Completely Random Property Taxes

[Christopher Guerriero]

I own three houses in Ewing, NJ. The property taxes are high like all of New Jersey, but what confuses me is the lack of a standard property tax rate. The three tax assessments, taxes, and effective rates on my houses are as follow, ($170,600, $7,040.91, 4.127%), ($140,200, $6,665.88, 4.755%), and ($171,000, $6,021.48, 3.521%). All three houses are in the same tax class, same neighborhood and all around similar. Picking any house at random in the town and you will get a different tax rate in relation to its tax assessment. Is there any explanation that anybody would know of? I never gave it much thought until recently and would like to have a better understanding of the situation.
