Sometimes I think we forget who we represent and where our best referrals come from. It well may be the agent's job to make sure the house is open for the inspection, but I promise you if the client drives 60 miles for an inspection, he isn't going to care who screwed it up or how. If we make an appointment, we need to be sure we can honor it. It's our client for the inspection, not the agents. I never trust an agent to show up. I either have a lockbox key, a lockbox code or I insist on picking up a key in advance of the inspection. If the agent won't cooperate, I ask the client for some assistance. When possible I drive by before the inspection to be sure the agent hasn't taken the lockbox off the house, oir removed the key. Some do as soon as an offer is accepted. There isn't any way for the client to predict what an agent or his/her office might do after the offer is in place. Most agents don't even rememeber what they did. When they get the offer, they go shopping and totally forget the client and the house (some exceptions apply. If you disappoint you inspection client, no matter who is at fault, you will lose the chance for future referrals. If you save the day, you will almost certainly get referrals....and you won't be hassled about your inspection. The client won't listen to a bad word about your work. Give it a try.
