AHhhh...! There's the rub. I've been a Realtor for 50 years, used to run my own brokerage in Wisconsin for 20+ years before relocating to CA. I'd follow around the best home inspector I knew as he checked furnace, basements, electric etc. I was probably a PITA, but I learned a LOT! In CA, as in many places I'm sure, the agents do not accompany the Home Inspector for an hour or two as they do their inspections, and so those agents miss out on a bunch of knowledge that would help them help their clients. The Home Inspector I used wouldn't give a cost to repair, but he would tell me generally what the issue was so I could follow up with the best problem-solver. It was very helpful and educational. Unless agents have been in the biz for a long time, I'll bet they haven't invested time in gaining that kind of knowledge. Their client is their pocketbook in most cases, despite what their license says.
As I am basically starting from scratch over here in switching back to sales, I am once again sifting through service providers to add to my "stable" of problem-solvers. I doubt 90% of agents do that on their own here; often they rely on referrals from within their sales office. Unfortunately, my broker's focus is primarily on commercial, so he has little to offer on the res side. On the good side, he pays me a good split and is not a control freak, and doesn't require office meetings, tours etc. On the bad side, I'm basically on my own, like when I had my own brokerage years ago, but without the management responsibilities.
