I think that everyone is missing a big point, although i have only read 4 pages , but. They are young, you think he was mortgage free, i highly doubt it so keeping the house was not an option. they can give it a try, they can home school the kids, they can learn Thai culture, the kids are more resilient then the parents, they will adapt, they both can work, 80 thousand baht to support 4 no problem, I live on a lot less and support 4 albeit only one foreigner. if in a few years its not working then go back, they are still in their forties, A lot harder if you pull stakes at 50 + oh and health insurance is also a lot cheaper mid thirties. The only thing I would question I Hua Hinn maybe for a year to climatize but there are far more reasonable places in Thailand to rent a house and food for that matter, I would be going north, my two cents worth.
