Oh! You wanna move to Thailand. I heard that several expats are moving out of Chiengmai, after years of residence, to either Vietnam or Cambodia. It’s the hassle in getting a visa. So, you should really talk to people who have been here for several years.
I have met some westerners having to renew their entry visas every six months by going to Laos for the weekend. Because they are on a tourist visa.
As an ‘investor’, buy a condo here or open a company, you’ll be in a much better position.
But, this is a much safer place to be, in case of a global melt down or the severe impact of the Little Ice Age cycle for which most people have been prevented to learn about and prepare for accordingly.
Good luck.
