Top Remote Cost Segregation Study Providers In 2027

Compare 10 remote cost segregation providers for 2027, from video-inspected engineered studies to a cost segregation study online, with prices and turnaround.

Remote cost segregation has moved from a workaround to the default for many investors. Instead of waiting for an engineer to fly in, owners now send closing documents, photos and floor plans, or walk a specialist through the property on a video call. For most residential rentals and many smaller commercial buildings, a virtual cost segregation study is enough to support a well-documented file.

This list is for investors who own property far from where they live, owners of short-term rentals and small portfolios, and CPAs looking for providers that can work without a site visit. We compared how each provider gathers property data (documents only, guided video or a scanning kit), published pricing, turnaround, the level of engineering or specialist review, and audit support. Some providers below are full engineering firms with a remote option; others are built to deliver a cost segregation study online from start to finish. For a side-by-side of the delivery models, read in-person, virtual or software cost segregation.

The rule to know for 2027: the One Big Beautiful Bill Act, signed July 4, 2025, permanently restored 100% bonus depreciation for qualifying property acquired after January 19, 2025. That makes the short-life components a study identifies more valuable in year one. Property under a binding contract signed before January 20, 2025 follows the older phase-down. Confirm the details with your CPA.

Best Remote Cost Segregation Study Providers In 2027

1. R.E. Cost Seg — Engineered Studies With A Smartphone-Guided Virtual Inspection

R.E. Cost Seg built its process around remote work. Its Fully Engineered Study includes a 30 to 60 minute virtual inspection, where someone with access to the property guides a site visit specialist on a smartphone video call. In-house engineers, CPAs and cost segregation specialists then build the study, and several professionals review it before delivery. Residential studies start at $2,320 and commercial at $2,730.

For simpler residential properties, the Rapid Report starts at $950, uses an online questionnaire and documents with no inspection, and arrives in about 5 business days. The firm reports more than 20,000 completed studies, includes written audit support at no added cost, and offers in-person visits for an extra fee when a building needs one.

Best for: Owners who want a fully engineered study with a documented inspection, without anyone traveling to the property.

2. Cost Seg Smart — Online Studies From $495 With 1 To 2 Day Delivery

Cost Seg Smart runs most of its studies remotely, using your documents and public records, and adds a video walkthrough or an in-person visit where a property calls for it. Residential pricing starts at $495 for single-family homes, condos and short-term rentals under $300,000, multifamily and standard commercial start at $995, and most residential studies arrive in 1 to 2 business days.

Each study includes a 40-plus page CPA-ready PDF, an Excel fixed-asset file, CPA coordination, unlimited revisions to the original study and lifetime written audit support. Form 3115 preparation is an add-on. For commercial properties of $3 million or more, the firm brings in a credentialed engineering partner, and it declines some specialty commercial work where on-site engineering judgment matters, which is a reasonable line to draw for a remote model.

Best for: Residential and small commercial owners who want a cost segregation study online at a low, published price.

3. Virtual Cost Segregation — Completely Virtual Engineered Studies At $2,200 Flat

Virtual Cost Segregation does not do site visits. After booking, you email documents and photos, and a US-based engineering team builds the study using cost data from sources including RSMeans and Craftsman, following the IRS Audit Techniques Guide. Completed reports arrive in 3 to 5 business days.

The price is a flat $2,200 per study, or $1,980 per property for three or more. That fee includes audit support, CPA support, Form 3115 catch-up filings, assessor land-value lookups, renovation invoice review and free revisions within a week of delivery. It works on residential investment property: single-family rentals, condos, townhomes, short-term rentals and multifamily.

Best for: Residential investors who want an engineered study and an all-inclusive flat price without coordinating a visit.

4. Madison SPECS — Smart Tour Video Capture Guided By An Off-Site Engineer

Madison SPECS, part of Madison Commercial Real Estate Services and based in Lakewood, New Jersey, developed the Smart Tour process for remote studies. A person at the property receives a kit with video and digital equipment, and an off-site engineer guides them through capturing the building components.

The firm reports more than 40,000 completed cost segregation studies, a team of over 60 professionals including 20 in-house engineers, and clients in all 50 states. Its focus leans toward multifamily, commercial and industrial property, and pricing is quoted per property. The structured capture process makes it one of the few remote options built for larger buildings.

Best for: Multifamily and commercial owners who want engineering depth with minimal disruption to tenants.

5. Engineered Tax Services — Remote Studies From A Licensed Engineering Firm

Engineered Tax Services, headquartered in West Palm Beach, Florida, considers a site visit ideal but runs remote studies for less complex or smaller commercial properties. Remote engagements rely on client-supplied photos and video walkthroughs, plus floor plans and construction documents, and are also used where an on-site visit is impractical, such as multi-tenant buildings.

ETS describes itself as a licensed engineering firm specializing in tax strategy, with engineers, CPAs and tax attorneys on staff and offices in eight US cities. That gives remote clients the option to scale up to an on-site study, or to add 179D, 45L or R&D work, with the same firm.

Best for: Owners of smaller commercial buildings who want a remote study from a large engineering-led firm.

6. WeCostSeg — Virtual Or In-Person Studies With Five Years Of Audit Defense

WeCostSeg runs its analysis virtually or in person depending on the tier. You request a free proposal, sign the engagement letter, upload documents, and your CPA files once the study is complete. The Rapid Report starts at $795 for residential property under $800,000 of basis and is engineer-reviewed, with delivery in 5 to 10 business days.

Fully engineered residential studies start at $2,495 and commercial at $2,995, both with engineer-signed reports. Every tier includes five years of audit defense. It covers 14 property types, from short-term rentals and single-family homes to self-storage, hotels, medical offices and gas stations. It is a newer, founder-led company.

Best for: Investors who want remote convenience and multi-year audit defense in the base price.

7. Cost Seg EZ — Three Tiers From Instant DIY To Virtual-Inspection Studies

Cost Seg EZ, a sister brand of MVO Cost Segregation in Princeton, New Jersey, offers three remote-friendly tiers. The DIY study costs $595 and is generated instantly for residential property under $1 million. The Engineer Reviewed tier costs $895 and takes 3 to 5 business days. The Fully Engineered tier starts at $2,500, takes 3 to 4 weeks and includes a virtual or in-person site inspection with no purchase price limit.

Audit protection is a $195 add-on on the two lower tiers and is included with the engineered study. The company says it has completed studies in all 50 states over the last 20 years.

Best for: Owners who want to choose how much engineering they pay for, while keeping the whole process remote.

8. CostSegregation.com (KBKG) — Self-Guided Online Reports Backed By KBKG

CostSegregation.com is KBKG’s self-guided platform. You enter an address, AI pulls public property data, you can invite your CPA, and you download the report. KBKG says eligible properties can get a full report in under 15 minutes. It supports residential and commercial property up to $1.5 million of building basis, excluding land.

Residential pricing is listed at $495 for a $750,000 tax basis and commercial at $1,295 for a $1,000,000 basis, and you can try it free and pay only if the results make sense. Every report includes audit support and up to five corrections. KBKG, founded in 1999, handles properties above the software limit with its professional team.

Best for: Investors and CPAs who want a fully online report with a long-established firm behind it.

9. RentalWriteOff — $899 Flat-Fee Remote Studies For 1 To 4 Unit Rentals

RentalWriteOff is fully remote with no site visit. You submit property information and photos, often from an appraisal or rental listing, and the team analyzes the data and identifies components for faster depreciation. The fee is a flat $899 per property, delivery is about 2 business days after complete intake, and Form 3115 for eligible look-back studies is included.

It covers residential property up to four units, including single-family homes, condos, townhomes, small multifamily, short-term rentals and mobile homes. Each study gets an expert quality check before delivery, audit support is included, and some CPA partners deliver its reports under their own brand.

Best for: Small residential landlords who want a simple, flat-fee remote study with look-back filing included.

10. Abode Cost Segregation — $481 AI-Generated Studies For Short-Term Rentals

Abode Cost Segregation is built for Airbnb, VRBO and vacation rental owners. You answer property questions in a few minutes, its AI classifies components, and the study is generated in minutes. Deliverables include a PDF report, an Excel fixed asset schedule, Form 3115 catch-up guidance and land versus building documentation, for a flat $481 per property.

Abode is clear about its limits: no engineering firm or site visit is involved, it recommends CPA review before filing, and it does not offer audit defense or IRS representation. There is a 90-day refund on the fee. For a simple short-term rental where cost is the main concern, that tradeoff can be reasonable.

Best for: Short-term rental hosts with straightforward properties who are comfortable relying on their CPA for any IRS follow-up.

How To Choose A Remote Cost Segregation Provider

How Will They See The Property?

Remote providers gather data in different ways: documents and public records only, photos you submit, a live video walkthrough, or a scanning kit. The more complex the building, the more direct evidence you want in the file.

Who Signs Off On The Study?

Ask whether an engineer prepares or reviews the classifications, or whether the report is model-generated. Both can be appropriate, but you should know which you are buying.

What Is Included In The Price?

Compare Form 3115 preparation, revisions, rush fees and audit support. A low headline price can rise once add-ons are counted.

Does The Property Fit Their Model?

Most online tools cap eligibility by basis or property type. Hotels with heavy food service, manufacturing plants and ground-up construction usually need a deeper engagement. See our list of commercial cost segregation firms for those cases.

Frequently Asked Questions

Does The IRS Accept Cost Segregation Studies Done Without A Site Visit?

Cost segregation without a site visit is common. The IRS looks at the quality of documentation and methodology. A site visit is considered best practice, but remote studies supported by photos, video, plans and cost data are widely used for simpler properties. Your CPA can advise on what level of support suits your situation.

How Fast Can I Get A Cost Segregation Study Online?

Self-guided and AI-assisted tools can produce a report in minutes. Specialist-reviewed remote studies typically take 1 to 10 business days, and fully engineered remote studies take 2 to 4 weeks.

Are Remote Studies Good For Short-Term Rentals?

They are a common fit, since many short-term rentals are single-family homes with clear documentation. Read our list of cost segregation companies for short-term rentals for providers focused on that market.

Conclusion

Remote cost segregation now covers a spectrum, from AI-generated reports for a few hundred dollars to engineered studies with live video inspections. Pick the level of evidence and review that matches the property, compare what audit support really includes, and confirm your CPA is comfortable with the deliverable.
