Seller Financing at 30%? How to finance the other 70%?

[Jeff Cody]

Hey BP! I've got a great opportunity in Florida to buy multiple properties from an older investor looking to get rid of 5 SFR's. He's open to financing and we agreed he would carry 30% and I'd finance the other 70% through a bank or other lender.

I'm starting to get advice from lenders now though, that I'll still need to come up with my 20%.  I see my 'skin in the game' as the money I'm putting into the rehabs, but I don't think that will do...  (5 homes will total $1.8M, so my 20% would be $360k, and while doable I'd rather keep that capital for rehab, reserves, and other properties vs down payment)

How have some of you financed the other 70% in a deal like this?   

Thanks!  - Jeff
