We told them each that if it was that bad that they needed to call the police and send us a copy of the police report.

Not to mention their employment options would be limited and I wouldn't want any risk of the police tearing up my house because they were serving a warrant for his 3rd felony.

The police told my tenant that I would have to press charges but when I contacted the police they informed me the people did not break the law.

I let them know that those are not appropriate calls at that time of night (call the police if they are a noise nuisance). 

One of the investor talked to an attorney and even lodge a police report, but no one seems to be able to help.Does anyone of you have similar experience, or have any suggestion?

I will repair a damaged entry door/hardware at my expense with a police report, otherwise I will repair and bill the tenant. 

The police officer gave my dad his card and wrote "heroin overdose" on the card with reference to a case number.  

As for monitoring the parking, I would not be able to self police the parking situation.  

If there is drama (relationship issues impacted work performance, restraining orders, police reports) in their life before the divorce then the divorce will be a wild ride and you might be in for some challenges.

This simplifies the landlords responsibilities as it requires the collective to police the payments.
