Tax Assessment

So I received a nice (meaning: horribly complicated) letter in the mail saying my property taxes were going to go up significantly. They said my property, in one year (and a down turn economy), increased in value over $20k! I am going through the appeals process because it IS NOT worth that.
One of the options for the appeal is to send in a copy of the final HUD statement and a copy of the appraisal. I hope they decide to re-evaluate my taxes. I don’t want to be paying for something that sounds OUTRAGEOUS! Yeah, it’s nice if my home increases in value, but this is just absurd!
