thank you for your reply. I did not realise that. So I suppose a follow on question, does it cause any problems if the account is in a different province. I know that the bank charges for out of province withdrawals, but that is overcome by doing cardless withdrawals. The main concern for me is that there are no problems when it comes to the yearly extension.
I have just done the same thing in Nong Khai. The account was set up in Udon Thani. Whent into the Nong Khai branch and asked to change address on my account. No problems, and they were very helpful.
As a single guy I live on around 45,000 bht per month in Nong Khai. I enjoy the quiet life and going to local Thai bars for a few beers. Also do a bit of travelling around. It all depends on the life style you want.
