1. $140 million: Undisclosed address – Greenwich, Connecticut

Coming in at No. 1 is this massive Connecticut estate well-known for its exorbitant price tag. The listing hit the market earlier this year at $190 million, making it the most expensive listing ever, but it has since suffered a price cut of $50 million. Nonetheless, the estate is still one of the priciest homes in America and is still on the market, waiting for someone willing to buy the 12-bedroom, nine-bath 13,529-square-foot home. The property sites on a 50-acre estate with 4,000 feet of coveted waterfront facing the Long Island Sound.
