Seller Financing Deal

[Marc Cesar]

Greetings all, I came across a deal that caught my attention because the seller is willing to seller finance for the buyer so long they put down a deposit. Details are as follow, duplex with 6 beds 2 baths, 2592sqft, seller listed property as needing only cosmetic repairs but based on the pictures I assessed that both units would need updated kitchens and baths, a fresh coat of paint, new windows. Property is currently vacant but can rent for 800-950/month. The house has been assessed at 74.5k but the seller is selling for 54.9k. I wanted to gain insight as to how to approach this deal with the seller financing option with little to no money of my owned invested in this deal or structuring it with my own funds being used for the down payment and set it up as to where I could cash the seller out after a certain time frame. Also, is there any way to have the seller pay for the repairs needed? Thanks in advance for any insight.
