Best Answer - Chosen by Asker:

Go to your state that you live in on their site and go from there.
You may look there for free with your state especially for a residential thing like that. The local police in your area will be able to tell you by their social security number and drivers license.
You must get those before renting to them and they should always provide a reference anyway. Like the last place of residence.
