B4-1.1-06, Uniform Appraisal Dataset (UAD) and the Uniform Collateral Data Portal (UCDP) (06/04/2025)

The UAD standardizes appraisal data elements for a subset of fields on specific appraisal report forms and includes all data elements required to complete these forms. Fannie Mae requires that the following appraisal report forms are completed utilizing Appendix D of the UAD Specification when reporting the results of an appraisal for a conventional loan:

• Uniform Residential Appraisal Report ( Form 1004),
• Uniform Residential Appraisal Report (Desktop) (Form 1004 Desktop)
• Uniform Residential Appraisal Report (Hybrid) (Form 1004 Hybrid)
• Individual Condominium Unit Appraisal Report ( Form 1073), and
• Individual Condominium Unit Appraisal Report (Hybrid) (Form 1073 Hybrid).

Other appraisal report forms may be completed using the standards contained in the UAD Specification to the extent those standards are applicable to that particular form. Lenders may obtain the most recent version of Appendix D of the Uniform Appraisal Dataset Specification and additional information on Fannie Mae’s website. 

The UCDP is a portal through which lenders are required to electronically submit appraisal reports for conventional loans sold to Fannie Mae. The following appraisal report forms including all exhibits, addenda, and photographs, must be submitted through the UCDP and receive a “Successful” status from the UCDP prior to sale of the loan to Fannie Mae:

• Uniform Residential Appraisal Report ( Form 1004),
• Uniform Residential Appraisal Report (Desktop) (Form 1004 Desktop),
• Uniform Residential Appraisal Report (Hybrid) (Form 1004 Hybrid)
• Manufactured Home Appraisal Report ( Form 1004C),
• Small Residential Income Property Appraisal Report (Form 1025),
• Individual Condominium Unit Appraisal Report ( Form 1073),
• Individual Condominium Unit Appraisal Report (Hybrid) ( Form 1073 Hybrid), and
• Individual Cooperative Interest Appraisal Report ( Form 2090).

If there are subsequent revisions to the appraisal report, the final version of the report that was utilized in making the underwriting decision must be submitted through the UCDP and receive a “Successful” status from the UCDP prior to sale of the loan to Fannie Mae. When submitting an appraisal report through the UCDP, lenders must ensure it is the unaltered report submitted by the identified appraiser.

Additionally, for loans that require an appraisal, lenders must ensure the appraised value as indicated on the appraisal submitted to UCDP matches the appraised value as reported at sale of the loan. An exception is allowed for this requirement when the appraisal used to underwrite the loan is a desk or field review of an existing appraisal because those types of reports cannot be submitted through the UCDP. In those instances, the appraised value reported at sale of the loan will reflect the value as stated in the desk or field review. However, the original appraisal that was the subject of review must have been submitted to UCDP.

Appraisal report forms not listed above cannot be delivered through UCDP with the exception of the Appraisal Update and/or Completion Certificate ( Form 1004D ), which is optional. Lenders must maintain the applicable appraisal report and attachments in the loan file as part of the underwriting documents in accordance with A2-4.1-02, Ownership and Retention of Loan Files and RecordsA2-4.1-02, Ownership and Retention of Loan Files and Records. Lenders may obtain detailed information on the UCDP page on Fannie Mae’s website.

Lenders using UAD 3.6 must follow the requirements in the UAD 3.6 Policy Supplement .
