We also have assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

This opinion letter is based as to matters of law solely on the applicable provisions of the following, as currently in effect: (i) the Delaware Revised Uniform Limited Partnership Act; and (ii) the laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level). We express no opinion herein as to any other laws, statutes, ordinances, rules or regulations (and in particular, we express no opinion as to any effect that such other laws, statutes, ordinances, rules or regulations may have on the opinion expressed herein). As used herein, the term “Delaware Revised Uniform Limited Partnership Act” includes the statutory provisions contained therein, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Notes have been duly authorized on behalf of the Company, and that, following (i) receipt by the Company of the consideration therefor specified in the resolutions of the Board of Trustees of American Homes 4 Rent, a Maryland real estate investment trust (“AHR”), on behalf of the Company, adopted on October 12, 2017, January 22, 2018 and November 1, 2018 and the Underwriting Agreement (the “Agreement”) dated January 15, 2019, by and among the Company and J.P.

LLC, as representatives of the several underwriters named therein, and (ii) the due execution, authentication, issuance and delivery of the Notes pursuant to the terms of the Indenture and, upon its execution, the terms of the Supplemental Indenture, and as contemplated by the Prospectus Supplement, the Notes will constitute valid and binding obligations of the Company.

The opinion expressed above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and preferential transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the Notes are considered in a proceeding in equity or at law).

This opinion letter has been prepared for use in connection with the filing by AHR and the Company of a Current Report on Form 8-K on the date hereof (the “Form 8-K”), which Form 8-K will be incorporated by reference into the Registration Statement, and speaks as of the date hereof. We assume no obligation to advise of any changes in the foregoing subsequent to the delivery of this opinion letter.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Form 8-K, and to the reference to this firm under the caption “Legal Matters” in the Prospectus Supplement, which constitutes part of the Registration Statement.
