Ask someone outside Arizona to picture retirement in the state, and they land on Scottsdale. Ask an Arizonan who actually retired here, and they will tell you they live in Prescott, Green Valley, Sun City West, Payson, or Oro Valley. Scottsdale is where retirees vacation. For most, the numbers do not work there. Here is the math.
Where Arizonans Actually Land
The archetypal Arizona retirement town is Green Valley, about 25 miles south of Tucson. Age-restricted, walkable to a clinic, and priced for people who sold a paid-off house in Phoenix and want the difference to fund the next 25 years. Prescott and Prescott Valley catch retirees who want four mild seasons and pine trees. Sun City and Sun City West, both in the Phoenix metro but far from Scottsdale pricing, still absorb the largest share of in-state movers. Payson and Show Low serve the high-country crowd, and Yuma and Lake Havasu City pull the snowbirds who eventually stay year-round.
What these places share: a paid or nearly paid house, low property taxes, and enough medical infrastructure to matter. National home prices sit at an index reading of 335.1, in the 90th percentile historically, and Scottsdale trades at a heavy premium. Green Valley does not.
The Real Cost Picture for a Green Valley Couple
Take a married couple, both 66, buying a modest 1,600 square foot patio home in Green Valley outright for around $340,000. Property tax runs roughly $2,000 a year. HOA and community fees add another $1,500. Utilities including summer AC come to about $3,600. Home and auto insurance with an umbrella policy, another $2,800.
Food for a couple at the USDA moderate-cost plan runs close to $10,800 a year. Healthcare on Medicare Part B, a Plan G Medigap, and Part D for two people lands near $9,600 all in, before dental. Transportation with gas at $4.01 a gallon and long Arizona drives, roughly $6,500. Everything else (travel, gifts, home maintenance reserves, a replacement vehicle sinking fund, and federal taxes on withdrawals) needs about $18,000.
That totals roughly $54,800 in fixed living costs plus $18,000 for reserves and taxes, so call it $72,800 a year. For reference, the average U.S. household spent $78,535 in 2024, so this is disciplined but not austere.
The Math That Turns Budget Into Portfolio
Social Security does the heavy lifting. A couple with one higher earner and one lower, both claiming at full retirement age, commonly sees combined benefits in the $54,000 to $58,000 range. Use $56,000. The 2027 COLA is currently tracking at 3.1%, which matters because that benefit is inflation-linked and the portfolio is not.
Subtract $56,000 from $72,800 and the annual gap is $16,800. At a 4% withdrawal rate, that requires a portfolio of $420,000. At a more conservative 3.5%, which we suggest for a couple planning to 95, it is $480,000. Add a $50,000 emergency reserve outside the withdrawal math and you land at roughly $530,000 in investable assets on top of the paid-off house. That is well short of two million, and well short of Scottsdale.
Delaying Social Security to 70 flips the equation. The same couple claiming later might pull $70,000 combined, closing the gap entirely and letting the portfolio breathe. A treasury ladder or short-duration bond position bridges the gap from 66 to 70.
The Sales Tax Trap and the Wildfire Line Item
Arizona ranks 15th overall on the 2025 State Tax Competitiveness Index, with an 8th-place individual income tax rank, which sounds like a retiree’s dream. Social Security is not taxed, and the flat 2.5% income tax barely dents a modest withdrawal. But the state ranks 45th on sales tax, and combined state and local rates in retirement towns commonly land above 9%. Every dollar of that $18,000 discretionary bucket gets taxed on the way out. Over 25 years, that is real money.
The second missed item is insurance in the high country. Prescott, Payson, Show Low, and much of the Mogollon Rim now sit inside insurer wildfire maps that have re-rated premiums sharply. Homeowners policies that ran $1,400 a few years ago are quoting $3,500 to $5,000, and non-renewals are no longer rare. If your Arizona retirement is pine trees rather than mesquite, add $2,000 a year for insurance volatility. Green Valley and Sun City West do not carry that risk. Prescott does.
What It Actually Takes
To retire in Arizona the way Arizonans actually do it, own the house outright in a lower-cost retirement town, budget around $72,000 to $75,000 a year in current dollars for a couple, and hold roughly $500,000 to $550,000 in investable assets alongside Social Security claimed at or near full retirement age. Use a 3.5% withdrawal rate if you want the plan to survive a long life and a bad first decade of returns. Build the sales tax and, if you go north, the wildfire premium into the plan from day one. That is the version of Arizona retirement that works. Scottsdale is the postcard. The rest of the state is the plan.
