hopefully youre looking for it to go down to pay less taxes.
its always good to try an appeal, but have good ammo when you go to
fight them. they will usually refuse the appeal if you dont have real good
comparable properties to lower the assessed value.
the comps will need address, sq footage, lot size, beds , baths,
if they sold on foreclosure or regular sale.
remember, you are taking $$ away from them and they are going
to fight you for it.
ps. i had one of my properties reduced 100,000,
saved me $1500 a year so it was worth it
