What is wrong with westchester? It doesn't smell as bad, you can get a place for the same price as nyc with 4x the space and you're only a 1 hr drive away if you don't try to go during rush hours.
A big problem I see with going to westchester to nyc is the parking costs in nyc. Like $50/day is wayyyyyyyy too high to be sustainable. And the trains are just too slow, it is faster to drive from where I am in westchester than take the train.
