Credit score and your mortgage rate

Your credit score is not one number

You actually have dozens of credit scores. Each bureau (Equifax, Experian, TransUnion) keeps its own data, and on top of that data several different scoring models can be run. The most common consumer-facing number is a VantageScore 3.0 (used by Credit Karma and most banking apps). Lenders almost never use that for mortgages. The score in Finanzo's own credit monitoring is also a VantageScore 3.0, provided for educational purposes — it is not the Classic FICO tri-merge score a mortgage lender will pull.

For mortgages, the industry standard is the older FICO mortgage models:

• Equifax: FICO 5
• Experian: FICO 2
• TransUnion: FICO 4

These models are 10–15 years older than what your phone app shows you. They weight some things more heavily (medical collections, for example) and may give you a meaningfully different score — sometimes 20–30 points lower, sometimes higher — than the score in your favorite app.

How credit scores affect your mortgage

Two things change with your credit score: whether you qualify and what rate you pay. The approval thresholds:

• 500–579: FHA only, with 10% down. No Conventional.
• 580–619: FHA with 3.5% down possible. Conventional may be tight.
• 620–679: All major loan types open. Pricing adjustments still meaningfully impact rate.
• 680–739: Decent rates, getting better at each 20-point band.
• 740–759: "A-tier" pricing on most products.
• 760+: Best pricing on Conventional. Going higher than 760 doesn't save you much more.

How big is the rate difference? On a Conventional 30-year fixed for $400,000, going from a 660 score to a 760 score can change the rate by 0.75–1.50%. On a 30-year loan that's tens of thousands of dollars in lifetime interest. It's the single highest-leverage thing most buyers can change before applying.

What FICO actually weighs

FICO has published its weighting since the 1990s. Here’s the breakdown of what makes up your score:

• Payment history (35%)

  On-time vs late payments. A single 30-day late on a credit card can drop your score 60–110 points. The damage fades over time, but late payments stay on your report for 7 years.

• Amounts owed / utilization (30%)

  How much of your available revolving credit you’re using. Lower is better. Under 10% utilization is ideal for the score.

• Length of credit history (15%)

  How old your accounts are on average. Closing your oldest credit card in your 30s can hurt your score for years to come.

• New credit / inquiries (10%)

  Hard inquiries (when you apply for new credit) ding your score by a few points and stay on your report for 2 years. Soft inquiries (your own checking, prequalifications) don’t count.

• Credit mix (10%)

  Having a mix of credit types (revolving + installment) helps slightly. Don’t go open new accounts just for this.

The fastest ways to bump your score

If you have 90 days before applying for a mortgage, here are the things that move the needle quickest:

1. Pay down credit cards below 30% utilization, ideally below 10%. This is the single fastest lever — utilization updates monthly when your statement closes. A card balance of $4,000 on a $5,000 limit (80% util) is hammering your score; pay it to $400 (8% util) and it can jump 30–80 points in one cycle.
2. Don’t close old credit cards. Keep them open even at $0 balance — they preserve length of history and your total credit limit (which lowers utilization across all your cards).
3. Don’t open new accounts during the mortgage process. New accounts ding your score, lower your average account age, and add to your DTI all at once. If a furniture store offers 0%-financing-for-12-months while you're under contract — politely decline.
4. Become an authorized user on a relative’s old, well-managed card. If your parent has a 20-year-old Amex with perfect payment history, adding you as an authorized user can boost your length-of-history. They don’t even need to give you the physical card.
5. Dispute errors. About 1 in 5 credit reports has a material error. Pull your reports for free at AnnualCreditReport.com (the official site, not the ones with similar names) and dispute anything wrong with the bureau directly.
6. Pay off collections — but with a "pay for delete" agreement when possible. A paid collection is still a collection on older FICO models. Some collectors will agree in writing to remove the account from your credit report in exchange for payment. Always get the agreement in writing before paying.

Rapid rescore: paying for a faster update

Lenders have access to a process called a rapid rescore that can update your credit report and pull a fresh score within 3–7 days, instead of waiting for the next monthly cycle. It costs $30–60 per item per bureau and your loan officer initiates it. This is helpful if you paid down a card and need the new score to lock a better rate before lenders pull again.

You can’t request a rapid rescore yourself — it has to come through your lender. And it only updates information that was actually paid or disputed; you can’t use it to "manufacture" a higher score.
