If you have decided to buy real estate in Turkey, opening an account in a local bank is quite useful for easier making and receiving transfers, as well as for paying bills for the purchased apartment, etc. You can also get a debit card to pay for goods or withdraw cash. In most Turkish banks, accounts can be opened in 4 currencies: lira, dollars, euros or pounds sterling.
As for the documents, the requirements are not too complicated. One needs to provide:
a document confirming one's residential address;
a Turkish tax identification number.
