Ladies and Gentlemen:

Reference is made to the Registration Statement on Form S-4, including amendments and exhibits thereto (the “Registration Statement”), for the proposed offer to exchange (the “Exchange Offer”) by Meritage Homes Corporation, a Maryland corporation (the “Company”), and each of the subsidiary guarantors listed on Schedule I attached hereto (collectively, the “Guarantors”), up to an aggregate of $175 million in principal amount of its 4.50% Senior Notes due 2018 that have been registered under the Securities Act of 1933, as amended (the “Securities Act” and such notes, the “Exchange Notes”), for a like principal amount of its outstanding unregistered 4.50% Senior Notes due 2018 (the “Outstanding Notes”) and the guarantees by the Guarantors of the Exchange Notes. The Outstanding Notes were issued, and the Exchange Notes are issuable, pursuant to an Indenture, dated March 13, 2013, by and among the Company, the Guarantors and Wells Fargo Bank, National Association, as Trustee (the “Indenture”).

Based on the foregoing, and subject to the qualifications and limitations set forth herein, we advise you that:

1. The Exchange Notes, assuming the due authorization, execution, authentication and delivery thereof by the Trustee, when delivered by the Company in accordance with the terms of the Indenture and in exchange for Outstanding Notes as contemplated in the Registration Statement, will be valid and legally binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms.
