Information for rentersFrom what I can judge between a professional broker and a rudimentary broker?

Apart from his knowledge of the peculiarities of the Greek reality, a professional broker must also have expertise in the market, property taxation, and basic legal and planning provisions. The office should visibly display a valid Estate Agent license and a certificate from the Chamber of Commerce.

You should also ask if the broker is a member of an official Association, as this signifies approval and credibility. If they try to justify or avoid the issue, you can contact the Chamber, provide their name, and verify for yourself whether they are a legitimate professional or not.
