How to structure a three property deal?

[Jared Sveen]

Hey everyone, 

I found a seller who has three duplexes that are not on the market yet but he is looking to sell off all of the properties because he is sick of doing the landlord thing.  I am very interested in buying the places but still need to find out what he's looking for on each of them as he isn't sure his partner will let him sell them (as they currently cash flow).  I was curious as to if anybody has any creative ways of approaching or structuring a deal to buy all the properties (either all at once or one every few months) assuming he can actually sell them. 

Thanks in advance!
