FICO vs. VantageScore: Which Credit Score Matters Most for Mortgages in 2025?

Introduction: Why Credit Scores Matter More Than Ever in 2025

Buying a home in 2025 is tougher than ever. With rising interest rates, higher home prices, and tighter lending standards, your credit score plays a crucial role in mortgage approval and the rate you’ll pay.

But here’s the shocking part: The credit score you see on free apps like Credit Karma probably isn’t the score your mortgage lender sees.

In fact, lenders use a specific version of your score — usually an old FICO model — not the newer VantageScore most apps show.

Let’s clear up the confusion between FICO vs. VantageScore and show you exactly which score matters most for your mortgage.

What is a FICO Score?

Developed in 1989 by Fair Isaac Corporation, the FICO score remains the gold standard in lending.

FICO Models Used for Mortgages:

• FICO Score 2 — Used by Experian
• FICO Score 4 — Used by TransUnion
• FICO Score 5 — Used by Equifax

These are old models — but mortgage lenders like Fannie Mae and Freddie Mac still rely on them.

Newer models like FICO 8, FICO 9, or FICO 10 are used for credit cards, auto loans, and personal loans — but rarely for mortgages.

What is a VantageScore?

The VantageScore was created in 2006 by Experian, Equifax, and TransUnion as an alternative to FICO.

VantageScore Versions:

• VantageScore 3.0 — Most commonly shown on free apps
• VantageScore 4.0 — Introduces trended data (spending patterns over time)

Side-by-Side Comparison: FICO vs. VantageScore

Key Differences:

• VantageScore is more forgiving of recent credit activity.
• FICO weighs hard inquiries and credit age more heavily.
• VantageScore uses trended data — analyzing your financial habits over time.
• FICO focuses more on payment history and utilization.

What Score Range is Considered Good for Mortgages?

What Credit Score Do Mortgage Lenders Really Use in 2025?

Most mortgage lenders — especially those using Fannie Mae, Freddie Mac, VA loans, FHA loans — will pull your FICO score from:

• Experian (FICO 2)
• Equifax (FICO 5)
• TransUnion (FICO 4)

Why Your Credit Karma Score is Usually Wrong for Mortgages

Credit Karma uses VantageScore 3.0, not FICO.

Real-Life Example:

• Credit Karma Score: 710 (VantageScore)
• Mortgage Lender FICO 2 Score: 660

This difference could mean thousands more in interest or even a loan denial.

Experian vs. TransUnion vs. Equifax: Do Scores Differ?

Yes — because:

• Not all lenders report to all bureaus.
• Each bureau may have different data.
• Different FICO versions calculate scores slightly differently.
