Mortgage Scores vs Consumer Scores
The score in your credit-monitoring app is not the score your lender pulls. The gap is usually 20–40 points.
Consumer apps like Credit Karma show VantageScore 3.0. Mortgage lenders pull FICO 2, 4, and 5 from Experian, TransUnion, and Equifax - three separate scores. Underwriting uses the middle of the three. For two applicants, they use the lower middle. These 'mortgage FICOs' weight installment history, credit age, and utilization differently than the newer VantageScore, and typically come in lower.
Don't panic when your mortgage-pulled score is lower than what you see in an app. Budget rate quotes around the mortgage FICO, not the consumer score.
