One is a criminal action, the other civil.  

You can also limit based on credit score and criminal activity if you have a consistent written set of criteria.

I rely on the background checks to check for criminal activity and to see if they have had any evictions in their past, credit screening just tells me a bit about their spending habits.  

I just received my first applications back along with their credit/criminal history.

Then, you fail to check his criminal history, and he then wrecks your neighbor's windows in the property next door to the tenant.  

Not a fan honestly,I understand why, however I think prosecuting the people who left him there is really where the focus needs to be.

I am assuming you have done criminal background checks as well?  

. #1 it's illegal, if the tenant can prove what you did, you'll get sued at best, or maybe arrested for theft or criminal mischief.

I discriminate all the time against people who don't have good credit or who are criminals, etc."  

Some states limit you on how much you can charge the tenant, some let you charge whatever you want.I never used Smartmove, so I don't know if they have an option where they will also do criminal/eviction/employment/landlord, etc. on top of credit.We used these guys:http://www.cbacredit.com/Index.aspxWe didn't pay for their full service option, as I did some of the tenant screening myself, but they do offer full screening, including employment, landlord references, etc.In CA, for example, you can only charge around $42 for the application fee, even if it costs you more than that.
