Lennar’s Eric Feder and Sintavia’s Brian Neff separately bought and sold a pair of Fisher Island condos — with both deals tied to the same Delaware company — for a total of $27.6 million.

Records show LHOTSE LLC, the Delaware entity, sold unit 7181 at Palazzo Del Mare to Feder and his wife, Elizabeth Feder, for $11.8 million. The same Delaware entity bought unit 7133 in the same building from Sintavia CEO Neff and his wife, Jana Neff, for $15.8 million, according to records.

Cyril Matz of Douglas Elliman represented both the buyers and the seller in the deal for unit 7181.

Martin Alex Weinstein Diaz signed the deed with the Feders, and both deeds link to the address of a Miami home he bought for $5.3 million in October. 

Neff’s Fort Lauderdale-based Sintavia uses 3D printing techniques to manufacture components for aerospace, defense and space industry machinery. Lockheed Martin invested in the company in June, according to a press release.

Feder is president of Lenˣ, Miami-based Lennar’s venture capital division. Before joining the homebuilding giant, he was a vice president with Rialto Capital from 2008 to 2018. In 2022, he and his wife sold a waterfront Aventura home for $11.9 million

The Palazzo del Mare unit the Feders purchased spans nearly 3,700 square feet, with four bedrooms, four bathrooms and one half-bathroom, according to property records. The Delaware entity had bought the unit for $5.8 million in 2014.

The unit the Delaware entity just bought from the Neffs is almost double that size at 7,000 square feet. It includes four bedrooms, five bathrooms and one half-bathroom. The Neffs bought it for $5.8 million in 2009, according to property records. Although the deal closed off-market, Matz listed the condo for $18.9 million in December of 2022, and dropped the asking price to $16.9 million in June, Realtor.com shows. The listing was removed in November.

Palazzo Del Mare is a 10-story, 28-unit condominium on Fisher Island, a private island off Miami Beach. Only accessible by ferry, boat or helicopter, the island is one of the wealthiest ZIP codes in the U.S., and is a popular enclave among South Florida’s luxury buyers. 

Other recent deals on Fisher Island include developer and pizza mogul Sal Lupoli’s $14.2 million purchase of a renovated condo in October. In July, private equity investor Michael Flacks bought a unit for $24.2 million. That same month,  garbage mogul Patrick Dovigi sold a condo for $20 million
