We're looking at two separate forces reshaping real estate math right now. Construction costs are climbing faster than rent. And refinancing equations aren't working anymore. CRED iQ analyzed $136B in multifamily debt maturing through December 2028. 23% of those loans cannot refinance without fresh equity. That's 31% of the total balance. The equity gap is $6.8B. Median shortfall is $25,000 per apartment unit. Loans written in 2021-2022 at the rate bottom are getting hammered. 46% of that cohort fall short. Old loans at 4%, new market rates 5.3-5.5%. That rate spread destroys the loan structure.
Geography matters. San Francisco 70% of maturing debt falls short. Denver 51%. Chicago 13%. Why the variance? Rent growth. High-growth metros saw NOI climb since underwriting. Without income growth, the math breaks. Construction costs since 2020 up 43%. Year-to-date 2026 nonresidential costs up 4.4%. JLL forecasts 3-6% annual increases through 2027. Material costs structurally elevated. Labor up 20% over five years. A project underwritten at $150 per square foot now costs $160. Both problems hit development brutally. Higher hard costs and tighter lending simultaneously. Construction lenders conservative. Permanent lenders pricing in higher risk. Supply constraints accelerate.
Multifamily CMBS special servicing at 8.75%. That's one in eleven loans in trouble. Blackstone's $1.3B multifamily CMBS loan hit special servicing in October. Institutional-grade property couldn't refinance at current terms. Texas saw $1B in troubled CRE loans in October alone. Fourth time in 2026. For operators: expect tighter lending, more equity requirements, higher permanent rates. Lock in fixed-price construction contracts early. For capital providers: opportunities in distressed debt and structured products. The 2026-2028 maturity window defines the next phase.
