Quick Answer
- Cost segregation studies range from $795 to $15,000+ depending on property type, size, and provider
- Traditional engineering firms: $3,000–$15,000, 4–8 week turnaround
- Automated engineering-based providers: $795–$6,995, delivered in under an hour
- Most residential properties produce 40x–95x ROI on the study cost
A cost segregation study typically costs between $795 and $15,000, depending on the property type, size, and provider. Traditional engineering firms charge $3,000–$15,000 and take 4–8 weeks. Modern automated providers deliver the same engineering-based methodology for $795–$6,995 in under an hour. The difference in cost is driven by delivery method—site visits, manual engineering hours, and scheduling overhead—not the quality of the underlying analysis.
This guide breaks down what cost segregation studies actually cost across property types, what drives the price variation, what you receive for that investment, and when the study cost isn't justified by the tax savings.
Pricing by Property Type
The table below shows typical pricing ranges across the market. The left column shows what you'll pay with an automated provider like CostSegSmart. The right column shows what traditional engineering firms typically charge for the same property type.
| Property Type | Automated Provider | Traditional Firm |
|---|---|---|
| SFR / STR / Condo (under $1M) | $795 | $3,000–$5,000 |
| SFR / STR ($1M–$2M) | $1,295 | $4,000–$6,000 |
| SFR / STR ($2M+) | $1,495 | $5,000–$8,000 |
| Multifamily 2–4 units | $995–$1,695 | $3,500–$6,000 |
| Multifamily 5+ units | $1,495–$5,995 | $5,000–$10,000 |
| Commercial | $1,495–$6,995 | $5,000–$15,000+ |

What Drives the Price Difference
The single biggest cost driver is whether the provider requires a physical site visit. Traditional firms send one or two engineers to the property for a half-day or full-day walkthrough. That means travel expenses, scheduling coordination, and 8–16 hours of on-site labor before the engineering analysis even begins. This alone accounts for $1,000–$3,000 of the price difference. It's worth noting that the IRS Cost Segregation Audit Techniques Guide does not require a physical site visit. It requires detailed observation and documentation of building components, which can be accomplished through satellite imagery, street-level photography, county assessor records, and engineering cost databases.
Property complexity and size also matter. A 2,000 SF single family rental has roughly the same building systems as every other 2,000 SF SFR—the component library is well-established and the analysis is straightforward. A 50,000 SF mixed-use building with ground-floor retail, upper-floor offices, and structured parking has fundamentally different systems on each floor, requires separate analyses for each use, and produces a longer, more detailed report. The engineering work scales with complexity, which is why commercial pricing ranges are wider.
Turnaround time is a secondary factor. Traditional firms operate on a queue-based model: your property enters a backlog, gets assigned to an engineer, goes through review, and ships in 4–8 weeks. Some offer "rush" delivery for an additional fee. Automated providers eliminate the queue entirely. The analysis runs against the same RSMeans cost databases and IRS classification rules, but the engineering logic is systematized rather than performed manually for each property. The result is delivery in under an hour, at a fraction of the cost.
Finally, the level of ongoing support varies. Some traditional firms include a certain number of hours of audit support in their pricing. Others charge separately. At CostSegSmart, every study includes Form 3115 documentation and audit-ready methodology documentation as part of the base price.
What You Actually Receive
Regardless of price point, a legitimate cost segregation study should include the same core deliverables. Here's what's in the 30+ page engineering report you receive from CostSegSmart.
Your CPA receives everything needed to file. There's no additional engineering work required on their end—the report is structured so they can map the depreciation schedules directly to the tax return. For a detailed walkthrough of what a finished report looks like, see our $750K Airbnb example or $500K rental example.
ROI Reality Check
The economics of cost segregation are unusual because the study cost is relatively fixed while the tax savings scale with property value. This means the ROI gets better as the property gets more expensive, and it's positive for virtually any property over $200K.
$750K Furnished STR
$500K Unfurnished Rental
Even at the high end of traditional pricing ($5,000 for a residential study), most properties produce 10–30x ROI. The math works because accelerated depreciation shifts real dollars forward: you're not creating new deductions, you're taking deductions you're already entitled to and concentrating them into Year 1 instead of spreading them over 27.5 or 39 years. With 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act, every dollar reclassified into a shorter MACRS class is deductible immediately.

When the Cost Isn't Justified
Cost segregation doesn't make sense for every property
Properties under $200K. On a $150K rental, the depreciable basis after land allocation might be $120K. At an 18% reclassification rate, that's roughly $21,600 in accelerated deductions—producing about $5,400 in tax savings at a 25% bracket. A $795 study still has positive ROI, but the absolute dollar savings may not be worth the effort of filing the amended depreciation schedules, especially if your CPA charges separately for the additional work.
Very low tax brackets. Cost segregation creates deductions, and deductions are only worth your marginal tax rate. If you're in the 12% or 15% bracket, the same reclassification that produces $75,000 in savings for a 37% bracket taxpayer produces $24,000–$30,000 for you. Still positive ROI on the study itself, but the complexity-to-benefit ratio changes.
Short holding periods with recapture risk. When you sell a property, depreciation taken in excess of straight-line is subject to recapture under IRC §1245 and §1250. If you plan to sell within 2–3 years without a 1031 exchange, the recaptured depreciation may reduce or eliminate the net benefit. This doesn't make cost seg "bad"—it's a timing difference, not a permanent loss—but it changes the math enough that you should model it with your CPA first.

Frequently Asked Questions
For a single family rental or short-term rental under $1M, a cost segregation study typically costs between $795 and $3,000. Traditional engineering firms charge $3,000–$5,000 because they include a physical site visit and manual engineering analysis. Modern automated providers deliver the same engineering-based methodology—RSMeans cost data, IRS-compliant MACRS classification, 30+ page reports—for $795, with delivery in under an hour instead of 4–8 weeks.
Yes. The price difference between a $795 study and a $5,000 study is driven by delivery method, not quality. Traditional firms charge more because they send engineers on-site, which adds travel, labor, and scheduling overhead. Modern providers use satellite imagery, county assessor data, and engineering cost databases to perform the same component-level analysis remotely. The IRS Cost Segregation Audit Techniques Guide does not require a physical site visit. Both approaches produce detailed engineering reports with component-level MACRS classification, depreciation schedules, and audit documentation.
Most residential cost segregation studies produce 30x–95x ROI. A $750K STR with a $795 study cost typically generates $50,000–$75,000 in Year 1 tax savings from accelerated depreciation. Even a $500K unfurnished rental produces roughly $27,000 in savings (34x ROI). At the high end of traditional pricing ($5,000), most properties still produce 10–30x ROI. The economics work because the tax savings scale with property value while the study cost stays relatively fixed. See the calculator for your property's specific estimate.
