Affordability Constraints and Lock-In Effect Set to Stall Housing Market Recovery in 2025

Persistent Affordability Challenges Define 2025 Outlook

The U.S. housing market is unlikely to see a significant rebound in 2025, according to the latest economic forecast from Fannie Mae’s Economic and Strategic Research (ESR) Group. The primary culprits: entrenched affordability challenges and what economists refer to as the “lock-in effect,” where existing homeowners with low mortgage rates are reluctant to sell and trade up at today’s elevated rates.

Despite expectations of modest economic growth and nominal wage increases, these two forces are expected to maintain downward pressure on housing activity. Fannie Mae economists foresee only a slight increase in existing home sales from their current 30-year lows, even as the broader U.S. economy continues to expand at an above-trend pace.

Five Key Predictions from Fannie Mae for 2025

The ESR Group offered five core forecasts shaping their 2025 housing market outlook:

1. Mortgage Rates to Remain Above 6%
   Rates are expected to decline modestly over the year but stay above 6%, with periodic spikes due to volatility in the bond markets and inflation expectations.
2. Existing Home Sales to Remain Subdued
   While a minor improvement is expected, sales will likely remain stuck near historic lows due to ongoing affordability challenges and low housing inventory.
3. New Home Sales to Outperform
   New construction, especially in high-growth areas like the Sun Belt, will continue to serve as a relative bright spot. Builders are adjusting to target first-time buyers, which could keep sales relatively robust.
4. Home Price Growth to Cool
   National home price growth is expected to decelerate, offering some relief to buyers—but not enough to overcome the affordability gap created by high rates and limited supply.
5. Multifamily Housing to Stay in Holding Pattern
   Development in the multifamily sector is likely to stagnate, constrained by financing challenges and elevated construction costs.

The Lock-In Effect Continues to Suppress Inventory

A central factor keeping inventory low is the lock-in effect, whereby homeowners who refinanced or bought homes during the era of ultra-low interest rates are unwilling to move and face higher borrowing costs. This limits the number of homes available on the market, further pressuring prices and restricting options for new buyers.

“From an affordability perspective, we think 2025 will look a lot like 2024,” said Mark Palim, Chief Economist at Fannie Mae. “Mortgage rates above 6 percent, home price growth easing but still positive, and supply still below pre-pandemic levels.”

Regional Disparities Highlight a Localized Market

Despite nationwide challenges, the market will not behave uniformly. In regions like the Sun Belt, where housing development has been more aggressive and tailored to first-time buyers, stronger activity is expected. In contrast, areas such as the Northeast, where housing supply is tightly constrained, are unlikely to see any substantial improvements.

Palim also highlighted that wage growth is expected to outpace home price appreciation for the first time in over a decade, a trend that may begin to chip away at affordability challenges, albeit slowly. This could provide some relief over time, but the overall national picture remains one of constraint and limited growth.
