Why Segonomics
Built for residential rentals and short-term rental investors. Fast, flat-fee, and filed straight to your CPA with audit protection included.
Audit-Ready Reports
Every study follows IRS guidelines and the Cost Segregation Audit Techniques Guide. Your CPA gets a full MACRS classification they can file and defend — not a spreadsheet with "estimates" in the header.
2 Business Days, No Site Visit
Intake takes five minutes. Your completed report is in your CPA's hands within 2 business days — no scheduling, no appointments, no engineer walking through your rental.
Deductions That Move the Needle
Residential rental owners typically recover $20,000–$80,000 in first-year deductions. For short-term rental investors who meet the average-stay and material participation rules, those deductions can offset W-2 and business income.
How It Works
Four steps from submission to a deduction your CPA can file.
Submit Your Property
Five-minute online form. Basic property details, purchase info, and whatever photos and closing docs you already have.
We Analyze
Engineering team classifies every component by IRS recovery period — 5, 7, 15, and 27.5-year assets broken out and documented.
Report Delivered

Claim Your Deductions
Your CPA uses the asset schedule on Form 4562 to accelerate depreciation — often tens of thousands in year one.

What’s Included
Flat fee, everything bundled. Traditional cost seg firms charge $5,000–$10,000 for the same deliverable.
Typical first-year deductions: $20,000–$80,000. Short-term rental investors who qualify for non-passive treatment often apply those deductions directly against W-2 or business income.

Common Questions
What property types qualify?
Residential rental properties up to 4 units — single-family homes, condos, townhouses, duplexes, triplexes, fourplexes, and short-term rentals (Airbnb, VRBO, Booking.com). The property must be held for rental or business use.
Does this work with the short-term rental tax strategy?
Yes. For short-term rentals with an average guest stay of 7 days or less where the owner materially participates, the IRS treats the activity as non-passive. Cost segregation and bonus depreciation can then generate first-year losses that offset W-2 or business income. Your CPA confirms whether you qualify; we provide the asset classification that makes the deduction possible.
Is this IRS-compliant? What if I'm audited?
Every report follows IRS guidelines and the Cost Segregation Audit Techniques Guide. Audit protection is included — if you're audited, we provide the supporting documentation and respond to the taxing authority's inquiries.
Do I need a site visit?
No. Our process is fully remote. We use the photos you submit combined with public records, MLS data, and satellite imagery. No appointments, no engineer walking through your rental.
