Seller Financing 101: What Terms Are Actually Market-Standard Right Now#

It's not a favor to the buyer. It's not optional once an SBA loan enters the picture. And it's not the deal your lawyer closed three years ago, the rules underneath it changed in 2025.

Seller financing, sometimes called a seller note, is a loan the seller extends to the buyer to help bridge the gap between the buyer's cash and the total purchase price. Sellers who treat it as a negotiable nicety are often surprised to find their lender treats it as a structural requirement, with its own rules on size, timing, and repayment.

Why a seller note exists in the first place#

A seller note solves three problems at once. It closes the financing gap when a buyer can't source 100% of the price in cash or bank debt. It signals to the lender and the buyer that the seller believes in the business enough to be paid over time instead of entirely at closing. And it can let the seller defer some tax liability across multiple years instead of taking it all in one lump sum.

None of that makes it optional in an SBA-backed deal. It makes it load-bearing.

The rule that changed underneath everyone#

Most of what sellers assume about seller notes is based on the pre-2025 SBA rulebook. Under the current SOP (effective mid-2025), a seller note only counts toward the buyer's required equity injection if it sits on full standby, meaning zero principal and zero interest payments, for the entire SBA loan term. That's typically 10 years, not the 24-month standby window that used to be standard.

That single change reset what "market-standard" means for sellers taking financing on an SBA-backed deal.

What's actually market-standard right now#

Seller note size. SBA 7(a) rules require the buyer to inject at least 10% equity into the deal. A seller note can cover up to half of that, meaning up to about 5% of total project cost. The buyer still has to bring a minimum of 5% in their own verified cash. A seller note covering more than that isn't standard, it's a sign the deal is under-capitalized.

Standby period. Full loan term, typically 10 years, with no payments of any kind during that window. This is the single biggest shift sellers need to plan around financially.

The two-note workaround. Some buyers and their lenders split seller financing into two separate notes: one sized to satisfy the equity injection (full standby, as required), and a second, larger note structured with normal payment terms outside the SBA equity calculation. It's more paperwork, but it gets the seller some cash years sooner than a single note would.

Personal guarantees. If the seller retains 10% or more equity in the business after closing, they're generally required to personally guarantee the SBA loan for a minimum of 24 months. Sellers who plan to roll over equity should know this before they agree to it.

No earnouts. SBA 7(a) rules generally prohibit contingent or performance-based pricing in the transaction itself. If a buyer proposes an "earnout" structured as part of an SBA-financed deal, that's a red flag worth raising with counsel before it goes further.

Subordination. A seller note sits behind the SBA loan in repayment priority, always. Sellers can't negotiate a senior lien position while the SBA debt is outstanding, and shouldn't expect to.

Red flags in a seller note request#

A buyer asking for seller financing above the roughly 5% equity-injection cap, without a clear two-note structure to justify it, usually means the buyer doesn't have the capital the deal requires. A buyer pushing to waive standby, or dressing up an earnout as a "performance-based note," is trying to get SBA-style leverage without SBA-style discipline. Either one is worth a second conversation before signing an LOI.

What this means for sellers right now#

Seller financing isn't a courtesy you extend to close a gap. It's a structural piece of most SBA-backed deals, with rules that shifted meaningfully in 2025. Know the standby period you're actually agreeing to before you agree to it.

FAQ#

Is seller financing required to sell a small business? Not always. Cash buyers and some conventional-financed deals close without it. But in SBA 7(a) deals, which make up a large share of small business acquisitions, a seller note is often part of how the buyer meets the equity injection requirement.

Can a seller note be paid off early? Yes, once the standby period ends and the SBA loan's prepayment penalty period (typically 3 years) has passed, buyers can prepay the note without restriction from the SBA side.

What happens if the buyer defaults on the SBA loan? Because the seller note is subordinate, the SBA lender gets paid first in any default or liquidation scenario. Sellers should assume the seller note is the last dollar recovered, not the first.

Does seller financing change the sale price? It can. Buyers and lenders sometimes price in the extended standby period, and sellers may negotiate a modestly higher headline price to offset years of deferred payment.

Do these standby rules apply outside of SBA-financed deals? No. Conventional bank financing or all-cash deals can structure seller notes with whatever standby and payment terms both parties negotiate directly. The full-standby, 10-year rule is specific to SBA 7(a) transactions.
