Even a 0.25% difference in your mortgage rate changes your total interest paid by tens of thousands of dollars over a 30-year term. When evaluating lenders, consider these factors alongside the headline rate:
- APR vs. interest rate — the APR includes origination fees and gives a more accurate total-cost comparison across lenders
- Points — paying discount points upfront lowers your rate but extends the break-even period; worthwhile only if you stay in the home long enough
- Fixed vs. adjustable — ARMs start lower but carry rate-reset risk after the initial period; fixed rates offer long-term payment certainty
- Lender type — banks, credit unions, and online lenders each offer different rate structures, underwriting timelines, and service models
- Rate lock period — confirm how long the quoted rate is guaranteed during the underwriting process before you are committed
