Yes, cost segregation applies to income-producing residential properties, including townhouses used as rentals. While a primary residence does not qualify, any townhouse generating rental income is eligible. The study reclassifies components like flooring, fixtures, landscaping, and paving from 27.5-year to 5, 7, or 15-year depreciation schedules, dramatically accelerating your deductions and improving cash flow.
