Apartment Investors Are Underwriting a Wage Growth Story That Does Not Exist.

The multifamily bull case has a structural problem. Rent growth, the engine of nearly every apartment deal underwritten between 2021 and 2023, requires either accelerating household formation or real wage gains for the renter cohort. Neither is materializing at the pace embedded in investor models.
According to the Federal Reserve Bank of Cleveland, cumulative real hourly wage gains for workers at the 25th percentile remain more than $0.60 below what pre-pandemic trends would have predicted through Q3 2025. Median workers tell the same story. Yet apartment investors, per CBRE's quarterly underwriting survey, continue to assume 2.8% to 3.3% annual rent growth over three-year hold periods. That gap between assumption and labor market reality is not a rounding error. It is the thesis.
Chart 1. Real Wage Growth vs. Median Asking Rent (Indexed, 2019 = 100)
The wedge between the navy line and the dashed lines is not recoverable through inflation alone. Sticky shelter costs in a flat-wage environment increase rent burden. They do not increase rent payment capacity. Harvard's Joint Center for Housing Studies documented this in detail: by 2023, a record 22.6 million renter households were cost-burdened, spending 30% or more of income on rent. Critically, the fastest-growing cost-burdened cohort is now middle-income renters earning $45,000 to $74,999 annually, up 4 percentage points in a single year.
Chart 2. Cost-Burdened Renter Households (Millions)
This is not simply an affordability story for low-income renters. It is a demand ceiling story for the asset class. When 41% of middle-income renter households are already cost-burdened, the marginal ability to absorb further rent increases is structurally constrained regardless of what CPI does.
Supply has made the problem worse. Developers added more multifamily units in 2024 and 2025 than at any point since the 1970s. The national vacancy rate reached 7.2% in early 2026, per Apartment List, more than two full percentage points above pre-pandemic norms. Sun Belt markets that led the investment frenzy are now absorbing the consequences: Austin rents down 5.1% year-over-year, Denver down 3.3%, Phoenix down 2.6%.
Chart 3. National Multifamily Vacancy Rate (%)
The underwriting record tells the rest of the story. At the peak of the cycle in 2021, apartment rents actually rose 17.8%, per Apartment List, validating aggressive models. Investors responded by locking in rent growth assumptions of 3.6% annually for forward-looking deals. What followed was three consecutive years of negative or near-zero national rent growth. CBRE's Q2 2025 survey shows investors have only modestly revised assumptions downward, to 2.8% for core assets and 3.3% for value-add.
Chart 4. Investor Rent Growth Assumptions vs. Actual National Rent Growth (%)
The gray bars in 2023, 2024, and 2025 do not represent a bad year. They represent a structural misread of the renter cohort. Investors who underwrote deals in 2021 and 2022 using 3% to 5% annual rent growth assumptions compounded over a five-year hold are now sitting on NOI shortfalls that no cap rate recovery can fully offset.
The Honest Assessment
Apartment investors are not waiting for wage growth. They are using inflation as narrative cover for deals that required cap rate compression to pencil. The Federal Reserve's pause gives them a story. The income statement does not support it.
Real wage growth for the 25th and 50th percentile renter cohort remains more than $0.60 per hour below pre-pandemic trend lines. Vacancy is at a multi-decade high. Cost-burden rates are at record levels. And investors are still underwriting 2.8% to 3.3% annual rent growth into deals closing in 2026.
That is not optimism. That is a model that has not been updated to reflect the market it is pricing.
