The risk seems minimal as the offense is largely unrelated to his ability as a tenant.

Non payment is the same issue as far as eviction but as others eluded to , you can throw them out quickly without the hassle of an eviction for non lease offenses .

It's important to look at a nationwide report because they might have been convicted of an offense or be on a sex offender list in another county or state and you deserve to know that before renting to them.Another powerful screening tactic is to get an address history report so you can compare their actual residential history with what they claim on their application.  

Fee of $X for cleaning fee or HVAC filtration (if applicable) on first offense.
