A $600K Airbnb generates six-figure accelerated depreciation — enough to meaningfully offset a high earner's W-2 income in year one.

At $600K, a short-term rental investment yields approximately $163K in accelerated depreciation through cost segregation. With 100% bonus depreciation, the resulting $60K+ in year-one tax savings represents one of the highest-ROI moves an STR investor can make — especially when the study costs just $795.
Properties in this range are typically in established vacation rental markets: beachfront condos in Destin or 30A, ski-adjacent homes in Park City or Big Sky, or professionally designed urban Airbnbs in walkable neighborhoods. The heavy furnishing requirements of these markets mean an outsized share of the purchase price sits in 5-year personal property — furniture, appliances, linens, electronics, décor, and specialty items like hot tubs and game room equipment.
The material participation strategy is especially powerful at this price point. If you actively manage your STR (most hands-on hosts easily hit the 100-hour threshold), the accelerated depreciation offsets ordinary W-2 income — not just passive rental income. For a dual-income household in the 35% bracket, that's over $57K in real tax savings in year one.

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.
Material participation means you're actively involved in your rental operation — managing bookings, communicating with guests, coordinating maintenance, and making business decisions. If you spend 100+ hours on these activities and nobody else spends more time than you, the IRS treats your rental as non-passive. This allows you to deduct the accelerated depreciation against your W-2 or business income, not just rental income.
