Cost segregation is an IRS-approved tax strategy that reclassifies components of a commercial or residential investment property from 27.5- or 39-year depreciation schedules into shorter 5-, 7-, or 15-year categories. For Texas property owners, this accelerates deductions and generates significant cash flow in the early years of ownership — turning 20–40% of property costs into immediate tax savings without any change in how you operate the property.
