Uniform Appraisal Dataset

Improving the quality and consistency of appraisal data

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.
