Newbie looking for advice on seller financing

[Mat Thomas]

I am interested in purchasing my first multi-family property.  This would be my first seller-financed deal.  The property that has five units in a recently remodeled home.  I can secure the financing, but would struggle with the down payment funds.   They are asking $350K.  What kind of offer can I propose to entice the seller to seller finance it for me?  My assumption would be to offer full asking price, an interest rate around 5-6%, shorter term with balloon payment after 5 years, and monthly payment around half the rent income ($2K).  Any help is appreciated!
