How to Lower Your Mortgage Interest Rate

A lower rate can reduce your payment, but upfront fees and loan terms matter too. Compare these eight options based on your available cash, monthly budget, and how long you expect to keep the loan.

I help San Diego buyers evaluate homes and negotiate purchase terms, working with their lender to compare financing options.

Start with your target monthly payment, available down payment, and moving timeline. We’ll use those priorities to focus your home search and the questions to discuss with your lender.

1. Temporary 2-1 Buydown

A 2-1 buydown lowers your payments for the first two years. A separate fund covers the difference; your loan’s interest rate stays the same.

Example with a 6.5% loan:
Year 1: payments calculated at 4.5%
Year 2: payments calculated at 5.5%
Year 3 onward: regular payments at 6.5%

A seller, builder, or other permitted party may fund the buydown. Ask your lender about the cost, qualification requirements, and unused funds if you sell or refinance early. Make sure you can afford the full payment in year three. These rates are illustrative.

2. Discount Points

Discount points are an upfront cost in exchange for a lower interest rate. One point equals 1% of your loan amount—$6,000 on a $600,000 loan. The rate reduction varies, so compare written offers with and without points.

Simple break-even example: $6,000 in points ÷ $150 in monthly savings = 40 months. Consider how long you expect to keep the loan. This rough calculation excludes taxes, changes in loan balances, and the time value of money.

3. Seller Credits

A seller credit may help pay for a temporary buydown or discount points. I can negotiate a credit, a price reduction, or a combination and coordinate with your lender to compare the payment and cash needed at closing.

Credit limits depend on the loan program and your circumstances. If you offer a higher price in exchange for a credit, compare the effect on the appraisal, down payment, and total borrowing cost.

4. Assumable Mortgages

Some FHA and VA loans allow a qualified buyer to take over the owner’s remaining mortgage balance, rate, and term. You need cash or approved additional financing to cover the gap between the purchase price and loan balance, plus closing costs.

Confirm approval requirements with the servicer. For a VA loan, also check the effect on the seller’s entitlement. Explore homes with potentially assumable mortgages.

5. Compare Lenders and Programs

Ask several lenders for Loan Estimates on the same day, using the same loan amount, down payment, term, and points. Compare the rate, APR, fees, cash to close, and monthly payment. Check how long each rate lock lasts.

Compare programs you qualify for, including conventional, FHA, and VA loans. Mortgage insurance, funding fees, and down payment requirements can change which offer costs less. Ask about available assistance programs, too.

6. Credit and Down Payment

Review your credit reports for errors and pay bills on time. Ask your lender before opening new accounts or paying off debts during the loan process.

A larger down payment may improve loan pricing, but it also leaves less cash for repairs and reserves. Have your lender compare the options before deciding how much to put down.

7. Adjustable-Rate Mortgages

An ARM may offer a lower starting rate than a fixed-rate loan. A 5/6 ARM is typically fixed for five years, then adjusts every six months; a 7/6 ARM is fixed for seven years before those adjustments begin.

Your loan sets limits on rate increases. If it starts at 6% and has an 11% lifetime maximum, the rate cannot exceed 11%. Separate caps limit the first and later adjustments. Confirm the exact limits in your loan terms.

After the fixed period, the rate generally follows an index plus the lender’s margin, subject to those caps. Ask for the highest possible principal-and-interest payment. Choose a loan you can afford without relying on a future sale or refinance.

8. Shorter Loan Terms

A 15-year loan may offer a lower rate and less total interest than a 30-year loan, but usually requires a higher monthly payment. Compare both payments and closing costs, and decide whether the faster payoff fits your budget.

Which Option Fits Your Budget?

Ask your lender for a side-by-side comparison of upfront costs, monthly payments, and long-term savings. Include property taxes, insurance, HOA dues, and any mortgage insurance in your monthly budget.

I can help you evaluate homes, negotiate purchase terms, and coordinate with your lender as you compare your options.
