Seller financing stratergies

[Duane Johnson]

Hello Biggerpockets community I need your help

After Repair Value-                                     389,000

Seller is Asking Price-                                        319,000

(I'm going to try to negotiate 272,000)

Rehab Budget- (controlled budget)                     50,000

My Maximum Allowable Offer                            241,750

My question is what would be the best way to structure this deal? The seller is offering seller assistance however I am unfamiliar with this type of strategy. Has anyone ever been in a situation like this and how did you handle it. I've negotiated a number of deals. Can I make this one a creative successful win/win situation?
