Developer Carlos J. Tosca quietly cashed out of his waterfront Coral Gables mansion this month, selling the Sunrise Harbour spread at 6850 Sunrise Court for roughly $16 million. The gated, boat-friendly home had been one of the neighborhood’s splashier listings since it hit the market earlier this year.
According to the South Florida Business Journal, Tosca closed the deal with a buyer tied to a venture capital firm. The outlet also published a 33-photo gallery that walks through the home’s waterfront terraces and polished interiors.
About the house
Listing materials and MLS data describe the property as a six-bedroom, eight-bath home with about 5,551 square feet of living space on roughly a 0.32-acre lot, complete with a private dock and direct ocean access inside gated Sunrise Harbour. Marketing copy and amenity lists are highlighted on Compass and other broker sites.
Sale details
Public listing platforms show the sale recorded earlier this month for roughly $16.3 million, a tick above the $16 million figure reported by the Business Journal, with closing information and price history laid out in the online records. The transaction notes and timeline are visible on Redfin.
Seller background and what it means
State records list Tosca as president of Tosca Real Estate Corporation and connect him with the Coral Gables address, according to filings from the Florida Division of Corporations and related business profiles.
The deal lands in the middle of a run of high-end, often off-market waterfront trades in Coral Gables, a trend brokers say is thinning out turnkey options for buyers who want ready-to-go waterfront homes. Recent reports on other hush-hush closings in the city underscore that pattern, including a $36 million off-market waterfront trade earlier this spring.
