My experience is that the judges don't really know anything about it and if you throw up enough arguments they will give you half of what you ask. BTW, if you are dead on right with irrefutable proof of value, they'll still give you half of what you ask. Still, half a loaf is better than none.
Go every year, it can't hurt....they would never raise to more than they have already appraised.
We have protested each year and had good results each time.
1) Get the comp. pkt. from the appraisal district
2) Visit each comp. address, take pictures and make notes (business, trailer, etc.)
3) Take pictures of the negative things about your home (disrepair, etc.)
Last year we noted that they were comparing our home to homes of the amount they originally taxed us and not the revised. reduced amount (after our meeting). They noted their error and quickly asked what we wanted.
One time, they had a signature from their appraiser saying he had visited our home. We knew he hadn’t because we are on private property and had to let him in. They asked what we wanted out taxes changed to because he had no notes of the visit.
I asked if businesses are taxed differently than ours. They said, “Of course!” I sighted several of the comp. properties that we found were businesses when we drove to the property.
The first meeting will reduce your taxes a little. We always go to the 2nd meeting (board of 3) and have had success every time. My husband and I both go each time! Have your wife dress attractively .......
