Seller/Owner Financing Questions

[Joe Knurek]

Hoping someone knowledgeable on seller financing can help clarify, I'm mainly interested in utilizing seller financing to negotiate low down payments, my questions are:

Is it typical to get a 30 year fully amortizing loan with seller financing, it seems mostly it's used as short-term financing with a balloon payment? 

Do you typically use a loan servicing company to manage payments? If so do you have any recommendations?

Thanks guys!
