Out-of-state landlord: best method to handle maintenance requests?

[Kelsey Vander Meulen]

I currently own a SFR in Houston which is managed by a property management company. But I recently purchased a triplex in Tucson, Arizona, which I plan to manage from out-of-state. I currently live in the Los Angeles metro area. I'm already using RentRedi to screen tenants, receive rent, deliver messages, but I wanted to know if anyone had any suggestions on either a software or virtual assistant type platform that helps them automate maintenance requests...
