Property Manager Interview Questions and Screening Process

[Billy Zhao]

It seems that every successful real estate investors say that an effective property manager is the key. And yet, I haven't seen a comprehensive metrics to measure what makes a PM better. I've seen countless anecdotal evidence of a bad PM. 

I was thinking that I need a standard to screen for a good PM. Perhaps starts with asking for references from other real estate investors who used the same PM, and maybe a list of interview questions to see if the PM answer them correctly. 

Are there any such metrics that exist? Or should I compile one and share it with everyone?
