I conduct credit check and criminal check which includes previous evictions. 

I have seen deals die a day before they were supposed to close because the wholesaler was not entirely truthful to the escrow officer.Quite literally, the escrow officer is sort of like your criminal defense attorney.  

I am going to run his credit and criminal background but here's my general question:If I do rent-to-own with 2k down, I could apply the difference between 900 and 650 toward his mortgage.  

You might look at all convictions case by case and ask questions to determine their eligibility (each state may or may not have laws regarding criminal discrimination).Pets: NO DOGS (unless they are service dogs) PERIOD!

You must apply the same criteria to ALL tenants, to avoid discrimination.After you review the application, (submitted when the person said they would, not 5 days later), have them go to a tenant screening service like NTN or Tenant Reports.com and have them pay for the criminal and background check, the credit check, and eviction history.  

Others probably cannot get licensed do to criminal records.

Should some one "unqualified" (go ahead and argue that if you want, the courts have already ruled) injure themselves in the process, the company could be held both criminally and civilly liable.The "cost of labor" is the cost of living in that locale - it is dictated by no other factors.

But some advice would be to contact that police and ask for their advise because at this point you might be already in the mix for knowing house a criminal (if she is truly guilty).

I search this site: http://www.oscn.net/dockets/Search.aspx to find evictions (in Oklahoma it's called a Forcible Entry and Detainer) and criminal history.  

I'm wondering if I should file criminal charges?
