Can a Seller Note Count Toward an SBA Down Payment?
Yes, but only partly. A seller note can count toward no more than half of the required SBA down payment — the equity injection — and only when it is on full standby, with no principal and no interest, for the life of the 7(a) loan (Source: SBA SOP 50 10 8). The lender must document both the note and the standby agreement.
Key takeaways
- Half the requirement, maximum. On a $35,500 required injection, at most $17,750 from a seller note.
- Full standby means zero payments for the life of the loan — ten years on a typical acquisition.
- The injection base is total project cost, not purchase price.
- A note beyond the cap is not injection. It is separate subordinated debt requiring lender approval.

The Short Answer
Up to half the required injection, on full standby, documented by the lender. That is the whole rule.
The Arithmetic
| Line | Example |
|---|---|
| Purchase price | $290,000 |
| Closing costs and fees | $21,000 |
| Working capital | $26,000 |
| Funded capital spending | $18,000 |
| Total project cost | $355,000 |
| Required injection at 10% | $35,500 |
| Maximum qualifying seller note | $17,750 |
| Minimum buyer cash | $17,750 |
Note the base. The injection is calculated on total project cost, not on the purchase price, which is why the dollar figure is larger than most buyers first assume.
What Full Standby Actually Means
No principal. No interest. No payments of any kind, for the entire life of the 7(a) loan.
For a ten-year acquisition loan, that is ten years during which a seller who agreed to "carry a note" receives nothing on it. Interest may accrue depending on how the note is drafted and what the lender permits, but cash does not move.
This is the single most common misunderstanding between buyers and sellers in SBA-financed laundromat deals. A seller hears "would you carry part of the price" and pictures a monthly payment. A buyer means an instrument that pays nothing for a decade.
Settle it at LOI stage, in writing, using the word "standby."
Two Different Seller Notes
| Standby injection note | Subordinated amortizing note | |
|---|---|---|
| Counts toward injection | Yes, up to half the requirement | No |
| Payments during the SBA loan | None | Per its terms, subject to lender approval |
| Lender documentation | Note plus executed standby agreement | Note plus subordination agreement |
| Purpose | Reduces the buyer's cash requirement | Bridges a price gap |
| Seller's cash flow | Nothing until the SBA loan is repaid | Depends on approved terms |
A deal can include both, and many do: a standby note covering half the injection, plus separate subordinated debt bridging price. They are different instruments with different risk and different tax timing, and each needs to be named specifically rather than lumped together as "seller financing."
For Sellers Weighing It
The case for: it makes the buyer's file work. A seller receiving the full price with a portion deferred is being paid in full, later. The realistic alternative is often a buyer whose injection is short and whose file does not close.
The case against: you are financing a buyer's upside on performance you no longer control, subordinate to a bank, with no payments for a decade. If the business fails, the bank is paid first.
The honest test: do you need this money as income in the next ten years? If yes, decline, and say so at LOI stage rather than at closing. A broker who does not raise that question is not doing the job.
What to Do Next
Buyers: compute your injection on total project cost, then ask your lender for their actual requirement — the SBA's 10% is a floor and overlays are common. Sellers: if a standby note is being discussed, get the term "full standby" into the LOI and have your CPA model what a decade of deferral does to your after-tax proceeds.

Frequently Asked Questions
How much of the down payment can a seller note cover?
No more than half of the required equity injection, and only when the note is on full standby for the life of the 7(a) loan. On a project requiring a $35,500 injection, at most $17,750 can come from a qualifying seller note, leaving $17,750 in buyer cash before any lender overlay.
What does full standby mean?
No principal and no interest payments for the entire life of the SBA loan. On a ten-year loan, the seller receives nothing on that note for ten years. The lender must document the note and an executed standby agreement in the file.
Can I have a second seller note that does pay?
Potentially, but it is not injection. Any seller note beyond the injection cap is separate subordinated debt behind the bank, on whatever terms the lender will permit. It has different economics and different risk, and the lender must approve its terms.
Why do sellers agree to this?
Because it makes the buyer's file work. A seller receiving a full price with a portion deferred is being paid in full, later, and the alternative is often a buyer who cannot close. A seller who needs the money as retirement income should decline, and should say so early rather than at the closing table.
