Paul Spies is a Marine Corps Sergeant whose discipline and precision define Seneca's engineering-based approach to cost segregation. With over 8 years of hands-on real estate construction experience, Paul has flipped more than 150 homes in 4 years and led ground-up multifamily development projects as both a Principal Broker and Licensed Contractor. He began using cost segregation personally in 2018 and quickly recognized that most real estate investors—including those across South Carolina's growing markets—were missing out on a powerful, IRS-approved tax strategy. He co-founded Seneca to democratize access to high-quality cost segregation studies at an affordable price, delivered on schedule. Paul's boots-on-the-ground construction background ensures every study reflects real-world property realities.
A cost segregation study is an engineering-based tax analysis that reclassifies components of your real estate from 27.5- or 39-year depreciation schedules into shorter 5-, 7-, or 15-year categories. This accelerates your depreciation deductions, reducing taxable income significantly in the early years of ownership. The study involves a property inspection, engineering analysis, and delivery of IRS-compliant schedules your CPA uses directly in your tax return.
