*Could “Neon” Deion Sanders be dealing with funny money issues and is trying desperately to sell the family mega-mansion in Prosper, Texas?

“Sanders and wife Pilar (pictured) have listed their 29,122-square-foot house for $21 million. He’s held it at that price since placing the 13-bathroom mansion on the market in 2009, according to the listing at Realtor.com.

The problem is that an appraisal of the house said it is only worth $5.6 million, roughly a quarter of the amount Sanders is asking, reports the International Business Times.

In case you’re wondering, here are some of the amenities included with the Mediterranean-style house:

o The house sits on 109 acres, and features a football field;
o It also has an indoor basketball court and a bowling alley;
o 13 bathrooms;
o a 12-acre lake;
o nine covered parking spaces;
o five fireplaces;
o three dining rooms;
o two indoor pools.

The Sanders' sprawling mega-mansion

Also helping to fuel the talk of Sanders’ money being funny is the fact that he’s also selling his Dallas penthouse for $7 million.

As an athlete, Sanders played cornerback for several teams after playing his college football at Florida State.

In the NFL, Sanders played for the Atlanta Falcons (1989-1993); San Francisco 49ers (1994); Dallas Cowboys (1995-1999); Washington Redskins (2000); and Baltimore Ravens (2004-2005). He won the Super Bowl while with the 49ers and Cowboys.

As a Major League Baseball player, Sanders played for the New York Yankees (1989-1990); Atlanta Braves (1991-1994); Cincinnati Reds (1994-1995, 1997, 2001); and San Francisco Giants (1995).

Sanders, who was inducted this month into the Pro Football Hall of Fame, works as an analyst for the NFL Network.

Despite his mega-talent as a sporting figure, Sanders has had other questionable money dealings. In 2000, he received a $56 million contract with the Washington Redskins but only stayed with the team for one season.

And he left a CBS network’s pregame show after two years in a contract dispute, according to Yahoo.
