Key takeaways
- A seller standby note is a seller-financed loan, subordinated to the senior lender, on which the seller receives no principal and usually no interest until the senior loan is repaid.
- Under SOP 50 10 version 8.1, effective October 1, 2026, seller debt on full standby for the term of the 7(a) loan, other full-standby debt, and non-controlling minority equity below 20 percent may together provide no more than half of the required equity injection.
- Agree the standby terms in the letter of intent; a standby introduced at closing, to a seller who was promised monthly payments, is where financed deals die.
- Subordination puts the seller behind the lender in priority, while full standby also suspends the seller's payments, so do not promise a seller one when the lender requires the other.
- Under version 8.1 a seller note must be in place and current, not on standby, for 36 months after the change of ownership before it may be refinanced, up from 24 months under version 8.
A standby note is a subordinated seller note whose payments are suspended, by agreement with the senior lender, until the senior loan is repaid.
What is a seller standby note?
A seller note is a loan from the seller to the buyer for part of the purchase price, written as a promissory note with its own rate, term, and payment schedule. A standby note is a seller note on which the seller has agreed to receive nothing, or nothing but interest, for a defined period while a senior lender is repaid first.
The standby exists for the senior lender's benefit. A bank or an SBA lender advancing most of the price does not want the seller taking cash out of the business ahead of it, and does not want a second creditor able to force a default while its own loan is outstanding. The standby agreement subordinates the seller's claim and, on full standby, suspends the seller's payments entirely.
Why do SBA lenders ask for full standby?
Because under SOP 50 10 version 8.1, the program's origination rulebook effective October 1, 2026, a seller note that is subordinated to the lender and on full standby for the term of the SBA loan can count toward the buyer's required equity injection. Seller notes, other standby debt, and investors below 20 percent may together supply no more than half of it. Full standby means no principal and no interest to the seller until the SBA loan is repaid. Interest may accrue, be added to the note, and be paid after the SBA loan is repaid.
That makes the standby note a way to close the gap between the cash a buyer has and the cash the program requires. It also makes it a genuine sacrifice for the seller, who is being asked to wait as long as 10 years for money they would otherwise receive at closing. A buyer who treats the standby as a formality will lose the seller the moment the seller's lawyer explains what it means.
What is the seller actually giving up?
Three things. Time, because the note may not pay for the life of the senior loan. Priority, because the senior lender is repaid first in any liquidation and the seller's note is behind it. And bargaining power, because a seller whose note is on standby cannot use a missed payment to pressure the buyer, since there is no payment to miss.
In exchange the seller gets a closed sale, a higher price than an all-cash buyer would pay, and installment treatment of part of the proceeds, which a tax adviser has to review. The seller financing guide lists the terms that belong in any note; a standby note carries all of them plus the subordination and standby language the senior lender will provide.
When should standby terms be agreed?
In the letter of intent, before either side has paid a lawyer. A standby agreement introduced at closing, after a purchase agreement that promised the seller monthly payments, is where financed deals die. The seller has already told their family and their accountant what they are getting. Asking them to wait a decade for part of it, on the day the money was supposed to arrive, reads as a trick even when it is not.
The letter of intent page shows where the financing structure sits in the document. The sentence to include is plain: the seller note will be subject to a standby agreement in the form the senior lender requires, with no payments to the seller until the senior loan is repaid, and the price reflects that. A seller who cannot accept that sentence in the LOI would not have accepted it at closing either, and it is better to learn that before diligence.
How does a standby note change the price?
It raises it, usually. A seller who carries part of the price and waits for it is lending money on terms no bank would offer, and sellers know it. The buyer's answer is that the standby is what makes the senior loan possible at all, and that without it the deal is smaller or does not happen. Both are true. The price that results is a negotiation, and the buyer's job is to make sure the higher price still clears the debt coverage check with a real owner salary in it, because the standby note is still a debt the business will eventually pay.
What is the difference between standby and subordination?
Subordination puts the seller behind the senior lender in priority: if the business is liquidated, the lender is paid first. Standby goes further and suspends the seller's payments for a period. A note can be subordinated and still pay the seller monthly. A note on full standby is subordinated and pays nothing. Lenders use the two terms carefully, and a buyer who conflates them in a negotiation will promise the seller something the lender then refuses.
What changes on October 1, 2026?
SOP 50 10 version 8.1 takes effect that day. It keeps full standby for the term of the 7(a) loan as the condition for a seller note to count as equity, and keeps the half limit, now shared with other standby debt and investors below 20 percent. It lengthens the wait before a seller note that is paying, not on standby, can be refinanced with SBA money, from 24 months after the purchase to 36. SBA Information Notice 5000-880695 applies version 8.1 to applications issued an SBA loan number on or after October 1, 2026, and keeps version 8 for applications submitted through September 30, 2026, so ask the lender in writing which version governs your loan before you write the standby terms into the letter of intent.
Questions people ask next
Does the seller earn interest on a standby note?
On full standby, no payments of principal or interest are made until the senior loan is repaid, though interest may accrue depending on the note. Partial standby arrangements, where interest is paid, exist but do not count the same way toward the injection.
What is SBA Form 155?
The standby creditor's agreement SBA lenders use to document the seller's standby. The lender supplies the form; the buyer's job is to have the seller agree to its substance in the letter of intent.
Can the seller enforce the note during standby?
Not for missed payments, because there are none. The seller keeps the note and its security position behind the senior lender, and is paid when the senior loan is repaid or refinanced.
Why would a seller agree?
For a closed sale at a higher price than a cash buyer would pay, and for installment treatment of part of the proceeds, which a tax adviser has to review. Sellers who need the cash at closing generally will not agree, and it is better to learn that before diligence.
