Seller Financing to Buy a Business

How a seller note is actually structured

Mechanically it's simple: at closing you pay part of the price in cash, and the balance becomes a promissory note payable to the seller, usually secured by the business assets and subordinated to any senior lender. On Main Street deals, notes commonly run 10–30% of the purchase price over three to seven years, with interest somewhere near or modestly above prevailing small-business lending rates. Nothing here is standardized — every term is negotiable, and the terms trade against each other. Sellers who care most about the headline price will usually concede on rate and term; sellers who care most about monthly cash flow will concede on price.

Two structural details matter more than the rate. The first is the amortization schedule: a note that fully amortizes over five years is very different from one with a balloon in year three, and the balloon is what tends to catch buyers who assumed they would refinance. The second is security and position. A seller in second position behind a bank has meaningfully less leverage than one holding the only lien, which is precisely why the seller will negotiate hard on it.

Combining a seller note with SBA financing

This is the workhorse structure of small-business acquisitions: an SBA 7(a) loan for the bulk of the price, a seller note for a slice, and buyer cash for the rest. The complication is standby. The SBA lender takes first position, and where a seller note is being counted toward your required equity injection, it generally must be on full standby — no principal or interest paid for a defined period at the start of the loan term. That is not a formality; it changes the seller's economics substantially and needs to be on the table before you sign an LOI, not discovered during underwriting.

Program specifics change, and individual lenders layer their own policy on top, so treat the standby terms as something to confirm with your specific SBA lender rather than assume. Our companion guide on buying a business with an SBA loan covers the injection rules and underwriting in more detail, and the low-cash structures guide covers how far the combination can actually be stretched.

Why sellers say yes

• A bigger buyer pool. Requiring all cash eliminates most competent operators. Sellers who have already sat on the market for months learn this quickly.
• A higher price. Carrying paper is routinely traded for the asking number. Buyers should note the flip side: a seller-financed deal is often a more expensive deal.
• Tax timing. Installment payments can spread gain across years instead of concentrating it into one. This is a real motivator and worth naming in a negotiation.
• Interest income. The note yields, often better than the alternatives for the proceeds.

It is also worth reading the refusal. A seller who will not carry any paper at all on a business they describe as stable is making a statement about their own confidence, and it is a fair question to ask directly.

What a buyer should negotiate into the note

The terms below are where buyer risk actually lives. The first one is the most important and the most frequently omitted.

How to raise it without blowing up the deal

Bring it up in the letter of intent, not after diligence. Sellers who are surprised by a financing request late in a process usually read it as a renegotiation attempt, and they are often right. Frame it as alignment: a note gives the seller a continuing stake in a clean handoff, which is a genuine argument rather than a talking point. Arrive with a specific proposal — amount, term, rate, standby if SBA is involved — plus evidence that the business's cash flow services it comfortably. And be flexible on price in exchange, because that is the trade the seller is actually being offered. Whatever you agree, verify the earnings that will service the note yourself first; the due diligence checklist covers the tests that matter.
