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.  

You might not, but you can't count on it.In the United States, a first offense fine is $16,000 per discriminatory event.  

I notified a potential tenant via text that their application was denied after the $35 tenant screening service revealed an active, open bankruptcy (<6 months) (as well as two prior dismissed bankruptcy filings), a recent eviction filing and judgment (<6 months), two collection actions, and a prior but old criminal conviction (non-violent offense).

Falsifying information is a pretty serious offense. 

In any prosecution (for trespass) under RCW 9A.52.070 and 9A.52.080, it is a defense that:(1) A building involved in an offense under RCW 9A.52.070 was abandoned; or(2) The premises were at the time open to members of the public and the actor complied with all lawful conditions imposed on access to or remaining in the premises; or(3) The actor reasonably believed that the owner of the premises, or other person empowered to license access thereto, would have licensed him or her to enter or remain:Second,  abandonment can be implied.  

I will rent to previous criminals but I try to protect myself too, The offense needs to be 7 years or older, I only do month to month lease, all other screening must be spot on though...good credit, refernces, etc...

As someone who is disabled, whose income, at this time, is derived from a government program, I find the statements of certain posters to be not only extremely prejudicial but ignorant, uneducated, and blatantly offensive.

And Elizabeth, I do have a smoking charge of 50$ for first offense and eviction for second in my lease.  

No offense folks, but Rick is the only one with some common sense here.

So no intents or offense should be taken.
