For those of you looking to make the move, Bloomberg BusinessWeek published a recent article highlighting an often over-looked community, Clark, NJ. With a population under 14,000 and a median family income just under $100k/year, this is a town that has managed to maintain lower taxes (5k-9k/year), while still having excellent schools, relatively low crime and pollution, lots of green space in relationship to developed space as well as have a fair commute to NYC if you need it. It doesn't have its own station, but nearby stations do provide train access. There is a handful of newer construction homes that top almost $1M in home price, but there are also a large number of reasonable starter homes that range between 300k-550k. These prices, coupled with a lower tax rate, often make for more affordable living, as well as a nice community vibe (town pool, small schools, golf & tennis, parks, etc.).
