The New York Times created another super cool graphic in their new Calculator  column, based on my idea. In the fall of 2015 I observed a massive surge of sales in Westchester County (north of NYC for those not familiar with our area). However median sales price was nearly flat during this period. This was phenomenon repeated in all of the counties that surround NYC – except for NJ since I don’t cover that market yet but anecdotally I believe the same phenomenon is occurring there. I believe this moment was the point where the affordability challenge became so severe that renters and move up buyers had to move out of the city.
Specifically, Brooklyn showed a surge in median sales price from 2009 with a modest growth in sales. Westchester reflected the opposite patterns of Brooklyn. Westchester county sales boomed over the same period while the growth in median sales price was much more tepid.
Below is the NYT graphic for the suburban sales boom article .
