Data Analysis

Freddie Mac put the 30-year fixed mortgage rate at 6.66 percent in the week ending August 27, 2026, one basis point above last week and 10 above a year ago.

The 15-year fixed averaged 5.98 percent, up from 5.95 percent a week earlier. Rates have climbed 0.68 point since bottoming at 5.98 percent in late February.

Freddie Mac reported the 30-year fixed mortgage rate at 6.66 percent for the week ending August 27, 2026, up from 6.65 percent a week earlier and 6.56 percent a year ago. The 15-year fixed averaged 5.98 percent, up from 5.95 percent last week and 5.69 percent a year earlier. "Mortgage rates changed little this week averaging 6.66 percent," Freddie Mac said in its Primary Mortgage Market Survey. The 30-year rate is now 0.68 percentage point above its 2026 low of 5.98 percent, set in the week ending February 26.

The week-to-week move is one basis point, which is nothing. The shape of the year is the story.

What are mortgage rates right now?

The Primary Mortgage Market Survey put the 30-year fixed at 6.66 percent and the 15-year fixed at 5.98 percent for the week ending August 27, 2026. Both are higher than a week ago and higher than a year ago. The 30-year is up 0.10 point over twelve months and the 15-year is up 0.29 point.

The 30-year rate fell through the back half of 2025 and reached 5.98 percent in the week ending February 26, 2026, the lowest weekly average in the survey since 2022. It has risen through most of the spring and summer since, touching 6.69 percent in the week ending August 6 before easing to the current level. The last three weekly prints, 6.69, 6.67 and 6.65, followed by this week's 6.66, describe a rate that has stopped falling and is holding near the top of its recent range.

How much has the payment changed?

Take a $400,000 purchase with 20 percent down, which leaves a $320,000 loan. At this week's 6.66 percent, principal and interest on a 30-year fixed run about $2,056 a month.

At the 6.56 percent rate of a year ago, the same loan ran about $2,035, so the twelve-month change costs roughly $21 a month, or about $254 a year. That is small.

Against February, it is not small. At 5.98 percent the same loan ran about $1,914 a month. A buyer who was shopping in late February and is still shopping now is looking at roughly $142 more a month on identical terms, about $1,703 a year, with no change in the price of the house.

The 15-year at 5.98 percent works out to about $2,697 a month on the same $320,000, which is $641 more than the 30-year and retires the loan in half the time.

These are principal and interest only. Florida buyers should add property taxes and insurance, and in much of the state insurance is the line item that decides affordability rather than the rate.

What does this mean for Florida buyers and sellers?

Put this week's rate next to what prices did. The Federal Housing Finance Agency reported Tuesday that Florida house prices rose 0.96 percent over the year through the second quarter, against 2.1 percent nationally, with Jacksonville and the Miami-Miami Beach-Kendall division slightly negative.

So Florida prices are close to flat and financing costs are modestly higher than a year ago. For a buyer, the year of waiting did not buy much. Prices did not fall enough to matter in most of the state, and the rate went the wrong way by a tenth of a point. For a seller, the buyer pool is working with slightly less purchasing power than it had last August, which shows up as longer negotiations and more concession requests rather than as a visible drop in list prices.

The February window is the more useful reference. Buyers who locked then are carrying payments that today's shoppers cannot get, which is one reason existing owners are slow to list and trade up.

Local conditions vary widely across the state. Current figures by market sit on the Tampa, Orlando, Jacksonville and Miami hub pages.

Why does the survey rate differ from quoted rates?

The Primary Mortgage Market Survey reports average commitment rates on conventional, conforming, first-lien purchase mortgages with 20 percent down and strong borrower credit. It is a weekly average across lenders, not a quote.

A specific borrower's rate moves with credit score, down payment, loan size, property type, occupancy and the day they lock. Condominium financing, investment property and loans above the conforming limit all price differently, and all three are common in Florida. Points paid at closing also move the number, and the survey's rates come with an average of a small fraction of a point.

Treat the survey as the trend line the market is priced off, not as the rate any one buyer will be offered.

Limitations

The survey covers conventional conforming purchase loans only. It excludes FHA and VA lending, jumbo loans above the conforming limit, refinances, and cash purchases, and cash is a substantial share of Florida transactions.

Weekly averages are volatile and small week-to-week moves like this week's one basis point carry no signal on their own. Freddie Mac collects the survey from lenders across the country and does not publish a Florida-specific rate, so the figures here describe national financing conditions applied to Florida prices, not a measured Florida rate.

The payment illustrations above are principal and interest on a hypothetical loan at the survey average. They exclude taxes, insurance, HOA and mortgage insurance, and they are not a quote.
