30-Year Mortgage Rate Dips to 6.65% Amid Housing Market Shifts

The average interest rate for a 30-year fixed mortgage has decreased to 6.65% for the week ending August 20, marking a 2 basis point reduction from the previous week's 6.67%, according to Freddie Mac. This represents the second consecutive weekly decline in mortgage rates, offering a slight reprieve to prospective homebuyers. However, current borrowing costs remain elevated compared to the year-ago period, when the average rate stood at 6.58%.

For a homebuyer considering a median-priced U.S. home valued at $430,000, a 20% down payment would amount to $86,000, leaving a loan principal of $344,000. At the current 6.65% interest rate, the monthly payment for principal and interest is approximately $2,208. This figure is $5 lower than the previous week's payment of $2,213. When compared to the rate of 6.58% observed in August 2025, which would have resulted in a monthly principal and interest payment of $2,192 for the same home price, today's buyers are facing an additional $16 per month.

For individuals utilizing FHA loans, which typically require a 3.5% down payment, the monthly costs have also seen a marginal increase. On a $430,000 home, a 3.5% down payment equates to approximately $15,050, resulting in a financed amount of roughly $414,950. With the current 6.65% rate, the monthly principal and interest payment for this loan scenario is approximately $2,664. This is a $5 reduction from the prior week's payment of $2,669. However, when contrasted with the 6.58% rates from August 2025, where the monthly payment for a similar loan amount was $2,645, FHA borrowers are now paying an extra $19 per month in interest. Despite these increases, current rates offer significant relief compared to the peak of 7.79% experienced in October 2023, which would have led to a monthly payment of $2,984 for a home at this price, representing a saving of $320 per month today.
