Why the Bills Differ So Much
Most of a New Jersey property tax bill pays for local public schools, so towns with highly regarded school districts and fewer commercial properties to share the load, like Mountain Lakes, tend to have higher bills. Towns with more business and commercial property, like Parsippany, can spread the cost more widely.
What It Means for Your Monthly Payment
Taxes are paid monthly as part of most mortgage payments. A $10,851 annual bill, Denville's average, adds about $904 a month, while Mountain Lakes' $24,089 average adds about $2,007. When you compare towns, compare the full monthly cost, not just the price. The mortgage calculator can fill in any of these towns' averages for you.
Check the Specific Home
Averages are a starting point. A specific home's taxes depend on its assessed value and the town's current tax rate, so the bill on a listing can be higher or lower than the town average. Romila pulls the exact figure for every home her clients consider.
