Depends on the amount your sending. Break even point with my credit union is about ฿150k. Below that wise is cheaper. But you'll have to do your own calcs. Good luck getting your bank to quote you a rate. Probably just ask what it was the day before.
Rent don't buy. Come on 60 day exempt to look around. If you're moving within a few months, best to sign your lease during low season. Then rerun home and apply for a non-o visa from your home country.
