In the NYC metro area, two towns equi-distant from NYC have dramatically different taxes, A $6M house in Chappaqua, NY, would be $126K. The same property in Greenwich, CT would be $45K. So, even by the lower CT standard, Harding NJ is a bargain.
Most towns in NJ are getting killed by the county and state taxes used to fund the huge cess poll welfare cities...even the city of newark has its education system paid for by the state, er, the rest of the taxpayers in the state.
