Nature of Business and Operations (Loss)	NOTE 1 - NATURE OF BUSINESS AND OPERATIONS (LOSS) Resource Real Estate Opportunity REIT II, Inc. (the “Company”) was organized in Maryland on September 28, 2012. The Company offered up to 100,000,000 shares of common stock in its primary initial public offering for $10 per share, with discounts available to certain categories of investors. The primary portion of the offering closed on February 6, 2016. The Company continued to offer up to 10,000,000 shares pursuant to the Company’s distribution reinvestment plan at a purchase price equal to 95% of the estimated net asset value per share. On January 23, 2020, the Company filed a Registration Statement to offer an additional 1,500,000 shares pursuant to the Company’s distribution reinvestment plan. The distribution reinvestment plan has been suspended since April 1, 2020 when the board of directors of the Company suspended the declaration of distributions. The Company has adopted a fiscal year ending December 31. Prior to the execution of the REIT I Merger Agreement (as defined below), on September 8, 2020, Resource Real Estate Opportunity REIT, Inc. ("REIT I"), a non-traded real estate investment trust ("REIT") sponsored by Resource Real Estate, LLC (“Resource Real Estate”), our initial sponsor, entered into a series of transactions to become self-managed (the “Self-Management Transaction”) and succeeded to the advisory, asset management and property management arrangements in place for the Company. Accordingly, the sponsor of the Company has changed from Resource Real Estate to Resource Real Estate Opportunity OP, LP, the operating partnership of REIT I, while the REIT I Merger (defined below) is pending. Following the Self-Management Transaction, Resource Real Estate Opportunity Advisor II, LLC (the “Advisor”) is indirectly owned by REIT I. Prior to September 8, 2020, the Advisor was an indirect wholly owned subsidiary of Resource America, Inc. (“RAI”). Pursuant to the advisory agreement initially entered in February 2014 and renewed annually thereafter, the Advisor has acted as the Company's external advisor and manages the Company's day-to-day operations and its portfolio of real estate investments and provides asset-management, marketing, investor relations and other administrative services on the Company's behalf, all subject to the supervision of the Company's board of directors. The advisory agreement was amended and restated on September 8, 2020. RAI is a wholly owned subsidiary of C-III Capital Partners, LLC (“C-III”). Prior to the Self-Management Transaction, C-III controlled the Advisor, Resource Real Estate Opportunity Manager II, LLC, the Company's property manager (the “Manager”) and Resource Securities LLC, the dealer manager for the Company’s public offering, as well as all of the shares of common stock held by the Advisor and RAI. Prior to the Self-Management Transaction, the Advisor transferred all of its shares of the Company’s common stock to a subsidiary of C-III. As of September 30, 2020, a total of 60,206,977 shares, including the additional shares purchased by the Advisor and shares issued through the distribution reinvestment plan, have been issued resulting in gross offering proceeds of $644.8 million. As of September 30, 2020, the Company had issued 10,197,719 shares for $88.5 million pursuant to its distribution reinvestment plan. The Company’s objective is to take advantage of the multifamily investing and lending platforms available to the Advisor to invest in apartment communities in order to provide the investor with growing cash flow and increasing asset values. The Company has acquired and may continue to acquire underperforming apartments which it will renovate and stabilize in order to increase rents. To a lesser extent, the Company may acquire or originate commercial real estate debt secured by apartments. The Company elected to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986, as amended, commencing with its taxable year ending December 31, 2014. As such, to maintain its REIT qualification for U.S. federal income tax purposes, the Company is generally required to distribute at least 90% of its net income (excluding net capital gains) to its stockholders as well as comply with certain other requirements. Accordingly, the Company generally will not be subject to U.S. federal income taxes to the extent that it annually distributes all of its REIT taxable income to its stockholders. The Company also operates its business in a manner that will permit it to maintain its exemption from registration under the Investment Company Act of 1940, as amended. The consolidated financial statements and the information and tables contained in the notes thereto, as of September 30, 2020, are unaudited and prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). However, in the opinion of management, these interim financial statements include all of the necessary adjustments to fairly present the results of the interim periods presented. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for the nine months ended September 30, 2020 may not necessarily be indicative of the results of operations for the full year ending December 31, 2020. Pending Mergers with Resource Real Estate Opportunity REIT, Inc. and Resource Apartment REIT III, Inc. On September 8, 2020, the Company entered into merger agreements (as described herein) to acquire each of REIT I and Resource Apartment REIT III, Inc. (“REIT III”). Both mergers are stock-for-stock transactions whereby each of REIT I and REIT III will be merged into a wholly owned subsidiary of the Company. The consummation of the Company’s merger with REIT I is not contingent upon the completion of the merger with REIT III, and the consummation of the Company’s merger with REIT III is not contingent upon completion of the merger with REIT I. We refer to the REIT I Merger (as defined below) and the REIT III Merger (as defined below) collectively as the Mergers. REIT I Merger On September 8, 2020, the Company, RRE Opportunity OP II, LP (“OP II”), Revolution I Merger Sub, LLC, a wholly owned subsidiary of the Company (“Merger Sub I”), REIT I, and Resource Real Estate Opportunity OP, LP (“OP I”), entered into an Agreement and Plan of Merger (the “REIT I Merger Agreement”). Subject to the terms and conditions of the REIT I Merger Agreement, (i) REIT I will merge with and into Merger Sub I, with Merger Sub I surviving as a direct, wholly owned subsidiary of the Company (the “REIT I Company Merger”) and (ii) OP I will merge with and into OP II (the “REIT I Partnership Merger” and, together with the REIT I Company Merger, the “REIT I Merger”), with OP II surviving the REIT I Partnership Merger. At such time, the separate existence of REIT I and OP I shall cease. At the effective time of the REIT I Company Merger, each issued and outstanding share of REIT I’s common stock (or fraction thereof) will be converted into the right to receive 1.22423 shares of common stock of the Company, and each issued and outstanding share of REIT I’s convertible stock will be converted into the right to receive $0.02 in cash (without interest). At the effective time of the REIT I Partnership Merger, each common unit of partnership interests in OP I outstanding immediately prior to the effective time of the REIT I Partnership Merger will convert into the right to receive 1.22423 common units of partnership interest in OP II and each Series A Cumulative Participating Redeemable Preferred Unit in OP I issued and outstanding immediately prior to the effective time of the REIT I Partnership Merger will convert into the right to receive one Series A Cumulative Participating Redeemable Preferred Unit in OP II. The obligations of each party to consummate the REIT I Merger are subject to a number of conditions, including receipt of the approval of the REIT I Merger and of an amendment to the REIT I charter to delete certain provisions regarding roll-up transactions by the holders of a majority of the outstanding shares of the REIT I common stock. REIT III Merger On September 8, 2020, the Company, OP II, Revolution III Merger Sub, LLC (“Merger Sub III”), a wholly owned subsidiary of the Company, REIT III, and Resource Apartment OP III, LP (“OP III”), the operating partnership of REIT III, entered into an Agreement and Plan of Merger (the “REIT III Merger Agreement”). Subject to the terms and conditions of the REIT III Merger Agreement, (i) REIT III will merge with and into Merger Sub III, with Merger Sub III surviving as a direct, wholly owned subsidiary of the Company (the “REIT III Company Merger”) and (ii) OP III will merge with and into OP II (the “REIT III Partnership Merger” and, together with the REIT III Company Merger, the “REIT III Merger”), with OP II surviving the REIT III Partnership Merger. At such time, the separate existence of REIT III and OP III shall cease. At the effective time of the REIT III Company Merger, each issued and outstanding share of REIT III’s common stock (or fraction thereof) will be converted into the right to receive 0.925862 shares of common stock of the Company. At the effective time of the REIT III Partnership Merger, each unit of partnership interests in OP III outstanding immediately prior to the effective time of the REIT III Partnership Merger will be retired and will cease to exist. In addition, for each share of common stock of the Company issued in the REIT III Company Merger, a common partnership unit will be issued by OP II to the Company. The obligations of each party to consummate the REIT III Merger are subject to a number of conditions, including receipt of the approval of the REIT III Merger and of an amendment to the REIT III charter to delete certain provisions regarding roll-up transactions by the holders of a majority of the outstanding shares of the REIT III common stock. COVID-19 Pandemic One of the most significant risks and uncertainties facing the Company and the real estate industry generally continues to be the effect of the ongoing public health crisis of the novel coronavirus disease (COVID-19) pandemic. The Company continues to closely monitor the impact of the COVID-19 pandemic on all aspects of its business, including how the pandemic is impacting its tenants. The Company did not incur significant disruptions from the COVID-19 pandemic during the nine months ended September 30, 2020; however, a small percentage of its tenants have requested rent deferral as a result of the pandemic. The Company is evaluating each tenant rent relief request on an individual basis, considering a number of factors. Not all tenant requests will ultimately result in modified agreements, nor is the Company forgoing its contractual rights under its lease agreements. Executed short-term rent relief plans that are outstanding at September 30, 2020 are not significant in terms of either number of requests or dollar value. The extent to which the COVID-19 pandemic impacts the Company’s operations and those of its tenants depends on future developments, which cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures. The Company is unable to predict the ultimate impact that the pandemic will have on its financial condition, results of operations and cash flows due to numerous uncertainties.
