Sunbelt financing stress

The pressure in Sun Belt real estate did not start with empty buildings. It started with a boom. Developers spent the low-rate years flooding fast-growing markets with apartments, especially in the South and Mountain West. In 2024, the U.S. completed nearly 592,000 multifamily units, the biggest one-year jump since 1974, and that wave landed heavily in Sun Belt metros (trepp.com). RealPage’s data shows the surge was still running into 2025, with Dallas, Phoenix, and Austin each delivering more than 27,000 units on an annual basis and leading the country in new supply (realpage.com). That much new inventory changes the market fast. Owners who had been raising rents with ease suddenly had to fight for tenants. RealPage found that high-supply Sun Belt markets were still sitting well below their own pre-pandemic occupancy norms in early 2025. Fort Worth was down 200 basis points. Austin was down 170. Charlotte, Orlando, and Nashville were each down 150 (realpage.com). Yardi Matrix’s year-end 2025 report said the weakest rent performance in the country was “largely confined” to the Sun Belt, where elevated new supply kept pricing under pressure, while national asking-rent growth for 2025 fell to zero (yardi.com). That would be painful in any cycle. It is worse in this one because so many properties were financed with short-term, floating-rate debt. When rates reset higher, debt service rose immediately, but rents did not. Trepp says higher operating costs made the squeeze tighter still. Over the past five years, repairs and maintenance rose 16.5%, real estate taxes 16.6%, utilities nearly 21%, and property insurance roughly doubled for multifamily owners (trepp.com). A property that looked fine in a 2021 underwriting model can look fragile now even before a single unit goes dark. The debt stack behind that fragility is enormous. Trepp estimated total U.S. commercial real estate debt at $4.8 trillion in the second quarter of 2025, with banks holding $1.83 trillion and a significant share of bank and securitized debt maturing through 2026 (trepp.com). The Mortgage Bankers Association put 2025 maturities alone at $957 billion, including $231 billion in CMBS, CLOs, and other ABS and $452 billion of mortgages serviced by depositories (mba.org). That is why talk about “roughly $3 trillion” of floating-rate exposure resonates even if the exact figure varies by definition. The system is carrying a huge pile of debt that must either refinance, extend, or break. Lenders know this, which is why underwriting has become the whole game. The FDIC warned banks with CRE concentrations in late 2023 to strengthen capital, reserves, and risk management as refinancing risk and weaker property performance spread through the market (fdic.gov). A New York Fed staff report then described how “extend-and-pretend” behavior can push problems forward instead of resolving them, reducing new credit and adding to the maturity wall (newyorkfed.org). When lenders stop assuming rent growth will bail everyone out, the boring details start to matter more than the story. Those details are operational. In 2026, CBRE expects rent growth to keep lagging pre-pandemic norms because so much new supply is still available for lease in the Southeast, South Central, and Mountain regions (cbre.com). That means landlords cannot underwrite their way out of weak execution. They need tighter leasing, lower turnover, cleaner expense control, and realistic pricing. In a market like Austin or Phoenix, where thousands of new units arrived before the old pro formas had time to die, the difference between a survivable loan and a distressed one can be a few points of occupancy and an insurance bill that no longer fits on last cycle’s spreadsheet.
