Buying property and residency

You don't need to own to get the residence permit. But then you need to rent, and make sure that the landlord is available to visit a notary.

It varies from one area to another but generally you  need your passport,  EHIC card and around  5_ to six hundred levs in the bank. A translator to assist you and plenty of patience.
Things may change after Brexit .

You don't have to buy anything, in order to apply for a residency. Of course you will need a solid reason and besides there are different types of residence permit, but generally EU citizens do not need it for a period shorter than 6 months.
