Comfortably affording the typical U.S. rental takes $78,488 in annual income. Affording the typical mortgage payment takes nearly $99,800. Zillow published both estimates in its July rental report on August 18, and the distance between them, more than $21,000, is the company’s own explanation for why demand for rentals has not softened even after the largest apartment construction wave in decades.
The $21,000 gap keeps would-be buyers renting
Rental demand in this report is not a story about renters wanting to rent. It is a story about the alternative pricing itself out of reach. With mortgage rates holding above 6.5 percent, households that might otherwise have bought are staying put in leases, and that steady occupancy is what has kept asking rents rising even where new buildings opened.
Zillow puts the typical renter’s rent burden at about 26.8 percent of income, under the 30 percent share conventionally treated as the line for cost burden. That figure and the two income thresholds come from the company’s July rental market release, and all three rest on Zillow’s own index and its own affordability assumptions rather than on a federal survey.

What Zillow measures, and what the Census Bureau measures
The $1,962 figure is the Zillow Observed Rent Index for July, up 2.3 percent from a year earlier, which the company describes as the fastest annual pace in more than a year. It is an index of asking rents on listings, built from properties advertised on Zillow’s own platform. It is not a government statistic, and it does not describe what a household already three years into a lease is paying this month.
The federal comparison shows how much the yardstick matters. In the Census Bureau’s second-quarter 2026 residential vacancies release, published July 28, the median asking rent for vacant units offered for rent was $1,531, with a rental vacancy rate of 7.3 percent. Both numbers describe asking rents, and they differ by more than $400 because they cover different sets of properties collected in different ways. A third federal benchmark exists as well: the Department of Housing and Urban Development publishes annual Fair Market Rents area by area, the figures that set payment standards for housing vouchers. Three measures, three answers, none of them interchangeable.
The 26.8 percent national rent burden hides the same kind of spread. In Zillow’s metro table, renters in New York spend an estimated 40.9 percent of income on rent and renters in Miami 37.1 percent, while the shares in Austin and Raleigh sit at 18.7 percent and 18.4 percent. A single national income threshold is a useful headline and a poor budgeting tool, because the market a household actually rents in determines whether $78,488 is generous or insufficient.
Asking rents fell in San Antonio, Denver, Austin and Tampa
A 2.3 percent national average is the sum of metros moving in opposite directions, and the falling ones are not small. San Antonio asking rents were down 1.8 percent from a year earlier, Denver down 0.9 percent, Austin down 0.9 percent, and Tampa down 0.5 percent. Dallas and Houston were effectively flat, at 0.1 percent and 0.0 percent. Any claim that rents are climbing everywhere runs straight into those six.
The increases cluster where construction did not. San Francisco asking rents rose 9.7 percent to $3,372, San Jose rose 7 percent to $3,782, and Chicago rose 5.1 percent to $2,253. New York remains the most expensive large market in the table at $3,627, up 4.5 percent. Zillow’s own reading of the split is that markets which did not add much supply have scarce deals and fast rent growth, while the metros that built heavily are still working through the inventory.
Two in five listings still came with a concession
The counterweight to the rent number is what property managers are still giving away. In July, 39.8 percent of rentals listed on Zillow offered a concession, up from 35.9 percent a year earlier, a rise of nearly four percentage points at the same time rent growth was accelerating. The concentration follows the construction: Charlotte at 68.1 percent, Denver at 67.2 percent, and Dallas at 65.6 percent all topped two-thirds of listings.
One limit belongs with that statistic. Zillow reports the share of listings advertising a concession, not what a concession is worth, so the data support no dollar estimate of what the average renter saves. The company also expects the share to ease gradually as the market tightens, which makes the current reading closer to a peak than a trend line.
Multifamily permits are running 31 percent below their 2022 peak
The deals exist because of a building boom that is now ending. Zillow points to second-quarter multifamily permits running 31 percent below their most recent peak in 2022 as the reason the pipeline is narrowing, drawing on the permit series the Census Bureau publishes in its monthly new residential construction report. Fewer permits now means fewer competing vacancies later.
The composition of the increase already reflects that. Single-family rents rose 3 percent to $2,314, well ahead of the 1.7 percent gain for multifamily units at $1,786, a split Zillow attributes to how heavily recent construction skewed toward apartments. For the full year the company forecasts multifamily rents up about 1.9 percent and single-family rents closer to 2.9 percent, both still under the long-run historical average. “The supply tailwind is fading, rent growth is picking back up, and concession rates that have been climbing for two years are expected to start easing,” Mischa Fisher, Zillow’s chief economist, said in the release.
