Seller Notes in Business Sales: When to Take Back Paper and When to Refuse

You have negotiated a $4M purchase price. The buyer proposes $3M cash at close and a $1M seller note payable over five years at 6% interest.

Sounds reasonable. You are getting $4M total, plus interest. The buyer seems credible. Your advisor has reviewed the financials and the buyer’s business plan looks solid.

Here is what that seller note actually means: you are lending the buyer $1M, unsecured and subordinated to any senior lenders, to buy your own business. If the business fails, or if the buyer mismanages it, or if market conditions turn, you are last in line to collect. The bank gets paid first. Employees get paid. Vendors get paid. You get paid if anything is left.

That is not necessarily a reason to refuse the note. It is a reason to understand exactly what you are agreeing to.

A seller note in a business sale is a portion of the purchase price that the seller finances, essentially a loan from seller to buyer, paid over time with interest. Seller notes are most common when buyers cannot fully finance the acquisition through bank debt and equity, typically in transactions with individual, search-fund, or SBA borrowers. The seller note is almost always subordinated to senior lenders, meaning the seller collects only after all other debt is paid in a default scenario.

Key Takeaways

• A seller note is the seller financing a portion of the purchase price, you become a lender to the buyer.
• Seller notes are subordinated to senior debt (SBA loans, bank financing), meaning you are last to collect in a default.
• Seller note interest rates typically range from 5-8% in current market conditions, with 5-7 year terms.
• SBA transactions legally require seller notes in many structures, this is different from a negotiated choice.
• The risk of a seller note is correlated with the buyer’s business management quality, not the business’s historical performance.

Why Seller Notes Exist

Buyers in the lower middle market face a financing gap. The business costs $4M. A bank will lend $2.5M (SBA or conventional). The buyer has $800K in equity. That leaves $700K unfunded.

The seller note fills the gap.

From the buyer’s perspective, the seller note is attractive: cheaper than equity, flexible terms, and a lender (the seller) who has strong incentive to see the business succeed. From the seller’s perspective, the note is a risk-adjusted way to complete a deal that might not close otherwise, at a price that often would not be achievable with all-cash financing.

The challenge is that sellers sometimes agree to seller notes without fully understanding the risk profile, specifically the subordination issue and what happens in a default scenario.

SBA Transactions and Required Seller Notes

One specific context worth understanding: SBA 7(a) loans. In SBA transactions, the seller note structure is often mandated by SBA guidelines as part of the deal structure.

SBA lending rules in certain transaction structures require the seller to demonstrate confidence in the business by leaving some consideration in the form of a note, the logic being that if the seller believes in the business’s future performance enough to accept deferred payment, the SBA has more confidence in the quality of the business being acquired.

In SBA transactions, the seller note is typically on “standby” for a period, meaning the seller cannot receive principal payments for 24 months or more. Interest may or may not be payable during standby, depending on negotiated terms. This is more restrictive than seller notes in non-SBA transactions and sellers should understand the standby requirements before agreeing to SBA deal structures.

The Subordination Reality

When a buyer acquires your business with bank debt and a seller note, the priority waterfall in a default scenario looks like this:

1. Senior secured lenders (bank, SBA lender), first payment priority

2. Any middle-market or mezzanine lenders

3. Seller note, paid only after all senior and mezzanine obligations are satisfied

4. Equity holders, if anything remains

This means that if the business performs poorly after the acquisition, which can happen due to integration problems, management issues, market changes, or factors the seller could not control, the seller note may not be fully recovered.

The historical performance of the business under your management is not predictive of its performance under a new, less experienced operator. This is the core risk of the seller note: you are lending against the buyer’s ability to manage the business, not against the track record you built.

When Seller Notes Make Sense

Despite the risks, seller notes can be the right structure in the right circumstances.

When the buyer is a strong operator. An experienced operator buying their second or third business with a track record of successful acquisitions is meaningfully less risky than a first-time buyer. Buyer quality is the primary risk variable.

When the seller note is a small percentage of total consideration. A $300K seller note on a $4M transaction ($7.5% of deal value) is very different from a $1.5M seller note on a $4M transaction (37.5%). The smaller the percentage, the more acceptable the risk.

When the seller note earns strong interest. A 7-8% note over 5 years earns meaningful return on a risk-adjusted basis if the buyer quality justifies the risk.

When the alternative is a lower all-cash price. If accepting a $300K seller note allows the seller to achieve $4M versus $3.5M all-cash, the incremental $200K after note risk may be worth taking.

Negotiating Seller Note Terms That Protect You

Interest rate. 5-8% is the typical market range in current conditions. Do not accept significantly below market, the note rate should reflect the risk and opportunity cost of your capital.

Personal guarantee. Try to obtain a personal guarantee from the buyer on the seller note. This subordinates the note to senior lenders in the business but gives the seller recourse against the buyer’s personal assets.

Security. Negotiate for a security interest in the assets of the business as collateral for the seller note, subordinated to senior lenders. This does not move you ahead of the bank in a default, but it strengthens your position relative to having no security interest.

Accelerator provisions. Include events that accelerate the full note balance due, default on senior debt, sale of the business, material breach of the purchase agreement.

No standby on interest. In non-SBA transactions, push to receive interest payments from day one rather than having all payments deferred.

Frequently Asked Questions

What is a seller note in a business sale?

A seller note is a portion of the purchase price that the seller finances, essentially a loan from the seller to the buyer, paid over time with interest. The seller becomes a lender in the transaction and carries the risk of the buyer’s performance after closing.

Are seller notes common in lower middle market transactions?

Yes. Seller notes appear in 30-50% of lower middle market transactions involving individual buyers, search funds, and SBA borrowers. They are less common in PE transactions where buyers have access to institutional financing.

What happens to the seller note if the buyer’s business fails?

The seller note is subordinated to senior lenders, meaning the bank and any other senior debt holders are paid before the seller. In a worst-case scenario, the seller may receive partial or no payment on the note.

What is a fair interest rate on a seller note?

Typically 5-8% in current market conditions. Rates reflect the risk of the note (subordinated, unsecured), the transaction structure, and market rates. Significantly below-market rates disadvantage the seller without commensurate benefit.

Should I require a personal guarantee on a seller note?

Yes, when possible. A personal guarantee from the buyer gives the seller recourse against the buyer’s personal assets in a default, which provides meaningful additional protection beyond the business collateral alone.
