Co-ownership in property acquisition is allowed, provided that the amount invested by each joint owner is €250.000. In cases of joint ownership of the real estate property by spouses or partners under a cohabitation agreement concluded in Greece, the above condition is not applied and the residence right is granted to both, with a signed contract of 250.000 euros.
So only if you are married or conclude a cohabitation agreement in Greece can you both be granted the permanent residence permit under the amount of 250.000 euros in total.
