David Tepper's House

Tepper is the founder and head of Appaloosa Management, one of the top performing large hedge funds on Wall Street. As of March 2014, Forbes ranks him as the 122nd richest person in the world, worth an estimated $10 billion. Tepper is also a minority owner of the Pittsburgh Steelers.

He purchased this rather modest house in 1990 for $1,229,730, though he's currently building a Hamptons waterfront mega-mansion.
