What meep said - Westchester is comparable to the Bay Area and most of Puget Sound, and property taxes are... insane. I can't see us ever buying in this county, because neither ginkgo nor I want to spent the equivalent of the price of a new car every year on a taxes for a crackerbox house on a postage stamp of land. Very happy to rent for now.

So no, I don't worry about property prices in Westchester because I'm not that desperate to live 20min closer to NYC. :D
