Even a modest rental property contains thousands of dollars in reclassifiable building components that most investors leave on the table.

The conventional wisdom that cost segregation "isn't worth it" for properties under $500K is outdated. At $300K, a single-family rental still generates roughly $43K in accelerated depreciation — translating to about $16K in year-one tax savings against a study cost of $795. That's a 20x return.
The components that get reclassified in a typical SFR include: electrical outlets and wiring dedicated to appliances (5-year), cabinetry and countertops (5-year), carpet and vinyl flooring (5-year), decorative lighting fixtures (5-year), landscaping and irrigation (15-year), driveways and sidewalks (15-year), and fencing (15-year). These aren't obscure line items — they're standard features of any rental property.
The key consideration for long-term rental investors is the passive activity loss rules. If your adjusted gross income is under $150K, you can deduct up to $25K in passive losses against ordinary income. Above that threshold, you'll need other passive income to absorb the deductions — or you can carry them forward to offset gains when you sell.

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.
