Condominium freehold
Foreigners may own a condo unit in their own name — 100% legal freehold — within the building’s foreign quota.
Foreign quota (49%)
Foreigners may own no more than 49% of total sellable area in that condominium building; the other 51% must be held by Thai nationals or Thai entities.
FET — proof of funds
Purchase funds must be transferred from abroad into Thailand. Your bank issues a Foreign Exchange Transaction (FET) certificate for the Land Department transfer.
