These are 2020–2024 medians reported by owner-occupants, not 2026 tax bills or official mill rates. The effective rate here is median tax ÷ median home value. Actual bills depend on assessed value, exemptions (homestead, senior, veteran) and local levies. Check with your county assessor or treasurer. Not tax advice.
