Cost Segregation Review Methodology

We spend hours researching and evaluating each cost segregation company we review at Merchant Maverick, placing special emphasis on key characteristics to generate our service provider ratings.

When rating cost segregation companies, we use an 18-point rubric that looks at features, fees, customer service, and user reviews. We weigh each section differently to calculate the total star rating.

  • Features: 50% of the total star rating
  • Fees: 35% of the total star rating
  • Customer Service: 10% of the total star rating
  • User Reviews: 5% of the total star rating

Each section is further broken down into granular, weighted subsections, in which we look at specific attributes, like whether a free initial analysis is available, which cost segregation resources are offered, and availability in all 50 states.
