Before you tour San Tan Valley homes
- Because San Tan Valley has no city tax line, a home's tax area, fire district and any association dues come from county records and the home's own disclosure. Check them one home at a time.
- Ask for the association's dues and any special district fee or community tax line, which shows up as an added tax line on the bill.
- Price a home by its estimated monthly payment, not only its list price, so taxes, dues and insurance sit in the same number.
