Fixed-rate mortgage rates fell sharply this week while adjustable-rate mortgage (ARM) rates remained unchanged. The 30-year fixed rate dropped to approximately 6.45%, down from 6.72% last week, while the 15-year fixed fell to around 5.65% from 5.89%. Common ARM products held steady near 5.95% for 5/1 ARMs and 5.75% for 7/1 ARMs, as of October 20, 2026. These moves create meaningful opportunities for both home buyers and existing homeowners considering a refinance.

Today’s Rates by Loan Type

According to data tracked by Freddie Mac and reported through the Federal Reserve’s H.15 release, the following rates are available to well-qualified borrowers (those with credit scores above 740, loan-to-value ratios under 80%, and strong debt-to-income ratios):

30-year fixed-rate mortgage: 6.45% (down 27 basis points from last week)

15-year fixed-rate mortgage: 5.65% (down 24 basis points from last week)

5/1 adjustable-rate mortgage: 5.95% (unchanged from last week)

7/1 adjustable-rate mortgage: 5.75% (unchanged from last week)

FHA 30-year fixed: 6.20% (down approximately 25 basis points)

VA 30-year fixed: 6.15% (down approximately 28 basis points)

Rates vary by lender, location, loan amount, down payment, and individual borrower qualifications. These figures represent national averages for borrowers who pay approximately 0.7 discount points at closing.

What This Week’s Movement Means

The sharp decline in fixed rates reflects recent Federal Reserve policy signals and softer-than-expected inflation data released earlier this month. As covered in foundational texts such as Principles of Finance, mortgage rates typically track movements in the 10-year Treasury yield, which fell nearly 18 basis points over the past week on expectations of slower economic growth.

The stability in ARM rates is notable. Adjustable-rate products price off shorter-term indices, and the market currently expects the Federal Reserve to hold short-term rates steady through the end of the year. This divergence between fixed and ARM pricing narrows the traditional rate advantage ARMs offer, currently just 50 basis points for a 5/1 ARM versus the 30-year fixed.

Buyer and Refinance Implications

For home buyers, this week’s fixed-rate drop translates to real savings. On a $400,000 loan, the 27-basis-point decline in the 30-year rate reduces the monthly principal and interest payment by approximately $65, or $780 annually. Over the life of the loan, that represents more than $23,000 in total interest savings.

For refinancing borrowers, the break-even calculation becomes more favorable. If you currently hold a 30-year mortgage above 7%, this week’s rates may justify a rate-and-term refinance, depending on your remaining loan term and typical closing costs in your area (usually 2% to 3% of the loan amount). Run a break-even analysis to determine how many months it takes to recover closing costs through lower monthly payments.

ARM borrowers or those considering ARMs should note that the fixed-ARM spread has narrowed significantly. Unless you plan to sell or refinance within the initial fixed period, the modest rate advantage may not justify the adjustment risk when rates reset.

Next Steps

Verify current rates directly with at least three licensed lenders in your area. Mortgage rates change daily based on market conditions, and lender pricing varies. Request loan estimates that show the interest rate, APR, discount points, and estimated closing costs for accurate comparisons.

If you are considering a refinance, calculate your break-even point by dividing total closing costs by your monthly payment savings. Refinancing typically makes sense when you will remain in the home long enough to recover those costs.
