I'm surprised that I never chimed in on this thread before, so I'll bite. I live in White Plains, NY. The frum community is definitely a little more modern, but we have two orthodox shuls (Young Israel and Hebrew Institute) with about 350-400 families.
The pros
- It's a relatively affordable community still within a stone's throw of NYC.
- Taxes are relatively good (but not great) most 4Bd will run between 10-13K per year
- Metro North to midtown is about 35-40 minutes by train, and reliable
- Conveniences of a city - supermarkets open late (Every once in a while I'll find myself in stop and shop at 11pm on Thursday getting the one thing my wife needs to finish cooking for shabbos and I meet 5 other people doing the same thing), 24-hour pharmacies.
- Not far from anything - in less than an hour you can be in Riverdale (20m), Monsey (30-35), Queens (about 40), UWS (25-30), Teaneck (35-40)- and Five Towns or Brooklyn on a Sunday morning.
The cons:
- Lack of restaurants - there's Pizza and Chinese in New Rochelle
- Only one large kosher supermarket nearby, and it's expensive (but most people go to Costco in New Rochelle, which has kosher meat or buy meat/cheese in Monsey/Riverdale/Queens)
- Yeshiva Choices - there are a few, but they're all co-ed - works for some, not for others.
I'm sure that for many of you this might not be a good fit, but if you have any interest and want to know more, please feel free to DM me.
