Make sure you have lots of liability insurance and focus on running a great business; the incidence of actual suits is miniscule.

As a PM, I text/email/call owners any time there is a big issue and send them an incident report or some kind of maintenance documentation.

They had a real falling out with their landlord and refused to return her calls after the incident.

Next, I would call the real estate commission and report the incident, see if they just moved or where they are.

I would not do it.Had a realtor tell me of an incident she had with an other client, on a 500K+ property her buyer gave a leaseback. 

You can also request an incident report, if one was written using the FOIA form.

These were incidents in different states in the past 12 months.

After the incident in San Diego, I turned off to real estate, but I soon realized that it was an expensive lesson none the less.

Ok, another situation has surfaced from this incident.

i almost did. i had a roof leak and shingles were bad. i called them and they said my deductible was $2500 and it would have cost much less to fix. so i didn't do it. to be honest, i dont like a deductible that high. it means that besides a catastrophic incident, i'd not file a claim for anything else. even a burned kitchen might not be worth it.the other thing i didn't like is that it took a few calls to understand what the process is. i had to talk to the manager since i was not getting a call back from the agent i had worked with.
