What these rates are
These figures come from the Optimal Blue Mortgage Market Indices (OBMMI). Each business day the index averages the interest rates on loans locked through Optimal Blue, which covers more than a third of U.S. mortgage transactions. They are interest rates, not APR.
How they are shown
Every rate on this page is the 5-day average of the daily index. That keeps all loan types on the same date and smooths out the day-to-day swings that show up in smaller categories such as jumbo and USDA. Data is as of Oct 13, 2026. The source publishes with a delay of about two business days, and this page checks for updates several times a day.
Averages are not quotes
For illustration purposes only. Rates shown are national averages, not a rate quote, offer or commitment to lend, and are not specific to any lender, state or borrower. Your actual rate and terms depend on your credit profile, loan amount, down payment, property type and lender approval, and may differ from the rates shown.
A second measure: Freddie Mac
Freddie Mac publishes a separate weekly survey based on loan applications. It tends to land near the daily index but not on it, because it covers a different set of loans over a different period.
| Survey | Latest | Week of | Previous week | Year ago |
|---|
| Freddie Mac 30-year fixed | 7.40% | Oct 8, 2026 | 7.28% | 6.30% |
|---|
| Freddie Mac 15-year fixed | 6.73% | Oct 8, 2026 | 6.60% | 5.53% |
