New multifamily construction starting in 2025 dropped sharply from the 2021 peak, deepening a supply shortage in the affordable housing market that is unlikely to be resolved for years. Amy Rubenstein, CEO of Clear Investment Group, says the situation is most difficult in C-class workforce housing, where new construction was already rare, and supply typically depends on older, higher-tier properties filtering down to lower price points over time.

“Construction starts in 2025 are so far below the peak of 2021 that we are not getting new supply delivered,” Rubenstein says. “Even when new buildings are completed, they are almost always A or B-class properties. The flow down to C class is even slower, and right now, less is being built overall.”

Clear Investment Group specializes in acquiring distressed workforce housing assets with more than 300 units in markets such as Ohio, Louisiana, Illinois, Alabama, and New York. The firm targets properties serving tenants earning $40,000 to $80,000 annually — workers in jobs such as janitorial services, hospitality, and trucking who earn too much to qualify for Section 8 vouchers yet still struggle with housing costs.

Filtering Pipeline Breaks Down

For decades, the affordable housing market has relied on a filtering process. As new A- and B-class apartments are built, older units age into C-class inventory, gradually expanding the affordable supply. This system depends on steady new construction to push existing properties down the quality ladder. When construction slows dramatically, as it has since 2021, the entire cycle breaks down.

Rubenstein notes that the surge in projects that began in 2021 and 2022 is still bringing new units to market, temporarily masking the shortage. As those projects finish without a similar pipeline to follow, the gap in affordable supply will widen.

“When you look at how much the pace of starts dropped in 2025 — when those units should have been coming online — you start to feel that lack of new inventory,” Rubenstein says.

The shortage is compounded by the fact that nearly all new construction targets higher-income renters. Developers building A- and B-class properties in 2025 are not adding to the affordable supply, leaving a growing mismatch between what is being built and what is needed.

Demand Stays Strong

Even as supply contracts, demand for affordable housing remains high and shows no sign of easing. Economic downturns often push renters into C-class units as those previously in B-class properties seek lower rents.

Rubenstein explains that a weaker economy typically moves renters down the quality ladder. “You might get someone in a B-class unit who now has to move to a C-class unit,” she says.

This creates a persistent imbalance. Regardless of broader economic conditions, the pool of renters seeking affordable units continues to grow while new supply remains limited. The result is a long-term deficit, not a temporary mismatch.

Absorption rates for affordable housing have slowed somewhat. Rubenstein attributes this to “mobility friction,” meaning the financial barriers lower-income renters face when moving, such as saving for the first month’s rent, deposits, and moving costs. This does not reflect a lack of demand, but rather the financial constraints of tenants.

“There is a very large shortage of affordable housing in the country overall, and that’s not improving anytime soon,” Rubenstein says.

Regional Rent Trends Diverge

Nationally, rents for affordable housing have remained mostly flat year-over-year, with about 1% growth. This average, however, conceals sharp differences between regions. Markets that suffered pandemic-era downturns — such as San Francisco, Chicago, and New York — are now experiencing strong rent growth as they recover. In contrast, cities that boomed during the pandemic — Austin, Nashville, Atlanta — are seeing rents decline as they work through excess supply.

These regional differences trace back to the uneven construction surge of 2021 and 2022. Overbuilt markets are now digesting new inventory, while underbuilt regions face tighter supply. Even in cities with declining rents, the long-term trend points to tightening as the construction pipeline narrows.

Clear Investment Group does not assume rent growth in its acquisition models, even in rising markets. The firm’s value-add strategy is to restore underperforming properties to average occupancy, rather than relying on future market appreciation. The broader supply shortage suggests that even conservative projections may prove too cautious, as reduced construction starts have a cumulative effect.

Institutional Interest in Workforce Housing

The ongoing supply-demand gap is attracting more institutional investors to C-class housing, a segment they have traditionally avoided. Rubenstein says more institutional buyers are now open to workforce housing, drawn by the persistent shortage and higher potential returns than those of A-class properties.

Clear Investment Group typically buys distressed properties at around 50% economic occupancy, stabilizes them, and sells to institutional buyers once performance improves. The firm assumes the operational risk of turnarounds, preparing assets for buyers seeking stable cash flow without the complexities of property rehabilitation.

While the company’s minimum acquisition size of 300 units meets institutional criteria, the level of initial distress — high vacancy and delinquency — usually falls outside the comfort zone of many large investors. Once stabilized, however, these properties become attractive to buyers seeking exposure to affordable housing with less operational risk.

Whether increased capital can address the shortage quickly enough remains uncertain. A significant rebound in construction starts would be needed to restore balance. Current economic conditions offer little sign that such a rebound is approaching.

Shortage Expected to Persist

With new construction activity at historic lows and demand for affordable housing remaining high, the supply shortage is likely to persist for years. Most new development targets higher-income renters, and the traditional filtering process that once expanded affordable inventory is no longer functioning as intended.

For investors and policymakers, these trends point to a protracted period of tight supply and upward pressure on rents for workforce housing. Unless construction starts rebounding dramatically, the affordable housing gap will continue to widen, leaving millions of renters with few viable options and little relief in sight.
