How to Lower Your Mortgage Interest Rate

A lower mortgage rate can make a meaningful difference in your monthly payment, but the lowest advertised rate is not always the least expensive loan. Buyers can compare lenders, pay discount points, negotiate seller credits, explore an assumable mortgage, or consider a temporary buydown. Each option affects the cash needed at closing, the payment over time, or both. I help buyers in San Diego County compare the property and purchase terms while their lender explains the financing options.

1. Ask for a temporary 2-1 buydown

A 2-1 buydown temporarily reduces the rate used to calculate your payments by two percentage points in the first year and one percentage point in the second year. For example, if the loan’s note rate is 6.5%, your first-year payment is calculated at 4.5%, your second-year payment at 5.5%, and the payment returns to the 6.5% note rate in year three. This is an illustration, not a current rate quote. A separate buydown fund covers the difference between the reduced payments and the regular loan payments.

The seller, builder, or another permitted party may fund the buydown, subject to loan program and lender rules. Ask your lender for the cost, the payment in each year, and what happens to unused funds if you refinance or sell early. Make sure the full payment beginning in year three fits your budget; refinancing later is not guaranteed. For Fannie Mae loans, qualification generally uses the applicable rate without the temporary reduction.

2. Buy down the rate permanently with discount points

Discount points are an upfront charge paid at closing in exchange for a lower interest rate. One point equals 1% of the loan amount: on a $600,000 loan, one point costs $6,000. The rate reduction for that payment varies by lender and market; one point does not automatically buy a particular reduction. Ask for a written comparison of the same loan with and without points.

To estimate a simple break-even period, divide the extra cost of the points by the monthly principal-and-interest savings. For example, $6,000 in points divided by $150 in monthly savings is approximately 40 months. That simple calculation does not account for taxes, the time value of money, differences in loan balances, or refinancing costs. Consider how long you expect to keep the loan, not just how long you plan to own the home.

3. Negotiate a seller credit toward your rate

A seller credit can sometimes pay for a temporary buydown or discount points for a permanent rate reduction. Whether a seller will agree depends on the property, competing offers, and the seller’s priorities. The lender must approve the credit and its use; limits vary by loan program, down payment, occupancy, and other circumstances. A higher purchase price offered in exchange for a credit can affect the appraisal, down payment, loan amount, and long-term cost, so compare the entire offer.

For a home that has been on the market for some time, I can discuss whether a seller credit, a price reduction, or a combination makes the most sense. Your lender can prepare side-by-side estimates showing the payment and cash needed at closing for each approach.

4. Consider an assumable mortgage

Some FHA and VA loans may be assumed by a qualified buyer, allowing the buyer to take over the existing loan’s remaining balance, rate, and repayment term, subject to servicer approval. The buyer generally needs cash or approved additional financing to cover the difference between the purchase price and the loan balance, plus closing costs. A VA assumption can also affect the seller’s entitlement, which should be confirmed with the servicer and VA. Explore listed and off-market homes with potentially assumable mortgages.

5. Compare lenders and loan programs

Rates and fees can differ among lenders. Ask several lenders for estimates on the same day using the same loan amount, down payment, loan type, term, and points. Compare the Loan Estimates, including the rate, APR, lender fees, cash to close, and monthly payment. Ask each lender whether the rate is locked, for how long, and whether a float-down option is available and at what cost.

Compare conventional, FHA, VA, and other programs for which you may qualify. A lower interest rate does not necessarily mean a lower total cost: mortgage insurance, funding fees, down payment requirements, and other charges can change the result. Ask about local or state assistance and lender programs as well; eligibility, funding, and terms vary.

6. Improve the factors that affect your offer

A stronger credit profile may help you qualify for a better rate. Review your credit reports for errors, pay bills on time, and ask your lender before opening new accounts or paying off debts during the loan process. A larger down payment may improve pricing and reduce the amount borrowed, although it can leave less cash for reserves and other expenses. Ask the lender to compare actual options before deciding how much to put down.

7. Consider an adjustable-rate mortgage (ARM)

An adjustable-rate mortgage may offer a lower initial rate than a comparable fixed-rate loan. The rate is fixed for an initial period and can then rise or fall according to the loan’s terms. A 5/6 ARM typically has a fixed rate for the first five years, followed by adjustments every six months. A 7/6 ARM typically has a fixed rate for seven years, followed by adjustments every six months. An ARM has a maximum interest rate: the rate cannot go above that limit, no matter how high market rates rise. For example, if your loan starts at 6% and has an 11% maximum, your rate can never exceed 11%. The loan also limits how much the rate can rise at each adjustment. Confirm the exact terms with your lender.

After the initial period, the rate generally depends on a published index plus a margin set in your loan agreement, subject to applicable rate caps. Ask how much the rate can change at the first adjustment, at later adjustments, and over the life of the loan. Request an estimate of the highest possible principal-and-interest payment and compare the ARM’s rate, points, fees, and payment with a fixed-rate loan. An ARM can be worth considering if you understand and can afford the possible adjustments; a future sale or refinance is not guaranteed.

8. Compare a shorter loan term

A 15-year fixed-rate loan may offer a lower interest rate than a comparable 30-year loan, but its required monthly payment is generally higher because the balance is repaid faster. Ask your lender to compare the payments, closing costs, and total interest for each term, and consider whether the higher payment fits your budget.

Which option is best for you?

The right choice depends on your available cash, how long you expect to keep the loan, and whether a lower payment now or long-term savings matters more. Ask your lender to show the note rate, any temporary payment schedule, points or buydown cost, seller credit, total cash to close, and principal-and-interest payment for each option. Include property taxes, insurance, HOA dues, and any mortgage insurance when comparing the full monthly cost.
