Few deal terms generate more uneasy phone calls than the seller note. You spend decades building an Orange County manufacturer or a San Diego services firm, a credible buyer arrives with a strong offer — and then the term sheet asks you to lend part of your own purchase price back to the company you just sold. This article is the seller note explained from the seller’s side of the table: what the instrument actually is, where the real risks hide, how the interest and repayment math works, and the structural protections that separate notes that get paid from notes that get litigated.
For owners of established Southern California businesses in the $3M–$25M sale range, seller financing is a normal feature of the landscape, not a red flag in itself. The question is never simply whether to accept a seller note — it is how large, how protected, and on what terms.
What a Seller Note Is and Why Buyers Ask for One
The financing gap in lower-middle-market deals
A seller note is a loan from you to the buyer, documented by a promissory note, with part of the purchase price paid over time with interest instead of wired at closing. Buyers use them to bridge the gap between the total price and what senior lenders will advance. The structural reality in Southern California makes this common: SBA 7(a) loans cap out at $5 million, while a healthy business with $1M–$5M of EBITDA in Los Angeles, Orange County, San Diego, or the Inland Empire routinely prices well above that. Conventional bank debt covers part of the difference; equity and seller financing typically cover the rest.
What a note signals — and what it shouldn’t
A modest seller note can be a constructive signal: you are confident enough in the business to keep some skin in the game, and buyers and their lenders read it that way. What a seller note should never be is a substitute for buyer capital. If the structure leans heavily on your paper because the buyer brings little of their own money, you have not sold your business — you have handed over the keys and kept most of the risk. Vetting the buyer’s equity and funding sources matters as much as the note’s terms.
The Seller Note’s Real Risks: Subordination and Standby
You get paid after the bank
The most consequential word in seller-note risk is subordination. Senior lenders will require your note to sit behind their debt, documented in a subordination or intercreditor agreement. If the business stumbles, the bank is paid first, and your note may be blocked from receiving payments at all while a senior default is outstanding. Read the subordination terms as carefully as the note itself: the difference between “payments continue unless the senior loan is in default” and “payments require the lender’s ongoing consent” is the difference between a predictable income stream and a hostage negotiation.
Standby provisions and payment blackouts
Where SBA financing is involved, expect stricter treatment: when a seller note is counted toward the buyer’s required equity injection, SBA rules generally require it to sit on full standby — no payments of principal or interest at all — typically for the first two years of the loan, and lenders sometimes negotiate longer. None of this makes a note unacceptable; it makes the real question “what do I actually receive, and when, in the downside case?” Model your note assuming the senior lender exercises every right it has, and size the cash-at-closing portion of your deal so that your retirement does not depend on the note performing perfectly.
Interest, Terms, and the Worked Math
How seller notes are priced
Because a seller note is junior, unsecured or second-lien, and illiquid, it should carry a meaningfully higher rate than the senior bank debt in the same deal — you are being paid for risk and patience. There is also a tax floor: charge at least the IRS Applicable Federal Rate for the note’s term, or the IRS can impute interest you never received. Typical structures pair a multi-year term with either steady amortization or interest-only payments and a balloon; each shifts risk differently, and the right answer depends on how the business generates cash. This is general information rather than tax or legal advice — have your CPA review the rate and your attorney the note before you sign.
A worked example: what a $2 million note actually pays
Take a $10 million sale of an Inland Empire distribution business in which $8 million is paid at closing and $2 million is carried as a seller note — interest-only at a hypothetical 8% for five years, with the principal due as a balloon at maturity:
| Line item | Amount |
|---|---|
| Seller note principal | $2,000,000 |
| Annual interest (8%, interest-only) | $160,000 |
| Total interest over the five-year term ($160,000 × 5) | $800,000 |
| Balloon principal repayment at maturity | $2,000,000 |
| Total received over the life of the note | $2,800,000 |
On paper the note adds $800,000 of interest to your proceeds. The honest read is different: that $2,800,000 arrives only if the business performs and the senior lender never blocks payments. The seller note is the slice of your price that stays exposed to the company’s future — which is exactly why its size and protections deserve more negotiation than its rate.

Structural Best Practices Before You Sign
Security, guarantees, and covenants
Negotiate for whatever credit support the senior lender will permit: a second-priority security interest in the business assets, a personal guarantee from the buyer’s principals where the buyer is an individual or small group, and a guarantee from the parent entity when you are selling to a platform. Add information rights — quarterly financial statements at minimum — so you are not discovering problems eighteen months late, and an acceleration clause making the note due in full if the buyer resells the company. None of these terms is exotic; they are simply easy to forget when the headline number looks good.
Vet the borrower like the lender you are becoming
The moment you accept a note, you are a creditor, and the credit is the buyer. A funded acquirer backed by an established private equity firm, with verifiable committed capital and bank relationships, is a different credit than an individual searcher stretching for a deal twice their resources. This is one place a direct sale genuinely helps: negotiating with a single funded decision-maker means you can ask hard questions about capitalization and get direct answers, rather than relaying them through a broker with a commission riding on the close — a commission that, as our Broker Fee Savings Estimator shows, comes off the top whether or not your note ever gets paid.
Size the seller note around your downside, not your upside
The right seller note is one you could afford to lose without changing your retirement, and the right total structure is one where the seller note is the seasoning, not the meal. That is a blunt standard, but it produces good decisions: it pushes the negotiation toward more cash at closing, keeps the note a minority slice of total consideration, and forces the structural protections above to be real rather than decorative. Every deal we structure starts from the seller’s priorities — for most Southern California owners, that means certainty first and yield second.
Get the Whole Structure Right, Not Just the Note
A seller note only makes sense in the context of the full deal — price, cash at closing, and the protections around everything deferred.
