Paul Spies brings a rare combination of military discipline, construction expertise, and real estate investment experience to Seneca Cost Segregation. As a Marine Corps Sergeant, Paul developed the leadership and precision that now defines Seneca's engineering-based methodology. With over 8 years in real estate construction, a Principal Broker license, and a Licensed Contractor designation, he successfully flipped over 150 homes in 4 years and led ground-up multi-family developments. Having personally leveraged cost segregation since 2018 to accelerate his own investment returns, Paul co-founded Seneca to make the same powerful tax strategy accessible and affordable for property owners across Massachusetts and the entire country — delivered on time, every time.
A cost segregation study is an engineering-based tax analysis that reclassifies components of your real estate from the standard 27.5- or 39-year depreciation schedules into shorter 5-, 7-, or 15-year categories. This accelerates your depreciation deductions, significantly reducing your taxable income in the early years of ownership. Massachusetts property owners typically see first-year savings ranging from $30,000 to several million dollars, depending on property size.
