Answers to common questions about buying a home in Blaine County.
The effective property tax rate in Blaine County is 1.34%, calculated as the median annual property tax paid ($2,080) divided by the median home value ($155,500), using 2024 US Census ACS 5-year estimates. Your actual bill depends on your purchase price, homestead or senior exemptions, and any special assessments applied in your taxing district.
