Random squatters are much more rare than local transients or neighbors. I have had to deal with only a few over the last 3 years. They were mainly for long term vacancies, with exception of one.
The first time was 2012 when I dabbled at buying a rental. I closed on a nice house in a B to B+ neighborhood in Ontario, CA. I got the keys from the agent and went to the house to walk it. There was a guy locked in the garage. After a brief engagement, he ran off with his skateboard and never came around again. He was 20-something, likely from the neighborhood. It could have been deadly, but I never broke snap/leather. I stopped carrying 99% of the time after that because I had been out of the army a dozen years already and it too close for comfort.
Next was 2021, when I decided to take REI seriously. Upon closing escrow on a small apartment, I removed 2 transients from an ajointing lot, because they were encamped against the back wall of my parking garages. This was a C- neighborhood. I gave him and his buddy 30 minutes to clear out. One moved slowly than the other. 60 minutes later, I took all items that was left around and trashed it. It was A LOT. The next night, while at the property to let the tenants know I was the new owner, I noticed he was in the community laundry and with his phone plugged, a bottle of piss on the floor, and looked like he was going to sleep in there. I confronted him and he stated I owe him for throwing away his family possessions. I disagreed. Long story short, I put my binder down, told my wife to hold my phone and stand back. Business was settled inside the laundry room and he was removed off the property. The next night, the door to the laundry room was kicked in and no one would admit to witnessing anything. I drove around the neighborhood and found the corner where my new transient friends had relocated/encamped. After a brief engagement, they understood never to come around that building again.
I yanked a few others out, with less physical force, but I knew the risks. I have towed many cars off my properties and had to keep tow drivers safe while they do their service.
There has been a nice lull for a bit. But this past 12 months, I had 3 incidents at the same house, because it was vacant for many months awaiting repairs and inspections. I do not deal directly with it much anymore and I have a local employee that takes care of they business. He tossed out a strung out 20 year old blond that was in the shower on the last occasion. Problem solved.
Moral of the story, regardless of neighborhoods, empty homes draw attention and there are a lot of people looking for shelter. As you grow, it will happen and you just need to deal with it and move forward. Some LL may never know the work it takes by PMs to keep properties from squatters.
I feel I got lucky because it happened to me starting out and I figured that's normal. After being on this forum, I'm willing to bet it's not and many on here would not be able to quickly/efficiency clear out or not let it impact their future REI efforts.
