Protest your taxes IN PERSON & EARLY.

You may gather the comp's from a Realtor similar to your house.

Best is find a home that is similar to your own home, paying less taxes than you.

Take pics of your home outside only of where your home HAS NOT BEEN UPDATED.

HAMMER HOME, (pun intended) all the things wrong with your home. Make you home seem barely livable yet no need to be condemned.

In my county in Texas, the appraiser told me there is three ratings, CURRENTLY UPDATED & READY TO SELL, Updated & NO UPDATES from original build.

Go for the one most applicable to your home.

I RECEIVED THE no updates from original build, except new roof.

I had pics & showed my front door damaged, busy Main Street, power lines.

I showed my house in the worst light with a ONE ON ONE MEETING WITH APPRAISER.

LEARN TO PLAY THE GAME. GOOD LUCK.

I live in the north DFW area.
