Are you planning to rent a house? Your landlord is probably going to ask you to pay a deposit, to cover the cost in case of any damage to the property.
When you subscribe to our Startin' Student offering, BGL BNP Paribas offers a rental guarantee for 18-29 year olds and will stand guarantor in the name of the tenant for a property in Luxembourg. So you have no need to set this amount aside yourself.
