They let him go free, as all they did is respond to a 911 call for an "unresponsive person".

To be blunt, you're not a bad landlord because you neglected to take care of the property or were unresponsive (which seems to be your concern), you're a bad landlord because you let tenants walk all over you.2.

But how can you NOT be concerned about a company that has basically ignored and become unresponsive to their clients??

I was working with an agent (who is also a PM) for the last several years but had to part ways with her due to several reasons (unresponsive, lack of transparency, etc).

Nothing worse than someone who is unresponsive about your investment.

Late on payments, no receipts for the many repairs they claimed were necessary, unresponsive to calls and emails.

Is it the landlord "letting their tenants live" this way or is it the low-life, unresponsible tenants that create their environment?

If the AG is unresponsive you may get a quicker response from the local PD.

They are unresponsive on emails and their phone line is often busy.  

The property needs a fair amount of work, but I was able to get it for 10% less than a similar neighboring property that sold one month prior.The listing agent has been very unresponsive so far, and today I found out that he has not properly notified the existing tenants of their TOPA rights.
