This is the biggest mistake many potential new homeowners make when purchasing a home. Although the person you are considering may be very skilled, they are not trained or experienced at professional home inspections. Professional home inspection is a unique skill like no other. Professional inspectors get what we call an inspector’s instinct for problems. That instinct takes extensive training and lots of experience doing inspections to develop. Many contractors, and other trades professionals hire a professional home inspector to inspect their homes when they make a purchase.
