Ken Griffin pays $45M for Julia Koch’s prestigious Park Avenue co-op

By Aaron Ginsburg

Billionaire Ken Griffin has added another exclusive address to his real estate portfolio. The Citadel founder bought a palatial co-op at 740 Park Avenue, one of New York City's most prestigious cooperatives, from fellow billionaire Julia Koch for $45 million, according to the Wall Street Journal. The deal marks one of Manhattan's most expensive co-op sales on record, as CityRealty noted. Koch purchased the home with her late husband David Koch in 2004 for $17 million and originally listed the property in 2022 for $60 million.

A $26M duplex co-op in Jacqueline Onassis’ childhood building recalls the Gilded Age

By Michelle Cohen

A mansion-sized 14-room duplex at 740 Park Avenue, a building considered to be Manhattan's most luxurious residential address, is now on the market for $26,000,000. Built in 1929 by James T. Lee, grandfather of Jacqueline Bouvier (later Kennedy Onassis), who lived there as a girl, the Art Deco building was designed by Rosario Candela. One of its first notable residents was John D. Rockefeller, Jr., who resided in a duplex similar to the one featured here.

Steven Mnuchin lists swank Park Avenue co-op for $33M

By Michelle Cohen

Treasury Secretary Steven Mnuchin has just listed the Park Avenue duplex that has been in his family since the 1960s for $32.5 million, the New York Post reports. Mnuchin bought the 12-room, 6,500 square-foot Upper East Side duplex from his aunt for $10.5 million in 2000, so even if the co-op in tony 740 Park Avenue doesn't fetch the ask, he'll pocket a tidy profit. The Rosario Candela-designed building is known for its wealthy residents who have included Rockefellers, Kochs and Bronfmans as well as being Mrs. Onassis' childhood home. The former Goldman Sachs investment banker and Hollywood film producer was based in California before accepting a position with the Trump administration and has never claimed the Park Avenue home as his primary residence.

After three years, Jacqueline Kennedy Onassis’s childhood home on the UES sells for $25M

By Dana Schulz

James T. Lee, Jacqueline Kennedy Onassis' grandfather, was a prolific NYC developer at the beginning of the 20th century, bestowing upon the city some of its most elegant co-ops like 998 Fifth Avenue and the Rosario Candela-designed 740 Park Avenue. He himself took up residency in the latter building when it was completed in 1930 and gifted another apartment in the Upper East Side building to his daughter Janet and her husband John V. Bouvier; Jackie O lived there with her parents between the ages of two to seven. In more recent years, hedge fund manager David Ganek and his wife bought the duplex in 2005 for $19.1 million, using it to also showcase their impressive modern art collection. The couple first listed the home for $44 million in 2014, and after several price chops, it's finally sold $25.25 million reports the Journal. Jacob M. Safra of the billionaire Safra family, of Brazilian banking fame, is the buyer.

Jacqueline Kennedy Onassis’s childhood home gets a major price cut to $29.5M

By Emily Nonko

There have been some big price chops for an apartment at 740 Park Avenue, one of New York's most iconic co-ops, once lived in by Jacqueline Kennedy Onassis herself. The former first lady—whose grandfather developed 740 Park in 1929—lived in this apartment between the ages of two to seven. It is now owned by David Ganek, a hedge fund manager, who has used the Rosario Candela-designed co-op as a home for his impressive modern art collection. He first listed it in 2014 for $44 million, and now it's on its third price chop down to $29.5 million.

Timeless Trophy: 740 Park Avenue

By Dana Schulz

New York City may have an ever-revolving cast of hottest restaurants, hippest clubs, and even most desirable neighborhoods, but some real estate titans never go out of style in this metropolis. Known as the "Tower of Power," 740 Park Avenue is one such mainstay. The Upper East Side 19-story, Art Deco building was completed in 1930 to the designs of Rosario Candela, often considered the finest architect of luxury apartment interiors, as the last of the grand dames erected along Manhattan's Gold Coast. It didn't reach its peak until the real estate boom of the 1980s, but is today one of the most sought-after addresses with 31 apartments, mostly all duplexes, triplexes, and penthouses. The massively scaled residences feature grand living rooms, formal dining rooms, spiral staircases, high ceilings, expansive foyers, and an abundance of windows.
