I do need to contact the homeowner for permission.

While you can't run a credit report without the tenants' permission, the current lease agreement should provide some good info. 

We have several people market our homes as they are in demand, but I do feel that permission is necessary.

A bank "giving permission to list" is an odd statement.  

I rented out rooms in a house that I rented, with the owners permission, to medical students doing externships in Seattle back in the 1980s.

They can't afford it.Make sure you spell out building rules, where people can smoke cigarettes, drink beer, when are quiet hours, how many people can they have on property before they notify you, how long can a visitor stay before they request permission(I do three nights).  

Contracts are permissible in the subject property state, also I'd structure deal as such so that any default results in forfeiture of property and any payments made are considered merely as rent payments.So, let me know your thoughts BP.

For all I know, they may have tried to seek permission from me through my PM, only to have their request fall on deaf ears.2) I'd like to hear whether their needs are being taken care of by the PN.

permission to speak please.

I'd really like permission to inbox you and go over some strategies in depth to make sure I'm starting out on the right foot as I dont plan to be a life long wholesaler.
