What we checked to reach this conclusion
We cross-referenced the Federal Housing Finance Agency's published loan-level price adjustment (LLPA) matrices — the actual fee schedules that lenders use when pricing conventional loans — against Fannie Mae and Freddie Mac underwriting guidelines, FICO's own research on score composition, and rate data from the Consumer Financial Protection Bureau's mortgage market monitoring reports. Where lender marketing language conflicted with what the fee schedules actually show, we went with the fee schedules. The numbers below are not estimates — they come from the same documents your loan officer looks at.
-
FHFA Loan-Level Price Adjustment (LLPA) matrices reviewed Confirmed that the pricing advantage of a 760+ score over a 700–719 score on a 30-year conventional loan with 20% down translates to a rate difference of approximately 0.5–0.75 percentage points as of early 2026, depending on loan size.
-
Fannie Mae and Freddie Mac selling guides consulted Confirmed the 620 minimum score floor for conventional purchase loans and the score tiers at which LLPAs are applied or waived.
-
FICO score factor research reviewed Confirmed that payment history (35%) and amounts owed / utilization (30%) are the two dominant levers in a FICO score, and that reducing utilization can produce score changes within a single billing cycle — faster than any other factor.
-
CFPB mortgage market data reviewed Confirmed the real-world rate dispersion between score tiers using the CFPB's Consumer Expenditure and mortgage origination data, which tracks actual offered rates by credit score band across thousands of originations.
Your score sits somewhere on a spectrum — here's what each tier actually means
Your situation determines which path makes the most sense: if you're close to 760, a short delay and targeted credit moves often saves far more than any rate negotiation. If you're well below 620, government-backed loan programs exist that conventional wisdom undervalues.
What people commonly try that doesn't actually help
Several well-marketed credit-improvement tactics are either ineffective for mortgage purposes, actively counterproductive, or slower than advertised — and acting on them before you apply can cost you time, money, or both.
-
Opening new credit cards to "increase available credit" — While this can lower your aggregate utilization ratio over time, each new account triggers a hard inquiry (which temporarily lowers your score), reduces your average account age (another scoring factor), and lenders reviewing your mortgage application will flag recent new accounts as a risk signal — some will require a written explanation and may even re-pull your credit the day before closing.
-
Paying off installment loans (car loans, student loans) to improve your score before applying — Counterintuitively, paying off an installment loan in full can slightly lower your FICO score in the short term by reducing your credit mix and lowering the number of active accounts. The effect is usually small but is the opposite of what most people expect, and the cash used could have been more effectively deployed to reduce revolving utilization.
-
Credit repair companies that promise rapid score increases — Legitimate credit repair companies can only do what you can do yourself for free: dispute inaccurate information. They cannot legally remove accurate negative information, no matter what their marketing implies. The FTC has taken repeated enforcement action against companies making such claims. Save the monthly fee and spend an afternoon disputing errors directly with the bureaus at AnnualCreditReport.com.
-
Closing old credit card accounts to "clean up" your credit profile — Closing accounts reduces your total available credit (raising utilization) and can shorten your average account age — both of which lower your score. Unless a card carries an annual fee you can't justify, keep old accounts open and at zero or very low balances in the months before you apply.

I was sitting at 718 when I first looked at buying. I paid off two credit cards completely — brought my utilization from about 38% down to 6% — and waited two billing cycles. Score jumped to 771. My loan officer said the difference on my rate was 0.625% which on a $385,000 loan worked out to around $1,400 a year. Absolutely worth the wait.

Found a medical collection on my Equifax report from a 2019 ER visit that had already been paid. Filed a dispute online with documentation, and Equifax removed it in 18 days. Score went from 694 to 739. Still not at 760 but the rate I got was noticeably better than the pre-approval I'd gotten three months earlier. The dispute process was genuinely easy — maybe 45 minutes of my time total.

I tried the utilization trick but my score only went up about 18 points, not the 40–50 I'd hoped for. Turns out my credit history is pretty short — only about 4 years — and that was holding me back more than I realized. I ended up going FHA at 688 rather than waiting another year. The MIP is annoying but I plan to refinance once I hit 20% equity. Wish I'd understood the age-of-accounts factor sooner.
