Yes this is the reason it’s interesting at all. It can also be beneficial for taxes. I never liked it because it seems like a bad deal for the buyer in a way. Say you put down 20k, pay down the loan half way and then something happens and you can’t pay. You can’t sell and recoup your investment.My grandma was quite the business woman and did this often. She had a great attorney that would prepare the paperwork for her. She was always buying and flipping properties. She bought into a motel and ended up selling it to a investment group, owner financed. They put down a down payment and paid monthly over 10 years. At the end of the 10 years, their balloon payment at the end was nearly what the original purchase price was. My grandma always said, “Why let the banks make all the money on the interest?”
