So, 550 Vanderbilt's a top-selling building? That's if you count closings for contracts signed in 2015.

What are NYC’s top-selling buildings? The Real Deal asked 10/15/17, citing a report from PropertyShark, which "included all sales that closed between July 1 and September 30, 2017, at developments and condo conversions completed since 2012."

So the 550 Vanderbilt condo building at Pacific Park made the list at #7, with 41 units sold.

However, as one commenter wrote:

This article is misleading as to what is really selling... numbers should be based off the contract signed data not closed data... if something was signed 3 years ago and closed 3Q2017... it shouldn't be counted as sold for 3Q2017.

I agree. Many of the 550 Vanderbilt units that closed in Q3 2017 had 2015 contract dates. They just surfaced after the building got its Temporary Certificate of Occupancy and units could proceed to closings.

Hint: #550Vanderbilt is one of them. More in @trdny. https://t.co/CbJGuqRM2e
