Properties we study
Different properties.
Different details.
A rental house and a commercial investment need different levels of review. We establish the scope around your property, its records, and the detail needed for a thorough analysis.
Residential
CommercialCommercial properties
Individually scoped studies for commercial real estate. Property use, construction detail, and available records guide the analysis and delivery plan.
Short-term rentalsFrom a single rental to $5M+
Short-term rental investments, including larger and commercial Airbnb properties above $5 million. Complex properties receive a tailored scope and quote.
What cost segregation looks for
One building.
More than one kind of asset.
A purchase price brings many components together. A cost segregation study looks at those components individually and documents their appropriate classifications.
1
The building itself
The structure and building systems form the starting point for the analysis.
2
What’s inside
Items such as qualifying finishes, fixtures, and equipment are reviewed for their use and classification.
3
Outside the walls
Site improvements, such as paving and landscaping, are considered separately from the building.
Illustrative only. Actual classifications depend on the property, asset use, and applicable rules.
THE STUDY PROCESS
From property records
to a complete report.
You should know what you’re ordering before the work begins. We confirm the records needed, the scope, the fee, and the expected delivery date. Then we document the analysis in a report you can keep and your tax preparer can review.
We review the property
Purchase records, property details, and improvement history establish the starting point for the analysis.
We confirm the scope
We review the records, identify anything missing, and confirm pricing and timing for the property.
We prepare the study
Our analysis separates qualifying assets and documents the cost allocations and depreciation classifications.
You receive the report
You receive the asset schedules and supporting documentation, ready for your tax preparer to review and apply.
WHAT STANDS BEHIND THE REPORT
Inside your study.
You receive more than an estimate. Your completed study includes asset schedules, cost allocations, and the methodology behind them. If you or your tax preparer have questions about the report, our team can help explain the analysis.

Questions after delivery? We’re here to help explain the report.
What does the completed study include?
Asset classifications, cost allocations, depreciation schedules, and documentation supporting the methodology. Your tax preparer reviews the report and determines how the deductions apply to your return.
Do you work on commercial and larger Airbnb properties?
Yes. Alongside residential rentals, we take on commercial properties and larger short-term rental investments, including properties above $5 million. Scope, fees, and delivery timing are confirmed individually.
How long will my study take?
Standard residential studies target two business days after complete intake and payment. Commercial and complex properties have an agreed timeline based on the scope and available documentation.
Does the calculator work for every property?
The instant calculator is a residential screening tool. Commercial, hospitality, and complex properties need an individual review. An estimate is not a completed study or a determination of the deduction you can use.
