Your purchase price

Effective rate 1.49% = this county's median owner-occupied tax bill ($2,206, ACS 2022 5-year estimate) divided by the typical home value at the time ($148,245, 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.
