Ladies and Gentlemen:

     We have acted as special counsel to Plymouth Opportunity REIT, Inc., a Maryland corporation (the “Company”), in connection with the Registration Statement on Form S-11 (File No. 333-173048) (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of 65,000,000 shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”). This opinion is being provided at your request in connection with the filing of the Registration Statement.

     In connection with this opinion, we have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable in connection with this opinion, including, without limitation, (i) the Company’s Articles of Incorporation, certified as of a recent date by the State Department of Assessments and Taxation of the State of Maryland (“SDAT”), (ii) the Company’s Form of Amended and Restated Articles of Incorporation, as filed as an exhibit to the Registration Statement and as will be filed by the Company with the SDAT prior to the issuance of any Shares under the Registration Statement, (iii) the Company’s Bylaws, (iv) the Registration Statement and (v) resolutions of the Company’s board of directors relating to the issuance and sale of the Common Stock and matters related thereto (“Resolutions”). In our examination we have assumed (without any independent investigation) the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies, the authenticity of originals of such copies and the authenticity of telegraphic or telephonic confirmations of public officials and others. As to facts material to our opinion, we have relied upon (without any independent investigation) certificates or telegraphic or telephonic confirmations of public officials and certificates, documents, statements and other information of the Company or its representatives
