The Federal Housing Finance Agency (FHFA) published a final rule in August that presents the standards, criteria and process that Fannie Mae and Freddie Mac (Enterprises) will use to validate and approve third-party credit score models.
The final rule is effective Oct. 15, 2019, but FHFA anticipates the process of approving an alternative credit score model will take up to 26 months, a timeframe that doesn’t include implementation of any approved model.
FHFA has stated that, based on years of related credit score work, it will take the industry approximately 18-24 months to adopt a new credit score model after a model has been approved.
Fannie Mae and Freddie Mac currently require lenders to provide credit scores derived from the Classic FICO credit score model for each loan delivered to Fannie or Freddie and said it expects the Classic FICO to meet the criteria for approval based on its history of use.
If Fannie or Freddie conditions its purchase of a mortgage loan on the provision of a borrower’s credit score, the score must be produced by a model that has been validated and approved through the following process:
For a credit score model to be approved for use, the model must pass both a credit score assessment and an Enterprise business assessment. FHFA then reviews a proposed determination by an Enterprise for use of the credit score model and will either approve or disapprove the proposed determination. If an application is approved by FHFA, the Enterprise must follow through with a final determination to approve the credit score model for use in its systems.
