Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	DESCRIPTION OF BUSINESS Unless the context otherwise requires, “we,” “our” and “us” refer to Black Creek Diversified Property Fund Inc. and its consolidated subsidiaries. Black Creek Diversified Property Fund Inc. is a Maryland corporation formed on April 11, 2005. We are primarily focused on investing in and operating a diverse portfolio of real property. Although we generally target investments in four primary property categories (office, retail, industrial and multifamily), our charter and bylaws do not preclude us from investing in other types of commercial property, real estate debt, or real estate-related equity securities. As of December 31, 2018 , our real estate portfolio consisted of 47 properties, which includes four properties that are part of the DST Program, as defined in “Note 5.” We operate three reportable segments: retail, office and industrial. See “Note 14” for information regarding the financial results by segment. We believe we have operated in such a manner as to qualify as a real estate investment trust (“REIT”) for federal income tax purposes, and we intend to continue to operate in accordance with the requirements for qualification as a REIT. We utilize an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) organizational structure to hold all or substantially all of our assets through an operating partnership, Black Creek Diversified Operating Partnership LP (the “Operating Partnership”), of which we are the sole general partner and a limited partner. We are currently offering shares pursuant to a public offering and intend to operate as a perpetual-life REIT, which means that we intend to offer shares continuously through our ongoing primary offerings and our distribution reinvestment plan. See “Note 8” for detail regarding our public offerings.

Future Minimum Rentals Future minimum base rental payments, which equal the cash basis of monthly contractual rent, owed to us from our tenants under the terms of non-cancelable operating and ground leases in effect as of December 31, 2018 , excluding rental revenues from the potential renewal or replacement of existing leases and from future tenant reimbursement revenue, were as follows for the next five years and thereafter: (in thousands) Future Minimum Rentals 2019 $ 133,999 2020 116,145 2021 104,997 2022 88,136 2023 74,661 Thereafter 323,040 Total $ 840,978 Real Estate Property Impairment During the year ended December 31, 2018, we recorded a $1.2 million non-cash impairment charge related to a consolidated retail property located in the Greater Boston market. Prior to the disposition, we reevaluated the fair value of the property and determined that the net book value of the property exceeded the respective contract sales price less costs to sell the property, resulting in the impairment. The property was disposed of in December 2018. Also during the year ended December 31, 2018, we recorded a total of $13.4 million of non-cash impairment charges related to two retail properties, one located in the Jacksonville, Florida market, which was disposed of in October 2018, and one located in the Holbrook, Massachusetts market, which remains in our operating portfolio. The impairment was a result of shortened hold periods based on the consideration of potential disposition options for these properties. Both ultimately resulted in the reduction of our estimated future cash flows below our net book value. During the year ended December 31, 2017, we recorded a $1.1 million non-cash impairment charge related to a consolidated retail property located in the Greater Boston market. Prior to the disposition, we reevaluated the fair value of the property and determined that the net book value of the property exceeded the respective contract sales price less costs to sell the property, resulting in the impairment. The property was disposed of in May 2017. During the year ended December 31, 2016, we recorded a total of $2.7 million of non-cash impairment charges related to two consolidated properties that we disposed of in 2016. The dispositions consisted of: an office property located in the Washington, DC market and an office property located in the Chicago market. Prior to the disposition of each property, we reevaluated the fair value of the property and determined that the net book value of the property exceeded the respective contract sales price less costs to sell the property, resulting in the impairment. We have determined that our impairments are non-recurring fair value measurements that fall within Level 3 of the fair value hierarchy. See “Note 2” for further discussion of the fair value hierarchy.

In the opinion of management, the accompanying consolidated financial statements contain all adjustments and eliminations, consisting only of normal recurring adjustments necessary for a fair presentation in conformity with GAAP. Basis of Consolidation The consolidated financial statements include the accounts of Black Creek Diversified Property Fund Inc., the Operating Partnership, their wholly-owned subsidiaries, including a taxable REIT subsidiary, and their consolidated joint ventures, as well as amounts related to noncontrolling interests. See “Noncontrolling Interests” below for further detail concerning the accounting policies regarding noncontrolling interests. All material intercompany accounts and transactions have been eliminated. The Operating Partnership meets the criteria of a variable interest entity (“VIE”) as the Operating Partnership’s limited partners do not have the right to remove the general partner and do not have substantive participating rights in the operations of the Operating Partnership. Pursuant to the operating partnership agreement, we are the primary beneficiary of the Operating Partnership as we have the obligation to absorb losses and receive benefits, and the power to control substantially all of the activities which most significantly impact the economic performance of the Operating Partnership. As such, the Operating Partnership continues to be consolidated within our consolidated financial statements. Use of Estimates GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from these estimates. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period they are determined to be necessary. Reclassifications Certain items in our consolidated balance sheets for 2017 have been reclassified to conform to the 2018 presentation. Net financing obligations have been reclassified from other liabilities and are presented as a separate line item on the consolidated balance sheets. Certain items in our consolidated statements of cash flows for 2017 and 2016 have been reclassified to conform to the 2018 presentation. Due to a new accounting standard adopted as of January 1, 2018, restricted cash and restricted cash equivalents have been reclassified to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. Additionally, financing obligations have been reclassified from other financing activities and are presented as a separate line item on the consolidated statements of cash flows. Investment in Real Estate Properties We first determine whether an acquisition constitutes a business or asset acquisition. Upon either a business or asset acquisition, the purchase price of a property is allocated to land, building, and intangible lease assets and liabilities. The allocation of the purchase price to building is based on management’s estimate of the property’s “as-if” vacant fair value. The “as-if” vacant fair value is determined by using all available information such as the replacement cost of such asset, appraisals, property condition reports, market data and other related information. The allocation of the purchase price to intangible lease assets represents the value associated with the in-place leases, which may include lost rent, leasing commissions, tenant improvements, legal and other related costs. The allocation of the purchase price to above-market lease assets and below-market lease liabilities results from in-place leases being above or below management’s estimate of fair market rental rates at the acquisition date and are measured over a period equal to the remaining term of the lease for above-market leases and the remaining term of the lease, plus the term of any below-market fixed-rate renewal option periods, if applicable, for below-market leases. Intangible lease assets, above-market lease assets, and below-market lease liabilities are collectively referred to as “intangible lease assets and liabilities.” If any debt is assumed in an acquisition, the difference between the fair value and the face value of debt is recorded as a premium or discount and amortized to interest expense over the life of the debt assumed. No debt was assumed in connection with our 2018 and 2017 acquisitions. Transaction costs associated with the acquisition of a property are capitalized as incurred in an asset acquisition and are allocated to land, building and intangible lease assets on a relative fair value basis. Properties that are probable to be sold are to be designated as “held for sale” on the consolidated balance sheets when certain criteria are met. The results of operations for acquired properties are included in the consolidated statements of operations from their respective acquisition dates. Intangible lease assets are amortized to real estate-related depreciation and amortization over the remaining lease term. Above-market lease assets are amortized as a reduction in rental revenues over the remaining lease term and below-market lease liabilities are amortized as an increase in rental revenues over the remaining lease term, plus any applicable fixed-rate renewal option periods. We expense any unamortized intangible lease asset or record an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability when a tenant terminates a lease before the stated lease expiration date. During the years ended December 31, 2018 , 2017 and 2016 , we recorded $0.5 million , $2.1 million and $1.7 million , respectively, related to write-offs of unamortized intangible lease assets and liabilities due to early lease terminations. Land, building, building and land improvements, tenant improvements, lease commissions, and intangible lease assets and liabilities, which are collectively referred to as “real estate assets,” are stated at historical cost less accumulated depreciation and amortization. Costs associated with the development and improvement of our real estate assets are capitalized as incurred. These costs include capitalized interest, insurance, real estate taxes and certain general and administrative expenses if such costs are incremental and identifiable to a specific activity to prepare the real estate asset for its intended use. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. Real estate-related depreciation and amortization are computed on a straight-line basis over the estimated useful lives as describe in the following table: Land Not depreciated Building 40 years Building and land improvements 10-40 years Tenant improvements Lesser of useful life or lease term Lease commissions Over lease term Intangible in-place lease assets Over lease term Above-market lease assets Over lease term Below-market lease liabilities Over lease term, including below-market fixed-rate renewal options Real estate assets that are determined to be held and used will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, and we will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value. Refer to “Note 3” for detail regarding the non-cash impairment charges recorded during the years ended December 31, 2018 , 2017 and 2016 . Debt-Related Investments Debt-related investments are considered to be held for investment, as we have both the intent and ability to hold these investments until maturity. Accordingly, these assets are carried at cost, net of unamortized loan origination costs and fees, discounts, repayments and unfunded commitments unless such loans or investments are deemed to be impaired. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of three months or less, such as money market mutual funds or certificates of deposit. We may have bank balances in excess of federally insured amounts; however, we deposit our cash and cash equivalents with high credit-quality institutions to minimize credit risk. Restricted Cash Restricted cash consists primarily of lender and property-related escrow accounts. Straight-Line Rent and Tenant Receivables Straight-line rent and tenant receivables include all straight-line rent and accounts receivable, net of allowances. We record an allowance for estimated losses that may result from the inability of certain of our tenants to make required payments. If a tenant fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances. As of December 31, 2018 and 2017 , our straight-line rent and tenant receivables were approximately $31.6 million and $28.4 million , respectively, and our allowance for doubtful accounts was approximately $0.6 million and $1.1 million , respectively. These amounts are included in our other assets on the consolidated balance sheets. Derivative Instruments We record our derivative instruments at fair value. The accounting for changes in fair value of derivative instruments depends on whether it has been designated and qualifies as a hedge and, if so, the type of hedge. Our interest rate swap derivative instruments are designated as cash flow hedges and are used to hedge exposure to variability in expected future interest payments. The change in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) on the consolidated balance sheets and is subsequently reclassified into earnings as interest expense for the period that the hedged forecasted transaction affects earnings, which is when the interest expense is recognized on the related debt. Our interest rate cap derivative instruments are not designated as hedges and therefore, changes in fair value must be recognized through income. We do not use derivative instruments for trading or speculative purposes. Deferred Financing Costs Deferred financing costs include fees and costs incurred to obtain long-term financing. These fees and costs are amortized to interest expense over the expected terms of the related credit facilities. Unamortized deferred financing costs are written off if debt is retired before its expected maturity date. Accumulated amortization of deferred financing costs was approximately $10.6 million and $6.5 million as of December 31, 2018 and 2017 , respectively. Our interest expense for the years ended December 31, 2018 , 2017 and 2016 included $4.1 million , $2.8 million and $1.8 million , respectively, of amortization of financing costs. Distribution Fees Distribution fees are paid monthly. Distribution fees are accrued upon the issuance of Class T, Class S and Class D shares. As of the balance sheet date, we accrue for: (i) the monthly amount payable, and (ii) the estimated amount of distribution fees that we may pay in future periods. The accrued distribution fees are reflected in additional paid-in capital in stockholders’ equity . See “Note 10” for additional information regarding when distribution fees become payable. Noncontrolling Interests Due to our control of the Operating Partnership through our sole general partner interest and our limited partner interest, we consolidate the Operating Partnership. The remaining limited partner interests in the Operating Partnership are owned by third-party investors and are presented as noncontrolling interests in the consolidated financial statements. The noncontrolling interests are reported on the consolidated balance sheets within permanent equity, separate from stockholders’ equity. Revenue Recognition We record rental revenue on a straight-line basis over the full lease term. Certain properties have leases that offer the tenant a period of time where no rent is due or where rent payments change during the term of the lease. Accordingly, we record receivables from tenants for rent that we expect to collect over the remaining lease term rather than currently, which are recorded as a straight-line rent receivable. When we acquire a property, the term of each existing lease is considered to commence as of the acquisition date for purposes of this calculation. Tenant reimbursement revenue includes payments and amounts due from tenants pursuant to their leases for real estate taxes, insurance and other recoverable property operating expenses and is recognized as rental revenue in the period the applicable expenses are incurred. For the years ended December 31, 2018 , 2017 and 2016 , tenant reimbursement revenue recognized in rental revenues was approximately $38.8 million , $42.6 million and $43.6 million , respectively. In connection with property acquisitions, we may acquire leases with rental rates above or below estimated market rental rates. Above-market lease assets are amortized as a reduction to rental revenue over the remaining lease term, and below-market lease liabilities are amortized as an increase to rental revenue over the remaining lease term, plus any applicable fixed-rate renewal option periods. We expense any unamortized intangible lease asset or record an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability by reassessing the estimated remaining useful life of such intangible lease asset or liability when it becomes probable a tenant will terminate a lease before the stated lease expiration date. Upon disposition of a real estate asset, we will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine proper timing of recognizing gains or losses. Income Taxes We elected under the Internal Revenue Code of 1986, as amended, to be taxed as a REIT beginning with the tax year ended December 31, 2006. As a REIT, we generally are not subject to federal income taxes on net income we distribute to our stockholders. We intend to make timely distributions sufficient to satisfy the annual distribution requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate tax rates. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property and federal income and excise taxes on our undistributed income. Net Income (Loss) Per Share Basic net income (loss) per common share is determined by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per common share includes the effects of potentially issuable common stock, but only if dilutive, including the presumed exchange of partnership interest in the Operating Partnership (“OP Units”). See “Note 11” for additional information regarding net income (loss) per share. Fair Value Measurements Fair value measurements are determined based on assumptions that market participants would use in pricing of assets or estimating liabilities. Fair value measurements are categorized into one of three levels of the fair value hierarchy based on the lowest level of significant input used. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Considerable judgment and a high degree of subjectivity are involved in developing these estimates. These estimates may differ from the actual amounts that we could realize upon settlement. The fair value hierarchy is as follows: Level 1—Quoted (unadjusted) prices in active markets for identical assets or liabilities. Level 2—Other observable inputs, either directly or indirectly, other than quoted prices included in Level 1, including: • Quoted prices for similar assets/liabilities in active markets; • Quoted prices for identical or similar assets/liabilities in non-active markets (e.g., few transactions, limited information, non-current prices, high variability over time); • Inputs other than quoted prices that are observable for the asset/liability (e.g., interest rates, yield curves, volatilities, default rates); and • Inputs that are derived principally from or corroborated by other observable market data. Level 3—Unobservable inputs that cannot be corroborated by observable market data. Concentration of Credit Risk As our revenues predominately consist of rental payments, we are dependent on our tenants for our source of revenues. Concentration of credit risk arises when our source of revenue is highly concentrated from certain of our tenants. As of December 31, 2018 , no tenants represented more than 10.0% of our total annualized base rent. Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which provides guidance for revenue recognition and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition.” The standard is based on the principle that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The guidance specifically excludes revenue derived from lease contracts from its scope. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We adopted the standard when it became effective for us, as of the reporting period beginning January 1, 2018. We elected the package of practical expedients, and accordingly did not reallocate contract consideration to lease components within the scope of the existing lease guidance when we adopted ASU 2014-09. We previously recognized revenue from asset sales upon transfer of title at the time of closing. After adoption of ASU 2014-09, we will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine proper timing of revenue recognition, as well as transaction price allocation. The adoption of ASU 2014-09 did not have a significant impact on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”), which requires: (i) all equity investments to be measured at fair value with changes in fair value recognized in net income; (ii) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (iii) eliminates the requirement for public entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. Early adoption was permitted for the accounting guidance on financial liabilities under the fair value option. We adopted this guidance effective January 1, 2018. The adoption of this guidance did not have a significant impact on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15 “Statement of Cash Flows (Topic 230)” (“ASU 2016-15”), which provided guidance on eight cash flow classification issues and on reducing diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Current GAAP does not include specific guidance on these eight cash flow classification issues. In November 2016, the FASB issued ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash,” (“ASU 2016-18”) which requires companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 requires a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the statement of financial position includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalents balances are required to disclose the nature of the restrictions. We adopted these standards when they became effective for us, as of the beginning of the reporting period beginning January 1, 2018, and as required, retrospectively applied the guidance in ASU 2016-18 to the prior periods presented. For the years ended December 31, 2017 and December 31, 2016 , the adoption resulted in a decrease of $5.3 million and $2.9 million in net cash provided by operating activities, respectively, an increase of $1.3 million and a decrease of $9.3 million in net cash provided by investing activities, respectively, and a decrease of $5.3 million and $1.1 million in net cash used in financing activities, respectively, on the consolidated statements of cash flows. In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. We adopted ASU 2017-12 as of the reporting period beginning on January 1, 2018, which resulted in the recognition of a $0.2 million adjustment to accumulated other comprehensive income with a corresponding adjustment to the January 1, 2018 retained earnings balance related to the cumulative fair value of the financial instruments deemed ineffective. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. Certain disclosures in ASU 2018-13 are required to be applied on a retrospective basis and others on a prospective basis. We early adopted this standard effective September 30, 2018, as permitted. The adoption of ASU 2018-13 did not have a significant impact on our consolidated financial statements. Recently Issued Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases (Subtopic 842)” (“ASU 2016-02”), which provides guidance for greater transparency in financial reporting by organizations that lease assets such as real estate, airplanes and manufacturing equipment by requiring such organizations to recognize lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The accounting for lessors will remain largely unchanged from current GAAP; however, the standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, certain of these costs are capitalizable and therefore this new standard will result in certain of these costs being expensed as incurred after adoption. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted the standard when it became effective for us, as of the reporting period beginning January 1, 2019, and we elected the practical expedients available for implementation under the standard. Under the practical expedients election, we are not required to reassess: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for expired or existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. The standard also requires new disclosures within the notes accompanying the consolidated financial statements. Additionally, in January 2018, the FASB issued ASU No. 2018-01, “Leases (Subtopic 842): Land Easement Practical Expedient for Transition to Topic 842” (“ASU 2018-01”), which updates ASU 2016-02 to include land easements under the updated guidance, including the option to elect the practical expedient discussed above. We also adopted ASU 2018-01 when it became effective for us, as of the reporting period beginning January 1, 2019, and we elected the practical expedients available for implementation under the standard. In addition, in December 2018, the FASB issued ASU No. 2018-20, “Narrow—Scope Improvements for Lessors” (“ASU 2018-20”), which updates 2016-02 by providing the option to elect a practical expedient for lessors to exclude sales and other similar taxes from the transaction price of the contract, allows lessors to exclude from revenue and expense lessor costs paid directly to a third party by lessees, and clarifies lessors’ accounting for variable payments related to both lease and non-lease components. We adopted ASU 2018-20 when it became effective for us, as of the reporting period beginning January 1, 2019, and we elected the practical expedients available for implementation under the standard. The adoption of these standards does not have a material effect on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326)” (“ASU 2016-13”), which introduces a new model for recognizing credit losses for certain financial instruments, including loans, accounts receivable and debt securities. The new model requires an estimate of expected credit losses over the life of exposure to be recorded through the establishment of an allowance account, which is presented as an offset to the related financial asset. The expected credit loss is recorded upon the initial recognition of the financial asset. In November 2018, the FASB issued ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses” (“ASU 2018-19”), which clarifies the scope of the guidance in the amendments in ASU 2016-13. Both ASU 2016-13 and ASU 2018-19 will be effective for annual and interim reporting periods beginning after December 15, 2019, with earlier adoption permitted. The guidance will generally be adopted on a modified retrospective basis, with exceptions for certain types of financial assets. We plan on adopting ASU 2016-13 and ASU 2018-19 as of the reporting period beginning on January 1, 2020. We do not expect the adoption to have a significant impact on our consolidated financial statements.

Debt

Debt	12 Months Ended
	Dec. 31, 2018
Debt Disclosure [Abstract]
Debt	DEBT Our debt is currently comprised of borrowings under our line of credit, term loans and mortgage notes. Borrowings under the non-recourse mortgage notes are secured by mortgages or deeds of trust and related assignments and security interests in collateralized and certain cross-collateralized properties, which are generally owned by single purpose entities. Three of our mortgage notes are currently partial recourse to us, for which we provide the following limited guaranties: $0.4 million in connection with certain outstanding leasing costs, which will decrease as the costs are subsequently paid; and $4.1 million and $3.2 million that is each guaranteed until we meet a lender-specified percentage leased threshold at the respective collateralized property. Other than these limited guarantees, the assets and credit of each of our consolidated properties pledged as collateral for our mortgage notes are not available to satisfy our debt and obligations, unless we first satisfy the mortgages note payable on the respective underlying properties. A summary of our debt is as follows: Weighted-Average Effective Interest Rate as of Balance as of ($ in thousands) December 31, 2018 December 31, 2017 Maturity Date December 31, 2018 December 31, 2017 Line of credit (1) 4.05% 3.27% January 2019 $ 131,000 $ 142,000 Term loan (2) 3.52% 3.25% January 2019 275,000 275,000 Term loan (3) 3.79% 3.94% February 2022 200,000 200,000 Fixed-rate mortgage notes (4) 3.57% 3.89% September 2021 - December 2029 173,932 123,794 Floating-rate mortgage notes (5) 4.97% 3.88% January 2020 - September 2020 225,600 278,100 Total principal amount / weighted-average (6) 3.98% 3.64% $ 1,005,532 $ 1,018,894 Less unamortized debt issuance costs $ (4,627 ) $ (7,322 ) Add mark-to-market adjustment on assumed debt 393 536 Total debt, net $ 1,001,298 $ 1,012,108 Gross book value of properties encumbered by debt $ 598,978 $ 590,542 (1) The effective interest rate is calculated based on the London Interbank Offered Rate (“LIBOR”), plus a margin ranging from 1.40% to 2.30% , depending on our consolidated leverage ratio. As of December 31, 2018 , the unused and available portions under the line of credit were approximately $269.0 million and $207.2 million , respectively. The line of credit is available for general business purposes including, but not limited to, refinancing of existing indebtedness and financing the acquisition of permitted investments, including commercial properties. In January 2019, we amended and restated our existing credit facility agreement. Refer to “Note 16” for details. (2) The effective interest rate is calculated based on LIBOR, plus a margin ranging from 1.35% to 2.20% , depending on our consolidated leverage ratio. The weighted-average interest rate is the all-in interest rate, including the effects of interest swap agreements relating to approximately $150.0 million in borrowings under this term loan. In January 2019, we amended and restated our existing credit facility agreement. Refer to “Note 16” for details. (3) The effective interest rate is calculated based on LIBOR, plus a margin ranging from 1.65% to 2.55% , depending on our consolidated leverage ratio. The weighted-average interest rate is the all-in interest rate and is fixed through interest swap agreements. In January 2019, we amended and restated our existing term loan credit agreement. Refer to “Note 16” for details. (4) The amount outstanding as of December 31, 2018 includes a $32.4 million floating-rate mortgage note that was subject to an interest rate spread of 1.60% over one-month LIBOR, which we have effectively fixed using an interest rate swap at 3.05% until the designated cash flow hedge expires in December 2022, and a $52.1 million floating-rate mortgage note that was subject to an interest rate spread of 1.65% over one-month LIBOR, which we have effectively fixed using an interest rate swap at 2.85% until the designated cash flow hedge expires in July 2021. These mortgage notes expire in March 2023 and August 2023, respectively. (5) The effective interest rate is calculated based on LIBOR plus a margin. As of December 31, 2018 and 2017 , our floating-rate mortgage notes were subject to a weighted-average interest rate spread of 2.47% and 2.31% , respectively. (6) The weighted-average remaining term of our borrowings was approximately 1.9 years as of December 31, 2018 , excluding the impact of certain extension options. As of December 31, 2018 , the principal payments due on our debt during each of the next five years and thereafter were as follows: (in thousands) Line of Credit Term Loans Mortgage Notes Total 2019 (1) $ 131,000 $ 275,000 $ 3,344 $ 409,344 2020 — — 229,088 229,088 2021 — — 12,372 12,372 2022 (2) — 200,000 3,246 203,246 2023 — — 77,463 77,463 Thereafter — — 74,019 74,019 Total principal payments $ 131,000 $ 475,000 $ 399,532 $ 1,005,532 (1) In January 2019, we amended and restated our existing credit facility agreement, which included extending the maturity date of the line of credit to January 2023 with two six -month extension options, subject to certain conditions, and the term loan to January 2024. Refer to “Note 16” for details. (2) In January 2019, we amended and restated this term loan, which resulted in the addition of two one -year extension options, subject to certain conditions. The original maturity date of February 2022 remains unchanged. Refer to “Note 16” for details. Debt Covenants Our line of credit, term loans and mortgage note agreements contain various property-level covenants, including customary affirmative and negative covenants. In addition, the line of credit and term loan agreements contain certain corporate level financial covenants, including leverage ratio, fixed charge coverage ratio, and tangible net worth thresholds. We were in compliance with our debt covenants as of December 31, 2018 . Derivative Instruments To manage interest rate risk for certain of our variable-rate debt, we use interest rate derivative instruments as part of our risk management strategy. These derivatives are designed to mitigate the risk of future interest rate increases by either providing a fixed interest rate or capping the variable interest rate for a limited, pre-determined period of time. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the interest rate swap agreements without exchange of the underlying notional amount. Interest rate caps involve the receipt of variable amounts from a counterparty at the end of each period in which the interest rate exceeds the agreed fixed price. Interest rate caps are not designated as hedges. Certain of our variable-rate borrowings are not hedged, and therefore, to an extent, we have on-going exposure to interest rate movements. During the next 12 months, we estimate that approximately $3.4 million will be reclassified as a decrease to interest expense related to active effective hedges of existing floating-rate debt, and we estimate that approximately $0.4 million will be reclassified as an increase to interest expense related to terminated hedges where the likelihood of the originally hedged interest payments remain probable.

DST Program

DST Program	12 Months Ended
	Dec. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
DST Program	DST PROGRAM We have a program to raise capital through private placement offerings by selling beneficial interests in specific Delaware statutory trusts holding real properties (the “DST Program”). Under the DST Program, each private placement offers interests in one or more real properties placed into one or more Delaware statutory trust(s) by the Operating Partnership or its affiliates (“DST Properties”). DST Properties may be sourced from properties currently indirectly owned by the Operating Partnership or newly acquired properties. The underlying interests of real properties sold to investors pursuant to such private placements are leased-back by an indirect wholly owned subsidiary of the Operating Partnership on a long-term basis. These master lease agreements are fully guaranteed by the Operating Partnership. Additionally, the Operating Partnership retains a fair market value purchase option giving it the right, but not the obligation, to acquire the interests in the Delaware statutory trusts from the investors at a later time in exchange for OP Units. Under the master lease, we are responsible for subleasing the property to occupying tenants and all underlying costs associated with operating the property, and are responsible for paying rent to the Delaware statutory trust that owns such property. As such, for financial reporting purposes (and not for income tax purposes), the DST Properties are included in our consolidated financial statements, with the master lease rent payment obligations taking the place of the cost of equity and debt capital. Accordingly, for financial reporting purposes, the rental revenues and rental expenses associated with the underlying property of each master lease are included in the respective line item on the consolidated statements of operations. Consistent with the foregoing, rental payments made to the Delaware statutory trusts pursuant to the master lease agreements are accounted for using the interest method whereby a portion is accounted for as interest expense and a portion is accounted for as an accretion or amortization of the outstanding principal balance of the financing obligations. The net amount we receive from the underlying properties subject to the master lease may be more or less than the amount we pay to the investors of the DST Program and could fluctuate over time. Consistent with the financial reporting position described herein, the proceeds from each private placement under the DST Program are accounted for as a financing obligation on the consolidated balance sheets due to the fact that we have an option (which may or may not be exercised) to purchase the interests in the Delaware statutory trusts and thereby acquire the real property owned by the Delaware statutory trusts. Consistent with the financial reporting position described herein, upfront costs incurred for services provided by Black Creek Diversified Property Advisors LLC (the “Advisor”) and its affiliates related to the DST Program are accounted for as deferred loan costs and are netted against the financing obligation. During the years ended December 31, 2018, 2017 and 2016, we sold approximately $43.2 million , $9.6 million and $2.5 million , respectively, in interests related to the DST Program. During the years ended December 31, 2018, 2017 and 2016, we incurred rent obligations of approximately $1.1 million , $0.3 million and $38,000 , respectively, under our master lease agreements with the investors who have participated in the DST Program. Refer to “Note 10” for detail relating to the fees paid to the Advisor and its affiliates for raising capital through the DST Program.

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE We estimate the fair value of our financial instruments using available market information and valuation methodologies we believe to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of the amounts that we would realize upon disposition. Fair Value Measurements on a Recurring Basis The following table presents our financial instruments measured at fair value on a recurring basis: (in thousands) Level 1 Level 2 Level 3 Total December 31, 2018 Assets: Derivative instruments $ — $ 6,717 $ — $ 6,717 Total assets measured at fair value $ — $ 6,717 $ — $ 6,717 Liabilities: Derivative instruments $ — $ 3,220 $ — $ 3,220 Total liabilities measured at fair value $ — $ 3,220 $ — $ 3,220 December 31, 2017 Assets: Derivative instruments $ — $ 4,056 $ — $ 4,056 Total assets measured at fair value $ — $ 4,056 $ — $ 4,056 Liabilities: Derivative instruments $ — $ 60 $ — $ 60 Total liabilities measured at fair value $ — $ 60 $ — $ 60 The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Derivative Instruments. The derivative instruments are interest rate swaps and interest rate caps whose fair value is estimated using market-standard valuation models. Such models involve using market-based observable inputs, including interest rate curves. We incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and respective counterparty’s nonperformance risk in the fair value measurements, which we have concluded are not material to the valuation. Due to these derivative instruments being unique and not actively traded, the fair value is classified as Level 2. See “Note 4” above for further discussion of our derivative instruments. Nonrecurring Fair Value Measurements As of December 31, 2018 and 2017 , the fair values of cash and cash equivalents, tenant receivables, due from/to affiliates, accounts payable and accrued liabilities, and distributions payable approximate their carrying values because of the short-term nature of these instruments. The table below includes fair values for certain of our financial instruments for which it is practicable to estimate fair value. The carrying values and fair values of these financial instruments were as follows: As of December 31, 2018 As of December 31, 2017 (in thousands) Carrying Value (1) Fair Value Carrying Fair Assets: Debt-related investments $ 10,682 $ 10,709 $ 11,120 $ 11,250 Liabilities: Line of credit $ 131,000 $ 131,000 $ 142,000 $ 142,000 Term loans 475,000 475,000 475,000 475,000 Mortgage notes 399,532 398,117 401,894 401,574 (1) The carrying amount reflects the principal amount outstanding.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES We have concluded that there was no impact related to uncertain tax positions from our results of operations for the years ended December 31, 2018 , 2017 and 2016 . We had a gross deferred tax asset of approximately $3.9 million and $4.9 million as of December 31, 2018 and 2017 , respectively, which is offset by a full valuation allowance. The U.S. is the major tax jurisdiction for us and the earliest tax year subject to examination by the taxing authority is 2014. Distributions Distributions to stockholders are characterized for federal income tax purposes as: (i) ordinary income; (ii) non-taxable return of capital; or (iii) long-term capital gain. Distributions that exceed our current and accumulated tax earnings and profits constitute a return of capital and reduce the stockholders’ basis in the common shares. To the extent that a distribution exceeds both current and accumulated earnings and profits and the stockholders’ basis in the common shares, the distributions will generally be treated as a gain from the sale or exchange of such stockholders’ common shares. Under the new tax laws effective January 1, 2018, all distributions (other than distributions designated as capital gain distributions and distributions traceable to distributions from a taxable REIT subsidiary) which are received by a pass-through entity or an individual, are eligible for a 20% deduction from gross income. This eligibility for a 20% deduction will expire as of 2025. At the beginning of each year, we notify our stockholders of the taxability of the distributions paid during the preceding year. In any given year, the overall taxability of distributions could be higher or lower than the preceding year. The following unaudited table summarizes the annual information reported to investors regarding the taxability of distributions on common stock, as a percentage of total distributions, for the years ended December 31, 2018 , 2017 and 2016 . This information assumes that an investor owned shares of our common stock for the full 2018 calendar year. For the Year Ended December 31, 2018 (1) 2017 2016 Ordinary income 42.22 % 50.01 % 53.66 % Non-taxable return of capital 57.78 — 46.34 Capital gain — 49.99 — Total distributions 100.00 % 100.00 % 100.00 % (1) Our overall taxability decreased in 2018 as compared to 2017 primarily due to lower disposition activity in 2018, which resulted in a decrease in capital gains generated by the sale of real estate assets.

Equity [Abstract]
Stockholders' Equity	STOCKHOLDERS’ EQUITY Public Offering As a net asset value (“NAV”)-based perpetual life REIT, we intend to conduct ongoing public primary offerings of our common stock on a perpetual basis. We also intend to conduct an ongoing distribution reinvestment plan offering for our stockholders to reinvest distributions in our shares. From time to time, we intend to file new registration statements on Form S-11 with the SEC to register additional shares of common stock so that we may continuously offer shares of common stock pursuant to Rule 415 under the Securities Act of 1933, as amended. Currently, we have the following registration statements effective with the SEC: • A public offering of up to $3.0 billion in Class T, Class S, Class D and Class I shares of common stock, consisting of up to $2.5 billion offered in our primary offering and up to $500.0 million offered under our distribution reinvestment plan. We may reallocate amounts between the primary offering and distribution reinvestment plan. As of December 31, 2018 , $2.9 billion remained unsold under this registration statement. • A public offering of Class E shares under our distribution reinvestment plan. As of December 31, 2018 , $5.8 million remained unsold under this registration statement. The Class T, Class S, Class D, Class I and Class E shares, all of which are collectively referred to herein as shares of common stock, generally have identical rights and privileges, including identical voting rights, but have differing fees that are payable on a class-specific basis. While gross distributions are the same for all share classes, the payment of class-specific fees results in different amounts of net distributions being paid with respect to each class of shares. A summary of our public offerings (including shares sold through the primary offering and distribution reinvestment plan (“DRIP”)), for the year ended December 31, 2018 , is as follows: (in thousands) Class T Class S Class D Class I Class E Total Amount of gross proceeds raised: Primary offering $ 6,732 $ 78,995 $ 3,983 $ 51,382 $ — $ 141,092 DRIP 480 615 511 7,028 10,355 18,989 Total offering $ 7,212 $ 79,610 $ 4,494 $ 58,410 $ 10,355 $ 160,081 Number of shares sold: Primary offering 878 10,414 531 6,865 — 18,688 DRIP 64 81 68 941 1,385 2,539 Total offering 942 10,495 599 7,806 1,385 21,227 Common Stock The following table describes the changes in each class of common shares during each of the years ended December 31, 2018 , 2017 and 2016 : (in thousands) Class T Shares (1) Class S Shares (1) Class D Shares (1) Class I Shares (1) Class E Shares (1) Total Shares (1) Balances as of December 31, 2015 1,703 N/A 1,812 23,334 137,275 164,124 Issuance of common stock: Primary shares 436 — 782 10,960 — 12,178 Distribution reinvestment plan 42 — 44 684 2,004 2,774 Share-based compensation — — — 32 — 32 Redemptions of common stock (180 ) — (367 ) (971 ) (26,954 ) (28,472 ) Balances as of December 31, 2016 2,001 N/A 2,271 34,039 112,325 150,636 Issuance of common stock: Primary shares 134 64 267 2,181 — 2,646 Distribution reinvestment plan 63 — 73 1,036 1,934 3,106 Share-based compensation — — — (99 ) — (99 ) Redemptions of common stock (136 ) — (101 ) (3,022 ) (20,564 ) (23,823 ) Balances as of December 31, 2017 2,062 64 2,510 34,135 93,695 132,466 Issuance of common stock: Primary shares 878 10,414 531 6,865 — 18,688 Distribution reinvestment plan 64 81 68 941 1,385 2,539 Share-based compensation — — — 42 — 42 Redemptions of common stock (221 ) (43 ) (331 ) (4,598 ) (17,690 ) (22,883 ) Balances as of December 31, 2018 2,783 10,516 2,778 37,385 77,390 130,852 (1) On September 1, 2017, we amended our charter and restructured our outstanding share classes as part of a broader restructuring. As part of the restructuring, we, among other things, changed our outstanding unclassified shares of common stock (which, since 2012, we referred to as “Class E” shares ) to a new formally designated class of Class E shares; changed our outstanding Class A, Class W and Class I shares of common stock to Class T, Class D and a new version of Class I shares of common stock, respectively; and created a new class of common stock called Class S shares. When we refer to our share classes in this table with respect to dates prior to September 1, 2017, we are referring to our shares under our prior share structure, and when we refer to our share classes in this table with respect to dates on or after September 1, 2017, we are referring to our shares under our new share structure. Distributions Prior to the third quarter of 2017, distributions were paid on a quarterly basis and were calculated for each day the stockholder had been a stockholder of record during such quarter. Beginning with the third quarter of 2017, cash distributions have been paid on a monthly basis and are calculated as of monthly record dates. Cash distributions for stockholders who had elected to participate in our distribution reinvestment plan were reinvested into shares of the same class of our common stock as the shares to which the distributions relate. The following table summarizes our distribution activity (including distributions to noncontrolling interests and distributions reinvested in shares of our common stock) for the quarters ended below: Amount (in thousands, except per share data) Declared per Common Share (1) Common Stock Distributions Paid in Cash Other Cash Distributions (2) Reinvested in Shares Total Distributions 2018 March 31 $ 0.09375 $ 7,240 $ 1,127 $ 4,789 $ 13,156 June 30 0.09375 7,137 1,221 4,710 13,068 September 30 0.09375 7,157 1,174 4,738 13,069 December 31 0.09375 7,180 1,202 4,814 13,196 Total $ 0.37500 $ 28,714 $ 4,724 $ 19,051 $ 52,489 2017 March 31 $ 0.09000 $ 8,289 $ 1,250 $ 5,076 $ 14,615 June 30 0.09000 8,027 1,300 4,920 14,247 September 30 0.09000 7,549 1,195 4,937 13,681 December 31 0.09000 7,285 1,088 4,775 13,148 Total $ 0.36000 $ 31,150 $ 4,833 $ 19,708 $ 55,691 (1) Amount reflects the total quarterly distribution rate, subject to adjustment for class-specific fees.

See “Note 10” for further detail regarding the current and historical ongoing distribution fees. Redemptions and Repurchases Below is a summary of redemptions and repurchases pursuant to our share redemption program for the years ended December 31, 2018 , 2017 and 2016 . Also included in the summary below is the impact of stock repurchases pursuant to our two self-tender offers. Our board of directors may modify, suspend or terminate our current share redemption programs if it deems such action to be in the best interest of our stockholders.

Noncontrolling Interests	NONCONTROLLING INTERESTS OP Units As of December 31, 2018 and 2017 , the Operating Partnership had issued OP Units to third-party investors, representing 7.4% and 7.9% , respectively, of limited partnership interests. Currently, all of the third-party investors own Class E OP Units, but we may in the future cause the Operating Partnership to issue Class T, Class S, Class D or Class I OP Units to third-party investors. The following table summarizes the number of OP Units issued and outstanding to third-party investors: As of December 31, (in thousands) 2018 2017 Number of OP Units issued and outstanding to third-party investors 10,482 11,292 Estimated maximum redemption value (unaudited) $ 77,962 $ 83,647 Subject to certain restrictions and limitations, the holders of OP Units may redeem all or a portion of their OP Units for either: shares of the equivalent class of common stock, cash or a combination of both. If we elect to redeem OP Units for shares of our common stock, we will generally deliver one share of our common stock for each such OP Unit redeemed (subject to any redemption fees withheld), and such shares may, subsequently, only be redeemed for cash in accordance with the terms of our share redemption program. If we elect to redeem OP Units for cash, the cash delivered will equal the then-current NAV per unit of the applicable class of OP Units (subject to any redemption fees withheld), which will equal the then-current NAV per share of our corresponding class of shares. The following table summarizes the number of OP Units redeemed during the years presented below: For the Year Ended December 31, (in thousands) 2018 2017 2016 Number of OP Units redeemed 810 756 760 Amount of OP Units redeemed $ 6,059 $ 5,643 $ 5,641 The Operating Partnership’s net income and loss will generally be allocated to the general partner and the limited partners in accordance with the respective percentage interest in the OP Units issued by the Operating Partnership.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS We rely on the Advisor, a related party, to manage our day-to-day activities and to implement our investment strategy pursuant to the terms of the amended and restated advisory agreement, effective as of June 30, 2018, by and among us, the Operating Partnership and the Advisor (the “Advisory Agreement”). The current term of the Advisory Agreement ends June 30, 2019, subject to renewals by our board of directors for an unlimited number of successive one -year periods. The Dealer Manager provides dealer manager services in connection with our public offerings pursuant to the terms of the third amended and restated dealer manager agreement, effective September 1, 2017 (the “Dealer Manager Agreement”) by and among us, the Advisor and the Dealer Manager. Black Creek Diversified Property Advisors Group LLC (the “Sponsor”), which owns the Advisor, is presently directly or indirectly majority owned by the estate of John A. Blumberg, James R. Mulvihill and Evan H. Zucker and/or their affiliates, and the Sponsor and the Advisor are jointly controlled by the estate of Mr. Blumberg, Mr. Mulvihill and Mr. Zucker and/or their affiliates. The Dealer Manager is presently directly or indirectly majority owned, controlled and/or managed by the estate of Mr. Blumberg, Mr. Mulvihill and/or Mr. Zucker and/or their affiliates. The Advisor and the Dealer Manager receive compensation from us in the form of fees and expense reimbursements for certain services relating to our public offerings and for the investment and management of our assets and our other activities and operations. Advisory Agreement, Dealer Manager Agreement and Operating Partnership Agreement The following is a description of the fees and expense reimbursements payable to the Advisor and the Dealer Manager. This summary does not purport to be a complete summary of the Advisory Agreement; the Dealer Manager Agreement; and the limited partnership agreement of the Operating Partnership (the “Operating Partnership Agreement”), and is qualified in its entirety by reference to such agreements, which are incorporated by reference as exhibits to this Annual Report on Form 10-K. Selling Commissions, Dealer Manager Fees and Distribution Fees. We pay the Dealer Manager upfront selling commissions with respect to Class T and Class S shares sold in the primary offering and dealer manager fees with respect to Class T shares sold in the primary offering. The upfront selling commissions and dealer manager fees are calculated as a percentage of the transaction price (generally equal to the most recent monthly NAV per share) at the time of purchase of such shares. All or a portion of the upfront selling commissions and dealer manager fees will be retained by, or reallowed to, participating broker dealers. In addition, the Dealer Manager is entitled to receive ongoing distribution fees based on the NAV of all outstanding Class T, Class S and Class D shares, including shares issued under our distribution reinvestment plan. The distribution fees will be payable monthly in arrears and will be paid on a continuous basis from year to year. The Dealer Manager will reallow all or a portion of the distribution fees to participating broker dealers and broker dealers servicing accounts of investors who own Class T, Class S, and/or Class D shares. The following table details the selling commissions, dealer manager fees and distribution fees applicable for each share class. Class T Class S Class D Class I Selling commissions (as % of transaction price) up to 3.00% up to 3.50% —% —% Dealer manager fees (as % of transaction price) 0.50% —% —% —% Distribution fees (as % of NAV per annum) 0.85% 0.85% 0.25% —% We will cease paying the distribution fees with respect to individual Class T, Class S and Class D shares when they are no longer outstanding, including as a result of a conversion to Class I shares. Each Class T, Class S or Class D share held within a stockholder’s account shall automatically and without any action on the part of the holder thereof convert into a number of Class I shares at the applicable conversion rate on the earliest of: (i) a listing of any shares of our common stock on a national securities exchange; (ii) our merger or consolidation with or into another entity, or the sale or other disposition of all or substantially all of our assets; and (iii) the end of the month in which the Dealer Manager, in conjunction with our transfer agent, determines that the total upfront selling commissions, upfront dealer manager fees and ongoing distribution fees paid with respect to all shares of such class held by such stockholder within such account (including shares purchased through the distribution reinvestment plan or received as stock dividends) equals or exceeds 8.75% (or a lower limit set forth in any applicable agreement between the Dealer Manager and a participating broker dealer, provided that the Dealer Manager advises our transfer agent of the lower limit in writing) of the aggregate purchase price of all shares of such class held by such stockholder within such account and purchased in a primary offering. Additional Underwriting Compensation and Primary Dealer Fee. We pay directly, or reimburse the Advisor and the Dealer Manager if they pay on our behalf, certain additional items of underwriting compensation, including legal fees of the Dealer Manager, costs reimbursement for registered representatives of participating broker-dealers to attend educational conferences sponsored by us or the Dealer Manager, attendance fees for registered persons associated with the Dealer Manager to attend seminars conducted by participating broker-dealers, and promotional items. In addition to this additional underwriting compensation, the Advisor may also pay the Dealer Manager additional amounts to fund certain of the Dealer Manager’s costs and expenses related to the distribution of our public offering, which will not be reimbursed by us. Also, the Dealer Manager may pay supplemental fees or commissions to participating broker-dealers and servicing broker-dealers with respect to Class I shares sold in the primary offering, which will not be reimbursed by us. Through June 30, 2017, we paid to the Dealer Manager primary dealer fees in the amount of 5.0% of the gross proceeds raised from certain sales of Class I shares in the primary offering. We currently do not intend to pay additional primary dealer fees in our public offerings. Organization and Offering Expense Reimbursement. We pay directly or reimburse the Advisor and the Dealer Manager if they pay on our behalf, any issuer organization and offering expenses (meaning organization and offering expenses other than underwriting compensation) as and when incurred. After the termination of the primary offering and again after termination of the offering under our distribution reinvestment plan, the Advisor has agreed to reimburse us to the extent that total cumulative organization and offering expenses (including underwriting compensation) that we incur exceed 15% of our gross proceeds from the applicable offering. Advisory Fee and Operating Expense Reimbursement. The advisory fee consists of a fixed component and a performance component. The fixed component of the advisory fee includes a fee that will be paid monthly to the Advisor for asset management services provided to on our behalf. The following table details the fixed component of the advisory fee: Fixed Component % of applicable monthly NAV per Fund Interest (as defined below) x the weighted-average number of Fund Interests for such month (per annum) 1.10% % of consideration received by us or our affiliates for selling interests in DST Properties (as defined in “Note 5”) to third-party investors, net of up-front fees and expense reimbursements payable out of gross sale proceeds from the sale of such interests 1.10% The performance component of the advisory fee is a performance-based amount that will be paid to the Advisor. This amount is calculated on the basis of the overall investment return provided to holders of Fund Interests (i.e., our outstanding shares and OP Units held by third-party investors) in any calendar year such that the Advisor will receive the lesser of (1) 12.5% of (a) the annual total return amount less (b) any loss carryforward, and (2) the amount equal to (x) the annual total return amount, less (y) any loss carryforward, less (z) the amount needed to achieve an annual total return amount equal to 5% of the NAV per Fund Interest at the beginning of such year (the “Hurdle Amount”). The foregoing calculations are calculated on a per Fund Interest basis and multiplied by the weighted-average Fund Interests outstanding during the year. In no event will the performance component of the advisory fee be less than zero. Accordingly, if the annual total return amount exceeds the Hurdle Amount plus the amount of any loss carryforward, then the Advisor will earn a performance component equal to 100% of such excess, but limited to 12.5% of the annual total return amount that is in excess of the loss carryforward. The “annual total return amount” referred to above means all distributions paid or accrued per Fund Interest plus any change in NAV per Fund Interest since the end of the prior calendar year, adjusted to exclude the negative impact on annual total return resulting from our payment or obligation to pay, or distribute, as applicable, the performance component of the advisory fee as well as ongoing distribution fees (i.e., our ongoing class-specific fees).The “loss carryforward” referred to above will track any negative annual total return amounts from prior years and offset the positive annual total return amount for purposes of the calculation of the performance component of the advisory fee. The loss carryforward is zero as of December 31, 2018 . Additionally, the Advisor will provide us with a waiver of a portion of its fees generally equal to the amount of the performance component that would have been payable with respect to the Class E shares and the Series 1 Class E OP Units held by third parties until the NAV of such shares or units exceeds $10.00 a share or unit, the benefit of which will be shared among all holders of Fund Interests. As of December 31, 2018 , all of the Class E OP Units issued and outstanding to third-party investors are Series 1 Class E OP Units. Refer to “Note 9” for detail regarding the Class E OP Units. Subject to certain limitations, we reimburse the Advisor or its affiliates for all of the costs they incur in connection with the services they provide to us under the Advisory Agreement, including, without limitation, our allocable share of the Advisor’s overhead, which includes but is not limited to the Advisor’s rent paid to both third parties and affiliates of the Advisor, utilities and personnel costs; provided, that we will not reimburse the Advisor or its affiliates for services for which the Advisor or its affiliates are entitled to compensation in the form of a separate fee, and commencing as of September 1, 2017, we will not reimburse the Advisor for compensation it pays to our named executive officers. Fees from Other Services. We retain certain of the Advisor’s affiliates, from time to time, for services relating to our investments or our operations, which may include property management services, leasing services, corporate services, statutory services, transaction support services, construction and development management, and loan management and servicing, and within one or more such categories, providing services in respect of asset and/or investment administration, accounting, technology, tax preparation, finance, treasury, operational coordination, risk management, insurance placement, human resources, legal and compliance, valuation and reporting-related services, as well as services related to mortgage servicing, group purchasing, healthcare, consulting/brokerage, capital markets/credit origination, property, title and/or other types of insurance, management consulting and other similar operational matters. Any fees paid to the Advisor’s affiliates for any such services will not reduce the advisory fees. Per the terms of the agreement, any such arrangements will be at market rates or a reimbursement of costs incurred by the affiliate in providing the services. DST Program DST Program Dealer Manager Fees. In connection with the DST Program, as described in “Note 5,” Black Creek Exchange LLC (“BCX”), a wholly-owned subsidiary of our taxable REIT subsidiary that is wholly-owned by the Operating Partnership, entered into a dealer manager agreement with the Dealer Manager, pursuant to which the Dealer Manager agreed to conduct the private placements for interests reflecting an indirect ownership of up to $500.0 million of interests. The Advisor, Dealer Manager and certain of their affiliates receive fees and reimbursements in connection with their roles in the DST Program, which costs are substantially funded by the private investors in that program, through one or more purchase price “mark-ups” of the initial estimated fair value of the DST Properties to be sold to investors, fees paid by the investors at the time of investment, or deductions from distributions paid to such investors. BCX will pay certain up-front fees and reimburse certain related expenses to the Dealer Manager with respect to capital raised through the DST Program. BCX is obligated to pay the Dealer Manager a dealer manager fee of up to 1.5% of gross equity proceeds raised and a commission of up to 5.0% of gross equity proceeds raised through the private placements. In addition, with respect to certain classes of interests (or the corresponding classes of OP Units or shares for which they may be exchanged in certain circumstances) we, the Operating Partnership or BCX will pay the Dealer Manager ongoing fees in amounts up to 0.85% of the equity investment or net asset value thereof per year. The Dealer Manager may re-allow such commissions, ongoing fees and a portion of such dealer manager fees to participating broker dealers. In addition, pursuant to the dealer manager agreement for the DST Program, we, or our subsidiaries, are obligated to reimburse the Dealer Manager for (a) customary travel, lodging, meals and reasonable entertainment expenses incurred in connection with the private placements; (b) costs and expenses of conducting educational conferences and seminars, attending broker-dealer sponsored conferences, or educational conferences sponsored by BCX; (c) customary promotional items; and (d) legal fees of the Dealer Manager. Pursuant to the Advisory Agreement, DST Properties are included when calculating the fixed and performance components of the advisory fee due to the Advisor. Furthermore, because the Advisor funds certain Dealer Manager personnel costs that are not reimbursed under the DST Program dealer manager agreement, we have also agreed to pay the Advisor a fee equal to the mark-up paid by DST Program investors for these costs, which is up to 1.5% of the total equity amount paid for the interests. DST Manager Fees. BC Exchange Manager LLC (the “DST Manager”), a wholly owned subsidiary of the Operating Partnership, acts, directly or through a wholly-owned subsidiary, as the manager of each Delaware statutory trust holding a DST Property, but has assigned all of its rights and obligations as manager (including fees and reimbursements received) to BC Exchange Advisor LLC (“DST Advisor”), an affiliate of the Advisor. While the intention is to sell 100% of the interests to third parties, BCX may hold an interest for a period of time and therefore could be subject to the following description of fees and reimbursements paid to the DST Manager. The DST Manager will have primary responsibility for performing administrative actions in connection with the trust and any DST Property and has the sole power to determine when it is appropriate for a trust to sell a DST Property. For its services, DST Advisor will receive, through the DST Manager, (i) a management fee equal to a stated percentage (e.g., 1.0%) of the gross rents payable to the trust, with such amount to be set on a deal-by-deal basis, (ii) a disposition fee of up to 1.0% of the gross sales price of any DST Property sold to a third party, (iii) a loan fee of up to 1.0% for any financing provided by us in connection with the DST Program (in which case a subsidiary of ours would provide the debt financing and earn interest thereon), (iv) reimbursement of certain expenses associated with the establishment, maintenance and operation of the trust and DST Properties and the sale of any DST Property to a third party, and (v) up to 1.0% of the gross equity proceeds as compensation for developing and maintaining the DST Program technology and intellectual property. Furthermore, to the extent that the Operating Partnership exercises its fair market value purchase option to acquire the interests from the investors at a later time in exchange for OP Units, and such investors subsequently submit such OP Units for redemption pursuant to the terms of the Operating Partnership, a redemption fee of up to 1.0% of the amount otherwise payable to a limited partner upon redemption will be paid to DST Manager (or such other amount as may be set forth in the applicable DST Program offering documents). Product Specialist Pursuant to a product specialist agreement with BCG TRT Advisors LLC (“BCG TRT Advisors”), BCG TRT Advisors provides advisory services related to our investments in real estate securities. Pursuant to this agreement, a portion of the fixed component of the advisory fee that the Advisor receives from us (as described above) related to investments in real estate securities is reallowed to BCG TRT Advisors in exchange for the services provided. Summary of Fees and Expenses The following table summarizes the fees and expenses incurred by us for services provided by the Advisor and its affiliates, and by the Dealer Manager related to the services described above, and any related amounts payable: For the Year Ended December 31, Payable as of December 31, (in thousands) 2018 2017 2016 2018 2017 Upfront selling commissions $ 1,199 $ 34 $ 100 $ — $ — Dealer manager fees (1)(2) — 306 381 — — Ongoing distribution fees (2) 501 108 70 76 15 Primary dealer fees — — 3,465 — — Advisory fees (3) 13,836 13,191 14,857 3,225 954 Advisory fees related to the disposition of real properties (4) — 1,763 2,140 — — Other expense reimbursements—Advisor (5)(6) 8,801 8,393 8,368 1,411 1,988 Other expense reimbursements—Dealer Manager 878 401 377 — — Development management fees (7) — — 31 — — DST Program advisory fees (8) 313 94 — — — DST Program selling commissions 1,097 466 117 — — DST Program dealer manager fees 293 143 38 — — DST Program other reimbursements—Dealer Manager 212 137 19 — — DST Program facilitation and loan origination fees 356 — — — — Total $ 27,486 $ 25,036 $ 29,963 $ 4,712 $ 2,957 (1) Includes upfront dealer manager fees, as well as ongoing dealer manager fees that were paid under the Dealer Manager Agreement in effect prior to September 1, 2017. (2) The distribution fees accrue daily and are payable monthly in arrears. Additionally, we accrue for future estimated amounts payable related to ongoing distribution fees. The future estimated amounts payable of approximately $7.9 million and $1.9 million as of December 31, 2018 and 2017 , respectively, are included in other liabilities on the consolidated balance sheets. Prior to September 1, 2017, the future estimated amounts payable included ongoing dealer manager fees. (3) Amount for the years December 31, 2018 , 2017 and 2016 included in advisory fees, related party on the consolidated statements of operations. Of these total amounts, included are approximately $0.5 million , $0.7 million and $1.1 million , respectively, that we were not obligated to pay in consideration of the issuance of Company RSUs to the Advisor. See “Advisor RSU Agreements” below for more detail. (4) Amounts for the years December 31, 2017 and 2016 include approximately $1.7 million and $1.9 million , respectively, and are included in gain on sale of real property on the consolidated statements of operations. For the year ended December 31, 2017 , we paid the Advisor approximately $1.4 million in consideration for disposition services rendered prior to September 1, 2017 for which the Advisor had not otherwise been paid a fee, of which $1.2 million is included in gain on sale of real property on the consolidated statements of operations and $0.2 million was deferred in other assets on the consolidated balance sheets until the occurrence of future dispositions. Additionally, for the years December 31, 2017 and 2016 , amounts include approximately $45,000 and $265,000 , respectively, paid to the Advisor for advisory fees associated with the disposition of real properties, which are included in impairment of real estate property on the consolidated statements of operations. Pursuant to the Advisory Agreement, effective September 1, 2017, the Advisor no longer receives disposition fees. (5) Amounts include approximately $6.6 million , $6.6 million and $6.8 million for the years ended December 31, 2018 , 2017 and 2016 , respectively, related to the reimbursement of a portion of the salary, bonus and benefits for employees of the Advisor, including our named executive officers, for services provided to us for which the Advisor does not otherwise receive a separate fee. A portion of compensation received by certain employees of the Advisor and its affiliates may be in the form of a restricted stock grant awarded by us. We show these as reimbursements to the Advisor to the same extent that we recognize the related share-based compensation on our consolidated statements of operations. The balance of such reimbursements is made up primarily of other general overhead and administrative expenses, including, but not limited to, allocated rent paid to both third parties and affiliates of the Advisor, equipment, utilities, insurance, travel and entertainment, and other costs, which are included in general and administrative expenses on the consolidated statements of income. As of September 1, 2017, we no longer reimburse salary, bonus and benefits of our named executive officers. However, we will reimburse the Advisor for bonuses of our named executive offers for services provided to us prior to September 1, 2017 upon the final determination and payment of such bonuses to our named executive officers during the first quarter of 2018. (6) Includes costs reimbursed to the Advisor related to the DST Program. (7) Pursuant to the Advisory Agreement, effective September 1, 2017, the Advisor no longer receives a development management fee. (8) Amount for the years December 31, 2018 , 2017 and 2016 included in advisory fees, related party on the consolidated statements of operations. Equity Incentive Plans Our equity incentive plans provide for the potential granting of cash-based awards and stock-based awards, including stock options, stock appreciation rights, restricted stock, and stock units to our employees (if we have any in the future), our independent directors, employees of the Advisor or its affiliates, other advisors and consultants of ours and of the Advisor selected by the plan administrator for participation in the equity incentive plans, and any prospective director, officer, employee, consultant, or advisor of the Company and the Advisor. Any such stock-based awards, including stock options, stock appreciation rights, restricted stock, and stock units, if granted, will provide for exercise prices, where applicable, that are not less than the fair market value of shares of our common stock on the date of the grant. At each annual meeting of stockholders the independent directors automatically, upon election, receive an award, pursuant to our equity incentive plans, of $10,000 in RSUs with respect to Class I shares of our common stock, with the number of RSUs based on the NAV per Class I share as of the end of the day of the annual meeting. Advisor RSU Agreements Pursuant to the terms of Restricted Stock Unit Agreements with the Advisor (the “Advisor RSU Agreements”), we have granted restricted stock units (“Company RSUs”) to the Advisor in exchange for certain advisory fee and expense reimbursement offsets. No additional grants are scheduled at this time. Each Company RSU will, upon vesting, be settled in one share of our Class I common stock. The Company RSUs are subject to specified vesting and settlement provisions and, upon settlement in Class I shares of our common stock, require offsets of advisory fees and expenses otherwise payable by us to the Advisor based on a value of the NAV per Class I share on the grant date of the applicable Company RSU. As of December 31, 2018 , approximately 0.6 million of the Class I shares that were issued upon settlement of Company RSUs have been used for fee offset over the past five years . These Company RSUs are expected to be reallowed by the Advisor to its senior management. The purposes of the Advisor RSU Agreements are to promote an alignment of interests among our stockholders, the Advisor and the personnel of the Advisor and its affiliates, and to promote retention of the personnel of the Advisor and its affiliates. The Advisor has entered into agreements to redistribute substantially all of the Class I shares acquired through Company RSUs to senior level employees of the Advisor and its affiliates that provide services to us, although the terms of such redistributions (including the timing, amount and recipients) remain solely in the discretion of the Advisor. The table below summarizes the unvested Company RSUs as of December 31, 2018 : (in thousands, except per share data) Grant Date Vesting Date Number of Unvested Shares Grant Date NAV per Class I Share Company RSUs 2/4/2016 4/15/2019 57 $ 7.41 On each vesting date, an offset amount will be calculated and deducted on a pro rata basis over the next 12 months from the cash payments otherwise due and payable to the Advisor under our then-current Advisory Agreement for any fees or expense reimbursements. Each offset amount will equal the number of Company RSUs vesting on such date multiplied by the grant-date NAV per Class I share. For each Company RSU, the offset amount will always be calculated based on the grant-date NAV per Class I share, even beyond the initial grant and vesting dates. At the end of each 12-month period following each vesting date, if the offset amount has not been fully realized by offsets from the cash payments otherwise due and payable to the Advisor under the Advisory Agreement, the Advisor will promptly pay any shortfall to us. The Advisor RSU Agreements will automatically terminate upon termination or non-renewal of the Advisory Agreement, by any party for any reason. In addition, upon a change in control of us, then either the Advisor or we may immediately terminate the Advisor RSU Agreements. Further, the Advisor may immediately terminate the Advisor RSU Agreements if we exercise certain rights under the Advisor RSU Agreements to replace the Company RSUs with another form of compensation. Upon termination of the Advisor RSU Agreements, the Advisor will promptly pay any unused offset amounts to us or, at the Advisor’s election, return Class I shares in equal value based on the Class I NAV as of the date of termination of the Advisor RSU Agreements. In addition, upon termination of the Advisor RSU Agreements, all unvested Company RSUs will be forfeited except that, unless the Advisor RSU Agreements were terminated at the election of the Advisor following a change in control of us or as a result of a premature termination of the Advisory Agreement at our election for cause (as defined in the Advisory Agreement) or upon the bankruptcy of the Advisor, then following such forfeiture of Company RSUs, the Advisor will have the right to acquire from us the number of Class I shares equal to the number of Company RSUs forfeited, in return for a purchase price equal to such number of Class I shares multiplied by the grant-date NAV per Class I share. The Advisor must notify us of its election to exercise the foregoing acquisition right within 30 days following the termination of the Advisor RSU Agreements, and the parties will close the transaction within 60 days following the termination of the Advisor RSU Agreements. If our board of directors declares and we pay a cash dividend on Class I shares for any period in which the Company RSUs are outstanding (regardless of whether such Company RSUs are then vested), the Advisor will be entitled to dividend equivalents with respect to that cash dividend equal to the cash dividends that would have been payable on the same number of Class I shares as the number of Company RSUs subject to the Advisor RSU Agreements had such Class I shares been outstanding during the same portion of such period as the Company RSUs were outstanding. Any such dividend equivalents may be paid in cash or Class I shares, at the Advisor’s election. Transactions with Affiliates We initially contributed $2,000 into the Operating Partnership in exchange for 200 OP Units, representing the sole general partner interest in the Operating Partnership. Subsequently, we contributed 100% of the gross proceeds received from our public offerings of common stock to the Operating Partnership in exchange for OP Units representing our interest as a limited partner of the Operating Partnership. As of December 31, 2018 and 2017 , we held a 92.6% and 92.1% , respectively, limited partnership interest in the Operating Partnership. The remaining limited partnership interests in the Operating Partnership are held by third-party investors, which are classified as noncontrolling interests on the consolidated balance sheets. See “Note 9” for detail regarding our noncontrolling interests.

Environmental Matters A majority of the properties we acquire are subject to environmental reviews either by us or the previous owners. In addition, we may incur environmental remediation costs associated with certain land parcels we may acquire in connection with the development of the land. We have acquired certain properties in urban and industrial areas that may have been leased to or previously owned by commercial and industrial companies that discharged hazardous materials. We may purchase various environmental insurance policies to mitigate our exposure to environmental liabilities. We are not aware of any environmental liabilities that we believe would have a material adverse effect on our business, financial condition, or results of operations as of December 31, 2018 .

Segment Financial Information

Segment Reporting [Abstract]
Segment Financial Information	SEGMENT FINANCIAL INFORMATION Our three reportable segments are office, retail and industrial. Factors used to determine our reportable segments include the physical and economic characteristics of our properties and the related operating activities. Our chief operating decision makers rely primarily on net operating income to make decisions about allocating resources and assessing segment performance. Net operating income is the key performance metric that captures the unique operating characteristics of each segment. Items that are not directly assignable to a segment, such as certain corporate items, are not allocated but reflected as reconciling items. The following table sets forth the financial results by segment for the years ended December 31, 2018 , 2017 and 2016 : (in thousands) Office Retail Industrial Corporate Consolidated 2018 Rental revenues $ 108,421 $ 73,416 $ 7,794 $ — $ 189,631 Rental expenses (42,544 ) (17,618 ) (1,505 ) — (61,667 ) Net operating income $ 65,877 $ 55,798 $ 6,289 $ — $ 127,964 Real estate-related depreciation and amortization $ 33,335 $ 20,616 $ 3,915 $ — $ 57,866 Total assets $ 724,875 $ 671,007 $ 111,230 $ 73,990 $ 1,581,102 2017 Rental revenues $ 108,305 $ 81,871 $ 6,342 $ — $ 196,518 Rental expenses (44,520 ) (20,388 ) (1,624 ) — (66,532 ) Net operating income $ 63,785 $ 61,483 $ 4,718 $ — $ 129,986 Real estate-related depreciation and amortization $ 41,283 $ 24,216 $ 2,571 $ — $ 68,070 Total assets $ 775,917 $ 705,696 $ 58,657 $ 67,836 $ 1,608,106 2016 Rental revenues $ 126,782 $ 82,372 $ 6,073 $ — $ 215,227 Rental expenses (42,482 ) (21,355 ) (1,750 ) — (65,587 ) Net operating income $ 84,300 $ 61,017 $ 4,323 $ — $ 149,640 Real estate-related depreciation and amortization $ 50,996 $ 26,142 $ 2,967 $ — $ 80,105 Total assets $ 825,961 $ 827,799 $ 57,651 $ 72,317 $ 1,783,728 We consider net operating income to be an appropriate supplemental performance measure and believe net operating income provides useful information to our investors regarding our financial condition and results of operations because net operating income reflects the operating performance of our properties and excludes certain items that are not considered to be controllable in connection with the management of the properties, such as real estate-related depreciation and amortization, general and administrative expenses, advisory fees, acquisition expenses, impairment charges, interest expense, gains on sale of properties, other income and expense, gains and losses on the extinguishment of debt and noncontrolling interests. However, net operating income should not be viewed as an alternative measure of our financial performance since it excludes such items, which could materially impact our results of operations. Further, our net operating income may not be comparable to that of other real estate companies, as they may use different methodologies for calculating net operating income. Therefore, we believe net income, as defined by GAAP, to be the most appropriate measure to evaluate our overall financial performance. The following table is a reconciliation of our reported net income attributable to common stockholders to our net operating income for the years ended December 31, 2018 , 2017 and 2016 . For the Year Ended December 31, (in thousands) 2018 2017 2016 Net (loss) income attributable to common stockholders $ (1,237 ) $ 72,216 $ 49,976 Debt-related income (694 ) (828 ) (943 ) Real estate-related depreciation and amortization 57,866 68,070 80,105 General and administrative expenses 8,817 9,235 9,450 Advisory fees, related party 14,149 13,285 14,857 Acquisition expenses — — 667 Impairment of real estate property 14,648 1,116 2,677 Other expense (income) 251 462 (2,207 ) Interest expense 48,358 42,305 40,782 Gain on extinguishment of debt — — (5,136 ) Gain on sale of real property (14,093 ) (83,057 ) (45,660 ) Net (loss) income attributable to noncontrolling interests (101 ) 7,182 5,072 Net operating income $ 127,964 $ 129,986 $ 149,640

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS Debt On January 11, 2019, we amended and restated our existing senior unsecured revolving and term credit facility agreement by entering into a $450.0 million line of credit and a $325.0 million term loan, for an aggregate amount of $775.0 million . The maturity date of the line of credit was extended to January 31, 2023 and contains two six -month extension options, subject to certain conditions. The effective interest rate for the line of credit is calculated based on the LIBOR, plus a margin ranging from 1.30% to 2.10% , depending on our consolidated leverage ratio. The maturity date of the term loan was extended to January 31, 2024 and the effective interest rate for the term loan is based on LIBOR, plus a margin ranging from 1.25% to 2.05% , depending on our consolidated leverage ratio. As of January 11, 2019, we had $250.0 million and $150.0 million outstanding under this line of credit and term loan, respectively. We also amended and restated our existing senior unsecured term loan agreement on January 11, 2019, by entering into a $200.0 million term loan. The maturity date for this term loan is February 27, 2022, and contains two one -year extension options, subject to certain conditions. The primary interest rate for this term loan is based on LIBOR, plus a margin ranging from 1.25% to 2.05% , depending on our consolidated leverage ratio. As of January 11, 2019, we had $200.0 million outstanding under this term loan. Agreement to Sell Property On February 8, 2019, we entered into an agreement to sell an office property located in San Francisco, California (“655 Montgomery”) to an unrelated third party for a gross sales price of approximately $191.5 million . 655 Montgomery is encumbered by a mortgage note and a mezzanine loan secured by a pledge of ownership interests in this property, which we expect to prepay at par upon the closing of this transaction. As of December 31, 2018, the mortgage note and mezzanine loan had an aggregate outstanding principal balance of approximately $98.6 million with a weighted-average variable interest rate of 5.25% and both mature in September 2020. The closing of this transaction is subject to various contingencies, and we cannot provide assurance whether or when this transaction will occur. The current outside closing date is May 6, 2019, although such closing may occur earlier upon satisfaction of certain conditions.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying consolidated financial statements contain all adjustments and eliminations, consisting only of normal recurring adjustments necessary for a fair presentation in conformity with GAAP.
Principles of Consolidation	Basis of Consolidation The consolidated financial statements include the accounts of Black Creek Diversified Property Fund Inc., the Operating Partnership, their wholly-owned subsidiaries, including a taxable REIT subsidiary, and their consolidated joint ventures, as well as amounts related to noncontrolling interests. See “Noncontrolling Interests” below for further detail concerning the accounting policies regarding noncontrolling interests. All material intercompany accounts and transactions have been eliminated. The Operating Partnership meets the criteria of a variable interest entity (“VIE”) as the Operating Partnership’s limited partners do not have the right to remove the general partner and do not have substantive participating rights in the operations of the Operating Partnership. Pursuant to the operating partnership agreement, we are the primary beneficiary of the Operating Partnership as we have the obligation to absorb losses and receive benefits, and the power to control substantially all of the activities which most significantly impact the economic performance of the Operating Partnership. As such, the Operating Partnership continues to be consolidated within our consolidated financial statements.
Use of Estimates	Use of Estimates GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from these estimates. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period they are determined to be necessary.
Reclassifications	Reclassifications Certain items in our consolidated balance sheets for 2017 have been reclassified to conform to the 2018 presentation. Net financing obligations have been reclassified from other liabilities and are presented as a separate line item on the consolidated balance sheets. Certain items in our consolidated statements of cash flows for 2017 and 2016 have been reclassified to conform to the 2018 presentation. Due to a new accounting standard adopted as of January 1, 2018, restricted cash and restricted cash equivalents have been reclassified to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. Additionally, financing obligations have been reclassified from other financing activities and are presented as a separate line item on the consolidated statements of cash flows.
Investment In Real Estate Properties	Investment in Real Estate Properties We first determine whether an acquisition constitutes a business or asset acquisition. Upon either a business or asset acquisition, the purchase price of a property is allocated to land, building, and intangible lease assets and liabilities. The allocation of the purchase price to building is based on management’s estimate of the property’s “as-if” vacant fair value. The “as-if” vacant fair value is determined by using all available information such as the replacement cost of such asset, appraisals, property condition reports, market data and other related information. The allocation of the purchase price to intangible lease assets represents the value associated with the in-place leases, which may include lost rent, leasing commissions, tenant improvements, legal and other related costs. The allocation of the purchase price to above-market lease assets and below-market lease liabilities results from in-place leases being above or below management’s estimate of fair market rental rates at the acquisition date and are measured over a period equal to the remaining term of the lease for above-market leases and the remaining term of the lease, plus the term of any below-market fixed-rate renewal option periods, if applicable, for below-market leases. Intangible lease assets, above-market lease assets, and below-market lease liabilities are collectively referred to as “intangible lease assets and liabilities.” If any debt is assumed in an acquisition, the difference between the fair value and the face value of debt is recorded as a premium or discount and amortized to interest expense over the life of the debt assumed. No debt was assumed in connection with our 2018 and 2017 acquisitions. Transaction costs associated with the acquisition of a property are capitalized as incurred in an asset acquisition and are allocated to land, building and intangible lease assets on a relative fair value basis. Properties that are probable to be sold are to be designated as “held for sale” on the consolidated balance sheets when certain criteria are met. The results of operations for acquired properties are included in the consolidated statements of operations from their respective acquisition dates. Intangible lease assets are amortized to real estate-related depreciation and amortization over the remaining lease term. Above-market lease assets are amortized as a reduction in rental revenues over the remaining lease term and below-market lease liabilities are amortized as an increase in rental revenues over the remaining lease term, plus any applicable fixed-rate renewal option periods. We expense any unamortized intangible lease asset or record an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability when a tenant terminates a lease before the stated lease expiration date. During the years ended December 31, 2018 , 2017 and 2016 , we recorded $0.5 million , $2.1 million and $1.7 million , respectively, related to write-offs of unamortized intangible lease assets and liabilities due to early lease terminations. Land, building, building and land improvements, tenant improvements, lease commissions, and intangible lease assets and liabilities, which are collectively referred to as “real estate assets,” are stated at historical cost less accumulated depreciation and amortization. Costs associated with the development and improvement of our real estate assets are capitalized as incurred. These costs include capitalized interest, insurance, real estate taxes and certain general and administrative expenses if such costs are incremental and identifiable to a specific activity to prepare the real estate asset for its intended use. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. Real estate-related depreciation and amortization are computed on a straight-line basis over the estimated useful lives as describe in the following table: Land Not depreciated Building 40 years Building and land improvements 10-40 years Tenant improvements Lesser of useful life or lease term Lease commissions Over lease term Intangible in-place lease assets Over lease term Above-market lease assets Over lease term Below-market lease liabilities Over lease term, including below-market fixed-rate renewal options Real estate assets that are determined to be held and used will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, and we will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value. Refer to “Note 3” for detail regarding the non-cash impairment charges recorded during the years ended December 31, 2018 , 2017 and 2016 .
Debt-Related Investments	Debt-Related Investments Debt-related investments are considered to be held for investment, as we have both the intent and ability to hold these investments until maturity. Accordingly, these assets are carried at cost, net of unamortized loan origination costs and fees, discounts, repayments and unfunded commitments unless such loans or investments are deemed to be impaired.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of three months or less, such as money market mutual funds or certificates of deposit. We may have bank balances in excess of federally insured amounts; however, we deposit our cash and cash equivalents with high credit-quality institutions to minimize credit risk.
Restricted Cash	Restricted Cash Restricted cash consists primarily of lender and property-related escrow accounts.
Straight-Line Rent and Tenant Receivables	Straight-Line Rent and Tenant Receivables Straight-line rent and tenant receivables include all straight-line rent and accounts receivable, net of allowances. We record an allowance for estimated losses that may result from the inability of certain of our tenants to make required payments. If a tenant fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances.
Derivative Instruments	Derivative Instruments We record our derivative instruments at fair value. The accounting for changes in fair value of derivative instruments depends on whether it has been designated and qualifies as a hedge and, if so, the type of hedge. Our interest rate swap derivative instruments are designated as cash flow hedges and are used to hedge exposure to variability in expected future interest payments. The change in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) on the consolidated balance sheets and is subsequently reclassified into earnings as interest expense for the period that the hedged forecasted transaction affects earnings, which is when the interest expense is recognized on the related debt. Our interest rate cap derivative instruments are not designated as hedges and therefore, changes in fair value must be recognized through income. We do not use derivative instruments for trading or speculative purposes.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs include fees and costs incurred to obtain long-term financing. These fees and costs are amortized to interest expense over the expected terms of the related credit facilities. Unamortized deferred financing costs are written off if debt is retired before its expected maturity date.
Distribution Fees	Distribution Fees Distribution fees are paid monthly. Distribution fees are accrued upon the issuance of Class T, Class S and Class D shares. As of the balance sheet date, we accrue for: (i) the monthly amount payable, and (ii) the estimated amount of distribution fees that we may pay in future periods. The accrued distribution fees are reflected in additional paid-in capital in stockholders’ equity . See “Note 10” for additional information regarding when distribution fees become payable.
Noncontrolling Interests	Noncontrolling Interests Due to our control of the Operating Partnership through our sole general partner interest and our limited partner interest, we consolidate the Operating Partnership. The remaining limited partner interests in the Operating Partnership are owned by third-party investors and are presented as noncontrolling interests in the consolidated financial statements. The noncontrolling interests are reported on the consolidated balance sheets within permanent equity, separate from stockholders’ equity.
Revenue Recognition	Revenue Recognition We record rental revenue on a straight-line basis over the full lease term. Certain properties have leases that offer the tenant a period of time where no rent is due or where rent payments change during the term of the lease. Accordingly, we record receivables from tenants for rent that we expect to collect over the remaining lease term rather than currently, which are recorded as a straight-line rent receivable. When we acquire a property, the term of each existing lease is considered to commence as of the acquisition date for purposes of this calculation. Tenant reimbursement revenue includes payments and amounts due from tenants pursuant to their leases for real estate taxes, insurance and other recoverable property operating expenses and is recognized as rental revenue in the period the applicable expenses are incurred. For the years ended December 31, 2018 , 2017 and 2016 , tenant reimbursement revenue recognized in rental revenues was approximately $38.8 million , $42.6 million and $43.6 million , respectively. In connection with property acquisitions, we may acquire leases with rental rates above or below estimated market rental rates. Above-market lease assets are amortized as a reduction to rental revenue over the remaining lease term, and below-market lease liabilities are amortized as an increase to rental revenue over the remaining lease term, plus any applicable fixed-rate renewal option periods. We expense any unamortized intangible lease asset or record an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability by reassessing the estimated remaining useful life of such intangible lease asset or liability when it becomes probable a tenant will terminate a lease before the stated lease expiration date. Upon disposition of a real estate asset, we will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine proper timing of recognizing gains or losses.
Income Taxes	Income Taxes We elected under the Internal Revenue Code of 1986, as amended, to be taxed as a REIT beginning with the tax year ended December 31, 2006. As a REIT, we generally are not subject to federal income taxes on net income we distribute to our stockholders. We intend to make timely distributions sufficient to satisfy the annual distribution requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate tax rates. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property and federal income and excise taxes on our undistributed income.
Net Income (Loss) Per Share	Net Income (Loss) Per Share Basic net income (loss) per common share is determined by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per common share includes the effects of potentially issuable common stock, but only if dilutive, including the presumed exchange of partnership interest in the Operating Partnership (“OP Units”).
Fair Value Measurements	Fair Value Measurements Fair value measurements are determined based on assumptions that market participants would use in pricing of assets or estimating liabilities. Fair value measurements are categorized into one of three levels of the fair value hierarchy based on the lowest level of significant input used. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Considerable judgment and a high degree of subjectivity are involved in developing these estimates. These estimates may differ from the actual amounts that we could realize upon settlement. The fair value hierarchy is as follows: Level 1—Quoted (unadjusted) prices in active markets for identical assets or liabilities. Level 2—Other observable inputs, either directly or indirectly, other than quoted prices included in Level 1, including: • Quoted prices for similar assets/liabilities in active markets; • Quoted prices for identical or similar assets/liabilities in non-active markets (e.g., few transactions, limited information, non-current prices, high variability over time); • Inputs other than quoted prices that are observable for the asset/liability (e.g., interest rates, yield curves, volatilities, default rates); and • Inputs that are derived principally from or corroborated by other observable market data. Level 3—Unobservable inputs that cannot be corroborated by observable market data.
Concentration of Credit Risk	Concentration of Credit Risk As our revenues predominately consist of rental payments, we are dependent on our tenants for our source of revenues. Concentration of credit risk arises when our source of revenue is highly concentrated from certain of our tenants. As of December 31, 2018 , no tenants represented more than 10.0% of our total annualized base rent.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which provides guidance for revenue recognition and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition.” The standard is based on the principle that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The guidance specifically excludes revenue derived from lease contracts from its scope. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We adopted the standard when it became effective for us, as of the reporting period beginning January 1, 2018. We elected the package of practical expedients, and accordingly did not reallocate contract consideration to lease components within the scope of the existing lease guidance when we adopted ASU 2014-09. We previously recognized revenue from asset sales upon transfer of title at the time of closing. After adoption of ASU 2014-09, we will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine proper timing of revenue recognition, as well as transaction price allocation. The adoption of ASU 2014-09 did not have a significant impact on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”), which requires: (i) all equity investments to be measured at fair value with changes in fair value recognized in net income; (ii) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (iii) eliminates the requirement for public entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. Early adoption was permitted for the accounting guidance on financial liabilities under the fair value option. We adopted this guidance effective January 1, 2018. The adoption of this guidance did not have a significant impact on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15 “Statement of Cash Flows (Topic 230)” (“ASU 2016-15”), which provided guidance on eight cash flow classification issues and on reducing diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Current GAAP does not include specific guidance on these eight cash flow classification issues. In November 2016, the FASB issued ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash,” (“ASU 2016-18”) which requires companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 requires a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the statement of financial position includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalents balances are required to disclose the nature of the restrictions. We adopted these standards when they became effective for us, as of the beginning of the reporting period beginning January 1, 2018, and as required, retrospectively applied the guidance in ASU 2016-18 to the prior periods presented. For the years ended December 31, 2017 and December 31, 2016 , the adoption resulted in a decrease of $5.3 million and $2.9 million in net cash provided by operating activities, respectively, an increase of $1.3 million and a decrease of $9.3 million in net cash provided by investing activities, respectively, and a decrease of $5.3 million and $1.1 million in net cash used in financing activities, respectively, on the consolidated statements of cash flows. In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. We adopted ASU 2017-12 as of the reporting period beginning on January 1, 2018, which resulted in the recognition of a $0.2 million adjustment to accumulated other comprehensive income with a corresponding adjustment to the January 1, 2018 retained earnings balance related to the cumulative fair value of the financial instruments deemed ineffective. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. Certain disclosures in ASU 2018-13 are required to be applied on a retrospective basis and others on a prospective basis. We early adopted this standard effective September 30, 2018, as permitted. The adoption of ASU 2018-13 did not have a significant impact on our consolidated financial statements. Recently Issued Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases (Subtopic 842)” (“ASU 2016-02”), which provides guidance for greater transparency in financial reporting by organizations that lease assets such as real estate, airplanes and manufacturing equipment by requiring such organizations to recognize lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The accounting for lessors will remain largely unchanged from current GAAP; however, the standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, certain of these costs are capitalizable and therefore this new standard will result in certain of these costs being expensed as incurred after adoption. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted the standard when it became effective for us, as of the reporting period beginning January 1, 2019, and we elected the practical expedients available for implementation under the standard. Under the practical expedients election, we are not required to reassess: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for expired or existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. The standard also requires new disclosures within the notes accompanying the consolidated financial statements. Additionally, in January 2018, the FASB issued ASU No. 2018-01, “Leases (Subtopic 842): Land Easement Practical Expedient for Transition to Topic 842” (“ASU 2018-01”), which updates ASU 2016-02 to include land easements under the updated guidance, including the option to elect the practical expedient discussed above. We also adopted ASU 2018-01 when it became effective for us, as of the reporting period beginning January 1, 2019, and we elected the practical expedients available for implementation under the standard. In addition, in December 2018, the FASB issued ASU No. 2018-20, “Narrow—Scope Improvements for Lessors” (“ASU 2018-20”), which updates 2016-02 by providing the option to elect a practical expedient for lessors to exclude sales and other similar taxes from the transaction price of the contract, allows lessors to exclude from revenue and expense lessor costs paid directly to a third party by lessees, and clarifies lessors’ accounting for variable payments related to both lease and non-lease components. We adopted ASU 2018-20 when it became effective for us, as of the reporting period beginning January 1, 2019, and we elected the practical expedients available for implementation under the standard. The adoption of these standards does not have a material effect on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326)” (“ASU 2016-13”), which introduces a new model for recognizing credit losses for certain financial instruments, including loans, accounts receivable and debt securities. The new model requires an estimate of expected credit losses over the life of exposure to be recorded through the establishment of an allowance account, which is presented as an offset to the related financial asset. The expected credit loss is recorded upon the initial recognition of the financial asset. In November 2018, the FASB issued ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses” (“ASU 2018-19”), which clarifies the scope of the guidance in the amendments in ASU 2016-13. Both ASU 2016-13 and ASU 2018-19 will be effective for annual and interim reporting periods beginning after December 15, 2019, with earlier adoption permitted. The guidance will generally be adopted on a modified retrospective basis, with exceptions for certain types of financial assets. We plan on adopting ASU 2016-13 and ASU 2018-19 as of the reporting period beginning on January 1, 2020. We do not expect the adoption to have a significant impact on our consolidated financial statements.
DST Program	Under the master lease, we are responsible for subleasing the property to occupying tenants and all underlying costs associated with operating the property, and are responsible for paying rent to the Delaware statutory trust that owns such property. As such, for financial reporting purposes (and not for income tax purposes), the DST Properties are included in our consolidated financial statements, with the master lease rent payment obligations taking the place of the cost of equity and debt capital. Accordingly, for financial reporting purposes, the rental revenues and rental expenses associated with the underlying property of each master lease are included in the respective line item on the consolidated statements of operations. Consistent with the foregoing, rental payments made to the Delaware statutory trusts pursuant to the master lease agreements are accounted for using the interest method whereby a portion is accounted for as interest expense and a portion is accounted for as an accretion or amortization of the outstanding principal balance of the financing obligations. The net amount we receive from the underlying properties subject to the master lease may be more or less than the amount we pay to the investors of the DST Program and could fluctuate over time. Consistent with the financial reporting position described herein, the proceeds from each private placement under the DST Program are accounted for as a financing obligation on the consolidated balance sheets due to the fact that we have an option (which may or may not be exercised) to purchase the interests in the Delaware statutory trusts and thereby acquire the real property owned by the Delaware statutory trusts. Consistent with the financial reporting position described herein, upfront costs incurred for services provided by Black Creek Diversified Property Advisors LLC (the “Advisor”) and its affiliates related to the DST Program are accounted for as deferred loan costs and are netted against the financing obligation.
