For twenty years there has been an oversupply of property, with only a few smart and devious developers making money. Property prices of condos are vastly overpriced. I can't see that changing much, with or without the Chinese input.

developers are mainly betting on the AEC integration as the borders will be more lax and they expect more foreigners from neighboring countries to live in Thailand. I think people are still underestimating the number of buyers, there are a lot of high income folks in Thailand who are buying condos for everyone of their adolescent children, you can say its a trend. 1.) Its for investment 2.) kids nowadays are adapted to western lifestyles, they want to live away from home.

There is also a boom in kids in 20s-30s starting their own businesses and buying their own condos through mortgages. Not only that, there are some affordable condos for middle income folks who can finally own a decent living space also.
