Rapper Lil Wayne wants to, or maybe just needs to, unload his Miami mansion on La Gorce Island, Fla., that he purchased early last year for $14 million. He is asking $12.9 million for a possible quick sale given he has an Internal Revenue Service tax lien hanging over his head.

The IRS says the rapper, whose real name is Dwayne Michael Carter, Jr., owes the government a total of $5.6 million, which breaks down to $3,351,078 owed for 2008 and $2,258,956 for 2009. Last year, he had liens against him for more than $1 million for the tax years 2004, 2005 and 2007.

Before purchasing his 15,101-square-foot home he had rented it for several months from a real estate developer, area real estate agent Andre Shambley of the ERA Herman Group told this AOL Real Estate contributor. While renting, Lil Wayne's four-bedroom South Beach condo at the Murano Grande was on the market for $2.8 million to help pay off last year's lien. The 9-bedroom, 9 full-bath, glass, steel and marble modern residence has a two-story master suite accessible by a glass elevator and two half baths. The living room truly has a floor-to-ceiling wall of glass, which stretches the full length and height of the open space.

In addition to the 2004-built three-level estate there is also a 3-bedroom guest house, a swimming pool, a 3-car garage and about 120 feet of water frontage on Biscayne Bay.
