In 2022, billionaire Citadel founder Ken Griffin bought a waterfront estate in Miami's Coconut Grove neighborhood for $106.875 million, setting a record for Miami-Dade County. Since then, his record has been broken as other megasales have come to Miami, and Coconut Grove, long a leafy bohemian enclave, has transformed into a billionaire's playground.

Now, Griffin's next-door neighbors in Coconut Grove are listing their home for $110 million, a price that would have been unheard of a few years ago.

The sellers are Howard James Nunes and Karen Romfh Nunes, according to property records. Their family has owned the circa-1920s home for close to a century; the Nuneses paid $6.58 million in 2012 to buy it from Karen's mother, Emily Romfh, who died in 2019.

The Romfhs were one of Miami's pioneering families. Karen's grandfather was Edward C. Romfh, mayor of Miami in the late 1920s.

The 1.6-acre property is one of just a handful on a highly sought after stretch of Biscayne Bay, according to listing agent Ashley Cusack of Berkshire Hathaway HomeServices EWM Realty. With a private dock, it is one of two homes sandwiched between the Griffin residence and the Vizcaya Museum and Gardens.

The Nunes home measures about 5,700 square feet spread across three floors, according to Cusack. The property is in good condition and has been "well cared for" by the family, though it's in need of some modernization, Cusack said. She said it's possible a buyer could look to replace the residence with something larger.

Coconut Grove has been in the spotlight in recent months thanks to several big-ticket transactions. Google co-founder Larry Page recently spent about $188 million on three properties in the neighborhood, and businessman Jorge Mas, co-owner of professional soccer team Inter Miami, sold a vacant waterfront lot there for around $100 million.

Asked if Griffin would be the natural buyer for the Nunes home, Cusack said: "Anything is possible."

Griffin has a penchant for assembling multiple properties in one location. In Palm Beach, he's spent more than $400 million assembling an oceanfront compound since 2012.

Griffin's Coconut Grove property includes two homes, including a circa-1913 home built for onetime Secretary of State William Jennings Bryan. Griffin has proposed relocating the Bryan house to the grounds of Vizcaya, the Mediterranean Revival-style winter home of industrialist James Deering, which has been a museum since the 1950s. Griffin donated $20 million to the museum last year.
