Get with a local realtor and have them run some comps of sales during the previous calendar year.
Our realtor provided, made clear why these comps mattered (age of house, proximity, size of lot, etc). I got this, uploaded to Denton CAD and wrote a brief explanation.
They had increased me at the full 10% and their settlement was to go back to the previous value (no increase) I had lowered that when we got a great deal on the house at the end of 2019.
Sent the realtor a nice thank you gift.
