SBA Equity Injection Rules for a Laundromat Purchase
SBA equity injection rules require at least 10% of total project cost on a complete change of ownership. Seller debt can cover no more than half of that requirement, and only on full standby — no principal, no interest — for the life of the 7(a) loan. Lenders routinely require more than the SBA minimum.
Key takeaways
- 10% of total project cost, not of purchase price. Project cost includes closing costs, working capital, and funded capex.
- A seller note covers at most half the requirement, on full standby for the loan's life (Source: SBA SOP 50 10 8).
- "5% down" is shorthand, not a rule. It only happens when a seller agrees to a full-standby note for half.
- Lenders add overlays. 15-20% plus personal reserves is common for a first-time operator.
- Sources are traced and seasoned. Moving money shortly before application creates work, not flexibility.
The Rule, Precisely
Under SOP 50 10 8, a complete change of ownership resulting in a new owner requires an equity injection of at least 10% of total project cost.
Seller debt may count toward no more than half of that required injection, and only when the seller note is on full standby for the life of the 7(a) loan — meaning no principal and no interest payments during the standby term. The lender must document both the note and the standby agreement in the file.
Note also that SOP 50 10 8.1 is published but does not take effect until October 1, 2026. Guidance describing 8.1 as current today is wrong, and any page modified after that date needs re-checking against the new SOP.
Total Project Cost, Not Purchase Price
This distinction costs buyers real money, and it is the single most common misunderstanding of the rule.
| Line | Example |
|---|---|
| Purchase price | $290,000 |
| Closing costs, guaranty fee, legal, escrow, valuation | $21,000 |
| Working capital funded in the loan | $26,000 |
| Capital spending funded in the loan | $18,000 |
| Total project cost | $355,000 |
| 10% minimum injection | $35,500 |
| Compare: 10% of purchase price alone | $29,000 |
A buyer who budgeted 10% of the price arrives $6,500 short before a lender has applied a single overlay.
The Seller-Note Provision
On the example above, the required injection is $35,500 and a qualifying seller note can cover at most $17,750.
| Structure | Buyer cash | Seller note on standby |
|---|---|---|
| All cash injection | $35,500 | $0 |
| Maximum seller note | $17,750 | $17,750 |
| Partial seller note | $25,500 | $10,000 |
Two things a seller must understand before agreeing:
Full standby means no payments. For a ten-year loan, that is ten years with no principal and no interest received. A seller planning to fund retirement from note payments has agreed to the wrong instrument.
It is subordinate. In a default, the bank is paid first. The note's value depends entirely on the business performing.
A seller note beyond the injection cap is not injection at all. It is separate subordinated debt behind the bank, on whatever terms the lender will permit — which is a different negotiation with different economics. See seller financing for laundromats.
Where the Injection Can Come From
| Source | Generally acceptable? | Documentation the lender wants |
|---|---|---|
| Buyer savings and checking | Yes | Two to three months of statements showing the funds seasoned |
| Brokerage or retirement account (liquidated) | Yes | Statements plus evidence of the transfer and any tax treatment |
| Gift from a family member | Commonly | Gift letter confirming it is not a loan, plus the donor's source |
| Sale of another asset | Yes | Closing statement or bill of sale, plus deposit evidence |
| Home equity loan or HELOC | Sometimes, lender-dependent | Loan documents; note the lender will count the payment in your debt load |
| ROBS structure | Yes, with specialist administration | Plan documents, valuation, and ongoing compliance |
| Qualifying standby seller note | Up to half the requirement | The note plus an executed standby agreement |
| Undocumented cash | No | — |
| A loan from a third party secured by the business | No | — |
Sourcing and seasoning is the practical friction. Lenders trace where injection funds came from, and they want to see them sitting in an account rather than arriving the week before closing. Consolidate your injection into one account early in the process and stop moving it. Buyers who shuffle funds between accounts to make a balance look better create weeks of documentation work.
What Lenders Add On Top
The SBA sets a floor. The lender sets the requirement.
Common overlays for a laundromat acquisition:
- A higher injection percentage. 15% to 20% is routine for a first-time operator with no industry experience.
- Post-closing liquidity. Cash the lender wants to see remaining after the injection and closing costs — often three to six months of personal living expenses plus a business reserve.
- Restrictions on the injection source. Some lenders will not count a HELOC; others will, but will include the payment in your debt-to-income analysis.
- Debt service coverage above the minimum. Many apply a 1.25 threshold, computed after a market-rate salary for whoever runs the store and after striking add-backs without source documents.
The practical instruction: ask your lender for their actual injection requirement and their reserve expectation in the first conversation, not after you have signed an LOI.
Worked Example
| Line | Amount |
|---|---|
| Total project cost | $355,000 |
| SBA minimum injection at 10% | $35,500 |
| Lender's requirement at 15% | $53,250 |
| Maximum qualifying standby seller note (half of $35,500) | $17,750 |
| Buyer cash if the seller agrees to the maximum note | $35,500 |
| Buyer cash if the seller agrees to no note | $53,250 |
| Plus repair reserve held outside the loan | $12,000 |
| Plus personal reserves the lender wants remaining | $18,000 |
| Realistic cash position needed | $65,500 to $83,250 |
Illustrative. Note the spread: whether the seller agrees to a standby note moves the buyer's cash requirement by nearly $18,000, which is why the question belongs in the LOI rather than in underwriting.
For context on scale, the median laundromat sold for $250,000 across 855 reported transactions for 2021-2025 (Source: BizBuySell), so the example above is a modestly above-median deal.
Common Mistakes
- Budgeting 10% of the purchase price. The base is total project cost.
- Assuming a seller note covers the whole injection. It covers half of the requirement at most.
- Agreeing to a seller note without specifying standby. Two parties agreeing to different instruments.
- Planning to the SBA minimum. The lender's number is the one that matters.
- Moving injection funds around late. Season them in one account and leave them.
- Forgetting reserves. A lender that sees you emptied every account to close is a lender looking for a reason to decline.
Negotiating the Standby Note With a Seller
Because the seller-note provision moves the buyer's cash requirement so much, it is worth knowing how the conversation actually goes.
What the seller hears: "Would you carry part of the price?" — which most sellers interpret as an amortizing note paying monthly interest.
What is actually being asked: a note that pays nothing at all for the full life of the buyer's loan, subordinate to the bank, secured only by whatever the lender permits.
Those are different enough that the conversation has to be explicit, and it has to happen at LOI stage rather than in underwriting. Three things make it more likely to succeed:
- Frame it as part of the total price, not as a discount. A seller receiving $290,000 with $17,750 deferred is being paid in full, later.
- Explain what it buys them — a buyer whose file clears underwriting, rather than a buyer who withdraws in week eight for lack of injection.
- Offer terms on the deferred portion that reflect the wait: a higher rate accruing during standby, if the lender permits it, or a balloon at maturity.
And be honest about the seller's risk. They are financing the buyer's upside on performance they no longer control, behind a bank. A seller who needs the money for retirement income should decline, and a broker who does not say so is not doing the job.
Summary
Ten percent of total project cost, a seller note for at most half of that on full standby, funds sourced and seasoned, and a lender requirement that is usually higher than the floor. Compute the base correctly, settle the seller-note question at LOI stage, and consolidate your injection early. Those four steps prevent most of the injection problems that surface in underwriting.

Frequently Asked Questions
How much equity injection does SBA require on a laundromat?
At least 10% of total project cost on a complete change of ownership resulting in a new owner, under the current SOP 50 10 8. Total project cost means purchase price plus closing costs, working capital, and any capital spending funded in the loan — not the purchase price alone.
Can a seller note cover the whole down payment?
No. Seller debt can count toward no more than half of the required injection, and only when it is on full standby for the life of the 7(a) loan, with no principal or interest paid during that term. The lender must document the note and the standby agreement.
Is 5% down ever allowed?
Not as a simplification of this rule. The 10% requirement stands, and the seller-note provision reduces the buyer's cash to as little as 5% of the project — which is where the misleading shorthand comes from. That is only true when a seller agrees to a full-standby note for half the requirement, which many will not.
Where can the injection come from?
Buyer savings, brokerage assets, a gift with proper documentation, a home-equity loan in some cases, a ROBS structure, or a qualifying standby seller note for up to half. Lenders trace the source and want funds seasoned in an account, so moving money around shortly before application creates work rather than avoiding it.
Do lenders require more than the SBA minimum?
Frequently, yes. The SBA sets a floor and lenders apply their own credit overlays on top — commonly 15% to 20% from a first-time operator, plus personal reserves they want to see remaining after closing. Ask your lender for their actual requirement rather than planning around the program minimum.
