Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and Description of Business NexPoint Residential Trust, Inc. (the “Company”, “we”, “our”) was incorporated in Maryland on September 19, 2014, and has elected to be taxed as a real estate investment trust (“REIT”). The Company is focused on “value-add” multifamily investments primarily located in the Southeastern and Southwestern United States. Substantially all of the Company’s business is conducted through NexPoint Residential Trust Operating Partnership, L.P. (the “OP”), the Company’s operating partnership. The Company owns its properties (the “Portfolio”) through the OP and its wholly owned taxable REIT subsidiary (“TRS”). The OP owns approximately 99.9% of the Portfolio; the TRS owns approximately 0.1% of the Portfolio. The Company’s wholly owned subsidiary, NexPoint Residential Trust Operating Partnership GP, LLC (the “OP GP”), is the sole general partner of the OP. As of December 31, 2017, there were 21,116,902 common units in the OP (“OP Units”) outstanding, of which 21,043,669, or 99.7%, were owned by the Company and 73,233, or 0.3%, were owned by a noncontrolling limited partner (see Note 10). The Company began operations on March 31, 2015 as a result of the transfer and contribution by NexPoint Credit Strategies Fund (“NHF”) of all but one of the multifamily properties owned by NHF through its wholly owned subsidiary NexPoint Real Estate Opportunities, LLC (fka Freedom REIT, LLC) (“NREO”). We use the term “predecessor” to mean the carve-out business of NREO. On March 31, 2015, NHF distributed all of the outstanding shares of the Company's common stock held by NHF to holders of NHF common shares. We refer to the distribution of our common stock by NHF as the “Spin-Off.” The Company is externally managed by NexPoint Real Estate Advisors, L.P. (the “Adviser”), through an agreement dated March 16, 2015, as amended, and renewed on February 12, 2018 for a one-year term set to expire on March 16, 2019 (the “Advisory Agreement”), by and among the Company, the OP and the Adviser. The Adviser conducts substantially all of the Company’s operations and provides asset management services for its real estate investments. The Company expects it will only have accounting employees while the Advisory Agreement is in effect. All of the Company’s investment decisions are made by the Adviser, subject to general oversight by the Adviser’s investment committee and the Company’s board of directors (the “Board”). The Adviser is wholly owned by NexPoint Advisors, L.P., which is an affiliate of Highland Capital Management, L.P. (the “Sponsor” or “Highland”). The Company’s investment objectives are to maximize the cash flow and value of properties owned, acquire properties with cash flow growth potential, provide quarterly cash distributions and achieve long-term capital appreciation for its stockholders through targeted management and a value-add program. Consistent with the Company’s policy to acquire assets for both income and capital gain, the Company intends to hold at least majority interests in its properties for long-term appreciation and to engage in the business of directly or indirectly acquiring, owning, and operating well-located multifamily properties with a value-add component in large cities and suburban submarkets of large cities primarily in the Southeastern and Southwestern United States consistent with its investment objectives. Economic and market conditions may influence the Company to hold properties for different periods of time. From time to time, the Company may sell a property if, among other deciding factors, the sale would be in the best interest of its stockholders. The Company may also participate with third parties in property ownership through limited liability companies (“LLCs”), funds or other types of co-ownership or acquire real estate or interests in real estate in exchange for the issuance of common stock, OP Units, preferred stock or options to purchase stock. These types of investments may permit the Company to own interests in larger assets without unduly restricting diversification, which provides flexibility in structuring the Company’s portfolio. The Company may allocate up to thirty percent of the portfolio to investments in real estate-related debt and securities with the potential for high current income or total returns. These allocations may include first and second mortgages and subordinated, bridge, mezzanine, construction and other loans, as well as debt securities related to or secured by multifamily real estate and common and preferred equity securities, which may include securities of other REITs or real estate companies.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Predecessor With the exception of a nominal amount of initial cash funded at inception, the Company did not own any assets prior to March 31, 2015. The business and operations of the Company prior to March 31, 2015 occurred under the predecessor. The predecessor included all of the properties in the Portfolio that were held directly or indirectly by NREO prior to the Spin-Off that occurred on March 31, 2015. However, the Company’s combined consolidated financial statements reflect operations of the predecessor through March 31, 2015 as if they were incurred by the Company. The predecessor was determined in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). References throughout these combined consolidated financial statements to the “Company”, “we”, or “our”, include the activity of the predecessor defined above. Basis of Accounting The accompanying combined consolidated financial statements have been prepared according to the rules and regulations of the SEC. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted according to such rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments and eliminations necessary for the fair presentation of the Company’s financial position as of December 31, 2017, and results of operations for the years ended December 31, 2017, 2016 and 2015 have been included. Such adjustments are normal and recurring in nature. The accompanying combined consolidated financial statements are presented in accordance with GAAP. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the dates of the combined consolidated financial statements and the amounts of revenues and expenses during the reporting periods. Actual amounts realized or paid could differ from those estimates. All significant intercompany accounts and transactions have been eliminated in consolidation. There have been no significant changes to the Company’s significant accounting policies during the year ended December 31, 2017. Principles of Consolidation The Company accounts for subsidiary partnerships, joint ventures and other similar entities in which it holds an ownership interest in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation Revenue Recognition The Company’s primary operations consist of rental income earned from its residents under lease agreements typically with terms of one year or less. Rental income is recognized when earned. This policy effectively results in income recognition on the straight-line method over the related terms of the leases. Resident reimbursements and other income consist of charges billed to residents for utilities, carport and garage rental, and pets, administrative, application and other fees and are recognized when earned. Real Estate Investments Upon acquisition of a property, the purchase price and related acquisition costs (“total consideration”) are allocated to land, buildings, improvements, furniture, fixtures, and equipment, and intangible lease assets in accordance with FASB ASC 805, Business Combinations Clarifying the Definition of a Business (Topic 805) The allocation of total consideration, which is determined using inputs that are classified within Level 3 of the fair value hierarchy established by FASB ASC 820, Fair Value Measurement and Disclosures Real estate assets, including land, buildings, improvements, furniture, fixtures and equipment, and intangible lease assets are stated at historical cost less accumulated depreciation and amortization. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. Expenditures for improvements, renovations, and replacements are capitalized at cost. Real estate-related depreciation and amortization are computed on a straight-line basis over the estimated useful lives as described in the following table: Land Not depreciated Buildings 30 years Improvements 15 years Furniture, fixtures, and equipment 3 years Intangible lease assets 6 months Construction in progress includes the cost of renovation projects being performed at the various properties. Once a project is complete, the historical cost of the renovation is placed into service in one of the categories above depending on the type of renovation project and is depreciated over the estimated useful lives as described in the table above. Real estate assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In such cases, the Company will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value. The Company periodically classifies real estate assets as held for sale when certain criteria are met, in accordance with GAAP. At that time, the Company presents the net real estate assets and the net debt associated with the real estate held for sale separately in its consolidated balance sheet, and the Company ceases recording depreciation and amortization expense related to that property. Real estate held for sale is reported at the lower of its carrying amount or its estimated fair value less estimated costs to sell. Reclassifications Certain reclassifications have been made to amounts in the prior year combined consolidated statements of operations and comprehensive income (loss) to conform to current year presentations as a result of an accounting policy election to classify certain expenses incurred in connection with the extinguishment or modification of debt separately from interest expense. These expenses are recorded in loss on extinguishment of debt and modification costs on the combined consolidated statements of operations and comprehensive income (loss). As a result, for the years ended December 31, 2016 and 2015, interest expense decreased (and loss on extinguishment of debt and modification costs increased) by approximately $1.7 million and $0.7 million, respectively. See Note 6 for additional information. Reportable Segment Substantially all of the Company’s net income (loss) is from investments in real estate properties within the multifamily sector that the Company owns through LLCs. The Company evaluates operating performance on an individual property level and views its real estate assets as one industry segment and, accordingly, its properties are aggregated into one reportable segment. Income Taxes The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and expects to continue to qualify as a REIT. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement to distribute annually at least 90% of its “REIT taxable income,” as defined by the Code, to its stockholders. As a REIT, the Company will be subject to federal income tax on its undistributed REIT taxable income and net capital gain and to a 4% nondeductible excise tax on any amount by which distributions it pays with respect to any calendar year are less than the sum of (1) 85% of its ordinary income, (2) 95% of its capital gain net income and (3) 100% of its undistributed income from prior years. The Company intends to operate in such a manner so as to qualify as a REIT, but no assurance can be given that the Company will operate in a manner so as to qualify as a REIT. Taxable income from certain non-REIT activities is managed through a TRS and is subject to applicable federal, state, and local income and margin taxes. The Company had no significant taxes associated with its TRS for the years ended December 31, 2017, 2016 and 2015. If the Company fails to meet these requirements, it could be subject to federal income tax on all of the Company’s taxable income at regular corporate rates for that year. The Company would not be able to deduct distributions paid to stockholders in any year in which it fails to qualify as a REIT. Additionally, the Company will also be disqualified from electing to be taxed as a REIT for the four taxable years following the year during which qualification was lost unless the Company is entitled to relief under specific statutory provisions. As of December 31, 2017, the Company believes it is in compliance with all applicable REIT requirements. The Company evaluates the accounting and disclosure of tax positions taken or expected to be taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” (greater than 50 percent probability) of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. The Company’s management is required to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions, which include federal and certain states. The Company has no examinations in progress and none are expected at this time. The Company recognizes its tax positions and evaluates them using a two-step process. First, the Company determines whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Second, the Company will determine the amount of benefit to recognize and record the amount that is more likely than not to be realized upon ultimate settlement. The Company had no material unrecognized tax benefit or expense, accrued interest or penalties as of December 31, 2017. The Company and its subsidiaries are subject to federal income tax as well as income tax of various state and local jurisdictions. The 2016 and 2015 tax years remain open to examination by tax jurisdictions to which the Company and its subsidiaries are subject. When applicable, the Company recognizes interest and/or penalties related to uncertain tax positions on its combined consolidated statements of operations and comprehensive income (loss). Recent Accounting Pronouncements Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 13(a) of the Securities Exchange Act of 1934, as amended, for complying with new or revised accounting standards applicable to public companies. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company has elected to take advantage of this extended transition period. As a result of this election, the Company’s financial statements may not be comparable to companies that comply with public company effective dates for such new or revised standards. The Company may elect to comply with public company effective dates at any time, and such election would be irrevocable pursuant to Section 107(b) of the JOBS Act. The following recent accounting pronouncements reflect effective dates that delay the adoption until those standards would otherwise apply to private companies.

Investments in Subsidiaries	3. Investments in Subsidiaries The Company has in the past and may in the future invest in joint ventures. The Company consolidates the entities that it controls as well as any VIEs where it is the primary beneficiary. In connection with its indirect equity investments in the properties acquired, the Company, through the OP and the TRS, directly or indirectly holds 100% of the membership interests in single-asset LLCs that directly own the properties. All of the properties the Company has acquired are consolidated in the Company’s financial statements. The assets of each entity can only be used to settle obligations of that particular entity, and the creditors of each entity have no recourse to the assets of other entities or the Company. Additionally, the Company has in the past and may in the future enter into purchase and sale transactions structured as reverse like-kind exchanges (“1031 Exchanges”) under Section 1031 of the Code. For a reverse 1031 Exchange in which the Company purchases a new property prior to selling the property to be matched in the like-kind exchange (the Company refers to a new property being acquired in the 1031 Exchange prior to the sale of the related property as a “Parked Asset”), legal title to the Parked Asset is held by an Exchange Accommodation Titleholder (“EAT”) engaged to execute the 1031 Exchange until the sale transaction and the 1031 Exchange are completed. The Company, through a wholly owned subsidiary, enters into a master lease agreement with the EAT whereby the EAT leases the acquired property and all other rights acquired in connection with the acquisition to the Company. The term of the master lease agreement is until the earlier of the completion of the reverse 1031 Exchange or 180 days from the date that the property was acquired. The EAT is classified as a VIE as it does not have sufficient equity investment at risk to finance its activities without additional subordinated financial support. The Company consolidates the EAT as its primary beneficiary because it has the ability to control the activities that most significantly impact the EAT's economic performance and the Company retains all of the legal and economic benefits and obligations related to the Parked Assets prior to completion of the 1031 Exchange. As such, the Parked Assets are included in the Company’s combined consolidated financial statements as VIEs until legal title is transferred to the Company upon either completion of the 1031 Exchange or termination of the master lease agreements, at which time they will be consolidated as wholly owned subsidiaries. As of December 31, 2017, the Company, through the OP and the wholly owned TRS, owned 33 properties. The following table represents the Company’s ownership in each property as of December 31, 2017 and 2016: Effective Ownership Percentage at December 31, Property Name Location Year 2017 2016 The Miramar Apartments Dallas, Texas 2013 — (1) 100 % Arbors on Forest Ridge Bedford, Texas 2014 100 % (2) 90 % Cutter's Point Richardson, Texas 2014 100 % (2) 90 % Eagle Crest Irving, Texas 2014 100 % (2) 90 % Silverbrook Grand Prairie, Texas 2014 100 % (2) 90 % Timberglen (3) Dallas, Texas 2014 100 % (2) 90 % Toscana Dallas, Texas 2014 — (1) 90 % The Grove at Alban Frederick, Maryland 2014 — (1) 76 % (4) Edgewater at Sandy Springs Atlanta, Georgia 2014 100 % (2) 90 % Beechwood Terrace Antioch, Tennessee 2014 100 % (2) 90 % Willow Grove Nashville, Tennessee 2014 100 % (2) 90 % Woodbridge Nashville, Tennessee 2014 100 % (2) 90 % Abbington Heights Antioch, Tennessee 2014 100 % (2) 90 % (4) The Summit at Sabal Park Tampa, Florida 2014 100 % (2) 90 % (4) Courtney Cove Tampa, Florida 2014 100 % (2) 90 % (4) Radbourne Lake Charlotte, North Carolina 2014 100 % (2) 90 % (4) Timber Creek Charlotte, North Carolina 2014 100 % (2) 90 % (4) Belmont at Duck Creek Garland, Texas 2014 100 % (2) 90 % (4) The Arbors Tucker, Georgia 2014 — (1) 90 % (4) The Crossings Marietta, Georgia 2014 — (1) 90 % (4) The Crossings at Holcomb Bridge Roswell, Georgia 2014 — (1) 90 % (4) The Knolls Marietta, Georgia 2014 — (1) 90 % (4) Regatta Bay Seabrook, Texas 2014 — (1) 90 % (4) Sabal Palm at Lake Buena Vista Orlando, Florida 2014 100 % (2) 90 % (4) Southpoint Reserve at Stoney Creek (3) Fredericksburg, Virginia 2014 100 % (2) 85 % (4) Cornerstone Orlando, Florida 2015 100 % (2) 90 % (4) Twelve 6 Ten at the Park Dallas, Texas 2015 — (1) 90 % (4) The Preserve at Terrell Mill Marietta, Georgia 2015 100 % (2) 90 % (4) The Ashlar Dallas, Texas 2015 100 % (2) 90 % (4) Heatherstone Dallas, Texas 2015 100 % (2) 90 % (4) Versailles Dallas, Texas 2015 100 % (2) 90 % (4) Seasons 704 Apartments West Palm Beach, Florida 2015 100 % (2) 90 % (4) Madera Point Mesa, Arizona 2015 100 % (2) 95 % The Pointe at the Foothills Mesa, Arizona 2015 100 % (2) 95 % Venue at 8651 Fort Worth, Texas 2015 100 % (2) 95 % Parc500 West Palm Beach, Florida 2016 100 % (2) 91 % The Colonnade Phoenix, Arizona 2016 100 % (2) 97 % Old Farm Houston, Texas 2016 100 % (2) 100 % (5) Stone Creek at Old Farm Houston, Texas 2016 100 % (2) 100 % (5) Hollister Place Houston, Texas 2017 100 % — (6) Rockledge Apartments Marietta, Georgia 2017 100 % — (6) Atera Apartments (7) Dallas, Texas 2017 100 % — (6) (1) Properties were sold during the year ended December 31, 2017.

Upon the transfer of title, the property owners were no longer considered Parked Assets or VIEs (see Note 5). (6) Properties were acquired in 2017; therefore, no ownership as of December 31, 2016. (7) Entity that directly owned the property was consolidated as a VIE at December 31, 2017.

Due to the six-month useful life attributable to intangible lease assets, the value of intangible lease assets on any acquisition prior to June 30, 2017 has been fully amortized and the assets and related accumulated amortization have been written off as of December 31, 2017. Acquisitions The following table presents the Company’s acquisitions of real estate during the year ended December 31, 2017 (dollars in thousands); the Company acquired four properties for a combined purchase price of approximately $175.1 million during the year ended December 31, 2016.

(7) Debt in the amount of $18.0 million was assumed upon acquisition of this property at approximated fair value. The assumed debt carries a 4.09% fixed rate, was originally issued in March 2013, and had a term of 120 months with an initial 24 months of interest only. At the time of acquisition, the principal balance of the first mortgage remained unchanged and had a remaining term of 98 months with 2 months of interest only. The first mortgage is pre-payable and subject to yield maintenance from the 13 th (8) Debt was assumed upon acquisition of this property at approximated fair value. The loan is open to pre-payment in the last four months of the term. (9) Loan can be pre-paid in the first 12 months of the term at par plus 5.00%. Starting in the 13th month of the term through the 81st month of the term, the loan can be pre-paid at par plus 1.00% of the unpaid principal balance and at par during the last three months of the term. The property was held in a consolidated VIE at December 31, 2017. The Company completed the reverse portion of the 1031 Exchange of the property with the sale of Timberglen on January 31, 2018, at which time legal title to the property transferred to the Company. Upon the transfer of title, the property owner is no longer considered a VIE (see Note 13). (10) The Company reflected valuation adjustments on its fixed rate debt for Belmont at Duck Creek and Parc500 to adjust it to fair market value on the date of acquisition for the difference between the fair value and the assumed principal amount of debt. The difference is amortized into interest expense over the remaining terms of the mortgages. On June 30, 2017, the Company entered into 22 first mortgages, with a combined principal amount of $502.1 million, on certain of its properties, replacing the $168.4 million of existing mortgage debt outstanding on nine properties and the $300.0 million outstanding under a credit facility (the “$300 Million Credit Facility”). The refinancing of the existing mortgage debt incurred approximately $1.7 million of prepayment penalties, which is included in loss on extinguishment of debt and modification costs on the combined consolidated statements of operations and comprehensive income (loss). The Federal Home Loan Mortgage Corporation (“Freddie Mac”), who was the lender on the existing mortgage debt and the $300 Million Credit Facility, also originated the 22 new first mortgages (the “Freddie Refinance”). In accordance with FASB ASC 470-50, Debt – Modifications and Extinguishments The following nine properties had existing mortgage debt that was refinanced: The Summit at Sabal Park, Courtney Cove, The Preserve at Terrell Mill, The Ashlar, Heatherstone, Versailles, Seasons 704 Apartments, Madera Point and The Pointe at the Foothills. The following twelve properties, which were refinanced as described above, were previously cross-collateralized as security for the $300 Million Credit Facility: Arbors on Forest Ridge, Cutter’s Point, Eagle Crest, Silverbrook, Timberglen, Edgewater at Sandy Springs, Beechwood Terrace, Willow Grove, Woodbridge, Venue at 8651, Old Farm and Stone Creek at Old Farm. The Colonnade, which obtained a first mortgage as described above, was not previously encumbered by mortgage debt or credit facility debt. During the year ended December 31, 2017, the Company sold nine properties and repaid the related mortgage loans that encumbered eight of the properties, as detailed in the table below (in thousands): Property Name Date of Sale Type Outstanding Principal (1) The Miramar Apartments April 3, 2017 Floating $ 8,400 The Grove at Alban April 3, 2017 Floating 18,374 Twelve 6 Ten at the Park April 27, 2017 Floating 15,711 Regatta Bay July 14, 2017 Floating 14,000 The Arbors, The Crossings, The Crossings at Holcomb Bridge and The Knolls (2) September 29, 2017 Floating 50,177 $ 106,662 (1) Represents the outstanding principal balance when the loan was repaid. (2) Properties were sold as a portfolio. The ninth property the Company sold, Toscana, was released from the collateral pool of the $300 Million Credit Facility upon its sale on April 3, 2017. The Company incurred prepayment penalties of approximately $0.9 million in connection with the payoff of these mortgage loans and $0.1 million of fees in connection with the release of Toscana, both of which are included in loss on extinguishment of debt and modification costs on the combined consolidated statements of operations and comprehensive income (loss). The weighted average interest rate of the Company’s mortgage indebtedness was 3.34% as of December 31, 2017 and 2.95% as of December 31, 2016. The increase between the periods is primarily related to increases in LIBOR, partially offset by a weighted average reduction of 57 basis points in the borrowing spread related to the Freddie Refinance. As of December 31, 2017, the adjusted weighted average interest rate of the Company’s mortgage indebtedness was 3.14%. For purposes of calculating the adjusted weighted average interest rate of the outstanding mortgage indebtedness, the Company has included the weighted average fixed rate of 1.3388% on its combined $650.0 million notional amount of interest rate swap agreements, which effectively fix the interest rate on $650.0 million of the Company’s floating rate mortgage indebtedness (see Note 7). The interest rate cap agreements the Company has entered into effectively cap one-month LIBOR on $273.5 million of the Company’s floating rate mortgage indebtedness at a weighted average rate of 4.26% (see Note 7). Each of the Company’s mortgages is a non-recourse obligation subject to customary provisions. The loan agreements contain customary events of default, including defaults in the payment of principal or interest, defaults in compliance with the covenants contained in the documents evidencing the loan, defaults in payments under any other security instrument covering any part of the property, whether junior or senior to the loan, and bankruptcy or other insolvency events. As of December 31, 2017, the Company believes it is in compliance with all provisions. Freddie Mac Multifamily Green Advantage . In order to obtain more favorable pricing on the Company’s mortgage debt financing with Freddie Mac, the Company has decided to participate in Freddie Mac’s new Multifamily Green Advantage program. The Company has escrowed approximately $4.2 million to finance smarter, greener property improvements at 20 of its properties, which will be completed by the end of 2018. The Company plans to reduce water/sewer costs at each property by at least 15% through the replacement of showerheads, plumbing fixtures and toilets with modern energy efficient upgrades. By participating in this program, the Company was able to lower the interest rate on the properties it refinanced in the Freddie Refinance by 10 basis points. Credit and Bridge Facilities The following table contains summary information concerning the Company’s credit and bridge facilities as of December 31, 2017 (dollars in thousands): Type Term Outstanding Principal Interest Rate (1) Maturity Date $30 Million Credit Facility Floating 24 $ 30,000 5.56% 12/29/2018 Deferred financing costs, net of accumulated amortization of $155 (157 ) $ 29,843 2017 Bridge Facility Floating 4 $ 8,597 5.31% 3/31/2018 Deferred financing costs, net of accumulated amortization of $277 (21 ) $ 8,576 (1) Interest rate is based on one-month LIBOR plus an applicable margin. One-month LIBOR as of December 31, 2017 was 1.5643%. $30 Million Credit Facility . On December 29, 2016, the Company, through the OP, entered into a $30.0 million credit facility (the “$30 Million Credit Facility”) with KeyBank National Association (“KeyBank”) and immediately drew $15.0 million to fund a portion of the purchase price of Old Farm and Stone Creek at Old Farm. On February 1, 2017, the Company drew $14.0 million and used $12.0 million to fund a portion of the purchase price of Hollister Place and $2.0 million to fund value-add renovations at the Company’s properties. In April 2017, the Company used cash on hand plus its share of the proceeds, net of distributions to noncontrolling interests, from four properties it sold to pay down $10.0 million on the $30 Million Credit Facility. On June 30, 2017, the Company drew $11.0 million to fund a portion of the BH Buyout. The $30 Million Credit Facility is a full-term, interest-only facility, has one 12-month extension option and is guaranteed by the OP. 2017 Bridge Facility . On June 30, 2017 , the Company, through the OP, entered into a $65.9 million bridge facility (the “2017 Bridge Facility”) with KeyBank. The Company drew $44.5 million to fund a portion of the purchase price of Rockledge Apartments and $21.4 million to fund a portion of the BH Buyout. The 2017 Bridge Facility is a full-term, interest-only facility with an initial four-month term (see below) and is guaranteed by the Company. Interest accrues on the 2017 Bridge Facility at an interest rate of one-month LIBOR plus 3.75%. In July 2017, the Company used proceeds from the sale of Regatta Bay to pay down $11.3 million on the 2017 Bridge Facility. In October 2017, the Company used proceeds from the sale of the NAVA Portfolio to pay down approximately $46.0 million on the 2017 Bridge Facility, bringing the outstanding balance to approximately $8.6 million, and also extended the maturity date to March 31, 2018. In February 2018, the Company used proceeds from the sale of Timberglen to pay the remaining $8.6 million outstanding on the 2017 Bridge Facility, which retired the bridge facility (see Note 13). The credit and bridge facilities agreements contain customary provisions with respect to events of default, covenants and borrowing conditions. Certain prepayments may be required upon a breach of covenants or borrowing conditions. As of December 31, 2017, the Company believes it is in compliance with all provisions of the agreements. $300 Million Credit Facility . On June 6, 2016, the Company, through certain subsidiaries of the OP, entered into a $200.0 million credit facility, which was expanded to $300.0 million (the “$300 Million Credit Facility”) during the fourth quarter of 2016 to acquire three properties. The $300 Million Credit Facility was cross-collateralized by the following 12 properties: Arbors on Forest Ridge, Cutter’s Point, Eagle Crest, Silverbrook, Timberglen, Edgewater at Sandy Springs, Beechwood Terrace, Willow Grove, Woodbridge, Venue at 8651, Old Farm and Stone Creek at Old Farm. On June 30, 2017, in connection with the Freddie Refinance, the Company repaid and retired the $300 Million Credit Facility. The refinancing of this existing credit facility debt did not incur prepayment penalties. 2016 Bridge Facility . On December 29, 2016, the Company, through the OP, entered into a $30.0 million bridge facility (the “2016 Bridge Facility”) with KeyBank and drew $30.0 million to fund a portion of the purchase price of Old Farm and Stone Creek at Old Farm. In April 2017, the Company paid down the entire $30.0 million of principal on the 2016 Bridge Facility, which was funded with its share of the proceeds, net of distributions to noncontrolling interests, from properties the Company sold in April 2017. The 2016 Bridge Facility was retired on April 28, 2017. Deferred Financing Costs The Company defers costs incurred in obtaining financing and amortizes the costs over the terms of the related loans using the straight-line method, which approximates the effective interest method. Deferred financing costs, net of amortization, are recorded as a reduction from the related debt on the Company’s consolidated balance sheets. Upon repayment of or in conjunction with a material change in the terms of the underlying debt agreement, any unamortized costs are charged to loss on extinguishment of debt and modification costs (see “Loss on Extinguishment of Debt and Modification Costs” below). For the years ended December 31, 2017, 2016 and 2015, the Company wrote-off deferred financing costs of $1.0 million, $0.7 million and $0, respectively, which is included in loss on extinguishment of debt and modification costs on the combined consolidated statements of operations and comprehensive income (loss). Amortization of deferred financing costs of $2.0 million, $1.4 million and $1.1 million is included in interest expense on the combined consolidated statements of operations and comprehensive income (loss) for the years ended December 31, 2017, 2016 and 2015, respectively. Loss on Extinguishment of Debt and Modification Costs Upon repayment of or in conjunction with a material change (i.e. a 10% or greater difference in the cash flows between instruments) in the terms of an underlying debt agreement, the Company writes off any unamortized deferred financing costs related to the original debt. Loss on extinguishment of debt and modification costs also includes prepayment penalties incurred on the early repayment of debt and costs incurred in a debt modification that are not capitalized as deferred financing costs. Schedule of Debt Maturities The aggregate scheduled maturities, including amortizing principal payments, of total debt for the next five calendar years subsequent to December 31, 2017 are as follows (in thousands): Operating Properties Held For Sale Properties Credit and Bridge Facilities Total 2018 $ 13,352 $ 219 $ 38,597 $ 52,168 2019 2,448 232 — 2,680 2020 2,483 236 — 2,719 2021 2,531 247 — 2,778 2022 11,422 12,666 — 24,088 Thereafter 699,342 17,226 — 716,568 Total $ 731,578 $ 30,826 $ 38,597 $ 801,001

Fair Value of Derivative and Fi

Fair Value of Derivative and Financial Instruments	12 Months Ended
	Dec. 31, 2017
Fair Value Disclosures [Abstract]
Fair Value Measures and Derivative Financial Instruments	7. Fair Value of Derivatives and Financial Instruments Fair value measurements are determined based on the assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, FASB ASC 820, Fair Value Measurement and Disclosures • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. • Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals. • Level 3 inputs are the unobservable inputs for the asset or liability, which are typically based on an entity’s own assumption, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on input from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company utilizes independent third parties to perform the allocation of value analysis for each property acquisition and to perform the market valuations on its derivative financial instruments and has established policies, as described above, processes and procedures intended to ensure that the valuation methodologies for investments and derivative financial instruments are fair and consistent as of the measurement date. Derivative Financial Instruments and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company may enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash payments principally related to the Company’s borrowings. In order to minimize counterparty credit risk, the Company enters into and expects to enter into hedging arrangements only with major financial institutions that have high credit ratings. The Company utilizes an independent third party to perform the market valuations on its derivative financial instruments. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The fair values of interest rate caps are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both the Company’s own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of the Company’s derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. 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 the Company’s 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 determined that the significance of the impact of the credit valuation adjustments made to its derivative contracts, which determination was based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all of the Company’s derivatives held as of December 31, 2017 and 2016 were classified as Level 2 of the fair value hierarchy. The Company’s main objective in using interest rate derivatives is to add stability to interest expense related to floating rate debt. To accomplish this objective, the Company primarily uses interest rate swaps and caps as part of its interest rate risk management strategy. Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The interest rate swaps have terms ranging from four to five years. Interest rate caps involve the receipt of variable-rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. The interest rate caps have terms ranging from three to four years. During the years ended December 31, 2017, 2016 and 2015, such derivatives were used to hedge the variable cash flows associated with a majority of the Company’s floating rate debt. The interest rate cap agreements the Company has entered into effectively cap one-month LIBOR on $273.5 million of the Company’s floating rate mortgage indebtedness at a weighted average rate of 4.26%. The effective portion of changes in the fair value of derivative financial instruments that are designated as cash flow hedges is recorded in other comprehensive income (loss) (“OCI”) and is subsequently reclassified into net income (loss) in the period that the hedged forecasted transaction affects earnings. Amounts reported in OCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s floating rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in net income (loss) as interest expense. During the years ended December 31, 2017 and 2016, the Company recorded approximately $0.3 million and $1.7 million, respectively, of gain related to the ineffective portion of changes in the fair value of its derivatives designated as cash flow hedges, which is recorded as a reduction to interest expense on the accompanying combined consolidated statements of operations and comprehensive income (loss). During the year ended December 31, 2015, the Company recorded no ineffectiveness in earnings attributable to derivatives designated as cash flow hedges. In order to fix a portion of, and mitigate the risk associated with, the Company’s floating rate indebtedness (without incurring substantial prepayment penalties or defeasance costs typically associated with fixed rate indebtedness when repaid early or refinanced), the Company, through the OP, has entered into seven interest rate swap transactions with KeyBank (the “Counterparty”) with a combined notional amount of $650.0 million. The interest rate swaps the Company has entered into effectively replace the floating interest rate (one-month LIBOR) with respect to that amount with a weighted average fixed rate of 1.3388%. The Company has designated these interest rate swaps as cash flow hedges of interest rate risk. As of December 31, 2017, the Company had the following outstanding interest rate swaps that were designated as cash flow hedges of interest rate risk (dollars in thousands): Effective Date Termination Date Notional Fixed Rate (1) July 1, 2016 June 1, 2021 $ 100,000 1.1055 % July 1, 2016 June 1, 2021 100,000 1.0210 % July 1, 2016 June 1, 2021 100,000 0.9000 % September 1, 2016 June 1, 2021 100,000 0.9560 % April 1, 2017 April 1, 2022 100,000 1.9570 % May 1, 2017 April 1, 2022 50,000 1.9610 % July 1, 2017 July 1, 2022 100,000 1.7820 % $ 650,000 1.3388 % (2) (1) The floating rate option for the interest rate swaps is one-month LIBOR.

The redemption value is based on the fair value of the Company’s common stock at the redemption date, and therefore, is calculated based on the fair value of the Company’s common stock at the balance sheet date. Since the valuation is based on observable inputs such as quoted prices for similar instruments in active markets, redeemable noncontrolling interests in the OP are classified as Level 2 if they are adjusted to their redemption value. Financial Instruments Not Carried at Fair Value At December 31, 2017 and 2016, the fair values of cash and cash equivalents, restricted cash, accounts receivable, prepaid assets, accounts payable and other accrued liabilities, accrued real estate taxes payable, accrued interest payable, security deposits and prepaid rent approximated their carrying values because of the short term nature of these instruments. The estimated fair values of other financial instruments were determined by the Company using available market information and appropriate valuation methodologies. Considerable judgment is necessary to interpret market data and develop estimated fair values. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company would realize on the disposition of the financial instruments. The use of different market assumptions or estimation methodologies may have a material effect on the estimated fair value amounts. Long-term indebtedness is carried at amounts that reasonably approximate their fair value. In calculating the fair value of its long-term indebtedness, the Company used interest rate and spread assumptions that reflect current credit worthiness and market conditions available for the issuance of long-term debt with similar terms and remaining maturities. These financial instruments utilize Level 2 inputs. Real estate assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In such cases, the Company will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value. There can be no assurance that the estimates discussed herein, using Level 3 inputs, are indicative of the amounts the Company could realize on disposition of the real estate asset. For the years ended December 31, 2017, 2016 and 2015, the Company did not record any impairment charges related to real estate assets.

Equity [Abstract]
Stockholders' Equity	8. Stockholders’ Equity Common Stock The Company began operations on March 31, 2015 as a result of the Spin-Off. During the year ended December 31, 2017, the Company issued 110,257 shares of common stock pursuant to its long-term incentive plan and retired 354,517 shares of common stock it had repurchased pursuant to its share repurchase program (see “Share Repurchase Program” and “Long Term Incentive Plan” below). As of December 31, 2017, the Company had 21,049,565 shares of common stock, $0.01 par value per share, issued and outstanding. Share Repurchase Program On June 15, 2016, the Board authorized the repurchase by the Company of up to $30.0 million of its common stock, $0.01 par value per share. This authorization expires on June 15, 2018. The Company may utilize various methods to effect the repurchases, and the timing and extent of the repurchases will depend upon several factors, including market and business conditions, regulatory requirements and other corporate considerations, including whether the Company’s common stock is trading at a significant discount to net asset value per share. Repurchases under this program may be discontinued at any time. During the year ended December 31, 2017, the Company repurchased 104,361 shares of its common stock, $0.01 par value per share, at a total cost of approximately $2,435,000, or $23.33 per share. As of December 31, 2017, the Company had repurchased 354,517 shares of its common stock, $0.01 par value per share, at a total cost of approximately $7,022,000, or $19.81 per share. Treasury Stock From time to time, in accordance with the Company’s share repurchase program, the Company may repurchase shares of its common stock in the open market. Until any such shares are retired, the cost of the shares is included in common stock held in treasury at cost on the consolidated balance sheet. The number of shares of common stock classified as treasury shares reduces the number of shares of the Company’s common stock outstanding and, accordingly, are considered in the weighted average number of shares outstanding during the period. During the year ended December 31, 2017, the Company retired 354,517 shares of its common stock held in treasury. As of December 31, 2017 and 2016, the Company had 0 shares and 250,156 shares, respectively, of common stock held in treasury. Long Term Incentive Plan On June 15, 2016, the Company’s stockholders approved a long-term incentive plan (the “2016 LTIP”) and the Company filed a registration statement on Form S-8 registering 2,100,000 shares of common stock, $0.01 par value per share, which the Company may issue pursuant to the 2016 LTIP. The 2016 LTIP authorizes the compensation committee of the Board to provide equity-based compensation in the form of stock options, appreciation rights, restricted shares, restricted stock units, performance shares, performance units and certain other awards denominated or payable in, or otherwise based on, the Company’s common stock or factors that may influence the value of the Company’s common stock, plus cash incentive awards, for the purpose of providing the Company’s directors, officers and other key employees (and those of the Adviser and the Company’s subsidiaries), the Company’s non-employee directors, and potentially certain non-employees who perform employee-type functions, incentives and rewards for performance. Restricted Stock Units . Under the 2016 LTIP, restricted stock units may be granted to the Company’s directors, officers and other key employees (and those of the Adviser and the Company’s subsidiaries) and typically vest over a three to four year period for officers and annually for directors. Beginning on the date of grant, restricted stock units earn dividends that are payable in cash on the vesting date. On August 11, 2016, pursuant to the 2016 LTIP, the Company granted 209,797 restricted stock units to its directors and officers. On March 16, 2017, pursuant to the 2016 LTIP, the Company granted 219,802 restricted stock units to its directors and officers. The following table includes the number of restricted stock units granted, vested, forfeited and outstanding as of December 31, 2017: 2017 Number of Units Weighted Average Grant Date Fair Value Outstanding January 1, 209,797 $ 19.20 Granted 219,802 22.57 Vested (110,257 ) 19.20 Forfeited — — Outstanding December 31, 319,342 (1) $ 21.52 (1) 49,768 restricted stock units vest in August 2018 and 49,772 restricted stock units vest in August 2019. 80,742 restricted stock units vest in March 2018 and 69,530 restricted stock units vest in each of March 2019 and March 2020. As of December 31, 2017, the Company had issued 110,257 shares of common stock under the 2016 LTIP. For the years ended December 31, 2017 and 2016, the Company recognized approximately $3.1 million and $0.8 million, respectively, of equity-based compensation expense related to grants of restricted stock units, which is included in corporate general and administrative expenses on the combined consolidated statements of operations and comprehensive income (loss). As of December 31, 2017, the Company had recognized a liability of approximately $0.3 million related to dividends earned on restricted stock units that are payable in cash upon vesting.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	9. Earnings (Loss) Per Share Basic earnings (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of shares of the Company’s common stock outstanding, which is adjusted for shares classified as treasury shares during the period and excludes any unvested restricted stock units issued pursuant to the 2016 LTIP. Diluted earnings (loss) per share is computed by adjusting basic earnings (loss) per share for the dilutive effect of the assumed vesting of restricted stock units. During periods of net loss, the assumed vesting of restricted stock units is anti-dilutive and is not included in the calculation of earnings (loss) per share. The effect of the conversion of OP Units held by noncontrolling limited partners is not reflected in the computation of basic and diluted earnings (loss) per share, as they are exchangeable for common stock on a one-for-one basis. The income (loss) allocable to such units is allocated on this same basis and reflected as net income attributable to redeemable noncontrolling interests in the Operating Partnership in the accompanying combined consolidated statements of operations and comprehensive income (loss). As such, the assumed conversion of these units would have no net impact on the determination of diluted earnings (loss) per share. See Note 10 for additional information. The following table sets forth the computation of basic and diluted earnings (loss) per share for the periods presented (in thousands, except per share amounts): For the Year Ended December 31, 2017 2016 2015 Numerator for earnings (loss) per share: Net income (loss) $ 56,359 $ 25,888 $ (10,992 ) Net income (loss) attributable to noncontrolling interests 2,836 4,006 (160 ) Net income attributable to redeemable noncontrolling interests in the Operating Partnership 149 — — Net income (loss) attributable to common stockholders $ 53,374 $ 21,882 $ (10,832 ) Denominator for earnings (loss) per share: Weighted average common shares outstanding 21,057 21,232 21,294 Denominator for basic earnings (loss) per share 21,057 21,232 21,294 Weighted average unvested restricted stock units 342 82 — Denominator for diluted earnings per share 21,399 21,314 21,294 Earnings (loss) per weighted average common share: Basic $ 2.53 $ 1.03 $ (0.51 ) Diluted $ 2.49 $ 1.03 $ (0.51 )

Noncontrolling Interest [Abstract]
Noncontrolling Interests	10. Noncontrolling Interests Redeemable Noncontrolling Interests in the OP Interests in the OP held by limited partners are represented by OP Units. Net income (loss) is allocated to holders of OP Units based upon net income (loss) attributable to common stockholders and the weighted average number of OP Units outstanding to total common shares plus OP Units outstanding during the period. Capital contributions, distributions, and profits and losses are allocated to OP Units in accordance with the terms of the partnership agreement of the OP. Each time the OP distributes cash to the Company, outside limited partners of the OP receive their pro-rata share of the distribution. On June 30, 2017, the Company and the OP entered into a contribution agreement (the “Contribution Agreement”) with BH Equities, LLC and its affiliates (collectively, “BH Equity”), whereby the Company purchased 100% of the joint venture interests in the Portfolio owned by BH Equity, representing approximately 8.4% ownership in the Portfolio (the “BH Buyout”), for total consideration of approximately $51.7 million (the “Purchase Amount”). The Purchase Amount consisted of approximately $49.7 million in cash that was paid on June 30, 2017 and 73,233 OP Units (initially valued at $2.0 million) that were issued on August 1, 2017. The number of OP Units issued was calculated by dividing $2.0 million by the midpoint of the range of the Company’s net asset value as publicly disclosed in connection with the Company’s release of its second quarter of 2017 earnings results, which was $27.31 per share. The Company financed the cash portion of the Purchase Amount with $21.4 million of proceeds from the 2017 Bridge Facility, $16.3 million of proceeds from the Freddie Refinance, $11.0 million of proceeds from the $30 Million Credit Facility and $1.0 million of cash on hand. In connection with the issuance of OP Units to BH Equity on August 1, 2017, the Company and the OP amended the partnership agreement of the OP (the “Amendment”). Pursuant to the Amendment, limited partners holding OP Units have the right to cause the OP to redeem their units at a redemption price equal to and in the form of the Cash Amount (as defined in the partnership agreement of the OP), provided that such OP Units have been outstanding for at least one year. The Company, through the OP GP, as the general partner of the OP may, in its sole discretion, purchase the OP Units by paying to the limited partner either the Cash Amount or the REIT Share Amount (one share of common stock of the Company for each OP Unit), as defined in the partnership agreement of the OP. Notwithstanding the foregoing, a limited partner will not be entitled to exercise its redemption right to the extent the issuance of the Company’s common stock to the redeeming limited partner would (1) be prohibited, as determined in the Company’s sole discretion, under the Company’s charter or (2) cause the acquisition of common stock by such redeeming limited partner to be "integrated" with any other distribution of the Company’s common stock for purposes of complying with the Securities Act of 1933, as amended. Accordingly, the Company records the OP Units held by noncontrolling limited partners outside of permanent equity and reports the OP Units at the greater of their carrying value or their redemption value using the Company’s stock price at each balance sheet date. The following table sets forth the redeemable noncontrolling interests in the OP for the year ended December 31, 2017 (in thousands): Redeemable noncontrolling interests in the OP, December 31, 2016 $ — Issuance of redeemable noncontrolling interests in the OP 2,000 Net income attributable to redeemable noncontrolling interests in the OP 149 Other comprehensive income attributable to redeemable noncontrolling interests in the OP 17 Contributions from redeemable noncontrolling interests in the OP 56 Distributions to redeemable noncontrolling interests in the OP (87 ) Redeemable noncontrolling interests in the OP, December 31, 2017 $ 2,135 Noncontrolling Interests Noncontrolling interests have in the past and may in the future be comprised of joint venture partners’ interests in joint ventures the Company consolidates. When applicable, the Company reports its joint venture partners’ interests in its consolidated joint ventures and other subsidiary interests held by third parties as noncontrolling interests. The Company records these noncontrolling interests at their initial fair value, adjusting the basis prospectively for their share of the respective consolidated investment’s net income or loss, equity contributions, return of capital, and distributions. Generally, these noncontrolling interests are not redeemable by the equity holders and are presented as part of permanent equity. Income and losses are allocated to the noncontrolling interest holder based on its economic ownership percentage. During the period ended June 30, 2017, prior to the BH Buyout, the Company purchased 100% of the noncontrolling interests in three of its joint ventures for approximately $2.0 million. On June 30, 2017, in connection with the BH Buyout, the Company purchased 100% of the outstanding noncontrolling interests in its remaining joint ventures for approximately $51.7 million. On June 30, 2017, prior to the BH Buyout, the carrying value of such noncontrolling interests was approximately $20.5 million. On June 30, 2017, the Company eliminated the carrying value of such noncontrolling interests on its consolidated balance sheet. The remaining $31.2 million of the Purchase Amount resulted in a reduction to additional paid-in capital on the Company’s consolidated balance sheet. In connection with the Contribution Agreement, the Company fully indemnified BH Equity on all non-recourse carve out guarantees it had previously provided for mortgage indebtedness secured by certain properties in the Portfolio. In consideration of the guarantees previously provided by BH Equity, it was entitled to an additional profit interest in each entity (the “Total Promote”) such that distributions were to be made to the members of the entity pro rata in proportion to their relative percentage interests until the members received an internal rate of return equal to 13%. Then, the proportion of distributions changed to a predetermined allocation according to the agreements between each entity and BH Equity. The Total Promote due by the Company to BH Equity was relinquished in connection with the BH Buyout.

Related Party Transactions [Abstract]
Related Party Transactions	11. Related Party Transactions Fees and Reimbursements to BH and its Affiliates The Company has entered into management agreements with BH Management Services, LLC (“BH”), the Company’s property manager and an independently owned third party, who manages the Company’s properties and supervises the implementation of the Company’s value-add program. BH is an affiliate of BH Equity, who was a noncontrolling interest member of the Company’s joint ventures prior to the BH Buyout on June 30, 2017. Through BH Equity’s noncontrolling interests in such joint ventures, BH Equity was deemed to be a related party. With the completion of the BH Buyout, BH Equity is no longer deemed to be a related party. BH Equity became a noncontrolling limited partner of the OP upon execution of the Amendment. BH and its affiliates do not have common ownership in any joint venture with the Company’s Adviser; there is also no common ownership between BH and its affiliates and the Company’s Adviser. The property management fee paid to BH is approximately 3% of the monthly gross income from each property managed. Currently, BH manages all of the Company’s properties. Additionally, the Company may pay BH certain other fees, including: (1) a fee of $15-25 per unit for the one-time setup and inspection of properties, (2) a construction supervision fee of 5-6% of total project costs, which is capitalized, (3) acquisition fees and due diligence costs reimbursements, and (4) other owner approved fees at $55 per hour. BH also acts as a paymaster for the properties and is reimbursed at cost for various operating expenses it pays on behalf of the properties. The following is a summary of fees that the properties incurred to BH and its affiliates, as well as reimbursements paid to BH from the properties for various operating expenses, for the years ended December 31, 2017, 2016 and 2015 (in thousands): For the Year Ended December 31, 2017 2016 2015 Fees incurred Property management fees (1) $ 4,330 $ 3,983 $ 3,501 Construction supervision fees (2) 869 885 1,549 Acquisition fees (3) 675 589 2,048 Reimbursements Payroll and benefits (4) 15,344 15,586 14,903 Other reimbursements (5) 1,982 2,078 1,179 (1) Included in property management fees on the combined consolidated statements of operations and comprehensive income (loss). (2) Capitalized on the consolidated balance sheets and reflected in buildings and improvements. (3) Includes due diligence costs. Acquisition fees incurred prior to October 1, 2016 are included in acquisition costs on the combined consolidated statements of operations and comprehensive income (loss). Acquisition fees incurred for the period beginning on October 1, 2016 are capitalized to real estate assets on the consolidated balance sheets. (4) Included in property operating expenses on the combined consolidated statements of operations and comprehensive income (loss). (5) Includes property operating expenses such as repairs and maintenance costs and certain property general and administrative expenses, which are included on the combined consolidated statements of operations and comprehensive income (loss). Asset Management Fee Until the BH Buyout on June 30, 2017, in accordance with the operating agreement of each entity that owns the properties, the Company earned an asset management fee for services provided in connection with monitoring the operations of the properties. The asset management fee was equal to 0.5% per annum of the aggregate effective gross income of the properties, as defined in each of the operating agreements. For the years ended December 31, 2017, 2016 and 2015, the properties incurred asset management fees to the Company of approximately $0.4 million, $0.7 million, and $0.6 million, respectively. Since the fees were paid to the Company (and not the Adviser) by consolidated properties, they have been eliminated in consolidation. However, because the Company’s previous joint venture partners owned a portion of each of a majority of the properties in the Portfolio, prior to the Company’s purchase of 100% of their joint venture interests, they absorbed their pro rata share of the asset management fee. This amount is reflected on the combined consolidated statements of operations and comprehensive income (loss) in the net income (loss) attributable to noncontrolling interests. Advisory and Administrative Fee Prior to the Spin-Off, the predecessor paid NexPoint Advisors, L.P., an affiliate of the Adviser, an annual advisory fee, paid monthly, in an amount equal to 1.00% of the average weekly value of the predecessor’s “Managed Assets.” The predecessor’s Managed Assets were an amount equal to the total assets of the predecessor, including any form of leverage, minus all accrued expenses incurred in the normal course of operations, but not excluding any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other preference securities, (iii) the reinvestment of collateral received for securities loaned in accordance with the predecessor’s investment objectives and policies, and/or (iv) any other means. Additionally, the predecessor paid NexPoint Advisors, L.P. an administrative fee for services to the predecessor. The administrative fee was payable monthly, in an amount equal to 0.20% of the average weekly value of the predecessor’s Managed Assets. The advisory and administrative fees were paid by the predecessor on behalf of the Company. Following the Spin-Off and in accordance with the Advisory Agreement, the Company pays the Adviser an advisory fee equal to 1.00% of the Average Real Estate Assets (as defined below). The duties performed by the Company’s Adviser under the terms of the Advisory Agreement include, but are not limited to: providing daily management for the Company, selecting and working with third party service providers, managing the Company’s properties or overseeing the third party property manager, formulating an investment strategy for the Company and selecting suitable properties and investments, managing the Company’s outstanding debt and its interest rate exposure through derivative instruments, determining when to sell assets, and managing the value-add program or overseeing a third party vendor that implements the value-add program. “Average Real Estate Assets” means the average of the aggregate book value of Real Estate Assets before reserves for depreciation or other non-cash reserves, computed by taking the average of the book value of real estate assets at the end of each month (1) for which any fee under the Advisory Agreement is calculated or (2) during the year for which any expense reimbursement under the Advisory Agreement is calculated. “Real Estate Assets” is defined broadly in the Advisory Agreement to include, among other things, investments in real estate-related securities and mortgages and reserves for capital expenditures (the value-add program). The advisory fee is payable monthly in arrears in cash, unless the Adviser elects, in its sole discretion, to receive all or a portion of the advisory fee in shares of common stock, subject to certain limitations. In accordance with the Advisory Agreement, the Company also pays the Adviser an administrative fee equal to 0.20% of the Average Real Estate Assets. The administrative fee is payable monthly in arrears in cash, unless the Adviser elects, in its sole discretion, to receive all or a portion of the administrative fee in shares of common stock, subject to certain limitations. The advisory and administrative fees paid to the Adviser on the Contributed Assets (as defined below) are subject to an annual cap of approximately $5.4 million (the “Contributed Assets Cap”) (see “Expense Cap” below). Pursuant to the terms of the Advisory Agreement, the Company will reimburse the Adviser for all documented Operating Expenses and Offering Expenses it incurs on behalf of the Company. “Operating Expenses” include legal, accounting, financial and due diligence services performed by the Adviser that outside professionals or outside consultants would otherwise perform, the Company’s pro rata share of rent, telephone, utilities, office furniture, equipment, machinery and other office, internal and overhead expenses of the Adviser required for the Company’s operations, and compensation expenses under the 2016 LTIP. Operating Expenses do not include expenses for the advisory and administrative services described in the Advisory Agreement. Certain Operating Expenses, such as the Company’s ratable share of rent, telephone, utilities, office furniture, equipment, machinery and other office, internal and overhead expenses incurred by the Adviser or its affiliates that relate to the operations of the Company, may be billed monthly to the Company under a shared services agreement. “Offering Expenses” include all expenses (other than underwriters’ discounts) in connection with an offering, including, without limitation, legal, accounting, printing, mailing and filing fees and other documented offering expenses. For the years ended December 31, 2017, 2016, and 2015, the Adviser did not bill any Operating Expenses or Offering Expenses to the Company and any such expenses the Adviser incurred during the periods are considered to be permanently waived. Expense Cap Pursuant to the terms of the Advisory Agreement, expenses paid or incurred by the Company for advisory and administrative fees payable to the Adviser and Operating Expenses will not exceed 1.5% of Average Real Estate Assets per calendar year (or part thereof that the Advisory Agreement is in effect (the “Expense Cap”)). The Expense Cap does not limit the reimbursement of expenses related to Offering Expenses. The Expense Cap also does not apply to legal, accounting, financial, due diligence and other service fees incurred in connection with mergers and acquisitions, extraordinary litigation or other events outside the Company’s ordinary course of business or any out-of-pocket acquisitions or due diligence expenses incurred in connection with the acquisition or disposition of real estate assets. Also, advisory and administrative fees are further limited on Contributed Assets to approximately $5.4 million in any calendar year. Contributed Assets refers to all Real Estate Assets contributed to the Company as part of the Spin-Off. The Contributed Assets Cap is not reduced for dispositions of such assets subsequent to the Spin-Off. Advisory and administrative fees on New Assets are not subject to the above limitation and are based on an annual rate of 1.2% on Average Real Estate Assets, but are subject to the Expense Cap. New Assets are all Real Estate Assets that are not Contributed Assets. For the years ended December 31, 2017, 2016 and 2015, the Company incurred advisory and administrative fees of $7.4 million, $6.8 million, and $5.6 million, respectively. The amount paid for the years ended December 31, 2017, 2016 and 2015 represents the maximum fee allowed on Contributed Assets (as defined in the Advisory Agreement) under the Advisory Agreement plus approximately $2.0 million, $1.4 million and $0.2 million, respectively, of advisory and administrative fees incurred on New Assets (as defined in the Advisory Agreement). The allocation of advisory and administrative fees prior to the Spin-Off is based on the terms of the advisory agreement between the Company’s predecessor and its advisor, NexPoint Advisors, L.P. In management’s estimation, the allocation methodologies used are reasonable and result in a reasonable allocation of operating costs borne by the Company’s predecessor; however, these allocations may not be indicative of the cost of future operations or the amount of future allocations. These fees are reflected on the combined consolidated statements of operations and comprehensive income (loss) in advisory and administrative fees. The increase in advisory and administrative fees on New Assets between both the periods was due to the acquisition of additional properties classified as New Assets after the Spin-Off, for which the Adviser has elected to receive fees on, and the timing of the acquisitions (the Company acquired two properties in August 2015, one property in October 2015, one property in July 2016 and one property in October 2016 that the Adviser elected to receive advisory and administrative fees on).

For the year ended December 31, 2016, the Adviser elected to voluntarily waive the advisory and administrative fees incurred on the two properties acquired in December 2016, which are considered to be permanently waived for the period.

Commitments and Contingencies	12. Commitments and Contingencies Commitments In the normal course of business, the Company enters into various rehabilitation construction related purchase commitments with parties that provide these goods and services. In the event the Company were to terminate rehabilitation construction services prior to the completion of projects, the Company could potentially be committed to satisfy outstanding or uncompleted purchase orders with such parties. As of December 31, 2017, management does not anticipate any material deviations from schedule or budget related to rehabilitation projects currently in process. Contingencies In the normal course of business, the Company is subject to claims, lawsuits, and legal proceedings. While it is not possible to ascertain the ultimate outcome of all such matters, management believes that the aggregate amount of such liabilities, if any, in excess of amounts provided or covered by insurance, will not have a material adverse effect on the consolidated balance sheets or combined consolidated statements of operations and comprehensive income (loss) of the Company. The Company is not involved in any material litigation nor, to management’s knowledge, is any material litigation currently threatened against the Company or its properties or subsidiaries. The Company is not aware of any environmental liability with respect to the properties that could have a material adverse effect on the Company’s business, assets, or results of operations. However, there can be no assurance that such a material environmental liability does not exist. The existence of any such material environmental liability could have an adverse effect on the Company’s results of operations and cash flows.

Summary of Significant Accoun22

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Predecessor	Predecessor With the exception of a nominal amount of initial cash funded at inception, the Company did not own any assets prior to March 31, 2015. The business and operations of the Company prior to March 31, 2015 occurred under the predecessor. The predecessor included all of the properties in the Portfolio that were held directly or indirectly by NREO prior to the Spin-Off that occurred on March 31, 2015. However, the Company’s combined consolidated financial statements reflect operations of the predecessor through March 31, 2015 as if they were incurred by the Company. The predecessor was determined in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). References throughout these combined consolidated financial statements to the “Company”, “we”, or “our”, include the activity of the predecessor defined above.
Basis of Accounting	Basis of Accounting The accompanying combined consolidated financial statements have been prepared according to the rules and regulations of the SEC. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted according to such rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments and eliminations necessary for the fair presentation of the Company’s financial position as of December 31, 2017, and results of operations for the years ended December 31, 2017, 2016 and 2015 have been included. Such adjustments are normal and recurring in nature. The accompanying combined consolidated financial statements are presented in accordance with GAAP. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the dates of the combined consolidated financial statements and the amounts of revenues and expenses during the reporting periods. Actual amounts realized or paid could differ from those estimates. All significant intercompany accounts and transactions have been eliminated in consolidation. There have been no significant changes to the Company’s significant accounting policies during the year ended December 31, 2017.
Principles of Consolidation	Principles of Consolidation The Company accounts for subsidiary partnerships, joint ventures and other similar entities in which it holds an ownership interest in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation
Revenue Recognition	Revenue Recognition The Company’s primary operations consist of rental income earned from its residents under lease agreements typically with terms of one year or less. Rental income is recognized when earned. This policy effectively results in income recognition on the straight-line method over the related terms of the leases. Resident reimbursements and other income consist of charges billed to residents for utilities, carport and garage rental, and pets, administrative, application and other fees and are recognized when earned.
Real Estate Investments	Real Estate Investments Upon acquisition of a property, the purchase price and related acquisition costs (“total consideration”) are allocated to land, buildings, improvements, furniture, fixtures, and equipment, and intangible lease assets in accordance with FASB ASC 805, Business Combinations Clarifying the Definition of a Business (Topic 805) The allocation of total consideration, which is determined using inputs that are classified within Level 3 of the fair value hierarchy established by FASB ASC 820, Fair Value Measurement and Disclosures Real estate assets, including land, buildings, improvements, furniture, fixtures and equipment, and intangible lease assets are stated at historical cost less accumulated depreciation and amortization. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. Expenditures for improvements, renovations, and replacements are capitalized at cost. Real estate-related depreciation and amortization are computed on a straight-line basis over the estimated useful lives as described in the following table: Land Not depreciated Buildings 30 years Improvements 15 years Furniture, fixtures, and equipment 3 years Intangible lease assets 6 months Construction in progress includes the cost of renovation projects being performed at the various properties. Once a project is complete, the historical cost of the renovation is placed into service in one of the categories above depending on the type of renovation project and is depreciated over the estimated useful lives as described in the table above. Real estate assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In such cases, the Company will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value. The Company periodically classifies real estate assets as held for sale when certain criteria are met, in accordance with GAAP. At that time, the Company presents the net real estate assets and the net debt associated with the real estate held for sale separately in its consolidated balance sheet, and the Company ceases recording depreciation and amortization expense related to that property. Real estate held for sale is reported at the lower of its carrying amount or its estimated fair value less estimated costs to sell.
Reclassifications	Reclassifications Certain reclassifications have been made to amounts in the prior year combined consolidated statements of operations and comprehensive income (loss) to conform to current year presentations as a result of an accounting policy election to classify certain expenses incurred in connection with the extinguishment or modification of debt separately from interest expense. These expenses are recorded in loss on extinguishment of debt and modification costs on the combined consolidated statements of operations and comprehensive income (loss). As a result, for the years ended December 31, 2016 and 2015, interest expense decreased (and loss on extinguishment of debt and modification costs increased) by approximately $1.7 million and $0.7 million, respectively. See Note 6 for additional information.
Reportable Segment	Reportable Segment Substantially all of the Company’s net income (loss) is from investments in real estate properties within the multifamily sector that the Company owns through LLCs. The Company evaluates operating performance on an individual property level and views its real estate assets as one industry segment and, accordingly, its properties are aggregated into one reportable segment.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and expects to continue to qualify as a REIT. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement to distribute annually at least 90% of its “REIT taxable income,” as defined by the Code, to its stockholders. As a REIT, the Company will be subject to federal income tax on its undistributed REIT taxable income and net capital gain and to a 4% nondeductible excise tax on any amount by which distributions it pays with respect to any calendar year are less than the sum of (1) 85% of its ordinary income, (2) 95% of its capital gain net income and (3) 100% of its undistributed income from prior years. The Company intends to operate in such a manner so as to qualify as a REIT, but no assurance can be given that the Company will operate in a manner so as to qualify as a REIT. Taxable income from certain non-REIT activities is managed through a TRS and is subject to applicable federal, state, and local income and margin taxes. The Company had no significant taxes associated with its TRS for the years ended December 31, 2017, 2016 and 2015. If the Company fails to meet these requirements, it could be subject to federal income tax on all of the Company’s taxable income at regular corporate rates for that year. The Company would not be able to deduct distributions paid to stockholders in any year in which it fails to qualify as a REIT. Additionally, the Company will also be disqualified from electing to be taxed as a REIT for the four taxable years following the year during which qualification was lost unless the Company is entitled to relief under specific statutory provisions. As of December 31, 2017, the Company believes it is in compliance with all applicable REIT requirements. The Company evaluates the accounting and disclosure of tax positions taken or expected to be taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” (greater than 50 percent probability) of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. The Company’s management is required to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions, which include federal and certain states. The Company has no examinations in progress and none are expected at this time. The Company recognizes its tax positions and evaluates them using a two-step process. First, the Company determines whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Second, the Company will determine the amount of benefit to recognize and record the amount that is more likely than not to be realized upon ultimate settlement. The Company had no material unrecognized tax benefit or expense, accrued interest or penalties as of December 31, 2017. The Company and its subsidiaries are subject to federal income tax as well as income tax of various state and local jurisdictions. The 2016 and 2015 tax years remain open to examination by tax jurisdictions to which the Company and its subsidiaries are subject. When applicable, the Company recognizes interest and/or penalties related to uncertain tax positions on its combined consolidated statements of operations and comprehensive income (loss).
Recent Accounting Pronouncements	Recent Accounting Pronouncements Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 13(a) of the Securities Exchange Act of 1934, as amended, for complying with new or revised accounting standards applicable to public companies. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company has elected to take advantage of this extended transition period. As a result of this election, the Company’s financial statements may not be comparable to companies that comply with public company effective dates for such new or revised standards.
