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).

Signs sound offensive to “guests”.

No offense.

This duty requires the landlord to evict a tenant who is guilty of an offense in the landlord's judgment. 

He is not sure now as it has not been resolved (offense was in October 2015), but his attorney believes it will be misdemeanor as it is his first offense.

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...

That,s where, and no offense to your Parents, hiring a PM company would have resolved your problems in maintaining the property and dealing with the town. why not see if the tenants can afford to buy it?

That is borderline harrassment and might be considered worse than the smoking offense in the first place.

And the FHA statement just slams the door on the newb status, no offense.
