A mortgage is not a law of nature. It is one company’s solution to one problem: the seller wants all their money now, and the buyer does not have it. A bank steps in, pays the seller, and collects from the buyer over 30 years.
Useful. Also optional. If the seller does not need all the money today, the bank has nothing to solve — and they can simply collect payments themselves.
That is seller financing, also called owner financing or a seller carryback.
How it works
The mechanics are straightforward:
- Title transfers to you at closing. You own the property.
- You sign a promissory note — a written promise to pay the seller a stated amount, at a stated rate, on a stated schedule.
- The note is secured by a mortgage or deed of trust recorded against the property. If you stop paying, the seller can foreclose, the same way a bank could.
- You pay the seller directly, usually monthly, often through a third-party servicing company that handles records and tax reporting.
No underwriter. No score threshold. The seller decides whether to trust you, using whatever evidence they find convincing.
How it differs from Subject To
These get confused constantly, and the difference is simple once you see it. It is about whether a bank loan already exists.
- Subject To — an existing bank mortgage stays in place, in the seller’s name, and you take over those payments. Requires that a loan exists.
- Seller financing — a brand-new agreement is created between you and the seller. Works best when the seller owns the property free and clear, with no loan to work around.
Rough rule: a seller with a mortgage and little equity points toward subject-to. A seller who owns outright — often someone older who paid the house off decades ago — points toward seller financing. Deals sometimes combine both.
A paid-off house sold conventionally hands the seller a large taxable lump sum they then have to figure out what to do with. Carrying the note instead can spread the tax impact, produce monthly income at a rate better than a savings account, and keep the property as security if the buyer defaults. For the right seller it is genuinely the better deal — which is why this is a conversation, not a favor you are asking for.
The terms that actually matter
Everything is negotiable here, which is the whole advantage and also where people get hurt. Six terms carry most of the weight:
Purchase price
Price and terms trade against each other. A seller who cares most about the headline number may accept a lower rate or smaller down payment. Do not negotiate price in isolation.
Down payment
Typically 5–20%, entirely by agreement. It is the seller’s protection — it makes walking away expensive for you.
Interest rate
Negotiated, and frequently compares well to bank rates for both sides. Be aware that federal and state rules can apply to seller-financed notes, particularly on owner-occupied residential property. This is a question for an attorney in your state, not for an article.
Amortization and term
Payments are often calculated on a 30-year schedule to keep them affordable, while the actual term is much shorter. Which leads to the term people miss:
The balloon
Most seller-financed notes include a balloon payment — the full remaining balance due at a set date, commonly three to five years out. Sellers use it because few want to wait 30 years for their money.
This is the single most important number in the note. If you cannot refinance or sell before that date, you can lose the property. Never sign a balloon you have no plan to satisfy.
Default and cure terms
What happens if a payment is late? How many days to cure before default? These should be written plainly and understood by both sides before signing, not discovered during a hard month.

Seller financing done properly is not less formal than a bank deal. It is differently formal:
- Title insurance and escrow. Non-negotiable. You need to know exactly what liens exist before you take title.
- A recorded security instrument. The mortgage or deed of trust is what makes the seller’s position real.
- A real attorney drafting the note. In your state. Not a template from the internet.
- A third-party servicer. Handles payments, amortization records, and year-end tax documents. Removes an entire category of future dispute for a small monthly fee.
- Insurance naming the seller’s interest. Their security is the building. If it burns and no one told the insurer, everyone loses.
Where to find these sellers
You are looking for owners with no mortgage and a reason to prefer income over a lump sum. In practice: long-time owners, inherited properties, tired landlords, and listings that have sat unsold for months.
The approach that works is not a pitch. It is a question — something close to “Would you be opposed to receiving monthly income on this instead of a lump sum?” Most sellers have never been asked, and many have never known it was possible. You are not talking them into a concession; you are surfacing an option they did not know existed.
Some will say no. That is fine. You only need the ones for whom it is genuinely the better arrangement.
