Which credit bureau matters most for a mortgage?
Mortgage lenders pull all three bureaus — Equifax, Experian, and TransUnion — and use your middle score, not the highest or lowest. If two borrowers are on the loan, lenders use the lower of the two middle scores.
This is different from the free scores you see on consumer apps, which often use a different model. We pull a true tri-merge mortgage report up front so there are no surprises about which number underwriting will use.
How mortgage credit scoring works
Mortgage lenders pull all three bureaus: Equifax, Experian, and TransUnion. They do not average the scores. They take the middle one.
If two borrowers apply, they use the lower of the two middle scores. That is why one weak file can drag down a couple.
Improving the score that counts
Since the middle score rules, raising your lowest bureau helps most. Check all three reports for errors. A wrong late payment can cost you real money.
We review your tri-merge report with you. Bring questions and we will point out the fastest fixes before you apply.
