Organization and Business Operations	Note 1—Organization and Business Operations
	Carter Validus Mission Critical REIT, Inc., or the Company, a Maryland corporation, was incorporated on December 16, 2009 and currently is treated and qualifies as a real estate investment trust, or a REIT, under the Internal Revenue Code of 1986, as amended, or the Code, for federal income tax purposes. The Company was organized to acquire and operate a diversified portfolio of income producing commercial real estate, with a focus on the data center and healthcare sectors, net leased to investment grade and other creditworthy tenants, as well as to make other real estate investments that relate to such property types. The Company operates through two reportable segments – commercial real estate investments in data centers and healthcare. Substantially all of the Company’s business is conducted through Carter/Validus Operating Partnership, LP, a Delaware limited partnership, or the Operating Partnership. The Company is the sole general partner of the Operating Partnership. Carter/Validus Advisors, LLC, or the Advisor, the Company’s affiliated advisor, is the sole limited partner of the Operating Partnership. As of December 31, 2014, the Company owned 46 real estate investments (including two real estate investments owned through consolidated partnerships), consisting of 58 properties located in 33  metropolitan statistical areas, or MSAs.
	On March 23, 2010, the Company filed a registration statement on Form S-11 under the Securities Act of 1933, as amended, or the Securities Act, to offer for sale to the public on a best efforts basis a maximum of 150,000,000 shares of common stock at a price of $10.00 per share, and up to 25,000,000 additional shares of common stock pursuant to a distribution reinvestment plan, or the DRIP, under which the Company’s stockholders were able to elect to have distributions reinvested in additional shares at the higher of $9.50 per share or 95% of the fair market value per share as determined by the Company’s board of directors, or the Offering, for a maximum offering of up to $1,737,500,000 in shares of common stock. The registration statement for the Offering was first declared effective by the Securities and Exchange Commission, or the SEC, on December 10, 2010.
	On May 16, 2014, the Company reallocated $187,500,000 in shares of common stock from the DRIP to our primary offering. As a result, the Company was authorized to sell a maximum of 168,750,000 shares of common stock at a price of $10.00 per share, and up to 6,250,000 additional shares of common stock pursuant to the DRIP, for a maximum offering of up to $1,746,875,000 in shares of common stock.
	On June 6, 2014, the Offering terminated. The Company raised gross proceeds of approximately $1,716,046,000 in the Offering (including shares of common stock issued pursuant to the DRIP). The Company will continue to issue shares of common stock under the Second DRIP (as defined below) until such time as the Company sells all of the shares registered for sale under the Second DRIP, unless the Company files a new registration statement with the SEC, or the Second DRIP is terminated by the Company’s board of directors. The Company expects that property acquisitions in 2015 and future periods, if any, will be funded by the remaining net proceeds from the Offering, proceeds from the strategic sale of properties or other investments, financing of the acquired properties, net proceeds from the Second DRIP and cash flows from operations.
	On April 14, 2014, the Company filed a registration statement on Form S-3 under the Securities Act to register $100,000,000 in shares of common stock pursuant to a distribution reinvestment plan, or the Second DRIP, which offers existing stockholders a convenient method for purchasing additional shares of common stock by reinvesting cash distributions without paying any selling commissions, fees or service charges. The registration statement became effective with the SEC automatically upon filing; however, the Company did not commence offering shares pursuant to the Second DRIP until June 7, 2014 following the termination of the Offering. As of December 31, 2014, approximately 2,934,000 shares of common stock were issued pursuant to the Second DRIP. As of December 31, 2014, approximately 7,592,000 shares of common stock were remaining in the Second DRIP.
	As of December 31, 2014, the Company had also invested in real estate-related notes receivables in the aggregate principal amount of $23,421,000.  Except as the context otherwise requires, “we,” “our,” “us,” and the “Company” refer to Carter Validus Mission Critical REIT, Inc., the Operating Partnership, all majority-owned subsidiaries and controlled subsidiaries.

	The summary of significant accounting policies presented below is designed to assist in understanding the consolidated financial statements. Such consolidated financial statements and the accompanying notes thereto are the representations of management. These accounting policies conform to accounting principles generally accepted in the United States of America, or GAAP, in all material respects, and have been consistently applied in preparing the consolidated financial statements.
	Principles of Consolidation and Basis of Presentation
	The accompanying consolidated financial statements include the accounts of the Company, the Operating Partnership, all majority-owned subsidiaries and controlled subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	In determining whether the Company has a controlling interest in the entities and the requirement to consolidate the accounts of any such entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the partners/members as well as whether the investment entity is a variable interest entity, or VIE, for which the Company is the primary beneficiary.
	A VIE is a legal entity in which the equity investors do not have the characteristics of a controlling financial interest but is subject to consolidation if the entity (i) has insufficient equity at risk to permit the entity to finance its activities, (ii) whose at risk equity owners, as a group, do not have the power to direct the activities that most significantly impact the entity’s economic performance, or (iii) whose at risk equity owners do not absorb the entity’s losses or receive its returns. The Company consolidates all VIEs for which it is the primary beneficiary. In determining whether the Company is the primary beneficiary of a VIE, it considers if it has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE. Consideration of various factors include, but are not limited to, the Company’s ability to direct the activities that most significantly impact the entity’s economic performance, its form of ownership interest, its representation on the entity’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and to replace the manager of and/or liquidate the entity.
	As of December 31, 2014, the Company consolidated the accounts of one VIE, the 180 Peachtree Data Center, as the Company has the power to direct the activities that most significantly impact the entity’s economic performance, see Note 3—“Real Estate Investments.”
	In addition, the Company evaluates its loan investments to determine if the borrowing entity qualifies as a VIE. As of December 31, 2014, the Company determined that two of its loan investments in real estate-related notes receivables were with entities that qualify as VIEs, of which the Company is not the primary beneficiary because it does not have the ability to direct the activities of the VIEs that most significantly impact the entities’ economic performance. See Note 6—“Real Estate-Related Notes Receivables.”
	Real Estate-Related Notes Receivables
	Real estate-related notes receivables are recorded at stated principal amounts net of any discount or premium and deferred loan origination costs or fees. The related discounts or premiums are accreted or amortized over the life of the real estate-related notes receivables, as applicable. The Company defers certain loan origination and commitment fees and amortizes them as an adjustment of yield over the term of the real estate-related note receivable. The related accretion of discounts and/or amortization of premiums and origination costs are recorded in real estate-related notes receivables interest income in the accompanying consolidated statements of comprehensive income (loss).
	The Company evaluates the collectability of both interest and principal on each real estate-related note receivable, primarily through the evaluation of credit quality indicators such as underlying collateral and payment history. The Company does not intend to sell its investments in real estate-related notes receivables and it is not likely that the Company will be required to sell its investments in real estate-related notes receivables before recovery of their amortized costs basis, which may be at maturity. There were no amounts past due on real estate-related notes receivables as of December 31, 2014. A real estate-related note receivable is considered to be impaired, when based upon current information and events, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. If a real estate-related note receivable is considered to be impaired, the amount of loss is calculated by comparing the recorded investment to the value determined by discounting the expected future cash flows at the real estate-related note receivable’s effective interest rate or to the value of the underlying collateral if the real estate-related note receivable is collateral dependent. Interest income on performing real estate-related notes receivables is accrued as earned. Interest income on an impaired real estate-related note receivable is recognized on a cash basis. Evaluating a real estate-related note receivable for potential impairment can require management to exercise significant judgments. No impairment losses were recorded related to investments in real estate-related notes receivables for the years ended December 31, 2014, 2013 and 2012. In addition, no allowances for uncollectability were recorded related to investments in real estate-related notes receivables as of December 31, 2014 and December 31, 2013.
	Use of Estimates
	The preparation of the consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates.
	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value.
	Restricted Cash Held in Escrow
	Restricted cash held in escrow includes cash held by lenders in escrow accounts for tenant and capital improvements, repairs and maintenance and other lender reserves for certain properties, in accordance with the respective lender’s loan agreement. Contributions and receipts of escrowed funds have been classified as financing activities since such funds are controlled by lenders and serve as collateral for the notes payable. Restricted cash is reported in other assets in the accompanying consolidated balance sheets. See Note 5—“Other Assets.”
	Deferred Financing Costs
	Deferred financing costs are loan fees, legal fees and other third-party costs associated with obtaining financing. These costs are amortized over the terms of the respective financing agreements using the effective interest method. Unamortized deferred financing costs are generally expensed when the associated debt is refinanced or repaid before maturity unless specific rules are met that would allow for the carryover of such costs to the refinanced debt. Costs incurred in seeking financing transactions that do not close are expensed in the period in which it is determined that the financing will not close. Deferred financing costs are reported in other assets in the accompanying consolidated balance sheets. See Note 5—“Other Assets.”
	Investment in Real Estate
	Real estate costs related to the acquisition, development, construction and improvement of properties are capitalized. Repair and maintenance costs are expensed as incurred and significant replacements and betterments are capitalized. Repair and maintenance costs include all costs that do not extend the useful life of the real estate asset. The Company considers the period of future benefit of an asset in determining the appropriate useful life. Real estate assets, other than land, are depreciated or amortized on a straight-line basis over each asset’s useful life. The Company estimated the useful lives of its assets by class as follows:
	Building and improvements	15 – 40 years
	Tenant improvements	Shorter of lease term or expected useful life
	Identified intangible assets	Remaining term of related lease
	Furniture, fixtures, and equipment	3 – 10 years
	Allocation of Purchase Price of Real Estate
	Upon the acquisition of real properties, the Company evaluates whether the acquisition is a business combination or an asset acquisition. The Company determined that properties acquired with an existing lease in place are accounted as a business combination and properties acquired without an existing lease in place are accounted as an asset acquisition.
	Business Combinations
	Upon the acquisition of real properties determined to be business combinations, the Company allocates the purchase price of such properties to acquired tangible assets, consisting of land and buildings, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, based in each case on their estimated fair values.
	The fair values of the tangible assets of an acquired property (which includes the land and buildings and improvements) are determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and buildings and improvements based on management’s determination of the relative fair value of these assets. Management determines the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases, including leasing commissions and other related costs. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses during the expected lease-up periods based on current market conditions.
	The fair values of above-market and below-market in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease including any fixed rate bargain renewal periods, with respect to a below-market lease. The above-market and below-market lease values are capitalized as intangible lease assets or liabilities. Above-market lease values are amortized as an adjustment of rental income over the remaining terms of the respective leases. Below-market leases are amortized as an adjustment of rental income over the remaining terms of the respective leases, including any fixed rate bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above-market and below-market in-place lease values related to that lease would be recorded as an adjustment to rental income.
	The fair values of in-place leases include an estimate of direct costs associated with obtaining a new tenant and opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant include commissions, tenant improvements, and other direct costs and are estimated based on management’s consideration of current market costs to execute a similar lease. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. The in-place lease intangibles are included in real estate assets in the accompanying consolidated balance sheets and amortized to expense over the remaining terms of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.
	Asset Acquisitions
	Upon the acquisition of real estate properties determined to be asset acquisitions, the Company allocates the purchase price of such properties generally to acquired tangible assets, consisting of land and buildings and improvements, based in each case on initial cost of the asset acquired.
	Acquisition Fees and Expenses
	Acquisition fees and expenses in connection with the acquisition of properties determined to be business combinations are expensed as incurred, including investment transactions that are no longer under consideration, and are included in acquisition related expenses in the accompanying consolidated statements of comprehensive income (loss). Acquisition fees and expenses associated with transactions determined to be an asset acquisitions are capitalized.
	Impairment of Long Lived Assets
	The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of its real estate and related intangible assets may not be recoverable. When indicators of potential impairment suggest that the carrying value of real estate and related intangible assets may not be recoverable, the Company assesses the recoverability of the assets by estimating whether the Company will recover the carrying value of the asset through its undiscounted future cash flows and its eventual disposition. If based on this analysis the Company does not believe that it will be able to recover the carrying value of the asset, the Company will record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the asset. No impairment losses have been recorded to date.
	When developing estimates of expected future cash flows, the Company makes certain assumptions regarding future market rental income amounts subsequent to the expiration of current lease arrangements, property operating expenses, terminal capitalization and discount rates, the expected number of months it takes to re-lease the property, required tenant improvements and the number of years the property will be held for investment. The use of alternative assumptions in the future cash flow analysis could result in a different determination of the property’s future cash flows and a different conclusion regarding the existence of an impairment, the extent of such loss, if any, as well as the carrying value of the real estate and related assets.
	Real Estate Escrow Deposits
	Real estate escrow deposits include funds held by escrow agents and others to be applied towards the purchase of real estate, which are included in other assets in the accompanying consolidated balance sheets.
	Fair Value
	Accounting Standards Codification, or ASC, 820, Fair Value Measurements and Disclosures, or ASC 820, defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands disclosures about fair value measurements. ASC 820 emphasizes that fair value is intended to be a market-based measurement, as opposed to a transaction-specific measurement.
	Fair value is defined by ASC 820 as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate the fair value. Assets and liabilities are measured using inputs from three levels of the fair value hierarchy, as follows:
	Level 1—Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
	Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data correlation or other means (market corroborated inputs).
	Level 3—Unobservable inputs, only used to the extent that observable inputs are not available, reflect the Company’s assumptions about the pricing of an asset or liability.
	The following describes the methods the Company used to estimate the fair value of the Company’s financial assets and liabilities:
	Cash and cash equivalents, restricted cash, tenant receivables, property escrow deposits, prepaid expenses, accounts payable and accrued liabilities—The Company considered the carrying values of these financial instruments, assets and liabilities, to approximate fair value because of the short period of time between origination of the instruments and their expected realization.
	Notes payable – Fixed Rate—The fair value is estimated by discounting the expected cash flows on notes payable at current rates at which management believes similar loans would be made considering the terms and conditions of the loan and prevailing market interest rates.
	Notes payable – Variable Rate—The carrying value of variable rate notes payable approximates fair value because they are interest rate adjustable.
	Notes receivables – The fair value is estimated by discounting the expected cash flows on the notes at interest rates at which management believes similar loans would be made.
	Contingent consideration liabilities—The fair value is estimated by using an income approach, which is determined based on the present value of probability-weighted future cash flows.
	Derivative instruments—The Company’s derivative instruments consist of interest rate swaps. These swaps are carried at fair value to comply with the provisions of ASC 820. The fair value of these instruments is determined using interest rate market pricing models. The Company incorporated credit valuation adjustments to appropriately reflect the Company’s nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Considerable judgement is necessary to develop estimated fair values of financial assets and liabilities. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize, or be liable for on disposition of the financial assets and liabilities.
	Revenue Recognition, Tenant Receivables and Allowance for Uncollectible Accounts
	The Company recognizes revenue in accordance with ASC 605, Revenue Recognition, or ASC 605. ASC 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed and determinable; and (4) collectability is reasonably assured.
	In accordance with ASC 840, Leases, minimum rental revenue is recognized on a straight-line basis over the term of the related lease (including rent holidays). Differences between rental income recognized and amounts contractually due under the lease agreements are credited or charged to deferred rent receivable or deferred rent liability, as applicable. Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses, is recognized as revenue in the period in which the related expenses are incurred. Tenant reimbursements are recognized and presented in accordance with ASC Subtopic 605-45, Revenue Recognition—Principal Agent Consideration, or ASC 605-45. ASC 605-45 requires that these reimbursements be recorded on a gross basis, when the Company is the primary obligor with respect to purchasing goods and services from third-party suppliers and has discretion in selecting the supplier and has credit risk.
	Tenant receivables and unbilled deferred rent receivables are carried net of the allowances for uncollectible amounts. An allowance will be maintained for estimated losses resulting from the inability of certain tenants to meet the contractual obligations under their lease agreements. The Company also maintains an allowance for deferred rent receivables arising from the straight-lining of rents. The Company’s determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s financial condition, security deposits, letters of credit, lease guarantees and current economic conditions and other relevant factors. As of December 31, 2014, the Company did not have an allowance for uncollectible tenant receivables.
	Income Taxes
	The Company currently qualifies and is taxed as a REIT under Sections 856 through 860 of the Code. As a REIT, the Company is required to distribute at least 90% of its taxable income (computed without regard to the dividends paid deduction and excluding capital gains) to its stockholders. In addition, the Company generally is not subject to federal corporate income taxes to the extent it distributes its taxable income to its stockholders. Even if the Company maintains its qualification for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and federal income and excise taxes on its undistributed income.
	Concentration of Credit Risk and Significant Leases
	As of December 31, 2014, the Company had cash on deposit, including restricted cash, in several financial institutions, all of which had deposits in excess of current federally insured levels totaling $124.4 million; however, the Company has not experienced any losses in such accounts. The Company limits its cash investments to financial institutions with high credit standing; therefore, the Company believes it is not exposed to any significant credit risk on its cash deposits. To date, the Company has experienced no loss or lack of access to cash in its accounts. Concentration of credit risk with respect to accounts receivable from tenants is limited.
	As of December 31, 2014, the Company owned real estate investments in 33 MSAs, (including two real estate investments owned through consolidated partnerships), two of which accounted for 10.0% or more of rental revenue. Real estate investments located in the Dallas-Ft. Worth-Arlington, Texas MSA and in the Chicago-Naperville-Elgin, Illinois-Indiana-Wisconsin MSA accounted for an aggregate of 17.2% and 10.0%, respectively, of rental revenue for the year ended December 31, 2014. As of December 31, 2013, the Company owned real estate investments in 24 MSAs, three of which accounted for 10.0% or more of rental revenue. Real estate investments located in the Dallas-Ft. Worth-Arlington, Texas MSA, Atlanta-Sandy Springs-Marietta, Georgia MSA and in the Philadelphia-Camden-Wilmington, Pennsylvania MSA accounted for an aggregate of 24.3%,  18.3% and 11.4%, respectively, of rental revenue for the year ended December 31, 2013. As of December 31, 2012, the Company owned real estate investments in 11 MSAs, two of which accounted for 10.0% or more of rental revenue. Real estate investments located in the Dallas-Ft. Worth-Arlington, Texas MSA and Atlanta-Sandy Springs-Marietta, Georgia MSA accounted for an aggregate of 29.7% and 47.4%, respectively, of rental revenue for the year ended December 31, 2012.
	For the year ended December 31, 2014, the Company’s two reportable business segments, data centers and healthcare, accounted for 56.3% and 43.7%, respectively, of rental revenue. For the year ended December 31, 2013, the Company’s two commercial real estate reportable business segments, data centers and healthcare, accounted for 57.9% and 42.1%, respectively, of rental revenue. For the year ended December 31, 2012, the Company’s two reportable business segments, data centers and healthcare, accounted for 78.8% and 21.2%, respectively, of rental revenue.
As of December 31, 2014, the Company had one tenant that accounted for 10.0% or more of rental revenue. The leases with AT&T Services, Inc. accounted for 18.5% of rental revenue for the year ended December 31, 2014. As of December 31, 2013, the Company had two tenants that accounted for 10.0% or more of rental revenue. The leases with Level 3 Communications, LLC and the Vanguard Group, Inc. accounted for 10.6% and 11.4%, respectively, of rental revenue for the year ended December 31, 2013. As of December 31, 2012, the Company had two tenants that accounted for 10.0% or more of rental revenue. The leases with Level 3 Communications, LLC and with Catholic Health Initiatives accounted for 26.8% and 16.1%, respectively, of rental revenue for the year ended December 31, 2012.
Stock-based Compensation
The Company accounts for stock-based compensation based upon the estimated fair value of the share awards. Accounting for stock-based compensation requires the fair value of the share awards to be amortized as compensation expense over the period for which the services relate and requires any dividend equivalents earned to be treated as dividends for financial reporting purposes. See Note 10—“Stock-based Compensation” for a further discussion of stock-based compensation awards.
Stockholders’ Equity
As of December 31, 2014, the Company was authorized to issue 350,000,000 shares of stock, of which 300,000,000 shares are designated as common stock at $0.01 par value per share and 50,000,000 shares are designated as preferred stock at $0.01 par value per share. As of December 31, 2014, the Company had approximately 175,562,000 shares of common stock issued and 175,038,000 shares of common stock outstanding, and no shares of preferred stock issued and outstanding. As of December 31, 2013, the Company had approximately 73,238,000 shares of common stock issued and 73,138,000 shares of common stock outstanding, and no shares of preferred stock issued and outstanding. The Company’s board of directors may authorize additional shares of capital stock and amend their terms without obtaining stockholder approval.
Share Repurchase Program
The Company approved a share repurchase program that allows for repurchases of shares of the Company’s common stock when certain criteria are met. The share repurchase program provides that all redemptions during any calendar year, including those upon death or a qualifying disability of a stockholder, are limited to those that can be funded with proceeds raised from the DRIP and the Second DRIP.
Repurchases of shares of the Company’s common stock are at the sole discretion of the Company’s board of directors. In addition, the Company’s board of directors, at its sole discretion, may amend, suspend, reduce, terminate or otherwise change the share repurchase program upon 30 days prior notice to the Company’s stockholders for any reason it deems appropriate. During the year ended December 31, 2014, the Company received valid redemption requests related to approximately 423,000 shares of common stock, all of which were redeemed in full for an aggregate purchase price of approximately $4,087,000 (an average of $9.66 per share).  During the year ended December 31, 2013, the Company received valid redemption requests related to approximately 80,000 shares of common stock, all of which were redeemed in full for an aggregate purchase price of approximately $783,000 (an average of $9.79 per share).
Distribution Policy and Distributions Payable
In order to maintain its status as a REIT, the Company is required to make distributions each taxable year equal to at least 90% of its taxable income, computed without regard to the dividends paid deduction and excluding capital gains. To the extent funds are available, the Company intends to continue to pay regular distributions to stockholders. Distributions are paid to stockholders of record as of the applicable record dates. As of December 31, 2014, the Company had aggregate distributions, since inception, of approximately $127,194,000 ($61,617,000 in cash and $65,577,000 of which were reinvested in shares of common stock pursuant to the DRIP and the Second DRIP), calculated at the current rate of 7.0%. The Company’s distributions declared per common share were $0.70, for the years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, the Company had distributions payable of approximately $10,409,000. Of those payable distributions, $4,711,000 of which were paid in cash and $5,698,000 of which were reinvested in shares of common stock pursuant to the Second DRIP on January 2, 2015.
Earnings Per Share
Basic earnings (loss) per share attributable for all periods presented are computed by dividing net income (loss) attributable to the Company by the weighted average number of shares of common stock outstanding during the period. Shares of non-vested restricted common stock give rise to potentially dilutive shares of common stock. Diluted earnings (loss) per share are computed based on the weighted average number of shares outstanding and all potentially dilutive securities. For the years ended December 31, 2014 and 2013, diluted earnings per share reflect the effect of approximately 18,000 shares and 17,000 shares, respectively, of non-vested shares of restricted common stock that were outstanding as of such period. For the year ended December 31, 2012, diluted earnings per share reflect the effect of 20,250 shares of non-vested shares of restricted common stock outstanding, but such shares were excluded from the computation of diluted earnings per share because such shares were antidilutive during the period.
Reportable Segments
ASC 280, Segment Reporting, establishes standards for reporting financial and descriptive information about an enterprise’s reportable segments. As disclosed previously, as of December 31, 2014, the Company operated through two reportable business segments – commercial real estate investments in data centers and healthcare. With the continued expansion of the Company’s portfolio, segregation of the Company’s operations into two reporting segments is useful in assessing the performance of the Company’s business in the same way that management reviews performance and makes operating decisions. See Note 15—“Segment Reporting” for further discussion on the reportable segments of the Company.
Derivative Instruments and Hedging Activities
As required by ASC 815, Derivatives and Hedging, or ASC 815, the Company records all derivative instruments as assets and liabilities in the statement of financial position at fair value. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in the consolidated statements of comprehensive income (loss) during the current period.
The Company is exposed to variability in expected future cash flows that are attributable to interest rate changes in the normal course of business. The Company’s primary strategy in entering into derivative contracts is to add stability to future cash flows by managing its exposure to interest rate movements.  The Company utilizes derivative instruments, including interest rate swaps, to effectively convert some its variable rate debt to fixed rate debt. The Company does not enter into derivative instruments for speculative purposes.
In accordance with ASC 815, the Company designates interest rate swap contracts as cash flow hedges of floating-rate borrowings. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) in the consolidated statements of comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction and the same period during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in the consolidated statements of comprehensive income (loss) during the current period.
In accordance with the fair value measurement guidance Accounting Standards Update, or ASU, 2011-04, Fair Value Measurement, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Recently Issued Accounting Pronouncements
In April 2014, the Financial Accounting Standards Board, or the FASB, issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, or ASU 2014-08. ASU 2014-08 changes the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the company’s operations and financial results. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. The adoption of ASU 2014-08 is effective prospectively for reporting periods beginning on or after December 15, 2014. The Company does not expect the adoption of ASU 2014-08 to have a material effect on the Company’s consolidated financial statements.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. The objective of ASU 2014-09 is to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle, which may require more judgment and estimates within the revenue recognition process than are required under existing GAAP. The adoption of ASU 2014-09 is effective retrospectively for reporting periods beginning after December 15, 2016. Early adoption of ASU 2014-09 is not permitted. The Company is in the process of evaluating the impact ASU 2014-09 will have on the Company’s consolidated financial statements.
In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About An Entity’s Ability to Continue As a Going Concern, or ASU 2014-15, which describes how an entity should assess its ability to meet obligations and sets rules for how this information should be disclosed in the financial statements. The adoption of ASU 2014-15 is effective for reporting periods ending after December 15, 2016, early adoption is permitted. The Company is in the process of evaluating the impact ASU 2014-15 will have on the Company’s consolidated financial statements.
On January 9, 2015, the FASB issued ASU 2015-01, Income Statement-Extraordinary and Unusual Items, or ASU 2015-01, to simplify income statement classification by removing the concept of extraordinary items from GAAP. As a result, items that are both unusual and infrequent will no longer be separately reported net of tax after continuing operations. The standard is effective for periods beginning after December 15, 2015. The Company does not expect the adoption of ASU 2015-01 to have a material effect on the Company’s consolidated financial statements.
Reclassifications
Certain prior period amounts have been reclassified to conform to the current financial statement presentation, with no effect on the Company’s consolidated financial position or results of operations.

	The Company reimburses the Advisor, or its affiliates, for acquisition expenses related to selecting, evaluating, acquiring and investing in properties. The reimbursement of acquisition expenses, acquisition fees and real estate commissions and other fees paid will not exceed, in the aggregate, 6.0% of the contract purchase price or total development costs of certain acquisitions, unless fees in excess of such limits are approved by a majority of the Company’s independent directors. For the years ended December 31, 2014, 2013 and 2012, acquisition fees and acquisition related costs totaled $24,250,000, $13,104,000 and $11,474,000, respectively, which did not exceed 6.0% of the purchase price of the Company’s acquisitions during such periods. Acquisition fees and expenses in connection with the acquisition of properties determined to be business combinations are expensed as incurred, including investment transactions that are no longer under consideration, and are included in acquisition related expenses in the accompanying consolidated statements of comprehensive income (loss). Acquisition fees and expenses associated with transactions determined to be an asset purchase are capitalized. The Company expensed acquisition fees and expenses for the years ended December 31, 2014, 2013 and 2012 of approximately $10,653,000, $5,615,000 and $11,474,000, respectively.

	(3)In connection with the acquisition of three real estate investments, the Company obtained financing of $239,850,000, with the remaining balance of the purchase price paid using cash proceeds from the Offering.
	Consolidated Partnerships
	Bay Area Regional Medical Center
	On July 11, 2014, the Company, through a wholly-owned consolidated subsidiary of the Operating Partnership, completed the acquisition of a healthcare property, or the Bay Area Regional Medical Center, located in Webster, Texas, for the purchase price of $198,000,000, plus closing costs. The acquisition of the Bay Area Regional Medical Center was funded by a $100,000,000 loan, by a $39,900,000 equity investment from an unaffiliated investor, or Bay Area Real Estate, in exchange for a 40% ownership interest and by a $73,847,000 equity investment by the Operating Partnership for a 60% ownership interest. The Operating Partnership funded its investment with net proceeds from the Offering.
	On July 7, 2014, the Operating Partnership entered into a limited liability agreement, or the Agreement, with Bay Area Real Estate. The material terms of the Agreement provide for the following: (a) the Operating Partnership will serve as the manager of the partnership and will have exclusive and complete responsibility for the operations and management of the partnership; provided, however, that the investor has approval rights over certain major decisions; (b) the Operating Partnership, through its wholly-owned subsidiary, and the investor will be entitled to a property management fee equal to 3% of their pro rata share of the net rental revenues from the property; (c) earnings are allocated to the Operating Partnership and the unaffiliated investor in proportion to their respective ownership interest; (d) upon the request of the tenant, the Operating Partnership will contribute up to an additional $35,000,000 related to the build out of the property and upon the receipt of additional funding the ownership interest in partnership will be adjusted proportionally to each partner’s investment and (e) the investor may sell its ownership interest and the Operating Partnership has the right (but not obligation) to first purchase the investor’s interest at the purchase price, based on the price of percentage of ownership interest.
	180 Peachtree Data Center
	Consolidated Variable Interest Entity
	On January 3, 2012, an indirect partially-owned subsidiary of the Operating Partnership purchased the 180 Peachtree Data Center through a consolidated partnership with three unaffiliated institutional investors. The Operating Partnership owns approximately 20.53% and the institutional investors own an aggregate of 79.47% of the consolidated partnership’s interests. Upon acquisition, the Company recorded the fair value of noncontrolling interest at $34,406,000.
	The Company concluded that the entity that owns the 180 Peachtree Data Center is a VIE as the entity had insufficient equity to finance its activities without additional subordinated financial support. As the Company has the power to direct the activities that most significantly impact the entity, it is the primary beneficiary of and therefore has consolidated the entity, which owns the 180 Peachtree Data Center. Any significant amounts of assets and liabilities related to the consolidated VIE are identified parenthetically on the accompanying consolidated balance sheets. For the year ended December 31, 2014, total revenue and net income related to the 180 Peachtree Data Center were $17,493,000 and $3,432,000, respectively.  For the year ended December 31, 2013, total revenue and net income related to the 180 Peachtree Data Center were $16,136,000 and $2,945,000, respectively. For the year ended December 31, 2014, cash flows related to the 180 Peachtree Data Center consisted of $4,928,000 in cash provided by operating activities,  $226,000 in cash used in investing activities and $3,716,000 in cash used in financing activities. For the year ended December 31, 2013, cash flows related to the 180 Peachtree Data Center consisted of $4,440,000 in cash provided by operating activities, $350,000 in cash used in investing activities and $4,142,000 in cash used in financing activities. The creditors of the consolidated VIE do not have recourse to the Company’s general credit.

Credit Facility [Abstract]
Credit Facility	Note 9—Credit Facility
	On May 28, 2014, the Operating Partnership amended certain agreements related to the KeyBank Credit Facility to include American Momentum Bank, RBS Citizens, N.A., and United Community Bank as lenders and to increase the maximum commitments available under the KeyBank Credit Facility from $225,000,000 to an aggregate of up to $365,000,000, consisting of a $290,000,000 revolving line of credit, with a maturity date of May 28, 2017, subject to the Operating Partnership’s right to a 12-month extension, and $75,000,000 in term loans, with a maturity date of May 28, 2018, subject to the Operating Partnership’s right to a 12-month extension. The new and existing lenders agreed to make the loans on an unsecured basis (previously all loans were secured by a perfected first priority lien and security interest on the mortgaged properties). The proceeds of loans made under the KeyBank Credit Facility may be used to finance the acquisition of real estate investments, capital expenditures with respect to real estate and for general corporate working capital purposes. The KeyBank Credit Facility can be increased to $500,000,000 under certain circumstances.
	In connection with the amendment to the KeyBank Credit Facility, the annual interest rate payable under the KeyBank Credit Facility was decreased to, at the Operating Partnership’s option, either (a) LIBOR, plus an applicable margin ranging from 1.75% to 2.25% (the margin rate was previously set at a range from 2.25% to 3.00%), which is determined based on the overall leverage of the Operating Partnership; or (b) a base rate, which means, for any day, a fluctuating rate per annum equal to the prime rate for such day, plus an applicable margin ranging from 0.75% to 1.25% (the margin rate was previously set at a range from 1.00% to 1.75%), which is determined based on the overall leverage of the Operating Partnership. Additionally, the requirement to pay a fee on the unused portion of the lenders’ commitments under the KeyBank Credit Facility was reduced from 0.30% per annum to 0.25% per annum if the average daily amount outstanding balance under the KeyBank Credit Facility is less than 50% of the lenders’ commitments, and from 0.20% per annum to 0.15% per annum if the average daily amount outstanding under the KeyBank Credit Facility is greater than 50% of the lenders’ commitments. The unused fee is payable quarterly in arrears.
	In connection with the KeyBank Credit Facility, the Operating Partnership entered into interest swap agreements with KeyBank National Association to effectively fix LIBOR on $55,000,000 out of $75,000,000 of the term loans. The weighted average rate of the fixed portion of the term loans of the KeyBank Credit Facility was 0.91%, resulting in an interest rate ranging from 2.66% to 3.16% per annum. The revolving line of credit and the term loans can be prepaid prior to maturity without penalty; provided, however, that any portion of the term loans that is prepaid may not be reborrowed, and the Operating Partnership may be subject to a breakage fee under the swap agreements, if applicable.
	The KeyBank Credit Facility agreement contains various affirmative and negative covenants that are customary for credit facilities and transactions of this type, including limitations on the incurrence of debt and limitations on distributions by the properties that are included in the unencumbered pool for the KeyBank Credit Facility in the event of a default. The KeyBank Credit Facility agreement also imposes the following financial covenants: (i) a maximum property value requirement; (ii) a maximum ratio of liabilities to asset value; (iii) a maximum daily distribution covenant; (iv) a minimum number of unencumbered pool properties in the unencumbered pool; (v) a minimum consolidated net worth; and (vi) a minimum unencumbered pool actual debt service coverage ratio. In addition, the KeyBank Credit Facility agreement includes events of default that are customary for credit facilities and transactions of this type. We believe we were in compliance with all financial covenant requirements at December 31, 2014.
	The actual amount of credit available under the KeyBank Credit Facility is a function of certain loan-to-cost, loan-to-value, debt yield and debt service coverage ratios. The credit available to the Operating Partnership under the KeyBank Credit Facility will be a maximum principal amount of the value of the assets that are included in the unencumbered pool. During the year ended December 31, 2014, the Company paid down $97,000,000 under the KeyBank Credit Facility. As of December 31, 2014, the total unencumbered pool availability under the KeyBank Credit Facility was $365,000,000. As of December 31, 2014, the Company had an outstanding balance of $75,000,000 under the KeyBank Credit Facility and had an aggregate unencumbered pool availability of $290,000,000.

Stock-based Compensation [Abstract]
Stock-based Compensation	Note 10—Stock-based Compensation
	The Company’s  2010 Restricted Share Plan, or the 2010 Plan, pursuant to which the Company has the authority to grant restricted and deferred stock awards to persons eligible under the 2010 Plan. The Company authorized and reserved 300,000 shares of its common stock for issuance under the 2010 Plan, subject to certain adjustments. Subject to certain limited exceptions, restricted stock may not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of and is subject to forfeiture within the vesting period. Restricted stock awards generally vest ratably over four years. The Company uses the straight-line method to recognize expenses for service awards with graded vesting. Restricted stock awards are entitled to receive dividends during the vesting period. In addition to the ratable amortization of fair value over the vesting period, dividends paid on unvested shares of restricted stock, which are not expected to vest, are charged to compensation expense in the period paid.
	On June 27, 2014, the Company awarded an aggregate of 9,000 shares of restricted stock to its independent board members in connection with their re-election to the board of directors of the Company. The fair value of each share of restricted common stock that has been granted under the 2010 Plan is estimated at the date of grant at $10.00 per share, the per share price of shares sold in the Offering. The restricted stock awards vest over a period of four years. The awards are amortized using the straight-line method over four years.
	As of December 31, 2014 and 2013,  there was $178,000 and $182,000, respectively, of total unrecognized compensation expense related to nonvested shares of our restricted common stock. This expense is expected to be recognized over a remaining weighted average period of 1.69 years. This expected expense does not include the impact of any future stock-based compensation awards.
	As of December 31, 2014 and 2013, the fair value of the nonvested shares of restricted common stock was $240,000 and $232,500, respectively. A summary of the status of the nonvested shares of restricted common stock as of December 31, 2013 and the changes for the year ended December 31, 2014 is presented below:
			Weighted Average Grant Date

	Certain affiliates of the Company received fees and compensation in connection with the Offering and will continue to receive fees during the acquisition, management and sale of the assets of the Company. SC Distributors, LLC, or the Dealer Manager, received a selling commission of up to 7.0% of gross offering proceeds. In addition, the Dealer Manager received up to 2.75% of gross offering proceeds as a dealer manager fee. The Dealer Manager, in its sole discretion, re-allowed all or a portion of its dealer manager fee to participating broker-dealers as a marketing and due diligence expense reimbursement. The Company paid the Dealer Manager approximately $90,665,000,  $47,499,000 and $15,538,000 for the years ended December 31, 2014, 2013 and 2012, respectively, for selling commissions and dealer manager fees in connection with the Offering. On June 6, 2014, the Offering terminated.
	Organization and offering expenses were paid by the Advisor, or its affiliates, on behalf of the Company. The Advisor was reimbursed for actual expenses incurred up to 15.0% of the gross offering proceeds (including selling commissions and the dealer manager fee from the sale of shares of the Company’s common stock in the Offering, other than shares of common stock sold pursuant to the DRIP and the Second DRIP). For the years ended December 31, 2014, 2013 and 2012, the Company reimbursed $1,135,000,  $9,654,000 and $2,999,000, respectively, in offering expenses to the Advisor, or its affiliates.

	The Company pays the Advisor, or its affiliates, an acquisition and advisory fee in the amount of 2.0% of the contract purchase price of each asset or loan the Company acquires or originates. In addition, the Company reimburses the Advisor for all acquisition expenses it incurs on the Company’s behalf, but only to the extent the total amount of all acquisition fees and acquisition expenses is limited to 6.0% of the contract purchase price. For the years ended December 31, 2014, 2013 and 2012, the Company incurred $19,818,000,  $10,822,000 and $5,835,000, respectively, in acquisition fees to the Advisor, or its affiliates, related to investments in real estate. During the years ended December 31, 2014, 2013 and 2012, the Company paid $351,000,  $1,016,000 and $0, respectively, in advisory fees to the Advisor, or its affiliates, related to investments in real estate-related notes receivables.
	The Company pays the Advisor an annual asset management fee. On November 25, 2014, pursuant to an amendment to the advisory agreement, the annual asset management fee was reduced from 1.0% to 0.85% of the aggregate asset value plus costs and expenses incurred by the Advisor in providing asset management services and the monthly asset management fee was reduced from 0.08333% to 0.07083% of the aggregate asset value as of the last day of the immediately preceding month. For the years ended December 31, 2014, 2013 and 2012, the Advisor recognized $13,682,000,  $4,682,000 and $1,245,000, respectively, in gross asset management fees.

	The Company reimburses the Advisor for all expenses it paid or incurred in connection with the services provided to the Company, subject to certain limitations. The Company will not reimburse the Advisor for personnel costs in connection with services for which the Advisor receives an acquisition and advisory fee or a disposition fee. For the years ended December 31, 2014, 2013 and 2012, the Advisor allocated $1,599,000,  $1,005,000 and $662,000, respectively, in operating expenses on the Company’s behalf.

	The Company has no direct employees. The employees of the Advisor and other affiliates provide services to the Company related to acquisitions, property management, asset management, accounting, investor relations, and all other administrative services. If the Advisor, or its affiliates, provides a substantial amount of services, as determined by a majority of the Company’s independent directors, in connection with the sale of one or more properties, the Company will pay the Advisor a disposition fee. On November 25, 2014, pursuant to an amendment to the advisory agreement, the disposition fee was reduced up to the lesser of 1.0%, from the previous 2.0%, of the contract sales price and one-half of the brokerage commission paid if a third party broker is involved. In no event will the combined real estate commission paid to the Advisor, its affiliates and unaffiliated third parties exceed 6.0% of the contract sales price. In addition, after investors have received a return on their net capital contributions and an 8.0% cumulative non-compounded annual return, then the Advisor is entitled to receive 15.0% of the remaining net sale proceeds. As of December 31, 2014, the Company did not incur a disposition fee or a subordinated sale fee to the Advisor or its affiliates.
	Upon listing of the Company’s common stock on a national securities exchange, a listing fee equal to 15.0% of the amount by which the market value of the Company’s outstanding stock plus all distributions paid by the Company prior to listing exceeds the sum of the total amount of capital raised from investors and the amount of cash flow necessary to generate an 8.0% cumulative, non-compounded annual return to investors will be paid to the Advisor. As of December 31, 2014, the Company did not incur a listing fee.
	The Company pays Carter Validus Real Estate Management Services, LLC, or the Property Manager, leasing and management fees for the Company’s properties. Such fees equal 3.0% of gross revenues from single-tenant properties and 4.0% of gross revenues from multi-tenant properties. The Company will reimburse the Property Manager and its affiliates for property-level expenses that any of them pay or incur on the Company’s behalf, including salaries, bonuses and benefits of persons employed by the Property Manager and its affiliates, except for the salaries, bonuses and benefits of persons who also serve as one of the Company’s executive officers. The Property Manager and its affiliates may subcontract the performance of their duties to third parties and pay all or a portion of the property management fee to the third parties with whom they contract for these services. If the Company contracts directly with third parties for such services at customary market fees, the Company will pay the Property Manager an oversight fee equal to 1.0% of the gross revenues of the property managed. In no event will the Company pay the Property Manager, the Advisor, or its affiliates, both a property management fee and an oversight fee with respect to any particular property. The Company may pay the Property Manager a separate fee for the one-time initial rent-up, lease renewals or leasing-up of newly constructed properties in an amount not to exceed the fee customarily charged in arm’s length transactions by others rendering similar services in the same geographic area for similar properties as determined by a survey of brokers and agents in such area. For the years ended December 31, 2014, 2013 and 2012, the Company incurred $4,815,000,  $1,470,000 and $561,000, respectively, in property management fees to the Property Manager.

Business Combinations [Abstract]
Business Combinations	Note 14—Business Combinations
	During the year ended December 31, 2014, the Company completed the acquisition of 100% fee simple interest in eight real estate investments (four data centers and four healthcare) that were determined to be business combinations, comprised of ten buildings. The aggregate purchase price of the acquisitions determined to be business combinations was $470,786,000, plus closing costs, including $6,230,000 in contingent consideration.

Segment Reporting [Abstract]
Segment Reporting	Note 15—Segment Reporting
	The Company aggregates commercial real estate investments in data centers and healthcare into two operating segments for reporting purposes. The Company’s commercial real estate investments in data centers and healthcare are based on certain underwriting assumptions and operating criteria, which are different for data centers and healthcare. Management reviews the performance and makes operating decisions based on these two reportable segments. There were no intersegment sales or transfers as of December 31,  2014.
	The Company evaluates performance based on net operating income of the combined properties in each segment. Net operating income, a non-GAAP financial measure, is defined as total revenues, less rental expenses, which excludes depreciation and amortization, general and administrative expenses, acquisition related expenses, asset management fee, interest expense and interest income. The Company believes that segment net operating income serves as a useful supplement to net income (loss) because it allows investors and management to measure unlevered property-level operating results and to compare operating results to the operating results of other real estate companies and between periods on a consistent basis. Segment net operating income should not be considered as an alternative to net income (loss) determined in accordance with GAAP as an indicator of financial performance, and accordingly, the Company believes that in order to facilitate a clear understanding of the consolidated historical operating results, segment net operating income should be examined in conjunction with net income (loss) as presented in the accompanying consolidated financial statements and data included elsewhere in this Annual Report on Form 10-K.
	Real estate-related notes receivables interest income, general and administrative expenses, acquisition related expenses, change in fair value consideration, asset management fees, depreciation and amortization and interest expense are not allocated to individual segments for purposes of assessing segment performance.
	Non-segment assets primarily consist of corporate assets including cash and cash equivalents, real estate and escrow deposits, deferred financing costs, real estate-related notes receivables and other assets not attributable to individual properties.
	Summary information for the reportable segments during the years ended December 31, 2014, 2013 and 2012,  are as follows (amounts in thousands):

Fair Value [Abstract]
Fair Value	Note 16—Fair Value
	Notes payable – Fixed Rate— The estimated fair value of notes payable –  fixed rate measured using quoted prices and observable inputs from similar liabilities (Level 2) was approximately $134,837,000 and $139,142,000 as of December 31, 2014 and December 31, 2013, respectively, as compared to the carrying value of $134,271,000 and $137,049,000 as of December 31, 2014 and December 31, 2013, respectively.
	Notes payable – Variable— The estimated fair value of notes payable – variable rate fixed through interest rate swap agreements (Level 2) was approximately $208,889,000 and $62,835,000 as of December 31, 2014 and December 31, 2013, respectively, as compared to the carrying value of $206,162,000 and $64,128,000 as of December 31, 2014 and December 31, 2013, respectively. The carrying value of the notes payable – variable was $150,476,000 and $0 as of December 31, 2014 and December 31, 2013, respectively, which approximated its fair value.
	KeyBank Credit Facility—  The carrying value of the KeyBank Credit Facility – variable was $20,000,000 and $97,000,000, which approximated its fair value, as of December 31, 2014 and December 31, 2013, respectively. The estimated fair value of the KeyBank Credit Facility – variable rate fixed through interest rate swap agreements (Level 2) was approximately $50,505,000 and $51,922,000 as of December 31, 2014 and December 31, 2013, respectively, as compared to the carrying value of $55,000,000 and $55,000,000 as of December 31, 2014 and December 31, 2013, respectively.
	Real estate-related notes receivables — The estimated fair value of the real estate-related notes receivables was $23,421,000 and $58,176,000 as of December 31, 2014 and December 31, 2013, respectively, as compared to the carrying value of $23,535,000 and $54,080,000 as of December 31, 2014 and December 31, 2013, respectively. The fair value of the Company’s real estate-related notes receivables is estimated using significant unobservable inputs not based on market activity, but rather through particular valuation techniques (Level 3). The fair value was measured based on the income approach valuation methodology, which requires certain judgments to be made by management.
	Contingent consideration— The Company has contingent obligations to transfer cash payments to the former owner in conjunction with a certain acquisition if specified future operational objectives are met over future reporting periods. Liabilities for contingent consideration will be measured at fair value each reporting period, with the acquisition-date fair value included as part of the consideration transferred, and subsequent changes in fair value recorded in earnings as change in fair value of contingent consideration.
	The estimated fair value and the carrying value of the contingent consideration was $6,570,000 as of December 31, 2014, which is reported in the accompanying consolidated balance sheets in accounts payable and other liabilities. The Company uses an income approach to value the contingent consideration liability, which is determined based on the present value of probability-weighted future cash flows. The Company has classified the contingent consideration liability as Level 3 of the fair value hierarchy due to the lack of relevant observable market data over fair value inputs such as probability-weighting for payment outcomes. Increases in the assessed likelihood of a high payout under a contingent consideration arrangement contributes to increases in the fair value of the related liability. Conversely, decreases in the assessed likelihood of a higher payout under a contingent consideration arrangement contributes to decreases in the fair value of the related liability. Changes in assumptions could have an impact on the payout of contingent consideration arrangements with a maximum payout of $6,570,000 in cash and a minimum payout of $0 as of December 31, 2014.
	Derivative instruments— Considerable judgment is necessary to develop estimated fair values of financial instruments. Accordingly, the estimates presented herein are not necessarily indicative of the amount the Company could realize, or be liable for, on disposition of the financial instruments. The Company has determined that the majority of the inputs used to value its interest rate swaps fall within Level 2 of the fair value hierarchy. The credit valuation adjustment associated with these instruments utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and the respective counterparty. However, as of December 31, 2014, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions, and has determined that the credit valuation adjustments are not significant to the overall valuation of its interest rate swaps. As a result, the Company determined that its interest rate swaps valuation in its entirety is classified in Level 2 of the fair value hierarchy.
	In accordance with the fair value hierarchy described above, the following table shows the fair value of the Company’s financial assets and liabilities that are required to be measured at fair value on a recurring basis as of December 31, 2014 and December 31, 2013 (amounts in thousands):

Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities
	Note 17—Derivative Instruments and Hedging Activities
	Cash Flow Hedges of Interest Rate Risk
	The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed rate payments over the life of the agreements without exchange of the underlying notional amount.
	The effective portion of changes in the fair value of derivatives designated, and that qualify, as cash flow hedges is recorded in accumulated other comprehensive income (loss) in the accompanying consolidated statements of stockholders’ equity and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the year ended December 31, 2014, such derivatives were used to hedge the variable cash flows associated with variable rate debt. The ineffective portion of changes in fair value of the derivatives is recognized directly in earnings. During the years ended December 31, 2014 and 2013, no gains or losses were recognized due to ineffectiveness of hedges of interest rate risk.
	Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. During the next twelve months, the Company estimates that an additional $2,930,000 will be reclassified from accumulated other comprehensive income (loss) as an increase to interest expense.
	See Note 16—“Fair Value” for a further discussion of the fair value of the Company’s derivative instruments.
	The following table summarizes the notional amount and fair value of the Company’s derivative instruments (amounts in thousands):

	Accounting for changes in the fair value of a derivative instrument depends on the intended use and designation of the derivative instrument. The Company designated the interest rate swaps as cash flow hedges to hedge the variability of the anticipated cash flows on its variable rate notes payable. The change in fair value of the effective portion of the derivative instrument that is designated as a hedge is recorded in other comprehensive income (loss), or OCI, in the accompanying consolidated statements of comprehensive income (loss).
	The table below summarizes the amount of gains or losses recognized on interest rate derivatives designated as cash flow hedges, net of noncontrolling interest, for the years ended December 31, 2014 and 2013 (amounts in thousands):
			For the Year Ended
			December 31,
	Derivatives in Cash Flow Hedging Relationships (Interest Rate Swaps)		2014			2013
	Amount of (loss) income recognized in OCI on derivatives (effective portion)		$	-4,181		$	825
	Amounts reclassified from accumulated other
	comprehensive income (loss) (effective portion)		$	2,420		$	738
	Credit Risk-Related Contingent Features
	The Company has agreements with each of its derivative counterparties that contain cross-default provisions, whereby if the Company defaults on certain of its unsecured indebtedness, then the Company could also be declared in default on its derivative obligations, resulting in an acceleration of payment thereunder.
	In addition, the Company is exposed to credit risk in the event of non-performance by its derivative counterparties. The Company believes it mitigates its credit risk by entering into agreements with credit-worthy counterparties. The Company records credit risk valuation adjustments on its interest rate swaps based on the respective credit quality of the Company and the counterparty. As of December 31, 2014, the fair value of derivatives in a net liability position, including accrued interest but excluding any adjustment for nonperformance risk related to these agreements, was $1,764,000. As of December 31, 2014, there were no termination events or events of default related to the interest rate swaps.

Income Taxes [Abstract]
Income Taxes	Note 19—Income Taxes
	For federal income tax purposes, distributions to stockholders are characterized as either ordinary dividends, capital gain distributions, or nontaxable distributions. Nontaxable distributions will reduce U.S. stockholders’ basis in their shares. The following table shows the character of distributions the Company paid on a percentage basis during the years ended December 31, 2014, 2013 and 2012:
		For the Year Ended
		December 31,

	Nontaxable distributions	60.05%	38.52%	80.22%
	Total	100.00%	100.00%	100.00%
	The Company concluded there was no impact related to uncertain tax provisions from the results of the operations of the Company for the years ended December 31, 2014, 2013 and 2012. The Company’s policy is to recognize accrued interest related to unrecognized tax benefits as a component of interest expense and penalties related to unrecognized tax benefits as a component of general and administrative expenses. From inception through December 31, 2014, the Company had not recognized any interest expense or penalties related to unrecognized tax benefits. The United States of America is the major tax jurisdiction for the Company, and the earliest tax year subject to examination is 2011.

Summary of Significant Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation
	The accompanying consolidated financial statements include the accounts of the Company, the Operating Partnership, all majority-owned subsidiaries and controlled subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	In determining whether the Company has a controlling interest in the entities and the requirement to consolidate the accounts of any such entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the partners/members as well as whether the investment entity is a variable interest entity, or VIE, for which the Company is the primary beneficiary.
	A VIE is a legal entity in which the equity investors do not have the characteristics of a controlling financial interest but is subject to consolidation if the entity (i) has insufficient equity at risk to permit the entity to finance its activities, (ii) whose at risk equity owners, as a group, do not have the power to direct the activities that most significantly impact the entity’s economic performance, or (iii) whose at risk equity owners do not absorb the entity’s losses or receive its returns. The Company consolidates all VIEs for which it is the primary beneficiary. In determining whether the Company is the primary beneficiary of a VIE, it considers if it has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE. Consideration of various factors include, but are not limited to, the Company’s ability to direct the activities that most significantly impact the entity’s economic performance, its form of ownership interest, its representation on the entity’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and to replace the manager of and/or liquidate the entity.
	As of December 31, 2014, the Company consolidated the accounts of one VIE, the 180 Peachtree Data Center, as the Company has the power to direct the activities that most significantly impact the entity’s economic performance, see Note 3—“Real Estate Investments.”
	In addition, the Company evaluates its loan investments to determine if the borrowing entity qualifies as a VIE. As of December 31, 2014, the Company determined that two of its loan investments in real estate-related notes receivables were with entities that qualify as VIEs, of which the Company is not the primary beneficiary because it does not have the ability to direct the activities of the VIEs that most significantly impact the entities’ economic performance. See Note 6—“Real Estate-Related Notes Receivables.”
Real Estate-Related Notes Receivables	Real Estate-Related Notes Receivables
	Real estate-related notes receivables are recorded at stated principal amounts net of any discount or premium and deferred loan origination costs or fees. The related discounts or premiums are accreted or amortized over the life of the real estate-related notes receivables, as applicable. The Company defers certain loan origination and commitment fees and amortizes them as an adjustment of yield over the term of the real estate-related note receivable. The related accretion of discounts and/or amortization of premiums and origination costs are recorded in real estate-related notes receivables interest income in the accompanying consolidated statements of comprehensive income (loss).
	The Company evaluates the collectability of both interest and principal on each real estate-related note receivable, primarily through the evaluation of credit quality indicators such as underlying collateral and payment history. The Company does not intend to sell its investments in real estate-related notes receivables and it is not likely that the Company will be required to sell its investments in real estate-related notes receivables before recovery of their amortized costs basis, which may be at maturity. There were no amounts past due on real estate-related notes receivables as of December 31, 2014. A real estate-related note receivable is considered to be impaired, when based upon current information and events, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. If a real estate-related note receivable is considered to be impaired, the amount of loss is calculated by comparing the recorded investment to the value determined by discounting the expected future cash flows at the real estate-related note receivable’s effective interest rate or to the value of the underlying collateral if the real estate-related note receivable is collateral dependent. Interest income on performing real estate-related notes receivables is accrued as earned. Interest income on an impaired real estate-related note receivable is recognized on a cash basis. Evaluating a real estate-related note receivable for potential impairment can require management to exercise significant judgments. No impairment losses were recorded related to investments in real estate-related notes receivables for the years ended December 31, 2014, 2013 and 2012. In addition, no allowances for uncollectability were recorded related to investments in real estate-related notes receivables as of December 31, 2014 and December 31, 2013.
Use of Estimates	Use of Estimates
	The preparation of the consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value.
Restricted Cash Held in Escrow	Restricted Cash Held in Escrow
	Restricted cash held in escrow includes cash held by lenders in escrow accounts for tenant and capital improvements, repairs and maintenance and other lender reserves for certain properties, in accordance with the respective lender’s loan agreement. Contributions and receipts of escrowed funds have been classified as financing activities since such funds are controlled by lenders and serve as collateral for the notes payable. Restricted cash is reported in other assets in the accompanying consolidated balance sheets. See Note 5—“Other Assets.”
Deferred Financing Costs	Deferred Financing Costs
	Deferred financing costs are loan fees, legal fees and other third-party costs associated with obtaining financing. These costs are amortized over the terms of the respective financing agreements using the effective interest method. Unamortized deferred financing costs are generally expensed when the associated debt is refinanced or repaid before maturity unless specific rules are met that would allow for the carryover of such costs to the refinanced debt. Costs incurred in seeking financing transactions that do not close are expensed in the period in which it is determined that the financing will not close. Deferred financing costs are reported in other assets in the accompanying consolidated balance sheets. See Note 5—“Other Assets.”
Investment in Real Estate	Investment in Real Estate
	Real estate costs related to the acquisition, development, construction and improvement of properties are capitalized. Repair and maintenance costs are expensed as incurred and significant replacements and betterments are capitalized. Repair and maintenance costs include all costs that do not extend the useful life of the real estate asset. The Company considers the period of future benefit of an asset in determining the appropriate useful life. Real estate assets, other than land, are depreciated or amortized on a straight-line basis over each asset’s useful life. The Company estimated the useful lives of its assets by class as follows:
	Building and improvements	15 – 40 years
	Tenant improvements	Shorter of lease term or expected useful life
	Identified intangible assets	Remaining term of related lease
	Furniture, fixtures, and equipment	3 – 10 years
Allocation of Purchase Price of Real Estate	Allocation of Purchase Price of Real Estate
	Upon the acquisition of real properties, the Company evaluates whether the acquisition is a business combination or an asset acquisition. The Company determined that properties acquired with an existing lease in place are accounted as a business combination and properties acquired without an existing lease in place are accounted as an asset acquisition.
	Business Combinations
	Upon the acquisition of real properties determined to be business combinations, the Company allocates the purchase price of such properties to acquired tangible assets, consisting of land and buildings, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases and the value of in-place leases, based in each case on their estimated fair values.
	The fair values of the tangible assets of an acquired property (which includes the land and buildings and improvements) are determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and buildings and improvements based on management’s determination of the relative fair value of these assets. Management determines the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases, including leasing commissions and other related costs. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses during the expected lease-up periods based on current market conditions.
	The fair values of above-market and below-market in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease including any fixed rate bargain renewal periods, with respect to a below-market lease. The above-market and below-market lease values are capitalized as intangible lease assets or liabilities. Above-market lease values are amortized as an adjustment of rental income over the remaining terms of the respective leases. Below-market leases are amortized as an adjustment of rental income over the remaining terms of the respective leases, including any fixed rate bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above-market and below-market in-place lease values related to that lease would be recorded as an adjustment to rental income.
	The fair values of in-place leases include an estimate of direct costs associated with obtaining a new tenant and opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant include commissions, tenant improvements, and other direct costs and are estimated based on management’s consideration of current market costs to execute a similar lease. The value of opportunity costs is calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. The in-place lease intangibles are included in real estate assets in the accompanying consolidated balance sheets and amortized to expense over the remaining terms of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.
	Asset Acquisitions
	Upon the acquisition of real estate properties determined to be asset acquisitions, the Company allocates the purchase price of such properties generally to acquired tangible assets, consisting of land and buildings and improvements, based in each case on initial cost of the asset acquired.
Acquisition Fees and Expenses	Acquisition Fees and Expenses
	Acquisition fees and expenses in connection with the acquisition of properties determined to be business combinations are expensed as incurred, including investment transactions that are no longer under consideration, and are included in acquisition related expenses in the accompanying consolidated statements of comprehensive income (loss). Acquisition fees and expenses associated with transactions determined to be an asset acquisitions are capitalized.
Impairment of Long Lived Assets	Impairment of Long Lived Assets
	The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of its real estate and related intangible assets may not be recoverable. When indicators of potential impairment suggest that the carrying value of real estate and related intangible assets may not be recoverable, the Company assesses the recoverability of the assets by estimating whether the Company will recover the carrying value of the asset through its undiscounted future cash flows and its eventual disposition. If based on this analysis the Company does not believe that it will be able to recover the carrying value of the asset, the Company will record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the asset. No impairment losses have been recorded to date.
	When developing estimates of expected future cash flows, the Company makes certain assumptions regarding future market rental income amounts subsequent to the expiration of current lease arrangements, property operating expenses, terminal capitalization and discount rates, the expected number of months it takes to re-lease the property, required tenant improvements and the number of years the property will be held for investment. The use of alternative assumptions in the future cash flow analysis could result in a different determination of the property’s future cash flows and a different conclusion regarding the existence of an impairment, the extent of such loss, if any, as well as the carrying value of the real estate and related assets.
Real Estate Escrow Deposits	Real Estate Escrow Deposits
	Real estate escrow deposits include funds held by escrow agents and others to be applied towards the purchase of real estate, which are included in other assets in the accompanying consolidated balance sheets.
Fair Value	Fair Value
	Accounting Standards Codification, or ASC, 820, Fair Value Measurements and Disclosures, or ASC 820, defines fair value, establishes a framework for measuring fair value in accordance with GAAP and expands disclosures about fair value measurements. ASC 820 emphasizes that fair value is intended to be a market-based measurement, as opposed to a transaction-specific measurement.
	Fair value is defined by ASC 820 as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate the fair value. Assets and liabilities are measured using inputs from three levels of the fair value hierarchy, as follows:
	Level 1—Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
	Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data correlation or other means (market corroborated inputs).
	Level 3—Unobservable inputs, only used to the extent that observable inputs are not available, reflect the Company’s assumptions about the pricing of an asset or liability.
	The following describes the methods the Company used to estimate the fair value of the Company’s financial assets and liabilities:
	Cash and cash equivalents, restricted cash, tenant receivables, property escrow deposits, prepaid expenses, accounts payable and accrued liabilities—The Company considered the carrying values of these financial instruments, assets and liabilities, to approximate fair value because of the short period of time between origination of the instruments and their expected realization.
	Notes payable – Fixed Rate—The fair value is estimated by discounting the expected cash flows on notes payable at current rates at which management believes similar loans would be made considering the terms and conditions of the loan and prevailing market interest rates.
	Notes payable – Variable Rate—The carrying value of variable rate notes payable approximates fair value because they are interest rate adjustable.
	Notes receivables – The fair value is estimated by discounting the expected cash flows on the notes at interest rates at which management believes similar loans would be made.
	Contingent consideration liabilities—The fair value is estimated by using an income approach, which is determined based on the present value of probability-weighted future cash flows.
	Derivative instruments—The Company’s derivative instruments consist of interest rate swaps. These swaps are carried at fair value to comply with the provisions of ASC 820. The fair value of these instruments is determined using interest rate market pricing models. The Company incorporated credit valuation adjustments to appropriately reflect the Company’s nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Considerable judgement is necessary to develop estimated fair values of financial assets and liabilities. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize, or be liable for on disposition of the financial assets and liabilities.
Revenue Recognition, Tenant Receivables and Allowance for Uncollectible Accounts	Revenue Recognition, Tenant Receivables and Allowance for Uncollectible Accounts
	The Company recognizes revenue in accordance with ASC 605, Revenue Recognition, or ASC 605. ASC 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed and determinable; and (4) collectability is reasonably assured.
	In accordance with ASC 840, Leases, minimum rental revenue is recognized on a straight-line basis over the term of the related lease (including rent holidays). Differences between rental income recognized and amounts contractually due under the lease agreements are credited or charged to deferred rent receivable or deferred rent liability, as applicable. Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses, is recognized as revenue in the period in which the related expenses are incurred. Tenant reimbursements are recognized and presented in accordance with ASC Subtopic 605-45, Revenue Recognition—Principal Agent Consideration, or ASC 605-45. ASC 605-45 requires that these reimbursements be recorded on a gross basis, when the Company is the primary obligor with respect to purchasing goods and services from third-party suppliers and has discretion in selecting the supplier and has credit risk.
	Tenant receivables and unbilled deferred rent receivables are carried net of the allowances for uncollectible amounts. An allowance will be maintained for estimated losses resulting from the inability of certain tenants to meet the contractual obligations under their lease agreements. The Company also maintains an allowance for deferred rent receivables arising from the straight-lining of rents. The Company’s determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s financial condition, security deposits, letters of credit, lease guarantees and current economic conditions and other relevant factors. As of December 31, 2014, the Company did not have an allowance for uncollectible tenant receivables.
Income Taxes	Income Taxes
	The Company currently qualifies and is taxed as a REIT under Sections 856 through 860 of the Code. As a REIT, the Company is required to distribute at least 90% of its taxable income (computed without regard to the dividends paid deduction and excluding capital gains) to its stockholders. In addition, the Company generally is not subject to federal corporate income taxes to the extent it distributes its taxable income to its stockholders. Even if the Company maintains its qualification for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and federal income and excise taxes on its undistributed income.
Concentration of Credit Risk and Significant Leases	Concentration of Credit Risk and Significant Leases
	As of December 31, 2014, the Company had cash on deposit, including restricted cash, in several financial institutions, all of which had deposits in excess of current federally insured levels totaling $124.4 million; however, the Company has not experienced any losses in such accounts. The Company limits its cash investments to financial institutions with high credit standing; therefore, the Company believes it is not exposed to any significant credit risk on its cash deposits. To date, the Company has experienced no loss or lack of access to cash in its accounts. Concentration of credit risk with respect to accounts receivable from tenants is limited.
	As of December 31, 2014, the Company owned real estate investments in 33 MSAs, (including two real estate investments owned through consolidated partnerships), two of which accounted for 10.0% or more of rental revenue. Real estate investments located in the Dallas-Ft. Worth-Arlington, Texas MSA and in the Chicago-Naperville-Elgin, Illinois-Indiana-Wisconsin MSA accounted for an aggregate of 17.2% and 10.0%, respectively, of rental revenue for the year ended December 31, 2014. As of December 31, 2013, the Company owned real estate investments in 24 MSAs, three of which accounted for 10.0% or more of rental revenue. Real estate investments located in the Dallas-Ft. Worth-Arlington, Texas MSA, Atlanta-Sandy Springs-Marietta, Georgia MSA and in the Philadelphia-Camden-Wilmington, Pennsylvania MSA accounted for an aggregate of 24.3%,  18.3% and 11.4%, respectively, of rental revenue for the year ended December 31, 2013. As of December 31, 2012, the Company owned real estate investments in 11 MSAs, two of which accounted for 10.0% or more of rental revenue. Real estate investments located in the Dallas-Ft. Worth-Arlington, Texas MSA and Atlanta-Sandy Springs-Marietta, Georgia MSA accounted for an aggregate of 29.7% and 47.4%, respectively, of rental revenue for the year ended December 31, 2012.
	For the year ended December 31, 2014, the Company’s two reportable business segments, data centers and healthcare, accounted for 56.3% and 43.7%, respectively, of rental revenue. For the year ended December 31, 2013, the Company’s two commercial real estate reportable business segments, data centers and healthcare, accounted for 57.9% and 42.1%, respectively, of rental revenue. For the year ended December 31, 2012, the Company’s two reportable business segments, data centers and healthcare, accounted for 78.8% and 21.2%, respectively, of rental revenue.
	As of December 31, 2014, the Company had one tenant that accounted for 10.0% or more of rental revenue. The leases with AT&T Services, Inc. accounted for 18.5% of rental revenue for the year ended December 31, 2014. As of December 31, 2013, the Company had two tenants that accounted for 10.0% or more of rental revenue. The leases with Level 3 Communications, LLC and the Vanguard Group, Inc. accounted for 10.6% and 11.4%, respectively, of rental revenue for the year ended December 31, 2013. As of December 31, 2012, the Company had two tenants that accounted for 10.0% or more of rental revenue. The leases with Level 3 Communications, LLC and with Catholic Health Initiatives accounted for 26.8% and 16.1%, respectively, of rental revenue for the year ended December 31, 2012.
Stock-based Compensation	Stock-based Compensation
	The Company accounts for stock-based compensation based upon the estimated fair value of the share awards. Accounting for stock-based compensation requires the fair value of the share awards to be amortized as compensation expense over the period for which the services relate and requires any dividend equivalents earned to be treated as dividends for financial reporting purposes. See Note 10—“Stock-based Compensation” for a further discussion of stock-based compensation awards.
Stockholders' Equity	Stockholders’ Equity
	As of December 31, 2014, the Company was authorized to issue 350,000,000 shares of stock, of which 300,000,000 shares are designated as common stock at $0.01 par value per share and 50,000,000 shares are designated as preferred stock at $0.01 par value per share. As of December 31, 2014, the Company had approximately 175,562,000 shares of common stock issued and 175,038,000 shares of common stock outstanding, and no shares of preferred stock issued and outstanding. As of December 31, 2013, the Company had approximately 73,238,000 shares of common stock issued and 73,138,000 shares of common stock outstanding, and no shares of preferred stock issued and outstanding. The Company’s board of directors may authorize additional shares of capital stock and amend their terms without obtaining stockholder approval.
Share Repurchase Program	Share Repurchase Program
	The Company approved a share repurchase program that allows for repurchases of shares of the Company’s common stock when certain criteria are met. The share repurchase program provides that all redemptions during any calendar year, including those upon death or a qualifying disability of a stockholder, are limited to those that can be funded with proceeds raised from the DRIP and the Second DRIP.
	Repurchases of shares of the Company’s common stock are at the sole discretion of the Company’s board of directors. In addition, the Company’s board of directors, at its sole discretion, may amend, suspend, reduce, terminate or otherwise change the share repurchase program upon 30 days prior notice to the Company’s stockholders for any reason it deems appropriate. During the year ended December 31, 2014, the Company received valid redemption requests related to approximately 423,000 shares of common stock, all of which were redeemed in full for an aggregate purchase price of approximately $4,087,000 (an average of $9.66 per share).  During the year ended December 31, 2013, the Company received valid redemption requests related to approximately 80,000 shares of common stock, all of which were redeemed in full for an aggregate purchase price of approximately $783,000 (an average of $9.79 per share).
Distribution Policy and Distributions Payable	Distribution Policy and Distributions Payable
	In order to maintain its status as a REIT, the Company is required to make distributions each taxable year equal to at least 90% of its taxable income, computed without regard to the dividends paid deduction and excluding capital gains. To the extent funds are available, the Company intends to continue to pay regular distributions to stockholders. Distributions are paid to stockholders of record as of the applicable record dates. As of December 31, 2014, the Company had aggregate distributions, since inception, of approximately $127,194,000 ($61,617,000 in cash and $65,577,000 of which were reinvested in shares of common stock pursuant to the DRIP and the Second DRIP), calculated at the current rate of 7.0%. The Company’s distributions declared per common share were $0.70, for the years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, the Company had distributions payable of approximately $10,409,000. Of those payable distributions, $4,711,000 of which were paid in cash and $5,698,000 of which were reinvested in shares of common stock pursuant to the Second DRIP on January 2, 2015.
Earnings Per Share	Earnings Per Share
	Basic earnings (loss) per share attributable for all periods presented are computed by dividing net income (loss) attributable to the Company by the weighted average number of shares of common stock outstanding during the period. Shares of non-vested restricted common stock give rise to potentially dilutive shares of common stock. Diluted earnings (loss) per share are computed based on the weighted average number of shares outstanding and all potentially dilutive securities. For the years ended December 31, 2014 and 2013, diluted earnings per share reflect the effect of approximately 18,000 shares and 17,000 shares, respectively, of non-vested shares of restricted common stock that were outstanding as of such period. For the year ended December 31, 2012, diluted earnings per share reflect the effect of 20,250 shares of non-vested shares of restricted common stock outstanding, but such shares were excluded from the computation of diluted earnings per share because such shares were antidilutive during the period.
Reportable Segments	Reportable Segments
	ASC 280, Segment Reporting, establishes standards for reporting financial and descriptive information about an enterprise’s reportable segments. As disclosed previously, as of December 31, 2014, the Company operated through two reportable business segments – commercial real estate investments in data centers and healthcare. With the continued expansion of the Company’s portfolio, segregation of the Company’s operations into two reporting segments is useful in assessing the performance of the Company’s business in the same way that management reviews performance and makes operating decisions. See Note 15—“Segment Reporting” for further discussion on the reportable segments of the Company.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	As required by ASC 815, Derivatives and Hedging, or ASC 815, the Company records all derivative instruments as assets and liabilities in the statement of financial position at fair value. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in the consolidated statements of comprehensive income (loss) during the current period.
	The Company is exposed to variability in expected future cash flows that are attributable to interest rate changes in the normal course of business. The Company’s primary strategy in entering into derivative contracts is to add stability to future cash flows by managing its exposure to interest rate movements.  The Company utilizes derivative instruments, including interest rate swaps, to effectively convert some its variable rate debt to fixed rate debt. The Company does not enter into derivative instruments for speculative purposes.
	In accordance with ASC 815, the Company designates interest rate swap contracts as cash flow hedges of floating-rate borrowings. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) in the consolidated statements of comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction and the same period during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in the consolidated statements of comprehensive income (loss) during the current period.
	In accordance with the fair value measurement guidance Accounting Standards Update, or ASU, 2011-04, Fair Value Measurement, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board, or the FASB, issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, or ASU 2014-08. ASU 2014-08 changes the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the company’s operations and financial results. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. The adoption of ASU 2014-08 is effective prospectively for reporting periods beginning on or after December 15, 2014. The Company does not expect the adoption of ASU 2014-08 to have a material effect on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. The objective of ASU 2014-09 is to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle, which may require more judgment and estimates within the revenue recognition process than are required under existing GAAP. The adoption of ASU 2014-09 is effective retrospectively for reporting periods beginning after December 15, 2016. Early adoption of ASU 2014-09 is not permitted. The Company is in the process of evaluating the impact ASU 2014-09 will have on the Company’s consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About An Entity’s Ability to Continue As a Going Concern, or ASU 2014-15, which describes how an entity should assess its ability to meet obligations and sets rules for how this information should be disclosed in the financial statements. The adoption of ASU 2014-15 is effective for reporting periods ending after December 15, 2016, early adoption is permitted. The Company is in the process of evaluating the impact ASU 2014-15 will have on the Company’s consolidated financial statements.
	On January 9, 2015, the FASB issued ASU 2015-01, Income Statement-Extraordinary and Unusual Items, or ASU 2015-01, to simplify income statement classification by removing the concept of extraordinary items from GAAP. As a result, items that are both unusual and infrequent will no longer be separately reported net of tax after continuing operations. The standard is effective for periods beginning after December 15, 2015. The Company does not expect the adoption of ASU 2015-01 to have a material effect on the Company’s consolidated financial statements.
Reclassifications	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current financial statement presentation, with no effect on the Company’s consolidated financial position or results of operations.
