Can I own 100 % of a condominium in Thailand ?

Buying a condominium in Thailand is perhaps the simplest and easiest option available to foreigners.
The only restrictions on purchasing a condominium in Thailand, are that the percentage of units sold to foreigners cannot exceed forty nine percent (49%) of the total number of units in the condominium block; and that the funds used to buy the condominium have been remitted from abroad and correctly recorded as such by a Thai bank on a "Foreign Exchange Transaction Form".

A Foreign Exchange Transaction Form

This is an official bank document issued by the receiving bank upon the receipt of foreign currency into your bank account in Thailand. You must request a “Foreign Exchange Transaction Form” from your bank when you are remitting funds to Thailand for the purpose of purchasing a condominium in Thailand, and the “Foreign Exchange Transaction Form” must specify that the remittance is solely for the purpose of purchasing a property in Thailand - Code 5.22.

Purchases of condominiums in Thailand by foreign individuals come under the jurisdiction of the “Condominium Act B.E. 2535 (1992)”.
