Keep a second search running
A residence application is not a booking. Compare shared-flat rooms and private rentals in Aachen while you wait. Check the address, the landlord or main tenant, the total monthly cost and the contract before paying.
Before you sign
- Kaution is a refundable security deposit. For ordinary residential tenancies, the legal cap is three months of rent excluding separately stated running costs; a cash deposit may be paid in three monthly instalments. Check your contract before paying.
- Warmmiete is the base rent plus stated running costs; Nebenkosten are those extra building/service costs, often paid in advance and later reconciled. Ask which costs, including heating and electricity, are in your contract.
- Wohnungsgeberbestätigung confirms your actual move-in for address registration. The owner or main tenant signs it. It is separate from the rental contract.
- Scam warning: verify the person and the room before sending money or sensitive documents. RWTH warns about fake offers and requests for a deposit to receive keys. Its Housing Advice Service can help RWTH students check a suspicious offer.
