Your purchase price

Effective rate 0.36% = this county's median owner-occupied tax bill ($1,386, ACS 2022 5-year estimate) divided by the typical home value at the time ($390,278, 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.
