Ladies and Gentlemen:

We have acted as counsel to Global Medical REIT Inc., a Maryland corporation (the “Company”), in connection with the offer and sale of up to 3,105,000 shares of 7.50% Series A Cumulative Redeemable Preferred Stock of the Company, par value $0.001 per share (the “Series A Preferred Stock”), pursuant to a preliminary prospectus supplement dated September 12, 2017, and a final prospectus supplement dated September 12, 2017 (together with the preliminary prospectus supplement, the “Prospectus Supplement”), forming part of the Registration Statement on Form S-3 (File No. 333-217360) filed with the Securities and Exchange Commission on April 18, 2017, as amended through the date hereof (the “Registration Statement”). You have requested our opinion regarding certain U.S. federal income tax matters.

In connection with the opinions rendered in (a) and (b) below (together, the “Tax Opinion”), we have examined the following:

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

In connection with the opinions rendered below, we also have relied upon the correctness of the factual representations contained in the Officer’s Certificate. No facts have come to our attention that would cause us to question the accuracy and completeness of such factual representations. Furthermore, where such factual representations 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 individuals making such representations the relevant provisions of the Code, the applicable Regulations and published administrative interpretations thereof.

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

We will not review on a continuing basis the Company’s compliance with the documents or assumptions set forth above, or the factual 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 of the facts referred to in this letter or the Officer’s Certificate.

The foregoing Tax Opinion is based on current provisions of the Code, 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 Tax Opinion is 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 Tax Opinion 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.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name under the caption “Legal Matters” in the Prospectus Supplement. In giving this consent, we do not admit that we are in the category of persons whose consent is required by Section 7 of the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder by the Securities and Exchange Commission.
