I have an informal scheduled for Tuesday morning. We are fairly new construction. I successfully protested value during the build which straddled 1/1/22, but HCAD still has us at about 350SF larger than actual. I obtained a SF only appraisal that confirms our correct SF. The plan was pretty much to just argue for a prorata reduction in the improvements value based on the incorrect SF. But, within days of filing my protest, I got an offer for a 4% reduction on the incorrect SF appraisal. So, I got an "appraisal contestation report" from protestingpropertytaxes.com to have comparable sales data based on the correct SF. I am cautiously optimistic for a good result.
One note about protestingpropertytaxes.com. They factor in only land and house SF. They do not include or factor in garage and/or porch SF, both of which HCAD includes as individual factors in valuation for the improvements. I assume that is standard - that other CADs do so too. I've now compiled those numbers from HCAD, and the protestingpropertytax.com comps have garages ranging from 432 to 805 SF, and porches ranging from 68 to 572 SF. I'll be pissed if HCAD points that out as reason my comps are not true comps, or that the adjusted value of my comps are not accurate and reliable....
