Westchester County, which lies directly north of New York City, is well known for its many classic suburban communities where cars line up at train stations at 6 p.m. each day to pick up returning executives and money managers. Through the first half of this decade, it was difficult to find homes for less than $1 million in such Westchester towns as Rye, Larchmont, Scarsdale, Chappaqua and Bedford.
