Coconino County, Arizona
Coconino County is the second-largest county by land area in the United States at 18,616 square miles, with roughly 144,400 residents concentrated heavily in Flagstaff. Northern Arizona University and Flagstaff Medical Center drive a large student and institutional rental base, and Grand Canyon and Sedona-area tourism supports lodging and short-term-rental demand. National forest, park and tribal holdings cover most of the county, sharply limiting developable private land and contributing to a median home value of $448,000 — the highest in this group and well above the statewide figure. Median household income is $73,000, so the income-to-price gap is wide, reflecting a substantial second-home and non-resident ownership component.
