I live in PB and can say, it’s difficult to find a block without a place for sale. This last Sat. I drove down a street where there were six houses for sale.
I am pretty sure there are a lot of Alt-A and “creative” loans in that area. I use this website to get a general idea of zip code “distress”. No exact numbers but some sort of idea can be gleaned from it. http://www.newyorkfed.org/mortgagemaps/
