Foreigners can not get a mortgage loan from local banks in Thailand to buy property, unless they have a Thai partner willing to act as guarantor. There are numerous other conditions too, so if you wish to go this route, make sure you have a totally reliable Thai partner, and you have plenty of demonstrated income (either here in Thailand, or from overseas). The purchase money must be transferred from banks outside Thailand , in foreign currency form. The buyer must state that the purpose for the money transferred is to purchase a condominium unit in Thailand on the funds transfer document. The Bank is then able to issue the form of TT3 (Thor Tor 3) or Authority to Purchase for the relevant land office in Thailand , giving the foreign buyer authority to purchase.
