What's the property tax rate in Flagstaff?

Flagstaff's median effective property tax rate is about 0.47% of market value, below the Arizona median and less than half the national norm. But your all-in rate depends on which school, fire, library, and community-facilities districts your address sits in — all-in effective rates typically run about 0.7% to 1.2% of assessed value. The calculator defaults to 0.6% as a middle-ground estimate; verify the exact levies for a specific address with the Coconino County Treasurer at coconino.az.gov.

What's the current average rate for a 30-year fixed in Arizona?

Rates change weekly. The Freddie Mac Primary Mortgage Market Survey publishes the national 30-year fixed average every Thursday at freddiemac.com/pmms. Use that as your reference, then compare against actual quotes for your loan amount, credit score, and down payment.

Does the calculator include PMI?

No. Private mortgage insurance applies when you put less than 20% down on a conventional loan and typically runs 0.3% to 1.5% of the loan amount annually. Add that to the insurance line if you're putting down under 20%, or ask James to point you to a lender for an all-in PITI quote.

Why is homeowners insurance a variable here?

Flagstaff sits inside the world's largest ponderosa pine forest, and insurers price wildfire exposure — some homeowners near burn-scar drainages have seen sharp premium increases, and post-fire flood insurance can be a factor in affected areas. Premiums vary meaningfully by location and construction, so the $1,400/year default is a starting point to overwrite with a real quote, not a promise.

Should I wait for rates to drop before buying new construction?

Flagstaff is a supply-constrained market — about 73% of the surrounding land is national forest, and the best lots in each phase go first regardless of the rate environment. The counterweight: 2026 is the most balanced market Flagstaff has seen in years, with homes averaging about 59 days on market versus 44 a year earlier, so buyers have more room to negotiate than at any point since 2019. Run the numbers both ways rather than betting on a rate future nobody can predict.

Model a builder financing incentive (−1.5%).Builders often attach rate incentives to their preferred lenders, and terms change month to month. A 1.5% reduction on the numbers above would save $643/month — ask James what Capstone is currently offering.

How the math works

Your monthly payment has four parts: principal & interest, property tax, homeowners insurance, and, if the community has one, HOA. The principal and interest portion uses the standard amortization formula:

M = P × [ r(1+r)^n ] / [ (1+r)^n − 1 ]

P = loan amount (price − down payment)
r = annual rate ÷ 12
n = term in months

Property tax is computed as the annual rate applied to the purchase price, divided by 12. The 0.6% default splits the difference between Flagstaff's ~0.47% median effective rate and the higher all-in rates that school, fire, and community-facilities districts add in some areas — typical bills run roughly $2,020/year in ZIP 86004 and $2,639 in 86005. Insurance is annual ÷ 12. HOA is a flat monthly figure: Timber Sky and Canyon del Rio carry community HOAs, and Aspen Ridge II sits inside the gated Flagstaff Ranch Golf Club, where club amenities come with their own costs — ask James for current dues on the community you're considering.

Reverse mode: what can you afford?
