Location: Tucson, Ariz.
The Skinny: Located on the edge of the 20 million acre Coronado National Forest, this 24-room glass-and-stone mansion looks like it might be home to some villainous characters. After all, what law-abiding citizen would construct such an enormous and dramatic personal residence? More importantly, who would purchase such a home? Well, apparently, no one. The place has been on the market for more than six years without a buyer, and is now listed for $15.9M, down from a high of $22M back in 2007. If a buyer does materialize, they'll be getting plenty for their money: 25,000-square-feet of interiors, 6,000-square-feet of balconies and patios, seven bedrooms, 11 baths, a swimming pool, spa, tennis court, gym, and, most villainous of all, an indoor shooting range.
