James, the most useful thing I can tell you is this: the score your lender pulls is almost certainly not the score on your free credit app, and two mechanical rules you have never been told will decide what rate you are quoted. The ten answers above give you the program minimums, and they are correct. I will not repeat them. Here is what is missing. First, which score. Mortgage underwriting has run for years on the older "Classic FICO" versions, pulled together in a tri-merge report: FICO Score 2 from Experian, FICO Score 5 from Equifax, and FICO Score 4 from TransUnion. Your free app is almost certainly showing you FICO 8 or VantageScore 3.0. Those are different models built at different times, and the gap between what you see and what a lender sees can run into the tens of points in either direction. People find this out at application, which is the worst possible moment. Second, the two rules that set your price. - Lenders use the MIDDLE of your three bureau scores, not the highest and not the average. If you come back 731, 748, and 752, your score is 748. - On a joint application, each borrower's middle score is identified and the lender uses the LOWER of the two. The weaker borrower prices the loan for both of you. That single rule changes more outcomes than anything else on this page, and it is worth running the numbers on whether a co-borrower helps or hurts before you apply. Third, this is genuinely in motion right now, and this question was posted back in early 2024, so the ground has shifted. As of FHFA's April 2026 update, Fannie Mae and Freddie Mac are in an interim phase where an approved lender may deliver a loan using either Classic FICO or VantageScore 4.0. FICO 10T is approved but not yet in use; the Enterprises expected to publish historical FICO 10T scores in the summer of 2026 and to adopt the model later. Credit reporting requirements have not changed yet, and the bi-merge versus tri-merge switch was pushed to a date to be determined. HUD has said it will adopt the new models for FHA loans on its own timeline. Practical translation for you: ask your loan officer which model they are delivering on, because in 2026 two lenders can legitimately score you differently. What I would actually do this month: - Ask a loan officer to pull a tri-merge and show you all three scores. That number is the only one that matters. - Do not close old credit cards. Age of accounts is doing quiet work for you. - Do not open anything new, including a car loan, a store card, or furniture financing, until after you close. - Before you pay down balances, ask your loan officer to run a rapid rescore quote and a what-if simulation. Sometimes paying $400 on one specific card moves you across a pricing tier and thousands of dollars on other cards moves you nothing. I am Zoltan Peresztegi, a real estate professional on the Palos Verdes Peninsula and across the South Bay and greater Los Angeles, so I am not your local agent in Heath. I am glad to connect you with a strong central Ohio agent and a lender from my network who will actually walk you through your tri-merge instead of quoting you a number off an app. Zoltan
