We list a brief qualification criteria in our rental ads which includes 3 times the monthly rent, have no evictions, clean background check, no violent criminals, and have good credit history and 650+ credit score.I have seen examples of Adverse Action Notices that list a bunch of check boxes for reason of denial such as Unable to verify required minimum income, eviction filing or judgement, no credit file, criminal record, delinquent past or present obligations, does not meet minimum required Credit Score etc.

Not doing so can be criminal.
