Uniform Appraisal Dataset
Fannie Mae and Freddie Mac (the GSEs) have worked on the UAD redesign since 2018, leveraging extensive stakeholder input to update the appraisal dataset, align it with current mortgage industry data standards (MISMO® v3.6), and replace the GSE appraisal forms with a single data-driven, flexible, and dynamic appraisal report for any residential property type. To begin the multiyear rollout phase, the GSEs have published the technical specifications and resources below.
Uniform Appraisal Dataset Redesign Additional Documentation
The Uniform Appraisal Dataset (UAD) and Forms Redesign team has released additional documentation to support ongoing implementation efforts. This resource supplements the initial documentation released in March 2023, which kicked off industry development and preparation for the new appraisal dataset and report.
- The UAD Compliance Rules for the Uniform Residential Appraisal Report (URAR) will help lenders and vendors deliver the XML in compliance with the UAD Delivery Specification. These rules verify data completeness, validity (format and data type), and reasonableness.
