Probably about 30 families in Blue ridge give or take. Rav Daniel Kalish is amazing! Mod 42 is right about the commute, although 1 and 1/2 hours is something people from Lakewood and elsewhere do as well.
There are a number who work from home or local offices such as accountants and day traders. Also some go in only a couple of times a week, still a shlep but not everyday.
Brand new houses run something in the 250K range. (I think). Of course more can be spent.
Yeshiva community (that 4 min drive or 40 min walk on shabbos) has probably close to 200 families give or take. Large Yeshiva Ktana with probably 350 or so children. Started that girls high school and I hear talk of starting a boys as well .
