You should only sign a new rental agreement once your case worker has given you confirmation that your move will be approved. You will only receive confirmation if you provide a valid reason for the move and have found a new, suitable apartment.
Please note: Even if you are in the so-called waiting period, we can only grant approval for relocation if the accommodation costs are reasonable.
The rule that the actual costs of accommodation are covered during the waiting period, even if these are unreasonable, only applies to apartments that were already occupied before the application was submitted (existing apartments).
