To give you an example of rent related to income: I live and work in Berlin and my rent is about 25% of my income after taxes. I have about 100 square meters, two balconies and a lift (third floor) in a quiet pre-war (Altbau) building (redeveloped 2005) with a big playground right in front of it. It's about 6km to my work (20 minutes by bicycle) in Berlin Mitte (the east center of Berlin).
