We make a lot of seller financing offers and it IS a great way to get closer to a sellers asking price, particularly when their sales price may not be realistic. I interpret your summary that your end goal is to sell it with seller financing and not payoff the note to your seller for the 5years?
I like how you are thinking - refocusing the seller on the total payments over the period of the loan rather than just the sales price.
Does the seller need the cash to buy the next home? If so, Seller Financing may be a tough sell. Also, the gap between the sellers mental sales price and your sales price may be too big.
If he is open to seller financing, we like to make 3 offers and "steer" the seller towards seller financing with small downpayments. Assuming your 5yr balloon structure with 5% interest, Maybe something like:
- $230K - Cash Price. (Cash + Conventional Mortgage)
Total Paid: $230,000
- $240K - Seller Financing ($230K financed, $10K down payment)
Total Paid: $295,287 (Downpayment, all P&I payments, balloon payment)
- $260K - Seller Financing ($260K financed, $0K down payment)
Total Paid $322,499 ((Downpayment, all P&I payments, balloon payment)
If you can get him all the way down to your example of a $200K sales price ($260K total paid) all the better but it feels like a bit of a stretch.
I don't have all the info so this may not track completely to your example but your basic idea of refocusing the seller on the sum of total payments, vs. the sale price, is a great strategy...
