Twenty-one contracts were signed last week at $4 million and above, the second week in a row of falling sales. Is this a harbinger of a typically sluggish summer ahead? The No. 1 contract was PH2009 at 1 Central Park South, asking $39.75 million, reduced from $59 million when it went on the market in 2013. The No. 2 contract was the combination of Townhouse A and Townhouse B at 21 East 12th Street, asking $23.5 million.
