To do what I think he is doing you would need unrestricted building access, a plausible reason to be on-site at irregular hours, and a cover that does not require you to interact with residents or explain your presence. Property management covers all three. It is a functionally perfect cover for anyone who needs to move through a building without drawing sustained attention, because residents expect to see property managers and have been conditioned not to ask questions when they do.

I do not have the lease records. I do not have proof of who manages this property or whether the management company is real or is a shell. What I have is the observation that the company name on his clipboard is printed in a font that is slightly too small for the page and the logo is not centered. I noticed this on the third occurrence when I was close enough to see it. That is not how professional property management companies print their forms. That is how someone prints a form when they are producing a prop and they are close enough to the real thing not to bother perfecting the details.

The question I keep coming back to is what, specifically, they would be watching for. There are several possibilities and I have ranked them by likelihood given the other documentation on this site. The man on the footage, the three missing minutes, the diagram in the glove box — each of these is a separate thread and none of them are connected to this building except by my presence in it. That is the connection. The target of the watching is not the building. The target is whoever is doing the documentation.
