$
Effective rate 1.03% = this county's median owner-occupied tax bill ($2,630, ACS 2022 5-year estimate) divided by the typical home value at the time ($256,561, Zillow, 2022-12-31). Exemptions the seller holds — homestead, senior, veteran — usually do not transfer with the deed, so a new purchase can run above this figure. The county assessor sets the assessed value; this is an estimate, not a quote.
