Flagstaff mortgage calculator
A median-priced Flagstaff, AZ home at 6.75% over 30 years, with Arizona property tax of 0.62% and $1,700 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$4,262 a month, all in
Principal and interest are $3,555; escrow and PMI add the rest. Over the full term the loan costs $731,688 in interest. Discounted at 5%, buying here has a net present value of $-10,109 ($334,173 in today’s dollars).
Within Arizona, Flagstaff is 2nd of the 7 Arizona markets covered here, between Scottsdale at the top and Tucson at the bottom of a 2.33x spread. A state-level median hides most of that.
Flagstaff carries a premium over the rest of Arizona: a median home here runs $609,000, about 40% above the state median of $435,000. The deposit moves with it, so the same 20% down is $121,800 rather than $87,000.
Prices here have run ahead of rents: the local price index sits at 1.40 against a rent index of 1.20. A market where buying costs rise faster than renting does is one where the rent-vs-buy answer leans later — you need a longer hold before ownership wins.

Where these numbers come from
Arizona medians come from editorial and are refreshed weekly. The Flagstaff figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
