How to Buy a Business with No Money Down (The Real Answer)

Let me be direct: you almost certainly cannot buy a business with zero of your own money. The structure that made true zero-down possible (a seller carrying the full equity injection on standby while the buyer brings nothing) is gone. The SBA closed that door in 2025, and on October 1, 2026 it closes the side door that was left: investors covering the whole injection for you.

But the real floor is lower than most buyers realize, and there are legitimate structures that get you surprisingly close to zero. Here is what actually closes in 2026, and what changes on October 1.

The Real Floor: 5% From You, No Matter What

The SBA requires a 10% equity injection on a business acquisition, measured against total project cost (the purchase price plus closing costs and any working capital rolled into the loan), not just the price. Under the current rulebook, SOP 50 10 8, up to half of that can be a seller note on full standby, meaning no payments of principal or interest for the life of the SBA loan.

The new rulebook, SOP 50 10 8.1, takes effect October 1, 2026 and tightens the other half. It sorts injection sources into two buckets. Unlimited sources are cash you did not borrow, a personal loan you can show you will repay from something other than the business, and grants with no clawback. Limited sources are a seller standby note, any other standby debt, and money from non-controlling minority investors. The limited sources, individually or added together, may cover no more than half of the required injection.

Read that carefully, because it is the whole point. The seller can carry 5%. An investor can put in 5%. A seller and an investor together can cover 5%. In every case the other 5% is yours, from unborrowed cash, and there is no structure that changes that. On a $1.5M acquisition you are bringing roughly $75,000 of your own money, and the leanest legitimate deal has someone else covering the other $75,000 on terms the SBA accepts.

The new SOP contains no transition language. If your deal will not fund before October 1, structure it to the new rule now rather than discovering the gap in underwriting.

The Seller Note Conversation Happens at the LOI

This is the single biggest structural mistake I see buyers make. They agree on a purchase price, sign a letter of intent, spend weeks in due diligence, and then raise the seller note conversation after they already have time and money invested. That is the wrong sequence.

Whether a seller will carry on full standby is a deal structure question, not a post-LOI detail. It belongs in the letter of intent. If the seller's answer is no, you want to know that before you invest weeks of due diligence, not after. Raise it early, frame it as a standard structure that demonstrates seller confidence, and give the seller time to consult their advisor before committing.

One structural detail worth knowing: under the new rule, whoever holds the standby note cannot also take an equity stake in the business. A seller either carries paper or keeps a piece, not both.

Investors Can Cover Half, Not All

Today, a buyer with strong operating experience and thin savings can sometimes raise the entire injection from outside investors, with the lender leaning on experience and cash flow to make up for the missing skin in the game. That path closes October 1. From then on, investor money counts toward the injection only as a limited source, so it can replace the seller note's half, or share that half with a seller note, but it cannot replace your half.

The investors also have to fit a definition. Each must be a non-controlling minority investor, meaning under 20% of the equity and no control over the operating business. Their money cannot come with any agreement to be repaid or to receive distributions to recover it before the SBA guaranty is released, and while the loan is outstanding the only distributions they can take are what they need to cover the taxes on their share of the business's income.

Take a borrower acquiring a $1.8M specialty HVAC company. He had 12 years running HVAC operations and $90,000 of his own, which is right at the floor for that price. Two silent investors put in the other $90,000, each taking a minority stake under 20% with no say in operations, and the seller carried nothing. The business DSCR came in at 1.4x and his credit was 710. The deal closed in 41 days. His operating experience is what made a lender comfortable with a buyer sitting exactly at the minimum; the investors are what made the minimum reachable.

The Partial Buyout Exception

There is one scenario where the 10% injection works differently: buying part of a business from an owner who stays on with a minority stake, even a small one. Because you are buying an ownership interest rather than assets, it is structured as a stock purchase, and the departing owner keeps a piece.

Under the current rule, a selling owner who stays with under 20% must personally guarantee the full loan for at least two years after funding. From October 1 the SBA calls this an Owner Buyout, and the rule is simpler and stricter: at least one original owner stays and guarantees the loan regardless of their percentage, and a buyer who is not already employed by the business can take less than 50% and cannot become the largest shareholder, or the deal is treated as a full acquisition with the full 10% that cannot be reduced. The SBA has said that last clause will be adjusted in a technical update, so confirm the current wording on your deal.

What makes this path attractive is the injection itself. For an Owner Buyout, the lender may reduce or even waive the 10% if the business has enough liquidity and working capital to keep operating after the transaction and did not end the last fiscal year with negative net worth. The guarantee is the tradeoff. A seller who agrees to it is demonstrating real confidence in the business they are selling you. A seller who pushes back hard on it is worth examining closely.

This structure comes up most often in internal succession, where a key employee or manager is buying in from the owner. The seller stays on with a small stake, the transition is smoother, the lender has an additional guarantor, and the buyer gets into the deal with the least friction of any structure I see.

Why Lenders Want More Than the Minimum

Hitting your 5% gets you in the door. It does not make the lender comfortable. Active SBA lenders are paying more attention to post-close liquidity than they were two or three years ago, and thin liquidity is what turns a deal that qualifies on paper into a decline in practice.

Most lenders want to see that you have two to three months of operating expenses in reserve after the down payment clears. That does not all have to be your cash. It can include committed capital from partners or investors. But the lender wants to see a cushion that tells them you can weather a slow first quarter without defaulting on a loan you just took out.

Arriving at closing with exactly 5% of the project cost and nothing behind it is a hard sell even when the business cash flow looks clean.

The Premium You Might Pay to Get There

A seller agreeing to carry a 5% standby note is taking real risk. They are behind the bank in any liquidation scenario, and they wait for the SBA loan to be paid off before they see a dollar. The note can accrue interest during the standby period, but none of it is paid until the SBA loan is gone. Plenty of sellers still agree to this, but many will only do it if you pay for the privilege.

It is common to pay a modest premium on the purchase price in exchange for a seller carry on standby. That is the trade: a slightly higher price in exchange for less cash at closing. Run the math on your specific deal. If a $50,000 premium on the purchase price saves you $75,000 in cash at closing, that is a trade worth making for most buyers who are capital-constrained. One caution: if the price runs past what the business valuation supports, the new rule requires the excess to be carried on full standby as well, so a premium is not free money for the seller either.

What Kills These Deals

Planning around zero. That option is gone, and deals built on the assumption that a buyer can bring nothing fall apart early. If a broker or online article is telling you that true zero-down is still available through standard SBA channels, that information is outdated. The same goes for plans built on investors covering the whole injection after October 1.

Weak post-close liquidity. The down payment is the threshold. The cushion behind it is what gets you approved. A lender who sees 5% equity and no reserves is looking at a borrower who cannot absorb any friction in the transition period.

The wrong lender. Some lenders want 15% or 20% as a matter of internal policy regardless of SBA minimums. Submit a 5% buyer-equity deal to one of them and you get a decline after a six-week wait. Knowing which lenders are comfortable with lean equity structures on strong cash flow deals is the difference between a fast approval and a wasted month.
