Just for reference for anyone reading this, I spoke with an attorney and this is what we came up with; I have a notarized copy of the quit claim deed in hand before close of escrow and I will be submitting it after close of escrow (this meets the non assignable stipulation) I also have a contract stating our intentions with the wholesaler (between us). 

Not if you expect it to be accepted by a court.The whole idea of a notarized signature is to be a disinterested witness attesting to the validity of the signatures on a document.If that notary has a vested interest in the documents, a court will view it as being tainted and not above question.I wouldn't even recommend an employee of a company notarizing the signatures if the company the employee works for has any vested interest in the transaction.Truly independent notaries are easy to find.

The county recorders require a notarized disclosure from the the owner upon assignment that states that excess proceeds are available, how much much they are, and that they understand that they do not need to go through any intermediary and that there is no charge for applying for the proceeds.  

He wants to give guarantee with a notarized memo.

You better get a notarized document from the seller stating that they understand the loan is staying in their name, that they will be responsible if you don't make the payments, and that you are not legally obligated to do so.If you get into a situation where you cannot make the payments, you should immediately contact the seller and make arrangements to deed the property back to them.

I had to sign a notarized affidavit that I had never done a loan in Nevada which I had not.

Maybe try to find the previous owner and get a notarized statement from him for a few hundred dollars, that he doesn't know those people and never leased to them

And from what you and Wayne are saying, a notarized Deed of Trust is looking like my best option at this point.  

If you are buying a previously owned home, it is recommended that you obtain a notarized bill of sale as proof of ownership.

Similarly, we require that all disbursement instructions require a notarization and any changes are verified in writing (email) and orally (phone or in person) with the recipient/client.
