UAD and Forms Redesign Updated Documentation

As part of our ongoing commitment to supporting a smooth transition to the Uniform Appraisal Dataset (UAD) 3.6 and Forms Redesign, Freddie Mac and Fannie Mae (the GSEs) have made minor updates to existing documentation on their websites. These changes, which were identified during the Limited Production Period, aim to improve the accuracy and usability of our documentation.

Updates include edits to the UAD 3.6 Compliance Rules, which will be available in production on May 14, 2026. For a detailed overview of all changes, please refer to the revision history within each document.
