Where Multifamily Inventory Is Tightening and Building in 2026

National multifamily listings showed little movement between November 2025 and March 2026, according to LoopNet data, but city-level data tells a different story.

Nationwide, listing count fell by just 2.3%, but inventory in some individual markets grew by over 20% in some markets, and fell by more than 10% in others over the same period. That divergence carries direct implications for deal availability, seller behavior, and competitive dynamics depending on where you're planning to invest in multifamily.

Listing count movement is a behavioral signal. It broadly reflects what owners are doing before those decisions show up in asking prices. Tightening inventory can reflect seller conviction, while expanding inventory points to seller urgency in softening markets or seller confidence in stronger ones. And combining either trend with price direction gives you a more complete picture than either does alone.

How we measured

This analysis is based on LoopNet multifamily listing data from November 2025 through March 2026. To ensure city-level figures are reliable, only cities with a minimum of 40 active listings in both periods were included. Cities where mean and median asking prices diverged significantly were excluded, as large gaps between the two measures typically indicate that a small number of outlier listings are distorting the average rather than reflecting multifamily price trends.

A shifting multifamily market trend

LoopNet listing data for multifamily properties for sale from November 2025 through March 2026 splits across two patterns. The first was markets where inventory tightened alongside rising prices, concentrated in Midwest and coastal cities. The second was markets where inventory grew, with some showing seller exit pressure, while others reflect seller confidence.

Some, including the Denver multifamily market and Atlanta multifamily market, fit the broader inventory-building, price-softening pattern visible across Sun Belt markets, though their individual inventory moves were too modest to feature on their own.

What Markets Had a Decrease in Multifamily Inventory?

Philadelphia and Detroit are seeing fewer sellers and higher asking prices.

Two cities in the dataset saw listing counts fall between November 2025 and March 2026 while median asking prices rose:

• Philadelphia listings fell 12% while median asking prices rose 31%
• Detroit listing count was down 9%, with a 48% increase in median asking price.

In each case, a shrinking seller pool coincides with rising prices, the combination that most directly signals sellers gaining pricing power in the available inventory.

Philadelphia saw concentrated tightening in mid-market products.

The number of Philadelphia multifamily properties for sale fell 12% between November 2025 and March 2026, from 264 to 233 active listings, but the decline was even more pronounced in the mid market. The number of listings priced between $650,000 and $2.4 million dropped nearly 17%.

Meanwhile, in the same time period, the median asking price rose 31% from $996,500 to $1.3 million, while the average rose just 11%. The gap between mean and median indicates that both the inventory compression and the price movement are concentrated in mid-market products rather than at the high end.

That mid-market tightening is happening against a broader backdrop of peak new supply. According to a March 2026 Northmarq analysis, Philadelphia's multifamily market entered 2026 at its highest delivery volume in more than a decade, with approximately 9,000 units expected to complete over the course of the year.

But that new supply is concentrated in the urban core. The same Northmarq report notes that for well-located assets in supply-constrained corridors, tightening vacancy and improving rent growth are pointing toward upward pricing pressure as the year progresses. The LoopNet listing data reflects that dynamic in the mid-market tier specifically.

Detroit's inventory decline is paired with the strongest price signal in the dataset.

The Detroit multifamily market saw its listing count fall 9% between November 2025 and March 2026, from 98 to 89 listings. Among the tightening markets in the dataset, the city also showed the strongest accompanying price movement: the average asking price rose 49%, closely tracking the median's 48% gain.

Supply conditions in Detroit shed more light on that pricing change. According to PwC and ULI's Emerging Trends in Real Estate 2026, Detroit is among the markets expected to be top rent growth performers, driven by weak supply growth.

A February 2026 Yardi Matrix report published by Multi-Housing News adds context on where that growth is concentrated: in Detroit, rent growth has favored Renter-by-Necessity properties, suggesting the demand driving performance is coming from workforce housing rather than the luxury tier, consistent with the market's lower price points relative to other cities in this analysis.

Even with a significant median price increase, which was the largest percentage increase of any market in the analysis, Detroit had the lowest entry point price among the markets with tightening supply in both November and March.

What Markets Saw Inventory Growth?

Washington, D.C., Kansas City, and San Antonio listing counts grew, with differing price signals.

Rising inventory doesn't always mean the same thing. In softer markets, an increase in listing counts can signal owners evaluating multifamily exit strategies ahead of expected price declines and a market where more supply enters the market without corresponding demand.

In stronger markets, the same directional signal reflects an entirely different reality, where owners list because conditions support their price expectations. In the November to March timeframe, San Antonio followed the first pattern, while Washington, D.C. and Kansas City followed the second.

San Antonio's growth reflects a shifting market.

Listings in San Antonio increased 12% from 82 to 92 listings, while median asking prices fell 11% from $898,000 to $799,000. The average asking price, however, tells a more nuanced story. It declined just 1.3%, a stark contrast to the median.

The gap between mean and median asking price is driven by a more concentrated growth in lower-priced listings. Listings below market median grew 43% from November to March, despite overall market growth of 12%. The disproportionate growth in lower-priced inventory is what pulled the median down while leaving the mean largely unchanged.

That pattern is consistent with broader conditions in the San Antonio multifamily market. According to a March 2026 analysis by the Federal Reserve Bank of Dallas, San Antonio has seen some of the sharpest rent declines in Texas, with landlord concessions expected to continue through mid-2026. A separate CoStar analysis of the San Antonio rental market reported by the San Antonio Report in March 2026 puts San Antonio's multifamily vacancy rate at 15.7%, which is the highest among major multifamily markets nationally.

Those conditions help explain why smaller, lower-priced properties are entering the for-sale market at a faster rate. For buyers watching for distressed entry points, that concentration of lower-priced inventory entering the market at once is worth tracking.

Washington D.C. and Kansas City are attracting more sellers as prices rise.

The number of Washington, D.C. multifamily properties for sale grew 21%, from 155 to 187, while the median asking price rose 13%. Kansas City saw a similar trend: listing count grew 17%, from 46 to 54 listings, while the median asking price increased 19%.

In both markets, inventory growth is coinciding with price appreciation rather than working against it, and the rising listing count in each city is not translating into downward price pressure.

For D.C., part of the context is on the supply side. According to a February 2026 Northmarq market report, the regional construction pipeline ended 2025 at its lowest level in a decade, with annual deliveries projected to fall below 10,000 units in 2026.

Fewer new units entering the market reduces the supply pressure that would otherwise compete with existing listings and helps explain why more sellers are entering the market without pushing prices down. The same Northmarq report cautions, however, that federal workforce reductions are weighing on demand and that the regional investment outlook remains cautious. For investors, performance in this market is likely to vary significantly by asset class and submarket.

Kansas City is being driven by demand fundamentals. According to PwC and ULI's Emerging Trends in Real Estate 2026, Kansas City is among the markets expected to be top rent growth performers, driven by population growth, job growth, and comparatively affordable apartments. That demand backdrop is consistent with Yardi Matrix data showing Kansas City ranked fourth nationally in advertised rent growth in January 2026, and helps explain why rising listing counts in the market aren't translating into price compression.

What Inventory Movement Reveals That Asking Prices Don't

Inventory movement can point to where a market is heading.

City-level LoopNet data from November 2025 through March 2026 shows inventosry and price diverging in ways that directly affect deal sourcing.

Philadelphia and Detroit have fewer sellers and higher prices. Washington D.C. and Kansas City have more sellers and higher prices. San Antonio has more sellers, lower prices, and a concentration of new supply at the lower end of the market. Each pattern carries different implications for deal availability and competitive dynamics.

In a market moving in two directions, choosing among the best cities for multifamily investing requires knowing which direction applies to the specific city and price tier you're underwriting. That distinction matters more than the national headline.
