When former Washington Wizards guard Gilbert Arenas signed a gigantic $111 million contract extension back in the summer of 2008, we sharply disagreed with the move, while giving a knowing nod to Arenas' reputation as the NBA's lovable goofball prince. Undeterred, Arenas set to spending that money and enhancing that reputation by beginning construction on a massive D.C.-area mansion complete with a grotto, an infamous shark tank (that cost $5,000 a month in maintenance bills), seven bedrooms, seven bathrooms, and a couple of "sitting rooms" that sit between bedrooms and bathrooms that Gilbert clearly didn't use much as his knees (and reputation) fell apart over the years since.

Things bottomed out in 2011-12 for Gil, as he sat on the end of the bench in Memphis, two teams away from Washington and working for a minimum salary after hitting the waiver wire in late 2011. The contract has finally run its course, Gilbert's time in the NBA is likely done, and soon after the last of that confetti was swept away, Arenas put his mansion up for sale. According to his realtors, it can be yours for $3.5 million.

Via D.C. Sports Bog, Deadspin, SB Nation and Mouse on House you can now look at the mansion that once held so much promise. So much promise of shark and bikini but mostly shark grotto parties. Click the jump for a few pictures of the one-time palace:
