Are You Going to Take a Few Quick Photos of the Common Areas, or Do a Thorough Full Condition Report for the Owner?
See the question "why might my home visit be expanded?" for a lot more detail.To summarize, if we arrive and the home is in great shape, 99% of the time we snap a few very general photos of the interior, do a thorough exterior report because that helps tie the owner to the reality of normal wear and tear, and then we're on our way.
A very convenient process for all. In offices where we have a full operations division they'll even be offering small free services like an HVAC filter or bulb change. That will one day be standard procedure and is being tested now.
All home visits run the risk of being expanded if we find photographable problems in the initial areas we check. For example a wet spot in the living room ceiling is often coming from the primary bathroom sink, and we would need to go through that room and spend time in the bathroom cutting off the water. Or simply hunting for whatever is above the water spot so we know what vendor to dispatch.
A good way to avoid a surprise is to thoroughly report anything along those lines to your account manager, with great photos, well before the scheduled day.
