Seller Financing - How to make it sweet

[Zach Adams]

Been working on this deal for a Triplex and heard from the son of the owner (who is the agent) that they would be open to seller financing the property. I can't qualify for a conventional/FHA right now (not enough cash) and was super excited about my first seller finance deal. But the father decided he needs the cash now and is already involved in another seller finance.

How can I arrange this deal to sweeten it for the father? To get a conventional on this I need 20% down. I don't know if between the seller carry and some additional cash I can get a conventional at 80% LTV and get him paid out at least 80%. Would this work?

This cannot be an owner occupied deal for me right now.  

Any advice is appreciated!
