In Thailand, foreign nationals are not allowed to buy. Or didn’t used to be. You had to rent
Last I heard, you can buy a condo, just not land.
You can start a Thai Corporation and the Corporation can own land.
Just what I heard when I was there.
Being able to speak the language while not a diplomat or businessman has got me over several rough spots easily- that and when I see that a uniform has taken an interest in me I walk straight to him and address him by rank and tell him what a wonderful country it is. I wind up drinking coffee with him and/or getting our picture taken together to show his friends and family. Do learn some of the language, at least the meet-and-greets and "sorry, sir, but that is all the Thai I know. I am studying." It will be appreciated that you are trying.
