In the past five years, rents in Berlin have risen by more than 40%. To give you a rough orientation:
There are currently very few offers available. Therefore, we strongly recommend that you deal with accommodations in a timely manner and that you also consider accommodation in the surroundings of Potsdam.
If you rent an apartment or a room, you must pay a rental deposit to your landlord. A deposit typically amounts to between two and three months' rent.
Caution! Do not transfer any money for a deposit etc. if you have not yet signed a contract or have not yet seen the apartment. This applies particularly to money transfers abroad. There are currently scammers on the market who want to make money from unaware apartment-seekers. If you have any doubts, please contact the Welcome Center Potsdam.
For stays of more than 3 months, you have to register with the local authorities. For the registration, you need a form called "Wohnungsgeberbestaetigung" that has to be completed and signed by your landlord.
