To facilitate electronic delivery of appraisal report data to the government-sponsored enterprises (GSEs), Fannie Mae and Freddie Mac developed the Uniform Collateral Data Portal^® (UCDP^®) as part of the Uniform Mortgage Data Program^® (UMDP^®).

If an appraisal report is required, lenders must use UCDP to submit electronic appraisal data files that conform to all GSE requirements – and when applicable, the Uniform Appraisal Dataset (UAD) – before the mortgage is delivered to Fannie Mae or Freddie Mac.
