Seems like the more rural counties use this system?   

@Robert Schwenkler We set up those gaps, when needed, in our Property Management system.

Keep things as organized as possible too, so you don't miss anything and that will help create a system for future deals, making it easier each time. 

There are many buildings with systems reaching the end of their life - Galvanized hot water risers, leaking vent stacks, aging window systems, outdated elevator and fire safety equipment.

They will have systems in place for finding off-market deals for you to analyse where the numbers are more attractive.

Flipping system?

So my vote is for rentals.  

Hi - Any large property managers (50+ STRs) who manage properties for other owners, what is your most preferred PMS? What are its pros and cons for you?

Finding systems that optimize your time and efficiency with your rentals makes a big difference.  

You can buy something like a cheap Arlo camera system at Costco and pay for the Internet connection in one of your units.You could ask law enforcement to do routine drive-bys or safety checks.
