Landowners are putting idle land up for sale or long-term lease because the land and building tax on vacant land held over 3 years doubles in 2026, from 3,000 baht to 9,000 baht per million baht of value. Property sales are slow, so owners are willing to lease. The article says this is a chance for convenience stores and fuel-station operators seeking sites on main roads near communities, with lease examples on Rama 2, Kalpapruek, Ratchapruek and Kanchanaphisek roads. Bangchak's 10-rai, 20-year lease in Bang Yai is a case in point, with a fuel station under construction and a commercial area to open in early 2027. If you need a site, this is a negotiating window; if you lease out land, check your holding period against the tax rule.
