The Devil Is Next Door to Me

I checked into a haunted apartment on the cheap and ended up accidentally buying the entire building. I suddenly became a tenant but could not receive the rent. What is the cause of death of the evil ghost in the haunted house? How do I attract tenants? How do I break the situation? (This is the first time for a useless college student to write a novel.

I am very grateful)
