there is no such status as property owner. As a former sales and marketing director for various property developments in Phuket for 13 years I sold many properties to customers who bought them as tourists and remained as tourists and enjoyed their properties as tourists. But that was back in the day when you could walk into any bank and immediately open an account on a tourist visa with only a passport and some proof of address.
Alan what if a tourist comes here and decides to buy a property. Then they will need a bank account. I have known many such people including myself, but when I opened my accounts 20 years ago it was easy.
