Are you overpaying $147/month on your mortgage?

Choosing a mortgage lender is one of the highest-stakes financial decisions most people make — yet most borrowers accept the first or second offer they receive. On a $400,000 30-year mortgage, a difference of 0.25% in rate is worth approximately $20,000 over the life of the loan. A difference of 0.5% is worth $40,000. Shopping multiple lenders is the single highest-ROI action a homebuyer can take.

APR vs. interest rate — always compare APR. The advertised interest rate does not include origination fees, points, or other closing costs. Annual Percentage Rate (APR) includes all of these and represents the true annual cost of the loan. Two lenders quoting 6.75% may have APRs of 7.1% and 6.9% after fees — a $8,000+ difference on a $400K loan.

The credit score leverage point. Your credit score is the single biggest factor in your offered rate. Borrowers with 760+ scores receive the best available rates. At 720, you may pay 0.25–0.5% more. At 680, the premium can reach 0.75–1.0%. If your score is below 740, it is often worth spending 3–6 months optimizing before applying: pay down revolving debt, dispute errors, and avoid new credit inquiries.

Getting Loan Estimates from multiple lenders. Under RESPA, lenders are required to give you a standardized 3-page Loan Estimate within 3 business days of application. This document makes comparison straightforward — compare Section A (origination charges), Section B (services you cannot shop for), and the APR in the top right corner. Get at least 3 estimates before choosing.

Fixed vs. ARM in the current environment. A 30-year fixed rate provides certainty — your payment never changes. A 5/1 or 7/1 ARM starts lower and adjusts after the initial period. In a high-rate environment where cuts are expected, ARMs are worth considering if you plan to sell or refinance within the initial fixed period. If this is your long-term home, the fixed provides valuable insurance against rate volatility.

Refinancing math. The classic rule: refinancing makes sense when your monthly savings exceed closing costs within 2–3 years. On a $400K loan, closing costs typically run $6,000–$12,000. A $150/month savings recoups $12,000 in 80 months — over 6 years, marginal. A $300/month savings recoups the same in 40 months — clearly worthwhile. Run the math for your specific situation before committing.
