Fannie Mae's new forecast pushes mortgage relief past 2027

Fannie Mae's Economic and Strategic Research group publishes a housing forecast every month, and the October edition, dated Oct. 12, marks a sharp break from September. The group now expects the 30-year fixed mortgage rate to average 7.4% in the fourth quarter of 2026 and 7.5% in every quarter of 2027. In its Sept. 11 forecast, the same quarters were pencilled in at 6.8% and 6.7%.

From easing to tightening

The revision changes the shape of the path, not just its level. September's forecast had rates easing slightly into 2027 and then holding flat at 6.7%; October's has them stepping up and staying there. For full-year 2026 the average moves to 6.7% from 6.5%, which implies most of the change is concentrated in the final quarter and beyond. Fannie Mae's tables do not attribute the shift to a single cause, but the timing coincides with the energy-driven jump in inflation and a long end of the Treasury curve that has repriced higher.

Fewer sales, fewer starts

Higher rates feed straight into turnover. Fannie Mae cut its 2027 total home sales forecast to 4.713 million from 4.882 million, a reduction of 169,000, or about 3.5% by our calculation. Existing-home sales for 2027 were lowered to 4.061 million from 4.215 million. The 2026 total moved down to 4.672 million from 4.692 million, so this year is largely locked in and the damage falls on next year.

Construction is not spared. Total housing starts are now seen at 1.341 million in 2026 and 1.301 million in 2027, down from 1.351 million and 1.327 million. Fewer starts in a forecast that also expects slower price growth points to builders pulling back rather than chasing volume.

Prices: firm now, flat later

The price outlook splits in two. Fannie Mae raised its 2026 home price growth forecast to 2.7% from 2.3%, consistent with tight inventory as owners with low locked-in rates stay put. But it cut 2027 growth to 0.6% from 1.0%. That is the lock-in effect at work: supply stays scarce enough to hold prices up in the near term, while affordability eventually caps them.

The AlphaGen read

The October forecast is a meaningful signal because it comes from one of the two government-sponsored mortgage enterprises, and it moves in the opposite direction from a month ago. If rates track this path, the housing market faces another year of low turnover, which weighs on mortgage originators, brokerages and home-improvement demand tied to moves. The key swing factor is the 10-year Treasury yield: any relief there would likely show up quickly in mortgage rates, but Fannie Mae is no longer assuming it.
