Supporting quality control using DU validation service

Guidance and resources to assist with pre-funding and post-closing activities

We all know that loan quality matters. The process of assessing quality through your pre-funding and post-closing quality control (QC) is both a Fannie Mae Selling Guide requirement and a key component of your own risk management.

Fannie Mae considers striving for loan quality to be a shared commitment between lenders and Fannie Mae.

Here you’ll find information about QC requirements, process relief, and other responsibilities when leveraging the DU validation service.

Note: Fannie Mae expects vendors on our platform to provide high-quality data. As part of our ongoing vendor monitoring, we encourage lenders to report any data discrepancies they see in any third-party verification reports to Day 1 Certainty Data Discrepancy mailbox.

 

Lender QC Requirements

In all cases, the lender is responsible for reviewing the whole file (including for any contradictory information) and for re-verifying any components of the loan that were not validated by DU, in accordance with the Selling Guide.

Also, the lender is responsible for complying with any other prefunding and post-closing QC requirements in the Selling Guide.
