Fannie Mae Initiated PPAs

Fannie Mae’s Data Validation Center (DVC) manages the data validation process. Loans for which Fannie Mae requests a data review are provided to the seller in a DVC Loan Review Report (.xls) in Message Manager. Fannie Mae and the lender will then work together to determine whether a data change is required.
