Both my spouse and I are from out of town. We are constantly thinking about moving out of Brooklyn.
The fact is although rent/mortgage is likely to be much cheaper out of town, chinuch costs are at least double. Who can afford multiple tuitions in a small community where there is a much smaller base for raising funds. The schools are also less likely to give serious tuition reductions.
I will follow this thread to see if anyone has any solutions to these issues.
