Dwight Schar’s company, NVR, is one of the largest residential builders in the country, having constructed more than 300,000 custom homes up and down the East Coast. So it’s not surprising he would own a few impressive places himself.

Called Windfalls, his six-bedroom, ten-bath gated mansion sits on seven acres next door to Steve Case’s Merrywood (number 2) and overlooks the Potomac River. But it pales in comparison with Schar’s beachside villa in Palm Beach, Florida, which he bought for $70 million from business magnate Ron Perelman in 2004. The 33,000-square-foot Florida estate has a movie theater, swimming pool and pool house, gym, boat dock, and walk-in humidor. At the time of purchase, the price was said to be the highest ever paid for a house in the United States.

A buddy of Dan Snyder, Schar is part owner of the Washington Redskins.
