It goes on and on... for instance, I'm now automating door locks, lights, and cameras with smart technologies.

Add cameras way up high.

I'm usually by myself, so I put my magnetic "realty services" sign on my vehicle & walk around carrying a clipboard & camera, no one has approached me about trespassing yet.

Spray exterior heavily with pesticide to prevent bugs.Seal doors and windows, put up a few cheap Wal-Mart game cameras to keep an eye on the property until new tenant arrives.

The best part is with the security camera you probably got a good look at their faces! 

One thing to keep in mind is that the local agent is only contacted in the event that someone makes a complaint to the township about your rental, so if you screen your guests and use cameras/Noise Aware, you will likely be able to avoid your local agent being contacted. 

I now get a notification when the cleaners and hot tub maintenance complete the post stay tasks (previously I would have to check the cameras).This sounds like I didn’t like hospitable, which isn’t true.  

Put up cameras on the perimeter of the property as well as No Trespassing/Security Cameras on Property' signage.  

We use Ring Doorbells and Cameras for our STR in Vermont.
