I’m in Texas. I didn’t know there were fees to protest but I will look into that. I was under the impression you make an appointment, show up at the allotted time and it is pretty much cut and dried that your taxes will be lowered. Also, there are companies that specialize in tax bill protests.
Good luck. Unless you have the right comps, you won't get much. I tried fighting it a couple years ago. Before the hearing, they offered a 1% reduction; I thought I had evidence to warrant a reduction of about 8%. After politely listening to me, their case was presented using comps I considered highly unreasonable, and the panel voted to approve the 1% reduction.
This was in Collin County. Our 1:00 appointment consisted of 20 people being ushered into the room to await their turn. I was first; perhaps they wanted to make an example of me in hopes that some of the others would give up and leave before their turn came up.
