Choosing a cost segregation firm: the 10 questions that actually matter

SegWise publishes starting prices — 10% below the published fees of the national rapid-delivery firms: SegWise Rapid from $855 (questionnaire study for small rentals), SegWise Quick™ from $1,499 (24-hour engineered delivery), and our Full Engineered Study from $2,088 for residential and $2,457+ for commercial properties. Final pricing depends on property size, type, and complexity, and you get a flat quote — typically the same business day — before any work begins. Industry-wide, engineering-based studies commonly run $3,000–$15,000+.

For most properties with at least $250K of depreciable basis, yes: first-year tax savings typically run many multiples of the study fee (our case examples range from 10× to 90×), and you can quantify it before you spend a dollar using our free calculator and free written proposal. If the math is thin for your property, we tell you — not every property justifies a study yet.

No. Studies can be done retroactively to the year you placed the property in service. Missed depreciation from prior years is claimed as a one-time "catch-up" deduction on your current return by filing Form 3115 — you do not amend prior-year returns. Most owners have been on the standard 27.5/39-year schedule, so the catch-up is often the single largest deduction they have ever claimed.
