A cost segregation study is an engineering-based analysis that reclassifies components of your real estate from standard 27.5- or 39-year depreciation schedules into shorter 5-, 7-, or 15-year categories. This accelerates your depreciation deductions, lowering your taxable income significantly in the early years of ownership. Michigan property owners typically convert 20–40% or more of their building's cost into immediate deductions, resulting in substantial cash-flow improvements.
