A Marine Corps Sergeant, Paul holds both a Principal Broker license and a Licensed Contractor designation, and spent years in the field — flipping over 150 homes in just four years and leading ground-up multi-family development projects. Having personally leveraged cost segregation since 2018 to accelerate returns on his own portfolio, Paul co-founded Seneca to make this powerful tax strategy accessible to investors at all levels — at an affordable price, delivered on time.

Cost segregation in New Jersey is an IRS-compliant tax strategy that involves an engineering-based study of your real estate property to reclassify building components into shorter depreciation categories — 5, 7, or 15 years — instead of the standard 27.5 or 39 years. This accelerates your depreciation deductions, significantly reducing federal taxable income. Given New Jersey's high property values and tax environment, cost segregation can be especially impactful for local investors.
