How to Get the Best Mortgage Rate

The single most effective move to lower your mortgage rate is getting quotes from at least three lenders on the same day and letting them compete — that alone routinely beats a single quote by a quarter point or more. Everything else (credit score, down payment, points) sets the band you’ll be offered; shopping decides where in that band you land. The advertised rate you saw is a starting point, not a verdict.

See how even a small rate change moves your payment over 30 years with the Mortgage Calculator, then work the checklist below to earn the lowest one you can.

Credit score: the biggest lever you control

Lenders price risk, and your credit score is their primary read on it. The difference between a 760 and a 660 score can easily be half a percentage point or more — tens of thousands of dollars over the life of the loan.

FICO range	Typical rate tier	Relative cost
760–850	Best available	Baseline
700–759	Slightly higher	+~0.25%
680–699	Noticeably higher	+~0.50%
660–679	Higher still	+~0.75%
Below 660	Subprime / FHA territory	+1%+ or limited options

Before you apply:

• Pull your reports and dispute errors. A single misreported late payment can cost you a tier.
• Pay down revolving balances. Credit utilization below 30% — ideally under 10% — lifts your score, often within one billing cycle.
• Don’t open new accounts or finance a car in the months before applying.
• Keep old cards open. Length of history helps you.

Down payment and loan-to-value

Your loan-to-value ratio (LTV) — the loan amount divided by the home’s value — is the other half of how lenders price risk. More money down means a lower LTV, a lower rate, and at 20% down (80% LTV) you also drop private mortgage insurance entirely.

Lenders set pricing breakpoints at common LTV thresholds. Crossing under 80%, or even from 90% to 85%, can nudge your rate down. Test how much your down payment changes the offer with the Down Payment Calculator. You don’t always need a bigger down payment to win — but if you’re a percentage point away from a better tier, finding that cash can pay off.

Discount points: buying the rate down

A discount point costs 1% of the loan amount and typically lowers your rate by about 0.25%. It’s prepaid interest — you pay up front to save monthly.

Whether points are worth it comes down to your break-even period: how long it takes the monthly savings to repay the up-front cost. Plan to stay past break-even and points win; sell or refinance before it and you’ve lost money. Run your own break-even with the Mortgage Points Calculator. As a rule, points favor people who’ll hold the loan a long time and have cash to spare after the down payment.

Shop multiple lenders — and do it in a window

This is where the real savings hide. Rates and fees vary meaningfully between banks, credit unions, and online lenders for the exact same borrower. Getting three to five quotes is the highest-return hour of work in the entire process.

Two rules make it painless:

• Compare the Loan Estimate, not the headline rate. Every lender must give you a standardized Loan Estimate. Lay them side by side and read the fees — a low rate with fat origination charges can cost more than a slightly higher rate with none.
• Cluster your applications. Credit-scoring models treat all mortgage inquiries within a 45-day window as a single inquiry, so shopping aggressively doesn’t tank your score. Do it inside two weeks to be safe.

APR vs. rate: read both

The interest rate sets your monthly principal-and-interest payment. The APR folds in most lender fees, points, and certain closing costs, expressed as a yearly rate — so it’s a truer measure of the loan’s all-in cost.

A lender advertising a low rate but a much higher APR is loading the loan with fees. Compare offers on APR to catch that, but remember APR assumes you hold the loan to term; if you’ll move in five years, the headline rate and the up-front fees matter more than a 30-year APR. The APR Mortgage Calculator translates a quoted rate plus fees into an APR you can compare apples to apples.

Debt-to-income: clear the bar before you apply

Lenders cap how much of your income can go to debt. Your back-end DTI — all monthly debt payments divided by gross income — generally needs to land at 43% or below, and a lower ratio can earn a better rate, not just an approval.

Paying off a car loan or a credit card before applying can move you into a stronger tier. If your DTI is borderline, that payoff may do more for your rate than anything else on this list. See the related guide on what counts as a good DTI to find your number.

Lock it once it’s right

A rate lock freezes your quoted rate for a set window — commonly 30 to 60 days — protecting you if rates climb before closing. Once you have an offer you’re happy with and a property under contract, lock it. Trying to time the bottom usually costs more than it saves.

Ask about the lock length (it must cover your expected closing date), whether there’s a fee, and whether a float-down option lets you capture a lower rate if the market drops after you lock.

Your rate-lowering checklist

1. Pull your credit reports and dispute any errors.
2. Pay revolving balances below 30% utilization; open no new accounts.
3. Pay down a loan or card to improve DTI if you’re near a threshold.
4. Decide your down payment — aim under a pricing breakpoint, ideally 20%.
5. Get Loan Estimates from 3–5 lenders within a two-week window.
6. Compare them on APR and fees, not the headline rate.
7. Run a points break-even; buy points only if you’ll hold past it.
8. Lock the rate once the offer and timeline are right.

The borrower who does all eight doesn’t just qualify — they qualify at the best rate available to their profile, and on a 30-year loan that’s real money. Start by pricing your scenario in the Mortgage Calculator.
