A whole stream of events issues from the decision, raising in one's favor all manner of unforeseen incidents and meetings and material assistance, which no man could have dreamed would have come his way.

The fine details of each incident will make the difference. 

There isn't really any one incident that I can point to.

to protect my interest from this tenant in the middle of term of lease because of recent eviction incidents. 

I'm finishing up a property this week and was a full remodel...baring a freak incident there shouldn't be any capital expenses for at least 7 years with most 15-20 years out.

Also, how much liability coverage do you have per incident/property?

., it was running constantly for who knows how long); left house unlocked multiple times;  left sliding glass doors to an unconditioned sun room with a poorly lockable storm door and the AC running full blast in the house;  had 2 guys in non-smoking unit of a triplex claim to be the new tenants and sit in the unit smoking pot all day... did not find out until after the fact when property management contacted me about the key being stolen from the lock box (I guess a following viewer couldn't get in) and the upstairs tenants told me about the pot incident when I checked that out;  had a house rented out from under me via craigslist even though there was a sheet explicitly stating 'you can't rent this property from craigslist' posted on the wall. 

The PM advised that it may take about a week for me to get it.A few hours later I hopped on crimereports, and didn't see any incidents at the property.

Age and time heal a lot of behavior issues, were they 22 years old and was an incident 20 years ago or was it last year and the guy is 54? 

You need to have a serious talk with them about the incident and how it makes everyone feel at risk.Tell him he is responsible for the conduct of his "friends" and will be ask to leave if anything else happens again.If he balks at that,evict him now and get better sleep at night for everyone else involved.
