elect to receive an acquisition fee based on the cost of such development. For the three and six months ended June 30, 2017 and 2016 , we did not incur any development fees to our advisor or its affiliates. Until December 31, 2016 , development fees were expensed and included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Since January 1, 2017, as a result of our early adoption of ASU 2017-01, development fees are capitalized as part of the associated asset and included in real estate investments, net in our accompanying condensed consolidated balance sheets. Reimbursement of Acquisition Expenses We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets, which are reimbursed regardless of whether an asset is acquired. The reimbursement of acquisition expenses, acquisition fees and real estate commissions paid to unaffiliated parties will not exceed, in the aggregate, 6.0% of the contract purchase price or total development costs, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors, not otherwise interested in the transaction. For the three and six months ended June 30, 2017 and 2016 , such fees and expenses did not exceed 6.0% of the contract purchase price of our acquisitions. For the three and six months ended June 30, 2017 and 2016 , we did not incur any acquisition expenses to our advisor or its affiliates. Reimbursements of acquisition expenses in connection with the acquisition of properties accounted for as business combinations are expensed as incurred and included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Reimbursements of acquisition expenses in connection with the acquisition of properties accounted for as asset acquisitions or the acquisition of real estate-related investments are capitalized as part of the associated investments in our accompanying condensed consolidated balance sheets. Operational Stage Asset Management Fee We pay our advisor or its affiliates a monthly fee for services rendered in connection with the management of our assets equal to one-twelfth of 0.75% of average invested assets, subject to our stockholders receiving distributions in an amount equal to 5.0% per annum, cumulative, non-compounded, of invested capital. For such purposes, average invested assets means the average of the aggregate book value of our assets invested in real estate properties and real estate-related investments, before deducting depreciation, amortization, bad debt and other similar non-cash reserves, computed by taking the average of such values at the end of each month during the period of calculation; and invested capital means, for a specified period, the aggregate issue price of shares of our common stock purchased by our stockholders, reduced by distributions of net sales proceeds by us to our stockholders and by any amounts paid by us to repurchase shares of our common stock pursuant to our share repurchase plan. For the three months ended June 30, 2017 and 2016 , we incurred $4,695,000 and $4,052,000 , respectively, and for the six months ended June 30, 2017 and 2016 , we incurred $9,341,000 and $7,946,000 , respectively, in asset management fees to our advisor or its affiliates. Asset management fees are included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Property Management Fee Our advisor or its affiliates may directly serve as property manager of our properties or may sub-contract their property management duties to any third party and provide oversight of such third-party property manager. We pay our advisor or its affiliates a monthly management fee equal to a percentage of the gross monthly cash receipts of such property as follows: (i) a 1.0% property management oversight fee for any stand-alone, single-tenant, net leased property; (ii) a 1.5% property management oversight fee for any property that is not a stand-alone, single-tenant, net leased property and for which our advisor or its affiliates will provide oversight of a third party that performs the duties of a property manager with respect to such property; or (iii) a fair and reasonable property management fee that is approved by a majority of our directors, including a majority of our independent directors, that is not less favorable to us than terms available from unaffiliated third parties for any property that is not a stand-alone, single-tenant, net leased property and for which our advisor or its affiliates will directly serve as the property manager without sub-contracting such duties to a third party. For the three months ended June 30, 2017 and 2016 , we incurred $575,000 and $602,000 , respectively, and for the six months ended June 30, 2017 and 2016 , we incurred $1,172,000 and $1,235,000 , respectively, in property management fees to our advisor or its affiliates. Property management fees are included in property operating expenses and rental expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Lease Fees We pay our advisor or its affiliates a separate fee for any leasing activities in an amount not to exceed the fee customarily charged in arm’s-length transactions by others rendering similar services in the same geographic area for similar properties as determined by a survey of brokers and agents in such area. Such fee is generally expected to range from 3.0% to 6.0% of the gross revenues generated during the initial term of the lease. For the three months ended June 30, 2017 and 2016 , we incurred $93,000 and $95,000 , respectively, and for the six months ended June 30, 2017 and 2016 , we incurred $120,000 and $95,000 , respectively, in lease fees to our advisor or its affiliates. Lease fees are capitalized as lease commissions and included in other assets, net in our accompanying condensed consolidated balance sheets. Construction Management Fee In the event that our advisor or its affiliates assist with planning and coordinating the construction of any capital or tenant improvements, our advisor or its affiliates are paid a construction management fee of up to 5.0% of the cost of such improvements. For the three months ended June 30, 2017 and 2016 , we incurred $14,000 and $0 , respectively, and for the six months ended June 30, 2017 and 2016 , we incurred $18,000 and $1,000 , respectively, in construction management fees to our advisor or its affiliates. Construction management fees are capitalized as part of the associated asset and included in real estate investments, net in our accompanying condensed consolidated balance sheets or are expensed and included in our accompanying condensed consolidated statements of operations and comprehensive income (loss), as applicable. Operating Expenses We reimburse our advisor or its affiliates for operating expenses incurred in rendering services to us, subject to certain limitations. However, we cannot reimburse our advisor or its affiliates at the end of any fiscal quarter for total operating expenses that, in the four consecutive fiscal quarters then ended, exceed the greater of: (i) 2.0% of our average invested assets, as defined in the Advisory Agreement; or (ii) 25.0% of our net income, as defined in the Advisory Agreement, unless our independent directors determined that such excess expenses were justified based on unusual and nonrecurring factors which they deem sufficient. Our operating expenses as a percentage of average invested assets and as a percentage of net income were 0.9% and 16.0% , respectively, for the 12 months ended June 30, 2017 ; therefore, our operating expenses did not exceed the aforementioned limitation. For the three months ended June 30, 2017 and 2016 , our advisor or its affiliates incurred operating expenses on our behalf of $49,000 and $15,000 , respectively, and for the six months ended June 30, 2017 and 2016 , our advisor or its affiliates incurred operating expenses on our behalf of $103,000 and $22,000 , respectively. Operating expenses are generally included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Compensation for Additional Services We pay our advisor and its affiliates for services performed for us other than those required to be rendered by our advisor or its affiliates under the Advisory Agreement. The rate of compensation for these services has to be approved by a majority of our board, including a majority of our independent directors, and cannot exceed an amount that would be paid to unaffiliated parties for similar services. For the three and six months ended June 30, 2017 and 2016 , our advisor and its affiliates were not compensated for any additional services. Liquidity Stage Disposition Fees For services relating to the sale of one or more properties, we pay our advisor or its affiliates a disposition fee of up to the lesser of 2.0% of the contract sales price or 50.0% of a customary competitive real estate commission given the circumstances surrounding the sale, in each case as determined by our board, including a majority of our independent directors, upon the provision of a substantial amount of the services in the sales effort. The amount of disposition fees paid, when added to the real estate commissions paid to unaffiliated parties, will not exceed the lesser of the customary competitive real estate commission or an amount equal to 6.0% of the contract sales price. For the three and six months ended June 30, 2017 , our advisor agreed to waive the disposition fees that may otherwise have been due to our advisor pursuant to the Advisory Agreement. See Note 3, Real Estate Investments, Net — Dispositions in 2017, for a further discussion. For the three and six months ended June 30, 2016 , we did not incur any disposition fees to our advisor or its affiliates. Subordinated Participation Interest Subordinated Distribution of Net Sales Proceeds In the event of liquidation, we will pay our advisor a subordinated distribution of net sales proceeds. The distribution will be equal to 15.0% of the remaining net proceeds from the sales of properties, after distributions to our stockholders, in the aggregate, of: (i) a full return of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan); plus (ii) an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock, as adjusted for distributions of net sales proceeds. Actual amounts to be received depend on the sale prices of properties upon liquidation. For the three and six months ended June 30, 2017 and 2016 , we did not incur any such distributions to our advisor. Subordinated Distribution Upon Listing Upon the listing of shares of our common stock on a national securities exchange, in redemption of our advisor’s limited partnership units, we will pay our advisor a distribution equal to 15.0% of the amount by which: (i) the market value of our outstanding common stock at listing plus distributions paid prior to listing exceeds (ii) the sum of the total amount of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan) and the amount of cash that, if distributed to stockholders as of the date of listing, would have provided them an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock through the date of listing. Actual amounts to be paid depend upon the market value of our outstanding stock at the time of listing, among other factors. For the three and six months ended June 30, 2017 and 2016 , we did not incur any such distributions to our advisor. Subordinated Distribution Upon Termination Pursuant to the Agreement of Limited Partnership, as amended, of our operating partnership, upon termination or non-renewal of the Advisory Agreement, our advisor will also be entitled to a subordinated distribution in redemption of its limited partnership units from our operating partnership equal to 15.0% of the amount, if any, by which: (i) the appraised value of our assets on the termination date, less any indebtedness secured by such assets, plus total distributions paid through the termination date, exceeds (ii) the sum of the total amount of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan) and the total amount of cash equal to an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock through the termination date. In addition, our advisor may elect to defer its right to receive a subordinated distribution upon termination until either a listing or other liquidity event, including a liquidation, sale of substantially all of our assets or merger in which our stockholders receive in exchange for their shares of our common stock, shares of a company that are traded on a national securities exchange. As of June 30, 2017 and 2016 , we had not recorded any charges to earnings related to the subordinated distribution upon termination. Accounts Payable Due to Affiliates The following amounts were outstanding to our affiliates as of June 30, 2017 and December 31, 2016 : Fee June 30, 2017 December 31, 2016 Asset and property management fees $ 1,752,000 $ 1,736,000 Acquisition fees 205,000 202,000 Development fees — 105,000 Lease commissions 78,000 89,000 Construction management fees 13,000 38,000 Operating expenses 2,000 16,000 $ 2,050,000 $ 2,186,000

Fair Value Measurements	15. Fair Value Measurements Assets and Liabilities Reported at Fair Value The table below presents our assets and liabilities measured at fair value on a recurring basis as of June 30, 2017 , aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Derivative financial instruments $ — $ 2,085,000 $ — $ 2,085,000 Contingent consideration receivable — — — — Total assets at fair value $ — $ 2,085,000 $ — $ 2,085,000 Liabilities: Contingent consideration obligations $ — $ — $ 9,137,000 $ 9,137,000 Warrants — — 1,105,000 1,105,000 Total liabilities at fair value $ — $ — $ 10,242,000 $ 10,242,000 The table below presents our assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 , aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Derivative financial instruments $ — $ 1,982,000 $ — $ 1,982,000 Contingent consideration receivable — — — — Total assets at fair value $ — $ 1,982,000 $ — $ 1,982,000 Liabilities: Contingent consideration obligations $ — $ — $ 8,992,000 $ 8,992,000 Warrants — — 1,250,000 1,250,000 Total liabilities at fair value $ — $ — $ 10,242,000 $ 10,242,000 There were no transfers into or out of fair value measurement levels during the six months ended June 30, 2017 and 2016 . Derivative Financial Instruments We use interest rate swaps and interest rate caps to manage interest rate risk associated with floating-rate debt. The valuation of these instruments is determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, as well as option volatility. The fair values of interest rate swaps are determined by netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates derived from observable market interest rate curves. To comply with the provisions of ASC Topic 820, Fair Value Measurements and Disclosures , or ASC Topic 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Although we have determined that the majority of the inputs used to value our derivative financial instruments fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with these instruments utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and our counterparty. However, as of June 30, 2017 , we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Contingent Consideration Asset As of June 30, 2017 , we have not recorded any contingent consideration receivables. In connection with our acquisition of Mt. Juliet TN MOB in March 2015, there is a contingent consideration receivable in the range of $0 up to a maximum of $190,000 . We would receive payment of contingent consideration in the event that a tenant occupying 6,611 square feet of GLA terminates their lease prior to March 31, 2018, and to the extent there is a shortfall in rent from any replacement tenant. As of June 30, 2017 , we do not believe that we will receive such amount and therefore we have not recorded any contingent consideration receivable. When recorded by us, contingent consideration receivables will be included in other assets, net in our accompanying condensed consolidated balance sheets. Liabilities As of June 30, 2017 and December 31, 2016 , we have accrued $9,137,000 and $8,992,000 , respectively, as contingent consideration obligations in connection with our property acquisitions, which is included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets. Such consideration will be paid upon various conditions being met, including our tenants achieving certain operating performance metrics and sellers’ leasing unoccupied space, as discussed below. Of the amount accrued as of June 30, 2017 , $9,059,000 relates to our acquisition of North Carolina ALF Portfolio in January and June 2015, $50,000 relates to our acquisition of King of Prussia PA MOB in January 2015 and $28,000 relates to the additional building we acquired and added to our existing North Carolina ALF Portfolio in January 2017 . Of the amount accrued as of December 31, 2016 , $8,942,000 relates to our acquisition of North Carolina ALF Portfolio in January and June 2015 and $50,000 relates to our acquisition of King of Prussia PA MOB. The estimated total amount of $9,059,000 related to our acquisition of North Carolina ALF Portfolio in January and June 2015 will be paid based upon the computation in the lease agreement and receipt of notification within three years after the applicable acquisition date that the tenant has increased its earnings before interest, taxes, depreciation and rent cost, or EBITDAR, as defined in the lease agreement, for the preceding three months. There is no minimum required payment but the total maximum is capped at $35,144,000 and is also limited by the tenant’s ability to increase its EBITDAR. Any payment made will result in an increase in the monthly rent charged to the tenant and additional rental revenue to us. Upon the tenant meeting certain conditions under the lease agreement and providing us notice in October 2016, we paid $10,000,000 towards this obligation related to the Wake Forest Facility in November 2016. We have assumed that the tenant will meet the remaining conditions under the lease agreement and that we will pay the remaining contingent consideration for the three other facilities three years from the date of the applicable acquisition. Warrants As of June 30, 2017 and December 31, 2016 , we have recorded $1,105,000 and $1,250,000 , respectively, related to warrants in Trilogy common units held by certain members of Trilogy’s pre-closing management, which is included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets. Once exercised, these warrants have redemption features similar to the common units held by members of Trilogy’s pre-closing management. See Note 12, Redeemable Noncontrolling Interests , for a further discussion. As of June 30, 2017 and December 31, 2016 , the carrying value is a reasonable estimate of fair value. Unobservable Inputs and Reconciliation The fair value of the contingent consideration is determined based on the facts and circumstances existing at each reporting date and the likelihood of the counterparty achieving the necessary conditions based on a probability weighted discounted cash flow analysis based, in part, on significant inputs which are not observable in the market. As a result, we have determined that our contingent consideration valuations are classified in Level 3 of the fair value hierarchy. Any changes in the fair value of our contingent consideration assets and liabilities subsequent to their acquisition date valuations are charged to earnings. Gains and losses recognized on contingent consideration assets and liabilities are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). The following table shows quantitative information about unobservable inputs related to Level 3 fair value measurements used as of June 30, 2017 and December 31, 2016 for the contingent consideration obligations: Range of Inputs or Inputs Acquisition Unobservable Inputs(1) June 30, 2017 December 31, 2016 North Carolina ALF Portfolio — North Raleigh and Mooresville(2) Tenant’s Annualized EBITDAR, as defined, for the Three Months Prior to Payment $ 3,476,000 $ 3,459,000 Timing of Payment January 27, 2018 January 27, 2018 Applicable Rate, as defined in the lease agreement 7.20% 7.20% Discount Rate per Annum 1.38% 1.20% Percentage of Eligible Payment Requested 100% 100% North Carolina ALF Portfolio — Clemmons(2) Tenant’s Annualized EBITDAR, as defined, for the Three Months Prior to Payment $ 1,742,000 $ 1,753,000 Timing of Payment June 28, 2018 June 28, 2018 Applicable Rate, as defined in the lease agreement 7.20% 7.20% Discount Rate per Annum 1.38% 1.20% Percentage of Eligible Payment Requested 100% 100% King of Prussia PA MOB(3) Percentage of Allowance for Leasing Commissions to be Paid 100% 100% North Carolina ALF Portfolio — Huntersville(2) Tenant’s Annualized EBITDAR, as defined, for the Three Months Prior to Payment $ 1,244,000 N/A Timing of Payment January 17, 2020 N/A Applicable Rate, as defined in the lease agreement 7.20% N/A Discount Rate per Annum 1.38% N/A Percentage of Eligible Payment Requested 100% N/A ___________ (1) Significant increases or decreases in any of the unobservable inputs in isolation or in the aggregate would result in a significantly higher or lower fair value measurement to the contingent consideration obligation as of June 30, 2017 and December 31, 2016 . (2) The most significant input to the valuation is the tenant’s annualized EBITDAR, as defined in the lease agreement. An increase (decrease) in the tenant’s annualized EBITDAR would increase (decrease) the fair value. (3) An increase (decrease) in the leasing commissions to be paid would increase (decrease) the fair value. The following is a reconciliation of the beginning and ending balances of our contingent consideration asset and liabilities for the three and six months ended June 30, 2017 and 2016 : Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Contingent Consideration Receivable: Beginning balance $ — $ — $ — $ — Additions to contingent consideration receivable — — — — Realized/unrealized (gains) losses recognized in earnings — — — — Ending balance $ — $ — $ — $ — Amount of total (gains) losses included in earnings attributable to the change in unrealized (gains) losses related to asset still held $ — $ — $ — $ — Contingent Consideration Obligations: Beginning balance $ 8,993,000 $ 5,196,000 $ 8,992,000 $ 5,912,000 Addition to contingent consideration obligations 28,000 — 28,000 — Realized/unrealized losses recognized in earnings 116,000 624,000 117,000 258,000 Settlement of obligations — — — (350,000 ) Ending balance $ 9,137,000 $ 5,820,000 $ 9,137,000 $ 5,820,000 Amount of total losses included in earnings attributable to the change in unrealized losses related to obligations still held $ 116,000 $ 624,000 $ 117,000 $ 258,000 Financial Instruments Disclosed at Fair Value ASC Topic 825, Financial Instruments, requires disclosure of the fair value of financial instruments, whether or not recognized on the face of the balance sheet. Fair value is defined under ASC Topic 820. Our accompanying condensed consolidated balance sheets include the following financial instruments: real estate notes receivable, debt security investment, cash and cash equivalents, accounts and other receivables, restricted cash, real estate deposits, accounts payable and accrued liabilities, accounts payable due to affiliates, mortgage loans payable and borrowings under our lines of credit and term loan. We consider the carrying values of cash and cash equivalents, accounts and other receivables, restricted cash, real estate deposits and accounts payable and accrued liabilities to approximate the fair value for these financial instruments based upon an evaluation of the underlying characteristics, market data and because of the short period of time between origination of the instruments and their expected realization. The fair value of cash and cash equivalents is classified in Level 1 of the fair value hierarchy. The fair value of accounts payable due to affiliates is not determinable due to the related party nature of the accounts payable. The fair values of the other financial instruments are classified in Level 2 of the fair value hierarchy. The fair value of our real estate notes receivable and debt security investment are estimated using a discounted cash flow analysis using interest rates available to us for investments with similar terms and maturities. The fair value of the mortgage loans payable and our lines of credit and term loan are estimated using a discounted cash flow analysis using borrowing rates available to us for debt instruments with similar terms and maturities. We have determined that the valuations of our real estate notes receivable, debt security investment, mortgage loans payable and lines of credit and term loan are classified in Level 2 within the fair value hierarchy. The carrying amounts and estimated fair values of such financial instruments as of June 30, 2017 and December 31, 2016 were as follows: June 30, 2017 December 31, 2016 Carrying Amount Fair Value Carrying Amount Fair Value Financial Assets: Real estate notes receivable $ 34,757,000 $ 35,623,000 $ 36,205,000 $ 37,231,000 Debt security investment $ 66,071,000 $ 93,412,000 $ 64,912,000 $ 94,320,000 Financial Liabilities: Mortgage loans payable $ 617,581,000 $ 581,198,000 $ 495,717,000 $ 495,532,000 Lines of credit and term loan $ 583,875,000 $ 590,366,000 $ 639,693,000 $ 647,336,000

Income Tax Disclosure [Abstract]
Income Taxes	16. Income Taxes As a REIT, we generally will not be subject to federal income tax on taxable income that we distribute to our stockholders. We have elected to treat certain of our consolidated subsidiaries as taxable REIT subsidiaries, or TRSs, pursuant to the Code. TRSs may participate in services that would otherwise be considered impermissible for REITs and are subject to federal and state income tax at regular corporate tax rates. The components of income (loss) before taxes for the three and six months ended June 30, 2017 and 2016 were as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Domestic $ 1,069,000 $ (52,678,000 ) $ (6,193,000 ) $ (98,654,000 ) Foreign (111,000 ) (115,000 ) (589,000 ) (142,000 ) Income (loss) before income taxes $ 958,000 $ (52,793,000 ) $ (6,782,000 ) $ (98,796,000 ) The components of income tax (benefit) expense for the three and six months ended June 30, 2017 and 2016 were as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Federal deferred $ (1,139,000 ) $ (4,649,000 ) $ (3,482,000 ) $ (8,394,000 ) State deferred (116,000 ) (431,000 ) (349,000 ) (856,000 ) Foreign deferred 2,000 (87,000 ) (61,000 ) (87,000 ) Federal current — (1,070,000 ) — 8,000 Foreign current 85,000 186,000 149,000 167,000 Valuation allowances 603,000 5,167,000 2,965,000 9,337,000 Total income tax (benefit) expense $ (565,000 ) $ (884,000 ) $ (778,000 ) $ 175,000 Current Income Tax Federal and state income taxes are generally a function of the level of income recognized by our TRSs. Foreign income taxes are generally a function of our income on our real estate and real estate-related investments located in the United Kingdom, or UK, and Isle of Man. Deferred Taxes Deferred income tax is generally a function of the period’s temporary differences (primarily basis differences between tax and financial reporting for real estate assets and equity investments) and generation of tax net operating losses that may be realized in future periods depending on sufficient taxable income. We apply the rules under ASC 740-10, Accounting for Uncertainty in Income Taxes, for uncertain tax positions using a “more likely than not” recognition threshold for tax positions. Pursuant to these rules, we will initially recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits of the tax position, that such a position will be sustained upon examination by the relevant tax authorities. If the tax benefit meets the “more likely than not” threshold, the measurement of the tax benefit will be based on our estimate of the ultimate tax benefit to be sustained if audited by the taxing authority. As of June 30, 2017 and December 31, 2016 , we did not have any tax benefits or liabilities for uncertain tax positions that we believe should be recognized in our accompanying condensed consolidated financial statements. We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A valuation allowance is established if we believe it is more likely than not that all or a portion of the deferred tax assets are not realizable. As of June 30, 2017 and December 31, 2016 , our valuation allowance substantially reserves the net deferred tax assets due to inherent uncertainty of future income. We will continue to monitor industry and economic conditions, and our ability to generate taxable income based on our business plan and available tax planning strategies, which would allow us to utilize the tax benefits of the net deferred tax assets and thereby allow us to reverse all, or a portion of, our valuation allowance in the future.

Business Combinations [Abstract]
Business Combinations	17. Business Combinations For the six months ended June 30, 2017 , none of our property acquisitions were accounted for as business combinations. See Note 3, Real Estate Investments, Net , for a discussion of our 2017 property acquisitions accounted for as asset acquisitions. For the six months ended June 30, 2016 , using cash on hand and debt financing, we completed nine property acquisitions comprising 11 buildings, which have been accounted for as business combinations. The aggregate contract purchase price for these property acquisitions was $268,224,000 , plus closing costs and acquisition fees of $7,008,000 , which are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Results of operations for the property acquisitions during the six months ended June 30, 2016 are reflected in our accompanying condensed consolidated statements of operations and comprehensive income (loss) for the period from the date of acquisition of each property through June 30, 2016 . For the period from the acquisition date through June 30, 2016 , we recognized the following amounts of revenue and net loss for the property acquisitions: Acquisition Revenue Net Loss 2016 Acquisitions $ 5,803,000 $ (642,000 ) The following table summarizes the acquisition date fair values of the assets acquired and liabilities assumed of our nine property acquisitions for the six months ended June 30, 2016 : 2016 Acquisitions Building and improvements $ 221,661,000 Land 14,693,000 Furniture, fixtures and equipment 644,000 In-place leases 20,584,000 Above-market leases 1,324,000 Certificates of need 10,101,000 Total assets acquired 269,007,000 Below-market leases (1,423,000 ) Total liabilities assumed (1,423,000 ) Net assets acquired $ 267,584,000 Assuming the property acquisitions in 2016 discussed above had occurred on January 1, 2015, for the three and six months ended June 30, 2016 and 2015, unaudited pro forma revenue, net loss, net loss attributable to controlling interest and net loss per common share attributable to controlling interest — basic and diluted would have been as follows: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Revenue $ 242,171,000 $ 21,578,000 $ 493,160,000 $ 39,749,000 Net loss $ (45,254,000 ) $ (16,608,000 ) $ (85,648,000 ) $ (31,594,000 ) Net loss attributable to controlling interest $ (32,928,000 ) $ (15,873,000 ) $ (60,642,000 ) $ (30,153,000 ) Net loss per com mon share attributable to controlling interest — basic and diluted $ (0.17 ) $ (0.08 ) $ (0.31 ) $ (0.17 ) The unaudited pro forma adjustments assume that the offering proceeds, at a price of $10.00 per share, net of offering costs, were raised as of January 1, 2015. In addition, acquisition related expenses associated with the acquisitions have been excluded from the pro forma results in 2016 and added to the 2015 pro forma results. The pro forma results are not necessarily indicative of the operating results that would have been obtained had the acquisitions occurred at the beginning of the periods presented, nor are they necessarily indicative of future operating results.

Segment Reporting [Abstract]
Segment Reporting Disclosure	18. Segment Reporting ASC Topic 280, Segment Reporting , establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. We segregate our operations into reporting segments in order to assess the performance of our business in the same way that management reviews our performance and makes operating decisions. Accordingly, when we acquired our first medical office building in June 2014; senior housing facility in September 2014; hospital in December 2014; senior housing — RIDEA portfolio in May 2015; skilled nursing facilities in October 2015; and integrated senior health campuses in December 2015, we added a new reportable business segment at such time. As of June 30, 2017 , we evaluated our business and made resource allocations based on six reportable business segments: medical office buildings, hospitals, skilled nursing facilities, senior housing, senior housing — RIDEA and integrated senior health campuses. Our medical office buildings are typically leased to multiple tenants under separate leases in each building, thus requiring active management and responsibility for many of the associated operating expenses (although many of these are, or can effectively be, passed through to the tenants). In addition, our medical office buildings segment includes the Mezzanine Notes. Our hospital investments are primarily single-tenant properties that lease the facilities to unaffiliated tenants under triple-net and generally master leases that transfer the obligation for all facility operating costs (including maintenance, repairs, taxes, insurance and capital expenditures) to the tenant. Our skilled nursing facilities and senior housing facilities are similarly structured as our hospital investments. In addition, our senior housing segment includes our debt security investment and Crown Senior Care Facility, a facility agreement we entered into with Caring Homes (TFP) Group Limited, or the CHG Borrower, an unaffiliated third party, on September 16, 2015, which was collateralized by three senior housing facilities in the UK and the income from the CHG Borrower’s operations and which was settled in full on November 15, 2016. Our senior housing — RIDEA properties include senior housing facilities that are owned and operated utilizing a RIDEA structure. Our integrated senior health campuses include a range of assisted living, memory care, independent living, skilled nursing services and certain ancillary businesses. We evaluate performance based upon segment net operating income. We define segment net operating income as total revenues, less property operating expenses and rental expenses, which excludes depreciation and amortization, general and administrative expenses, acquisition related expenses, interest expense, gain (loss) on dispositions of real estate investments, impairment of real estate investments, foreign currency gain (loss), other income, loss from unconsolidated entities and income tax benefit (expense) for each segment. We believe that net income (loss), as defined by GAAP, is the most appropriate earnings measurement. However, we believe that segment net operating income serves as an appropriate supplemental performance measure to net income (loss) because it allows investors and our management to measure unlevered property-level operating results and to compare our operating results to the operating results of other real estate companies and between periods on a consistent basis. Interest expense, depreciation and amortization and other expenses not attributable to individual properties are not allocated to individual segments for purposes of assessing segment performance. Non-segment assets primarily consist of corporate assets including cash and cash equivalents, other receivables, real estate deposits, deferred financing costs, interest rate swap assets and other assets not attributable to individual properties. Summary information for the reportable segments during the three and six months ended June 30, 2017 and 2016 was as follows: Medical Office Buildings Skilled Nursing Facilities Hospitals Senior

Concentration of Credit Risk

Concentration of Credit Risk	6 Months Ended

Concentration of Credit Risk [Abstract]
Concentration of Credit Risk	19. Concentration of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk are primarily real estate notes receivable and debt security investment, cash and cash equivalents, accounts and other receivables, restricted cash and real estate deposits. We are exposed to credit risk with respect to the real estate notes receivable and debt security investment, but we believe collection of the outstanding amount is probable. We believe that the risk is further mitigated as the real estate notes receivable are secured by property and there is a guarantee of completion agreement executed between the parent company of the borrowers and us. Cash and cash equivalents are generally invested in investment-grade, short-term instruments with a maturity of three months or less when purchased. We have cash and cash equivalents in financial institutions that are insured by the Federal Deposit Insurance Corporation, or FDIC. As of June 30, 2017 and December 31, 2016 , we had cash and cash equivalents in excess of FDIC insured limits. We believe this risk is not significant. Concentration of credit risk with respect to accounts receivable from tenants is limited. We perform credit evaluations of prospective tenants and security deposits are obtained at the time of property acquisition and upon lease execution. Based on leases in effect as of June 30, 2017 , properties in one state in the United States accounted for 10.0% or more of the annualized base rent or annualized net operating income of our total property portfolio. Properties located in Indiana accounted for 34.9% of the annualized base rent or annualized net operating income of our total property portfolio. Accordingly, there is a geographic concentration of risk subject to fluctuations in such state’s economy. Based on leases in effect as of June 30, 2017 , our six reportable business segments, integrated senior health campuses, medical office buildings, senior housing — RIDEA, senior housing, skilled nursing facilities and hospitals accounted for 43.4% , 30.0% , 10.3% , 6.3% , 5.9% and 4.1% , respectively, of our annualized base rent or annualized net operating income. As of June 30, 2017 , none of our tenants at our properties accounted for 10.0% or more of our aggregate annualized base rent or annualized net operating income, which is based on contractual base rent from leases in effect inclusive of our senior housing — RIDEA facilities and integrated senior health campuses operations as of June 30, 2017 .

Earnings Per Share [Abstract]
Per Share Data	20. Per Share Data We report earnings (loss) per share pursuant to ASC Topic 260, Earnings per Share . Basic earnings (loss) per share for all periods presented are computed by dividing net income (loss) applicable to common stock by the weighted average number of shares of our common stock outstanding during the period. Net income (loss) applicable to common stock is calculated as net income (loss) attributable to controlling interest less distributions allocated to participating securities of $6,000 and $3,000 , respectively, for the three months ended June 30, 2017 and 2016 , and $12,000 and $6,000 , respectively, for the six months ended June 30, 2017 and 2016 . Diluted earnings (loss) per share are computed based on the weighted average number of shares of our common stock and all potentially dilutive securities, if any. Nonvested shares of our restricted common stock and redeemable limited partnership units of our operating partnership are participating securities and give rise to potentially dilutive shares of our common stock. As of June 30, 2017 and 2016 , there were 40,000 and 23,500 nonvested shares, respectively, of our restricted common stock outstanding, but such shares were excluded from the computation of diluted earnings per share because such shares were anti-dilutive during these periods. As of June 30, 2017 and 2016 , there were 222 units of redeemable limited partnership units of our operating partnership outstanding, but such units were also excluded from the computation of diluted earnings (loss) per share because such units were anti-dilutive during these periods.

Subsequent Events [Abstract]
Subsequent Events	21. Subsequent Events Acquisition of Real Estate Investment On July 17, 2017, we, through a majority-owned subsidiary of Trilogy, of which we own 67.7% , acquired land in Indiana for a contract purchase price of $250,000 , plus an acquisition fee paid in cash to our advisor of approximately $4,000 and closing costs. The acquisition of land was financed using cash on hand. Disposition of Real Estate Investment On July 20, 2017, we disposed of one integrated senior health campus in Fremont, Ohio for a contract sales price of $400,000 . Our advisor agreed to waive the disposition fee and expense reimbursements for such disposition that may otherwise have been due to our advisor pursuant to the Advisory Agreement. Our advisor did not receive any additional securities, shares of our stock or any other form of consideration or any repayment as a result of the waiver of such disposition fee and expense reimbursements. Amendment to 2016 Corporate Line of Credit On August 3, 2017, we entered into a First Amendment, Waiver and Commitment Increase Agreement, or the Amendment, with our operating partnership, Bank of America, KeyBank, and the lenders named therein, to amend the 2016 Corporate Credit Agreement. The material terms of the Amendment provide for: (i) an increase in the 2016 Corporate Term Loan Facility in an amount equal to $50,000,000 ; (ii) the establishment of an additional capitalization rate of 8.75% for any Real Property Asset, as defined in the 2016 Corporate Credit Agreement, with mixed uses consisting of both assisted living and independent living properties and skilled nursing facilities, but specifically excluding medical office buildings and life science buildings; (iii) a revision to the definition of Term Loan Commitment, as defined in the 2016 Corporate Credit Agreement, to reflect the increase in the Term Loan Facility and specify that the aggregate principal amount of the Term Loan Commitments of all of the Term Loan Lenders, as defined in the 2016 Corporate Credit Agreement, as in effect on the effective date of the Amendment is $250,000,000 ; (iv) an agreement by each Term Loan Lender severally, but not jointly, to fund its pro rata share of the Initial Term Loan, as defined in the Amendment, and Incremental Term Loan, as defined in the Amendment, subject to the terms and conditions set forth in the Amendment; (v) the obligation of the Credit Parties, as defined in the 2016 Corporate Credit Agreement, to cause the Consolidated Secured Leverage Ratio, as defined in the 2016 Corporate Credit Agreement, as of the end of any fiscal quarter, to be equal to or less than 40% ; (vi) the Lenders’ waiver of the notice requirement regarding the change in name and form of organization of certain subsidiary guarantors, as set forth in the Amendment; and (vii) the addition of Bank of the West, or New Lender, as a party to the 2016 Corporate Credit Agreement and a Term Loan Lender and Lender, as defined in the 2016 Corporate Credit Agreement, and New Lender’s agreement to be bound by all terms, provisions and conditions applicable to Lenders contained in the 2016 Corporate Credit Agreement. As a result of the Amendment, as of August 3, 2017, our aggregate borrowing capacity under the 2016 Corporate Line of Credit was $550,000,000 . As of August 3, 2017, there was $466,000,000 in aggregate borrowings outstanding under the 2016 Corporate Line of Credit and $84,000,000 remained available.

Accounting Policies [Abstract]
Basis of Presentation	Because we are the sole general partner of our operating partnership and have unilateral control over its management and major operating decisions (even if additional limited partners are admitted to our operating partnership), the accounts of our operating partnership are consolidated in our accompanying condensed consolidated financial statements. All intercompany accounts and transactions are eliminated in consolidation. Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries in which we have control, as well as any variable interest entities, or VIEs, in which we are the primary beneficiary. We evaluate our ability to control an entity, and whether the entity is a VIE and we are the primary beneficiary, by considering substantive terms of the arrangement and identifying which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance as defined in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation , or ASC Topic 810. We operate and intend to co ntinue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries of which we have control, will own substantially all of the interests in properties acquired on our behalf.
Interim Unaudited Financial Data	Interim Unaudited Financial Data Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments which are, in our view, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such full year results may be less favorable. In preparing our accompanying condensed consolidated financial statements, management has evaluated subsequent events through the financial statement issuance date. We believe that although the disclosures contained herein are adequate to prevent the information presented from being misleading, our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2016 Annual Report on Form 10-K, as filed with the SEC on March 15, 2017.
Use of Estimates	Use of Estimates The preparation of our accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions.
Allowance for Uncollectible Accounts	Allowance for Uncollectible Accounts Tenant and resident receivables and unbilled deferred rent receivables are carried net of an allowance for uncollectible amounts. An allowance is maintained for estimated losses resulting from the inability of certain tenants or residents to meet the contractual obligations under their lease agreements. We also maintain an allowance for deferred rent receivables arising from the straight-line recognition of rents. Such allowances are charged to bad debt expense, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s or resident’s financial condition, security deposits, letters of credit, lease guarantees, current economic conditions and other relevant factors.
Business Combinations Policy	Property Acquisitions In accordance with ASC Topic 805, Business Combinations , and Accounting Standards Update, or ASU, 2017-01, Clarifying the Definition of a Business , or ASU 2017-01, we determine whether a transaction is a business combination, which requires that the assets acquired and liabilities assumed constitute a business. If the assets acquired and liabilities assumed are not a business, we account for the transaction as an asset acquisition. Under both methods, we recognize the identifiable assets acquired and liabilities assumed; however, for a transaction accounted for as an asset acquisition, we allocate the purchase price to the identifiable assets acquired and liabilities assumed based on their relative fair values. We immediately expense acquisition related expenses associated with a business combination and capitalize acquisition related expenses directly associated with an asset acquisition.
Accounts Payable and Accrued Liabilities	Accounts Payable and Accrued Liabilities As of June 30, 2017 and December 31, 2016 , accounts payable and accrued liabilities primarily includes insurance payable of $24,679,000 and $19,136,000 , respectively, reimbursement of payroll related costs to the managers of our senior housing — RIDEA facilities and integrated senior health campuses of $21,820,000 and $20,992,000 , respectively, accrued property taxes of $13,334,000 and $12,766,000 , respectively, accrued distributions of $9,788,000 and $10,009,000 , respectively, and accrued capital expenditures to unaffiliated parties of $5,780,000 and $5,066,000 , respectively.
Recently Issued Accounting Pronouncements	Recently Issued or Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , or ASU 2014-09, which replaces the existing accounting standards for revenue recognition. ASU 2014-09 provides a five-step framework to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration expected to be received in exchange for those goods or services. Since its issuance, the FASB has amended several aspects of ASU 2014-09, including provisions that address principal-versus-agent implementation guidance and identifying performance obligations. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. It may be adopted either by restating all years presented in the financial statements or by recording the impact of adoption as an adjustment to retained earnings at the beginning of the year of adoption. One source of our revenue is generated through leasing arrangements, which are excluded from ASU 2014-09 and its amendments; however, we expect that the adoption of ASU 2014-09 and its amendments on January 1, 2018 will impact our recognition of non-lease revenue, such as certain resident fees in our RIDEA structures. Additionally, upon adoption, we anticipate that we will be required to separately disclose the components of our total revenue between lease revenue accounted for under existing lease guidance and service revenue accounted for under ASU 2014-09. We have not yet selected a transition method and we expect to complete our evaluation of the impact of the adoption of ASU 2014-09 and its amendments on our consolidated financial statements during the second half of 2017. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , or ASU 2016-01, which amends the classification and measurement of financial instruments. ASU 2016-01 revises the accounting related to: (i) the classification and measurement of investments in equity securities; and (ii) the presentation of certain fair value changes for financial liabilities measured at fair value. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, with respect to only certain of the amendments in ASU 2016-01, for financial statements that have not yet been made available for issuance. ASU 2016-01 requires the application of the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with certain exceptions. We do not expect the adoption of ASU 2016-01 on January 1, 2018 to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted after December 15, 2018. We do not expect the adoption of ASU 2016-13 on January 1, 2020 to have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, or ASU 2016-15, which intends to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of ASU 2016-15 on January 1, 2018 to have a material impact on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, or ASU 2016-16, which removes the prohibition in ASC 740, Income Taxes , against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU 2016-16 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of ASU 2016-16 on January 1, 2018 to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment , or ASU 2017-04, which eliminates Step 2 from the goodwill impairment test and allows an entity to perform its goodwill impairment test by comparing the fair value of a reporting segment with its carrying amount. ASU 2017-04 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. We early adopted ASU 2017-04 on January 1, 2017, which did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, or ASU 2017-09, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Modification accounting is only applied if the value, the vesting conditions or the classification of the award (or equity or liability) changes as a result of the change in terms or conditions. ASU 2017-09 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted. We do not expect the adoption of ASU 2017-09 on January 1, 2018 to have a material impact on our consolidated financial statements.

We estimate the fair value of these purchase option assets by discounting the difference between the applicable property’s acquisition date fair value and an estimate of its future option price. We do not amortize the resulting intangible asset over the term of the lease, but rather adjust the recognized value of the asset upon purchase. In 2017 , we exercised the right to acquire several leased facilities and the value of the purchased option assets utilized was $11,454,000 .
