It decides whether you're approved — and the rate you pay for the next 30 years. The gap between "fair" and "good" credit can be hundreds of dollars a month. Here's how to see what it's costing you, and how to fix it fast.
Same house, same down payment — just a different credit score. Watch the monthly payment move. (Estimates based on typical credit-tier pricing; your real numbers depend on lender, program, and the day's rates.)
Drag your current score and a target score to see the difference in real dollars.
Estimates for education only — not credit, financial, or mortgage advice, and not a credit-repair service. Credit scoring models are proprietary; rate and PMI pricing by score band are approximate and vary by lender and loan program. Point-change estimates are directional, not guarantees.

The score in your free app usually isn't the one a mortgage lender sees — and the gap can cost you a whole tier.
Credit Karma and most free apps show a VantageScore. Mortgage lenders pull older, specific FICO versions from all three bureaus — FICO 2 (Experian), FICO 4 (TransUnion), FICO 5 (Equifax) — and those are often 20–60 points lower. They use the middle of your three scores; for a couple, the lower partner's middle. Knowing these before you shop is the difference between confidence and a nasty surprise at application.
As of April 2026, Fannie & Freddie began accepting VantageScore 4.0, with FICO 10T phasing in later this year. But Classic FICO 2/4/5 is still what most lenders use right now, and a tri-merge from all three bureaus is still required — so the mortgage FICOs above are the numbers that matter today.
The one consumer source for the actual mortgage-version FICOs (2 / 4 / 5) across all three bureaus is myFICO. Grab yours — especially before a coaching call — so you're working from the numbers a lender actually sees.

Lenders don't price every single point — they price bands. That means a borrower at 718 and a borrower at 700 often pay the same… but jump from 718 to 720 and your pricing can improve overnight. A few points across the right line can be worth thousands.
If you're sitting just below a tier line — 619, 639, 659, 679, 699, 719, 739 — you don't need a huge overhaul. You might need 5–10 points in the right place. That's the difference between "I need a year" and "I need a few weeks," and it's exactly where the fast moves below pay off.
The fastest score gains before a mortgage almost always come from one lever — utilization — plus not shooting yourself in the foot. Here's the playbook.
This is the stuff I learned at the closing table, not from a blog — and credit was the part I dealt with more than rates or fees. Used carefully, in the right order, these are how I took people from "denied" to "approved" in days. Education only, and every credit file is different — but here's what I saw work, over and over.
Counterintuitive, but real: don't zero out all your cards, and don't close them. Pay each card down to exactly a $25 balance — no matter the limit. A tiny reported balance scores better than all-zeros (which can read as "no active use"), while keeping your utilization right on the floor. Then let it report and watch it climb.
When you're close to a tier, your lender can order a rapid rescore: verified paydowns and corrections pushed to the bureaus in 2–5 days instead of waiting a full billing cycle. I've watched scores come back 120+ points higher that fast. It's the most underused tool in the business — ask your loan officer about it by name.
If a collection is older than about 24 months, the scoring model has largely stopped counting it. Pay it off and you can re-trigger that collection as if it were brand new — and your score drops. Crazy, but that's exactly how it works. Leave sleeping collections alone unless you have a deletion agreement in writing (see #4).
Instead of just paying a collection, negotiate to have it deleted in exchange for payment — in writing, before a dollar changes hands. It works especially well on medical collections, and the jumps can be enormous. I took a client from a 590 to a 723 in five days doing exactly this. Always get the delete agreement in writing first.
Credit-repair shops love to dispute everything, because a tradeline marked "in dispute" gets temporarily ignored — so your score looks higher. But mortgage underwriting engines (DU and LPA) catch it and literally instruct: "remove the dispute, rescore, and resubmit." Once it's removed, the real, lower score comes back — and if a loan officer misses that dispute flag, the deal can die at the closing table. Don't dispute accurate items before or during a mortgage.
Five things, weighted roughly like this. Spend your energy where the points are.
