A full engineering-based analysis that reclassifies your single-family home's components into 5, 7, or 15-year depreciation schedules—delivering average first-year deductions of $171,243 and ROI ratios of 10–25:1.
Claim missed depreciation on single-family properties placed in service up to 15 years ago—without amending prior returns. We use IRS Form 3115 to capture all unclaimed deductions in a single tax year.
A convenient 30–45 minute video call inspection replaces costly on-site visits, reducing study costs and delivering completed reports in just 2–3 weeks—no disruption to your schedule or tenants.
Every study includes Seneca AuditDefense at no extra charge—lifetime coverage for the duration of your property ownership, with full IRS communication handling and a potential study-cost refund if a material issue arises.
Post-study support ensures seamless integration with your CPA or tax preparer. We coordinate directly with your accountant to implement depreciation schedules and Form 3115 filings accurately and efficiently.
Beyond cost segregation, our team provides additional complimentary tax assessments across your full portfolio—identifying further savings opportunities from properties, partnerships, businesses, and assets.
We start with a no-cost consultation to assess your single-family rental's eligibility, provide a preliminary savings estimate, and give you a transparent breakdown of expected costs and projected ROI—so you know exactly what to expect before committing.

Yes, cost segregation absolutely applies to single-family homes—provided the property is income-producing (a rental or investment property, not a primary residence). The study reclassifies components like flooring, appliances, landscaping, and specialty wiring into 5, 7, or 15-year depreciation schedules instead of the standard 27.5 years, generating significant front-loaded tax deductions.
