I have calculated an average of around 20% of gross rent in repairs, credit losses, and other miscellaneous losses from the building getting raided by police to burning down garages and many other crazy things.

This is a first for us, so I have a few questions.Since the police were called and a police report filed, do we press charges or get our attorney involved?

I have friends that are police/fire/ems there and I hear a lot of stories.  

Have them call the police. 

Police are just people, and people make mistakes.

Any time you have to "police" some situation, it will be a hassle and stressful and just not worth it.Think in terms of being an applicant looking to rent the property. 

I am not sure. but after the closing it is 100% your property, can you call police to get him out?

Your tenant can file an incident report with the police department.

We informed the police of what we knew and they eventually busted everyone in the unit and cleaned it out for us! 

I have properties in NC, SC and one in NYC the one i would like to bring up is in SC I bought a fourplex all rented leases in place BUT all four leases were cheep the apartments all looks like Vietnam going through the DMZ bombing raid. so I sent all 4 tenants a 30 day notice that they are to move within 5 days after each lease has ended we rehabbed the entire building as each one left pulled the carpet and got started. we have now finished half the building invested about $30k and re-rented the two finished apt's each went up by $250 a month plus pet dep and extra rent for the pets. and this took all the RIF RAF out and even got a thank you note from the local police and the mayors office for what we did. now in saying all this SC is VERY, VERY Landlord Friendly no rent by the 5th pay $40 bucks for first notice to pay or remove no rent still they have 10 days to pay or leave after that 14 days later the sheriff;s office removes the tenant and retake possession.
