Fantasia Barrino -- Taking $500,000 Hit After Foreclosure Nightmare

Fantasia Barrino's finally putting her financially turbulent past behind her -- dumping the giant house in North Carolina she nearly lost to foreclosure in 2009 ... but the therapeutic real estate move is costing her nearly $500K.

Fantasia has listed the 5-bedroom, 38,768 sq. ft. mansion in Charlotte for $800,000 -- nearly $500,000 less than what she paid for it in 2007 ... $1.3 million -- and you can bet she won't get her asking price.

As we previously reported, the home isn't without its bad memories -- Fantasia nearly lost the place at public auction after allegedly defaulting on a $58,000 loan. She managed to save it at the last minute.
