Even a small difference in rate changes your payment and total interest by a lot. Here are the levers that actually move your rate.
Improve your credit score
Rate tiers are largely driven by credit. Paying down balances and fixing errors before you apply can move you into a better tier.
Put more money down
A larger down payment lowers the lender's risk and can improve your rate — and at 20% it removes PMI.
Consider a shorter term
15-year loans almost always carry lower rates than 30-year loans. The monthly payment is higher, but the total interest is far lower.
Buy discount points
Paying points upfront lowers your rate. It makes sense only if you will keep the loan long enough to recoup the cost.
Shop multiple lenders
Rates and fees vary between lenders. Getting several quotes within a short window lets you compare without extra credit-score damage.
