Seller Financing Questions

[Nick Causa]

A friend of mine wants to sell his house. Its a great opportunity for my wife and I for a rental and I’d love to pursue it but we dont have enough for the down payment. He still has a mortgage on it so is seller financing still an option? I feel like I’ve heard the owner needs to own it outright for that to work because of the due on sale clause? Is that always correct? If not how can we make it work? Any other suggestions other than seller financing how we can make this work? Go in on it with somebody? I’m thinking along the lines not of “we can’t afford it” but “how CAN we afford it”.
