The rhythms of the nation’s rental market are no longer following the same beat. What used to be a predictable cycle of rent rises through late summer and cooling prices in fall has unraveled, disrupted by years of heavy apartment construction and changing migration patterns.
According to Apartment List’s latest national rent data, rents have been declining monthly since August — a dip that began earlier than usual and signals how far the market has diverged from its old seasonal norms. May used to mark the height of rent growth each year, but since 2023, the market has peaked in March as post-pandemic shifts continue to ripple through housing demand.
The national median rent ended December at $1,356, 0.8% lower for the month and down 1.3% year-over-year. From the high point reached in 2022, rents have now fallen 5.9%. More telling than the numbers themselves is what they reveal: even after the surge in demand during the pandemic, the market is reacting not to a lack of renters but over an influx of new supply.
Developers added more than 600,000 multifamily units to the market in 2024 — the largest annual increase since 1986, Apartment List reported. Completions eased in early 2025, but the 243,000 new units delivered in the first half of the year still ran 31% above the 10-year average. While projects under construction have declined “considerably” from the peak, they remain “solidly above the long-run average,” ensuring the effects of oversupply will linger in many metros.
The imbalance is regional. Of the 54 major U.S. metros, 51 saw month-to-month rent declines in December, with year-over-year drops in 33. The softest conditions are concentrated in Sun Belt and Mountain West markets, where the building spree has been most pronounced. Austin led the downturn with a 6.6% rent decrease over the past year. By contrast, a tighter supply in older markets is producing the opposite trend. Providence recorded the strongest rent growth among large metros, up 5.6%.
Listings are also sitting longer. The average unit now takes 39 days to rent, three days more than last year and the longest stretch since 2019. For investors and property managers, that means adapting to a market where prices don’t just move seasonally — they’re being structurally reshaped by years of construction that piled up faster than demand.
