If you screen your tenants properly with an application, credit report, criminal background check, etc. then you should be fine.

Then meet them there, show it and take an App if possible.Run Credit, Housing Court and Criminal.

Studied criminal justice but dropped out.

This is a REC matter, not a criminal matter.

I can already look up any criminal actions, including eviction on Lexis Nexis for about $7.

Go through each of the criteria to let them know what you will be checking for, if they balk at the prospect of you calling their employer or checking the criminal history, etc, they're probably not going to pay the application fee.I understand you're really asking about the gut feeling aspect but generally, if you have comprehensive criteria for tenant screening, chances are the tenant who doesn't meet your "gut" test won't meet at least one of your criteria. 

But I've never been challenged on it and my attorney doesn't seem too worried that I'm abusive about it, so I still have it in my lease that criminal activity - even without a conviction - may be grounds for termination.

My question is when will regulators put a stop to these licensed criminals?

There are two types of crooks on CL....local or cyber.  

I do not want to lie to them who I am if they are my potential tenants if I have to hold for a while.On the page it says "IT IS A CRIMINAL OFFENSE TO TRESPASS ON THIS PROPERTY"What should I do?
