So here is exactly what works for us 100% of the time: I/we,the undersigned, authorize (Landlords name) and its agents to obtain an investigative consumer credit report including but not limited to credit history, OFAC search, landlord/tenant court record search, criminal record search and registered sex offender search.

Also be sure to closely examine your projected CAM charges.

If you do not take convicts, then this is a simple answer...NO.Once you start looking at the crime, and making judgments, you leave yourself open to that one person you say "no" to that turns around and sues you for discrimination because they happen to be a protected class, and you have a history of selective enforcement that they will argue was pointed at them because of their protected class.Next you'll have a sex offender who claims he was just peeing in public near a school....and the list goes on. 

Thinking it makes more sense to use a cheap solution that just handles payments, and I can handle the CAM reconciliation at the end of the year.

It's not the lender's cash that is in the house...your's cam out when you refinanced it, and....When you re-use that same cash again, and repeat the refinancing, you are leveraging your cash multiple times.

However if you live in the home, there are allowances for additional legal discrimination because you may not wish to live with a member of the opposite sex. 

I used what @Rick Baggenstoss mentioned, a deer cam.  

The tenants pay above base rent with CAM to reimburse.

And that's like learning about sex from the other 12 year olds in the class.

Any recommendations on age, sex, likes & interests, etc.?
