Derogatory implies a more abhorrent behavior in my opinion. 

We have a no eviction or criminal record so it makes it really easy!

What if a foreign national on a work visa wants to rent from you and he's unable to pass a credit check or criminal background?

I get what Adam was saying, i.e. quit wasting time on unproductive behavior, and I would agree with that, but everyone has to have an outlet and something "fun" to do.

Anyway, I'm not going to defend criminals or fraudsters, but you're totally wrong on housing values.I find your use of scare quotes condescending.

As for the eviction purpose, even if it's in your lease (eviction for illegal activites), you'll need to prove "the seriousness" (couple criteria) of the problem and give him notice to correct his behavior. 

I know fighting mice is tough going. especially if behavior encourages it.

And I'm not too proud to ask for advice, so here I am :) I do have hardlined "principles" for denial for some items like felonies, evictions, and income, but credit is a gray area for me.Anyway, I have an applicant that I get a good gut feel from, has no criminal history, has no evictions, and the pay stub indicates the income is 4.5x the monthly rent.

Anyone having tenancy in the unit, over age of 18 is screened, criminal background check per person is what your looking at,,if one of them don't meet criteria then you have to reject the application..Credit wise you combine the 2 incomes to see if they meet the credit criteria,, one may have good credit / income,, one may not... but combined they still would need to meet the criteria set.A person, even a child is a tenant,, they are listed on lease as minor child , date of birth.If your criteria is 2 people and the couple has a child,, then they would not qualify for the unit they are OVER occupancy.. 

IF HE STEALS THEM THEN HE'S JUST ELEVATED HIS PROBLEMS TO NOW A CRIMINAL OFFENSE, DINGED HIS LICENSE AND HIS BUSINESS WITH A CRIMINAL ACTION AGAINST HIMSELF AND BUSINESS.
