Can I pay for the property in Greece via a transfer from a European bank?

Yes. The transfer can be made from a foreign currency account. However, there may be a slight delay as the transfer takes around three days. It’s advisable to transfer funds a few days before the property transfer deed, where the seller will confirm receipt of the total amount. It can also be done during the deed, though this would be a conditional deed. The most prudent approach is an immediate transfer after agreeing on the transfer type with the seller.
