Realtor.com®'s Generational Housing Succession report, released Monday, projects that 13.9 million homes now held by older owner-occupants will be freed up from 2026 through 2036. Across that window, activity steps up, starting near 1.27 million in 2027 and reaching 1.52 million by 2036. A quick back-of-the-envelope check illustrates the effect: if 45% of the homes slated for release in 2027 were listed for sale, that by itself would push annual listing totals back to pre-pandemic norms, assuming other factors stay the same.
That is welcome news for buyers who have been boxed out by thin inventory. It does not mean the market suddenly becomes balanced or cheap. In the words of Jiayi Xu, senior economist at Realtor.com, "We believe the softness will be real, though its effects will be uneven across segments and markets, not a uniform, nationwide correction."
Here is the catch: the incoming supply does not line up neatly with where scarcity bites hardest. Only about 380,000 of the projected releases are two bedrooms or fewer. Nearly three quarters are three or four bedrooms, with millions more in the five-plus category.
Relative to today's mix, the gap is striking. Averaged per year, that amounts to about 3.2% of recent starter-home listings, versus 24.7% for family-home listings and 67.2% for large-home listings. Translation: the smallest boost lands where first-time buyers feel the most pressure, while the biggest lift hits segments that may face a tougher demand test.
Affordability compounds the mismatch. In a separate May study, Realtor.com and the National Association of Realtors® found that only 23% of listings were within reach for a household with about $75,000 in income - roughly half the share seen in a balanced market. Different yardsticks - bedroom count versus price - same takeaway: more choice only helps if it meets demand.
Competition for smaller homes may remain brisk because of older buyers, too. Using movers in the American Community Survey as a stand-in for recent buyers, Xu found that around 30% of purchasers of starter-sized homes are age 60 and above. "Around 30% of buyers of starter homes are aged 60 and above, suggesting older buyers, whether downsizers or late-life first-time buyers, may compete meaningfully with younger, first-time buyers for this segment," she says.
Demographic shifts move housing supply more slowly and more surely than rates do. Market Briefs reads the housing data free every morning.
There is a possible chain reaction that could help: more family-home inventory can make it easier for existing starter-home owners to move up, freeing those entry-level places for new buyers. Just do not bank on a quick fix. "It is important to note that this 'free-up' mechanism is a secondary channel, and it may take longer to materialize," Xu says. "The primary solution to the starter-home shortage remains more new construction."
Demand could soften even as supply loosens. Harvard's Joint Center for Housing Studies projects U.S. households will grow by 8.6 million from 2025 to 2035, a slower pace than the prior decade as aging boomers accelerate losses among older households and household formation among younger adults cools. Higher mortgage rates can narrow the buyer pool without making homes feel cheaper for those still in it. As Xu puts it, "First-time homebuyers themselves are rate-sensitive, so any net benefit from reduced competition would need to outweigh the direct cost of financing at a higher rate, which makes the mechanism unlikely to deliver a clear win in reality."
The condition of released homes matters, too. "A $700,000 home that needs $100,000 in improvement doesn't necessarily solve the affordability issue for most first-time buyers, but it does help some," says Lisa Harris, an associate at Re/Max Center in Braselton, GA.
Where these imbalances land will shape price moves. Research released in April by the National Association of Home Builders highlighted markets including Pittsburgh, Buffalo, NY, and Rochester, NY as areas where aging demographics and slower growth increase the chances that turnover will outstrip new demand. Other metros with stronger growth or more pent-up buyers may absorb the inventory older owners release. Crucially, it is not just how many homes arrive, but whether each market has enough buyers who want - and can afford - those specific homes.
In Las Vegas, agent Bob Little is already seeing those forces collide. "I don't think baby boomer turnover by itself is going to dramatically change affordability," he says. "Interest rates and overall buyer demand are still much bigger factors in our market."
From here, Xu says the tell will be whether relief higher up the ladder spreads. "What we'll be watching for instead is whether family and large homes continue to see real relief as projected, and whether that relief stays contained to those segments or eventually spill over to ease pressure on entry-level buyers as well," she says.
What does this mean for your money? Expect the shake-up to hit bigger homes first. Entry-level relief will likely hinge on new construction, mortgage rates, renovation costs, and whether your local market has the right buyers for the right homes at the right prices.
