Wanna live like a top NFL pick?? Mario Williams' one-of-a-kind Houston mansion just hit the market ... and it's got an $8.5 MILLION price tag!!
The former Houston Texans superstar is letting go of the 12,900+ square-foot crib he bought right after going #1 overall in the 2006 NFL Draft ... and it's completely tricked out!!
The pad -- which sits on 1.42 acres -- comes with 5 bedrooms, 5 1/2 bathrooms, an all-marble kitchen, 5 fireplaces and a 9-car garage.
Of course, Texas can get HOT ... but there are plenty of ways to cool off in the luxurious backyard, where there's a fancy pool with a dope waterfall, a jacuzzi and tons of space for some BBQs.
