land- seller wants cash, buyer wants terms, note buyer ready

[Przemyslaw Krol]

This is about land in California. The Seller is asking $100k cash one payment. We found a buyer willing to do payments for 10 years. we found a note buyer who will buy the note unseasoned for $150k. Is there a contract that would allow us to control this process to pay off the seller within 1 year. Some sort of double close . Seller will not carry the not but can enter into an option.

Please Help!
