I have had gites in France and houses in Thailand. In Thailand it would be resort. Don't think of doing anything like it until you have lived here a while. If a resort is a dream, buy one or make one, but rent first for at least a year. You could think of homestay, but rent first. Rent first rent first. Thailand is as varied by region as France is. Get to know it first. Otherwise you can make a big mistake, like all the Brits who relocated to dying medical deserts in the Creuse and vienne
They see certainty in pensions. Everything else is to a degree less certain. They are not doing it to facilitate entry, more akin to hoops to jump through. You might be a saint with an unblemished record, but statistically you are a less safe bet than a guy who stayed in their job for 50 yrs and has a private pension and a state pension. My money comes from all over the place and by circuitous routes, but I also have 2 pensions so no probem. But Thailand is not there to make it easy. For all 'Big Joke' knows you coud be the number one assassin of the most feared hells angels. Lets face it, he's not worrying about the other example I quoted.
