Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements and footnotes have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements include the accounts of RealPage, Inc. and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Segment and Geographic Information Our chief operating decision maker is our Chief Executive Officer, who reviews financial information presented on a company-wide basis. As a result, we determined that the Company has a single reporting segment and operating unit structure. Principally, all of our revenue for the years ended December 31, 2016 , 2015 , and 2014 was earned in the United States. Net property, equipment, and software held were $125.3 million and $77.4 million located in the United States, and $5.1 million and $4.8 million in our international subsidiaries at December 31, 2016 and 2015 , respectively. Substantially all of the net property, equipment, and software held in our international subsidiaries was located in the Philippines, Spain, and India at both December 31, 2016 and 2015 . Use of Estimates The preparation of financial statements in conformity with GAAP requires our management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the allowance for doubtful accounts; the useful lives of intangible assets and the recoverability or impairment of tangible and intangible asset values; fair value measurements; contingent commissions related to the sale of insurance products; purchase accounting allocations and contingent consideration; revenue and deferred revenue and related reserves; stock-based expense; and our effective income tax rate and the recoverability of deferred tax assets, which are based upon our expectations of future taxable income and allowable deductions. Actual results could differ from these estimates. The Company is self-insured for the cost of claims made under its employee medical programs. These costs include an estimate for expected settlements of pending claims and an estimate for claims incurred but not reported. These significant estimates are based on management's assessment of outstanding claims, historical analyses, and current payment trends. Concentrations of Credit Risk Our cash accounts are maintained at various financial institutions and may, from time to time, exceed federally insured limits. The Company has not experienced any losses in such accounts. Concentrations of credit risk with respect to accounts receivable result from substantially all of our clients being in the multifamily rental housing market. Our clients, however, are dispersed across different geographic areas. We do not require collateral from clients. We maintain an allowance for doubtful accounts based upon the expected collectability of accounts receivable. No single client accounted for 10% or more of our revenue or accounts receivable for the years ended December 31, 2016 , 2015 , or 2014 . Revenues for our largest client were 5.7% , 4.6% , and 4.9% of our total revenues for the years ended December 31, 2016 , 2015 , and 2014 , respectively. Cash and Cash Equivalents We consider all highly liquid investments with a maturity date, when purchased, of three months or less to be cash equivalents. Restricted Cash Restricted cash consists of cash collected from tenants that will be remitted primarily to our clients. Accounts Receivable Accounts receivable primarily represent trade receivables from clients that we present net of an allowance for doubtful accounts. For several of our solutions, we invoice clients prior to the period in which service is provided. For certain transactions, we have met the requirements to recognize revenue in advance of invoicing the client. In these instances, we record unbilled receivables for the amount that will be due from the client upon invoicing. We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of clients to make required payments, or the client canceling prior to the service being rendered. As a result, a portion of our allowance is for services not yet rendered and, therefore, classified as an offset to deferred revenue. In evaluating the sufficiency of the allowance for doubtful accounts we consider the current financial condition of the client, the specific details of the client account, the age of the outstanding balance, the current economic environment, and historical credit trends. Any change in the assumptions used in analyzing a specific account receivable might result in an additional allowance for doubtful accounts being recognized in the period in which the change occurs. Accounts receivable are written off upon determination of non-collectability following established Company policies based on the aging from the accounts receivable invoice date. In the case of balances relating to services not yet rendered, the balance is written off when the client cancels the service or when we determine that the invoiced service will no longer be provided, whichever occurs first. During the years ended December 31, 2016 , 2015 , and 2014 , we incurred bad debt expense of $2.4 million , $2.0 million , and $1.5 million , respectively. Accounts receivable includes commissions due to the Company related to the sale of insurance products to individuals and commissions which are contingent based upon the activity in the underlying policies. Contingent commissions are determined based on a calculation that considers earned agent commissions, a percent of premium retained by our underwriting partner, incurred losses, and profit retained by our underwriting partner during the time period. Contingent commissions receivables are recorded at their estimated net realizable value, based on estimates and considerations which include, but are not limited to, the historical and projected loss rates incurred by the underlying policies. Inventory Inventories are stated at the lower of net realizable value or cost, determined on a first-in, first-out basis. The Company establishes inventory allowances for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated realizable values based on assumptions about forecasted demand, open purchase commitments, and market conditions. Inventories consist primarily of meters, including subcontract labor costs on contracts in progress. Property, Equipment, and Software Property, equipment, and software are recorded at cost less accumulated depreciation and amortization, which are computed using the straight-line method over the following estimated useful lives: Data processing and communications equipment 3 - 5 years Furniture, fixtures, and other equipment 3 - 5 years Software 3 - 5 years Software includes both purchased and internally developed software. Leasehold improvements are depreciated over the shorter of the lease term or twelve years . Gains and losses from asset disposals are included in the line "General and administrative" in the Consolidated Statements of Operations. Capitalized Product Development Costs We capitalize specific product development costs, including costs to develop software products or the software components of our solutions to be marketed to external users, as well as software programs to be used solely to meet our internal needs. The costs incurred in the preliminary stages of development related to research, project planning, training, maintenance, general and administrative activities, and overhead costs are expensed as incurred. The costs of relatively minor upgrades and enhancements to the software are also expensed as incurred. Once an application has reached the development stage, internal and external costs incurred in the performance of application development stage activities, including costs of materials, services, and payroll and payroll-related costs for employees, are capitalized, if direct and incremental, until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing. We also capitalize costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Capitalized costs are recorded as part of property, equipment, and software. Internal use software is amortized on a straight-line basis over its estimated useful life, generally three to five years . Our management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Impairment of Long-Lived Assets We perform an impairment review of long-lived assets held and used whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to, significant under-performance relative to current and historical or projected future operating results, significant changes in the manner of our use of the asset, or significant changes in our overall business and/or product strategies. When we determine that the carrying value of a long-lived asset may not be recoverable based upon the existence of one or more of these indicators, we determine the recoverability by comparing the carrying amount of the asset or asset group to net future undiscounted cash flows that the asset is expected to generate. If the asset or asset group fails this recoverability test, we would recognize an impairment charge equal to the excess of the asset's carrying value over its fair market value. Business Combinations The Company applies the guidance contained in ASC Topic 805, Business Combinations (“ASC 805”) in determining whether an acquisition transaction constitutes a business combination. ASC 805 defines a business as consisting of inputs and processes applied to those inputs that have the ability to create outputs. The acquisition transactions in Note 3 were determined to constitute business combinations and were accounted for under ASC 805. Purchase consideration includes assets transferred, liabilities incurred, and/or equity interests issued by us, all of which are measured at their fair value as of the date of acquisition. Our business combination transactions may be structured to include an up-front cash payment and deferred and/or contingent cash payments to be made at specified dates subsequent to the date of acquisition. Deferred cash payments are included in the acquisition consideration based on their fair value as of the acquisition date. The fair value of these obligations is estimated based on the present value, as of the date of acquisition, of the anticipated future payments. The future payments are discounted using a rate that considers an estimate of the return expected by a market-participant and a measurement of the risk inherent in the cash flows, among other inputs. Deferred cash payments are generally subject to adjustments specified in the underlying purchase agreement related to the seller’s indemnification obligations. Contingent cash payments are obligations to make future cash payments to the seller, the payment of which is contingent upon the achievement of stipulated operational or financial targets in the post-acquisition period. Contingent cash payments are included in the purchase consideration at their fair value as of the acquisition date. The fair value of these payments is estimated using a probability weighted discount model based on the achievement of the specified targets. The fair value of these liabilities is re-evaluated on a quarterly basis, and any change is reflected in the line “General and administrative” in the accompanying Consolidated Statements of Operations. These estimates are inherently uncertain and unpredictable. Unanticipated events and circumstances may occur that would affect the accuracy or validity of these estimates. The total purchase consideration is allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess consideration is classified as goodwill. Acquired intangibles are recorded at their estimated fair value based on the income approach using market-based estimates. Acquired intangibles generally include developed product technologies, which are amortized over their useful life on a straight-line basis, and client relationships, which are amortized over their useful life proportionately to the expected discounted cash flows derived from the asset. When trade names acquired are not classified as indefinite-lived, they are amortized on a straight-line basis over their expected useful life. Acquisition costs are expensed as incurred and are included in the line “General and administrative” in the accompanying Consolidated Statements of Operations. We include the results of operations from acquired businesses in our consolidated financial statements from the effective date of the acquisition. Goodwill and Identified Intangible Assets with Indefinite Lives We test goodwill and identified intangible assets with indefinite lives for impairment separately on an annual basis in the fourth quarter of each year. Additionally, we test these assets in the interim if events and circumstances indicate they may be impaired. The events and circumstances that we consider include, but are not limited to, significant under-performance relative to current and historical or projected future operating results and significant changes in our overall business and/or product strategies. If an event or circumstance occurs that would cause us to revise our estimates and assumptions used in analyzing the value of our goodwill and identified intangible assets with indefinite lives, the revision could result in a non-cash impairment charge that could have a material impact on our financial results. We evaluate impairment of goodwill by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the two-step goodwill impairment test. The first step involves a comparison of the fair value of a reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step involves a comparison of the implied fair value and carrying amount of the goodwill of that reporting unit to determine the impairment charge, if any. We quantitatively evaluate identified intangible assets with indefinite lives by estimating the fair value of those assets based on estimated future earnings derived from the assets using the income approach model. Assets with indefinite lives that have been determined to be inseparable due to their interchangeable use are grouped into single units of accounting for purposes of testing for impairment. If the carrying amount of an identified intangible asset with an indefinite life exceeds its fair value, we would recognize an impairment loss equal to the excess of carrying value over fair value. Identified Intangible Assets with Finite Lives Identified intangible assets with finite lives consist of acquired developed technologies, client relationships, vendor relationships, and trade names. We record intangible assets at fair value and amortize those with finite lives over the shorter of the contractual life or the estimated useful life. We estimate the useful lives of acquired developed product technologies and client relationships based on factors that include the planned use of each developed product technology and the expected pattern of future cash flows to be derived from each developed product technology and existing client relationships. Estimated useful lives for identified intangible assets with finite lives consist of the following: Developed technologies 3 - 5 years Client relationships 3 - 10 years Vendor relationships 7 years Trade names 1 - 7 years We include amortization of acquired developed technologies in "Cost of revenue" and amortization of acquired client relationships, vendor relationships and trade names in "Sales and marketing" expenses in our Consolidated Statements of Operations. Derivative Financial Instruments The Company is exposed to interest rate risk related to our variable rate debt. The Company manages this risk through a program that may include the use of interest rate derivatives, the counterparties to which are major financial institutions. Our objective in using interest rate derivatives is to add stability to interest cost by reducing our exposure to interest rate movements. We do not use derivative instruments for trading or speculative purposes. Our interest rate derivatives are designated as cash flow hedges and are carried in the Consolidated Balance Sheets at their fair value. Unrealized gains and losses resulting from changes in the fair value of these instruments are classified as either effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income (“AOCI”), while the ineffective portion is recorded as a component of interest expense in the period of change. Amounts reported in AOCI related to interest rate derivatives are reclassified into interest expense as interest payments are made on our variable-rate debt. If an interest rate derivative agreement is terminated prior to its maturity, the amounts previously recorded in AOCI are recognized into earnings over the period that the forecasted transactions impact earnings. If the hedging relationship is discontinued because it is probable that the forecasted transactions will not occur according to our original strategy, any related amounts previously recorded in AOCI are recognized in earnings immediately. Other Current and Long-Term Liabilities Accrued expenses and other current liabilities consisted of the following at December 31, 2016 and 2015 : December 31, 2016 2015 (in thousands) Accrued compensation, payroll taxes, and benefits $ 19,387 $ 12,492 Self-insured medical plans 1,774 1,831 Current portion of liabilities related to acquisitions 13,084 6,502 Other current liabilities 16,219 7,469 Total accrued expenses and other current liabilities $ 50,464 $ 28,294 Other long-term liabilities consisted of the following at December 31, 2016 and 2015 : December 31, 2016 2015 (in thousands) Accrued lease liability $ 28,086 $ 27,869 Other long-term liabilities 1,757 6,554 Total other long-term liabilities $ 29,843 $ 34,423 The accrued lease liability at December 31, 2016 and 2015 primarily consisted of deferred rent amounts related to our corporate headquarters in Richardson, Texas. See Note 9 for additional information regarding this lease. Deferred Revenue Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from our subscription services described above and is recognized as the revenue recognition criteria are met. For several of our solutions, we invoice our clients in annual, monthly, or quarterly installments in advance of the commencement of the service period. Accordingly, the deferred revenue balance does not represent the total contract value of annual subscription agreements. Revenue Recognition We derive our revenue from three primary sources: on demand software solutions, on premise software solutions, and professional services. We commence revenue recognition when all of the following conditions are met: • there is persuasive evidence of an arrangement; • the solution and/or service has been provided to the client; • the collection of the fees is probable; and • the amount of fees to be paid by the client is fixed or determinable. If the fees are not fixed or determinable, we recognize revenues as payments become due from clients or when amounts owed are collected, provided all other conditions for revenue recognition have been met. Accordingly, this may materially affect the timing of our revenue recognition and results of operations. When arrangements with clients include multiple software solutions and/or services, we allocate arrangement consideration to each deliverable based on its relative selling price. In such circumstances, we determine the relative selling price for each deliverable based on vendor specific objective evidence of selling price ("VSOE"), if available, or our best estimate of selling price ("BESP"). We have determined that third-party evidence of selling price is not available as our solutions and services are not largely interchangeable with those of other vendors. Our process for determining BESP considers multiple factors, including prices charged by us for similar offerings when sold separately, pricing and discount strategies, and other business objectives. Taxes collected from clients and remitted to governmental authorities are presented on a net basis. On Demand Revenue Our on demand revenue consists of license and subscription fees, transaction fees related to certain of our software-enabled value-added services, and commissions derived from our selling certain risk mitigation services. License and subscription fees are comprised of a charge billed at the initial order date and monthly or annual subscription fees for accessing our on demand software solutions. The license fee billed at the initial order date is recognized as revenue on a straight-line basis over the longer of the contractual term or the period in which the client is expected to benefit, which we consider to be three years. Recognition starts once the product has been activated. Revenue from monthly and annual subscription fees is recognized on a straight-line basis over the access period. We recognize revenue from transaction fees derived from certain of our software-enabled value-added services as the related services are performed. As part of our risk mitigation services to the rental housing industry, we act as an insurance agent and derive commission revenue from the sale of insurance products to individuals. The commissions are based upon a percentage of the premium that the insurance company charges to the policyholder and are subject to forfeiture in instances where a policyholder cancels prior to the end of the policy. Our contract with our underwriting partner provides for contingent commissions to be paid to us in accordance with the agreement. This agreement provides for a calculation that considers, on the policies sold by us, earned premiums less i) earned agent commissions, ii) a percent of premium retained by our underwriting partner, iii) incurred losses, and iv) profit retained by our underwriting partner during the time period. Our estimate of contingent commission revenue considers historical loss experience on the policies sold by us. If the policy is cancelled, our commissions are forfeited as a percent of the unearned premium. As a result, we recognize commissions related to these services as earned ratably over the policy term. On Premise Revenue Sales of our on premise software solutions consist of an annual term license, which includes maintenance and support. Clients can renew their annual term license for additional one -year terms at renewal price levels. We recognize revenue for the annual term license and support services on a straight-line basis over the contract term. We also derive on premise revenue from multiple-element arrangements that include perpetual licenses with maintenance and other services to be provided over a fixed term. Revenue is recognized for delivered items using the residual method when we have VSOE of fair value for the undelivered items and all other criteria for revenue recognition have been met. When VSOE has not been asserted for the undelivered items, we recognize the arrangement fees ratably over the longer of the client support period or the period during which professional services are rendered. Professional and Other Revenue Professional services and other revenue are recognized as the services are rendered for time and material contracts. Training revenues are recognized after the services are performed. Cost of Revenue Cost of revenue consists primarily of salaries and related personnel expenses of our operations and support personnel, including training and implementation services; expenses related to the operation of our data centers; fees paid to third-party providers; allocations of facilities overhead costs; depreciation; amortization of acquired technologies; and amortization of capitalized software. Stock-Based Expense The Company recognizes compensation expense related to stock options and shares of restricted stock based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The Company generally grants time-based stock options and restricted stock awards, which vest over a specified period of time; market-based awards, which become eligible to vest only after the achievement of a condition based upon the trading price of the Company's common stock and vest over a specified period of time thereafter; and performance-based awards, which become eligible to vest upon the achievement of a specific performance condition, after which they vest over a specified period of time. For time-based stock options and restricted stock awards and performance-based awards, expense is recognized on a straight-line basis over the requisite service period. Expense associated with market-based awards is recognized over the requisite service period using the graded-vesting attribution method. Advertising Expenses Advertising costs are expensed as incurred and totaled $19.4 million , $16.3 million , and $15.1 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. Income Taxes Income taxes are provided based on the liability method, which results in income tax assets and liabilities arising from temporary differences. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. The liability method requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period in which the rate change was enacted. The liability method also requires that deferred tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized. We establish valuation allowances when necessary to reduce deferred tax assets to the amounts expected to be realized. We evaluate the need for, and the adequacy of, valuation allowances based on the expected realization of our deferred tax assets. The factors used to assess the likelihood of realization include historical earnings, our latest forecast of taxable income, and available tax planning strategies that could be implemented to realize the net deferred tax assets. We may recognize a tax benefit from uncertain tax positions only if it is at least more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon settlement with the taxing authorities. There were no identified tax benefits that were considered uncertain positions at December 31, 2016 and 2015 . Leases Some of the operating lease agreements entered into by the Company contain provisions for future rent increases, rent free periods, periods in which rent payments are reduced (abated), or lease incentives. The total amount of rental payments due over the lease term is charged to rent expense on the straight-line method over the term of the lease. The difference between rent expense recorded and the amount paid is credited or charged to “Accrued lease liability,” which is included in “Accrued expenses and other current liabilities" or "Other long-term liabilities" in the accompanying Consolidated Balance Sheets, depending upon when the liability is expected to be relieved. Fair Value Measurements Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Legal Contingencies We review the status of each legal contingency and record a provision for a liability when we consider that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. We review these provisions quarterly and make adjustments where needed as additional information becomes available. If either or both of the criteria are not met, we assess whether there is at least a reasonable possibility that a loss, or additional losses beyond those already accrued, may be incurred. If there is a reasonable possibility that a material loss (or additional material loss in excess of any accrual) may be incurred, we disclose an estimate of the amount of loss or range of losses, either individually or in the aggregate, as appropriate, if such an estimate can be made, or disclose that an estimate of loss cannot be made. Recently Adopted Accounting Standards We adopted Accounting Standards Update (“ASU”) 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs and ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Agreements in the first quarter of 2016. As a result of our retrospective adoption of these standards, we present term loans payable net of unamortized debt issuance costs in the Consolidated Balance Sheets. Prior to adoption of this ASU, such issuance costs were included in other assets. Our adoption of this standard did not result in a reclassification of previously reported amounts, as we did not have outstanding term loans at December 31, 2015. As required, debt issuance costs related to our secured revolving facility continue to be presented in "Other assets" in the Consolidated Balance Sheets. In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments , which eliminates the requirement to restate prior period financial statements for measurement-period adjustments. This ASU requires that the cumulative impact of a measurement period adjustment, including the impact on prior periods, be recognized in the reporting period in which the adjustment is identified. We adopted ASU 2015-16 in the first quarter of 2016. In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This ASU provides guidance to clarify the customer’s accounting for fees paid in a cloud computing arrangement and whether such an arrangement contains a software license or is solely a service contract. We adopted this standard in the first quarter of 2016 and prospectively applied the guidance to all arrangements entered into or materially modified after January 1, 2016. Recently Issued Accounting Standards In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business to assist entities with evaluating whether a set of transferred assets and activities ("set") is a business . Under the new guidance, an entity first determines whether substantially all of the fair value of the set is concentrated in a single identifiable asset or a group of similar identifiable assets.

Business Combinations [Abstract]
Acquisitions	Acquisitions 2016 Acquisitions eSupply Systems, LLC In June 2016, we acquired substantially all of the assets of eSupply Systems, LLC (“eSupply”) and those of certain entities related to eSupply. eSupply is an e-procurement software and group purchasing service which augmented our Spend Management solutions. We acquired eSupply for a purchase price of $7.0 million , consisting of a cash payment of $5.5 million at closing and a deferred cash obligation of up to $1.6 million , payable over 18 months after the acquisition date. The fair value of the deferred cash obligation on the date of acquisition was $1.5 million . The first deferred cash payment was made in the fourth quarter of 2016. This acquisition was financed using proceeds from the Term Loan issued in February 2016. The acquired identified intangible assets consisted of developed technology and client relationships. These intangible assets were assigned estimated useful lives of three and ten years , respectively. We recognized goodwill in the amount of $3.2 million related to this acquisition, which is primarily comprised of anticipated synergies with our existing Spend Management solutions. Goodwill and the acquired identified intangible assets are deductible for tax purposes. AssetEye, Inc. In May 2016, we acquired all of the issued and outstanding stock of AssetEye, Inc. (“AssetEye”). AssetEye is a data aggregation, reporting, and collaboration platform for institutions holding multiple real estate asset classes. This solution provides asset and portfolio managers with a solution to evaluate performance, trends, and operations across a portfolio with transparency into property-level data. The acquisition of AssetEye expanded the Company’s on demand solutions to serve all asset classes, including: commercial, hospitality, multifamily, single family, senior living, and student housing. We acquired AssetEye’s issued and outstanding stock for a purchase price of $4.9 million . The purchase price consisted of a cash payment of $3.6 million at closing, net of cash acquired of $0.8 million ; deferred cash obligations of $1.0 million , payable over a period of two years following the date of acquisition; contingent cash payments of up to $1.0 million if certain revenue targets are achieved during the three-month period ended September 30, 2017 ; and additional cash payments of $0.2 million due to former shareholders of AssetEye which are expected to be remitted over a short-term period. The fair value of the deferred and contingent cash obligations was $0.9 million and $0.2 million , respectively, at the date of acquisition. This acquisition was financed with proceeds from the Term Loan issued in February 2016. The acquired identified intangible assets included developed technology and client relationships having useful lives of five and ten years , respectively. We recognized goodwill in the amount of $3.2 million related to this acquisition, which is primarily comprised of anticipated synergies between the AssetEye solution and our existing complementary solutions as well as our sales and marketing infrastructure. Goodwill and identified intangible assets recognized in connection with this transaction are not deductible for tax purposes. NWP Services Corporation In March 2016, we acquired all of the issued and outstanding stock of NWP Services Corporation (“NWP”). NWP provides a full range of utility management services, including: resident billing; payment processing; utility expense management; analytics and reporting; sub-metering and maintenance; and regulatory compliance. The primary products offered by NWP include Utility Logic, Utility Smart, Utility Genius, SmartSource, and NWP Sub-meter. We are integrating NWP into our resident services product family. The integrated platform will enable property owners and managers to increase the collection of rental utilities and energy recovery. Goodwill arising from this acquisition consists of anticipated synergies from the integration of NWP into our existing structure. We acquired NWP’s issued and outstanding stock for an initial purchase price of $69.0 million . The purchase price consisted of a cash payment of $59.0 million at closing, net of cash acquired of $0.1 million ; deferred cash obligations of $7.2 million , payable over a period of three years following the date of acquisition; and other amounts totaling $3.2 million , consisting of payments to certain employees and former shareholders of NWP that are expected to be remitted over a short-term period. The acquisition-date fair value of the deferred cash obligation was $6.8 million . This acquisition was financed with proceeds from the Term Loan issued in February 2016. Acquisition costs associated with this transaction totaled $0.3 million and were expensed as incurred. The acquired identified intangible assets were comprised of developed technologies, trade name, and client relationships having useful lives of five , three , and ten years , respectively. Goodwill and identified intangible assets acquired in this business combination, valued at $35.3 million and $16.3 million in our initial purchase price allocation, have carryover tax bases of $0.7 million and $11.0 million , respectively, which are deductible for tax purposes. Goodwill and identified intangible assets recognized in excess of those carryover tax basis amounts are not deductible for tax purposes. Accounts receivable acquired had a gross contractual value of $11.3 million at acquisition, of which $3.4 million was estimated to be uncollectible. We assigned approximately $10.2 million of value to deferred tax assets in our initial purchase price allocation, consisting primarily of $9.9 million of federal and state net operating losses (“NOL”). This NOL amount reflects the tax benefit from approximately $27.3 million of NOLs we expect to realize after considering various limitations and restrictions on NWP’s pre-acquisition NOLs. In connection with the acquisition of NWP, we recorded an indemnification asset of $1.2 million , which represents the selling security holders’ obligation under the purchase agreement to indemnify the Company for the outcome of certain accrued obligations. The indemnification asset was recognized on the same basis as the corresponding liability, which is based on its estimated fair value as of the date of acquisition. Subsequent to the acquisition date, management continued to review information relating to events and circumstances that existed at the acquisition date. This review resulted in measurement period adjustments to the provisional amounts recorded at the acquisition date related to deferred cash obligations paid to the sellers and deferred tax assets associated with the transaction. These measurement period adjustments resulted in a change in goodwill, deferred tax assets, and the deferred cash obligation of $(1.8) million , $1.0 million , and $(0.8) million , respectively. Purchase Price Allocation The estimated fair values of assets acquired and liabilities assumed presented below are provisional and are based on the information available as of the acquisition date. We believe that this information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed, but the Company is awaiting additional information necessary to finalize those values. Therefore, the provisional measurements of fair value are subject to change, and such changes could be significant. We expect to finalize the valuation of these assets and liabilities as soon as practicable, but no later than one year from the respective acquisition dates. The preliminary allocation of each purchase price, including the effects of the measurement period adjustments described above, was as follows: NWP AssetEye eSupply (in thousands) Restricted cash $ 4,960 $ — $ — Accounts receivable 7,902 90 259 Property, equipment, and software 3,194 — — Intangible assets: Developed product technologies 2,740 1,638 2,160 Client relationships 12,900 1,041 1,390 Trade names 709 6 35 Goodwill 33,520 3,154 3,216 Deferred tax assets, net 11,173 — — Other assets, net of other liabilities 3,065 8 71 Accounts payable and accrued liabilities (6,962 ) — (147 ) Client deposits held in restricted accounts (5,018 ) — — Deferred revenue — (16 ) (29 ) Deferred tax liabilities, net — (1,010 ) — Total purchase price $ 68,183 $ 4,911 $ 6,955 At December 31, 2016 , deferred cash obligations related to acquisitions completed in 2016 totaled $8.7 million , and are carried net of a discount of $1.2 million in the Consolidated Balance Sheets. The aggregate fair value of contingent cash obligations related to these acquisitions was $0.5 million at December 31, 2016 . During the year ended December 31, 2016 , we recognized a loss of $0.3 million due to changes in the fair value of contingent cash obligations related to these acquisitions. We made deferred cash payments of $0.1 million during the year ended December 31, 2016 , related to these acquisitions. During the same period, we made payments totaling $3.3 million related to amounts due to certain employees and former shareholders of the acquired businesses described above. There were no payments of contingent cash obligations made related to these acquisitions during the year ended December 31, 2016 . 2015 Acquisitions Indatus In June 2015, we acquired certain assets from ICIM Corporation, including the Answer Automation, Call Tracker, and Zip Digital products, marketed under the name Indatus. The Indatus offerings are software-as-a-service ("SaaS") products that provide automated answering services, marketing spend analysis tools, and other features which enhance the ability of managers of multifamily properties to communicate with their residents. We are currently integrating the Indatus assets with our existing contact center and maintenance products, which will increase the features of these existing solutions. We acquired the Indatus assets for a purchase price of $49.4 million , consisting of a cash payment of $43.8 million at closing; deferred cash payments of up to $5.0 million , payable over nineteen months after the acquisition date; and contingent cash payments of up to $2.0 million , in the aggregate, if certain revenue targets are met for the twelve months ending June 30, 2016 and 2017 . The first deferred cash payment was made in the third quarter of 2016. The contingent consideration revenue targets for the twelve-month period ended June 30, 2016 , were not achieved and no payment was made. If the revenue targets for the second twelve-month period are achieved, the maximum potential contingent consideration payment is $2.0 million . The fair value of the deferred and contingent cash payments was $4.7 million and $0.9 million , respectively, as of the acquisition date. Direct acquisition costs were $0.3 million and the acquisition was financed using proceeds from our Revolving Facility. The acquired developed product technologies and client relationships have useful lives of three and ten years , respectively. The trade name acquired was amortized over a useful life of one year , based on our anticipated use of the asset. Goodwill and identified intangible assets associated with the acquisition are deductible for tax purposes. Goodwill arising from the acquisition consisted largely of synergies from the integration of Indatus with our pre-existing products and from leveraging our existing client base and sales staff. VRX In June 2015, we acquired certain assets from RJ Vacations, LLC and Switch Development Corporation, including the VRX product (“VRX”). VRX is a SaaS application which allows vacation rental management companies to manage the cleaning and turning of units, accounting, and document management. We integrated VRX with our Kigo vacation rental solution. We acquired the VRX assets for a purchase price of $2.0 million , consisting of a cash payment of $1.5 million at closing and a contingent cash payment of up to $0.5 million . Payment of the contingent cash obligation was dependent upon the achievement of certain subscription or booking activity targets and is subject to adjustments specified in the acquisition agreement related to the sellers’ indemnification obligations. The contingent cash obligation had a fair value of $0.5 million , as of the acquisition date, and was due fifteen months after the date of acquisition. The acquisition agreement also provided for the sellers to receive additional contingent cash payments of up to $3.0 million . Payment of the additional contingent cash obligations is dependent upon the achievement of certain revenue targets during the twelve month periods ending December 31, 2016, 2017, and 2018, and the sellers providing certain services during a specified period following the acquisition date. Due to this post-acquisition service requirement, the Company concluded that the additional contingent cash obligations represent post-acquisition compensation; therefore, these amounts were excluded from the purchase consideration. The revenue targets for the first contingent cash payment were not met. Additionally, one of the sellers separated from the Company prior to completing the required service period. As a result of this separation, the maximum potential payout of the remaining contingent cash payments is $1.5 million . This acquisition was financed using cash flows from operations. The acquired developed product technologies have an estimated useful life of three years . The estimated fair value of the client relationships acquired was immaterial and these intangible assets were expensed as of the acquisition date. Goodwill arising from the acquisition consisted largely of synergies from the integration of VRX with Kigo. Goodwill and identified intangible assets associated with the acquisition are deductible for tax purposes. Purchase Price Allocation We allocated the purchase price of Indatus and VRX as follows: Indatus VRX (in thousands) Accounts receivable $ 646 $ — Intangible assets: Developed product technologies 13,400 794 Client relationships 9,770 11 Trade names 83 — Goodwill 25,575 1,186 Other liabilities, net of other assets (57 ) — Total purchase price $ 49,417 $ 1,991 At December 31, 2016 and 2015 , deferred cash obligations related to acquisitions completed in 2015 totaled $2.5 million and $5.1 million , and were carried net of a discount of $0.1 million and $0.2 million , respectively. Payments of deferred cash obligations related to these acquisitions totaling $2.4 million were made during the twelve months ended December 31, 2016 . The aggregate fair value of contingent cash obligations related to acquisitions completed in 2015 was immaterial at December 31, 2016 , and $0.8 million at December 31, 2015 . During the years ended December 31, 2016 and 2015 , we recognized a net gain in the amount of $0.8 million and $0.6 million , respectively, due to changes in the fair value of the contingent cash obligations related to these acquisitions. There were no payments of contingent cash obligations made related to these acquisitions during the years ended December 31, 2016 and 2015 . 2014 Acquisitions InstaManager In January 2014, we acquired certain assets from Bookt LLC, including the InstaManager product (“InstaManager”). InstaManager was a SaaS vacation rental booking engine used by professional managers of vacation rental properties which offered marketing websites; online pricing and availability; online booking; automated reservations; payment processing; and insurance sales. The acquisition of InstaManager expanded our product offerings to include property management software for the vacation rental market. We acquired InstaManager for a purchase price of $9.2 million , consisting of a cash payment of $6.0 million at closing; a deferred cash payment of up to $1.0 million , payable over two years after the acquisition date; and contingent cash payments totaling up to $7.0 million if certain revenue targets were met during the twelve month periods ended March 31, 2015 and 2016 . The initial fair values of the deferred and contingent cash payments were $0.8 million and $2.4 million , respectively. The deferred cash obligations were paid in the first quarters of 2015 and 2016. The performance target for the first contingent cash payment was achieved and the related payment was made in the third quarter of 2015. The second contingent cash target was not achieved and expired in the first quarter of 2016. The acquired developed product technologies have a useful life of three years . Goodwill and identified intangible assets associated with this acquisition are deductible for tax purposes. Goodwill arising from the acquisition consisted largely of economies of scale from the integration of InstaManager into our pre-existing operating structure. This acquisition was financed using cash flows from operations. We assigned an indefinite useful life to the trade name acquired, as we did not anticipate ceasing use of the trade name in the marketplace. In March 2015, we completed the integration of InstaManager with another vacation rental software product and concurrently ceased use of the trade name in marketing activities. As a result of this event, we assessed the InstaManager trade name for impairment. See further discussion of this analysis and conclusion in Note 6 . Virtual Maintenance Manager In March 2014, we acquired certain assets from Virtual Maintenance Manager LLC, including the Virtual Maintenance Manager product (“VMM”). VMM is a SaaS product that facilitates the management of the end-to-end maintenance life cycle for single family and multifamily rental properties and provides property managers with enhanced visibility into their maintenance costs, manages resources, and provides enhanced business control for property managers. We integrated VMM into our existing Propertyware products. We acquired the VMM assets for a purchase price of $1.2 million , consisting of a cash payment of $1.0 million at closing; deferred cash payments of up to $0.2 million , payable over two years after the acquisition date; and contingent cash payments of up to $2.0 million if certain revenue targets were met for the twelve-month periods ended June 30, 2015 and 2016 . The initial fair value of the deferred and contingent cash payments was $0.2 million and less than $0.1 million , respectively. The deferred cash obligation was paid in the second quarters of 2015 and 2016. The contingent cash targets were not achieved and expired in the second quarter of 2016. The acquired developed product technologies and client relationships were assigned useful lives of three and ten years , respectively. Goodwill and identified intangible assets associated with this acquisition are deductible for tax purposes. Goodwill arising from the acquisition consisted largely of economies of scale from the integration of VMM into our pre-existing operating structure and from synergies with our existing products. The acquisition of VMM was financed using cash flows from operations. Notivus In May 2014, we acquired certain assets from Notivus Multi-Family LLC, including the Notivus product ("Notivus"). Notivus is a SaaS application that provides an outsourced vendor credentialing solution to assist multifamily owners and managers in the credentialing and ongoing monitoring of their current and prospective vendors, suppliers, and independent contractors. We subsequently integrated Notivus into our existing Compliance Depot products. We acquired the Notivus assets for a purchase price of $4.4 million , consisting of a cash payment of $3.6 million at closing and a deferred cash payment of up to $0.8 million , payable over two years after the acquisition date. The initial fair value of the deferred cash payment was approximately $0.8 million . The deferred cash payments were made in the third quarter of 2015 and the second quarter of 2016. The acquired developed product technologies were assigned a useful life of three years . Goodwill and identified intangible assets associated with this acquisition are deductible for tax purposes. Goodwill arising from the acquisition consisted largely of the economies of scale from the integration of Notivus into our pre-existing operating structure and from synergies with our existing products. This acquisition was financed using cash flows from operations. Kigo In June 2014, we acquired all of the issued and outstanding stock of Kigo, Inc. ("Kigo"). Kigo is a SaaS vacation rental booking system based in the United States with operations in Spain. Kigo offers services for vacation rental property managers that include vacation rental calendars, scheduling, reservations, accounting, channel management, website design, payment processing, and other tasks to aid the management of leads, revenue, resources, and lodging calendars. We integrated our existing vacation rental products with Kigo and launched an enhanced version of the software in March 2015. We acquired Kigo for a purchase price of $36.2 million , consisting of a cash payment of $30.7 million and a deferred cash payment of up to $5.5 million , payable over two and a half years after the acquisition date. Interest is accrued on the deferred cash payment at a rate equal to the one-month London Interbank Offered Rate ("LIBOR"), plus a premium of 1.00% , and is payable on the date the underlying principal is due. The first deferred cash payment was made in the first quarter of 2016. This acquisition was financed from proceeds from our Revolving Facility and cash flows from operations. Direct acquisition costs were $0.5 million . The acquired developed product technologies and client relationships were assigned useful lives of three and ten years , respectively. The trade name acquired has an indefinite useful life as we do not plan to cease using it in the marketplace. Goodwill and identified intangible assets associated with this acquisition are not deductible for tax purposes. Goodwill arising from the acquisition consisted largely of the economies of scale from the integration of Kigo into our pre-existing operating structure and from synergies with our existing products. Purchase Price Allocation We allocated the purchase price for InstaManager, VMM, Notivus, and Kigo as follows: InstaManager VMM Notivus Kigo (in thousands) Intangible assets Developed technologies $ 4,490 $ 671 $ 1,840 $ 2,570 Client relationships — 200 — 1,120 Trade names 527 — — 602 Goodwill 4,135 358 2,852 32,996 Deferred revenue (33 ) — (156 ) — Deferred tax liabilities, net — — — (495 ) Net other assets (liabilities) 55 — (141 ) (547 ) Total purchase price $ 9,174 $ 1,229 $ 4,395 $ 36,246 At December 31, 2016 and 2015 , deferred cash obligations related to acquisitions completed in 2014 totaled $3.9 million and $6.2 million , respectively.

The decrease in this balance during 2016 is attributable to reimbursement payments received from the landlord related to completed leasehold improvements. The indemnification asset and the increase in inventory between the periods arose from our acquisition of NWP Services Corporation, which was completed in the first quarter of 2016 .

The gross amount of capitalized software development costs was $55.4 million and $41.2 million and was carried net of accumulated amortization of $19.8 million and $14.0 million at December 31, 2016 and 2015 , respectively. The weighted average amortization period for capitalized software development costs was 4.7 years at December 31, 2016 . During the years ended December 31, 2016 , 2015 , and 2014 , we capitalized $13.7 million , $10.5 million , and $10.9 million of software development costs, respectively. Amortization expense related to capitalized software development costs totaled $5.8 million , $3.3 million , and $1.7 million during the years ended December 31, 2016 , 2015 , and 2014 , respectively. We review in-progress software development projects on a periodic basis to ensure completion is assured and the development work will be placed into service as a new product or significant product enhancement. During the year ended December 31, 2015 , we identified certain projects for which software development work had ceased and it was determined the projects would be discontinued. Our analysis of the capitalized costs resulted in the conclusion that they had no value outside of the respective projects for which they were originally incurred. As a result, we recognized a loss of $1.4 million during the year ended December 31, 2015 , related to the disposal of these assets. During the years ended December 31, 2016 and 2015 , we modified or terminated certain operating lease agreements for office space prior to the end of the applicable lease term. We recognized an impairment charge of $1.5 million during the year ended December 31, 2015 , related to leasehold improvements associated with a modified lease. No impairments of leasehold improvements associated with a modified lease were identified during 2016 . Related to these lease modifications, we also disposed of fixed assets with a net carrying value of $0.6 million and $1.3 million , and recognized a net loss on disposal of $0.6 million and $0.2 million during 2016 and 2015 , respectively. The above loss and impairment charge are included in the line "General and administrative" in the accompanying Consolidated Statements of Operations.

The following table sets forth the estimated amortization of intangible assets for the years ending December 31, in thousands: 2017 $ 18,797 2018 13,380 2019 9,860 2020 8,159 2021 5,545 In March 2015, the Company completed the integration of the InstaManager and Kigo platforms into a single solution marketed under the Kigo name. Subsequent to this integration, the Company discontinued the use of the InstaManager trade name to market or identify the software. Due to this change in circumstance, the Company evaluated the InstaManager trade name for impairment and concluded an impairment in the amount of $0.5 million existed at March 31, 2015 . In connection with the preparation of the third quarter 2015 financial statements, the Company identified indicators requiring the assessment of certain indefinite-lived trade names for impairment, primarily associated with the Company's 2011 acquisition of MyNewPlace. Identified indicators included declines in actual and anticipated lead-generation revenues and a change in the Company's long-term marketing strategy. As a result, the Company analyzed these intangible assets and recorded a $20.3 million impairment charge during the third quarter of 2015, representing the amount by which the carrying value of the indefinite-lived trade names exceeded their estimated fair value. Given the change in the Company's long-term marketing strategy and anticipated use of the trade names, the remaining balance was reclassified to finite-lived intangible assets as of September 30, 2015 . The trade names were assigned an estimated useful life of seven years , amortized on a straight-line basis. The $3.7 million of net dispositions shown above reflect our sale of certain assets associated with our senior living referral services in the fourth quarter of 2016. Based on the status of the sale negotiations at the end of the third quarter, we determined there was a possibility that certain of the assets could be impaired and performed an impairment analysis. As a result of that analysis we recorded an impairment of the associated trade names at September 30, 2016 , in the amount of $0.8 million , the amount by which the carrying value of the trade names exceeded their estimated fair value on the date of analysis. The above impairment charges are included in "Impairment of identified intangible assets" in the accompanying Consolidated Statements of Operations. See Note 12 for discussion of the methodology and inputs utilized by the Company to estimate the fair value of these indefinite-lived trade names.

Debt Disclosure [Abstract]
Debt	Debt On September 30, 2014 , we entered into an agreement for a secured revolving credit facility (as amended by the Amendment discussed below, the “Credit Facility”) to refinance our outstanding revolving loans. The Credit Facility provides an aggregate principal amount of up to $200.0 million of revolving loans, with sublimits of $10.0 million for the issuance of letters of credit and $20.0 million for swingline loans ("Revolving Facility"). The Credit Facility also allowed us, subject to certain conditions, to request additional term loans or revolving commitments up to an aggregate principal amount of $150.0 million , plus an amount that would not cause our consolidated net leverage ratio, as defined below, to exceed 3.25 to 1.00 . At our option, amounts outstanding under the Credit Facility accrued interest at a per annum rate equal to either LIBOR, plus a margin ranging from 1.25% to 1.75% , or the Base Rate, plus a margin ranging from 0.25% to 0.75% ("Applicable Margin"). The base LIBOR rate is, at our discretion, equal to either one, two, three, or six month LIBOR. The Base Rate is defined as the greater of Wells Fargo's prime rate, the Federal Funds Rate plus 0.50% , or one month LIBOR plus 1.00% . In each case, the Applicable Margin is determined based upon our consolidated net leverage ratio. In February 2016 , we entered into an amendment to the Credit Facility (the “Amendment”). The Amendment provides for an incremental term loan in the amount of $125.0 million (“Term Loan”) that is coterminous with the existing Credit Facility, reducing the amount of additional term loans or revolving commitments available under the Credit Facility to $25.0 million , plus an amount that would not cause us to exceed the consolidated net leverage ratio limitation. Under the terms of the Amendment, an additional tier was added such that the Applicable Margin now ranges from 1.25% to 2.00% for LIBOR loans, and 0.25% to 1.00% for Base Rate loans. We incurred debt issuance costs in the amount of $0.7 million in conjunction with the execution of the Amendment. Revolving loans under the Credit Facility may be voluntarily prepaid and re-borrowed. Principal payments on the Term Loan are due in quarterly installments that began in June 2016 and such amounts may not be re-borrowed. Accumulated interest on amounts outstanding under the Credit Facility is due and payable quarterly, in arrears, for loans bearing interest at the Base Rate and at the end of the applicable interest period in the case of loans bearing interest at the adjusted LIBOR. All outstanding principal and accumulated interest is due upon the Credit Facility's maturity on September 30, 2019 . The Term Loan is subject to mandatory repayment requirements in the event of certain asset sales or if certain insurance or condemnation events occur, subject to customary reinvestment provisions. The Company may prepay the Term Loan in whole or in part at any time, without premium or penalty, with prepayment amounts to be applied to remaining scheduled principal amortization payments as specified by the Company. The Credit Facility is secured by substantially all of our assets, and certain of our existing and future material domestic subsidiaries are required to guarantee obligations under the Credit Facility. We are also required to comply with customary affirmative and negative covenants, as well as a consolidated net leverage ratio and a consolidated interest coverage ratio. The consolidated net leverage ratio, which is the ratio of funded indebtedness on the last day of each fiscal quarter to the four previous consecutive fiscal quarters' consolidated EBITDA, cannot be greater than 3.50 to 1.00 , provided that we can elect to increase the ratio to 3.75 to 1.00 for a specified period following a permitted acquisition. The Amendment permits the Company to elect to increase the maximum permitted consolidated net leverage ratio on a one-time basis to 4.00 to 1.00 following the issuance of convertible or high yield notes in an initial principal amount of at least $150.0 million . The consolidated interest coverage ratio, which is a ratio of our four previous fiscal consecutive quarters' consolidated EBITDA to our interest expense, cannot be less than 3.00 to 1.00 as of the last day of any fiscal quarter. As of December 31, 2016 , we were in compliance with the covenants under our Credit Facility. The Credit Facility contains customary events of default, subject to customary cure periods for certain defaults, that include, among others, non-payment defaults; covenant defaults; material judgment defaults; bankruptcy and insolvency defaults; cross-defaults to certain other material indebtedness; ERISA defaults; inaccuracy of representations and warranties; and a change in control default. In the event of a default on our Credit Facility, the obligations under the Credit Facility could be accelerated, the applicable interest rate under the Credit Facility could be increased, the loan commitments could be terminated, our subsidiaries that have guaranteed the Credit Facility could be required to pay the obligations in full, and our lenders would be permitted to exercise remedies with respect to all of the collateral that is securing the Credit Facility, including substantially all of our and our subsidiary guarantors’ assets. Any such default that is not cured or waived could have a material adverse effect on our liquidity and financial condition. Future maturities of principal under the Term Loan are as follows for the years ending December 31, in thousands: 2017 $ 5,469 2018 6,250 2019 110,918 $ 122,637 We had $122.6 million outstanding under our Term Loan at December 31, 2016 . As of December 31, 2016 , we had no balance outstanding under our Revolving Facility, and we had a $40.0 million outstanding balance as of December 31, 2015 . The weighted-average interest rate of short-term borrowings during the years ended December 31, 2016 and 2015 , was 1.75% and 1.58% , respectively. As of December 31, 2016 , $200.0 million was available under our Revolving Facility, of which $10.0 million was available for the issuance of letters of credit and $20.0 million for swingline loans. We had unamortized debt issuance costs of $1.3 million and $1.0 million at December 31, 2016 and 2015 , respectively. At December 31, 2016 , the Term Loan was carried net of unamortized debt issuance costs of $0.5 million in the accompanying Consolidated Balance Sheets. On March 31, 2016 , the Company entered into two interest rate swap agreements (“Swap Agreements”), which are designed to mitigate our exposure to interest rate risk associated with a portion of our variable rate debt. The Swap Agreements cover an aggregate notional amount of $75.0 million from March 2016 to September 2019 by replacing the obligation’s variable rate with a blended fixed rate of 0.89% . The Company designated the Swap Agreements as cash flow hedges of interest rate risk. See additional information related to the Swap Agreements at Note 14 . We entered into an amendment of the Credit Facility in February 2017 which, among other changes, provides for an incremental $200.0 million delayed draw term loan that is available to be drawn until May 31, 2017 , extends the maturity of the Credit Facility to February 24, 2022 , and amends the amortization schedule for the Term Loan. Under the amended amortization schedule, the Company will make quarterly principal payments of 0.6% of the Term Loan's and Delayed Draw Term Loan's respective outstanding balances beginning June 30, 2017 . The quarterly payment amounts increase to 1.3% of their respective outstanding balances beginning on June 30, 2018 , and to 2.5% beginning on June 30, 2020 . Any remaining principal balance on Term Loan and Delayed Draw Term Loan is due on the date of maturity, February 24, 2022 . With the new delayed draw term loan, the existing Term Loan, and the Revolving Facility, the Credit Facility now includes $522.6 million of drawn or available credit. See additional discussion of the amendment in Note 20 , Subsequent Events.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Expense	Stock-based Expense Our Amended and Restated 1998 Stock Incentive Plan (“Stock Incentive Plan”) provided for awards which could be granted in the form of incentive stock options, non-qualified stock options, restricted stock, stock appreciation rights, and performance restricted stock. In August 2010, we discontinued issuance of new awards under the Stock Incentive Plan and concurrently adopted the 2010 Equity Incentive Plan ("Equity Incentive Plan"). The Equity Incentive Plan, as amended, provides for awards which may be granted in the form of incentive stock options, non-statutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, and performance shares under substantially the same terms as the Stock Incentive Plan. We also grant awards to our directors in accordance with the Board of Directors Policy (“Board Plan”). Prior to 2010, these awards were generally in the form of stock options. Beginning in 2010, the awards granted to our directors are generally in the form of restricted stock. The awards granted to directors generally vest ratably over a period of four quarters; however, should a director leave the board, we have the right to repurchase shares as if the awards vested on a pro rata basis. In connection with our acquisition of Multifamily Technology Solutions, Inc. ("MTS"), on August 24, 2011, we assumed 349,693 non-qualified and incentive stock options granted from MTS’s 2005 Equity Incentive Plan (“MTS Plan”) for 96 employees. Assumed options were converted to equivalent stock-based awards of RealPage based on the ratio of our fair market value of stock to the fair market value of MTS’s stock on the acquisition date. The number of shares and ratio of exercise price to market price were equitably adjusted to preserve the intrinsic value of the awards as of immediately prior to the acquisition. The conversion was accounted for as a modification, which did not result in an incremental increase in the fair value of the assumed option awards. The majority of assumed options vest over a four -year period at a rate of 25% or 20% after one year and then monthly on a straight-line basis thereafter while others vest ratably over a four -year period. Options granted generally are exercisable up to ten years . No further options will be granted under the MTS Plan. Our board of directors periodically approves increases to the number of shares of common stock reserved for issuance under the Equity Incentive Plan. At December 31, 2016 and 2015 , there were 27,634,259 and 25,634,259 shares of the Company's common stock reserved for awards under the Equity Incentive Plan, respectively. The exercise of stock options and grants of restricted stock are fulfilled through the issuance of previously authorized but unissued common stock shares. Total compensation expense related to our stock-based expense plans was $36.9 million , $38.1 million , and $37.1 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. During the years ended December 31, 2016 , 2015 , and 2014 , we recognized a tax benefit of $13.9 million , $14.4 million , and $14.0 million , respectively. Total unrecognized compensation expense related to our stock-based expense plans was $42.9 million at December 31, 2016 , and is expected to be recognized over a weighted average period of 1.8 years. Cash proceeds related to stock-based expense transactions totaled $28.5 million , $12.1 million , and $9.9 million during the years ended December 31, 2016 , 2015 , and 2014 , respectively. Stock Option Awards Stock options granted prior to February 2014 generally vest over a period of sixteen quarters, with 75% vesting ratably over fifteen quarters and the remaining 25% vesting in the sixteenth quarter. Beginning in February 2014, stock options granted generally vest ratably over a period of twelve quarters. Expense is recognized over the requisite service period in a manner that reflects the vesting of the related awards. Awards under the plan generally expire ten years from the date of the grant. All outstanding options were granted at exercise prices equal to or exceeding our estimate of the fair market value of our common stock at the date of grant. The following table summarizes stock option transactions under our Stock Incentive Plan, Equity Incentive Plan, Board Plan, and MTS Plan: Number of Shares Range of Exercise Prices Weighted Average Exercise Price January 1, 2014 5,914,802 $ 0.91 – $ 29.50 $ 18.56 Granted 1,934,031 15.19 – 21.54 17.68 Exercised (907,765 ) 0.91 – 21.60 10.92 Forfeited/cancelled (1,336,894 ) 4.28 – 29.50 20.93 Expired (37,286 ) 19.78 – 24.64 24.02 Balance at December 31, 2014 5,566,888 0.91 – 29.50 18.89 Granted 2,434,198 18.79 – 23.10 19.81 Exercised (809,303 ) 0.91 – 21.60 14.97 Forfeited/cancelled (1,389,910 ) 5.04 – 29.50 20.54 Balance at December 31, 2015 5,801,873 0.91 – 29.50 19.43 Exercised (1,568,699 ) 1.68 – 27.18 18.16 Forfeited/cancelled (625,431 ) 4.28 – 29.50 21.77 Expired (654 ) 0.91 – 0.91 0.91 Balance at December 31, 2016 3,607,089 2.55 – 29.50 19.58 The below table provides information regarding outstanding stock options which were fully vested and expected to vest and exercisable options at December 31: 2016 2015 Options Fully Vested and Expected to Vest Options Exercisable Options Fully Vested and Expected to Vest Options Exercisable Number of options 3,606,462 2,477,474 5,795,711 2,843,655 Weighted-average remaining contractual term (in years) 6.5 5.9 7.5 6.4 Weighted-average exercise price $ 19.58 $ 19.24 $ 19.43 $ 18.67 Aggregate intrinsic value, in thousands $ 37,581 $ 26,659 $ 21,080 $ 13,316 The aggregate intrinsic value of options exercised during the years ended December 31, 2016 , 2015 , and 2014 , was $11.3 million , $5.0 million , and $8.5 million , respectively. The fair value of each stock option grant was estimated as of the date of grant using the Black Scholes option-pricing model with the following weighted-average assumptions and resulting weighted-average fair value per share for the years ended December 31, 2015 and 2014 .

This is the projected annual rate at which we expect awards to be forfeited in the future. We used a forfeiture rate of zero to value the awards granted during 2015 and 2014 due to the timing of when our shares vest and the expense is recorded. Expected volatility. Volatility is a measure of the amount by which a financial variable, such as a share price, has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. During 2015, we began estimating expected volatility based solely on the Company's historic and expected volatility. In previous years, we estimated expected volatility using a blend of the Company's historic and expected volatility and that of publicly traded peers. Dividend yield. This metric indicates how much the Company is expected to pay out in dividends relative to its share price during a period. We utilized a dividend yield of zero in estimating the fair value of stock options awarded in 2015 and 2014 , as we do not anticipate paying dividends in the foreseeable future. Restricted Stock Awards Restricted stock awards entitle the holder to receive shares of our common stock as the award vests. Grants of restricted stock are classified as time-based, market-based, or performance-based depending on the vesting criteria of the award. Time-based restricted stock awards: Time-based restricted stock awards granted prior to February 2014, generally vest ratably over sixteen quarters following the date of grant. Awards granted during 2014 and 2015, generally vest ratably over a period of twelve quarters beginning on the first day of the quarter immediately following the grant date. Beginning in 2016, awards granted generally vest ratably over a period of twelve quarters beginning on the first day of the second calendar quarter immediately following the grant date. The fair value of time-based restricted stock awards is based on the closing price of our common stock on the date of grant. Compensation expense for time-based restricted stock awards is recognized over the vesting period on a straight-line basis. During the years ended December 31, 2016 , 2015 , and 2014 , the Company issued time-based restricted shares with an aggregate grant-date fair value of $16.9 million , $21.5 million , and $23.3 million vested, respectively. A summary of time-based restricted stock award activity is presented in the table below. Number of Shares Weighted Average Grant-Date Fair Value Non-vested shares at January 1, 2014 2,090,803 $ 22.10 Granted 1,238,226 17.69 Vested (1,101,143 ) 21.18 Forfeited/cancelled (603,367 ) 20.36 Non-vested shares at December 31, 2014 1,624,519 20.01 Granted 913,077 19.84 Vested (1,077,102 ) 19.78 Forfeited/cancelled (391,788 ) 18.65 Non-vested shares at December 31, 2015 1,068,706 20.05 Granted 1,793,257 20.79 Vested (841,983 ) 20.14 Forfeited/cancelled (386,479 ) 20.21 Non-vested shares at December 31, 2016 1,633,501 20.78 Market-based restricted stock awards: Market-based restricted stock awards become eligible for vesting upon on the achievement of specific market-based conditions based on the per share price of the Company's common stock. Shares that become eligible to vest, if any, become Eligible Shares. Eligible Shares generally vest ratably over a period of four quarters, beginning on the first day of the quarter immediately after they become Eligible Shares. Vesting is conditional upon the recipient remaining a service provider, as defined in the plan document, to the Company through each applicable vesting date. A summary of market-based restricted stock award activity is presented in the table below. Number of Shares Weighted Average Grant-Date Fair Value Balance at January 1, 2014 — $ — Granted 520,000 11.26 Balance at December 31, 2014 520,000 11.26 Granted 691,165 11.59 Forfeited/cancelled (196,070 ) 9.39 Balance at December 31, 2015 1,015,095 11.85 Granted 794,025 13.58 Vested (51,250 ) 12.52 Forfeited/cancelled (193,710 ) 11.61 Balance at December 31, 2016 1,564,160 12.73 We estimate the fair value of market-based restricted stock awards using a discrete model to analyze the fair value of the subject shares. The discrete model utilizes multiple stock price-paths, through the use of Monte Carlo simulation, which are then analyzed to determine the fair value of the subject shares. The weighted average of assumptions used to value awards granted during 2016 and 2015 , were as follows: 2016 2015 2014 Risk-free interest rate 1.1 % 1.1 % 1.1 % Expected volatility 41.5 % 38.7 % 43.6 % Risk-free interest rate. We estimated the risk-free rate from the three year U.S. Treasury strip note yield curve as of the valuation date. Expected volatility. Similar to the methodology for stock options described above, the Company now estimates expected volatility based solely on the Company's historic and expected volatility rate. In previous years, we estimated expected volatility using a blend of the Company's historic and expected volatility and that of publicly traded peers. Expense related to the market-based restricted stock awards is recognized over the requisite service period using the graded-vesting attribution method. The requisite service period is a measure of the expected time to achieve the specified market condition plus the time-based vesting period. The expected time to achieve the market condition is estimated utilizing a Monte Carlo simulation, considering only those stock price-paths in which the market condition was achieved. The estimated requisite service period for market-based restricted stock shares issued in 2016 ranged from seven to nine quarters. Market-based restricted stock awards granted in 2015 had requisite service periods ranging between five to eleven quarters. Performance-based restricted stock awards: The Company has also granted performance-based restricted stock awards. These awards become eligible to vest if specified performance targets are achieved prior to the performance deadline. Subsequent to achievement of the performance target the awards vest quarterly over a one-year service period. The performance-based restricted stock awards are forfeited if the performance targets are not achieved prior to the performance deadline. Compensation expense for performance-based restricted stock awards is recognized on a straight-line basis over the requisite service period, which includes both the performance period and the subsequent time-based vesting period. Expense is only recognized if it is determined that achievement of the performance condition is probable. The fair value of performance-based restricted stock awards is based on the closing price of our common stock on the date of grant. A summary of performance-based restricted stock award activity is presented in the table below: Number of Shares Weighted Average Grant-Date Fair Value Non-vested shares at January 1, 2014 70,000 $ 18.10 Forfeited/cancelled (70,000 ) 18.10 Non-vested shares at December 31, 2014 — — Granted 20,000 18.79 Non-vested shares at December 31, 2015 20,000 18.79 Forfeited/cancelled (20,000 ) 18.79 Non-vested shares at December 31, 2016 — —

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Lease Commitments The Company leases office facilities and equipment for various terms under long-term, non-cancellable operating lease agreements. The leases expire at various dates through 2028 and provide for renewal options. The agreements generally require the Company to pay for executory costs such as real estate taxes, insurance, and repairs. In connection with our 2016 acquisitions, the Company assumed non-cancellable operating leases for equipment and office space. Office leases assumed include locations in Costa Mesa, California; Tampa, Florida; Ann Arbor, Michigan; and Bloomington, Minnesota. The office leases expire at various dates through 2020 and have terms substantially similar to our other office leasing arrangements. Equipment leases assumed by the Company include leases for equipment used in the general operation of the business and have lease terms expiring through 2020 . These agreements have terms substantially similar to our other equipment leasing arrangements. In May 2015 , the Company entered into a lease agreement for office space located in Richardson, Texas to serve as our new corporate headquarters and data center. The lease is for a term of twelve years , beginning in 2016, and includes optional extension periods. The lease agreement contains provisions for rent escalations over the term of the lease and leasehold improvement incentives. In July 2015 , the Company entered into an amendment to the lease agreement which increased the amount of leased space. The lease was again amended in July 2016 , which permitted an increase in our tenant improvement allowance. We completed the move of our corporate headquarters and data center to this new facility in the third quarter of 2016. Our lease for our previous corporate headquarters expired in December 2016. At December 31, 2016 and 2015 , we had a receivable for incentives under this lease of zero and $19.4 million , respectively. The decrease in the lease incentives receivable balance between the periods is attributable to reimbursements received from the landlord for completed leasehold improvements. The lease receivable is included in "Other current assets" in the accompanying Consolidated Balance Sheets. Rent expense was $14.7 million , $10.9 million , and $11.1 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. Minimum annual rental commitments under non-cancellable operating leases were as follows at December 31, 2016 : Minimum Lease Commitments (in thousands) 2017 $ 11,195 2018 11,160 2019 9,864 2020 7,911 2021 7,271 Thereafter 48,640 $ 96,041 Guarantor Arrangements We have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is or was serving at our request in such capacity. The term of the indemnification period is for the officer or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have a director and officer insurance policy that limits our exposure and enables us to recover a portion of any future amounts paid. As a result of our insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal. Accordingly, we had no liabilities recorded for these agreements as of December 31, 2016 or 2015 . In the ordinary course of our business, we include standard indemnification provisions in our agreements with our clients. Pursuant to these provisions, we indemnify our clients for losses suffered or incurred in connection with third-party claims that our products infringed upon any U.S. patent, copyright, trademark, or other intellectual property right. Where applicable, we generally limit such infringement indemnities to those claims directed solely to our products and not in combination with other software or products. With respect to our products, we also generally reserve the right to resolve such claims by designing a non-infringing alternative, by obtaining a license on reasonable terms, or by terminating our relationship with the client and refunding the client’s fees. The potential amount of future payments to defend lawsuits or settle indemnified claims under these indemnification provisions is unlimited in certain agreements; however, we believe the estimated fair value of these indemnification provisions is minimal, and, accordingly, we had no liabilities recorded for these agreements as of December 31, 2016 or 2015 . Litigation From time to time, in the normal course of our business, we are a party to litigation matters and claims. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict and our view of these matters may change in the future as the litigation and events related thereto unfold. We expense legal fees as incurred. Insurance recoveries associated with legal costs incurred are recorded when they are deemed probable of recovery. In March 2015, we were named in a purported class action lawsuit in the United States District Court for the Eastern District of Pennsylvania, styled Stokes v. RealPage, Inc. , Case No. 2:15-cv-01520. The claims in this purported class action relate to alleged violations of the Fair Credit Reporting Act (“FCRA”) in connection with background screens of prospective tenants of our clients. On January 25, 2016, the court entered an order placing the case on hold until the United States Supreme Court issued its decision in Spokeo, Inc. v. Robins, which case addressed issues related to standing to bring claims related to the FCRA. On May 16, 2016, the U.S. Supreme Court issued its opinion in the Spokeo litigation, vacating the decision of the United States Court of Appeals for the Ninth Circuit, and remanding the case for further consideration by the U.S. Court of Appeals. Following the Supreme Court’s decision in Spokeo, the judge in the Stokes case lifted the stay. On June 24, 2016, we filed a motion to dismiss certain claims made in the case based upon the Spokeo decision. On October 19, 2016, the U.S. District Court denied the motion to dismiss. We intend to defend this case vigorously. In November 2014, we were named in a purported class action lawsuit in the United States District Court for the Eastern District of Virginia, styled Jenkins v. RealPage, Inc. , Case No. 3:14cv758. The claims in this purported class action relate to alleged violations of the FCRA in connection with background screens of prospective tenants of our clients. This case has since been transferred to the United States District Court for the Eastern District of Pennsylvania. On January 25, 2016, the court entered an order placing the case on hold until the United States Supreme Court issued its decision in the Spokeo case. Following the Supreme Court’s decision in Spokeo , the judge in the Jenkins case lifted the stay. On June 24, 2016, we filed a motion to dismiss certain claims made in the case based upon the Spokeo decision. On October 19, 2016, the U.S. District Court denied the motion to dismiss. We intend to defend this case vigorously. On February 23, 2015, we received from the Federal Trade Commission ("FTC") a Civil Investigative Demand consisting of interrogatories and a request to produce documents relating to our compliance with the FCRA. We have responded to the request and requests for additional information by the FTC. At this time, we do not have sufficient information to evaluate the likelihood or merits of any potential enforcement action, or to predict the outcome or costs of responding to, or the costs, if any, of resolving this investigation. During 2014, we expensed $4.7 million , inclusive of the settlements and other associated costs, related to litigation settled during that period. The litigation related to reimbursement claims made against us, each by a primary and an excess layer errors and omissions insurance carrier. The carriers were seeking reimbursement of claims formerly funded by them relating to a litigation matter settled in 2012. At December 31, 2016 and 2015 , we had accrued amounts for estimated settlement losses related to legal matters. The Company does not believe there is a reasonable possibility that a material loss exceeding amounts already recognized may have been incurred as of the date of the balance sheets presented herein. We are involved in other litigation matters not described above that are not likely to be material either individually or in the aggregate based on information available at this time. Our view of these matters may change as the litigation and events related thereto unfold.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	Net Income (Loss) per Share Basic net income (loss) per share was computed by dividing the net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share was computed by using the weighted average number of common shares outstanding, including potential dilutive shares of common stock assuming the dilutive effect of outstanding stock options and restricted stock using the treasury stock method. Weighted average shares from common share equivalents in the amount of 220,473 , 912,257 , and 1,273,889 were excluded from the dilutive shares outstanding because their effect was anti-dilutive for the years ended December 31, 2016 , 2015 , and 2014 , respectively. The following table presents the calculation of basic and diluted net income (loss) per share attributable to common stockholders: Year Ended December 31, 2016 2015 2014 (in thousands, except per share amounts) Numerator: Net income (loss) $ 16,650 $ (9,218 ) $ (10,274 ) Denominator: Basic: Weighted average shares used in computing basic net income (loss) per share: 76,854 76,689 76,991 Diluted: Weighted average shares used in computing basic net income (loss) per share: 76,854 76,689 76,991 Add weighted average effect of dilutive securities: Stock options and restricted stock 989 — — Weighted average shares used in computing diluted net income (loss) per share: 77,843 76,689 76,991 Net income (loss) per share attributable to common stockholders: Basic $ 0.22 $ (0.12 ) $ (0.13 ) Diluted $ 0.21 $ (0.12 ) $ (0.13 )

Significant components of our deferred tax assets and liabilities are as follows: December 31, 2016 2015 (in thousands) Deferred tax assets: Reserves, deferred revenue and accrued liabilities $ 22,518 $ 8,107 Stock-based expense 17,184 15,112 Net operating loss carryforwards and tax credits 16,193 13,733 Total deferred tax assets 55,895 36,952 Deferred tax liabilities: Property, equipment, and software (25,626 ) (10,041 ) Intangible assets (10,514 ) (11,563 ) Other (4,090 ) (3,297 ) Total deferred tax liabilities (40,230 ) (24,901 ) Net deferred tax assets $ 15,665 $ 12,051 We periodically evaluate the realizability of our deferred tax assets. If we determine that it is more likely than not that all or a portion of such assets are not realizable, we provide a valuation allowance against the assets. We determined that no valuation allowance was required at December 31, 2016 or 2015 . The determination of the level of valuation allowance, if any, required at any time is based on a forecast of future taxable income that includes many judgments and assumptions. Accordingly, it is at least reasonably possible that future changes in one or more assumptions may lead to a change in judgment regarding the level of valuation allowance required in future periods. The acquisition of the stock of NWP in March 2016 resulted in an additional net deferred tax asset of $11.2 million . This net asset includes approximately $9.6 million related to additional deferred tax assets from federal NOLs and $0.3 million related to state NOLs; $3.3 million related to property, equipment, and software; inventory and accrued expenses; and $2.0 million of deferred tax liability related to intangibles. The acquisition of the stock of AssetEye in May 2016 resulted in additional deferred tax liabilities of $0.9 million related to intangibles. The company had no federal or state NOL carryovers. Our tax-effected federal and state NOL carryforwards of $13.4 million and $1.5 million , respectively, and our combined federal and state tax credits of $1.3 million comprise a major component of our deferred tax assets. If not used, the underlying gross federal NOLs totaling $38.3 million will begin to expire in 2022 and the underlying state NOLs totaling $19.4 million will begin to expire in 2017 , with less than $5.0 million expiring in the next five years . Approximately $0.1 million of our credits expire in 2026 , and the balance has no expiration date. In addition to the NOLs just described, we also have gross federal and state NOLs of $120.6 million and $41.2 million , respectively, for which we have not recognized benefit for financial reporting purposes. These unrecognized NOLs result from the excess of stock-based compensation deductions for tax return purposes over the expense recognized for financial reporting purposes that has not yet been realized in actual tax returns. The benefit from these excess stock compensation federal and state NOLs of approximately $42.2 million and $1.9 million , respectively, less any valuation reserve determined to be required, will be credited to retained earnings upon the Company's adoption of ASU 2016-09 effective January 1, 2017. We use the "with-and-without" method, as described in ASC 740, for purposes of determining when excess tax benefits have been realized. In 2016 and 2015 , we recognized excess stock compensation benefits from NOLs of $3.1 million and $0.4 million , respectively. Net operating losses that we have generated are not currently subject to the Section 382 limitation; however, $37.6 million of net operating losses generated by our subsidiaries prior to our acquisition of them are subject to the Section 382 limitation. The limitation on these pre-acquisition net operating loss carryforwards will fully expire in 2035. A cumulative change in ownership among material shareholders, as defined in Section 382 of the Internal Revenue Code, during a three years period also may limit utilization of the federal net operating loss carryforwards. Our subsidiary in Hyderabad, India benefited from a tax holiday granted under the Software Technology Parks of India program that began upon commencement of business operations in 2008 and continued through March 31, 2011 . During this holiday period, we were required to pay a minimum alternative tax which was available to reduce our post-holiday tax liability. Effective July 8, 2013 , this subsidiary began to benefit from a tax holiday under the Special Economic Zone program. This benefit was initially granted for a five years period and applies to a portion of our operations in this location. The expiration of this tax holiday will increase our effective income tax rate. As a result of this tax holiday, the Company realized tax savings of $0.2 million , $0.4 million , and $0.2 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. Our subsidiary in Manila, Philippines has benefited from Philippines income tax holiday incentives pursuant to registration with the Philippine Economic Zone Authority ("PEZA"). We have four PEZA projects that have their own income tax holiday, and applications had to be made for each project. Each PEZA project has an income tax holiday that extends past December 31, 2016 , except for one that expired on November 30, 2016 . This project application was not renewed; therefore, we have to pay Philippine income tax on the net income for the month of December 2016. The expiration of this tax holiday will increase our effective tax rate in 2017 approximately 0.2% . Tax savings realized under the Philippine tax holiday incentives were $0.4 million , $0.3 million , and $0.2 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. We have recognized no provision for U.S federal and state income taxes on undistributed earnings of our foreign subsidiaries totaling approximately $9.5 million as such earnings are expected to be reinvested and are considered permanent in duration. If these earnings were ultimately distributed to the U.S. in the form of dividends or otherwise, or if the shares of the subsidiaries were sold or transferred, we would likely be subject to additional U.S. income taxes, net of the impact of any available foreign tax credits of up to $2.4 million . Uncertain Tax Positions At December 31, 2016 and 2015 , we had no unrecognized tax benefits. Our policy is to include interest and penalties related to unrecognized income tax benefits in income tax expense, and as of December 31, 2016 and 2015 , there were no accrued interest and penalties. We file consolidated and separate tax returns in the U.S. federal jurisdiction and five foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations for years before 2013 and are no longer subject to state and local income tax examinations by tax authorities for years before 2012 ; however, net operating losses from all years continue to be subject to examinations and adjustments for at least three years following the year in which the attributes are used. Our subsidiary, RealPage India Private Limited ("RealPage India"), is currently undergoing an income tax examination for the fiscal years beginning April 1, 2011 and April 1, 2012. The India income tax authorities have assessed RealPage India additional tax and interest of $0.2 million in total for both years. We believe the assessments are incorrect and plan to appeal the decision to the India Commissioner of Income Tax. RealPage India is also under audit for the financial year beginning April 1, 2013, but no assessment has been made at this time. In July 2015, the Company filed amended 2012 and 2013 income tax returns for selected states to correct certain items that were improperly deducted, as determined by the Company subsequent to the initial filings. The primary effect of the amended returns was an immaterial increase in our current state income tax liability and a reduction of our state net operating loss deferred tax asset, net of federal benefit, of approximately $0.6 million .

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2016
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company records certain financial liabilities at fair value on a recurring basis. The Company determines fair values based on the price it would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The prescribed fair value hierarchy is as follows: Level 1 - Inputs are quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs are quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable, and market-corroborated inputs which are derived principally from or corroborated by observable market data. Level 3 - Inputs are derived from valuation techniques in which one or more of the significant inputs or value drivers are unobservable. The categorization of an asset or liability within the fair value hierarchy is based on the inputs described above and does not necessarily correspond to the Company’s perceived risk of that asset or liability. Moreover, the methods used by the Company may produce a fair value calculation that is not indicative of the net realizable value or reflective of future fair values. Furthermore, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments and non-financial assets and liabilities could result in a different fair value measurement at the reporting date. Assets and liabilities measured at fair value on a recurring basis: Interest rate swap agreements: The fair value of the Company’s interest rate derivatives are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivatives. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparties. 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 swap valuation in its entirety is classified in Level 2 of the fair value hierarchy. Contingent consideration obligations: Contingent consideration obligations consist of potential obligations related to our acquisition activity. The amount to be paid under these obligations is contingent upon the achievement of stipulated operational or financial targets by the business subsequent to acquisition. The fair value of contingent consideration obligations is estimated using a probability weighted discount model which considers the achievement of the conditions upon which the respective contingent obligation is dependent. The probability of achieving the specified conditions is assessed by applying a Monte Carlo weighted-average model. Inputs into the valuation model include a discount rate specific to the acquired entity, a measure of the estimated volatility, and the risk free rate of return. In addition to the inputs described above, the fair value estimates consider the projected future operating or financial results for the factor upon which the respective contingent obligation is dependent. The fair value estimates are generally sensitive to changes in these projections. We develop the projected future operating results based on an analysis of historical results, market conditions, and the expected impact of anticipated changes in our overall business and/or product strategies. Significant unobservable inputs used in the contingent consideration fair value measurements included the following at December 31, 2016 and 2015 : 2016 2015 Discount rates 14.8 - 27.8% 15.8 - 60.0% Volatility rates 29.9% 37.0 - 53.5% Risk free rate of return 0.7% 0.5 - 0.9% The following tables disclose the assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015 , by the fair value hierarchy levels as described above: Fair value at December 31, 2016 Total Level 1 Level 2 Level 3 (in thousands) Assets: Interest rate swap agreements $ 1,098 $ — $ 1,098 $ — Liabilities: Contingent consideration related to the acquisition of: Indatus 2 — — 2 AssetEye 539 — — 539 Total liabilities measured at fair value $ 541 $ — $ — $ 541 Fair value at December 31, 2015 Total Level 1 Level 2 Level 3 (in thousands) Liabilities: Contingent consideration related to the acquisition of: Indatus $ 814 $ — $ — $ 814 VRX 27 — — 27 Total liabilities measured at fair value $ 841 $ — $ — $ 841 There were no assets measured at fair value on a recurring basis at December 31, 2015 . There were no transfers between Level 1 and Level 2, or between Level 2 and Level 3 measurements during the years ended December 31, 2016 and 2015 . Changes in the fair value of Level 3 measurements for the reporting periods were as follows during the years ended December 31, 2016 and 2015 , in thousands: Balance at January 1, 2015 $ 4,150 Initial contingent consideration 1,414 Settlements through cash payments (1,179 ) Net gain on change in fair value (3,544 ) Balance at December 31, 2015 841 Initial contingent consideration 245 Net gain on change in fair value (545 ) Balance at December 31, 2016 $ 541 Gains and losses resulting from changes in the fair value of the above liabilities are included in "General and administrative" expense in the accompanying Consolidated Statements of Operations. Assets and liabilities measured at fair value on a non-recurring basis: During 2015, the Company identified triggering events which required the assessment of impairment for certain trade names related to prior acquisitions. The fair value of the trade names was determined through an income approach utilizing projected discounted cash flows. This method is consistent with the method the Company has employed in prior periods to value other indefinite-lived assets. Impairments of the trade names were determined by comparing the estimated fair value to the related carrying value. The inputs utilized in the discounted cash flow analysis are classified as Level 3 inputs within the fair value hierarchy. Significant unobservable inputs used in deriving the fair value included the royalty rate applied to the projected revenue stream and the discount rate used to determine the present value of the estimated future cash flows. Through the application of this approach, we concluded the aggregate fair value of the trade names was $5.1 million at September 30, 2015. The Company believes that the method used to determine the fair value of the assets was reasonable. In October 2016, the Company entered into an agreement with A Place for Mom whereby we sold certain assets associated with our senior living referral services, including certain indefinite-lived trade names. Based on the status of the negotiations, we concluded there was a possibility that the negotiated assets could be impaired and performed an impairment analysis as of September 30, 2016. We estimated the aggregate fair value of the negotiated assets to be $5.0 million at September 30, 2016, based on the price at which they were sold in October 2016 in an arms-length transaction with an unrelated party. The method utilized incorporated significant unobservable inputs and the Company concluded that the measurement should be classified within Level 3. There were no liabilities measured at fair value on a non-recurring basis at December 31, 2016 and 2015 . Financial Instruments The financial assets and liabilities that are not measured at fair value in our Consolidated Balance Sheets include cash and cash equivalents, restricted cash, accounts receivable, cost-method investments, accounts payable and accrued expenses, acquisition-related deferred cash obligations, and obligations under the Credit Facility. The carrying values of cash and cash equivalents; restricted cash; accounts receivable; and accounts payable and accrued expenses reported in our Condensed Consolidated Balance Sheets approximates fair value due to the short term nature of these instruments. Acquisition-related deferred cash obligations are recorded on the date of acquisition at their estimated fair value, based on the present value of the anticipated future cash flows. The difference between the amount of the deferred cash obligation to be paid and its estimated fair value on the date of acquisition is accreted over the obligation period. As a result, the carrying value of acquisition-related deferred cash obligations approximates their fair value. The Company concluded that the fair value estimates described above should be categorized within Level 3. Due to its short-term nature and market-indexed interest rates, we concluded that the carrying value of the Revolving Facility approximates its fair value at December 31, 2015. The estimated fair value of our obligations under the Term Loan was $122.5 million at December 31, 2016 . The fair value of the Term Loan was estimated by discounting future cash flows using prevailing market interest rates on debt with similar creditworthiness, terms, and maturities. The Company concluded that the fair value of the Company's debt should be categorized within Level 2.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments On March 31, 2016 , the Company entered into two Swap Agreements, which are designed to mitigate our exposure to interest rate risk associated with a portion of our variable rate debt. The Swap Agreements cover an aggregate notional amount of $75.0 million from March 2016 to September 2019 by replacing the obligation’s variable rate with a blended fixed rate of 0.89% . The Company designated the Swap Agreements as cash flow hedges of interest rate risk. The effective portion of changes in the fair value of Swap Agreements is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in the fair value of the Swap Agreements is recognized directly in earnings. During the fiscal year ended December 31, 2016 , we recognized a gain on the ineffective portion of the Swap Agreement of $0.2 million . Amounts reported in accumulated other comprehensive loss related to the Swap Agreements will be reclassified to interest expense as interest payments are made on our variable-rate debt. The Company estimates that an additional $0.1 million will be reclassified as a decrease to interest expense during the twelve-month period ending December 31, 2017 .

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Acquisition Activity In January 2017 , the Company acquired substantially all of the assets of Axiometrics LLC ("Axiometrics"), a leading provider of data and analytics services for the multifamily industry. This acquisition expanded our multifamily data analytics platform and will be integrated with MPF Research, our market research database. Purchase consideration was comprised of a cash payment at closing of $67.5 million , a deferred cash obligation of up to $7.5 million , and contingent cash payments of up to $5.0 million . The deferred cash obligation serves as security for the benefit of the Company against the sellers' indemnification obligations. Subject to any indemnification claims made, the deferred cash obligation will be released over a period of 24 months following the acquisition date. Payment of the contingent cash obligation is dependent upon the achievement of certain revenue targets during the twelve months period ending December 31, 2018 . In February 2017 , we entered into an agreement to acquire Lease Rent Options ("LRO") and related assets from The Rainmaker Group Holdings, Inc. The acquisition of LRO will extend our revenue management footprint, augment our repository of real-time lease transaction data, and increase our data science talent and capabilities. We expect the acquisition of LRO to increase the market penetration of our YieldStar solution and drive additional revenue growth in our asset optimization solutions. Pursuant to the asset purchase agreement, purchase consideration will be comprised of a cash payment at closing of approximately $298.5 million , subject to reduction for outstanding indebtedness, unpaid transaction expenses and a working capital adjustment, and a deferred cash obligation of up to $1.5 million . The deferred cash obligation serves as security for the benefit of the Company against the sellers' indemnification obligations. Subject to any indemnification claims made, the deferred cash obligation will be released approximately twelve months following the acquisition date. The completion of the acquisition remains subject to certain standard conditions, and is expected to close during the second quarter of 2017 . Due to the timing of the acquisitions, certain disclosures required by ASC 805, including the allocation of the purchase price, have been omitted because the initial accounting for the business combinations was incomplete as of the filing date of this report. Such information will be included in the Company's subsequent Form 10-Q. Amendment of the Credit Facility In February 2017 , the Company entered into the Third Amendment to Credit Agreement and Incremental Amendment ("Third Amendment") to the Credit Facility with each of the lenders party thereto and Wells Fargo Bank, National Association, as the administrative agent. The Third Amendment modifies certain terms of the Credit Facility to, among other things, provide for an incremental $200.0 million delayed draw term loan ("Delayed Draw Term Loan") that is available to be drawn until May 31, 2017 , extend the maturity of the Credit Facility to February 24, 2022 , and amend the amortization schedule for the Term Loan. Under the amended amortization schedule, the Company will make quarterly principal payments of 0.6% of the Term Loan's and Delayed Draw Term Loan's respective outstanding balances beginning June 30, 2017 . The quarterly payment amounts increase to 1.3% of their respective outstanding balances beginning on June 30, 2018 , and to 2.5% beginning on June 30, 2020 . Any remaining principal balance on Term Loan and Delayed Draw Term Loan is due on the date of maturity, February 24, 2022 . With the new Delayed Draw Term Loan, the existing Term Loan, and the Revolving Facility, the Credit Facility now includes $522.6 million of drawn or available credit. Except as amended, all of the existing terms of the Credit Facility remain in effect. All of the obligations under the Credit Facility, including the Delayed Draw Term Loan once drawn, are secured by substantially all of the Company's assets and by its existing and future domestic subsidiaries, except certain excluded subsidiaries, as provided in the Credit Facility. Proceeds from the Delayed Draw Term Loan will be used to finance our anticipated acquisition of LRO.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements and footnotes have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements include the accounts of RealPage, Inc. and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Segment and Geographic Information	Segment and Geographic Information Our chief operating decision maker is our Chief Executive Officer, who reviews financial information presented on a company-wide basis. As a result, we determined that the Company has a single reporting segment and operating unit structure.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires our management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the allowance for doubtful accounts; the useful lives of intangible assets and the recoverability or impairment of tangible and intangible asset values; fair value measurements; contingent commissions related to the sale of insurance products; purchase accounting allocations and contingent consideration; revenue and deferred revenue and related reserves; stock-based expense; and our effective income tax rate and the recoverability of deferred tax assets, which are based upon our expectations of future taxable income and allowable deductions. Actual results could differ from these estimates. The Company is self-insured for the cost of claims made under its employee medical programs. These costs include an estimate for expected settlements of pending claims and an estimate for claims incurred but not reported. These significant estimates are based on management's assessment of outstanding claims, historical analyses, and current payment trends.
Concentrations of Credit Risk	Concentrations of Credit Risk Our cash accounts are maintained at various financial institutions and may, from time to time, exceed federally insured limits. The Company has not experienced any losses in such accounts. Concentrations of credit risk with respect to accounts receivable result from substantially all of our clients being in the multifamily rental housing market. Our clients, however, are dispersed across different geographic areas. We do not require collateral from clients. We maintain an allowance for doubtful accounts based upon the expected collectability of accounts receivable.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with a maturity date, when purchased, of three months or less to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash consists of cash collected from tenants that will be remitted primarily to our clients.
Accounts Receivable	Accounts Receivable Accounts receivable primarily represent trade receivables from clients that we present net of an allowance for doubtful accounts. For several of our solutions, we invoice clients prior to the period in which service is provided. For certain transactions, we have met the requirements to recognize revenue in advance of invoicing the client. In these instances, we record unbilled receivables for the amount that will be due from the client upon invoicing. We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of clients to make required payments, or the client canceling prior to the service being rendered. As a result, a portion of our allowance is for services not yet rendered and, therefore, classified as an offset to deferred revenue. In evaluating the sufficiency of the allowance for doubtful accounts we consider the current financial condition of the client, the specific details of the client account, the age of the outstanding balance, the current economic environment, and historical credit trends. Any change in the assumptions used in analyzing a specific account receivable might result in an additional allowance for doubtful accounts being recognized in the period in which the change occurs. Accounts receivable are written off upon determination of non-collectability following established Company policies based on the aging from the accounts receivable invoice date. In the case of balances relating to services not yet rendered, the balance is written off when the client cancels the service or when we determine that the invoiced service will no longer be provided, whichever occurs first. During the years ended December 31, 2016 , 2015 , and 2014 , we incurred bad debt expense of $2.4 million , $2.0 million , and $1.5 million , respectively. Accounts receivable includes commissions due to the Company related to the sale of insurance products to individuals and commissions which are contingent based upon the activity in the underlying policies. Contingent commissions are determined based on a calculation that considers earned agent commissions, a percent of premium retained by our underwriting partner, incurred losses, and profit retained by our underwriting partner during the time period. Contingent commissions receivables are recorded at their estimated net realizable value, based on estimates and considerations which include, but are not limited to, the historical and projected loss rates incurred by the underlying policies.
Inventory	Inventory Inventories are stated at the lower of net realizable value or cost, determined on a first-in, first-out basis. The Company establishes inventory allowances for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated realizable values based on assumptions about forecasted demand, open purchase commitments, and market conditions. Inventories consist primarily of meters, including subcontract labor costs on contracts in progress.
Property, Equipment and Software	Property, Equipment, and Software Property, equipment, and software are recorded at cost less accumulated depreciation and amortization, which are computed using the straight-line method over the following estimated useful lives: Data processing and communications equipment 3 - 5 years Furniture, fixtures, and other equipment 3 - 5 years Software 3 - 5 years Software includes both purchased and internally developed software. Leasehold improvements are depreciated over the shorter of the lease term or twelve years . Gains and losses from asset disposals are included in the line "General and administrative" in the Consolidated Statements of Operations.
Capitalized Product Development Costs	Capitalized Product Development Costs We capitalize specific product development costs, including costs to develop software products or the software components of our solutions to be marketed to external users, as well as software programs to be used solely to meet our internal needs. The costs incurred in the preliminary stages of development related to research, project planning, training, maintenance, general and administrative activities, and overhead costs are expensed as incurred. The costs of relatively minor upgrades and enhancements to the software are also expensed as incurred. Once an application has reached the development stage, internal and external costs incurred in the performance of application development stage activities, including costs of materials, services, and payroll and payroll-related costs for employees, are capitalized, if direct and incremental, until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing. We also capitalize costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Capitalized costs are recorded as part of property, equipment, and software. Internal use software is amortized on a straight-line basis over its estimated useful life, generally three to five years . Our management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
Impairment of Long-Lived Assets	We test goodwill and identified intangible assets with indefinite lives for impairment separately on an annual basis in the fourth quarter of each year. Additionally, we test these assets in the interim if events and circumstances indicate they may be impaired. The events and circumstances that we consider include, but are not limited to, significant under-performance relative to current and historical or projected future operating results and significant changes in our overall business and/or product strategies. If an event or circumstance occurs that would cause us to revise our estimates and assumptions used in analyzing the value of our goodwill and identified intangible assets with indefinite lives, the revision could result in a non-cash impairment charge that could have a material impact on our financial results. We evaluate impairment of goodwill by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the two-step goodwill impairment test. The first step involves a comparison of the fair value of a reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step involves a comparison of the implied fair value and carrying amount of the goodwill of that reporting unit to determine the impairment charge, if any. We quantitatively evaluate identified intangible assets with indefinite lives by estimating the fair value of those assets based on estimated future earnings derived from the assets using the income approach model. Assets with indefinite lives that have been determined to be inseparable due to their interchangeable use are grouped into single units of accounting for purposes of testing for impairment. If the carrying amount of an identified intangible asset with an indefinite life exceeds its fair value, we would recognize an impairment loss equal to the excess of carrying value over fair value.
Business Combinations	Business Combinations The Company applies the guidance contained in ASC Topic 805, Business Combinations (“ASC 805”) in determining whether an acquisition transaction constitutes a business combination. ASC 805 defines a business as consisting of inputs and processes applied to those inputs that have the ability to create outputs. The acquisition transactions in Note 3 were determined to constitute business combinations and were accounted for under ASC 805. Purchase consideration includes assets transferred, liabilities incurred, and/or equity interests issued by us, all of which are measured at their fair value as of the date of acquisition. Our business combination transactions may be structured to include an up-front cash payment and deferred and/or contingent cash payments to be made at specified dates subsequent to the date of acquisition. Deferred cash payments are included in the acquisition consideration based on their fair value as of the acquisition date. The fair value of these obligations is estimated based on the present value, as of the date of acquisition, of the anticipated future payments. The future payments are discounted using a rate that considers an estimate of the return expected by a market-participant and a measurement of the risk inherent in the cash flows, among other inputs. Deferred cash payments are generally subject to adjustments specified in the underlying purchase agreement related to the seller’s indemnification obligations. Contingent cash payments are obligations to make future cash payments to the seller, the payment of which is contingent upon the achievement of stipulated operational or financial targets in the post-acquisition period. Contingent cash payments are included in the purchase consideration at their fair value as of the acquisition date. The fair value of these payments is estimated using a probability weighted discount model based on the achievement of the specified targets. The fair value of these liabilities is re-evaluated on a quarterly basis, and any change is reflected in the line “General and administrative” in the accompanying Consolidated Statements of Operations. These estimates are inherently uncertain and unpredictable. Unanticipated events and circumstances may occur that would affect the accuracy or validity of these estimates. The total purchase consideration is allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess consideration is classified as goodwill. Acquired intangibles are recorded at their estimated fair value based on the income approach using market-based estimates. Acquired intangibles generally include developed product technologies, which are amortized over their useful life on a straight-line basis, and client relationships, which are amortized over their useful life proportionately to the expected discounted cash flows derived from the asset. When trade names acquired are not classified as indefinite-lived, they are amortized on a straight-line basis over their expected useful life. Acquisition costs are expensed as incurred and are included in the line “General and administrative” in the accompanying Consolidated Statements of Operations. We include the results of operations from acquired businesses in our consolidated financial statements from the effective date of the acquisition. Purchase Price Allocation The estimated fair values of assets acquired and liabilities assumed presented below are provisional and are based on the information available as of the acquisition date. We believe that this information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed, but the Company is awaiting additional information necessary to finalize those values. Therefore, the provisional measurements of fair value are subject to change, and such changes could be significant. We expect to finalize the valuation of these assets and liabilities as soon as practicable, but no later than one year from the respective acquisition dates.
Goodwill and Identified Intangible Assets with Indefinite Lives	Goodwill and Identified Intangible Assets with Indefinite Lives We test goodwill and identified intangible assets with indefinite lives for impairment separately on an annual basis in the fourth quarter of each year. Additionally, we test these assets in the interim if events and circumstances indicate they may be impaired. The events and circumstances that we consider include, but are not limited to, significant under-performance relative to current and historical or projected future operating results and significant changes in our overall business and/or product strategies. If an event or circumstance occurs that would cause us to revise our estimates and assumptions used in analyzing the value of our goodwill and identified intangible assets with indefinite lives, the revision could result in a non-cash impairment charge that could have a material impact on our financial results. We evaluate impairment of goodwill by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the two-step goodwill impairment test. The first step involves a comparison of the fair value of a reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step involves a comparison of the implied fair value and carrying amount of the goodwill of that reporting unit to determine the impairment charge, if any. We quantitatively evaluate identified intangible assets with indefinite lives by estimating the fair value of those assets based on estimated future earnings derived from the assets using the income approach model. Assets with indefinite lives that have been determined to be inseparable due to their interchangeable use are grouped into single units of accounting for purposes of testing for impairment. If the carrying amount of an identified intangible asset with an indefinite life exceeds its fair value, we would recognize an impairment loss equal to the excess of carrying value over fair value.
Identified Intangible Assets with Finite Lives	Identified Intangible Assets with Finite Lives Identified intangible assets with finite lives consist of acquired developed technologies, client relationships, vendor relationships, and trade names. We record intangible assets at fair value and amortize those with finite lives over the shorter of the contractual life or the estimated useful life. We estimate the useful lives of acquired developed product technologies and client relationships based on factors that include the planned use of each developed product technology and the expected pattern of future cash flows to be derived from each developed product technology and existing client relationships. Estimated useful lives for identified intangible assets with finite lives consist of the following: Developed technologies 3 - 5 years Client relationships 3 - 10 years Vendor relationships 7 years Trade names 1 - 7 years We include amortization of acquired developed technologies in "Cost of revenue" and amortization of acquired client relationships, vendor relationships and trade names in "Sales and marketing" expenses in our Consolidated Statements of Operations.
Derivative Financial Instruments	The Company is exposed to interest rate risk related to our variable rate debt. The Company manages this risk through a program that may include the use of interest rate derivatives, the counterparties to which are major financial institutions. Our objective in using interest rate derivatives is to add stability to interest cost by reducing our exposure to interest rate movements. We do not use derivative instruments for trading or speculative purposes. Our interest rate derivatives are designated as cash flow hedges and are carried in the Consolidated Balance Sheets at their fair value. Unrealized gains and losses resulting from changes in the fair value of these instruments are classified as either effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income (“AOCI”), while the ineffective portion is recorded as a component of interest expense in the period of change. Amounts reported in AOCI related to interest rate derivatives are reclassified into interest expense as interest payments are made on our variable-rate debt. If an interest rate derivative agreement is terminated prior to its maturity, the amounts previously recorded in AOCI are recognized into earnings over the period that the forecasted transactions impact earnings. If the hedging relationship is discontinued because it is probable that the forecasted transactions will not occur according to our original strategy, any related amounts previously recorded in AOCI are recognized in earnings immediately.
Deferred Revenue	Professional services and other revenue are recognized as the services are rendered for time and material contracts. Training revenues are recognized after the services are performed. Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from our subscription services described above and is recognized as the revenue recognition criteria are met. For several of our solutions, we invoice our clients in annual, monthly, or quarterly installments in advance of the commencement of the service period. Accordingly, the deferred revenue balance does not represent the total contract value of annual subscription agreements.
Revenue Recognition	Revenue Recognition We derive our revenue from three primary sources: on demand software solutions, on premise software solutions, and professional services. We commence revenue recognition when all of the following conditions are met: • there is persuasive evidence of an arrangement; • the solution and/or service has been provided to the client; • the collection of the fees is probable; and • the amount of fees to be paid by the client is fixed or determinable. If the fees are not fixed or determinable, we recognize revenues as payments become due from clients or when amounts owed are collected, provided all other conditions for revenue recognition have been met. Accordingly, this may materially affect the timing of our revenue recognition and results of operations. When arrangements with clients include multiple software solutions and/or services, we allocate arrangement consideration to each deliverable based on its relative selling price. In such circumstances, we determine the relative selling price for each deliverable based on vendor specific objective evidence of selling price ("VSOE"), if available, or our best estimate of selling price ("BESP"). We have determined that third-party evidence of selling price is not available as our solutions and services are not largely interchangeable with those of other vendors. Our process for determining BESP considers multiple factors, including prices charged by us for similar offerings when sold separately, pricing and discount strategies, and other business objectives. Taxes collected from clients and remitted to governmental authorities are presented on a net basis. On Demand Revenue Our on demand revenue consists of license and subscription fees, transaction fees related to certain of our software-enabled value-added services, and commissions derived from our selling certain risk mitigation services. License and subscription fees are comprised of a charge billed at the initial order date and monthly or annual subscription fees for accessing our on demand software solutions. The license fee billed at the initial order date is recognized as revenue on a straight-line basis over the longer of the contractual term or the period in which the client is expected to benefit, which we consider to be three years. Recognition starts once the product has been activated. Revenue from monthly and annual subscription fees is recognized on a straight-line basis over the access period. We recognize revenue from transaction fees derived from certain of our software-enabled value-added services as the related services are performed. As part of our risk mitigation services to the rental housing industry, we act as an insurance agent and derive commission revenue from the sale of insurance products to individuals. The commissions are based upon a percentage of the premium that the insurance company charges to the policyholder and are subject to forfeiture in instances where a policyholder cancels prior to the end of the policy. Our contract with our underwriting partner provides for contingent commissions to be paid to us in accordance with the agreement. This agreement provides for a calculation that considers, on the policies sold by us, earned premiums less i) earned agent commissions, ii) a percent of premium retained by our underwriting partner, iii) incurred losses, and iv) profit retained by our underwriting partner during the time period. Our estimate of contingent commission revenue considers historical loss experience on the policies sold by us. If the policy is cancelled, our commissions are forfeited as a percent of the unearned premium. As a result, we recognize commissions related to these services as earned ratably over the policy term. On Premise Revenue Sales of our on premise software solutions consist of an annual term license, which includes maintenance and support. Clients can renew their annual term license for additional one -year terms at renewal price levels. We recognize revenue for the annual term license and support services on a straight-line basis over the contract term. We also derive on premise revenue from multiple-element arrangements that include perpetual licenses with maintenance and other services to be provided over a fixed term. Revenue is recognized for delivered items using the residual method when we have VSOE of fair value for the undelivered items and all other criteria for revenue recognition have been met. When VSOE has not been asserted for the undelivered items, we recognize the arrangement fees ratably over the longer of the client support period or the period during which professional services are rendered. Professional and Other Revenue Professional services and other revenue are recognized as the services are rendered for time and material contracts. Training revenues are recognized after the services are performed.
Cost of Revenue	Cost of Revenue Cost of revenue consists primarily of salaries and related personnel expenses of our operations and support personnel, including training and implementation services; expenses related to the operation of our data centers; fees paid to third-party providers; allocations of facilities overhead costs; depreciation; amortization of acquired technologies; and amortization of capitalized software.
Stock-Based Compensation	Stock-Based Expense The Company recognizes compensation expense related to stock options and shares of restricted stock based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The Company generally grants time-based stock options and restricted stock awards, which vest over a specified period of time; market-based awards, which become eligible to vest only after the achievement of a condition based upon the trading price of the Company's common stock and vest over a specified period of time thereafter; and performance-based awards, which become eligible to vest upon the achievement of a specific performance condition, after which they vest over a specified period of time. For time-based stock options and restricted stock awards and performance-based awards, expense is recognized on a straight-line basis over the requisite service period. Expense associated with market-based awards is recognized over the requisite service period using the graded-vesting attribution method.
Advertising Expenses	Advertising Expenses Advertising costs are expensed as incurred and totaled $19.4 million , $16.3 million , and $15.1 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively.
Income Taxes	Income Taxes Income taxes are provided based on the liability method, which results in income tax assets and liabilities arising from temporary differences. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. The liability method requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period in which the rate change was enacted. The liability method also requires that deferred tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized. We establish valuation allowances when necessary to reduce deferred tax assets to the amounts expected to be realized. We evaluate the need for, and the adequacy of, valuation allowances based on the expected realization of our deferred tax assets. The factors used to assess the likelihood of realization include historical earnings, our latest forecast of taxable income, and available tax planning strategies that could be implemented to realize the net deferred tax assets. We may recognize a tax benefit from uncertain tax positions only if it is at least more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon settlement with the taxing authorities. There were no identified tax benefits that were considered uncertain positions at December 31, 2016 and 2015 .
Leases	Leases Some of the operating lease agreements entered into by the Company contain provisions for future rent increases, rent free periods, periods in which rent payments are reduced (abated), or lease incentives. The total amount of rental payments due over the lease term is charged to rent expense on the straight-line method over the term of the lease. The difference between rent expense recorded and the amount paid is credited or charged to “Accrued lease liability,” which is included in “Accrued expenses and other current liabilities" or "Other long-term liabilities" in the accompanying Consolidated Balance Sheets, depending upon when the liability is expected to be relieved.
Fair Value Measurements	Fair Value Measurements Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
Legal Contingencies	Legal Contingencies We review the status of each legal contingency and record a provision for a liability when we consider that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. We review these provisions quarterly and make adjustments where needed as additional information becomes available. If either or both of the criteria are not met, we assess whether there is at least a reasonable possibility that a loss, or additional losses beyond those already accrued, may be incurred. If there is a reasonable possibility that a material loss (or additional material loss in excess of any accrual) may be incurred, we disclose an estimate of the amount of loss or range of losses, either individually or in the aggregate, as appropriate, if such an estimate can be made, or disclose that an estimate of loss cannot be made.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards We adopted Accounting Standards Update (“ASU”) 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs and ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Agreements in the first quarter of 2016. As a result of our retrospective adoption of these standards, we present term loans payable net of unamortized debt issuance costs in the Consolidated Balance Sheets. Prior to adoption of this ASU, such issuance costs were included in other assets. Our adoption of this standard did not result in a reclassification of previously reported amounts, as we did not have outstanding term loans at December 31, 2015. As required, debt issuance costs related to our secured revolving facility continue to be presented in "Other assets" in the Consolidated Balance Sheets. In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments , which eliminates the requirement to restate prior period financial statements for measurement-period adjustments. This ASU requires that the cumulative impact of a measurement period adjustment, including the impact on prior periods, be recognized in the reporting period in which the adjustment is identified. We adopted ASU 2015-16 in the first quarter of 2016. In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This ASU provides guidance to clarify the customer’s accounting for fees paid in a cloud computing arrangement and whether such an arrangement contains a software license or is solely a service contract. We adopted this standard in the first quarter of 2016 and prospectively applied the guidance to all arrangements entered into or materially modified after January 1, 2016. Recently Issued Accounting Standards In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business to assist entities with evaluating whether a set of transferred assets and activities ("set") is a business . Under the new guidance, an entity first determines whether substantially all of the fair value of the set is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. If it is not met, the entity evaluates whether the set meets the requirements that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The ASU requires the changes to be implemented on a prospective basis and is applicable for annual reporting periods beginning after December 15, 2017, including interim periods therein. Early application is permitted. We have not yet selected a transition date and are currently evaluating the potential impact of this amendment on our financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows - Restricted Cash , which requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. This standard is effective for fiscal years beginning after December 15, 2017, including interim periods within, and must be applied retrospectively. Early adoption of this ASU is permitted, including adoption in an interim period, but any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. Management has not yet selected a transition date and is currently evaluating the impact of this ASU on our financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in fiscal years beginning after December 15, 2018. The amendments in this ASU are to be applied through a cumulative-effect adjustment to retained earnings as of the first reporting period in which the ASU is effective. We have not yet selected a transition date and are currently evaluating the impact of adopting ASU 2016-13 on our financial statements. On March 30, 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) . This guidance simplifies accounting for stock-based compensation. A key change is the accounting for excess tax benefits and tax deficiencies. These will be recognized as income tax expense or benefit in the income statement in the period they occur, regardless of whether the benefit reduces taxes payable in the current period. Current GAAP requires tax benefits in excess of compensation cost to be recorded as additional paid-in capital to the extent taxes payable are reduced and tax deficiencies to be recorded in equity to the extent of previous accumulated excess tax benefit and then recorded to the income statement. With the adoption of this ASU, the Company will also record previously unrecognized net operating loss carryforwards of approximately $44.1 million , less any valuation allowance determined to be necessary, related to the excess stock compensation deductions that arose but were not used in prior years. This ASU also will cause excess tax benefits to be reflected as operating cash flows and will allow the Company to elect to either estimate the number of awards that are expected to vest, as in current GAAP, or account for forfeitures as they occur. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016. We will adopt the standard in our interim reporting period beginning January 1, 2017. Each of the various provisions within this standard has its own specified transition method; some will be applied prospectively and others will be applied on a retrospective or modified retrospective basis. On February 25, 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . Current GAAP requires lessees to classify their leases as either capital leases, for which the lessee recognizes a lease liability and a related leased asset, or operating leases, which are not reflected in the lessee’s balance sheet. Under the new guidance, a lessee will be required to recognize assets and liabilities for leases with a term of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease will depend primarily on its classification as a finance or an operating lease. However, unlike current GAAP, which requires only capital leases to be recognized on the balance sheet, ASU 2016-02 will require both operating and finance leases to be recognized on the balance sheet. Additionally, the ASU will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and provides for certain practical expedients. Transition will require application of the new guidance to the beginning of the earliest comparative period presented. We have not yet selected a transition date and are currently evaluating the impact of adopting ASU 2016-02 on our financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . This new standard, as amended by certain supplementary ASU’s released in 2016, will replace most existing GAAP guidance on this topic. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also provides guidance on the recognition of costs to obtain or fulfill a contract with a customer. In August 2015, the FASB approved a one-year deferral of the new revenue reporting standard's effective date for entities reporting under U.S. GAAP. In accordance with the deferral, we have determined that we will adopt the standard in our interim reporting period beginning January 1, 2018. The new guidance may be applied retrospectively to each prior period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method). We currently anticipate adopting the standard using the modified retrospective method. While we are continuing to assess all potential impacts of the standard, we currently expect that adoption of the standard will result in limited changes in the timing of our revenue recognition. We anticipate that commissions paid to our direct sales force will qualify as incremental costs of obtaining a contract and will be capitalized and subsequently amortized. The standard will require additional revenue disclosures in our consolidated financial statements, and we are currently developing our framework for these new disclosures.
