According to Bangkok Post reporting on estimates from K-Research, Thailand had 590,000 unsold residential units across the country in the first quarter of 2026, marking a 7.2% increase from the same period a year earlier. The same reporting chain put second-hand residential listings for the quarter at 240,000 units, a 34.2% year-on-year rise that stood out against the broader inventory trend.
The reported 34.2% growth in second-hand listings was materially higher than the 7.2% increase in total unsold residential stock, meaning the resale-listing segment expanded faster than overall unsold inventory in that three-month window. Listings represent offers to sell rather than completed transactions, so the comparison does not establish a causal link between the two trends or show how the segments may interact later.
A separate Bangkok Post report, citing analyst-mediated figures, found that second-hand homes accounted for 67% of all residential transfers measured by unit count and 48% measured by total value in Q1 2026. These transfer-share numbers are reported through that analysis chain, not as a recovered direct, unfiltered table from an official government or regulatory body.
For the full year, Bangkok Post reported a K-Research outlook that nationwide unsold residential units would exceed 610,000 in 2026. This is a forward-looking outlook rather than an observed full-year result, and it does not show that the actual year-end total will match it.
The available reporting leaves key questions unanswered: it does not explain why second-hand listings grew faster than total unsold stock, or provide prices, quality, geographic distribution, or buyer and seller motivations behind the inventory build-up and transfer mix. The figures do show a short-term difference between resale-listing and total-unsold-inventory growth, alongside a large resale share of transfer activity; they do not by themselves confirm a permanent or structural change in the relationship between Thailand’s new-home and resale markets.
