Birdman’s unloaded his massive Miami estate, known for its super-exclusive location on Palm Island, where another famous resident once lived … Al Capone!!!

The rapper and record exec sold the nearly 20,000-sq.-ft crib — which has 7 bedrooms, 9 full bathrooms and 4 half baths — for $10.85 million. Just to give you an idea of how big it is … the master bedroom alone is more than 3,000 square feet!

The palace sits on a 30,000-sq.-ft lot in the Miami Beach gated community … which has some true gangster history. Capone spent some of his final, fragile days on Palm Island … and it’s where he died in 1947.

Birdman originally put it on the market in November 2018 at $15.5 mil. It went through 2 realtors before it was finally scooped up for almost $5 million less.

Lourdes Alatriste, who specializes in luxury properties and is with Engel & Völkers, made the sale. We’re told the buyers are non-celebs … and not from the area.
