Engineering-Based Studies

Each study uses component-level analysis, basis reconciliation, documented assumptions, and technical support for material classifications.

💰

Property-Specific Analysis

Identify the actual components that may belong in 5, 7, and 15-year recovery periods rather than relying on a generic reclassification percentage.

🚀

Clear Scope and Timeline

Know which records are needed, what the study will cover, and the expected delivery schedule before the analysis begins.

🛡

Documented Methodology

Every Stratum study includes comprehensive documentation, component photographs, and engineering methodology that is designed to support review by the owner’s tax professional.

How Cost Segregation Works

A documented process from property records through tax-advisor implementation.

1. Property Analysis

Share your property details, closing statement, and photos. We evaluate whether a cost segregation study makes financial sense for your specific property and investment strategy.

2. Engineering Study

Our team conducts a detailed component-level analysis, identifying and reclassifying building components into shorter MACRS recovery periods (5, 7, and 15-year property classes).

3. Deliver Your Report

You receive a report with asset classifications, depreciation schedules, supporting records, and assumptions for your tax preparer to review and implement.
