How to screen tenants when the tenant is just moving to a new state

[Joey Fontenot III]

I've gotta potential tenant whom I am meeting with tommorrow to go through the screening process my plan is to check their background, criminal, and eviction history. In addition I am planning on checking on their proof of monthly income. The issue I am facing is they are just moving down to the area from up in Michigan and have not spent any time down in Alabama. Therefore what would be the best way using an online screening service to go through the process.. Possibly using a 50 state check or simply using the state of Michigan online for their history?

I am also curious if anybody else out there has had a potential tenant call them telling them they have the full month's rent and deposit and are ready to move in ASAP..Is this a good or bad thing?
Thanks
