you need to get your account tagged and it must be Bangkok Bank or Kasikorn by chat or email with Wise. Then I beleive all the options listed will most likely result in international transfer.
no, it is now possible to use one of the other given options to get the desired notation. I used personal expenses and others have reported that other works as well.
yes you can on line as long as the house owner supplies the documents required to register the property. My landlady did and I registered in her name but with log in details I know so I can do it myself whenever required. She us quite happy with that as she no longer gets pestered by me to do it 2 or 3 times a month!
