August 2026 Rental Concessions: Read the Share

August 2026 rental concessions were advertised on an average of 43.5% of covered listings on Realtor.com across the 50 largest metros, up 3.1 percentage points from 40.4% a year earlier, according to Realtor.com’s September 17 report. The share shows how common advertised incentives were. It cannot establish their dollar value or why landlords offered them.

For operators, the increase warrants a closer look at competing offers before setting leasing assumptions. It is not a percentage to deduct from projected rent.

The covered inventory consists of listings advertised on Realtor.com for studios and one- and two-bedroom rentals, including apartments, condos, townhomes and single-family homes, across the 50 largest metropolitan areas. These are bedroom categories, not building-size categories, and the observations are listings rather than the entire rental stock. Realtor.com’s methodology defines that scope.

A concession share answers a yes-or-no question about advertising. It does not establish what renters ultimately received in signed leases. Nor does an advertisement without an incentive establish that the landlord would refuse one in negotiation.

Consider a hypothetical comparison: one listing offers a $100 fee waiver and another offers a $1,500 rent credit. Both advertise a concession, although the amounts differ substantially. Counting offers alone cannot distinguish their value. An unchanged concession share could also conceal larger or smaller incentives among listings already offering them.

Keep that distinction when comparing this release with other rental data and reports: the frequency of an offer and its economic cost need separate measures.

Geography adds another limit to the aggregate. Realtor.com’s metro table reported substantial variation in August concession shares:

Use the metro result as a starting point, then narrow the comparison to rentals that could plausibly attract the same tenant. Match bedroom count, location, condition, amenities and move-in timing. A metropolitan average cannot show whether the nearest comparable building offers an incentive on the floor plan competing with a particular vacancy.

The release also includes a measure with a different denominator and observation period. Realtor.com found that 5.1% of institutionally managed rental communities offered concessions continuously over the preceding 12 months. That measures the persistence of offers at the community level, distinct from the monthly listing share. The report describes both measures.

Subtracting one percentage from the other would not reveal the share of temporary offers. Continuous advertising also cannot, by itself, distinguish a standing pricing policy from continuing difficulty filling units.

The linked Avail landlord concession survey introduces a third population. Avail’s September 11 publication describes a June 2026 survey of 408 verified platform landlords, 90.2% of whom managed fewer than 20 units. Its separate platform analysis covers marketplace activity through the second quarter.

The unit being counted matters. In a hypothetical survey, an owner with one available rental and an owner with ten could each contribute one response. Those responses would count owners, not their available homes. A survey question restricted to landlords already offering concessions would have a narrower respondent denominator still.

Averaging a landlord-response percentage with a listing share would therefore not produce a valid estimate for all rentals. Pooling the two would require a defined common population, compatible dates and defensible weights. These releases do not provide that basis. Treat survey responses as evidence about respondents’ stated decisions; they do not establish motives for the August listings.

For an operating review, build a dated record of direct competitors that keeps three questions separate:

1. How prevalent are offers? Record the number of comparable listings checked and the number advertising incentives. Keep selection rules consistent between reviews, and log additions and removals so changes in the sample are visible.
2. What is actually available? Record the eligible unit, incentive amount or benefit, required lease term, move-in deadline and other conditions. Mark an offer as unconfirmed until its applicability is checked.
3. Is your leasing performance weakening? Compare those observations with your own inquiries, tours, applications and days vacant. Keep competing advertisements separate from concessions actually granted in your leases.

This proposed monitoring method does not reconstruct Realtor.com’s methodology. It makes changes in rental operating assumptions traceable to relevant evidence.

If comparable offers become more widespread while your own leasing response weakens, test a more generous incentive allowance or a longer vacancy period in the budget. If incentives remain concentrated in properties outside your competitive set, record that limitation before changing assumptions. Base the decision on offers tenants can use and leasing results you observe; an advertisement alone cannot diagnose a competitor’s finances.
