Phoenix’s affordable entry points, low land ratios, and year-round warm-weather tourism make it one of the highest-ROI markets for STR cost segregation.
Estimates are for illustration only. Details
The greater Phoenix metro — including Tempe, Mesa, Chandler, and Gilbert — draws STR demand from multiple sources: winter snowbirds, spring training baseball fans, golf tourists year-round, and a growing corporate event scene. Investors buying at $350K–$700K in the Arcadia corridor, Camelback East, and surrounding suburbs typically gross $40K–$80K annually. Summer pool-party bookings and monsoon-season visitors keep occupancy from falling off a cliff.
Phoenix is structurally favorable for cost segregation because land values are low relative to building costs. When land represents 15–20% of the purchase price instead of the 30–40% common in coastal markets, more of your investment sits in the depreciable building. Nearly every Phoenix STR has a pool, which means pool shells, pumps, heaters, automated cleaning systems, and surrounding hardscaping all enter the accelerated MACRS classes. Desert landscaping, drip irrigation, block fencing, and covered patio structures add to the 15-year pool.
Take a $500K ranch-style home in the Arcadia area — a 3-bedroom with a pool, updated kitchen, covered patio, and desert-landscaped yard. The depreciable basis after land is roughly $420K. A cost segregation study reclassifies approximately $126K into shorter MACRS classes: about $88K in 5-year property (cabinetry, countertops, appliances, flooring, bathroom fixtures, lighting, furniture, pool equipment) and $38K in 15-year property (pool shell, desert hardscaping, drip irrigation, block fencing, patio, driveway, landscape lighting).
The typical Phoenix STR investor is a Midwest or California transplant who relocated to the Valley and kept a previous home as a rental, or a first-time investor drawn by entry prices that are half of what comparable markets in California cost. Many self-manage and easily qualify for material participation. The accessible price points mean investors often own 2–3 Phoenix STRs, stacking cost segregation studies across the portfolio to shelter a larger portion of W-2 income.
Arizona has a flat 2.5% state income tax — one of the lowest in the country. Phoenix STR investors capture a small additional state benefit on top of the federal savings. Arizona conforms to federal bonus depreciation provisions, so there are no state-level add-backs or separate depreciation schedules.

View Phoenix Sample Report →No. Cost segregation is explicitly supported by IRS guidelines (Rev. Proc. 87-56) and the IRS Audit Techniques Guide for Cost Segregation. Tens of thousands of studies are filed every year. Our reports are designed to withstand scrutiny — that's why they run 40+ pages with component-level documentation.
Cost segregation is standard practice, not a loophole. The IRS has published formal guidance on how to do it correctly. Every Big 4 accounting firm offers it. We follow the same engineering-based methodology — just faster and at a fraction of the cost.
You'll owe depreciation recapture at 25% on the accelerated portion when you sell. But if you 1031 exchange into another property, recapture is deferred indefinitely. For most investors, the upfront tax savings far outweigh the eventual recapture — especially when you factor in the time value of money.
Most CPAs know about cost segregation but don't proactively recommend it because they don't do the engineering analysis in-house. That's what we provide. Your CPA files the results — we email them a CPA-ready package with everything they need, and we answer any questions they have directly.
Short-term rentals contain a higher concentration of depreciable personal property than almost any other residential property type. Furniture, appliances, linens, kitchenware, electronics, decorative fixtures, and specialty items like hot tubs or game room equipment all qualify as 5-year property under the IRS MACRS classification system. This furniture, fixtures, and equipment (FF&E) component typically represents 15-20% of the depreciable basis.
Beyond interior components, site improvements add additional reclassification value. Driveways, walkways, patios, outdoor lighting, fencing, landscaping, and irrigation systems fall into the 15-year MACRS class rather than the default 27.5-year residential schedule. For STR properties with pools, outdoor kitchens, or fire pits, these components can represent a meaningful share of the total reclassified amount.
With 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act (signed July 2025), every dollar reclassified into 5-year, 7-year, or 15-year MACRS classes is deductible in full in the first year. For STR owners who materially participate in their rental operation, these accelerated deductions can offset W-2 and business income — not just passive rental income.
If your property is a passive investment managed entirely by a third party, the accelerated depreciation may only offset passive income. If your property has minimal furnishings or you plan to sell within 1-2 years, the benefit may be reduced. Actual results vary based on property age, condition, renovations, and local construction costs.

A cost segregation study is an engineering-based analysis that reclassifies components of your property into shorter IRS depreciation categories (5, 7, and 15 years) instead of the default 27.5 or 39 years. This accelerates your depreciation deductions, reducing your tax bill in the early years of ownership.
Short-term rentals are typically furnished with furniture, appliances, electronics, linens, kitchenware, and décor — all of which qualify as 5-year personal property under MACRS. This FF&E (furniture, fixtures, and equipment) often represents 15-20% of the property's depreciable basis, significantly increasing the accelerated depreciation amount compared to unfurnished long-term rentals.
Under the One Big Beautiful Bill Act (signed July 2025), 100% bonus depreciation is permanently restored for 2025 and beyond. This means every dollar of depreciation reclassified into 5-year, 7-year, or 15-year MACRS classes through cost segregation can be deducted in full in the first year you place the property in service.
