Then the sheriff (police) will remove the tenant within 24 hours from the date you file an eviction.  

that's why your tenant has car insurance,, they should call police and issue a complaint,, none of your concern just pass the info on to them. 

I went back to my room and called the police, and the officers came by and told her not to talk to me anymore.

Now the police are calling me and telling me to change the locks and board up the one window which is busted, since I am not the owner yet, am I legally allowed to do so..??

I had a tenant recently leave because they are noisy in the middle of the night and the previous tenant had filed a police report for stolen packages.

By doing that the city makes money fining you for the violations that they would fix, police the property more to add to violations while its being rehabbed, and knows that you better do it by the permit book. 

Just ONE street over (the end of the block) starts a whole new area where crime is still an issue, police walk the streets 24/7, the homeless are seen sleeping at every corner, etc.

Also many misbudget things like police details (no flagmen in boston) if they need street or sidewalk shutdowns etc. 

I mean, why not be an insurance agent, mortgage broker, an attorney, a chef, police officer, etc?
