Seller Financing Calculator

When the seller carries the note on a business or property, the deal has two sides most calculators skip. This shows the buyer's real cost, the balloon that comes due, and the seller's actual return, including what the note is worth if the seller ever wants to sell it for cash.

Estimates a fixed-rate amortizing note with an optional balloon. Does not model late fees, prepayment penalties, taxes, or default. Not financial or legal advice. Have a real note reviewed by an attorney.

How an owner-carry note actually works

In seller financing, the seller becomes the bank. The buyer puts money down, and the seller carries a note for the rest at an agreed rate. The monthly payment is usually amortized over a long schedule, like 25 or 30 years, to keep it affordable. But the note often comes due much sooner through a balloon, where the entire remaining balance is owed in a lump sum at year 5 or 7. That is the number that surprises buyers.

A 30-year amortization with a 5-year balloon means the buyer makes 30-year-sized payments, then has to refinance or sell to pay off the big balance still owed at year 5. The longer the amortization and the shorter the balloon, the larger that lump sum. Run different balloon years above and watch the balance due change.

The seller's side: holding the note turns a sale into an income stream plus interest. If the seller later wants cash, they can sell the note to a note buyer, but those buyers pay less than face value to earn a higher yield. That discount is what the resale figure above shows. Pair this with the cap rate and mortgage-versus-invest tools to compare owner-carry against a conventional deal.
