Estimate only. The buyer's payment is principal and interest amortized over the full amortization period, and whatever principal is left comes due as a balloon payment at the end of the balloon term. Net cash at closing is the down payment minus your closing costs and assumes your existing mortgage stays in place; if your lender requires a payoff at closing, that balance comes out of it too. Lifetime payout nets your own mortgage payments and payoff over the balloon term, and assumes your balance stays roughly flat until then. The buyer's own taxes, insurance, and HOA are not included, and the seller's carrying cost is their current mortgage payment plus the taxes and insurance you entered. Seller financing has legal, tax, and licensing considerations — we'll walk through the structure with you and your professionals before anyone signs.

Structuring a seller-financed sale?

The numbers are only half the conversation. We'll review the buyer's credit, the seller's existing mortgage, and the terms with you before anyone signs.

FAQ

Seller finance questions.

What is seller financing?+

Seller financing means the seller acts as the lender instead of a bank. The buyer pays a down payment, signs a promissory note, and makes monthly payments to the seller, who earns interest on the balance over the agreed term.

Why would a seller agree to carry the loan?+

Sellers often earn more interest than they would in a savings account, spread the sale across years instead of taking one lump sum, avoid some closing costs, and open their home to buyers who can't qualify for a bank loan. This calculator shows the monthly spread and total interest so the trade-off is concrete.

What happens to the seller's existing mortgage?+

Most mortgages include a due-on-sale clause that lets the lender call the loan due when the home transfers. That's why the calculator compares the seller's current payment against the income the new note produces before you structure anything.

What rate and term are typical?+

Seller-financed notes often price above bank rates to reflect the risk, commonly in the 5–10% range with 5–15 year terms, sometimes with a balloon payment. Rules vary by state, and financing repeatedly can raise licensing questions, so review the structure with your attorney or CPA before signing.

What is a balloon payment?+

A balloon payment is the remaining note balance that comes due in full at the end of the balloon term — commonly 3 to 7 years. The buyer's monthly payment is calculated over the full amortization period, so the balloon is whatever principal is left when the term ends. Buyers usually plan to refinance or sell before it comes due, so build that timeline into the conversation.
