Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to CaliberCos Inc., a Delaware corporation (the “Company”), in connection with the Registration Statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), on or about the date hereof, relating to the proposed offer, issuance and sale, from time to time on a delayed or continuous basis pursuant to applicable provisions of Rule 415 under the Securities Act, as set forth in the Registration Statement, any amendment thereto, the prospectus contained therein (the “Shelf Prospectus”), any supplements to the Prospectus (each, a “Prospectus Supplement”), and any related free-writing prospectus(es) relating to the proposed issuance and sale, from time to time, by the Company of up to a maximum of $50,000,000 in aggregate offering proceeds of a presently indeterminate amount of the following securities of the Company (each a “Security” and collectively, the “Securities”):
shares of Class A common stock, par value $0.001 (“Common Stock”);
shares of preferred stock, par value $0.001 per share, in one or more series or classes (the “Preferred Stock”);
debt securities, in one or more series, which may be either senior debt securities, or subordinated debt securities (the “Debt Securities”) to be issued pursuant to an indenture and any supplemental indenture (collectively, an “Indenture”) between the Company and a trustee or bank to be named (the “Trustee”);
warrants to purchase Common Stock, Preferred Stock, Debt Securities or any combination of these securities (the “Warrants”), which may be issued under warrant agreements (each, a “Warrant Agreement”), to be dated on or about the date of the first issuance of the applicable Warrants thereunder, by and between the Company and a warrant agent to be selected by the Company (the “Warrant Agent”);
rights to purchase Debt Securities, Common Stock, or Preferred Stock (the “Rights”), which may be issued independent or together with any other security offered hereby and may not be transferable by the stockholder receiving such rights under a rights agreements (each, a “Rights Agreement”), by and between the Company and the rights agent to be selected by the Company (the “Rights Agent”); and
units consisting of two or more Debt Securities, Common Stock, Preferred Stock, or Warrants described above in any combination(s) thereof (each a “Unit” and collectively the “Units”).

We are delivering this opinion pursuant to the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act. No opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement, the Shelf Prospectus or any Prospectus Supplement, other than as expressly stated herein with respect to the Securities.

In connection with this opinion, we have examined (i) the Registration Statement, including the exhibits filed therewith, (ii) the Shelf Prospectus, (iii) the Company’s Third Amended and Restated Certificate of Incorporation, as amended or supplemented (the “Certificate of Incorporation”), (iv) the Company’s Amended and Restated Bylaws, as amended (the “Bylaws”), and (v) the corporate resolutions and other actions of the Company that authorize and provide for the issuance of the Securities. We have also examined and relied upon originals, or copies certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other



instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. As to certain factual matters, we have relied upon a certificate of an officer of the Company and have not independently sought to verify such matters. In our capacity as your counsel in connection with the Registration Statement, we have been advised of the proceedings taken and proposed to be taken by you in connection with the authorization of the Indenture, Rights Agreement, Warrant Agreements, and the issuance and sale of the Securities. For the purposes of this opinion, we have assumed that such proceedings to be taken in the future will be completed timely in the manner presently proposed and that the terms of each issuance of Securities will otherwise be in compliance with New York law or Delaware General Corporation Law, as applicable.

In such examination and in rendering the opinions expressed below, we have assumed, without independent investigation or verification: (i) the genuineness of all signatures on all agreements, instruments, corporate records, certificates and other documents submitted to us, (ii) the legal capacity and authority of all persons or entities (other than the Company) executing all agreements, instruments, corporate records, certificates and other documents submitted to us, (iii) the authenticity and completeness of all agreements, instruments, corporate records, certificates and other documents submitted to us as originals, (iv) that all agreements, instruments, corporate records, certificates and other documents submitted to us as certified, electronic, facsimile, conformed, photostatic or other copies conform to authentic originals thereof, and that such originals are authentic and complete, (v) the due authorization, execution and delivery of all agreements, instruments, certificates and other documents by all parties thereto (other than the Company), (vi) that the statements contained in the certificates and comparable documents of public officials, officers and representatives of the Company and other persons on which we have relied for the purposes of this opinion set forth below are true and correct, and (vii) that the officers and directors of the Company have properly exercised their fiduciary duties. We have also assumed (1) that the Registration Statement and any required post-effective amendment thereto have all become effective under the Securities Act and such effectiveness shall not have been terminated, suspended or rescinded; (2) that the Shelf Prospectus and any and all Prospectus Supplement(s) required by applicable laws and any and all free-writing prospectus(es) related to the offer and sale of the Securities have been delivered and filed as required by such laws; (3) that the issuance and sale of the Securities will be in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement, (4) the due authorization, execution and delivery (other than by the Company) of all documents where authorization, execution and delivery are prerequisites to the effectiveness of such documents; and (5) that the issuance and sale of the Securities by the Company and any Indenture, Warrant Agreement, Rights Agreement, or unit agreement relating to Units will not, in each case, violate or result in a default under or breach (a) the Certificate of Incorporation or the Bylaws, (b) any agreement or instrument binding upon the Company, (c) any law, rule or regulation to which the Company is subject, (d) any applicable requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, or (e) any consent, approval, license, authorization or validation of, or filing, recording or registration with any governmental authority.

With respect to our opinion as to the Common Stock, we have assumed that, at the time of issuance and sale, a sufficient number of shares of Common Stock are authorized and available for issuance and that the consideration for the issuance and sale of the Common Stock (or for Preferred Stock or Debt Securities convertible into Common Stock, or for Warrants exercisable for Common Stock, or for Rights exercisable for Common Stock, or Units including Common Stock) is in an amount that is not less than the par value of the Common Stock. With respect to our opinion as to the Preferred Stock, we have assumed that, at the time of issuance and sale, a sufficient number of shares of Preferred Stock are authorized, designated and available for issuance and that the consideration for the issuance and sale of the Preferred Stock (or for Debt Securities convertible into Preferred Stock, or for Warrants exercisable for Preferred Stock, or Rights exercisable for Preferred Stock or Units including Preferred Stock) is in an amount that is not less than the par value of the Preferred Stock. We have also assumed that any Debt Securities or Warrants offered under the Registration Statement and the related Indenture and Warrant Agreement, will be executed substantially in the form filed as an exhibit to the Registration Statement or incorporated by reference therein and that, in the case of Debt Securities, the Trustee shall have been qualified pursuant to the Trust Indenture Act of 1939, as amended, at the time the Debt Securities are offered or issued (or such later time as may be permitted pursuant to the rules, regulations, interpretations or positions of the Commission).

Our opinion herein is expressed solely with respect to the Delaware General Corporation Law and, as to the Debt Securities and Warrants constituting valid and legally binding obligations of the Company, solely with respect to the laws of the State of New York. We express no opinion herein as to any other laws, statutes, ordinances, rules, or regulations (and in particular, we express no opinion as to any effect that such other laws, statutes, ordinances,



rules, or regulations may have on the opinions expressed herein). We are not rendering any opinion as to compliance with any federal or state antifraud law, rule or regulation relating to securities, or to the sale or issuance thereof.

The opinions set forth below are subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought; (iii) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of, or contribution to, a party with respect to a liability where such indemnification or contribution is contrary to public policy; (iv) we express no opinion concerning the enforceability of any waiver of rights or defenses with respect to stay, extension or usury laws; and (v) we express no opinion with respect to whether acceleration of any Debt Securities may affect the ability to collect any portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon. We express no opinion as to any provision of the Debt Securities that: (a) relates to the subject matter jurisdiction of any federal court of the United States of America or any federal appellate court to adjudicate any controversy related to the Debt Securities or (b) contains a waiver of an inconvenient forum. We express no opinion as to whether the laws of any jurisdiction are applicable to the subject matter hereof.

On the basis of the foregoing and in reliance thereon, and subject to the qualifications herein stated, we are of the opinion that:
