I did one just yesterday morning, although not new, I’m “new” relative to the other inspectors in my region. With that said, I’ve never found them to be embarrassing, awkward, or a waste of my time. For every 10 realtors that are afraid you’re a deal killer, you’ll find one that values your expertise and looks forward to the information you have to provide at an inspection, as it’ll help them negotiate the best and fairest deal for their client.
I don’t look at them as much of as a presentation, as much as a conversation. Depending on the audience and size you’re speaking to this can be difficult, but often I don’t find it to be more than 15-20 people. You’re the authority, you have questions you can answer, you can offer them your services and what makes you better. Deal Killer or not, there are two ways to present your information to the client, one is in person, on is the report, from there you can present it any number of ways. I’ve been with many inspectors and in many cases its the objectivity that goes out the window, and those are the deal killers. But I digress, just focus on what you have to offer, not what you don’t, and include them in the conversation.
