What Is Seller Carryback?
In a seller carryback, the buyer gets the deed at closing, but the seller holds a note for part of the price — say $100,000 of a $350,000 sale. The buyer makes payments to the seller (principal + interest) over 5–10 years, often with a balloon payment at the end. The seller benefits: installment sale treatment spreads capital gains tax over the payment period instead of a lump sum at closing. The buyer benefits: easier qualification, flexible terms, and sometimes a lower down payment. Sellers often agree when they're retired, inherited the property, or the market has few qualified buyers. Watch for due-on-sale clauses in existing mortgages — the lender could call the loan if they discover the seller financing.
A seller carryback is when the seller of a property acts as the lender — instead of the buyer getting a bank loan for the full amount, the seller "carries back" a portion of the purchase price as a loan, secured by a deed of trust and documented in a promissory note.
At a Glance
- What it is: Seller finances part of the purchase price; buyer gets deed, seller holds note
- Why it matters: Installment sale treatment defers seller's capital gains; buyer gets creative financing without a bank
- Typical terms: 5–10 year term, 6–8% interest, balloon at end
- Risk: Due-on-sale clause in seller's existing mortgage can be triggered
How It Works
Structure. At closing, the buyer pays the down payment (and any first mortgage) to the seller. The seller deeds the property to the buyer. The buyer signs a promissory note for the carryback amount and grants a deed of trust (or mortgage) to the seller as security. The seller is now a lender — they receive monthly payments of principal and interest. If the buyer defaults, the seller can foreclose.
Installment sale treatment. The seller doesn't recognize the full gain at closing. They report gain proportionally as they receive principal payments. If they'd have $80,000 in gain on a $100,000 note, they might recognize $8,000 per year over 10 years instead of $80,000 in year one. That spreads the tax hit and can keep the seller in a lower bracket. The buyer's interest payments are deductible (for investment property) as mortgage interest.
Typical terms. Carryback notes often run 5–10 years with a balloon payment — the buyer pays interest (and sometimes a bit of principal) monthly, then pays off the balance at the end. Interest rates typically run 6–8%, between bank rates and hard money. The seller may accept interest-only for a period to keep payments low.
When sellers agree. Retirees who want steady income. Heirs who inherited a paid-off property and don't need a lump sum. Sellers in slow markets where buyers can't get financing. Sellers who want to defer taxes. The key is finding a seller with motivation — not everyone will carry.
Due-on-sale risk. If the seller has an existing mortgage with a due-on-sale clause, transferring title to the buyer could trigger the lender to call the loan. Some sellers do a "wrap" or "all-inclusive" deed of trust where the existing loan stays in place and the buyer pays the seller, who pays the bank — but that's more complex and has its own risks. Consult an attorney.
Real-World Example
Investor in Birmingham, Alabama. You find a seller who inherited a paid-off duplex. They want $350,000 but don't need all cash — they'd rather have $250,000 now and $100,000 over time with interest. You agree: $250,000 down, $100,000 seller carryback at 7% for 7 years with a balloon.
You get the deed. You sign a note: $100,000, 7% interest, interest-only for 5 years, then balloon. Your payment: $583/month ($100,000 × 7% ÷ 12). In year 6 you refinance or sell and pay off the $100,000. The seller receives $583/month for 5 years, then $100,000. They've spread their gain over the payment period and earned 7% on the carryback. You've acquired a property with $250K down instead of needing $350K or a bank loan for the full amount.
Pros & Cons
- Seller defers capital gains via installment sale treatment
- Buyer gets flexible terms, easier qualification, sometimes lower down payment
- Seller earns interest (6–8%) on the carryback — often better than a CD
- Can close deals when bank financing is tight or slow
- Seller takes default risk — if buyer doesn't pay, foreclosure is the remedy
- Due-on-sale clause in seller's mortgage can complicate or kill the structure
- Seller has illiquid capital tied up until the note is paid
Watch Out
- Due-on-sale risk: If the seller has a mortgage, transferring title may trigger the lender to call the loan — get legal advice before structuring
- Default risk (seller): Vet the buyer; secure the note with a recorded deed of trust; have a foreclosure plan
- Tax risk (seller): Installment sale rules have exceptions (e.g., depreciation recapture may be accelerated); consult a CPA
- Balloon risk (buyer): Plan for the balloon — refinance or sale — don't assume you'll extend

The Takeaway
A seller carryback is creative financing that benefits both sides: the seller spreads gains and earns interest, the buyer gets flexible terms. It works best when the seller is motivated — retired, inherited, or in a slow market. Structure it properly: promissory note, deed of trust, and clear terms. Watch for due-on-sale clauses and get an attorney involved.
