That is not how Westchester is. I would love to live in Westchester or Hudson Valley towns. The problem is due to shitty trains, the commutes are far too long.
Look at a town like Beacon NY. Beautiful place with ridiculously cheap real estate.
If we had high speed trains we could link these cities to NYC for daily commuting and it would pay for itself with increased property values.
There's so much value being lost and inconvenience beared by us because of shitty government.
