Data Analysis

Freddie Mac reported the 30-year fixed-rate mortgage averaged 6.76 percent for the week ending September 10, 2026, up from 6.71 percent a week earlier and 6.35 percent a year ago.

The 15-year fixed-rate average rose to 6.09 percent from 6.04 percent, its second straight week above 6 percent. Both averages sit more than four tenths of a point above where they stood in September 2025.

Freddie Mac reported the 30-year fixed-rate mortgage averaged 6.76 percent for the week ending September 10, 2026, up from 6.71 percent the previous week and up from 6.35 percent a year earlier. The 15-year fixed-rate mortgage averaged 6.09 percent, up from 6.04 percent the previous week and 5.50 percent a year ago. The weekly move is five basis points on both terms. The year-over-year move is the one that changes what a Florida buyer pays: 41 basis points on the 30-year and 59 basis points on the 15-year.

Sam Khater, Freddie Mac's Chief Economist, said in the release that "the 30-year fixed-rate mortgage averaged 6.76% this week" and added that "aspiring buyers should remember shopping around for the best mortgage rate and getting multiple quotes can potentially save them thousands."

What are mortgage rates this week?

Freddie Mac's Primary Mortgage Market Survey puts the 30-year fixed-rate average at 6.76 percent and the 15-year at 6.09 percent for the week ending September 10, 2026. The survey covers conventional, conforming, fully amortizing home purchase loans for borrowers who put 20 percent down and have excellent credit. Rates quoted to an individual borrower with a smaller down payment, a lower credit score, a jumbo balance or an investment property will differ from the survey average, often by a wide margin.

A five basis point weekly change is small enough that it tells a buyer very little. The 30-year average has now moved up in consecutive weeks, from 6.71 percent on September 3 to 6.76 percent on September 10, and both readings sit above the 6.35 percent average Freddie Mac recorded in the same week of September 2025.

The 15-year average crossing 6 percent is the more notable line in this week's survey. It printed 6.04 percent on September 3 and 6.09 percent on September 10. A year ago the same term averaged 5.50 percent. Buyers who use the shorter term to cut lifetime interest cost are now doing so from a starting point roughly six tenths of a point higher than last September.

How much more does a buyer pay at 6.76 percent than a year ago?

Redfin reported a median U.S. home-sale price of $398,637 for the four weeks ending September 6, 2026. A buyer putting 20 percent down on that price borrows about $318,910. At 6.76 percent on a 30-year term, principal and interest on that loan run about $2,071 a month. At the 6.35 percent average Freddie Mac recorded a year ago, the same loan runs about $1,984. The difference is roughly $86 a month, or about $1,034 over a year. These are Momentum Research calculations from the rates and price stated above, and they cover principal and interest only. They exclude property taxes, homeowners insurance, mortgage insurance, flood insurance and any association dues, all of which weigh more heavily in Florida than in most of the country.

The week-over-week change is worth about $11 a month on the same loan. That is inside the noise of what a single lender quote varies by on a given afternoon, which is the practical argument behind Freddie Mac's advice to collect multiple quotes.

Redfin's own measure of the same pressure moved further this week. The company reported that the typical U.S. homebuyer's monthly mortgage payment reached a 14-month high of $2,641 during the four weeks ending September 6, calculated at a 6.71 percent mortgage rate, up 2.8 percent from a year earlier. That figure reflects the rate in effect during the four-week period, not this week's 6.76 percent.

Why did mortgage rates rise this week?

Freddie Mac does not attribute the weekly change to any cause in this release, and neither will we. What can be stated is the data calendar the survey week sat inside.

The Bureau of Labor Statistics reported this morning that the Producer Price Index for final demand rose 0.4 percent in August on a seasonally adjusted basis and 5.4 percent for the 12 months ended in August, up from 4.7 percent for the 12 months ended in July. BLS attributed more than three quarters of the broad-based monthly rise to final demand energy prices, which moved up 4.2 percent, and traced more than a third of the goods increase to diesel fuel, which jumped 24.1 percent. The index for final demand less foods, energy and trade services rose 0.3 percent in August and 4.7 percent over 12 months.

That release landed on the morning Freddie Mac published its survey, so it is not reflected in this week's average. The August Consumer Price Index is scheduled for 8:30 a.m. ET on Friday, September 11, and the Federal Open Market Committee meets September 15 and 16.

What does this mean for Florida buyers?

Rates are a national input into a set of local markets that are not moving together. Redfin's metro data for the four weeks ending September 6 shows West Palm Beach with a 5.9 percent year-over-year increase in pending sales, one of the five largest increases among the 50 most populous U.S. metros. Tampa recorded a 9.7 percent year-over-year increase in new listings and Orlando 8.9 percent, two of the five largest increases in that same group of 50.

No Florida metro appeared on Redfin's lists of the five largest year-over-year increases or decreases in median sale price this period. That means nothing can be inferred about where Florida prices sat relative to the national 2.2 percent year-over-year increase. The absence of a metro from a top-five list is not a data point about that metro.

For a buyer choosing between waiting and moving now, the honest framing is that a 41 basis point year-over-year increase costs about $86 a month on a median-priced purchase, while the week-to-week changes of the past two weeks cost about $11 each. Market-level conditions in a specific Florida metro, including how much inventory has arrived and how much negotiating room sellers are giving, will move a monthly payment more than a five basis point survey change does.

Limitations

Freddie Mac's Primary Mortgage Market Survey is a weekly average of rates offered on conventional, conforming, fully amortizing purchase loans to well-qualified borrowers putting 20 percent down. It is not a rate quote, it is not adjusted for points beyond the survey's own methodology, and it does not describe what any individual Florida borrower will be offered. Freddie Mac publishes a national figure with no state or metro breakout, so nothing in this survey is specific to Florida.

The payment figures in this article are Momentum Research calculations from the stated rates and the stated median sale price. They cover principal and interest only and assume a 20 percent down payment on a 30-year fixed loan. Actual Florida housing payments include property taxes, homeowners insurance, mortgage insurance where applicable, flood insurance where required, and association dues, and those costs vary widely across the state.

The Redfin figures cited here describe four weeks ending September 6, 2026, a period that does not align with Freddie Mac's survey week ending September 10. The median asking price in Redfin's release appears in its data table rather than in the text of the report, and last week's report stated a different asking-price basis, so that series is not used here.

The Producer Price Index figures are national and cover producer-level prices, not consumer prices and not home prices. They are included as calendar context only. No causal link between that release and this week's mortgage rate average is asserted.
