Somewhat related but not really, The Woolworth mansion in Scranton,PA is also on the market, for $295,000. Of course in the background you can see what might be some not so nice apartments. Closer to my price range than Fiddy's place.
Just put the cooking equipment in the basement, an express lane from the projects next door and a commercial refrigeration unit in the garage to dump anyone that OD's. Cha ching.
