Apartment Supply Cools, Limiting Broad Rent Relief

The U.S. rental market is sending two different signals at once: vacancy remains elevated in parts of the South, but the apartment construction surge that helped restrain rent growth is losing momentum.

That split matters for renters. Households in oversupplied markets may still find concessions or lower asking rents, while renters in tighter markets could see less relief as fewer new apartments enter the market.

Apartment completions are well below the recent peak

RealPage, an industry apartment-market analysis provider, estimated that about 77,700 market-rate apartments were completed nationally in the second quarter of 2026, up from roughly 74,200 in the first quarter. The second-quarter total remained well below the approximately 160,000-unit quarterly peak reached in the third quarter of 2024.

RealPage estimated that about 340,200 apartments were delivered in the year ending in the second quarter. The company said that annual total fell below the decade norm for the first time in three years. Annual demand was estimated at about 271,300 units, below the decade average of roughly 340,000.

Fewer completions do not automatically produce higher rents. Existing vacancies, household formation, concessions and local economic conditions can delay or weaken that effect. Over time, however, a slower construction pipeline can reduce the supply cushion that has increased competition among landlords.

Vacancy remains highest in the South

The Census Bureau’s July 28 Housing Vacancy Survey put the national rental-vacancy rate at 7.3% in the second quarter. That was virtually the same as the first quarter’s rate and was not statistically different from the 7.0% rate reported for the second quarter of 2025.

The South had the highest regional rental-vacancy rate at 9.5%, followed by 6.9% in the Midwest, 5.9% in the Northeast and 5.3% in the West. The Census Bureau said the Northeast rate was higher than a year earlier, while the year-over-year changes in the Midwest, South and West were not statistically different.

RealPage’s separate market-rate apartment estimates show a similar regional divide. The South was the only region with apartment occupancy below 95% and the only region with annual apartment-rent declines in the company’s second-quarter data. RealPage identified San Antonio, Austin, Phoenix and Charlotte among markets under notable rent pressure, while Tampa and Las Vegas also recorded declines in some segments. Conditions vary substantially by property, neighborhood and apartment class.

RealPage estimated national apartment occupancy at 95.5% in the second quarter. Effective asking rents rose 1.4% from the first quarter but remained 0.2% below year-earlier levels. Concessions were offered on about 24.6% of apartments, with an average concession equal to 7.6% of rent.

The result is localized relief rather than a national rent decline. RealPage reported annual rent growth in supply-constrained coastal and Midwest markets even as parts of the South and Sun Belt continued to experience elevated supply, weaker occupancy and discounts.

Three rent measures tell different stories

The Census Bureau reported a $1,531 median asking rent for vacant-for-rent units. That is an asking-rent measure for units currently available and should not be treated as the average rent paid by all existing renters.

RealPage’s figures cover market-rate apartments and include effective asking rents that account for concessions. They are not the same as the Census measure and are not federal statistics.

The Bureau of Labor Statistics measures rent inflation through the Consumer Price Index. In June, the rent-of-primary-residence index rose 2.8% from a year earlier, while the broader shelter index rose 3.3%. Those measures generally move more slowly than advertised rents because many tenants remain under existing leases and the CPI tracks the housing stock rather than only newly listed units.

What the shift means for households

Renters in markets with high vacancy should compare the advertised rent with the concession-adjusted cost over the full lease term. A free month, waived fees or other incentive can materially change the effective monthly payment, but the benefit may disappear at renewal.

Renters in tighter markets are less likely to see broad discounts if construction slows and available units remain limited. National averages can therefore obscure large differences between regions and even between nearby properties.

Builders, landlords and local officials will also be watching the future pipeline. Construction Dive, citing Dodge Construction Network, reported that multifamily starts slipped 0.4% month over month in June. Starts do not translate immediately into completed apartments, but continued weakness could eventually limit the number of new units available to renters.

What to watch next

The most useful indicators over the next several quarters will be apartment starts and completions, vacancy and occupancy rates, concession levels and regional rent trends. The next BLS CPI release is scheduled for August 12, 2026. The Census Bureau’s next Housing Vacancy Survey release is scheduled for October 28, 2026.

The construction surge has created a temporary cushion for some renters, but broad affordability relief is not guaranteed. The outlook will depend on whether demand, new supply and regional vacancy move back toward balance—and whether the markets with the most new apartments can absorb them.
