For more than a decade, the U.S. real estate market has faced a growing imbalance between supply and demand for housing. Urban regulations, rising construction costs, and reduced land availability have kept vacancy rates at historic lows, especially in the multifamily segment. 

However, a recent announcement by the Federal Housing Finance Agency (FHFA) —the entity that oversees Fannie Mae and Freddie Mac, the two agencies responsible for backing nearly 40% of multifamily financing in the United States—opens a window of optimism. The increase in the multifamily financing cap starting in 2026 introduces positive signals that could boost the origination of new projects and improve the sector's prospects in the coming years. 

Housing supply: a market that is unable to respond 

The housing stock in the United States has grown insufficiently in response to the expansion of demand since 2008. Vacancy rates—both for owners and renters—remain at historically low levels, reflecting a market where supply is unable to adjust.
This rigidity is mainly due to land use restrictions, reduced availability of developable land, and increasingly lengthy and costly construction processes. 

The other side of the supply deficit is the deterioration of affordability. The price-to-income ratio is at multi-decade highs, while the mortgage payment-to-income ratio for a first-time buyer exceeds 30% of household income.
In the rental market, the rent-to-income ratio is at its highest level since 1980, particularly affecting essential workers who depend on more affordable multifamily units. 

Goldman Sachs estimates that the US needs between 3 and 4 million additional homes to restore affordability. Regulatory easing could add around 2.5 million units over the next decade, but regulatory fragmentation and low productivity in the sector continue to limit the speed of adjustment. 

The FHFA cap increase: a positive sign for multifamily and an opportunity for managers 

On November 25, the FHFA announced that by 2026, it will increase by 20.5% the multifamily financing limits that Fannie Mae and Freddie Mac can acquire or guarantee, reaching US$ 88 billion per agency.
The goal is to ensure adequate levels of liquidity and sustain greater activity in the multifamily market, just at a time when demand for affordable housing continues to grow. 

For investment managers, this announcement represents a particularly significant opportunity in the Class B/C multifamily and workforcesegment, where the structural supply deficit and resilient demand are combined with improved financing conditions.
The expansion of credit facilitates the structuring of projects with more competitive financial costs, drives refinancing and repositioning, and favors the development of new units in a segment that has historically been undersupplied and is fundamental to affordable housing. 

In a market where housing demand continues to grow and supply lags behind, regulatory signals for 2026 represent a possible turning point. Increased multifamily financing, coupled with stability in the workforce segment, suggests favorable conditions for affordable housing projects.
The interaction between structural deficit and increased credit availability creates an environment where multifamily housing is once again consolidating its position as a strategic focus within real estate investment opportunities.
