What paperwork should I bring along with a Purchase and Sale Agr.

[Brian Shand]

My notes from some of the books I've read tell me to bring a Purchase and Sale Agreement (obviously), a backup PnS Agreement, some creative financing PnS Agreements (owner finance/sub2), Authorization to Release Info from Mortgage Company, Authorization to Release Info from Bank, Property Disclosure Forms, Affidavit of PnS, and a Credibility Packet to leave behind for an unsure seller. 

Are there any other documents or forms that come to mind?
