With 30-year fixed rates still hovering near 6 percent, a 0.25-point difference in APR saves about $17,000 in interest on a $350 k loan over 30 years. Add closing-cost variation, and the “cheapest headline rate” is often not the cheapest loan.

Key Take-aways

  1. Credit unions dominate headline APRs thanks to member-owned, lower-margin models.
  2. Non-banks advertise aggressively (Rocket, loanDepot) but recoup margin via higher fees.
  3. Big banks reward loyalty: relationship credits can shave 0.125–0.250 pts—worth factoring into your calculator.

How to Choose the Right Offer

Factor Why It Matters Quick Rule-of-Thumb
APR vs Closing Costs A 0.10 pt lower APR ≈ $7/mo on $350 k. If fees exceed 0.25 pt of loan, higher APR may be cheaper short-term. Use our mortgage calculator; set loan term to 5 years if you expect to move.
Rate-Lock Policy Extending beyond 45 days can add 0.125 pt. Negotiate a free 15-day extension if builder delays.
Pre-payment Penalty Rare on conforming loans, common on portfolio jumbos. Avoid any penalty > 1 % of principal.
Points Strategy Buying 1 pt today costs ~2 % of loan; breakeven ≈ 6 yrs. Buy points only if staying > 7 yrs.

The true cheapest mortgage in 2025 blends rate, fees, and perks. Credit unions like Navy Federal top the list for APR, while fintechs like Better.com win on low fees. Big-bank relationship discounts can tilt the decision if you already keep assets there.
