Owner finance and 1031

[Avi Garg]

I had an owner contact me through my direct mail campaign and they agreed to owner finance but also want to 1031. I would like to flip this house. Is it possible to accomplish both scenarios? 

I was thinking about having the seller sign a contract with a long closing date (1 year out?) with a stipulation of any money spent in the house improvement will be reimbursed in case of the seller voiding the contract before the closing date?

Any other ideas welcome.
