US Apartment Rents Dip in August, But Annual Growth Speeds Up

What the data actually shows

Two of the most closely watched apartment-rent trackers in the country released their August 2026 readings within days of each other, and both point to the same underlying story even though their headline numbers differ. Apartments.com, owned by CoStar Group, reported that the national average rent slipped -0.03% in August, to $1,751 from a revised $1,752 in July — ending eight straight months of monthly increases 16. Apartment List, using a different methodology built on median rents and repeat-transaction data, reported the opposite monthly direction: a 0.1% increase to $1,390, marking its seventh consecutive monthly gain and the first positive August reading since 2022 7. CNBC's coverage leaned on the Apartment List figures, framing the market as "finally turning positive" as vacancies fall and new supply tapers off 3.

The apparent contradiction is really a matter of definitions. Apartments.com tracks a national average; Apartment List tracks a national median built from actual leased transactions rather than asking prices, and controls for differences in unit composition 7. Both, notably, agree on the more important trend line: annual rent growth is accelerating even where monthly figures are flat or slightly negative. Apartments.com found annual growth of 1.3% in August, up from a revised 1.1% in July and matching the pace from a year earlier 6. Apartment List's year-over-year figure is still negative, at -0.8%, but it has been climbing steadily for four months after bottoming at -1.6% in April 7.

A market defined by absorption, not just construction

Both trackers tie the shift to the same structural cause: the multifamily construction boom that peaked in 2024, when more than 600,000 new units were delivered nationally — the most in a single year since 1986 — is finally being absorbed 7. Vacancies, which had climbed for years as that supply hit the market, appear to have crested. Apartment List's vacancy index peaked at 7.3% in February and has since eased to 7.1%, the first decline in that measure since late 2021 37. Apartments.com likewise attributes August's milder-than-usual seasonal dip — smaller than the pullbacks seen in August 2024 and August 2025 — to improving, though still supply-constrained, pricing conditions 16.

Even so, neither source describes a tight market. Apartment List notes that units are taking an average of 32 days to lease, the longest August figure since it began tracking in 2019, a sign that landlords still have to work to fill vacancies even as pricing power creeps back 7.

Where the growth is concentrated

Across both datasets, the geography of the recovery is strikingly consistent. The Pacific Coast and parts of the Midwest and Northeast are pulling national growth figures up, while Sun Belt and Mountain West markets — the same regions that absorbed the heaviest apartment construction in recent years — are still seeing rents fall.

Apartments.com found the Pacific and Midwest regions each posting 2.2% annual rent growth, with the Northeast at 2.0%, while the South and Mountain regions logged annual declines of -0.1% and -0.5%, respectively, even as those declines narrowed over the summer 16. At the metro level, San Francisco stood out with 11.9% annual growth, followed by San Jose at 7.7%, Norfolk at 5.8% and East Bay at 5.1% 6. Meanwhile, San Antonio, Denver, Phoenix, Houston and Las Vegas all posted annual declines between 1.2% and 2.2%, reflecting markets where new supply still outpaces demand 6.

Apartment List's numbers tell nearly the same regional story with even sharper contrasts. It puts San Francisco's annual rent growth at roughly 11%, San Jose's at 7.9%, and notes that within the city of San Francisco itself, rents are up 26% year-over-year — a surge it links to the concentration of high-paying technology jobs fueling demand 7. On the other end, San Antonio's rents are down 5.1% annually, the steepest decline among large metros, while Austin — long the poster child for oversupply — has seen its year-over-year decline moderate to -2.9%, down from -6.8% a year earlier 7. Midwest cities including Milwaukee, Chicago and Minneapolis also show up as steady gainers in Apartment List's data, benefiting from relative affordability 7.

That Midwest strength shows up elsewhere in the coverage too. Reporting on Milwaukee describes rents climbing across the city to the point that renters are trading down to smaller units to keep budgets in check 4, while a look at a new downtown Allentown, Pennsylvania development — with studios starting near $1,290 a month and two-bedrooms reaching roughly $2,015 — illustrates how new construction pricing plays out at the project level even amid a national supply glut 5. Separately, research out of Hawaii examined a different angle entirely: a University of Hawaii Economic Research Organization (UHERO) study found that rising rents have limited the reach of a federal housing voucher program in the state, even though the program has been shown to support upward economic mobility for the families it does serve 2.

Where the reporting agrees

Across every outlet touching the national numbers, several points are consistent and worth taking at face value. Monthly rent growth in the broad national aggregate is essentially flat to slightly negative as of August 2026, following an unusually long stretch of monthly gains 1367. Annual rent growth, by contrast, is improving — a trend that both Apartments.com and Apartment List describe as a genuine, if gradual, inflection point rather than a blip 367. There is also broad agreement that the driver behind the softening-then-firming cycle is supply: an unprecedented apartment construction boom pushed vacancies up and rents down for roughly four years, and that boom is now winding down, allowing absorption to catch up 367. Finally, every source that breaks out geography agrees on the same basic map: Sun Belt and Mountain West metros, especially Texas and Colorado cities, remain the weak spots, while the Bay Area and Midwest are the strongest performers 1467.

Where it doesn't

The clearest divergence is in the headline monthly direction itself. Apartments.com reports rents falling -0.03% in August, ending eight months of increases 16, while Apartment List reports rents rising 0.1%, extending a streak to seven months 7 — and CNBC's framing follows Apartment List's more optimistic read, describing rents as "finally turning positive" 3. These aren't reconcilable as the same fact reported differently; they are two different indices, built on different data (average vs. median, repeat-transaction leased units vs. broader marketplace listings), arriving at opposite monthly signs in the same month. Neither figure is wrong, but readers encountering only one headline would come away with opposite impressions of where the market just moved.

There's also a difference in emphasis rather than fact: Commercial Observer's framing centers on the record streak ending while still noting the Pacific Northwest and Midwest continued climbing 1, whereas the underlying Apartments.com report itself frames the story more cautiously, as a slight monthly pullback within a broader annual improvement, without treating the streak's end as the central news 6. And the Hawaii voucher research and the Allentown building story sit outside the national rent-index debate entirely — they're locally specific data points (a program-design finding and a single new building's pricing) that neither confirm nor complicate the national trend, though they do illustrate how the same national forces play out unevenly on the ground 25.

The reading the evidence supports

Taken together, the sources support a narrow but clear conclusion: the national apartment market is not undergoing a fresh rent collapse, and it is not returning to a hot, landlord-favorable market either. It is a market where an enormous supply wave is being slowly absorbed, vacancies are inching down for the first time in years, and annual rent growth is accelerating even when monthly figures wobble near zero. The disagreement over whether August itself was up or down is a function of methodology, not a substantive dispute about market direction — and both trackers, plus CNBC's interpretation of them, converge on the same underlying trajectory. The more consequential and better-supported story is the regional one: rents are rising fastest in supply-constrained, high-demand markets like San Francisco and San Jose, and are still falling in the Sun Belt and Mountain West cities that absorbed the bulk of the construction boom. That divide, not the single-month sign flip, is what will determine how renters and landlords experience the next year of the market.
