Choosing the right cost segregation approach depends on your property type, renovation history, and the level of precision you want in your analysis. Today, investors have access to several tiers of studies DIY, Engineer Reviewed, and Fully Engineered, each designed for different levels of complexity and investor needs.
Each approach has a purpose. A small Airbnb property might benefit from a quick, automated study, while a large apartment complex or mixed-use building may require an in-depth engineering analysis. The key is aligning your property’s characteristics with the right study type to maximize depreciation benefits while staying compliant.

The Fully Engineered cost segregation study offers the highest level of detail and accuracy. It includes a white-glove intake process, a virtual or in-person site inspection, and a comprehensive engineering analysis tailored to your property.
If your property has a basis above $750k, includes unique amenities (such as a guest house, movie theatre, or boat dock), or you’ve completed major renovations, this method typically delivers the greatest depreciation benefits and strongest IRS defensibility.
Advantages
- Engineer-led process with virtual or in-person inspection
- Most comprehensive and defensible report type
- Audit protection included
- Required for complex or multi-phase projects
Fully engineered studies are often the best choice for long-term investors, multifamily operators, and those preparing for potential IRS review.
This type of study is also required if you’ve completed major renovations, as it allows separate depreciation schedules to be properly assigned to each improvement project.
How to Decide Which Study Is Right for You
