Bruce Willis Selling MASSIVE Bev Hills Mansion -- Got $22 Million?

Bruce Willis is shaking down his real estate portfolio again ... now he's listing his biggest crib, a Spanish-style estate in Beverly Hills ... for $22 million.

The "Die Hard" star bought the 11-bedroom, 11 bathroom property in June 2004 for $9 million ... not a bad return if he gets his asking price.

Built in 1928, the 10,379 sq ft spread is spittin' distance from the Beverly Hills Hotel and has a tennis court, pool, stone fountain, arched glass doors ... standard filthy rich movie-star guy stuff.

Willis has always liked to play property chess ... and right now he's got 2 places in NYC, including a Central Park West pad he bought in March for $8.85 million, and another in the Trump Place that he listed in February for $11.65 million ... no word on a sale yet.

He also has a 2,900 sq ft ranch-style home off Mulholland Drive. 

Question is, if he finds a buyer for the big house ... is he looking for a bigger one -- or downsizing?
