A full engineering-based analysis of your townhouse that reclassifies assets into 5, 7, or 15-year depreciation schedules, delivering average first-year savings of $171,243 with IRS-compliant documentation and audit defense included.
Already own your townhouse? Claim missed depreciation from the past 15 years without amending prior returns. Using IRS Form 3115, we recover all overlooked deductions in a single tax year.
Skip the scheduling hassle with our convenient 30–45 minute video call inspection. Our engineers conduct real-time component identification for your townhouse, delivering results 2–3 weeks faster than traditional on-site visits.
Every townhouse cost segregation study includes our Seneca AuditDefense guarantee—comprehensive IRS audit representation at no additional charge for the entire duration of your property ownership.
Our team works directly with your accountant to review findings, implement depreciation schedules, and ensure seamless integration of cost segregation benefits into your annual tax strategy.
Beyond cost segregation, we identify additional tax-saving opportunities across your entire portfolio—at no extra charge—helping you unlock maximum value from every property and business asset you own.
We begin with a no-cost analysis of your townhouse to assess eligibility, estimate potential tax savings, and provide a transparent breakdown of costs and projected ROI. Most townhouse owners qualify if their depreciable building basis exceeds $300,000.
