Is 20 percent down a rule for seller financing or just an agent's preference?
Say a seller owns a rental free and clear and would rather have a monthly check than a pile of cash to redeploy. A buyer's agent tells the seller to ask for 20 percent down minimum. Where does that number come from? Twenty percent is not a bank rule that applies to a seller carrying paper. It is a common convention, not a requirement. A buyer offering 10 percent and proposing a higher rate to compensate is a reasonable structure, not a red flag by itself, provided the note terms and the property's equity cushion support it. On the recourse point, it is true that in most owner financing structures the seller can take the property back if the buyer stops paying, through foreclosure or, in some structures, a faster forfeiture process depending on the state and how the transaction is documented. That does make the down payment somewhat less about pure loss protection and more about buyer commitment and equity cushion. A larger down payment still matters because it lowers the loan to value, reduces the odds of default in the first place, and covers the seller's costs if the property does need to be taken back and resold.
