The home inspection business is perfectly suited for some people, but not for others. Find out if your state has laws that regulate home inspectors.
Every state is different, and laws are constantly changing.
Some states have very strict training and experience requirements, while most states have no requirements at all. Contact the department in your state government that issues occupational licenses, ask them if they have any requirements for home inspectors, and if so, to send you that information. If you can't find any information there, at least you can get the phone number of the proper state department to call. I'm a contractor who knows houses inside and out. If your state does NOT regulate home inspectors, and you are experienced and confident in your home construction background, then this book may be all you need.
