A cost segregation study is an engineering-based tax strategy that reclassifies components of a real estate property from the standard 27.5- or 39-year depreciation schedule into shorter 5-, 7-, or 15-year categories. This accelerates your depreciation deductions, significantly reducing taxable income in the early years of ownership. The result is improved cash flow and a powerful tool for reinvesting in additional properties.
