The average home sales price in Manhattan was $100,000 higher than it would have been in the first quarter, thanks to a $238 million condo purchased by hedge fund billionaire Ken Griffin. During the first three months of the year, the average price was $2,118,780 – 7.9% higher than the previous quarter and 9.6% more than a year ago, according to a report from real estate brokerage Douglas Elliman and appraisal firm Miller Samuel Inc. The figures include Griffin’s purchase of the condo at the newly developed 220 Central Park South that went into contract in 2015.
