The average 30-year fixed purchase mortgage rate is 6.54% on Monday, August 17, 2026, according to rates from the Zillow lender marketplace. That is 5 basis points lower than the 30-year refinance rate of 6.59%. Mortgage rates today are slightly lower for home buyers than for people refinancing their loans.
Because the borrower has to repay the same debt in half the time, the downside is that the monthly payment is much higher. For example, on a $300,000 mortgage at 6.04% for 15 years, the monthly principal-and-interest payment would be about $2,537.41, according to Yahoo Finance. However, the total interest paid over the life of that loan would be about $156,734, which is much lower than the interest cost in the 30-year example.
ARMs can sometimes start with lower rates than fixed mortgages. But there is a risk: the rate can rise after the initial fixed period ends, which can increase the monthly payment. In that case, the borrower could benefit from the lower starting rate without staying long enough to face later rate increases.
An ARM may make sense for someone who expects to sell the home before the initial rate period ends.
Lenders generally offer better rates to borrowers with higher down payments, excellent credit scores and lower debt-to-income ratios, according to Yahoo Finance. A borrower’s financial profile can affect the mortgage rate they receive. If you want a lower mortgage rate, you can consider saving for a larger down payment, improving your credit score or paying down existing debt before applying for a home loan. But a lower rate does not always mean a better deal. Borrowers need to compare the upfront cost of the buydown with the amount they will actually save each month. One important question is how long you plan to stay in the home. If you move or refinance before recovering the cost of the buydown, the extra money paid upfront may not be worth it.
