The building with the fire incident was condemned by the city!

They had charged me $65 for each maintenance incident, but after I contacted their help desk, they refunded me the charges since I had only owned the house for less than 3 months. 3) Upon a closer review, I realized they had been charging me 10% for property management instead of 8% per our contract since October.

As others have suggested, you could threaten to report the incident to the commission. 

It's your building, and this is a serious incident.

My guess is you would claim that as income and the cost of the repairs incurred from the incident an expense. 

Wait for itWait for itWait for itWait for itBecause, 7 years prior to this incident, there was a similar incidence on the property.I told my lawyer, that if they do not take us off the suit, we will countersue for our expenses. 

Yes I heard about that incident. 

I also once had a tenant in another property go through a domestic violence incident.

That would be way up with single incident of roof replacement or HVAC replacement.

Its too late to help with this incident but my advice is to only accept full payments in the future.
