Ever wonder what it'd be like to have a golf simulator AND an insane Kobe Bryant themed-court at home?!? For billionaire hedge fund exec Jeffrey Feinberg, that just became a reality ... 'cause the dude just bought a $44 million mansion in Los Angeles -- THAT COMES WITH BOTH!!! Feinberg just purchased the property recently, the house’s developer, Ramtin Ray Nosrati, told The Wall Street Journal -- and it's one of the most ridiculous places you'll see. There's 7 bedrooms, 11 bathrooms, it's 54,885 square feet AND it sits on over 1.2 acres of land.
