The most expensive real estate transaction ever recorded in New York took place in 2019, when a 24,000 square-foot (2,230 square meters) apartment located at 220 Central Park South was sold for about $240 million. The four-story duplex apartment features 16 bedrooms, 17 bathrooms, a private cinema, a library, a ballroom, and direct access to Central Park. Purchased by  Kenneth C. Griffin, CEO of Citadel, established a new record in the New York residential market.

Previously, the most expensive real estate transaction in New York’s history was the sale of the penthouse apartment in the One57 building in 2014, which sold for approximately $100.5 Million. Since then, several other luxury properties have sold at high prices in New York, including another apartment at 220 Central Park South, which also sold for about $100 million in 2019.

In September 2023, the most expensive property for sale is located at 217 West 57th Street, on the famous “Billionaire’s Row”. The price tag is a staggering $190,000,000 for this 7-bedroom and 11 bathroom  penthouse spanning over 17,545 square feet. This residence is at the top of the tallest residential buildings in the world, standing over 1,548 feet tall with unrivaled views of the New York skyline.
