Uniform Appraisal Dataset (UAD) Appraisal-Level Public Use File (PUF)

Version 2.1 (2/4/2025)

The Uniform Appraisal Dataset (UAD) Appraisal-Level Public Use File (PUF) is the nation’s first publicly available appraisal-level dataset of appraisal records, giving the public new access to a selected set of data fields found in appraisal reports.  The UAD Appraisal-Level PUF are provided separately for the Enterprises (Fannie Mae and Freddie Mac) and Federal Housing Administration (FHA) appraisals:

1. The Enterprise UAD Appraisal-Level PUF is based on a five percent nationally representative random sample of appraisals for single-family mortgages acquired by the Enterprises. The current release includes appraisals from 2013 through 2022.
2. The FHA UAD Appraisal-Level PUF is based on a five percent nationally representative random sample of appraisals for single-family mortgages insured by FHA. The current release includes appraisals from 2017 through 2022.

The UAD Appraisal-Level PUF is a resource for users capable of using statistical software to extract and analyze data. Users can download annual or combined files in CSV, R, SAS and Stata formats. All files are zipped for ease with download.

The UAD Appraisal-Level PUF provides the public and policymakers with meaningful data about appraisals to identify trends, conduct research, and promote compliance. Public, transparent data about appraisals promotes a liquid, efficient, competitive, and resilient national housing market.
