Strategies That Actually Move Your Mortgage Rate
Lenders price mortgage rates based on a handful of factors you can influence: credit score, loan-to-value ratio, loan term, and whether you pay discount points. Understanding which levers matter most — and by how much — lets you negotiate from a position of knowledge.
Credit Score: The Biggest Lever
A credit score below 680 can cost you 0.5%–1.5% in rate compared to a 740+ borrower on the same loan. That's $94–$281/month extra on a $300,000 loan. If your score is between 680 and 740, it may be worth waiting 3–6 months to pay down credit card balances and remove any errors before applying. See our guide on refinancing with a lower credit score if you're starting below 640.
Loan-to-Value: Below 80% Matters
Lenders price better rates for borrowers with 20%+ equity (LTV below 80%). Below that threshold, you're either paying PMI or accepting a slightly higher rate. If you're close to 20% equity, making extra principal payments to cross that line before applying can save you more than the extra payments cost.
Discount Points: Worth It or Not?
Buying points to reduce your rate makes sense if you'll stay long enough to recoup the upfront cost. On a $300,000 loan, one point = $3,000 upfront and saves roughly $53/month, meaning your break-even is about 57 months (~4.75 years). Use the break-even calculator to model points alongside closing costs.
Lock Timing and Lender Competition
Getting 3–5 quotes within a 14-day window is treated as a single credit inquiry by FICO, so shopping doesn't hurt your score. The Federal Reserve's Consumer Finance Protection Bureau found that borrowers who got just one additional quote saved an average of $1,500. Getting five quotes saved an average of $3,000. Always compare Loan Estimates — not just the quoted rate.
