Qualification equals income = 3x rent, credit 650+, no housing court issues, no violent crimes. 

Assuming, everything else is great for a tenant.I'm only in the prequalification stage right now and I will get more info after a full screening, but I'm tempted to say yes if it was:1) 7 years ago2) non-violent3) not repeatedJfyi, here is my current felony policy, courtesy of @Marcia Maynard:Criminal offenses (misdemeanor or felony) of a violent nature against person or property will result in denial.Applicants with a pattern of multiple offenses will be denied regardless of what the employment, credit and rental history shows.Applicants with a non-violent criminal misdemeanor that occurred more than two years ago or a non-violent criminal felony that occurred more than five years ago may be considered if restitution for their crime was made in full and all time was served.

I've had others in the past that have had to be evicted, for various reasons, just as with other tenants; the prospect of losing a voucher isn't sufficient motivation for some to pay on time, care for the premises or not try to move in the drug dealing boyfriend or the violent baby-daddy that breaks windows throwing hammers (that one broke her windshield, too).

No violent criminal history ever.

C = lower middle class housing, more multi-family mixed in but decent places, some crime but low-level stuff nothing dangerous or violent.

Out of the 77 communities in Chicago, the Chicago Tribune ranks it as the 9th most violent.

So check the median income per person, unemployment, single mother prevalence, racial diversity, vacant property rates and property and violent crime.

Someone is going to get violent.

I stay away from areas that have excessive violent crime, and areas that aren't close to freeways or employment centers.  

Something that started with this a couple of years ago (my house on the right)Has turned into the removal of the fence separating the two properties (by the owner of the truck) which leaves me losing the foot of space between the privacy fence and the boundary fence.Mitigating circumstances - the guy that owns the truck has a history of violent crime (kidnapping, sexual assault on a child, assaulting a police officer, etc., etc.) and my interactions with him have resulted in schizophrenic ramblings (i.e. the Vatican owns my property, all financial transactions are routed through the city of London, etc.)I spoke with an attorney from this forum (a terrific help) earlier this week and I am weighing my options...the best being a 4 foot retaining wall along the property line with a 6 foot permitted fence to the front of the house.
