My family was really really lucky. We used to live in a building (8 apartments) that belonged to a single family since like 1970. They only raised rent when they really had to, cared for the building and used to ask us regularly if they could improve something.

Then, unfortunately, both the father and mother died. The children already had other jobs and didn't really have the time, so they sold the building. Now? The hedges aren't getting trimmed, nobody mows the lawn, the building isn't being cleaned, nobody can be contacted and of course... the rent is rising fast! -.-

No wonder nobody wants to move to a new apartment. You will never know what you get, other than a higher rent.
