Just for grins I started hanging out on the HACHI web site and I took the test. For $350 I could have been a HACHI "certified" Home Inspector. The "test" was a joke and some of the "right" answers were wrong. The working Home Inspectors there were asking the same kinds of questions people ask here and getting a lot of bad answers. Bear in mind, people were paying these guys. The strange thing is, when Florida started licensing Home Inspectors, just waving that $350 HACHI certification. Even with that license, here are a few things the HI missed at my kid's house.
