This five-story Beaux-Arts home on the Upper East Side is the primary residence of the former billionaire mayor of NYC. He purchased the 7,500 sqft townhouse in 1986 for $3.5 million. Over the past two decades Bloomberg has bought up parts of the adjacent house to the right and combined them with his home (total of about 12,500 sqft).
