Hi fettlers,
as far as I know you don't need to own a property to open a bank account but what you will need is a tax number, without one the banks can't open an account for you. you have to go to the tax office with your passport and register with them. i went in May while we were over and fortunately for me a Turkish friend came along with me and he knew exactly where to go and we by-passed the long queues and the whole process took less than ten minutes.
From the tax office we went to Garanti bank in Fethiye and the accounts were opened after a little bit more form filling in about 20 minutes.without my friends help we would have been all day in the tax office, never mind actually opening a bank account!
