ways to lower tax assessment

[George P.]

Just received my assesment, taxable valuation and property classification notice for 2012. although the taxable value has decreased on all houses, the tax bill actually increased by average of $700 for the year.

I wrote a letter to the assessor's office last year and the wanted me to pay $25 per case and go to court at the state capital. i dont have the time nor the experience to go that route.

Is there a way to fight this legaly? tax attorney? how much would it cost me?
