At $1M, a single-family rental generates approximately $144K in accelerated depreciation through cost segregation — producing about $53K in first-year tax savings. The study cost of $1,295 represents less than 2.5% of the benefit. For investors who qualify as Real Estate Professionals, this entire deduction offsets ordinary income.
Rental properties at the million-dollar level are typically located in high-value markets — suburban Austin, coastal California, the DC metro area, or premium neighborhoods in Denver and Seattle. These homes feature high-quality construction with substantial reclassifiable components: built-in appliances, custom kitchens, upgraded electrical systems, engineered hardwood floors, and extensive landscaping and hardscaping.
At this investment level, many investors are building toward Real Estate Professional status (750+ hours/year in real estate activities), which removes the passive loss limitation entirely. Combined with cost segregation, REPS status transforms rental depreciation into an active weapon against W-2 income. The $53K in accelerated deductions from a single $1M rental can offset a significant portion of a high earner's tax liability.

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.
For long-term rentals, depreciation deductions are generally passive and can only offset passive income. However, there are two key exceptions: (1) if your AGI is under $150K, you can deduct up to $25K in passive losses against ordinary income, and (2) if you qualify as a Real Estate Professional (750+ hours/year in real estate), all rental income becomes non-passive. STR owners who materially participate can deduct against W-2 income regardless.
When you sell a property, the IRS recaptures accelerated depreciation at a maximum rate of 25%. However, the time value of money strongly favors taking the deduction now: $50K in tax savings today is worth far more than paying $12,500 in recapture tax years later. Additionally, a 1031 exchange can defer recapture indefinitely.
