Our Methodology

Why use cost segregation?

Our software compares your building to similar buildings from thousands of our past fully engineered studies. It then applies historical average values for 5-year personal property, based on the criteria you enter. The 15-year site values are calculated based on site size which factor in building type as well as location. Once your criteria is analyzed, your custom values are calculated. After you make payment, your custom report is sent to you by email or is available by direct download as a PDF.
