What Determines Your Mortgage Rate

Mortgage rates are driven by two categories of factors: macroeconomic factors you don't control (the 10-year Treasury yield, Fed policy, inflation expectations) and individual borrower factors you can influence. Your rate = market rate + lender margin + risk adjustments based on your profile. Understanding the risk adjustments tells you exactly where to focus improvement efforts.

Key borrower-controlled factors and their typical rate impact: credit score (biggest impact, up to 1.5% range), loan-to-value ratio (10% vs. 20% down: ~0.1%–0.3% difference), debt-to-income ratio (high DTI can add ~0.1%–0.25%), loan type (VA/USDA vs. conventional), loan size (conforming vs. jumbo), property type (condo adds ~0.25%–0.75% vs. single family), and occupancy (investment property adds ~0.5%–1.5% vs. primary).

Strategy 1: Improve Your Credit Score

The most impactful move you can make. FICO scores from 680 to 760 can reduce your rate by 0.5%–1.0%. On a $400,000 mortgage, that's $40,000–$80,000 in interest savings. Primary score drivers: payment history (35%), credit utilization (30%), credit age (15%), credit mix (10%), new inquiries (10%).

The fastest improvement: pay down revolving credit card balances to below 30% utilization (ideally below 10%). This single action can raise scores 30–50+ points for people with high utilization. Do this 3–6 months before applying. Also: dispute any errors on your credit report, avoid opening new accounts in the 6 months before applying, and don't close old accounts (reduces average account age).

Strategy 2: Reduce Your DTI

Pay off any small balances (car loans, personal loans, credit card balances) before applying. Every recurring monthly payment eliminated improves your front-end and back-end DTI, which allows you to qualify for lower rates and better terms. A $300/month car payment paid off before applying can increase your maximum loan qualification by $75,000 at a 4.8% back-end DTI.

Strategy 3: Shop 3–5 Lenders

This is the simplest, highest-ROI move. Mortgage rates vary 0.25%–0.75% between lenders for the exact same borrower — lenders have different risk appetites, cost structures, and capacity. CFPB data shows borrowers who get 5 quotes save an average of $3,000 over those who get 1 quote. Getting quotes costs nothing. Apply within a 45-day window — FICO scoring models treat all mortgage inquiries within this window as a single inquiry for scoring purposes.

Where to compare: direct banks, credit unions (often offer lower rates and fees), online lenders (LoanDepot, Better Mortgage, Rocket), and mortgage brokers (shop many lenders at once). Always get a Loan Estimate (standardized federal form) — it allows apples-to-apples comparison of rate, APR, and closing costs.

Strategy 4: Increase Your Down Payment

More equity at origination reduces lender risk and results in lower rates. Moving from 5% to 20% down typically reduces the rate by 0.1%–0.3% in addition to eliminating PMI. The rate improvement is most pronounced at the key LTV thresholds: above 80% LTV (below 20% down), above 75% LTV, and above 60% LTV. If you're close to a threshold, it may be worth a few more months of saving.

Strategy 5: Consider a 15-Year Mortgage

15-year mortgages carry rates 0.5%–0.75% lower than 30-year mortgages. If you can afford the higher payment, the shorter term saves dramatically in two ways: lower rate and fewer years of interest. The 15 vs. 30-Year Calculator shows the full savings comparison for your specific numbers.

Strategy 6: Analyze Mortgage Points

Mortgage discount points let you "buy down" the rate: 1 point = 1% of the loan amount, typically reduces the rate by 0.125%–0.25%. The break-even calculation: point cost ÷ monthly savings = months to break even. A $3,800 point (1% of $380K) that saves $76/month breaks even in 50 months (4.2 years). If you'll keep the mortgage at least 5 years, buying a point saves money. Shorter timeline: skip the points.

Strategy 7: Get Pre-Approved During Rate Lock Shopping

Once under contract, rates can move. Lock your rate once you're within 45–60 days of closing and rates look favorable. Float-down options (typically cost 0.1%–0.25%) let you capture a lower rate if rates fall after locking. Know your closing date before deciding on lock length — if closing might extend, a shorter lock may be cheaper (shorter locks have lower rates) but you'll need to extend or relock if it delays.

Strategy 8: Use VA or USDA Loans if Eligible

VA loans (for veterans and active military) typically offer rates 0.25%–0.5% below comparable conventional loans — and with no down payment and no PMI. USDA loans (for eligible rural/suburban properties) also offer below-market rates with no down payment. If you qualify for either program, they almost always beat conventional loans on total cost. Check VA eligibility at VA.gov and USDA eligibility at eligibility.sc.egov.usda.gov.
