Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Liability to Landlord Insurance We have a wholly owned subsidiary, Terra Mar Insurance Company, Inc., which was established to provide our customers with the option to purchase legal liability to landlord insurance. If our customers choose to use our insurance services, they are issued an insurance policy underwritten by our third-party service provider. The policy has a limit of $100,000 per incident for each insured residence. We have entered into a reinsurance agreement with our third-party service provider and, as a result, we assume a 100% quota share of the legal liability to landlord insurance provided to our customers through our third-party service provider. Included in cost of revenue we accrue for reported claims, and an estimate of losses incurred but not reported by our property management customers, as we bear the risk related to claims. Our liability for reported claims and incurred but not reported claims at December 31, 2020 and 2019 was $1.5 million and $1.8 million, respectively, and is included in other current liabilities on our Consolidated Balance Sheets. Included in prepaid expenses and other current assets as of December 31, 2020 and 2019 are $2.7 million and $1.3 million, respectively, of deposits held with a third party related to requirements to maintain collateral for our insurance services. Legal Proceedings In July 2019, we received a Request for Information from the Civil Rights Division (Housing and Civil Enforcement Section) of the U.S. Department of Justice ("DOJ") requesting certain information relating to our compliance with the Servicemembers Civil Relief Act in connection with our tenant screening Value+ service. On November 6, 2020, the DOJ issued a no action letter, declining to take any action against us and closing its investigation. In December 2018, we received a Civil Investigative Demand from the Federal Trade Commission ("FTC") requesting certain information relating to our compliance with the Fair Credit Reporting Act in connection with our tenant screening Value+ service (the "FTC Investigation"). On April 30, 2020, the FTC staff informed us of its belief that there is a reasonable basis for asserting claims against us for our alleged failure to comply with certain sections of the FCRA that could result in monetary penalty and/or injunctive relief. We disagree with the stated belief of the FTC and vigorously defended our position. Notwithstanding our disagreement with the FTC's position, and primarily in an effort to avoid protracted litigation and potential distraction to our business, we entered into settlement negotiations with the FTC in an effort to resolve all claims and allegations arising out of or relating to the FTC Investigation. Those settlement negotiations resulted in a final agreement between the parties that is memorialized in a Stipulated Order for Permanent Injunction and Civil Penalty Judgment filed in the United States District Court for the District of Columbia on January 12, 2021. We admitted no wrongdoing in connection with the settlement. In the second quarter of 2020, we determined that a loss stemming from the FTC Investigation was probable and that a reasonable estimate of the loss was approximately $4.3 million. Accordingly, an accrual of $4.3 million is included within accrued expenses on our Consolidated Balance Sheet as of December 31, 2020. The ultimate settlement amount of $4.3 million was paid in January 2021. In addition to the foregoing, from time to time, we are involved in various other investigatory inquiries or legal proceedings arising from or related to matters incident to the ordinary course of our business activities, including actions with respect to intellectual property, employment, regulatory and contractual issues. Although the results of such investigatory inquiries and legal proceedings cannot be predicted with certainty, we believe that we are not currently a party to any investigatory inquiries or legal proceeding(s) which, if determined adversely to us, would, individually or taken together, have a material adverse effect on our business, operating results, financial condition or cash flows. Indemnification In the ordinary course of business, we may provide indemnification of varying scope and terms to customers, investors, directors and officers with respect to certain matters, including, but not limited to, losses arising out of our breach of any applicable agreements, services to be provided by us, or intellectual property infringement claims made by third parties. These indemnification provisions may survive termination of the underlying agreement and the maximum potential amount of future payments we could be required to make under these indemnification provisions may not be subject to maximum loss clauses and is indeterminable. We have never paid a material claim, nor have any legal claims been brought against us, in connection with these indemnification arrangements. At December 31, 2020 and 2019, we have not accrued a liability for these indemnification arrangements because we determined that the likelihood of incurring a payment obligation, if any, in connection with these indemnification arrangements is not probable or reasonably possible and the amount or range of amounts of any such liability is not reasonably estimable.
