In the last season of "Million Dollar Listing" a house was sold only after the ghost was sent out. This is a beach house near LA.
"The seance forced on Madison and his seller at the Malibu house seemed far less creepy than it should've, maybe because it was conducted on the floor of a bright, sunny beachhouse in Malibu? In any case, it conveniently extricated the lingering ghost of the previous owner who had died inside the house. If you're hesitant it worked, don't worry. The psychic brought in said she had a vision of the dead man giving a thumbs up on his way out. Phew!"
