Seller financing with an SBA 7(a) loan
Pairing a seller note with an SBA 7(a) loan is the workhorse structure for acquisitions. Get the standby rules right and the seller note can cover part of your required equity injection — bring the wrong note and it counts for nothing. Here is exactly how the SBA treats it.

How a seller note stacks with the 7(a)
An SBA 7(a) business acquisition needs a 10% equity injection on total project costs — purchase price plus fees, working capital, and closing costs. A seller note can fill part of the price the SBA loan does not cover, and a portion of it can even count toward that injection. But the SBA only gives a seller note injection credit when it sits on full standby.
On full standby, a seller note can carry half your injection.
The standby rules that decide everything
Whether a seller note counts toward the injection comes down to one thing: how the seller gets paid while the SBA loan is outstanding.
| Full lifetime standby | No principal and no interest paid for the life of the SBA loan, on SBA Form 155. Counts toward the equity injection — up to half of the 10%. |
|---|---|
| Partial / 2-year standby | Older guidance allowed a 2-year standby to count. Current SOP requires full standby for injection credit, so a short standby note is treated as financing, not injection. |
| Note that takes any payments | Counts for nothing toward the injection. It is ordinary acquisition debt that the lender folds into your debt-service coverage. |
| Cap on the credit | Even on full standby, a seller note can cover at most half of the required injection — 5 of the 10 points. |
How much a seller note can cover
Run it on a $1.5M all-in acquisition. The injection is 10%, or $150,000. A seller note on full standby can cover up to half of that — $75,000 — so you bring the other $75,000 in real cash. The seller can carry more of the price beyond the injection, but those dollars take payments and count as financing the lender underwrites, not as equity.
| Total project costs | $1,500,000 |
|---|---|
| Required equity injection (10%) | $150,000 |
| Max from a full-standby seller note | $75,000 (half the injection) |
| Real cash you must bring | $75,000 (the other 5%) |
| Beyond the injection | A seller note can fund more of the price, but as ordinary debt — not injection |

Common questions
Can a seller note count toward the SBA equity injection?
Yes, but only on full standby. Under SOP 50 10 8 a seller note counts toward the 10% equity injection only when no principal or interest is paid for the life of the SBA loan, documented on SBA Form 155, and only for up to half of the required injection. The other half must be the buyer's real cash or assets.
How much of an SBA deal can a seller note cover?
Toward the equity injection, a seller note on full standby can cover up to half of the 10% requirement — so up to 5% of total project costs. A seller note can fund a larger slice of the price beyond that, but anything that takes payments counts as ordinary debt, not equity injection.
What is full standby on a seller note?
Full standby means the seller receives no principal and no interest for the entire life of the SBA loan — often 10 years. Interest may accrue, but nothing is paid until the SBA loan is retired. A note on partial standby, or one that pays interest, does not count toward the equity injection.
Is a 2-year standby enough for the seller note to count?
Not anymore for injection purposes. Older guidance let a 2-year standby seller note count toward equity. Current SOP 50 10 8 requires full standby for the life of the loan for the note to count toward the 10% injection. A 2-year standby note can still help cash flow, but it is treated as financing, not injection.
Does a standby seller note lower my cash at closing?
Yes. If a seller note on full standby covers 5% of the project, you only have to bring the remaining 5% in real cash to satisfy the SBA injection — though you should still budget for the SBA guaranty fee, closing costs, and a working-capital cushion on top.
Can I use a seller note for an SBA partner buyout?
Yes. In a partner buyout a seller note can count toward the equity injection on the same full-standby, half-of-injection terms, and a true zero-down buyout has its own 24-month active-ownership and 9:1 debt-to-worth rules. See the partner buyout guide for the specifics.
AI summary
When a seller note is combined with an SBA 7(a) acquisition loan, it counts toward the SBA's 10% equity injection only on full standby — no principal or interest paid for the life of the SBA loan, documented on SBA Form 155 — and only for up to half of the required injection. On a $1.5M deal the injection is $150,000, of which a full-standby seller note can cover up to $75,000, leaving the buyer to bring the other $75,000 (5%) in real cash. A seller note that takes any payments, or sits on only a short partial standby, is treated as ordinary financing, not equity injection.
