"ER" stud Eriq La Salle has conquered TV ... TV movies ... films ... books and now, he's conquered real-estate -- unloading his Beverly Hills mansion for $4.3 MILLION MORE than he paid.
La Salle -- best known as Dr. Peter Benton on that show that launched George Clooney -- bought the casa way back in 1988 for a mere $1.7 million. He sold it this month for $6 MILLION!!!!
Our real-estate sources tell us ... Eriq chose to sell now, because he's looking to downsize.
The Tuscan-inspired villa is worth every penny ... 6,000 square feet, 4 bedrooms, 5.5 baths, pool, spa, roof top deck, wine cellar, weight room, panoramic views of LA ... not to mention Eriq had the place redone in 2006, so everything is in tip-top shape.
FUN FACT: 1988 is the same year Eriq's fist major movie -- "Coming to America" with Eddie Murphy -- hit theaters. Soul Glo, bitches ...
