R.E. Cost Seg 2026 Review: Details, Pricing & Features

R.E. Cost Seg Overview

R.E. Cost Seg is a nationwide, engineering-backed cost segregation provider and technology platform serving real estate investors, property owners, CPAs, tax advisors, and portfolio operators. Its platform supports the full study workflow, including savings estimates, proposals, property intake, document collection, collaboration, study tracking, and report delivery.

R.E. Cost Seg centers its cost segregation offering around two primary products: Rapid Report and Fully Engineered Study. Rapid Report is the more streamlined, lower-cost option for qualifying properties, while the Fully Engineered Study provides a more comprehensive engineering analysis for commercial, larger, renovated, or more complex properties. Investors can use R.E. Cost Seg directly for their own properties, while CPAs, tax advisors, and other professionals can use the Advisor Portal to manage cost segregation studies across multiple clients. 

That two-product structure gives R.E. Cost Seg a relatively broad addressable market. Owners of qualifying residential properties may use Rapid Report, while larger residential, commercial, mixed-use, heavily renovated, and more complex properties can use a Fully Engineered Study.

Pros Explained

Two study options for different property needs: R.E. Cost Seg centers its offering on two primary products: Rapid Report and Fully Engineered Study. Rapid Report provides a streamlined, lower-cost option for qualifying properties, while the Fully Engineered Study offers a more comprehensive engineering analysis for commercial, larger, renovated, or more complex assets.

Specialized, nationwide cost segregation expertise: R.E. Cost Seg specializes in cost segregation and serves investors across all 50 states. Its focus on property-level depreciation analysis, combined with virtual inspections where appropriate, makes the service accessible across a wide range of residential and commercial real estate.

Integrated platform simplifies the process: R.E. Cost Seg’s platform centralizes estimates, proposals, property intake, documents, collaboration, study tracking, and final reports. Investors can also involve CPAs, property managers, and other stakeholders throughout the process.

Competitive, relatively transparent pricing: R.E. Cost Seg publishes starting prices for its primary study options, giving investors a useful benchmark before requesting a proposal. Rapid Report offers the lower-cost entry point, while Fully Engineered Studies cost more to reflect the additional engineering work and property analysis involved.

Strong tools for advisors and repeat users: The Advisor Portal gives CPAs, tax advisors, family offices, and other professionals a centralized way to manage multiple clients and studies. Proposal generation, study tracking, team access, and co-branding make the platform particularly useful for professionals who regularly recommend cost segregation.

Cons Explained

Rapid Report has eligibility requirements: Rapid Report is designed for smaller residential properties of up to four units, where each unit is under 3,500 square feet, with a depreciable basis under $1.2 million and capital improvements under $50,000. Owners must also complete a detailed property questionnaire, so properties outside those parameters or those requiring deeper analysis may need a Fully Engineered Study. 

Fully Engineered Study pricing varies: Fully Engineered Studies have published starting prices, but final costs depend on factors such as property size, type, renovations, and complexity. CRE owners with larger or more complicated assets will need a property-specific proposal to determine their actual cost.

Cost segregation isn’t right for every investor: The value of cost segregation depends on factors including property basis, taxable income, holding period, and the investor’s broader tax circumstances. Investors should weigh the expected benefit against the study cost and consult a qualified tax professional before proceeding.

Key Features

Rapid Report

Rapid Report is R.E. Cost Seg’s streamlined cost segregation product for qualifying properties. Instead of requiring a traditional engineering inspection, the process relies heavily on detailed property information the owner provides.

R.E. Cost Seg uses the information provided through the questionnaire in its modeling process, with an engineer reviewing the inputs and depreciation allocations before the report is completed. 

The tradeoff is straightforward: clients take on more data-gathering responsibility in exchange for a lower-cost, more streamlined study process. For eligible rental and investment properties that do not require the depth of a Fully Engineered Study, Rapid Report provides a more accessible entry point into cost segregation.

Fully Engineered Study

The Fully Engineered Study is R.E. Cost Seg’s comprehensive option for all residential and commercial properties that require deeper analysis, with no published maximum property value. They are also appropriate when greater property-specific detail and engineering depth may improve the result⁠.

The process combines property documentation with engineering review and a guided site inspection. Virtual inspections are typically conducted through a scheduled video call, during which an R.E. Cost Seg specialist guides the client or on-site contact through the property to document relevant components and conditions. In-person inspections are available when the property or study scope requires one.

Reports and CPA-Ready Deliverables

Completed studies include a detailed cost segregation report documenting the property analysis, asset classifications, recovery periods, and depreciation allocations. R.E. Cost Seg also provides an Excel fixed-asset schedule that the client’s CPA or tax professional can use when implementing the study on the tax return.

Clients can add their CPA to the process to review the results and ask technical questions about the study’s methodology or classifications. For qualifying look-back studies, R.E. Cost Seg also offers optional Form 3115 preparation and Section 481(a) adjustment support. The taxpayer and tax professional remain responsible for reviewing, signing, and filing the applicable tax forms.

Cost Segregation Calculator

R.E. Cost Seg provides an online cost segregation calculator that investors and advisors can use to estimate a property’s potential accelerated depreciation and tax savings before ordering a study. Users can begin with a property address, review available third-party property data, and adjust assumptions when the information does not reflect the property’s actual basis, renovations, or features.

The calculator estimates how a property’s depreciable basis may be allocated among shorter recovery periods and shows the potential effect on depreciation over time. Where applicable, it can account for renovations and qualifying components such as flooring, appliances, and other short-life assets. Results are preliminary estimates rather than final study conclusions, tax advice, or guaranteed savings.

Advisors can use the calculator to identify potential opportunities and explain the projected benefit to clients. Through the Advisor Portal, estimates can also be exported as branded PDFs for client discussions. This gives investors and their advisors a practical way to assess whether the likely tax benefit may justify the cost of a full cost segregation study.

Advisor Portal

The R.E. Cost Seg Advisor Portal is a self-service platform designed for CPAs, tax advisors, family offices, and other firms that manage cost segregation studies across multiple clients or properties. It brings client management, savings estimates, property intake, study ordering, billing information, progress tracking, and completed deliverables into one centralized platform.

Advisors can use the built-in cost segregation calculator to estimate a client’s potential accelerated depreciation benefit and export a branded PDF for review. They can also create studies directly, send clients secure questionnaire links, monitor each engagement from intake through delivery, and manage team access through role-based permissions. These features reduce the need to coordinate each study through separate spreadsheets, forms, and email threads.

The portal can be customized with a firm’s logo, brand colors, and other client-facing elements. Firms can use a fully branded experience while R.E. Cost Seg provides the cost segregation expertise and study support behind the scenes. Prepaid study credits and other volume-based options may also be available for qualifying high-volume partners.

For advisory firms, the main benefit is scalability. The portal allows a team to identify cost segregation opportunities, launch and track studies, and maintain visibility across its client book without building an internal cost segregation operation. Clients receive a more cohesive experience, while their CPA or tax advisor remains involved throughout the process.

Collaboration and Document Management

Clients can upload property documentation and invite other stakeholders into the process. This can include CPAs, property managers, project managers, and colleagues who may have information necessary to complete the study.

For CRE investors, that functionality is particularly useful because tax, accounting, asset management, and property-level responsibilities frequently sit with different people.

Audit Support

R.E. Cost Seg includes audit support with its primary study offerings, including written responses to questions related to the engineering methodology, asset classifications, and conclusions in its reports. The support does not include representation before the IRS or other taxing authorities. 

User Experience

R.E. Cost Seg’s platform creates a guided workflow for completing and managing cost segregation studies. Users can estimate potential savings, submit property information, upload documents, collaborate with CPAs or other stakeholders, track study progress, and access completed reports in one place.

Rapid Report requires more hands-on input because the owner completes a detailed property questionnaire, while the Fully Engineered Study shifts more of the analysis to R.E. Cost Seg’s team. For advisors managing multiple clients, the Advisor Portal provides additional tools for proposals, study tracking, team access, and client management.

Customer Support

R.E. Cost Seg combines its online platform with access to cost segregation specialists throughout the process. Clients can get help selecting the right study, submitting documentation, coordinating inspections, and answering questions about completed reports.

The company also works with clients’ existing CPAs and includes audit support with its primary study offerings. This provides additional assistance if questions arise about the engineering methodology or classifications used in a report.

Pricing

R.E. Cost Seg has two primary products with different pricing structures:

• Rapid Report: Starts at $950 and is designed as the lower-cost option for qualifying properties.
• Fully Engineered Study: Starts at $2,320 for residential properties and $2,730 for commercial properties, with final pricing depending on the property’s size, type, renovations, and complexity.

For qualifying look-back studies, R.E. Cost Seg offers optional Form 3115 preparation and Section 481(a) adjustment support for $600 per property. The service helps clients and their tax professionals implement missed depreciation without amending each prior-year return where the applicable rules allow. R.E. Cost Seg prepares the form, supporting statements, attachments, and adjustment calculation; the taxpayer and tax preparer remain responsible for signing and filing.
