Honestly, I'm not going to try and stereotype all home inspectors here (some are actually really good), but most home inspectors I've met and seen are a lip service to the buyers and don't generally find anywhere near the faults of a home. If you have any sort of basic home maintenance and a little construction experience, you can do very good inspection on your own. Ask a friend or family member who knows more about the subject.
The terms of my last home sale had a licensed home inspector. I purposely 'showcased' several errors for them, and they zero of them. I had an entire illegal garage that was completely missed, not to mention an illegal electrical service (can't have 2 overhead services to one residential lot here), improper fittings on the gas lines, mold around the bathroom (minor really), and many plumbing issues.
Not the first time I've seen this either. 10 years in construction and this is all too common to hear from homeowners.
I ended up with nearly three decades in the business, and I can't disagree at all. The inspector that posted here is a bit unusual, in highlighting the conflict between the real estate industry and the inspection industry. The bottom line for most inspectors who rely on the R.E industry for work, is that they are whores who manage to keep their pants up, yet still get paid well for screwing you.
I too have seen criminally negligent work for many of these guys, to the point that they wrote and told the homeowner flat out lies to make the deal happen. I only sell my own properties under one condition, when it comes to home inspections. The buyer is welcome to get one BEFORE we sign a contract. There are no inspection contingencies is any document I will ever sign, and I warn the buyer that I have little patience or time for any snivelly B.S. from any inspector that came "highly recommended" from their realtor, but I will quickly address any issues that are discovered by a legitimate professional. (which is not an issue, since I don't have anything to hide in the first place)
As to the OP, there are times when the right inspector can be valuable, and this may be one of them. Before the boom collapsed here, we had one inspector who used to give realtors the shakes. He refused to do business with any of them, and wasn't shy about calling most of them the incompetent varmints that they are. He would spend 4-5 hours tearing through a house like a Jack Russell trying to excavate a chipmunk from a hole. When he handed you the report, you knew ever dark secret of the place, and how long you could expect every single system and finish to last. That's a guy who earned my respect and was worth twice what a realtor's whore charges. If you can find a guy like that, you might be forever in debt to somebody who headed you away from a disaster, or found you the great diamond in the rough. Good luck.
