This hasn't been a very good year for Ira Rennert, the shadowy tycoon who built a fortune by scooping up steel, magnesium, coal, and lead companies around the world. Rennert reportedly lost $100-$200 million by investing his money with Bernie Madoff (although considering the new installment of the Forbes 400 lists his net worth at $4 billion, it's not like he's going to have to start panhandling anytime soon). Today, however, there's a bit of good news for Rennert: According to Zillow.com, Rennert's ridiculously massive house in the Hamptons once again takes top honors for being the largest home in the U.S. Don't believe it? A few photos of Rennert's 66,395-square-foot, 29-bed, 39-bath Italianate mansion are below.
