Thanks to everyone for their advice. As we are flying from Saigon, extra baggage is pretty cheap. We are probably only paying 350 dollars in excess baggage.
I can't get a Thai bank account on DTV. It is not possible. So I suspect it will be hard to assess tax liability without this. I'll just have to live off my wife
whilst there is a certain truth to what you are saying, returns can be made in Thailand. I've seen rental returns friends have made and these average out at about 5-6% after all expenses. Capital appreciation is minimal, but equally few have depreciated. I'm not saying there aren't better investment returns, but maybe Thai property isn't as bad as you suggest.
