You can also contact the city or county police to report an abandoned vehicle.

We collected over 20 applications at the open house.We ended up having to serve another tenant a 60-day notice after several domestic disputes where the police (and in one case fire department) were called.

Tell him to call the police and/or get a protection order on them. 

Not having a Property Manager for low end rentals makes as much sense as not having police officers because the speed limit signs are posted on the highway.

I have met and worked with a Pinkerton a descendant of the famous pinkerton agency, and at the same place I worked with a Hatfield a descendant of the famous Hatfield/McCoy fued,  She told me the story long before it came out on the history channel. been on tv in a show by Andrew Zimmerman the guy who eats weird food. 

There is an interesting quote from the Chief of Police up in Longmont (I live in Denver too), "For 80% of the calls we receive, people do not need a uniformed officer, they need a neighbor."

I called 911 and Police arrived but due to these lax Texas laws towards the tenant, they could not offer any help.

Courts suspended evictions but a judge can still have a police officer accompany you to the property.

So I was at my unit today and the neighbor told me that the police knocked on her door a few days ago because they had knocked on the door to my building and no one answered.

Also with her help you can screen her through the police department in the local jurisdiction where she is from.
