Possible impediments: AirBnb and all short-term rentals illegal in Thailand unless you can get a hotel license. Foreigners cannot own land in Thailand (some exceptions exist). I won't even get into the rampant graft and corruption, and constantly changing immigration and land use laws. Thailand does have lots of wealthy Thais, not so many wealthy foreigners.<p>Maybe you mean a billionaire in Thai baht, just over $29 million USD.<p>I live in Thailand.
