Thanks guys. I’m still going through internachi training to become a CPI. When I’m finished, I’ll be starting business offering only ancillary services to other home inspectors and realtors. I will start with only 1 service. I’m deciding between, radon, sewer scope, mold testing, or maybe infrared scanning. Whatever I choose I'll be getting the appropriate training to use it. Which of these would you guys recommend? I'm in Utah BTW.
