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.

No offense taken Joe, but thanks none the less!

Back ground check showed that he had a drunk driving offense 15 years ago, otherwise clear.She’s a little high maintenance, but for the most part I can calm her down over the phone.  

You are taking offense that someone has suggested you contact an attorney, but this is precisely what you need to do, and do it now.

I just got one - a father and son (and pregnant fiancee, God help her) duo - with 3 entire pages of  convictions and arrests (repeated offenses) for everything you can think of : burglary, assault with a deadly weapon, domestic battery, felony battery, drug possession, that's not even all of it.
