My bookkeeping firm provides me with a steady active income, which allows me to keep doing deals, cover unexpected expenses, and navigate the occasional black swan event.

"I am no lawyer, but terms of service are occasionally challenged & found insufficient.  

If you have an older home that requires a lot of maintenance, you probably want to avoid the manager who charges a markup.I recommend shopping around occasionally to see if your PM is procuring fair pricing or just marking you up to make money without justification.As for expectations, you need to read the PM agreement and understand what is charged and why.

In addition to their standard updates, I appreciate the regular calls with a supervisor to address any issues with our rep and make sure everything is on track.They've managed several of my properties, and while there were occasional maintenance costs, I felt they were reasonable and necessary to keep the properties in good shape and avoid bigger issues down the line.

Police drive by occasionally and see 3-4 people standing outside smoking. 

Again not a big deal for a home owner with one single mortgage to keep track of if their loan changes services occasionally, but with a number of loans all changing companies multiple times in the same year, it becomes frustrating trying to keep track of all of these changes, only to have more changes.   

The only concern we run into is occasional foundation issues near the river, towards the south east side of town.

Maybe that occasional outreach is helping us over time as well?

Across ten doors I've had three turnovers in five years and one of the ladies that moved out (she wanted a larger house) still calls me occasionally to see if I have something available again. 

I do occasionally post about it on some of the social media sites for travel nurses, such as Travel Nurse Gypsy Housing for example.
