With the post-Hurricane Sandy heightened awareness of waterfront living and flooding risk, I thought I’d provide a visualization of where the top 1% most expensive properties in Manhattan are located. Manhattan’s top 1% of the housing market starts at $10M. I presented all the co-op, condo and 1-3 family townhouses that closed at or above January 1, 2003 in Manhattan. I used the same data set (but updated) when I presented the Tallest Chart in the History of Manhattan Real Estate  a while back.
Fairly consistent pattern – clustered around Central Park and lofts downtown with only a handful along the waterfront.
