Condo ownership : Foreigners can own condos in their own name without any restrictions. However only 49 % of the units / space in a building can be owned by foreigner. So, if you buy a condo in building, where that percentage is less you can buy and own your condo 100 % in your name. Or if the seller owns in a foreign name you can own it in your name as well, because the transfer will obviously not affect the percentage of foreign ownership in a building.
Condos in Thai ownership are often around 20 - 30 % cheaper, but as a foreigner you can only own them in a company's name.
Condos Maintenance Fee : These fees in Pattaya and Jomtien are different from one building to the other. It starts as low as 13 Baht per sqm per month up to around 65 Baht. Quite often these fees have to be paid one year in advance.
Transfer : For the transfer of ownership at the land office you need a document from a bank in Thailand, which confirms, that you have send the funds in foreign currency to a bank account in Thailand. This document, called Thor Thor Sam is issued on request by the receiving bank for a fee of app. 500 Baht normally within 24 hours. If you want to buy a condo do not send the funds in Thai Baht, because then you are not entitled to get that document.
Further on at the land office the buyer needs only his passport or he can sign a power of attorney for a lawyer and give him copies of his passport and entry stamp (with a signature on each copy).
The transfer at Pattaya Land Office is done within one day, normally only a few hours and then the new owner gets his Title deed (called Chanott) immediately.
