Frequently Asked Questions

A cost segregation study breaks down the components of your property into different IRS asset categories. Instead of depreciating your entire building over 27.5 or 39 years, certain components (like appliances, cabinetry, flooring, fencing, and landscaping) can be depreciated over 5, 7, or 15 years. With 100% bonus depreciation now available, you can deduct these reclassified amounts entirely in Year 1, dramatically reducing your taxable income.
Just the basics: property address, purchase price, acquisition date, square footage, and year built. Our smart intake form guides you through everything — it takes about 5 minutes. No site visit required. You can optionally upload property photos, your closing statement, and tax assessment for even more accurate results.
Yes. Our studies follow the IRS Cost Segregation Audit Techniques Guide and include all 13 principal elements the IRS looks for. We use the same engineering-based methodology and cost databases as traditional firms. We recommend having your CPA review the report, and we include comprehensive audit documentation with every study.
Reports are prepared after you submit your property details and payment. Studies are typically delivered in under 1 hour. Complex or large commercial properties may take up to 24 hours. Compare that to the 4-8 week turnaround from traditional cost segregation firms.
FF&E stands for Furniture, Fixtures & Equipment. For STR investors, this includes beds, couches, dining tables, TVs, rugs, wall art, coffee machines, patio furniture, linens, and small appliances. These are typically 5-year depreciable property (some items are 7-year), and with bonus depreciation they can be 100% deducted in Year 1. STR investors often spend $20K–$80K furnishing a property — our FF&E analysis ensures you capture those deductions instead of spreading them over 27.5 years.
It depends on your participation. If you materially participate in your STR (the IRS uses a 100-hour / 750-hour test for short-term rentals), your rental activity is not treated as passive — meaning the losses can offset your W-2 or other active income. This is one of the most powerful tax strategies for STR investors. We recommend discussing material participation with your CPA, and our reports include the depreciation schedules your CPA needs to apply these deductions correctly.
Absolutely. You can perform a "lookback" cost segregation study on any property you currently own, regardless of when you purchased it. The IRS allows you to catch up on missed depreciation deductions through a Form 3115 change in accounting method — and you don't even need to amend prior returns.
Typical ROI is 30x to 70x the cost of the study. For example, a $750,000 STR property might yield $188,000+ in accelerated deductions, resulting in $69,000+ in estimated first-year tax impact (at a 37% tax rate). Against a $795 study fee, that's an ROI of over 87x. Exact pricing is based on property type and purchase price.
No — we deliver a finished, CPA-ready study. There's no software to learn, no data to enter, and no guesswork on your end. You provide your property details at checkout, and we handle everything: engineering-based cost analysis, IRS classification, MACRS depreciation schedules, and a complete 35+ page report delivered to your inbox. Some companies sell DIY tools that require you to research and input your own property data. We do all of that for you.
