STR, multifamily, or commercial — most Phoenix metro owners save $40K–$200K in Year 1. Arizona SB1350 preempts local STR bans (less regulatory risk than Nashville Type 2 or Miami Beach), the 2.5% AZ flat tax conforms to federal §168(k), and the snowbird + spring training + Super Bowl 2026 event calendar keeps STR FF&E demand high. 30-second estimate, no signup.

National calculators assume stable mid-market rentals. Phoenix metro doesn't behave that way — and four local factors push the math materially in your favor.
Peak STR season Nov–Apr (snowbirds), Cactus League spring training Feb–Mar (15 MLB teams), WM Phoenix Open (largest-attendance golf event in the world), Final Four 2024, Super Bowl LIX 2026. Premium FF&E loadouts compete on event-week and snowbird-season pricing — $40K–$70K of FF&E per Old Town Scottsdale property, all 5-year personal property under MACRS.
Arizona SB1350 (2016) preempts cities from banning vacation rentals — investors have legal certainty Phoenix STR ordinances can't tighten as aggressively as Nashville Type 2 or Miami Beach's ban. Cities can require permits (Phoenix, Scottsdale, Sedona) but the property remains income-producing. Lower regulatory risk = lower cost-seg conversion risk.
Downtown Phoenix (Roosevelt, Garfield, Evans Churchill), Tempe (ASU corridor), Old Town Scottsdale, Desert Ridge, Camelback corridor — all redeveloped or substantially built 2010–2024. Modern code-current HVAC (critical in 115°F summers), electrical, finishes all classify as 5/7-year property — not 27.5-year structural shell.
Arizona's 2.5% flat state income tax conforms to federal bonus depreciation — no decoupling, no parallel state schedule. Your federal Year-1 deduction flows through to your AZ return, adding a small state-level benefit (~7% of total tax savings) on top of the federal 37%. Compare to California where state decoupling forces a parallel schedule on full straight-line basis.

We won't sell you a study that doesn't pencil. Almost everything else — long-term holds, mid-term rentals, snowbird seasonal STRs, Scottsdale portfolios — typically does.
The $495 study still produces a net benefit, but it's small enough that it's marginal — typically $3K–$5K Year-1 savings. Common in Phoenix workforce neighborhoods; worth it only if you're already filing.
Depreciation recapture on sale will eat most of the Year-1 acceleration. Wait, do the 1031 (common CA-to-AZ play), or hold longer.
Everything else — long-term holds, mid-term rentals, snowbird-season STRs, Old Town Scottsdale portfolios, Tempe ASU-adjacent multifamily, recent renovations — typically pencils.
We use RSMeans 2024 cost data with Phoenix metro regional multipliers, Maricopa County Assessor records for land allocation, and the IRS Cost Segregation Audit Techniques Guide methodology. No site visit needed for residential or small-commercial under $5M. An engineer reviews and signs off on every report before delivery.
Full methodology details →Yes — Arizona is one of the most STR-friendly states. SB1350 (2016) preempts cities from outright banning vacation rentals, though cities may require permits and registration (Phoenix, Scottsdale, Sedona all do). None of this affects federal cost segregation eligibility — your federal basis is your basis regardless of STR permit status. AZ's STR-friendly framework reduces conversion risk that exists in other markets (Miami Beach, Nashville Type 2).
Minimally. Arizona has a 2.5% flat state income tax (since 2023). Critically, AZ conforms to federal §168(k) bonus depreciation — there's no state-level decoupling like California. Your federal Year-1 deduction flows through to your AZ return at the 2.5% rate, adding a small additional state benefit on top of the 37% federal savings. Net: federal benefit is ~93% of total tax savings; AZ adds ~7%.
Yes, and Phoenix metro STRs typically benefit MORE than year-round markets. Snowbird and spring-training seasonality means owners stock premium FF&E to maximize peak-season rates: themed bedrooms, premium kitchens, hot tubs, golf-themed amenities. All 5-year personal property under MACRS. Old Town Scottsdale and Arcadia properties typically run $40K–$70K of FF&E density per property.
No. Maricopa County Assessor annual reassessments affect property tax (your tax bill), not the IRS basis used for federal cost segregation. Your cost-seg basis is your acquisition cost from the closing disclosure plus subsequent capital improvements minus land value — not the assessor's full cash value.
Yes — one of the most common CA-to-AZ migration plays. Carry-over basis from the relinquished California property plus any boot becomes the new basis. Cost seg can run on that basis. CA-to-AZ 1031s have grown sharply since 2023 — partly tax migration (CA decoupling vs AZ conformity), partly retiree migration. Your CPA coordinates the IRC §1031 deferral and §168(k) bonus depreciation; the cost-seg study sits on top.
Phoenix is in the top quartile, similar to Nashville and Miami but with a slight state-tax wrinkle. AZ's 2.5% flat tax adds ~7% to total savings vs no-state-tax markets. The MORE meaningful Phoenix edge: state-level STR protection (SB1350) means lower regulatory risk than Nashville's Type 2 or Miami Beach's restrictive zoning. Atlanta actually nets more total tax savings than Phoenix because Georgia conforms to federal §168(k) and adds a 5.49% state-side piece — Phoenix's win over Atlanta is operational (SB1350 STR protection + lighter regulation), not tax.
