That makes sense. I was curious because my boss who lives in Plano neglected to homestead so he was getting violated on his taxes. I discovered it, we filled out this form and talked to that person and eventually got him several thousand dollars of retroactive credit.
My house was assessed at something like $130k the year before I bought it and two years later it's in the $230k range, but I'm fine with it as the old assessment was based on a structure that was torn down and my current house was built brand new on the original footprint. So it's more or less assessed at what I paid for it.
I do get amused trying to explain to people out of state how property tax protest is pretty much the national sport of Texas.
