What is Fannie Mae's value acceptance + property data?

Fannie Mae's value acceptance + property data is an update to the seller guide released March 2023. This change will use data and technology to accept lender-provided value. This will allow lenders to deliver loans that meet certain criteria to Fannie Mae without an appraisal. The process involves using 3rd party companies to collect property data and submit it to FNMA via API.
