seller financing

I am seeking a knowledgeable person who can add to or write a better seller financing pitch. The Seller is interested in the idea of it but would like a formal document to review. my first draft is as follows: Dear Sir I hope all is well with you and your family. In the follow you will find my proposal regarding your 16 unit property in Josiah’s Bay and the methodology that will be used to fully finance the purchase as verbally discussed on the __ of __ 2019. For the sake of clarity, my offer is as follows. It is my intention to purchase your 16 unit property outright, using the seller financing technique. (Owner financing is when a property owner finances the purchase entirely or in part, with the person or entity seeking to buy a property.) I am asking in good faith, that you allow me to manage the property for a period of six months, you then allow the income generated for that 6 months period to be used as a down payment towards a mortgage loan, and this mortgage would then be used as payment to buy your property at no risk to you. However, in the event the loan is not approved, the full balance of rental income would be paid back to you forthwith. The parameters of the lease agreement is as follows: Additionally, please see a few other possibilities with regards to seller financing;  The owner provides full down payment on behalf of buyer to secure full loan amount.  This saves the 6 months waiting time for both the buyer and seller.  Full down payment amount to be included in final purchase amount.  In the event the satisfactory amount is not achieved, the full down payment is to be returned to seller.  The owner allows the buyer to collect rental income for 6 months. Rental income is used to finance down payment for full loan amount.  8 months property management agreement to allow for full purchase amount through bank financing.  Full down payment amount is to be included in final purchase amount.  In the event the satisfactory amount is not achieved, the full down payment is to be returned to seller.  The owner acts as the bank and finance the entire sales price to the buyer who pays all payments to the owner for a set amount of time  The property will be fully managed by the buyer.  A pre-determined monthly or bi-yearly payment to seller.  An agreed interest rate and payment. The options above are for us to continue our dialog and come to an agreement of mutual benefit. I await your favorable response.
