Mortgage Navigator • Conventional

Conventional loans—without pretending Fannie Mae and Freddie Mac are always the same.

Most conventional rules can be explained once. When Fannie Mae and Freddie Mac differ in a way that can change eligibility, documentation, AUS results or approval, Mortgage Navigator calls it out.

Important 2026 credit change: for agency AUS-approved conventional loans, there is no longer a blanket agency minimum credit-score floor. Fannie Mae's DU does not require a minimum credit score for DU loan casefiles, and Freddie Mac does not require a minimum Indicator Score for LPA Accept mortgages. Approval is driven by the AUS risk assessment—not an old universal “620 minimum” rule.
Don't overgeneralize: manually underwritten loans still have agency-specific minimum-score requirements, and certain products, mortgage insurance, lender overlays or other eligibility rules may still use credit-score thresholds.

How this library works

When the agencies are materially aligned, we explain the conventional rule once. When they differ, you'll see an Agency Difference section showing Fannie, Freddie and why the difference matters to the borrower.
