Well, I don't know about streetwalkers, but, I do know about Home Inspectors. I would make a much better one than most out there, and I even climb roofs. I wouldn't pay for one, unless, I was standing right there every inch of the way, making sure he checks this and that; and not slack off. I am not saying they all do, but, I know I had paid for one, whom I call, Harvey the blind inspector. He came recommended by his son, who taught him everything he knew. He was great, his dad was not, and I gather he was not a very astute learner. And, he was expensive, not cheap, like a two-cent hooker. I wouldn't hire one, I think it is a waste. Take the money you would had spent and buy a book, read it, study it and find out what to look for yourself. Then, you got a few extra sheckles to make a few repairs. I think, that will put you ahead of the game. And, whatever you do, don't use the ones realtors will give you. If you must have one, ask another neighbor, or a friend or trusted relative.
