Tenant background checks & vetting process

[Jon Kelly]

Hello, 

Could somebody refer me to a strong background check resource or vetting process? I own one rental property, which I've had for 6 months. At this point my background checks and vetting process consists of searching the internet for any information I can find related to the person's name, phone number and email. As I begin to invest into more rental properties, I believe I need a more effective background check and vetting process. Are there certain websites that I should look into, or any other resources? Any help is appreciated, thanks!
