Very few, if any, inspectors are “tied in” with real estate agents. However, as with all people, real estate agents get comfortable with home inspectors. Just like you do with your auto mechanic, the grocery store clerk, your dry cleaner, barber, etc.
Usually what differentiates a home inspector with real estate agents is how the report is written, how the inspection is conducted, how the inspector talks and intereacts with the client, even what kind of vehicle the inspector drives and how the inspector dresses.
I don’t put pictures in the report just for the sake of putting pictures in the report or proving to someone that I know how to use a camera, how to take pictures, and how to put pictures in a report.
I have seen reports that had 200 pictures in them, of everything from the chipped sink basin, to peeling paint, to a torn screen. I only put pictures in the report if the problem was somewhere I went that my client didn’t, like up in the attic or under the house, or if what I’m talking about doesn’t have a layperson’s term, like a TPR relief valve on the water heater.
Many of my condo reports have no pictures because many of the condos here don’t have attics, don’t have water heaters, don’t have laundry rooms, etc.
If you have any concerns with your specific inspector, though, call him/her and discuss your concerns with the inspector.
