Longboat Key mansion sells for record-setting $30 million. Take a look inside
A Longboat Key mansion recently sold for $30.3 million.
It’s a record-selling price for Florida’s west coast, excluding Naples, said Coldwell-Banker Realty’s Judy Kepecz-Hays,who represented the anonymous buyers. They paid cash for the 19,300-square-foot mansion named Serenissima.
Serenissima means, “The Most Serene,” which references Venice, Italy when it was an independent republic.
The property, located at 845 Longboat Key Road, has six bedrooms, six full bathrooms, two half bathrooms, a 12-car garage, gated security and is steps away from the Gulf.
“The Gulf is your backyard and the golf course … is your entryway,” Kepecz-Hays said. “It’s hard to beat everything this home has to offer.”
The three-story home last sold in 2020 for $16.5 million, according to Sarasota County property records. Compass listing agent Rich Polese facilitated the mansion’s sale in 2020 and in 2025.

“This home has always been one of the most special properties on the Gulf Coast, and I’ve admired its craftsmanship and timeless beauty for years,” Polese said in a news release. “To see it sell for $30.3 million in such a short time on the market is not only a milestone for Sarasota but a reflection of how strong an investment in the market is. It’s gratifying to help match such a remarkable home with the right buyer.”
Serenissima was built in 2005 and sits on 1.18 acres. In addition to the living space, the estate has private beach access, an infinity-edge pool, spa and pool deck.
The home features a “marble hall crowned by a glass sky dome,” according to the listing. There is also a 10-seat home theater, light-filled sun room, gourmet chef’s kitchen, Venetian murals, an elevator and terraces offering panoramic views of the pool, beach and Gulf of Mexico.
“They were looking for a larger home,” Kepecz-Hays said of the anonymous buyers. “They love their family. They have children and grandchildren. And they love … to have them around them, and they wanted a home on the beach. … It was more the size and the quality of this home that made them go forward with it. They immediately fell in love with it.”
The home was on the market for 25 days before it sold on July 31.
