In retrospect, it was eye opening how gullible everyone involved was (myself included), and how little the police did about it.
For every appartement I've since rented I checked the official register to make sure my future landlord actually owns the place...
Sorry for the stupid question, but what does this mean? How does one check this?
Landlord ends up no rent and new renter lost money and has no place to live. If scammer used a fake/stolen identity then it's practically impossible to do anything.
The idea is they take the sublessee's deposit and first rent payment, don't pay the owner the rent, and vanish. The sublessee has now payed deposit + rent but has nowhere to live (as the landlord is unpaid).
This happened to my relative when someone owed her $9000 in rent. We were able to retrieve most of it via small claims court. It also helped he was dumb enough to leave bank papers behind when he was evicted so it made the process easier. A credit agency is handling the rest.
