Vermilion waterfront mansion on the market for $19.5 million

For a mere $19.5 million you can pick up 160 acres of lakefront property. As reported by The Plain Dealer, the Vermilion mansion was home to inventor Donald Brown and his wife, Shirley, who died in a plane crash last year. Brown was best known for inventing the drop ceiling. Ironically, Waterwood Estate, as it is called, has only one drop ceiling. Perhaps a case of being sick of seeing your own creation.

Waterwood Estate features several rotating floors, two indoor pools, a private marina and a helicopter landing pad - helicopter sold separately, of course.

This beauty won't last long, I'm guessing. There's a billionaire out there somewhere right now telling his aide to get on the phone with the realtor and start negotiating. After all, it is a buyers market.
