screen tenant, (ask for copy of security despoit check)

[Account Closed]

Hey,
I have a tenant who seems honest but i asked her for a copy of the security deposit check that she will get back from her previous landlord. She told me she gave cash and she is getting back cash, and didn't want to give out her bank account statement. Is that wrong to ask for that ( i want to know she took care of the property) or how do you guys go about this besides a landlord reference.
