The US rental vacancy rate stood at 7.1 percent in the third quarter of 2025, up from 7.0 percent in the second quarter, per the Census Bureau's Housing Vacancies and Homeownership Survey released in December 2025 — and that single number is the best lens a small landlord has for reading the Q1 2026 report due out this spring. The gap between the two quarters was not statistically significant, the Census Bureau noted, which is itself information: the vacancy rate has been climbing slowly and steadily since its lows below 6 percent in 2021 and 2022. This piece is information about how to read the release, not investment advice.
TOOR NEWS publishes analysis of housing data as it lands. This guide walks through what the Housing Vacancies and Homeownership Survey measures, which lines matter for a one-to-ten-unit owner, and what changed between the 2025 releases that frame the Q1 2026 print.
What Does the Census Rental Vacancy Release Actually Measure?
The rental vacancy rate is the share of rental units that are vacant and available for rent, expressed as a percentage of all rental units — occupied plus vacant — in the survey's sample. The Housing Vacancies and Homeownership Survey, run continuously by the Census Bureau since 1956, is a household survey, not a count of listings. It covers the whole rental stock, including single-family homes, small duplexes, and apartments, unlike listing-based measures from private platforms that only capture vacant units advertised on those platforms.
That difference matters. A portal's "vacancy" figure moves with listing inventory and seasonality. The survey figure moves with the actual stock. For the nation as a whole, the third-quarter 2025 reading of 7.1 percent sat well above the 5.6-to-5.8 percent range the series touched in late 2021 and early 2022, per the series history published with the release.
Which Lines of the Report Matter Most to Small Landlords?
Four lines do most of the work. The first is the national rental vacancy rate itself — 7.1 percent in Q3 2025 — which sets the supply backdrop for rent-setting everywhere. The second is the gross rent figure the survey publishes, the median contract rent plus average utility costs, which is the cleanest public measure of what tenants actually pay across the whole stock rather than just new leases. The third is the vacancy rate by region, because a national 7.1 percent blends a tight Northeast with looser Southern markets. The fourth is the homeowner vacancy rate, which signals how much for-sale inventory might convert into rental competition.
The release also carries state and metropolitan estimates, but the Census Bureau flags small-sample volatility in them. A single metro's quarterly move is rarely significant; three or four quarters of direction is.

What Did the 2025 Readings Change?
The 2025 releases confirmed a gradual loosening. The rate was 7.0 percent in Q2 2025 and 7.1 percent in Q3 2025, per the Census Bureau, with the difference statistically indistinguishable. The series has now spent more than a year above 6.8 percent, a range last seen in the early months of 2020 and before that in 2016-2017, per the published series history.
The proximate cause is delivery volume. Builders completed roughly 608,000 multifamily units in 2024, the highest annual total since 1986, per the Census Bureau's Survey of Construction as tabulated by the National Association of Home Builders in July 2025. New units lease up as vacant inventory first, which pushes the measured vacancy rate up even where demand is steady.
How Should a Landlord Read the Q1 2026 Report When It Lands?
Three comparisons are worth making before reacting to the headline number. Compare the national rate against the prior quarter and against the same quarter a year earlier, since the series has a mild seasonal pattern. Compare the regional table against the metro's own listing trends, because the survey's regional cells are broader than any single submarket. And compare the median gross rent line against asking rents in the local market — a falling or flat gross rent alongside a stable vacancy rate tells a different story than the same rent move alongside rising vacancy.
The honest limit of the data is timing and geography. The survey says nothing about concessions, renewal increases, or neighborhood-level conditions, and its quarterly fieldwork means a release dated months after the quarter reflects leases signed well before publication.
Where Does the Vacancy Rate Fit in Rent-Setting Math?
Vacancy is a cost, and the survey's national rate is the baseline for pricing it. A property with $2,000 in monthly gross rent and 7 percent average vacancy loses about $1,680 a year before any turnover costs — an illustration using the national Q3 2025 rate as the vacancy assumption, not a forecast for any specific property. Owners in tighter markets plug in a lower rate; owners in supply-heavy Sun Belt submarkets may need a higher one.
The rate also disciplines hold periods. A unit that sits vacant for six weeks at $1,800 a month forgoes about $2,700, which is often more than the discount needed to lease it immediately — a comparison that depends entirely on local conditions the national survey does not measure.
What Should Readers Watch in the Next Release?
Watch whether the national rate holds above 7 percent for a second consecutive reading, which would mark its longest stretch at that level since 2016-2017 in the published series. Watch the Northeast-versus-South gap, which widened as 2024's record deliveries concentrated in the South and West. And watch the median gross rent line, because rent that keeps rising while vacancy rises is a signal of demand outrunning even heavy supply. The data covers the stock as a whole; it says nothing about any individual property's pricing power.
