When looking for a place to live, it is very important that you make sure that you do not fall into the hands of frauds. Be careful by making sure that you have seen the flat before you paying a commission or receiving the key. Do not sign the contract unless you are sure that the contract is serious, if not sure, ask friends and acquaintances.
If you have paid a commission and this is on the rental agreement, the Jobcenter will then contact you and it could be that they will no longer cover your costs (because it would **** like that you have enough money available).
