As Tim said, find a super reliable screening solution and be sure to run credit, criminal, and eviction.  

I would only utilize that service for tracking criminal history checks and credit checks to vet those aspects of the tenant.

Do they have a criminal history or other black marks like bad credit?

@Harry Karambizi, Not PAYING taxes is a civil case, not FILING a personal tax return is a criminal felony. 

I am telling them all the standard requirements before even seeing the unit, 3x rent, good credit, no criminal record and no evictions.Thanks 

@Theresa Harris They're criminally high. 

Furthermore, this is a civil issue, not criminal, so the police are NOT the correct party to seek advice.

If you start installing wood-look tile (criminal in the historic districts) and painting everything gray, you will not come close to the value of the good remodel comps in the more desirable neighborhoods.Good luck!

After the "I'll evict you on Xmas because I’m such a harda**” post, the two 100+ reply threads on “college is good, college is for the sheeple”, and the “should I rent to a felon” thread that morphed into a debate about nature of the criminal justice system in the US, it seems that we have strayed from our roots as a REAL ESTATE forum where people talk and learn about REAL ESTATE related issues to a venue for real estate investors to espouse their world views on any number of given topics that are at best tangentially related to real estate.

I've had lengthy discussions with the compliance officer at the DIvision and it is touchy...and despite what is in statute the Division has autonomy outside of statute...we have revised code, and administrative code, and internal rules, and egotistical politicians that need to punish people for no reason...so, if you're doing anything related to real estate with or without a license in this state, you're open to the Divisions authority.I had a former business partner pay Vena Jones Cox $13,000 for her guru wholesale program in Cincinnati and I about pulled my hair out....so, I guess the point is that despite the rhetoric, criminals are still actively teaching classes on how to break the law...it's like paying for a class that teaches you how to speed....it's insanity.
