No problem! You must provide us with SEPA at the moment of booking. Only if you are not from a Euro country, it is possible to deliver it to us later. In any case, you must provide us with SEPA no later than 14 days after your tenancy agreement starts via our contact form.
In this case, please note that you must transfer the first month's costs at least 14 days before the start of your tenancy.
You will find the document for the SEPA mandate in your contract documents or here.
