The national rental vacancy rate rose to 7.6% in the third quarter of 2026, up from 7.1% a year earlier and 7.3% in the second quarter, the Census Bureau reported on Oct. 28. That is the highest quarterly reading in the bureau's own table going back to 2020. But professionally managed apartments tell a tighter story, and the gap between the two is where this quarter's leasing decisions get made.
What happened
The Census Bureau's quarterly Housing Vacancy Survey counted about 3.87 million year-round units vacant and for rent, roughly 317,000 more than a year earlier. The median asking rent on those vacant units was $1,541. The figures are not seasonally adjusted, and the national rate carries a margin of error of 0.3 percentage points.
The slack is not spread evenly:
- Principal cities vs. suburbs. Rental vacancy was 8.8% in principal cities, against 6.5% in suburbs and 6.4% outside metro areas. A year earlier, principal cities sat at 7.3%. The bureau warns that metro boundaries changed between the two periods, so treat that year-over-year comparison with caution.
- Regions. The South had the highest rate at 9.2%. The Northeast (6.2%) and West (6.7%) rose from a year earlier, while the Midwest and South were not statistically different from the third quarter of 2025.
- Ownership is flat. The homeownership rate was 65.5%, not statistically different from a year earlier, and homeowner vacancy held at 1.2%. The flat ownership rate suggests the rise in rental vacancy is not mainly renters leaving to buy.
Why it matters for property managers
Two data sets, two different pictures. RealPage's apartment data shows occupancy averaging 95.2% in September 2026, with same-store effective rents up 1.5% year over year and annual absorption of 323,106 units slightly exceeding completions of 317,966. RealPage's Q3 recap says the market "turned a corner" as the supply wave recedes.
Both can be true. As we read them, the Census survey measures the rental inventory as a whole, including single-family rentals, small buildings and older units. Apartment trackers like RealPage focus on stabilized apartment communities. If your portfolio is newer, professionally managed multifamily, the improving apartment data is probably closer to your reality. If you own scattered-site homes, small multifamily, or older stock in a principal city or the South, the Census number is a warning worth taking seriously.
Older and cheaper stock is still under pressure. RealPage reports concessions on 18.1% of Class C units in September, versus 12.5% for Class A, and its Q3 recap says Class C product remains under pressure. Census does not break out class, but its principal-city and regional numbers point the same way: the softness is concentrated, not universal.
Discounts are narrower but deep. Concessions fell to 14.5% of stabilized units in September, the lowest share since September 2025, yet the average concession was 11.1%, about 5.8 weeks free on a 12-month lease. In a market where vacant inventory grew by 317,000 units in a year, an extra month of vacancy can cost as much as a concession, so run the numbers unit by unit.
Demand risk in 2027. RealPage flags that a sharp drop in immigration could weigh on demand in 2027, alongside slipping real wage growth. That is a forecast, not a done deal, but it argues against underwriting 2027 as if demand will keep pace with this year's absorption.
What to do this week
- Benchmark your own vacancy against the right number. Compare each property's physical vacancy to the Census rate for its region and area type, and to RealPage-style occupancy for comparable apartment communities. A scattered-site home in a principal city of the South should be measured against a 9.2% regional rate, not against 95% apartment occupancy.
- Price renewals to keep good residents. With vacant inventory up year over year, a turn plus weeks of downtime can easily cost more than a smaller increase. Run the breakeven on every renewal expiring through February before sending offers.
- Target concessions instead of blanketing them. RealPage reports operators are trimming how many units carry an incentive before trimming the incentive itself; do the same by limiting incentives to units and floorplans that are actually sitting. Track days-on-market by unit and add a concession only after a set threshold.
- Tighten the turn. Every week a ready unit sits empty adds to the cost. Pre-schedule vendors for move-outs heading into the winter leasing season.
- Stress-test 2027 budgets. Model a scenario with meaningfully higher vacancy than today for Class C, small-building and single-family holdings, and see whether debt service and reserves still clear.
- Check your concession and fee practices against local rules. Advertising, fee disclosure and concession rules vary by state and city. Confirm with local counsel before changing how you market discounts.
What we're watching
- Fourth-quarter Census data, scheduled for Feb. 2, 2027. It will show whether the rise continues into winter; because the data are not seasonally adjusted, compare it with the fourth quarter of 2025 rather than with this quarter.
- Whether apartment occupancy holds above 95% as completions slow and winter leasing begins.
- Class C and small-landlord performance, where the concession and vacancy data show the most stress.
- Immigration and job data, which RealPage identifies as a 2027 demand risk.
For a portfolio, the takeaway is simple: national vacancy is rising, but it is rising unevenly. Know which data set describes your units, and price accordingly.
