I think the term "inexpensive" is relative. If you compare it to other Westchester communities, yes, it will be less expensive to live there. It is very close to the Cortlandt Train station, where you can catch locals and express trains. See link provided for station info:

Slightly north of there, you can go the the farmers market in Peekskill to purchase some locally grown items. See link...
