Uniform Appraisal Dataset
The Uniform Appraisal Dataset (UAD) is a component of the Uniform Mortgage Data Program® (UMDP®), jointly established by Fannie Mae and Freddie Mac under the direction of their regulator, the Federal Housing Finance Agency (FHFA), to provide common requirements for appraisal and loan delivery data.
Uniform Collateral Data Portal
The Uniform Collateral Data Portal® (UCDP®) is a single portal through which lenders electronically submit reports for conventional mortgages delivered to Fannie Mae or Freddie Mac. Through the UCDP, lenders can upload appraisal data and view edits and submission details.
The Uniform Standards of Professional Appraisal Practice (USPAP) are the generally accepted standards for professional appraisal practice in North America. USPAP contains standards for all types of appraisal services, including real estate, personal property, business, and mass appraisal. For more details, click here.
The Appraisal Foundation has also released a one-page matrix paper that shows which portions of USPAP apply to particular assignments. To view the Appraisal Foundation's matrix in its entirety, click here.
