”Today, Ono has reported assets of $700 million. She still owns multimillion-dollar properties in Manhattan as well as hundreds of rolling acres in upstate Delaware County, public records show. She lives in the same sprawling nine-room apartment, on the seventh floor of The Dakota, that she once shared with John. She also keeps an adjacent unit at the West 72nd Street building for visitors, and two small one-room spaces without kitchens that she uses for staff, a source told The Post. And she has an office on the first floor that was once used by John as a recording studio.

But Ono has been shedding assets. In 2017, she sold a building at 110 W. 79th St. that she had owned since 1988. She bought the property, housing two residential units, for just under $500,000 and unloaded it for $6,450,000, public records show. In 2013, she sold a 5,700-square-foot penthouse at 49-51 Downing St. in the West Village, which Sean occupied for years, for $8.3 million.
