Does hiring someone help?

Whether an agent helps is not settled here: the advantage has changed sides between years, ahead in 4 and behind in 1. A single combined figure would report whichever side the window happened to favour.

Each year: how many percentage points better an agent did than an owner filing alone. Negative means the owner did better.

Firms that file on your behalf commonly take a third of the first year's saving. This is the county's own record of how the two groups actually did.

The reasons the Assessor gave

Every decision carries a stated reason. These are the ones that appear most often on Thornton decisions, and how often each was attached to a reduction rather than a refusal.

A reason seen fewer than 30 times shows no rate, for the same reason a township with a handful of appeals shows none.
