Tenant Screening Process?

[Mark Aiken]

Hello, I'm curious what resources investors use to screen potential tenants (e.g. background checks or credit checks) during the application process, other than just Googling the person?  I'm just starting out as an investor and I've acquired 4 units.  The units are currently occupied, but I'd like to be prepared when the time comes.  The properties are in Indiana if that makes a difference.
