Our PM mentioned that the guy has an drug offense from a few years back.

She's not a drug dealer, but she is receiving a very large divorce settlement, has no income, will be going to nursing school. 

The building is overrun with drug dealers, dope addicts and gang members.

Drug dealers move in-- doesn't matter, no one will want to rent your house, or you have to make it dirt cheap-- but you can't control stuff outside of your own house! 

Some things we have included that we have seen common include:Makes 3 times the amount of monthly rent paymentHas 3 or more good years of rental references Has no prior evictionsHas not made excessive late paymentsHave not filed bankruptcy or been foreclosed on in the last 5 yearsHas a good credit score (any one have any specific number they don't typically go below)Does not have any drug, violence, theft, fraud, capital or sex offender convectionsHas no breeches of leasesHas no history of damage to propertyMust be neat, clean, prompt and courteous Any one have any others they would add to the list?

You can report vandalism, vacant properties, drug dealing, potholes, broken streetlights, derelict vehicles, nuisance properties, loose animals, overflow of trash, etc.

What if your tenant starts dealing drugs? 

I KNOW a lot of people drink, use drugs, sit around and do nothing, but there are some people who just can't make it.

I give them a drug screen first, but that is another story.

If they have prior felony or misdemenor convictions in a list of areas (sex offenses, drug-related charges, dishonesty / fraud, violence, child or elder abuse) they are not qualified.
