Self-managing rentals from out of state

[Grace A.]

Landlords who self-manage rentals in a different state. How do you this? What systems do you use to oversee the listing, showing, and managing repairs, inspections etc.? How do you mitigate the risks of not being close by if anything happens?
I’ve read landlording on autopilot and out of town landlord but I’d like to hear from people who actually do this, how you do it and any pitfalls to watch out for. 
Thank you
