The honest answer: You can't buy a business with literally zero dollars. SBA's SOP 50 10 8 requires a 10% equity injection, and the buyer must bring at least half of it in cash. So "no money down" really means a ~5% cash floor, about $50,000 on a $1,000,000 deal. A full-standby seller note can cover the other 5%. Below is the full stack, line by line.
Where the "no money down" myth comes from
The phrase isn't a total lie, it's just missing an asterisk. Compared to buying real estate (20 to 25% down) or starting from scratch (100% of your time and savings), an SBA acquisition really does let you control a $1M cash-flowing business for a fraction of its price. The bank's money does the heavy lifting. But "a fraction" is not "nothing," and the buyers who show up expecting to bring $0 get a rude surprise at underwriting.
Let's replace the slogan with a spreadsheet.
The capital stack on a $1,000,000 deal
Here's a clean, realistic structure for a $1,000,000 business acquisition under current SBA rules. The purchase price plus a modest working-capital and closing allowance is the total project; the sources below have to add up to it.
| Source | Amount | % of price | Notes |
|---|---|---|---|
| SBA 7(a) loan | $900,000 | 90% | Bank's money, ~10-yr term, WSJ Prime + spread |
| Buyer cash injection | $50,000 | 5% | Your own money, the hard floor |
| Seller note (full standby) | $50,000 | 5% | Counts toward injection; Form 155, no payments |
| Total to buy | $1,000,000 | 100% | Plus a separate working-capital cushion |
Notice the two 5% slices. Together they form the required 10% equity injection. The seller note handles one half; your cash handles the other. That's the mechanism behind "low money down", and the reason it can't legitimately go below the 5% cash line.
How the seller note does the heavy lifting
The full-standby seller note is the single most useful tool for lowering your cash. Because it can count toward up to half of the 10% injection, and because on full standby it makes no payments for the life of the SBA loan, it both reduces your cash and keeps your DSCR healthy. The seller is effectively financing 5% of the price while the note sits frozen on Form 155.
This is why deal structure matters more than deal price for a cash-light buyer. A slightly higher price with a generous standby note can require less of your money than a lower price with an all-cash injection.
Why the seller says yes
A motivated seller, especially a retiring owner in the silver-tsunami wave, often prefers a standby note to no sale at all. It also signals they believe the business will keep performing after they leave.
The costs "no money down" pitches leave out
The injection isn't the only cash you need. Budget for these too, or you'll close the deal and immediately be short:
- Working capital. Payroll, rent, and suppliers don't pause on day one. Many deals fold a working-capital line into the SBA loan, but you want a personal cushion regardless.
- Closing costs. SBA guaranty fee, legal, and diligence expenses. These are real dollars, often several thousand and up.
- Living expenses. Your DSCR math should reserve an owner's salary, but you still want savings for the bumpy first months.
A useful rule of thumb: the 5% injection is the entry ticket; a healthy buyer also has a reserve on top so a slow first quarter doesn't become a crisis.
Don't drain yourself to the last dollar
Bringing exactly 5% and nothing else is fragile. The strongest buyers hit the injection and keep a reserve. Being cash-light is fine; being cash-empty on day one is dangerous.
The bottom line
"No money down" is really "as little of your own money as the SBA allows", and that floor is about 5% in cash, plus a sensible reserve. On a $1M business, that's roughly $50,000 to control a company earning six figures, with the bank funding 90% and the seller often bridging the rest. That's not a gimmick. It's one of the best-leveraged deals in America, once you drop the fantasy of literally zero and run the honest numbers.

Frequently asked questions
Not literally with zero. SBA requires a 10% equity injection and the buyer must bring at least half in cash, so the honest floor is about 5% of the price in your own money. A full-standby seller note can cover the other 5%.
Plan on roughly 5%, about $50,000, in your own cash, plus a working-capital and closing-cost reserve. A full-standby seller note can supply the other 5% of the required injection.
A seller note on full standby can count toward up to half of the SBA's 10% injection. The seller effectively finances 5% of the price, so you bring 5% in cash instead of the full 10%.
