Ladies and Gentlemen:

We have acted as tax counsel to Cherry Hill Mortgage Investment Corporation, a Maryland corporation (the “Company”), in connection with the preparation of a registration statement on Form S-11 (the “Registration Statement”), as filed with the Securities and Exchange Commission on March 13, 2013, as amended through the date hereof, with respect to the offer and sale of up to 7,475,000 shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”). You have requested our opinion regarding certain U.S. federal income tax matters.

In giving this opinion letter, we have examined the following:

1. the Registration Statement and the Prospectus filed as part of the Registration Statement;

2. the Company’s Charter;

3. the Amended and Restated Agreement of Limited Partnership of Cherry Hill Operating Partnership, LP (the “Operating Partnership”); and

4. such other documents as we have deemed necessary or appropriate for purposes of this opinion.

In connection with the opinions rendered below, we have assumed, with your consent, that:

1. each of the documents referred to above has been duly authorized, executed, and delivered; is authentic, if an original, or is accurate, if a copy; and has not been amended;

2. during its short taxable year ending December 31, 2013 and future taxable years, the Company will operate in a manner that will make the factual representations contained in a certificate, dated the date hereof and executed by a duly appointed officer of the Company (the “Officer’s Certificate”), true for such years;

3. the Company will not make any amendments to its organizational documents after the date of this opinion that would affect the Company’s qualification as a real estate investment trust (a “REIT”) for any taxable year; and

4. no action will be taken by the Company after the date hereof that would have the effect of altering the facts upon which the opinions set forth below are based.

In connection with the opinions rendered below, we also have relied upon the correctness of the factual representations contained in the Officer’s Certificate and the factual matters discussed in the Prospectus that relate to the Company’s status as a REIT. We are not aware of any facts that are inconsistent with the representations contained in the Officer’s Certificate. Where the factual representations in the Officer’s Certificate involve terms defined in the Internal Revenue Code of 1986, as amended (the “Code”), the Treasury regulations thereunder (the “Regulations”), published rulings of the Internal Revenue Service (the “Service”), or other relevant authority, we have reviewed with the individual making such representations the relevant provisions of the Code, the applicable Regulations, the published rulings of the Service, and other relevant authority.

Based solely on the documents and assumptions set forth above, the representations set forth in the Officer’s Certificate, and the factual matters discussed in the Prospectus under the caption “Material U.S. Federal Income Tax Considerations” (which is incorporated herein by reference), we are of the opinion that:

(a) commencing with its short taxable year ending on December 31, 2013, the Company will be organized in conformity with the requirements for qualification and taxation as a REIT pursuant to sections 856 through 860 of the Code, and the Company’s organization and proposed method of operation will enable it to qualify as a REIT under the Code for its short taxable year ending December 31, 2013 and thereafter; and

(b) the descriptions of the law and the legal conclusions contained in the Prospectus under the caption “Material U.S. Federal Income Tax Considerations” are correct in all material respects.

We will not review on a continuing basis the Company’s compliance with the documents or assumptions set forth above, or the representations set forth in the Officer’s Certificate. Accordingly, no assurance can be given that the actual results of the Company’s operations for any given taxable year will satisfy the requirements for qualification and taxation as a REIT. Although we have made such inquiries and performed such investigations as we have deemed necessary to fulfill our professional responsibilities as counsel, we have not undertaken an independent investigation of all the facts referred to in this opinion letter or the Officer’s Certificate.

The foregoing opinions are based on current provisions of the Code and the Regulations, published administrative interpretations thereof, and published court decisions. The Service has not issued Regulations or administrative interpretations with respect to various provisions of the Code relating to REIT qualification. No assurance can be given that the law will not change in a way that will prevent the Company from qualifying as a REIT.

The foregoing opinions are limited to the U.S. federal income tax matters addressed herein, and no other opinions are rendered with respect to other U.S. federal tax matters or to any issues arising under the tax laws of any other country, or any state or locality. We undertake no obligation to update the opinions expressed herein after the date of this letter. This opinion letter speaks only as of the date hereof. Except as provided in the next paragraph, this opinion letter may not be distributed, quoted in whole or in part or otherwise reproduced in any document, or filed with any governmental agency without our express written consent.
