Ladies and Gentlemen:

I am Vice President and Assistant Secretary of D.R. Horton, Inc., a Delaware corporation (the “Company”). The Company and certain direct and indirect wholly-owned subsidiaries of the Company (collectively, the “Guarantors”) have filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) a Registration Statement on Form S-3, File No. 333-162123 (the “Registration Statement”), and a prospectus and prospectus supplement with respect thereto, dated September 24, 2009 and April 25, 2012, respectively, in connection with the offering by the Company pursuant thereto of $350,000,000 aggregate principal amount of the Company’s 4.750% Senior Notes due 2017 (the “Notes”).

The Notes will be issued under an Indenture, to be dated as of May 1, 2012 (the “Base Indenture”), between the Company and American Stock Transfer & Trust Company, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, to be dated as of May 1, 2012, relating to the Notes (the “Supplemental Indenture” and together with the Base Indenture, the “Indenture”) between the Company, the Guarantors and the Trustee, and are guaranteed pursuant to the terms of the Indenture and the notation endorsed on the Notes by the Guarantors (the “Guarantees”) (the Indenture, the certificates evidencing the notes and the Guarantees are referred to collectively herein as the “Note Documents”).

In arriving at the opinions expressed below, I have examined originals, or copies certified or otherwise identified to my satisfaction as being true and complete copies of the originals, of the Base Indenture, the Supplemental Indenture, the Notes and the Guarantees and such other documents, corporate records, certificates of officers of public officials and other instruments as I have deemed necessary or advisable to enable me to render these opinions. In my examination, I have assumed, without independent investigation, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to me as originals and the conformity to original documents of all documents submitted to me as copies. As to any facts material to these opinions, I have relied to the extent I have deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company and the guarantors listed on Exhibit A hereto (the “Specified Guarantors”) and others.
