Signal
U.S. apartment rents slipped again in September, marking the steepest seasonal decline in more than 15 years. The national average fell to $1,712 (–0.3 % MoM) as record deliveries overwhelmed absorption. For capital markets, that reversal has become an underwriting reset: assumptions once anchored to perpetual growth are being recast around income durability and disciplined leverage.
The Supply Surge
Developers are completing roughly 500,000 units in 2025, the crest of projects financed during 2022–23’s credit window. Sunbelt metros – Austin, Phoenix, Raleigh – absorbed barely half last year’s leasing pace, pushing rents down 3–4 % YoY. In contrast, San Francisco (+6.1 %) and San Jose (+3.8 %) proved that scarcity and regulation still sustain pricing power. The divergence is stark: excess supply now punishes yield, while constraint protects it. Multifamily has reverted to a local, not national, equilibrium.
Underwriting Tightens
Across the lending stack, rent-growth inputs are being trimmed to 0–2 % for 2025 and vacancy assumptions raised toward 10 %. “We’re back to fundamentals – tenant retention, expense control, not rent inflation,” noted a national multifamily credit officer. Pro formas that once baked in 4 % annual lifts now model flat NOI through 2025. Debt service coverage ratios are stressed at zero growth; lenders reward experienced sponsors who can manage concessions without eroding cash flow. In turn, appraisers are applying heavier weight to trailing income rather than forward pro formas.
Capital Behavior Shifts
The 10-year Treasury yield near 4 % has steadied financing costs around 6 % for multifamily debt. Yet higher coupons compress equity returns – target IRRs that once touched 12 % are now 8–9 %. Opportunistic money is tilting toward private-credit strategies offering double-digit yields. Still, core-plus investors are re-emerging in supply-constrained Midwest and coastal metros, where stable rent rolls provide clarity. Capital is no longer chasing growth; it is pricing discipline as the new alpha.
Bifurcated Performance
Class A properties with amenity depth are holding line on rents, while older workforce assets concede multiple weeks of free rent. Leasing teams report heavier renewal negotiations and slower trade-outs. Markets such as Denver, Salt Lake City, and Raleigh are seeing mid-90 % occupancy with elevated economic vacancy from concessions. Meanwhile, Milwaukee and Cleveland (+0.1 % MoM) illustrate how affordability and limited pipelines buffer demand. The market’s new rule: stability is a premium product.
Macro Undertow
Federal Reserve Chair Powell’s hint that quantitative tightening “may be coming into view” cooled yields and sparked relief across CRE debt desks. Yet lower rates cannot offset overbuilding. Even if financing eases, supply absorption will dictate rent recovery. The paradox is clear – capital costs may fall before fundamentals heal, leaving valuations unsettled and cap-rate spreads wide. Price discovery will persist until late 2026 when construction starts finally recede.


The next year will test operator agility more than asset conviction. National occupancy, now about 94.5 %, could slip another 50–100 bps as lease-ups flood high-growth metros. Expect concessions and flat trade-outs to define 2025 NOI performance near 0 %. By late 2026, diminished starts and ongoing household formation should restore ~3 % rent growth in balanced markets. Lenders will favor recapitalizations and proven sponsors until that adjustment completes.
Stability isn’t relief — it’s discipline priced in.
