Buying a Business With No Money Down: What SBA Rules Actually Allow
Buying a business with no money down: why the SBA 10% injection is a floor, how much a seller note can cover, and what tightens on 1 October 2026.

Short answer: You cannot buy a business with genuinely zero cash using an SBA 7(a) loan, unless you are buying out a co-owner of a business you already part own, which is the one verified exception. SBA requires a minimum 10% equity injection on a change of ownership, and a seller note only counts toward it if the seller agrees to receive nothing at all for the life of the loan, capped at half the injection. From 1 October 2026 the rule gets tighter rather than looser: under SOP 50 10 8.1 the injection on an Initial Acquisition cannot be reduced or eliminated at all. So the honest floor on a $500,000 purchase is about $25,000 of your own money, not zero. Last updated August 2026. Educational only, not financial, legal or lending advice.
Can you buy a business with no money down?
Not with SBA financing, which is how most small US acquisitions get funded. The SBA sets a minimum 10% equity injection on a change of ownership, and that is a floor written into the rulebook rather than a lender preference you can shop around. What you can do is reduce how much of that 10% comes out of your own bank account, using a seller note on full standby for at most half of it. The remaining half has to be real cash or an equity partner.
The reason this question produces so much bad content is that "no money down" is technically true in one narrow case and completely false in the case almost everyone is actually asking about. Buying with none of your own money is possible if someone else puts in the equity, which means an investor, a partner, or retirement funds rolled into the deal. Buying with nobody putting in equity is not possible on an SBA loan, and it is about to become less possible.
What the SBA actually requires, and what changes on 1 October 2026
Two rulebooks matter right now, and which one applies to you depends on the date your lender is issued an SBA loan number, not the date you sign anything. We read both firsthand.
| Requirement | Loan number through 30 Sep 2026 | Loan number from 1 Oct 2026 |
|---|---|---|
| Minimum equity injection | 10% of total project cost | 10%, and for an Initial Acquisition it cannot be reduced or eliminated |
| Seller note counted as equity | Full standby for the life of the loan, no more than half the required injection | Full standby for the term of the loan, with limited sourcing |
| Debt service coverage floor | 1.15:1 historical or projected | 1.25:1 on an Initial Acquisition |
| Projections toward coverage | Permitted | Not applicable to change of ownership transactions |
| 7(a) Small Loan processing | Available at $350,000 or less | Not permitted for any change of ownership |
| Quality of earnings report | Not required | Required where the purchase price is $3,000,000 or more |
Read the second column against the third and the direction is obvious. Every change tightens the deal for a thinly capitalized buyer. The coverage floor rises, you lose the ability to argue coverage from projections rather than history, small loan processing disappears for acquisitions so even a $200,000 deal goes through full underwriting, and the injection stops being negotiable. If you are working on a deal right now, the loan number date is the single most important thing in your timeline, and it is worth asking your lender directly which rulebook they expect to close you under.
The one real exception: buying out a partner
There is a genuine carve-out, and it is the only route we have been able to verify where an SBA borrower can put in less than 10% and sometimes nothing at all. It applies when you already own part of the business and are buying out a co-owner. Under SOP 50 10 8, less than 10% equity may be allowed where the remaining owner or owners certify that they have been active in the business and have held the same or higher ownership interest for at least the preceding 24 months, and the business shows a debt-to-worth ratio no greater than 9:1 before the change. That reading comes from Michelle Sergent Kaas of Starfield & Smith, an SBA lending law firm, writing on 6 May 2025.
Fail either limb and you do not automatically owe the full 10%. You owe the lesser of two figures: cash sufficient to bring debt-to-worth to no greater than 9:1, or cash of at least 10% of the purchase price. On a business with a clean balance sheet the first figure can be far below the second, and the rule takes the smaller one. If you are in this position, our page on buying out a business partner and partner buyout financing sets out the test, the structures and what each one does to the tax.
Note what this exception is not. It is not available to an outside buyer purchasing a business they have no stake in, which is the situation almost everyone means by "no money down". The logic is that the SBA is not underwriting an unproven operator; it is lending to someone who has already run the business for two years.
Can a seller note cover the down payment?
Partly, on terms most sellers dislike once they understand them. A seller note counts toward your required equity injection only if it is on full standby, meaning the seller receives no principal and no interest for the entire term of the SBA loan, and it cannot exceed half the required injection. On a $500,000 purchase with a $50,000 injection, that means at most $25,000 can come from a standby seller note and at least $25,000 must be your cash.
This is where most first-time term sheets fall apart. A seller who agreed to carry twenty percent at eight percent interest with payments starting in month one has agreed to something the lender will not treat as equity at all, and the discovery usually happens during underwriting rather than at the negotiating table. Agree the standby terms before you agree the rate. A seller note is one of three mechanisms that quietly move the price after you shake hands, alongside an earnout and the working capital adjustment, and all three are worth structuring deliberately rather than discovering at closing.
What about the 100% financing offers you see advertised?
Read what is being financed. Most of those offers are one of four things, and only one of them is really zero cash from anybody.
- 100% of the purchase price, not the project cost. Closing costs, the guaranty fee and working capital still get funded from somewhere, and the injection is calculated on the total project.
- Full seller financing with no bank involved. Legitimate, and the SBA rules simply do not apply because the SBA is not in the deal. The trade is that you are negotiating against one person who now holds all the leverage on terms.
- An equity partner or investor. The cash exists, it is just not yours. You are trading ownership for it, which is a real cost that does not appear in the headline.
- Retirement funds rolled into the business. A recognized structure, but it puts your retirement savings behind the business you just bought, which is concentration risk in the most literal sense.
None of these is a trick, and two of them are perfectly sensible ways to buy. What they are not is free. Anyone marketing "zero down business acquisition" as a product is selling one of the four above with the cost moved somewhere you are not looking.
How much cash do you actually need to buy a business?
Work it from the project cost rather than the sticker price. On a $500,000 acquisition financed with an SBA 7(a) loan, the arithmetic below is our own, using the SBA published fee bands and rate caps rather than a lender quote.
| Line | Amount | Where it comes from |
|---|---|---|
| Purchase price | $500,000 | Agreed with the seller |
| Minimum equity injection at 10% | $50,000 | SBA rule, not lender preference |
| Maximum standby seller note toward it | $25,000 | Capped at half the injection |
| Your own cash, floor | $25,000 | The number that cannot be structured away |
| SBA upfront guaranty fee | $11,250 | 3% of the $375,000 guaranteed portion, our math |
| Maximum allowable variable rate | 9.75% | Prime 6.75% plus the 3.0% cap above $350,000 |
The rate line is worth dwelling on, because it is the figure most often misquoted. The SBA does not publish an interest rate. It publishes a maximum spread over a base rate, and the spread depends on loan size: base plus 6.5% at $50,000 or less, plus 6.0% to $250,000, plus 4.5% to $350,000, and plus 3.0% above that. The Federal Reserve H.15 release dated 1 September 2026 put the bank prime loan rate at 6.75%, so today the ceiling on a typical acquisition loan above $350,000 is 9.75%. Any article quoting you a single "SBA rate" is quoting a lender's offer, not an SBA figure. For the full fee ladder and the equity rules in detail, our SBA loan to buy a business guide works through every band, and if your question is specifically how large a deposit to plan for, we cover the SBA loan down payment separately.
What lenders check before they will fund a low-cash deal
When your injection is at the floor, the lender's attention moves to everything else, and three things decide the file. The first is cash flow coverage, which from October has to clear 1.25:1 on an Initial Acquisition using history rather than projections. The second is the quality of the earnings you are buying, which is why a buyer with a thin down payment should expect more scrutiny of add-backs and, above $3,000,000, a mandatory quality of earnings report prepared for the lender rather than for you.
The third is you. SBA lenders pull personal credit on every guarantor, and a weak score is the most common reason a well-structured first acquisition gets declined, usually for reasons the buyer could have fixed months earlier had they known. It is worth understanding exactly what is dragging your personal score down and clearing it before a lender looks, because a file with a marginal injection and a marginal score gets declined on the combination rather than on either one alone.
The better question than "no money down"
Buyers who fixate on minimizing the down payment usually end up overpaying for the business, because a seller who is asked to carry paper on standby for ten years wants compensation for it, and that compensation shows up in the price. A deal bought at a slightly lower price with a conventional injection is frequently cheaper over the life of the loan than a nominally low-cash deal at a stretched multiple.
The more productive move is to reduce the price you are financing rather than the cash you are injecting, and that is a diligence problem, not a financing one. Verify the revenue against bank deposits, test whether the owner add-backs are genuinely non-recurring, and find out how much of the reported profit is really unpaid owner labour you will have to hire back. Every dollar you take off the price takes ten cents off your injection automatically. If you are earlier than that and still choosing a target, our guide to how to buy a business works through the full eight-stage process and what each stage costs.

Frequently asked questions
Can I buy a business with no money down using an SBA loan?
No. SBA requires a minimum 10% equity injection on a change of ownership. At most half of that can be a seller note on full standby, so on a $500,000 deal roughly $25,000 has to be cash or equity from someone. From 1 October 2026, SOP 50 10 8.1 states that the injection on an Initial Acquisition cannot be reduced or eliminated.
How much money do I need to buy a $500,000 business?
Plan on $50,000 as the equity injection, of which at most $25,000 can be a standby seller note, plus roughly $11,250 for the SBA upfront guaranty fee and separate budget for legal, valuation and diligence work. A realistic all-in cash requirement is meaningfully above the injection alone, which is the number most first-time buyers underestimate.
Does a seller note count as a down payment?
Only on full standby, meaning no principal and no interest paid for the life of the SBA loan, and only up to half the required injection. A seller note with a normal payment schedule does not count toward equity at all, regardless of its size.
What is the SBA interest rate for buying a business?
There is no single SBA rate. SBA publishes a maximum spread over a base rate by loan size: base plus 6.5% at $50,000 or less, 6.0% to $250,000, 4.5% to $350,000, and 3.0% above $350,000. With the bank prime loan rate at 6.75% on the Federal Reserve H.15 release dated 1 September 2026, the ceiling on a typical acquisition loan is 9.75%.
Is seller financing a way to buy with no money down?
It can be, when no bank is involved and the seller agrees to carry the whole price, because the SBA rules simply do not apply. In practice sellers rarely accept full carry from an unproven buyer, and when they do the terms reflect the risk they are taking. You are trading cash today for a stronger position for the seller on everything else.
