Ivana Trump -- Suck It, Donald -- I Sold My Home For $12M Profit!

Donald Trump has nothing on his ex-wife when it comes to wheeling and dealing ... because she recently sold her swanky Palm Beach estate, and made a $12 million PROFIT on the deal!

Ivana Trump bought the 12,352 sq. ft. mansion back in 1994 ... 2 years after she and DT divorced. The price tag then -- a measly $4.4M.

Ivana originally listed it for $18.9M, but dropped the price when she got no takers. Poor thing had to settle for closing the deal at $16.6 million.

The pad is called Concha Marina -- 'cause really rich folk name their houses -- and has 5 bedrooms and 7.5 bathrooms. It also features an underground tunnel to the beach.
