Merle Rosskam

CEO
Cost segregation for RV parks is an engineering-based tax strategy that identifies and reclassifies property components such as utility hookup pedestals, paved roads, fencing, lighting, and recreational structures from 39-year depreciation into 5-, 7-, or 15-year schedules. This accelerates your tax deductions significantly, often generating tens of thousands of dollars in first-year tax savings and improving overall cash flow for park operators.
