The U.S. housing market may be on the verge of a generational handoff. Realtor.com has released a new report, "Closing Time for a Generation": baby boomers and the silent generation currently own and live in 13.9 million homes, which are expected to hit the market between 2026 and 2036. But first-time buyers shouldn't celebrate just yet — most of these homes are not the affordable starter units they need.
The report's author, Realtor.com economist Jiayi Xu, estimates the 13.9 million figure is about 34 percent higher than what older households released over the past decade (3.5 million more), and 74 percent more than boomers and silents themselves released in that period (5.9 million more). The pace accelerates each year: roughly 1.27 million homes a year in 2027, rising to about 1.52 million by 2036. Around 2029, boomers will overtake the silent generation as the main source of new inventory.
The catch is the mix. Of the 13.9 million, family homes with 3 to 4 bedrooms account for 9.9 million (71.2 percent), nearly a million a year; large homes with 5 or more bedrooms add another 3.6 million, about 360,000 a year — the latter nearly two-thirds of recent large-home listings. Starter homes with 0 to 2 bedrooms, the segment first-time buyers need most, contribute only 0.38 million over the whole decade — about 38,000 a year, a mere 3.2 percent of recent starter-home listings.
Why won't the small homes come to market? Because their owners don't need the money. Nearly three-quarters of starter-home owners aged 70 to 79 have paid off their mortgages, compared with 65.1 percent of family-home owners and 58.9 percent of large-home owners. With no monthly payment pressure, there's little incentive to move. Although boomers and silents are estimated to own 1.33 million starter homes (51.3 percent of that segment), less than a third will be released within a decade.
The report lists the release channels: owners passing away, moving into assisted living, household consolidation, and conversion to rentals. This is not a fire sale — it's a slow generational turnover. The two generations' owner-occupied stock will shrink from about 36.7 million today to roughly 22.8 million by 2036.
Xu told FOX Business the direct impact on first-time buyers will be limited, but there is an indirect channel: when existing starter-home owners trade up, their smaller homes enter the market — with a lag. In other words, the big boomer homes get absorbed first by move-up buyers, and their old small homes flow downstream afterward; the full chain could take years.
For the U.S. housing market, inventory will genuinely grow over the next decade — but the mismatch means "more homes for sale" doesn't equal "more affordable homes." What first-time buyers are really waiting for may not be boomer homes, but a simultaneous retreat in both mortgage rates and prices.
