Seller financing for motivated sellers: how an owner financing offer works, with the payment math
Updated · by the LowBaller team
Seller financing, also called owner financing, is when the seller lends you part of the purchase price instead of a bank. You pay a down payment at closing, then make monthly payments to the seller, usually with a balloon payment of the remaining balance after a few years.
For investors, it is the other half of the lowball conversation. Some owners will never accept 30 percent off for cash, but will accept close to full price paid over time, because what they want is income, not a lump sum. You trade price for terms. This guide shows when that trade works, the documents involved, the payment math on a real example, and the legal traps to clear first.
Definition
Seller financing: A sale in which the seller acts as the lender: the buyer pays part of the price at closing and the rest in installments to the seller, under a promissory note secured by a mortgage or deed of trust on the property.
How does seller financing work?
You and the seller agree on a price, a down payment, an interest rate, a payment schedule and a balloon date. At closing, title transfers to you as usual. Instead of a bank wiring the balance, you sign a promissory note (your promise to pay) and a mortgage or deed of trust (the seller's security, which lets them foreclose if you stop paying). Both are recorded with the county.
- Purchase agreement: the price and the financing terms, with the seller financing spelled out.
- Promissory note: amount, rate, payment, due dates, late fees, balloon date and prepayment terms.
- Mortgage or deed of trust: recorded against the property so the seller has a secured claim.
- Closing through a title company or attorney: title search, title insurance and proper recording, exactly like a bank-financed sale.
- Loan servicing (optional): a third-party servicer collects payments, tracks the balance and issues year-end statements, which keeps the relationship clean.
When does a motivated seller prefer terms to a cash lowball?
Seller financing fits owners whose problem is not a lack of cash today. It rarely fits owners whose problem is a payoff or a deadline. Match the offer to the problem.
| Seller situation | Cash lowball | Seller financing | Usually better for the seller |
|---|---|---|---|
| Tired landlord, owns free and clear | Lump sum, but a steep discount | Near-full price, monthly income, no tenants | Seller financing |
| Older owner who wants steady income | Cash to reinvest | Interest income, and gain may be spread over years (ask a tax advisor) | Often seller financing |
| Heirs who must split the estate | Clean split at closing | Payments to divide for years | Cash |
| Pre-foreclosure owner with a mortgage | Pays off the loan and stops the foreclosure | Usually impossible, the loan must be paid | Cash |
| High equity, behind on property taxes | Pays the taxes, deep discount | Down payment covers the taxes, terms on the rest | A hybrid of both |
| Vacant house that would not sell retail | Fast exit | Higher price, but the owner stays exposed if you default | Depends on the owner's need for cash |
Seller financing terms, with the monthly payment math
Example: a house worth $250,000 that the owner holds free and clear. Your cash offer is $175,000, which is 30 percent under value. Your terms offer is $235,000 with 10 percent down ($23,500). The seller carries the remaining $211,500 at 6 percent, with payments calculated on a 30-year schedule and the balance due as a balloon after five years.
The monthly payment uses the standard amortization formula: payment = P x r / (1 - (1 + r)^-n), where P is the amount financed, r is the monthly rate (6 percent / 12 = 0.5 percent) and n is the number of payments (360). That gives $1,268.05 a month. After 60 payments the balance is about $196,810, which you pay off at the balloon, usually by refinancing or selling.
| Term | Cash lowball offer | Seller-financed offer |
|---|---|---|
| Purchase price | $175,000 | $235,000 |
| Paid at closing | $175,000 | $23,500 (10% down) |
| Amount financed by the seller | None | $211,500 |
| Interest rate and schedule | None | 6%, 30-year amortization |
| Monthly payment to the seller | None | $1,268.05 |
| Balloon after 5 years | None | About $196,810 |
| Seller collects over 5 years | $175,000 at closing | About $296,393 ($23,500 + $76,083 + $196,810) |

The terms you can negotiate
Price is only one lever. Each term below changes what the deal is worth to each side. Offering a higher price with a lower rate, or a longer balloon with a bigger down payment, lets you find a structure that gives the seller what they care about most.
- Down payment: more down gives the seller security and cash today. Less down preserves your cash.
- Interest rate: set by negotiation, within any state usury limit. A lower rate can justify a higher price.
- Amortization: a longer schedule lowers the payment. A shorter one builds equity faster.
- Balloon date: gives the seller a clear end. Make it long enough that you can realistically refinance or sell.
- Prepayment: allow it without a penalty so you can refinance early.
- Taxes and insurance: agree who escrows them and require the seller to be named on the insurance.
- Default terms: late fees, grace periods and the cure period before the seller can foreclose.
The due-on-sale clause and other legal cautions
If the seller still has a mortgage, seller financing gets risky. Most mortgages contain a due-on-sale clause that lets the lender demand the full balance when the property is transferred, and the federal Garn-St Germain Act of 1982 generally makes those clauses enforceable. Structures that leave the old loan in place, such as a wraparound mortgage or buying subject-to, carry that risk. Lenders do not always call the loan, but you should never promise a seller that they will not.
Other rules can apply too. When the buyer will live in the home, federal lending rules and state licensing laws can treat the seller like a lender, with limited exemptions for people who finance only a few sales. Many states cap interest rates, and some have special rules for installment contracts. Rules vary by state, so have a local real estate attorney draft or review the note and security instrument, and close through a title company or attorney.
Never skip the title work
Seller financing does not mean informal. Run a full title search, buy title insurance, and record the deed and the mortgage or deed of trust. An unrecorded deal protects neither side.
Seller financing vs subject-to vs a cash offer
| Structure | What happens to the seller's loan | Who holds title | Main risk |
|---|---|---|---|
| Cash offer | Paid off at closing | You | You need the cash or a lender |
| Seller financing (free and clear) | There is none; the seller becomes the lender | You | Your default; the seller can foreclose |
| Subject-to | Stays in place in the seller's name; you make the payments | You | Due-on-sale clause; the seller's credit is exposed |
| Wraparound mortgage | Stays in place; your payment to the seller covers it | You | Due-on-sale clause; the seller may stop paying the underlying loan |
How to pitch seller financing without pressure
Lead with the seller's goal, not your structure. If an owner says they do not need the money all at once, or that they are worried about taxes on the sale, ask whether a monthly payment would suit them better than a lump sum. Then put two offers side by side in writing: the cash number and the terms number, with the total collected under each. Our lowball offer letter template works for both.
Be honest about the trade-off. The seller collects more in total but waits for it, and they carry the risk that you stop paying. If the owner needs cash now, to stop a foreclosure or split an estate, a fair cash offer is the better answer.
The best seller financing candidates are owners with high equity and long tenure. LowBaller's model scores both: high equity (60 percent or more) and ownership of 15 or more years. When you unlock a seller on LowBaller, it pulls the county record of open loans, so you know before you call whether there is a mortgage to work around.

Frequently asked questions
How does seller financing work for the buyer?
The buyer pays a down payment at closing and signs a promissory note to the seller for the rest, secured by a mortgage or deed of trust on the property. The buyer takes title, makes monthly payments to the seller, and usually pays off the remaining balance at a balloon date by refinancing or selling.
What is a typical interest rate for seller financing?
There is no standard rate; it is negotiated between buyer and seller. Sellers often compare it with bank mortgage rates and what their money could earn elsewhere, and a lower rate can justify a higher price. Many states cap interest rates, so check your state's usury limit with a local real estate attorney.
Why would a seller offer owner financing?
Owner financing can get the seller a higher price, monthly income and interest earnings, and it widens the pool of buyers. It suits owners who hold the property free and clear and do not need a lump sum, such as long-time landlords. Some sellers may also spread taxable gain, which a tax advisor should confirm.
Can you do seller financing if the seller has a mortgage?
Sometimes, but it is risky. Most mortgages have a due-on-sale clause that lets the lender demand the full balance after a transfer, and federal law generally allows lenders to enforce it. Wraparound and subject-to structures leave that risk in place. Have a local real estate attorney review any structure before you offer it.
Is seller financing safe for the seller?
It can be, if it is documented properly. The seller should get a meaningful down payment, a recorded mortgage or deed of trust, proof of insurance naming them, and ideally a third-party loan servicer. If the buyer stops paying, the seller can foreclose, which takes time and money, so they should vet the buyer carefully.
