The LL wins either way.

Explain that your job is to go out and negotiate win/win deals for sellers and investors that you work with.

I figure this would be a win-win for both sides considering the seller would collect a non-refundable deposit, cash-flow for the years I'm leasing it and they wouldn't need to pay a realtor.

If you aren't the winning bidder then the hold comes off.

Being that this will be my first seller financing deal I'm trying to get an idea of properly structure it to where all parties win. 

So it might be a win-win if she stays for a bit while she locates an all one level place and you have time to reno the other side

I think it’s a win win as long as the deal makes sense and you have an exit strategy to be able to sell or continue to project and still make a profit.

Raise your asking price 40k over your initial price as the down payment your looking for, so instead of receiving cash in a lump sum or even 3-5% down payment, you’ll create a win-win situation for everyone involved.

I am interested in educating myself in the process from beginning to end, but I know how valuable time is, so maybe I could develop a system and relationship where we could make this a win-win for both of us.

And the one who sends me the deal I purchase “wins”.
