Regular check-ins with your GC will help keep everything on track.

You can check the events forum here for ones near you, meetup dot com, and also your local REIA to get started.

I recommend checking out Roommates.com, SpareRoom.com, and Roomster.com.

Make sure you’re checking in on your tenants, getting them to document any damage, and having solid insurance coverage.

That seems like a good feature, I will check them out.

I'm diving into some of the public county-level Zillow data.

Just to give further data to the equation. 

If we do everything correctly and we screen carefully (credit check, employment verification, etc.), what would be the worst-case scenario?

Agents may also have macro data on historical data, local median sale prices, absorption rate, etc to help with your analyses and projections.Networking/build a team: Attend local meetups, virtual meetups and stay active on forums like this.A lot of this will be done in front of a PC unfortunately but if you cut out the noise, you'll be able to maximize your time.Lastly, something that has helped me tremendously with respect to focus and improving efficiency is the pommodor technique. 

Usually I have also checked for disqualifying content on social media accounts.
