Controversial Olympian Marion Jones Moving Up In The World

In case you didn't already know ... in 2007 Marion -- who was considered a LEGEND in Track & Field -- copped to using steroids throughout her career and as a result was stripped of her medals, lucrative endorsement deals, and thrown in jail on charges of perjury.

But all that's behind her ... Marion and her husband just sold their modest 2,173-square-foot home ... and traded up to a much nicer 3,156-square-foot pad with 4 bedrooms and 2.5 baths ... all for a cool $212k.
