A great suggestion, which I enacted about 15 years ago.
I looked at a lot of economic data from back home and in Thailand, including currency exchange rates, dating back 40-50 years. All looked promising, but .... since coming here bank interest rates in Australia reached near record lows as did currency exchange rates - ok, not so good on the money front.
Then Thai immigration changed visa requirements ... which was somewhat unexpected, but was worked around.
Now we have the Thai tax changes ... I knew the then Thai personal tax requirements before I came for a long visit to Thailand. Confirmed what I had learnt from chatting with a few Thai tax professionals here. Set up a couple of accounts back home and here to help minimise my Thai tax burden. But, tax policies change over time in most countries, and Thailand is no exception.
Do your research, plan ahead, and have Plan/Option B, C, D, .... in case the original plan become untenable.
