The question is not as easy to answer as you may think... yes, we can all certainly name towns in each of those counties with lower property taxes but the bigger question is this -- what services are you looking for in a community? What kind of balance of residential to commerical development? Quality of public school systems? Recreation programs? Garbage collection? Paid versus volunteer fire departments? Proximity to NYC transportation? All these issues go into property taxes, along with the style of house, size of the overall lot, upgrades in the house, etc. Each town also is on a different schedule with the state as far as reassessment, some towns have done this in the last five years and some have not. There are 70 towns in Bergen County with varying socio-economic levels and housing price ranges, and each is slightly different.
I can name a handful of Berge County communities with lower property taxes, depending on your price range -- Fair Lawn, Maywood, Elmwood Park, Franklin Lakes, Paramus, South Hackensack, etc. But in a town like Franklin Lakes or Paramus, the housing prices start much higher than the other communities, because of lot size, square footage and style of house, etc. The same split level in Teaneck will cost you about $150,000 more in Paramus, because Teraneck's property taxes are higher (it's 84% residential) and Paramus benefits from a large commercial tax base due to all those malls and stores along Rt. 4 and Rt. 17. Just keep in mind that currently we still have Federal income tax deductions for both mortgage interest and property taxes, which can change your bottom line tax picture dramatically. Look for a community you want to live in and raise your family in, that should be your priority.
