Frequently asked questions

Everything you need to know about cost segregation studies.

How does a virtual cost segregation study work?

No site visit required, and the IRS doesn't mandate one. Our US-based engineers complete your study from property photos, purchase documents, and building records. These are the same inputs used in a traditional study. You upload your documents, we handle the analysis, and you receive a complete engineering report in 3 to 5 business days. No scheduling, no travel, no delays.

How long does a cost segregation study take?

Your completed study is delivered in 3 to 5 business days. Traditional firms often take 4 to 8 weeks. Once you purchase and upload your documents, our engineers begin analysis immediately. You'll receive a complete engineering report, formatted and ready for your CPA to use on your return.

What documents do I need to start a cost segregation study?

Not many, and we collect them by email after you book. First, a few details: the name or legal entity on the deed, whether it's a short-term or long-term rental, the date you placed it in service, whether you bought it furnished, and the tax year for the study (and whether you need a Form 3115). Then the documents: a closing document showing the purchase price and date (HUD-1, ALTA, or similar), the appraisal and inspection report from closing if you have them, and photos, ideally from the original listing or your Airbnb page, though recent photos work as a backup. No appraisal? We pull the county tax assessor's record. If you've renovated, add your invoices or receipts, the scope of work from your contract if you have one, and after photos.

Does a home inspection report help with a cost segregation study?

It does, more than most people expect. Photos show us what's in the property; an inspection report tells us what it is. Inspection reports typically list appliance and equipment makes, models, ages, and conditions, detail that photos alone don't capture. That lets us itemize more components individually instead of grouping them together, which moves more of your property's basis into shorter depreciation classes. It's not required, but if you have one from your purchase, it's the easiest way to get more out of your study.

What if I forget to send a document or photo?

It happens, and it doesn't cost you anything. If you realize after delivery that you're missing an invoice, a set of photos, or another document that could change your study, send it over within a week of receiving your study and we'll revise it at no additional cost. This comes up most often with renovations, where a contractor invoice surfaces after the fact, or with older purchases, where paperwork takes time to track down. We'd rather you send it late than not at all.

Does cost segregation increase my risk of an IRS audit?

Cost segregation is an IRS-recognized strategy with its own published Audit Technique Guide. When it's done right, using engineering-based methodology, proper documentation, and applicable law citations, it's a defensible position, not a red flag. Every study we deliver is built to that standard. And if the IRS ever asks questions, we provide full audit support at no additional cost.

What is bonus depreciation?

Bonus depreciation lets you deduct the full cost of qualifying short-life assets in the year a property is placed in service, rather than spreading deductions over decades. The One Big Beautiful Bill Act, signed July 4, 2025, restored 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025. A cost segregation study identifies which components of your property qualify, so you can claim the maximum deduction upfront.

When should I get a cost segregation study?

The best time is the year you place your property in service. That's when you capture the full benefit of bonus depreciation. A change in use, such as converting a primary residence to a rental, is another ideal trigger. But those aren't the only situations. If you already own investment property and never had a study done, you can still catch up on missed deductions. Your CPA can help determine the best timing for your specific tax situation.

Can I do a cost segregation study on a property I bought years ago?

Yes. This is called a look-back study. If you've owned a rental property for years and never had a cost segregation study done, you haven't missed your chance. We provide Form 3115 on request, the form your CPA files to claim the missed depreciation as a single adjustment on this year's return, with no need to amend prior-year filings. Your property doesn't need to be newly purchased. It just needs to be in service as a rental.

What is the minimum property value to make a cost segregation study worth it?

There's no hard rule, but the question is always return on investment. At $2,200 flat, the math works at lower property values than it does with firms charging $5,000 to $15,000. As a general guide, properties valued at $200,000 or more typically produce enough reclassifiable assets to pay for the study many times over in year one. Get a free estimate to see the numbers for your specific property.

How much can I save with a cost segregation study?

Results vary by property, but industry averages show that 20 to 45 percent of a property's value is typically reclassifiable to shorter depreciation schedules. These are assets that can be expensed far faster than the structure itself. At a flat fee of $2,200, most property owners recover the study cost in year one through tax savings alone. Your CPA can give you a precise estimate based on your situation.

How is the land value determined in my cost segregation study?

Land isn't depreciable, so separating its value from the building is the first and most consequential step in your study. It's also the number an IRS examiner is most likely to test. We use your closing appraisal when you have one, since it's direct evidence of value. If you don't, we pull the county tax assessor's record and apply its land-to-total ratio to your purchase price. Either way, your report shows which source we used, so the number is never a rule of thumb.

What property types qualify for a cost segregation study?

Any residential investment property used for rental or business purposes can qualify, including single-family rentals, multifamily buildings, condominiums, townhomes, and short-term rentals. The property must be held for business or investment use, not as a primary personal residence. If you're unsure whether your property qualifies, a free estimate is a fast way to find out before you commit.

Can I use cost segregation to offset my W-2 income with an Airbnb or short-term rental?

Short-term rentals with an average guest stay of 7 days or less are treated differently than long-term rentals under the tax code. If you materially participate in your STR, the IRS may classify it as a non-passive activity. That means losses can potentially offset your ordinary W-2 income. Cost segregation accelerates those losses significantly. How this applies to your situation depends on your specific circumstances. Your CPA confirms eligibility; we provide the study they need to act on it. Read more about how the STR loophole works.

What does my CPA do with the cost segregation study?

Your CPA uses the study to update your depreciation schedules, apply bonus depreciation elections, and file Form 3115 to claim prior years in one shot if you're catching up on a property you already own. Our reports are formatted to be CPA-ready. If your accountant has questions about the analysis, we're available to support them directly at no additional cost.

Do you offer discounts for multiple properties or portfolios?

Yes, and the rate is published. Study 3 or more properties and every study is 10% off, $1,980 per property instead of $2,200. Each property still gets its own complete report; you get one invoice and one point of contact. See portfolio pricing. Have an unusual mix? Tell us about the portfolio.
