Seller Financing the downpayment on a 16 unit?

[Stephen Jones]

I have a 16 unit deal in place that cash flows very well, I also know the owner very well also. I have bought up a few properties here of late, therefore my cash flow is pretty thin. Can someone with more experience work up a few seller finance options for me that I can present to this gentleman? 

I was thinking something more along the lines of him carrying the downpayment and charging me interest. I would also come closer to his purchase price if he were to work up a seller finance deal with me. A few details are-

Purchase price- 825,000$

8- 2 BDR 1 BTH

8- 3 BDR 1 BTH

1000 sq ft

Cash flows around 65K yearly

Thanks for the advice! Please fell free to ask anymore questions.
