What does the latest mortgage rate snapshot show?

U.S. mortgage rates edged slightly higher in fixed-rate terms as the weekend began on Saturday, Aug. 29, 2026. According to Zillow data, the 30-year fixed mortgage rate rose by 1 basis point to 6.55%, while the 15-year fixed rate increased by 5 basis points to 5.91%. Over the same period, the 5/1 adjustable-rate mortgage fell by 5 basis points to 6.26%.

The figures are based on national averages and are published rounded to the nearest hundredth of a percentage point. Even so, the final cost of a loan can vary depending on the state, ZIP code, loan type, down payment, and the borrower’s credit profile.

What the limited move means for borrowing costs

Although the increase in fixed rates was small, term choice remains important for households calculating monthly payments. A 30-year fixed loan offers a lower monthly payment, while a 15-year term usually comes with a higher payment but a lower total interest burden.

  • 30-year fixed mortgage: lower monthly payment, higher total interest cost
  • 15-year fixed mortgage: higher monthly payment, shorter repayment period
  • 5/1 ARM: fixed rate for the first five years, then annual rate-reset risk

According to the source, mortgage rates are still below where they were a year ago. In addition, rates have fallen by more than half a percentage point since late May, helping drive a more than 62% year-over-year increase in refinancing applications.

Different data sources and the 2026 outlook

Posted rates can vary from one lender or data provider to another. For example, Freddie Mac, the U.S. mortgage finance company, reported a 6.66% rate for the 30-year mortgage this week, while Zillow showed a daily average of 6.55%; the difference mainly comes down to data collection methods and the time period covered.

Forecasts for the rest of the year point to a narrow trading range rather than a sharp drop. The MBA expects the 30-year mortgage rate to stay between 6.6% and 6.7% through 2026, while Fannie Mae sees a year-end range of 6.7% to 6.8%. That outlook makes it even more important for consumers considering a home purchase or refinancing to compare lenders carefully.
