Multifamily Reckoning: The Apartment Boom’s Painful Comeback to Earth

Last updated: October 6, 2026

If you've been watching multifamily as your go-to commercial real estate play, the numbers deserve a hard look. A wave of maturing debt, climbing delinquency rates, and a brutal cost squeeze is reshaping the sector that dominated CRE portfolios for most of the last decade.

Executives at a recent Bisnow industry event spelled out what this means for anyone with skin in the game—and it isn't pretty.

Key facts

• Approximately $757B in multifamily debt comes due before 2028, with $1.8T on the horizon over the next decade
• Apartment values declined about 5% over a recent 12-month span, while broader commercial real estate values held steady
• Trepp reports CMBS multifamily loan delinquencies reached 8% in August, up from 6.5% a year prior
• Per-unit operating costs surged 37% from 2019 to 2026, reaching nearly $9,510 annually
• The 10-year Treasury yield topped 5.3%, its highest point since 2022, reshaping borrowing economics overnight

Why Multifamily Is Struggling Right Now

Here's the core problem: the math that worked in 2020 through 2022 no longer adds up.

During the zero-rate era, apartment owners loaded up on cheap debt. Rents in Sun Belt markets were surging at double-digit annual clips. The play seemed obvious—borrow cheap, watch rents climb, cash out.

That era is over. Rates aren't coming down fast, and rent growth has stalled or reversed in many markets. Operating expenses, meanwhile, have gone one direction: up. Harvard's Joint Center for Housing Studies tracks per-unit costs rising sharply over seven years. That's a significant jump—before accounting for any capital improvements.

Rialto Capital's Joe Bachkosky put it directly: owners are now spending just to maintain current rental income, not grow it. His firm—one of the most active special servicers handling CMBS loan workouts—now carries $14B in multifamily loans requiring restructuring. A third of loans recently transferred to Rialto's platform are multifamily. A decade ago, that figure was effectively none.

The delinquency picture tells the story. Trepp data shows 8% of multifamily CMBS loans delinquent in August, up from 6.5% twelve months prior. Only office carries worse delinquency rates among major property types.

This Isn't Your Standard Cycle Turn

What's different here compared to past downturns?

For one, the debt volume is staggering. Roughly $757B matures through 2028. When that much paper comes due in a high-rate environment, refinancing isn't just expensive—it can be impossible for assets whose income no longer supports the original valuation.

The 10-year Treasury cracking 5.3% seals it. That's the benchmark for most CRE lending. When that number climbs, cap rates have to climb too—which means property values fall. The loan doesn't care about paper values, though. It still needs repaying.

Some executives see second waves coming. Northwind Group's Ran Eliasaf predicted more firm failures similar to the Tides Equities default that wiped out a large Sun Belt portfolio. Many investors assumed rates would reverse course, Eliasaf noted. Current rate levels will leave many properties unable to sustain their debt service.

Others question whether lenders are learning anything. GoldenTree's Sam Friedland flagged loose underwriting on new apartment loans. He questioned whether lenders fully grasp the risk embedded in the use they're offering on new deals.

Oxford Properties' Andy Field put it plainly: even well-performing properties with pre-2023 debt "could be at risk of foreclosure" when maturities hit.

What This Means for You

If you hold multifamily assets, this is a stress-test moment. Review your debt maturity schedule now, not when the bank calls. Stress-test refinancing at current rates—not what rates might be in 18 months.

Say you own a mid-sized garden-style apartment complex in a secondary Sun Belt market. You bought at peak pricing with aggressive use during the rent-surge years. Operating costs have climbed substantially since then. Rents have flatlined or softened. Your debt matures soon. A lender will now underwrite that asset at higher cap rates than when you bought—which means the appraised value may fall below your current loan balance. You either inject equity, find a partner, or face a workout. That's not theoretical. That's the math facing thousands of owners right now.

If you're hunting yield elsewhere, note that office and retail have already repriced dramatically. Wafra's David Hamm, whose firm manages sovereign wealth fund capital, said retail has become a preferred allocation. "Office has been fully repriced," he noted. That repricing creates opportunities for contrarian buyers with patience and capital.

Bottom line

Multifamily isn't dead. The sector remains the largest commercial real estate asset class, and underlying housing shortages persist in many markets. But the golden-era return profile—that steady rent growth, that easy refinancing—is gone for now.

The next few years will separate those who planned from those who hoped. Watch delinquency data, watch Treasury yields, and watch for consolidation as well-capitalized buyers circle distressed sellers.

The smart money is already repositioning. The question is whether yours is too.

Key takeaways

• Stress-test any multifamily asset with pre-2023 debt against current rate environments before assuming refinancing is viable
• Operating cost inflation is eroding NOI across the sector—factor in nearly $9,500 per unit annually, up sharply from 2019 levels
• Other asset classes like retail and repriced office may offer better risk-adjusted returns in the near term for new capital
• Delinquency rates continue climbing—8% CMBS multifamily delinquency is the highest outside office and likely has further to rise
• Watch for distressed acquisition opportunities as weaker syndicators and overleveraged owners exit
