I have found a tenant

Once you have found a tenant, you have to remove the ad from BoligPortal. You do so by clicking "Marker lejemålet udlejet/reserveret" under “My Menu”.

Then you click "Marker lejemålet udlejet" and the ad will automatically disappear from BoligPortal and those that have contacted you regarding the ad will be notified that the rental is no longer available.
