Conventional Loan with Seller Carrying a 2nd?

[Ryan Landis]

I came across a property that is FSBO and the seller is willing to carry. I want to know how I can structure the deal to put the least amount down while also using conventional bank financing (strong credit, steady W2, etc.). If I was going through a bank I would expect to put 20% down. However, I would prefer to not tie up 20% and save capital for improvements, etc.

Can I have the seller carry 15% and the bank carry 80% (with me providing the remaining 5%)? If not what if we changed the loan amounts to 30%, 65%, and 5%?

I am open to suggestions. Thanks in advance for the help.
