Coconino County Property Tax Guide

Flagstaff and Northern Arizona property tax rates, Arizona assessment structure, and senior exemptions

Arizona’s property tax system is structured around a 10% assessment ratio for residential property (compared to New Mexico’s 33% and Texas’s 100%). A $400,000 home in Flagstaff is assessed at $40,000, then taxed at Coconino County’s combined mill rate. The effective rate on market value runs approximately 0.60–0.70% — among the lowest in the Sun Belt.

Arizona Assessment: 10% Residential Ratio

Arizona taxes residential property at 10% of full cash value (market value). This is the lowest residential assessment ratio among Sun Belt states — a structural advantage over Texas (100%), New Mexico (33%), or Florida (variable, but no ratio discount). The combined mill rate is then applied to the 10% assessed value to produce your bill.

AZ Senior Valuation Protection: Homeowners 65+ with income below approximately $39,059 (2025 figure) can apply for a freeze on their home’s assessed value for 3 years, renewable. This is income-tested and designed for lower-income seniors. Most buyers in the Flagstaff price range will not qualify, but Verde Valley buyers at lower price points may. Contact the Yavapai or Coconino County Assessor’s office to apply.

Personal Property Tax on Manufactured Homes

In Arizona, manufactured homes on leased land are assessed differently from real property. They are typically classified under the personal property schedule, not the real property tax roll. The result is a tax structure more like a vehicle registration than a real estate tax — lower annual amounts, but no real estate equity framework. Confirm classification with the county assessor for any specific park property you are considering.
