Quick Answer: How Do I Estimate Property Taxes?

Property taxes are calculated as: Assessed Value × Tax Rate. The average effective rate is 1.1% of home value nationally, but varies from 0.3% to 2.5% by location. On a $300,000 home, expect $2,000-7,500 annually ($167-625/month). Check the county assessor's website for exact current taxes on any property.

  • Property taxes vary significantly by location (0.3% to 2.5%)
  • Taxes may increase after purchase if assessed value adjusts
  • Homestead exemptions can reduce your taxable value
  • Property taxes are typically paid through escrow with your mortgage
  • Check current taxes AND assessment on any home you're considering
