Nicolas Cage has reportedly sold his Los Angeles mansion.

The 'National Treasure' actor, who owes $6 million in unpaid taxes, has sold the Bel Air property for an amount estimated to be between $9.5 and $15 million.

Cage, 45, originally asked for $35 million for the house, which he bought for almost $6.5 million in 1998.

Cage has lost a significant amount on the property market. His 11th-century Bavarian castle sold for $2.5 million, almost $150,000 less than he paid for it.

His $7.85 million Somerset castle is on the market for $5.8 million. And his $6.2 million Bath Regency townhouse, bought in 2007, was sold in March for $5.8 million.

The actor, whom Forbes estimates earned $40 million between June 2008 and June 2009, is also being sued for almost $2 million over missed credit payments.

Last week, Cage filed a lawsuit against his former business manager. The actor is suing Samuel Levin and his firm for $20 million, alleging that Levin put him in a "precarious" financial situation by making bad investments.

Cage claims Levin gave him bad advice, failed to pay taxes when they were due and claimed vast fees.
