Homebuyers face 6.7% mortgage rates in 2027 as forecasts rise

Fannie Mae and the Mortgage Bankers Association both revised 2027 forecasts to an average 30-year fixed rate of 6.7 percent, up from 6.3 percent and 6.5 percent, as persistent inflation keeps Treasury yields elevated.

"Most of the recent affordability challenges have come from increased mortgage rates. Home prices have actually been falling on a year-over-year basis throughout 2026 at the national level," said Joel Berner, senior economist at Realtor.com. "Behind the scenes though, inflation is the real culprit."

The current average 30-year fixed rate stands at 6.81 percent, according to Mortgage News Daily, just 4 basis points below its 52-week high of 6.85 percent. The 10-year Treasury yield is hovering near 4.72 percent, well above its 50-week exponential moving average of 4.415 percent. The Fed's preferred PCE inflation measure rose 3.7 percent in July from a year earlier, while core PCE increased 3.3 percent — both above the central bank's 2 percent target.

For prospective buyers, the math is unforgiving. Home prices remain roughly 59 percent above 2020 levels and are projected to climb another 2.2 percent in 2027, according to a Fannie Mae survey of more than 100 housing experts. Meanwhile, average hourly earnings declined at a 1.66 percent annualized rate after adjusting for inflation during the first half of 2026, according to an analysis of federal data by the Hamilton Project at the Brookings Institution.

Inflation's grip on the bond market

Mortgage rates track the yield on the 10-year Treasury note, which is influenced by expectations for inflation and economic growth. When inflation is expected to remain high, Treasury yields and mortgage rates rise with it. Fed Chair Kevin Warsh's Jackson Hole inflation warning pushed bond yields higher, with the 10-year Treasury touching 4.74 percent on Aug. 21 before settling near 4.72 percent.

"Economic reality has forced even the most optimistic interest rate forecasters to project a higher rate environment than anticipated earlier this year," said Marty Green, a residential mortgage lending attorney at Polunsky Beitel Green. Green pointed to renewed tariffs and the war in Iran as factors that could keep inflation high and make lower mortgage rates harder to forecast.

The Fed held its benchmark rate at 3.50 percent to 3.75 percent in July, although three policymakers favored a quarter-point increase. Its next policy meeting is scheduled for Sept. 15-16. The August employment report, due Sept. 4, could determine near-term relief — a weaker-than-expected jobs report could pull Treasury yields lower, while strong wage data could reinforce expectations for tighter policy.

The housing market is already showing the strain. Mortgage applications declined 1 percent in the week ended Aug. 21, according to the Mortgage Bankers Association, with refinancing applications down 17 percent from a year earlier. New-home sales fell 10.5 percent in July to a seasonally adjusted annual rate of 607,000, while available supply climbed to 9.6 months. The median new-home price was $393,800.

Builders face higher costs, less supply

Tariffs are raising the price of materials used throughout a home, including lumber, plywood, steel, aluminum, copper and cement, according to the National Association of Home Builders. Builders are also dealing with persistent shortages of skilled workers. The war in Iran is adding to the expense — higher oil prices have pushed up gas and diesel prices, making building materials more expensive to produce and transport.

"What this leads to is less (in quantity) and less affordable inventory being delivered to the housing market," Berner said.

Realtor.com's own forecast expected mortgage rates around 6.3 percent for the rest of 2026, an outlook the company has since said "may prove too optimistic" as inflation and the war in Iran put renewed upward pressure on rates.

For would-be buyers, waiting until 2027 may not make buying a home much cheaper. Rates remain well below the extreme levels seen in the early 1980s, but the 30-year average has moved back up after reaching 6.43 percent in early July, making affordability more difficult heading into the fall housing season. The next major test comes with U.S. labor data — July job openings are due Tuesday, followed by the August employment report Friday, Sept. 4, at 8:30 a.m. ET. A weaker-than-expected jobs report could pull Treasury yields lower and offer mortgage rates some relief, while strong employment or wage data could reinforce expectations for tighter Fed policy.
