Former Morgan Stanley CEO’s $13.5m Manhattan mansion now lists for $80m

John Mack, the former CEO of Morgan Stanley, and his wife Christy are listing their historic New York City Manhattan mansion for $80 million. The Upper East Side property, originally acquired as a carriage house for $13.5 million in 2009, underwent an extensive six-year renovation resulting in a 16-to-20-room luxury residence featuring extensive amenities.

If sold at the asking price, the property would establish a new benchmark for townhouses in New York City. The listing is being presented as a remarkable investment opportunity given the scale of the upgrades and the historic nature of the building.
