Mortgage Denied:
Credit Score — Agency or Overlay?

By Ziya Y. · 23 Years Banking · FinanceRateCalc Decision Intelligence System

A credit score denial is the most common — and most misunderstood — mortgage rejection. Before you spend months rebuilding credit, determine whether you were denied by an agency minimum or a lender overlay.

Agency minimums (the actual rules):
FHA: 580 minimum (3.5% down) · Conventional: 620 minimum · VA: No set minimum

Was It an Overlay?

If your credit score is above the agency minimum but below what the lender required, your denial was an overlay. Examples:

If It Was an Agency Rule

Scores below 580 mean even FHA is off the table short-term. Focus: 30-60 days of credit repair can often add 20-40 points. Pay down credit card utilization below 30%, dispute any errors, and avoid new credit applications.

The half of the answer almost nobody publishes free

Credit-score thresholds are the visible half of qualifying. The other half is which lender receives your file — and that half is measurable. In the complete 2025 federal HMDA record (1,187,606 FHA applications that reached a credit decision), denial rates across the 100 largest FHA lenders ranged from 1.8% to 78.7%. Same federal program, same year: a 44× spread.

And it is not simply a matter of who applies where. Holding state, loan amount, income, debt-to-income and loan-to-value constant across 24,933 borrower-profile cells, applicant mix explains only a 2.9× range — while the observed spread stays 44×.
