Hi there. When I had to put 3 months deposit, I took a loan from my employer, and they took the money back of my salary for the next 3 months, I'm told this is not unusual. Also don't forget that you may not get your deposit back for another year!!! after you leave your flat, the flat contract says so. I was able to get my deposit back from Basel after leaving the flat 4 months, but ONLY because there were HIGH influences pushing my old landlord for.
