The actor, who has renewed his wedding vows to wife Luciana Barroso, had bought the house for USD 10.3 million with Barroso, reported Radar Online.
The 12,705 square feet Mediterranean-style house has seven bedrooms and 10 baths, plus a home theatre and wine cellar. The waterfront property sits right on Biscayne Bay and has its own dock.
It also has a swimming pool and pool house. Last August, Damon bought a new estate in Pacific Palisades, not far from their good friends Ben Affleck and Jennifer Garner's house.
