The number landed on Thursday: 7.03 percent. That is the average 30-year fixed mortgage rate for the week ending September 24, according to Freddie Mac’s weekly survey, up from 6.95 percent the week before and the first time the benchmark has crossed 7 percent since January 2025. For anyone shopping for a home this fall, the math just got harsher.
And the official number may already be stale. Freddie Mac’s survey is a weekly average, so it lags fast-moving markets. Mortgage News Daily, which tracks rates daily, put the average 30-year fixed at 7.45 percent on Thursday, up from 7.26 percent a day earlier. Bankrate’s survey came in at 7.17 percent. However you measure it, borrowing costs are at their highest in well over a year, and NPR noted this is the first time above 7 percent in 20 months. The 15-year fixed jumped too, to 6.42 percent from 6.26 percent, Freddie Mac reported.
The culprit is the bond market. The 10-year Treasury yield, the benchmark mortgage rates actually follow, hovered around 5 percent this week and touched 5.225 percent on Thursday, its highest since 2007. Inflation expectations are running high, fed by rising energy prices tied to the war with Iran and other conflicts constraining global oil supply. Jeff DerGurahian, LoanDepot’s chief investment officer, told USA Today that oil prices and inflation are the market’s “primary focus.” The Fed’s rate hike last week, its first since 2023, added to the pressure, though as NPR explained, the 30-year mortgage follows the 10-year Treasury’s trajectory, not the Fed’s overnight rate.
Freddie Mac’s chief economist, Sam Khater, struck a calmer note in the release: “The housing market remains supported by a solid labor market and an economy that is growing at a healthy rate.” The data backed him up, at least for new homes. Sales of new single-family houses surged 6.4 percent in August to a seasonally adjusted annual rate of 684,000, the highest since December 2025 and well above the 615,000 economists expected, the Census Bureau reported via Reuters.
But look closer and the strength has an asterisk. Builders are buying those sales with discounts. The median new-home price fell 5.8 percent from a year earlier to $393,700, and 38 percent of builders reported cutting prices in September, with two-thirds offering sales incentives, the most since December, according to the National Association of Home Builders via Inman. Builder sentiment fell to 32, its 17th straight month below the break-even mark of 50. HousingWire put it plainly: August’s sales pace looks less like an inflection point than evidence of builders absorbing the cost of making monthly payments work for buyers. With 483,000 new homes for sale, an 8.5-month supply, the discounting has room to continue.
The resale market tells the other half of the story. The median existing single-family home price was $434,800 in August, up 1.7 percent from a year earlier, according to the National Association of Realtors via Inman, sitting above the new-home median for a change. Existing owners, many locked into sub-4 percent mortgages from years past, have little reason to sell into this market. New homes, where builders can cut prices and buy down rates, are where the action is. Two markets, two realities.
Borrowers are adapting. Adjustable-rate mortgages, which run more than a percentage point cheaper than fixed loans, made up 9.8 percent of applications in the latest Mortgage Bankers Association survey, well above the roughly 6 percent norm, while refinance activity sat 62 percent below year-ago levels, Catenaa reported. And one affordability index hit its worst level in 21 years in July, Federal Reserve Governor Michael Barr said, a blunt measure of how far the dream of homeownership has drifted from the average paycheck.
What comes next depends on forces far from any open house. If tensions with Iran ease and oil trade routes reopen, inflation pressure could fade and yields could follow. If Wednesday’s inflation report or Friday’s jobs data surprise to the upside, the 10-year could climb further and take mortgages with it. For now, the fall buying season belongs to the patient, the well-funded, and the willing to negotiate.
