Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recent Developments	Recent Developments In April 2021, the Company received notification from the Small Business Administration ("SBA") that the Company's Paycheck Protection Program ("PPP") Loan had been forgiven and the SBA lender had received payment in full (See Note 8 – Coronavirus Aid and Relief and Economic Security Act). On June 16, 2021, the Company made the strategic decision to sell the operations of Comstock Environmental Services, LLC ("CES"), a subsidiary of Comstock, based on the continued growth of the asset management business as well as its future prospects. For all periods presented, the related operating results are presented as income (loss) from discontinued operations on the Condensed Consolidated Statement of Operations. The assets and liabilities of CES are also designated as held for sale on the Condensed Consolidated Balance Sheets (See Note 3 - Discontinued Operations).
Use of Estimates	Use of Estimates Our condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts for the reporting periods. We base these estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances. We evaluate these estimates and judgments on an ongoing basis. Actual results may differ from those estimates under different assumptions or conditions. Material estimates are utilized in the valuation of deferred tax assets, analysis of goodwill impairment, valuation of equity-based compensation, and fair value of financial instruments (including the fair value of our equity method investments).
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740, Income Tax and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for public business entities for annual reporting periods beginning after December 15, 2020, and interim periods within those periods. The Company adopted ASU 2019-12 as of January 1, 2021. The adoption did not have a material impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments", which modifies how companies recognize expected credit losses on financial instruments and other commitments to extend credit held by an entity at each reporting date. Existing GAAP requires an “incurred loss” methodology whereby companies are prohibited from recording an expected loss until it is probable that the loss has been incurred. ASU 2016-13 requires companies to use a methodology that reflects current expected credit losses (“CECL”) and requires consideration of a broad range of reasonable and supportable information to record and report credit loss estimates, even when the CECL is remote. Companies will be required to record the allowance for credit losses and deduct that amount from the basis of the asset. The guidance is effective for the Company for financial statement periods beginning after December 15, 2022, although early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and related disclosures. We assessed other accounting pronouncements issued or effective during the three and six months ended June 30, 2021 and deemed they were either not applicable to us or are not anticipated to have a material effect on our consolidated financial statements. Other standards previously issued and adopted by the Company have been disclosed in previous filings.
