How to screen a tenant who never had a landlord before?

[Dennis Meppelink]

Hi there, 

Every body knows you have to screen your new tenant.

One of the points is to check the previous landlords of the tenant.

What can you do if the tenant sold his house and wants to rent your house? Can you do any check?

What if it is a young tenant who left his eldery home? Can you call his mother??

What if the tenant is deforced and is gonna leave the house (his or her own house). How can you check the living standards of the tenant in this case?

Best Regards,

Dennis
