Uniform Appraisal Dataset Redesign Additional Documentation

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.

Uniform Appraisal Dataset Redesign Begins Rollout Phase

The Uniform Appraisal Dataset (UAD) and Forms Redesign has taken a big step by announcing the release of the implementation resources. Freddie Mac and Fannie Mae (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, 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 posted an industry playbook, technical specifications, and sample appraisal reports.

UAD Overview

As part of the Uniform Mortgage Data Program® (UMDP®), Freddie Mac and Fannie Mae have worked together at the direction of the Federal Housing Finance Agency to develop the Uniform Appraisal Dataset (UAD) and the Uniform Collateral Data Portal® (UCDP®) in an effort to enhance appraisal data quality and consistency and promote the collection of electronic appraisal data.
