I'd have to disagree with you on this one.
Wasting 2Mbht on a house in someone else's name in a country you have no right to live as an old guy with less than 20 years to live probably isn't the best financial decision for me to make.
I din't mind giving her 300kbht, I can afford that much of a loss.
Better for a Thai bank to take the risk on the other 1M7 on my house IMHO.
If I get chucked out (been in it 8 years now), I no longer need to pay the 9k/month mortgage repayments.
