Interesting post. I could not imagine dealing with Realtors or brokers that much. All my area Realtor boards prohibit them from being present, even if the buyer shows up. I have never (knock on wood) had an instance where I felt uncomfortable being there as the office sets it up and warns the seller of my inspection time. I had a new Realtor show up at the same time and I had to tell them to call their office to see if they are allowed to be here with me. They were not and had to explain to the buyer why they had to leave. Liability scares them. I have a keybox key and always call ahead to verify it was confirmed.
