Delaware property tax calculator
Delaware homeowners pay $1,768 a year at the median. This amount equals 0.50% of the $352,000 median home value.
This figure is an estimate, not an actual bill. Your county assessor (or an appraisal district in some states) determines your value, while local taxing units set the rates. Check with your county before you pay or file a protest.
