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? 

I got in touch with a contact at the police dept yesterday to look into the owners... 

I put them out at night and its usually me and police doing their rounds.

Not that you are the morality police, but you don't want non-paying guests hogging the shower and laundry facilities.There is a LL on the Mr.

Plus the property is located in lower income area but it right across from the police station.

I have a tenant who lives on one of these "warzone" streets and she complains about how dangerous the neighborhood is--but whenever she elaborates, it turns out she is actually complaining about a constant police presence breaking up rowdy teenage parties.

Key things to note are noise violations and "red tags" (if police respond to a party complaint and have to shut it down).
