Hi Terrie!!!
Ironically two years ago exact almost I moved from Taylor MI to Westchester--- I am in a town north of White Plains-- and I am going to be honest with you... there is NOTHING IN WESTCHESTER whatsoever in the price range of MI. Honey, this county is one of the wealthiest in the country--- you knew that right???!!!
Well with that said I suggest Peekskill, Mt. Vernon, New Rochelle, Tarrytown, Elmsford and White Plains.... there is a town called Greenburgh right by White Plains (but it can be expensive-- it however is the most diverse here).The schools are excellent for the most part in all the areas.
This place will be a shock to your pocket!!! Good luck!!!
