Tri-merge report
A mortgage credit report that combines your Equifax, Experian and TransUnion files and scores into one document for the lender.
Mortgage lenders pull all three bureaus at once, which is why one preapproval usually shows an inquiry at each. FHFA says tri-merge remains required for loans sold to Fannie Mae and Freddie Mac, and a plan to allow two-bureau reports was postponed. HUD's Mortgagee Letter 2026-11 says FHA will continue to require a tri-merge report even as it adds new score models.
Because the lender sees all three files, an error or collection on a single report can still matter, especially if it pulls that bureau's score into the middle position. Lenders using VantageScore 4.0 for Fannie Mae loans must request it from all three bureaus. Check all three reports months before applying, rather than only the one your app shows.
