Trying to sell the house? In this economy? No way! The ghosts that have been haunting Elena these past months have been nothing but chill so she honestly doesn't see the need to pay for an exorcism or go through all the toubles of selling her house. At this point, they're all homies. They allow her to talk about things she can't bring up with everyone and to reflect on her playing style and career. Moreover, with her family all living in Europe, she's just glad for the company. These ghosts like to binge-watch shows and watch movies as much as any living friend you might have and they're just not bothering anybody. Of course she can't talk about them to anybody because she's gonna look like a friendless loser and/or a lunatic but that's a minor problem when you think of all the upsides of having ghosts who can't leave your house live with you.
