Your best bet is to look at comparable sales to your property within the last 6 months. The "assessment" is not necessarily equivalent to the "market value". That's why recent sales are so important. Zillow is known to be accurate about 50% of the time, so it's dangerous to base any conclusions on it. My suggestion is to ask a local realtor for help with the recent sales. I've done that here for folks just as a service...with no obligation! If the recent sales are lower than your assessment, then, by all means, I'd recommend appealing your assessment. If you do, be sure to go armed with this information.
Good luck! Please let me know if I can be of further assistance or if you need a dependable realtor contact in Millville. I'd be glad to help.

The county does NOT assess properties in NJ, local municipalities do. If you have a real issue with your taxes, there is a procedure to be followed that allows you an appeal. You might start by visiting the local tax office and getting up to speed. A Realtor then might give you some free comps but if they are not done the way the tax law prescribes, they may be worthless.
I would take zillow with a grain of salt.
And, NO I am not interested in working on any tax appeals myself.
Best of Luck!
