Seller Financing in a Business Sale: When It Is Worth It

This guide covers why buyers ask for a note, how a note differs from an earn-out, the terms that decide whether the structure is acceptable, and the subordination language that can stop your payments entirely. It is written for owners of lower middle market businesses looking at an offer with deferred consideration.

The other deferred instruments are covered separately: earn-out structures tie money to future performance, and rollover equity converts part of the price into a stake in the buyer's company.

Key takeaways

• A seller note is a debt obligation with a fixed schedule. An earn-out is contingent and can go to zero. The two should be priced differently.
• Across 100 Axial letters of intent containing a seller note, the median note ran from 11.68% of enterprise value in healthcare to 21.00% in technology, with the buyer-type medians spread across a similar band (Axial, 2024, indicative rather than a full study).
• In Q1 2026, cash at close across the Market Pulse segments ranged from 76% to 89% of purchase price (IBBA and M&A Source, Q1 2026).
• Prime stood at 6.75% and SOFR at 3.62% on 14 September 2026 (Federal Reserve H.15; New York Fed). A note priced near prime is junior risk paid at senior pricing.
• Payment blockage in the subordination agreement can suspend your interest while the buyer is in covenant breach with the bank.
• Under the installment method in IRC §453, gain is generally recognized as payments arrive. Depreciation recapture is recognized in the year of sale regardless.

What seller financing in a business sale means

Seller financing is a promissory note issued by the buyer to the seller at closing for part of the purchase price. It carries a stated rate, a repayment schedule, a maturity date, and a place in the capital structure behind the bank.

If the buyer fails to pay, the seller has a creditor's rights, subject to whatever those rights were narrowed to in the subordination agreement.

Why buyers ask for a seller note

Three reasons cover almost every case, and each tells you something different about the buyer.

1. A financing gap. The lender funds a multiple of EBITDA, the buyer contributes equity, and the price exceeds the sum. The note closes the difference.
2. A lender requirement. Banks frequently want the seller to keep money at risk behind them, because a note cannot be repaid ahead of the senior facility.
3. Signalling. A buyer asking for a note is asking the seller to stand behind the numbers in the offering materials, so the negotiation is usually about size and terms.

There is a fourth reason, covered at the end: the buyer cannot fund the price they offered.

Seller note versus earn-out

A seller note is a debt obligation with a fixed schedule that pays regardless of how the business performs. An earn-out depends on hitting defined targets after closing.

The practical difference is the burden of proof. A note pays unless the buyer defaults, and the seller only has to present the schedule. An earn-out pays only if the seller can show the target was met, using accounts the buyer now controls.

Seniority differs too. In a liquidation a note ranks ahead of equity, while an earn-out carries no priority.

The terms that decide whether a seller note is acceptable

Six terms determine whether a note is a reasonable bridge or a discount dressed up as a price. Negotiate them together, because buyers trade generously on the cheap ones.

Principal as a share of the purchase price

Market practice clusters in the low-to-mid teens as a percentage of enterprise value. In Axial's sample of 100 letters of intent carrying seller notes, the sector medians ran from 11.68% in healthcare to 21.00% in technology, and the medians by buyer type sat inside a comparable band.

Treat anything above roughly 25% as a financing problem rather than a structuring preference, and check the cash-at-close figure against the 76% to 89% range reported for Q1 2026.

Interest rate against current benchmarks

The coupon should reflect junior, usually unsecured risk. On 14 September 2026 the US bank prime loan rate was 6.75% and the 5-year Treasury yielded 4.80%, with SOFR at 3.62%.

Seller notes are routinely offered at 5% to 8%, which prices subordinated paper at or below what the senior bank charges. A defensible starting position is the senior rate plus several hundred basis points. Below-market coupons also invite imputed interest treatment, where part of the principal is recharacterized as interest.

Amortization against interest-only with a balloon

Amortizing principal from month one is materially better for the seller than interest-only with a balloon, at the same coupon and term. Each principal dollar repaid early is a dollar no longer exposed to the buyer's credit.

Interest-only structures concentrate the whole principal into one payment years out, when the buyer may need to refinance to make it. Regular amortization also gives an early warning, because a buyer in trouble misses a small payment first.

Term, security and personal guarantees

Three to five years is the common range, and shorter is better. Security is where sellers give away the most value without noticing.

Ask for a second-lien position behind the senior lender, a pledge of the buyer's equity in the acquisition vehicle, and a personal guarantee from the principals where the buyer is an individual, a search fund or an independent sponsor. A note against a newly formed holding company with no assets and no guarantor is an unsecured promise.

Default remedies

Define default precisely: non-payment after a short cure period, breach of financial covenants, a change of control, insolvency events. Then specify the remedies: acceleration of the full balance, a default interest step-up, board observation rights, and in some deals the right to reacquire pledged equity. Each will be tested against the subordination agreement.

Subordination: the single clause that matters most

Subordination is the agreement between the seller and the senior lender that sets when the seller may be paid and what the seller may do about non-payment. It overrides the note itself, and it is negotiated with the bank rather than with the buyer. Sellers who focus on principal and rate, then sign whatever the lender's counsel drafted, have left the economics of the note to someone else.

Payment blockage and standstill periods

A payment blockage provision lets the senior lender stop all payments on the note, interest included, while the borrower is in default or in breach of a financial covenant. A standstill provision separately bars the seller from accelerating, suing or enforcing against collateral.

Blockage periods of 180 days per event are common, and standstill periods of 180 days or longer often sit alongside them. A buyer who trips a covenant in year two can stop paying you while you are barred from acting on it.

What to negotiate in the subordination agreement

Push on four points, in this order of value:

1. A cap on blockage. One blockage period per twelve months, with a maximum number of days, and a bar on using the same covenant breach twice.
2. Interest continues to accrue. Blocked interest should accrue at the note rate or a default rate and become payable once the blockage lifts.
3. A carve-out for permitted payments. Scheduled interest continues unless there is an actual payment default on the senior facility.
4. Notice rights. Written notice of any senior default within a short window.

Sellers who raise these points before the LOI is signed generally get some of them. Sellers who raise them in week eight of exclusivity generally do not, which is one of the ways seller leverage drains away after the letter of intent.

Offset rights, buyer resale and the SBA standby rule

Three further mechanics move real money and sit outside the headline terms. Each is standard enough that its absence from a draft is worth questioning.

Right of offset against indemnity claims

A right of offset lets the buyer reduce payments on the note to satisfy an indemnity claim under the purchase agreement. The note becomes a second escrow, one the buyer controls.

Negotiate it down: limit it to claims finally determined rather than merely asserted, require disputed amounts to sit with an escrow agent, and exclude claims already covered by the escrow or by insurance. The interaction with the indemnity package is set out in reps, warranties and indemnification.

What happens if the buyer resells the business

Most lower middle market buyers are financial acquirers with a hold period shorter than a five-year note. A change-of-control clause requiring repayment in full on a sale of the business is standard, and its absence leaves the seller holding paper issued by a company now owned by a stranger.

Ask for mandatory prepayment on a change of control, on a refinancing of the senior debt, and on a sale of substantially all assets, plus a consent right over assignment of the note to any successor.

Seller notes in SBA-financed deals

Where the buyer uses an SBA 7(a) loan, the standby rules come from the SBA's operating procedures and are not negotiable between the parties. Under SOP 50 10 8, effective 1 June 2025, a seller note counts toward the buyer's required equity injection only if it is on full standby for the life of the SBA loan, commonly ten years, and it may cover no more than half of that injection. SOP 50 10 8.1 succeeded it on 1 October 2026.

Full standby means no principal and no interest for that period. Sellers in SBA deals frequently sign two notes, one on full standby counting toward equity and one on limited standby outside it.

How seller financing in a business sale is taxed

A seller note usually qualifies for installment reporting under IRC §453, which spreads gain recognition across the years the payments arrive rather than taxing it all in the year of sale. The interest component is reported separately as ordinary income.

Three details change the math. Depreciation recapture is recognized in full in the year of sale whether or not a payment was received. Where installment obligations outstanding at year end exceed $5 million in face amount, IRC §453A imposes an interest charge on the deferred tax. A seller can also elect out of the method.

Whether deferral helps depends on the seller's bracket, state of residence and the deal structure. Those variables belong with a CPA, and the structure interacts with the asset deal and share deal choice in ways that can outweigh the deferral benefit.

Worked example: a headline price with a note against an all-cash offer

The following example is illustrative and uses figures typical of the lower middle market. Assumptions: a commercial services business with $12.0M in revenue and $2.0M in adjusted EBITDA, no net debt, two competing offers.

Offer A pays $10.0M in cash at closing, a 5.0x multiple. Offer B pays $11.0M, a 5.5x multiple, with 20% of the price in a five-year subordinated seller note at 7.5%, interest-only, balloon at maturity. The note is valued at a 14% required return, the kind of yield demanded on unsecured junior paper from a small private company.

Now move the required return. At 20%, reflecting a weaker credit or thin buyer equity, the note is worth $1,378,000 and Offer B's advantage falls to $178,000, or 1.8%. Break-even sits near 24%, above which the all-cash offer wins. If the buyer defaults after two interest payments and the seller recovers nothing, Offer B delivers $9,130,000, or 8.7% below Offer A.

Structure moves the number too. The same note amortizing in equal annual payments over five years at the same coupon is worth $1,867,000 at a 14% discount rate. The takeaway: a 10% higher headline is worth 5.1% at a 14% required return and 1.8% at 20%, and switching from a balloon to amortization recovers about $158,000 without moving the price.

When to accept a seller note and when to decline

Accept a note when the cash at close alone clears your number, the buyer has a real balance sheet behind the paper, and the terms compensate you for the risk. Decline when the note is doing work the buyer's equity should be doing. Four conditions should hold together:

• Cash at close is at or above the level you would have accepted from an all-cash bidder, so the note is upside rather than the deal.
• The note is 20% of the price or less, amortizing, secured by a second lien and a pledge of the buyer's equity, with personal guarantees from individual, search fund or sponsor buyers.
• The subordination agreement caps payment blockage, lets interest accrue while blocked, and gives you notice of senior defaults.
• The buyer's financing is committed, with a named lender and a signed commitment letter rather than a term sheet.

The honest reading of the opposite case: when the note is large, unsecured, on full standby, and the cash at close sits below what the next bidder offered in cash, the buyer is telling you they cannot afford the business at the price on the front page. A competitive process makes that visible, because a second bidder's all-cash number is the only reliable benchmark for what the paper is worth. That comparison is one reason running a structured sale process matters more than the highest indicative figure, and it is set up during the exit preparation phase, before any note is drafted.
