Good responses on this thread. 

.- Urgent maintenance issues, this is the most tricky part, in my case I have 3 of these situation and the go-to contractor didn't even answer the phone, so I had to find someone else, so made many calls to get this sorted quickly.One of my investors lives in Chicago and found that the house was destroyed when the tenant left so his wife came to Dallas for 2 months to fix everything so they can put back in rent. 

I had some issue in the initial setup, but they were very responsive and worked quickly to get it resolved. 

Jason,Thank you for detailed response.

any tips / alternatives?
