An 11,500-square-foot home on Biscayne Bay is about to hit the market for $60 million. If it actually fetches that price, it would become the most expensive home ever sold in Miami.

The high price tag for 775 S. Mashta Drive, on Key Biscayne, an island off Miami’s coast, is due to the land, not the house itself. The property encompasses two acres and 2,000 feet of water frontage and is comprised of three buildable plots, meaning that two additional homes could potentially be constructed. “I dare to say it’s one of the nicest pieces of property in all of the Eastern Seaboard, not just Miami,” says listing agent Jorge Uribe of ONE Sotheby’s InternationalRealty.
