Billionaire Bill Ackman just took a nearly $4 million hit selling his Central Park West apartment for $9.43 million—way below the $13.5 million he paid in 2017. Despite the loss, Ackman seems unfazed, saying he’s happy to move on after not living there for seven years. The iconic Beresford building has seen celebrity owners like Jerry Seinfeld and Diana Ross, but even big names aren’t immune to the city’s unpredictable real estate market. Would you hold onto a place for years, even if it meant selling at a loss? #RealEstate #NYCRealEstate #CentralPark
