Re: Public Offering of Common Stock under Registration Statement on Form S-3 (File No. 333-281479)

Ladies and Gentlemen:

We are acting as counsel to NETSTREIT Corp., a Maryland corporation (the “Company”), in connection with the offering and sale of up to 12,627,000 shares (the “Shares”) of the Company’s common stock, $0.01 par value per share (the “Common Stock”), including 1,647,000 shares of Common Stock that may be sold pursuant to the underwriters’ option to purchase additional shares, pursuant to a prospectus supplement dated February 11, 2026 and the accompanying base prospectus dated August 12, 2024 (such documents, collectively, the “Prospectus”) that form part of the Company’s effective Registration Statement on Form S-3 (File No. 333-281479) (the “Registration Statement”), filed by the Company with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). The Shares are to be offered pursuant to the terms of: (i) the Underwriting Agreement, dated as of February 11, 2026 (the “Underwriting Agreement”), by and among the Company and NETSTREIT, L.P., Wells Fargo Bank, National Association and Bank of America, N.A., in their capacities as forward purchasers and forward counterparties, and Wells Fargo Securities, LLC and BofA Securities, Inc., as representatives of the underwriters identified in Schedule I thereto; and (ii) the Forward Sale Agreements (as defined in the Underwriting Agreement).

As counsel for the Company, we have examined the Underwriting Agreement, the Forward Sale Agreements, the Registration Statement, the Prospectus, the Company’s Articles of Amendment and Restatement, as amended through the date hereof (the “Charter”), and the Company’s Amended and Restated Bylaws, as well as originals or copies, certified or otherwise identified to our satisfaction, of such other documents, corporate records, certificates of public officials and other instruments as we have deemed necessary for the purposes of rendering this opinion and we are familiar with the proceedings taken and proposed to be taken by the Company in connection with the authorization, offering and sale of the Shares. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. We have also assumed that the Shares will not be issued in violation of the ownership limit contained in the Charter. This opinion letter is given, and all statements herein are made, in the context of the foregoing.
