Challenging a tax assessment? Worth it?

[Daniel Cavallari]

I was wondering if anyone has any insight into challenging a tax assessment of their property. Is it worht it? I don't actually think my assessment is too off, maybe $4k greater than its value. However I did note that my tax assessment is $10k - $15k greater than nearby (within a block) comps. My property is located in NYS so a $5k to $10K reduction in tax assessment would result in a several hundred dollar reduction in my property taxes. Let me know your thoughts. Thanks!
