For $300,000 on eBay, you could purchase your very own cave house. Supposedly, “this property used to be some sort of musical venue called ‘Caveland’ where the likes of Bob Seger and Ike and Tina Turner once performed.” Auction page. Click here for first picture in gallery.
Apparently the house is finished, but most of the photos show the house in an unfinished form. But whatever, because the main point here is that these people are living in a cave.
