If you plan to rent but you do not have the financial means to obtain a rent payment guarantee, you can turn to an assistance programme established by the state of Luxembourg specifically for this purpose:

Rent Payment Guarantee Assistance Programme (“Aide au Financement de la Garantie locative”)

To apply, contact the Central Housing assistance office (“Guichet unique des aides au lodgement”) of the Ministry for the Middle Classes, Tourism and Housing. Once you have been granted ministerial authorisation, contact your Spuerkeess branch.
