Forms required to wholesale a deal

[Chris Piper]

This may seem like a dumb question, but I've been out of wholesaling for a while. When you do a wholesale deal, you need a purchase agreement with the appropriate clauses to protect yourself and you need to include the fact that you may assign this contract to another buyer so that the seller understands this upfront correct? And secondly, you need to have an assignment agreement you use as a contract between yourself and the cash buyer so you are covered and get paid. Am I correct on both of these items? Thanks in advance.

P.S. If anyone has these contracts they could send me, I would really appreciate it.
