Fannie Mae’s Uniform Appraisal Dataset (UAD) and Forms Redesign team released additional documentation and updated one existing document to support ongoing implementation efforts, according to news released in Fannie Mae’s Single-Family newsletter.

These resources supplement the initial documentation released in March 2023 kicking off industry development and preparation for the new appraisal data set and report, along with subsequent documents published in 2023 and 2024.

New information includes:

• Functioning without Form Numbers: Mapping Legacy Forms to Redesigned Uniform Residential Appraisal Report (URAR) Property Type Characteristics – Helps the transition to the new report by providing clarification on how existing appraisal form numbers map to the URAR’s new dynamic structure and discrete and repeatable data.
• Lender Readiness Kit – Supplement to the previously published Partner Playbook. It helps lenders prepare for and adopt the updated UAD and retire the existing appraisal forms. It offers timelines and roadmaps to keep lenders on track and additional resources to learn more along the way.
• UAD Compliance Rules for the Restricted Appraisal Update Report and Completion Report (Appendix H-2, Appendix H-3) – Helps lenders and vendors deliver the XML in compliance with respective delivery specifications. These rules verify data completeness, validity (format and data type), and reasonableness. Where applicable, the UAD team kept the messaging and rule logic consistent with the UAD Compliance Rules - URAR previously published in September 2023.

  Updated information includes:

• Updated: UAD Compliance Rules for the Uniform Residential Appraisal Report (URAR) (Appendix H-1) – Aligns with the UAD Delivery Specification and provides further clarification of rule logic and/or message text. Updates are identified in the Revision History section of the document.
