National Apartment Association: Operating Costs Continue to Outpace Rental Revenue

Rental-housing operating costs continue to rise faster than income. Across 13,471 communities representing roughly 1.7 million units with data in both 2024 and 2025, rental revenue increased 2.7% while operating expenses rose 4.6%.
The margin pressure is broad-based. Market-rate communities recorded 2.4% revenue growth against 4.6% expense growth, while affordable communities saw revenue increase 2.9% against the same 4.6% rise in expenses.
NAA’s updated Dollar of Rent analysis shows how much of rental revenue is absorbed before reaching owners. On average, 27 cents of each rent dollar goes toward operating expenses and another 10 cents toward property taxes, while approximately 11 cents remains as the return to owners after other obligations are accounted for.
Utilities, insurance and property taxes remain important sources of cost pressure. With expenses continuing to outpace revenue growth, improving apartment demand and rent growth will not translate one-for-one into stronger NOI, keeping expense management an important part of the operating outlook.

Arbor Realty Trust – Chandan: Affordable Housing Trends Report 2026

Despite nearly 1.9 million multifamily completions between 2022 and 2025, the affordable housing shortage remains substantial. Roughly 11 million extremely low-income renter households were competing for just 3.8 million rental homes that were both affordable and available to them in 2024.
Rent burdens remain elevated across lower- and middle-income households. Renters earning less than $30,000 annually spent an average 57.6% of their income on rent in 2024, while the average rent-to-income ratio for households earning $30,000 to $75,000 rose to 27.1%.
The development pipeline is shifting toward affordability. Fully and partially affordable units represented 29.4% of tracked apartment completions in 2025 and are projected to account for 37.7% by 2028, even as the recent market-rate supply wave works through lease-up.
Financing support has also expanded. Higher GSE mission-driven requirements, increased LIHTC investment capacity, and the 21st Century ROAD to Housing Act have widened the channels through which capital can reach affordable housing, although elevated interest rates, construction costs, and limited public funding remain meaningful constraints.

September CPI Reaccelerates Rate Pressure on Rental Housing

Consumer prices rose 0.6% in September, the largest monthly increase of 2026, while annual inflation accelerated to 3.7% from 3.4% in August. Energy drove much of the increase, with gasoline prices jumping 9.1% during the month.
Underlying inflation was firmer but less dramatic. Core CPI rose 0.3% for the second consecutive month and 2.6% year over year, while shelter inflation edged up to 0.4% after two months at 0.3%.
The report materially shifted interest-rate expectations. Markets raised the probability of an October Fed hike to 43.7% from 22.1% immediately before the release, while the implied year-end federal funds rate increased 7 basis points. The 10-year Treasury yield also moved 3 basis points higher to 5.25%.
For rental housing, the long-term rate backdrop remains the more consequential constraint. A 10-year Treasury yield above 5% keeps acquisition and development financing expensive, limits the room for cap-rate compression, and raises the return thresholds required for new investment even as operating fundamentals improve.
