Frequently Asked Questions
How much can a better credit score save on a mortgage? ▾
The difference between excellent (760+) and poor (620-639) credit on a $350,000 30-year mortgage can be $150,000-$200,000 in total interest — a difference of $300-500 per month in payments. Even moving from Good (680) to Very Good (740) credit can save $20,000-$40,000 over the life of a mortgage. Few financial improvements pay as well as building excellent credit.
Do lenders use the same credit score? ▾
No. There are many FICO versions (FICO 8, FICO 9, FICO 10) and VantageScore versions (3.0, 4.0). Mortgage lenders typically use older FICO versions (FICO 2, 4, or 5) and may pull all three bureaus (Equifax, Experian, TransUnion). Auto lenders often use FICO Auto Score 8. Credit cards typically use FICO 8 or VantageScore 3.0. The free scores from Credit Karma use VantageScore 3.0, which is directionally accurate but may differ from lender scores by 20-40 points.
What credit score do I need for the best mortgage rate? ▾
Most lenders require 620 minimum to qualify for a conventional mortgage. FHA loans allow scores as low as 580 (with 3.5% down) or 500 (with 10% down). To get the best rates, you generally need 740+. Rates typically improve at 620, 660, 680, 700, 720, 740, and 760 — these are common score tiers lenders use for pricing. If you're within 20-30 points of a tier, it may be worth delaying a purchase to improve your score first.
