$60 Million Key Biscayne Home Has Private Harbor, Could Break Record
A home on Key Biscayne has been listed for $60 million. If sold at that price, it would break the record as the most expensive residential property in Dade County.
The 12,000 square foot home was built in the early 1990s on the former site of Mashta House, which was built by W.J. Matheson. It sits on a 2-acre property that juts out into Biscayne Bay and has it’s own private harbor.
Matheson’s Mashta House was built in 1917, but was abandoned in the late 1930s after being damaged by hurricanes.
