When a buyer can't qualify for conventional financing or wants faster closing, the seller sometimes steps in as the lender. This arrangement—often called an owner-carryback mortgage or seller financing—can open doors for non-traditional borrowers, but it comes with legal and financial complexity both parties need to understand.
How the structure works
The seller conveys title to the buyer at closing and the buyer signs a promissory note and deed of trust (or mortgage, depending on the state) directly to the seller. The note spells out the interest rate, payment schedule, and maturity date. Payments flow to the seller each month just as they would to an institutional lender. These figures are illustrative; rates and products are subject to change and this is not a commitment to lend.
Many seller-financed notes are structured as short-term balloons—perhaps five to seven years—with the expectation that the buyer will refinance into conventional financing before the balloon comes due. The seller remains the lienholder and can foreclose if the buyer defaults, following the same legal process any lender would use.
The due-on-sale problem
Most residential mortgages include a due-on-sale clause that lets the lender accelerate the full balance if title transfers. If the seller still owes money on their own mortgage, creating a carryback note without paying off that loan can trigger the clause. The seller's lender can demand immediate payment in full, and if the seller can't pay, that lender forecloses—wiping out the buyer's interest. Buyers relying on seller financing need to confirm the property is free and clear or that the existing lender has agreed in writing to subordinate or permit the arrangement.
Documentation and title work
Even though no institutional lender is involved, the transaction still requires a settlement agent, title insurance, and recorded documents. The promissory note, deed of trust, and any subordination agreements must be drafted carefully—ideally by a real-estate attorney. Title insurance protects the buyer against unexpected liens, and many title companies will insist on an attorney opinion letter before insuring a seller-financed deal. Recording the deed of trust in the county land records gives the seller a perfected lien and puts future creditors on notice.

When it makes sense
Seller financing can work for buyers with credit blemishes, irregular income, or properties that don't meet agency guidelines—think fixer-uppers or non-warrantable condos. Sellers benefit when they want installment-sale tax treatment, need income over time, or are selling in a slow market. The trade-off is risk: sellers must be prepared to foreclose if the buyer stops paying, and buyers pay for the seller's higher perceived risk through above-market rates or larger down payments.
If you're exploring seller financing as a bridge to conventional lending later, start an application once your credit and documentation are ready. Alliance brokers can help you understand what underwriters will expect when that balloon comes due.
