The 30-Year Is 6.76%. That Is the Third Weekly Rise, Not a Blip.
Freddie Mac’s survey for the week ending September 10 put the 30-year fixed at 6.76% and the 15-year at 6.09%. Here is the four-week path and what it does to a Florida purchase or listing.
Freddie Mac’s Primary Mortgage Market Survey for the week ending September 10, 2026 put the 30-year fixed at 6.76%. The 15-year fixed was 6.09%. Both were five basis points above the prior week.
That is the third weekly rise in a row. FRED’s MORTGAGE30US series — the same Freddie Mac survey — printed 6.65% on August 20, 6.66% on August 27, 6.71% on September 3, and 6.76% on September 10. Eleven basis points in three weeks. NAR’s August existing-home report used a 6.67% August monthly average. The weekly tape has already left that month behind.
This is a national rate story, not a Nature Coast closed-sale count. It sits next to Friday’s August CPI print and the MBA applications survey. A 6.76% survey average does not invent a Tampa Bay list price. It can change who clears the payment on a house you already liked. For local process, keep the Florida home buying guide and the Pasco, Hillsborough, and Pinellas overviews in the same reading list.
The official four-week path
Freddie Mac PMMS, 30-year fixed, weeks ending:
- August 20: 6.65%
- August 27: 6.66%
- September 3: 6.71%
- September 10: 6.76%
The 15-year fixed was 6.09% for the week ending September 10, also up five basis points from 6.04% the week before. The next PMMS print is due September 17.
Two other rate series will show up in the same conversation. MBA’s weekly applications survey for the week ending September 4 put its contract 30-year at 6.85%. Daily lock indexes move inside the week. Neither replaces Freddie Mac’s Thursday survey. If a headline says 6.76% and your lender says 6.9%, both can be honest. They are different clocks.
What 11 basis points actually change
The survey is an average of lender applications, not your lock. Still, the direction is the payment. A buyer who budgeted off late-August 6.66% is now shopping a higher payment before taxes and insurance. Florida insurance is a separate line. Do not let a national rate chart hide the HO-3.
For illustration only — not a quote — principal and interest on a $400,000 loan amortizing 30 years is about $57 a month higher at 6.76% than at 6.66%. That is the whole three-week move on a round number. It is enough to knock a thin first-time-buyer file out of a price band. It is not enough to reprice a street.
Refis are the other casualty. MBA said refinance applications in the week ending September 4 fell to the slowest weekly pace since May 2025. A 6.76% purchase rate is not a refinance market for anyone who closed in 2020–2021.
What it does to housing
For a buyer, treat the lock as dated merchandise. A pre-approval from July is a credit story, not a payment story. Ask for a written quote after September 10. If you are a thin-file first-time buyer, the VantageScore 4.0 rent-score guide is the credit half of the file. This print is the rate half.
For a seller, three rising weeks are why Saturday traffic thins before the listing is “wrong.” August existing-home sales were 3.98 million, down 2.0% from July, with 1.62 million homes on the market and a 4.9-month supply. Price against that tape, not against last spring. The pricing strategy guide is the process.
For a new-construction shopper, builders still have more months of supply than resale. Census’s July new-home print was 9.6 months. Rate buydowns are a builder tool, not a Freddie Mac gift. Ask what the payment is after the buydown expires.
Neighborhood files do not change because the Thursday survey ticked: Wesley Chapel, New Tampa, Dunedin, Clearwater.
What it does to commercial real estate
Almost nothing one-for-one. A 30-year residential survey is not a cap rate. The second-order link is household formation and the cost of take-out financing on residential-adjacent product: garden-style, build-to-rent, and small mixed-use. Keep commercial files in the Pasco commercial overview and the Hillsborough commercial overview. Do not paste 6.76% onto a U.S. 19 asking cap.
The through-line
The 30-year is 6.76% because the weekly survey rose for a third straight Thursday, not because a slogan changed. Friday’s CPI did not invent that path. It can keep it from reversing before the September 15–16 FOMC. If you are buying or listing in Hernando, Citrus, Pasco, Hillsborough, or Pinellas this week, use a current quote and a current comp. Do not use last month’s 6.67% August average as if it were still on the lock desk.

Questions people ask first
Quick answers to common questions about this topic.
What is the current Freddie Mac 30-year mortgage rate?
For the week ending September 10, 2026, Freddie Mac’s Primary Mortgage Market Survey put the 30-year fixed at 6.76% and the 15-year fixed at 6.09%. Your lender’s lock can differ.
Is this the third week in a row that rates rose?
Yes on the Freddie Mac 30-year series. The weekly prints were 6.65% on August 20, 6.66% on August 27, 6.71% on September 3, and 6.76% on September 10.
Why does my lender quote a different rate than 6.76%?
Freddie Mac averages lender applications for a week. MBA’s survey and daily lock indexes use different samples and timing. MBA’s contract 30-year was 6.85% for the week ending September 4.
Does a higher survey rate mean I should wait to buy?
Waiting is a bet that the next print is lower. The FOMC meets September 15–16. A current written quote and a house that clears today’s payment is a plan. A hope that 6.50% returns is not.
Will this lower Florida home prices this week?
No. It can thin the buyer pool. August existing-home sales were already 3.98 million with a 4.9-month supply. Local insurance and inventory still set the listing.
