Most buyers know they'll need a 10% down payment for an SBA acquisition. What they often overlook is how closely lenders examine where that money came from.
Having enough cash in your account is only part of the requirement. Your lender also needs to verify the source of those funds and review how long you've had them.
We've seen buyers with sufficient cash run into financing problems because they couldn't provide the documentation needed to verify their equity injection.
When that happens late in the acquisition process, buyers may have to restructure the financing or risk losing the deal.
The 10% Requirement Applies to Total Project Costs
Under SBA SOP 50 10 8, which took effect June 1, 2025, a change-of-ownership transaction requires a minimum equity injection of 10% of total project costs, not just the business purchase price.
Total project costs can include:
- Business purchase price
- Working capital
- Closing costs
- SBA guaranty fees
- Lender and professional fees
- Inventory or equipment included in the financing
For example, consider a $2 million acquisition with:
| Expense | Amount |
|---|---|
| Business purchase price | $2,000,000 |
| Working capital | $75,000 |
| Closing costs and fees | $60,000 |
| Total project costs | $2,135,000 |
| Required 10% equity injection | $213,500 |
In this example, the buyer needs $213,500 rather than $200,000.
That additional $13,500 needs to be accounted for before moving forward with the acquisition.
Depending on the transaction, buyers who calculate their equity injection using only the purchase price can find themselves $15,000–$40,000 short of the actual requirement.
It's important to calculate the full project cost before submitting an LOI. Our deal affordability calculator can help you estimate the cash required for your acquisition.
Why Lenders Review the History of Your Funds
SBA guidelines require lenders to retain at least 30 days of account statements showing the buyer's available funds.
In practice, many lenders request 60–90 days of statements, particularly for larger acquisitions.
During this review, underwriters look for unusual deposits, transfers, or other activity that needs additional explanation.
For example, if your account typically has transactions around $6,000 and suddenly receives a $90,000 deposit, your lender will likely ask where that money came from.
Simply explaining that the funds are savings generally isn't enough.
You may need to provide:
- Statements from the account where the money originated
- Records showing the transfer between accounts
- Documentation confirming that funds received from another person are not loans
This can become an issue when buyers move money between accounts shortly before closing.
Even when the funds are legitimate, transferring large amounts without maintaining clear records can create unnecessary delays.
If possible, avoid moving your equity funds between accounts once you're actively working on an acquisition. If you need to consolidate accounts, do it early and keep documentation of every transfer.
Acceptable Sources of Equity Injection
SBA guidelines identify several sources that may qualify toward the required equity injection.
1. Personal Savings and Investments
Funds held in personal checking, savings, or brokerage accounts can generally qualify as long as they are not borrowed.
If you're selling investments to fund your acquisition, the lender will want documentation showing the sale and the transfer of proceeds into your bank account.
This can include trade confirmations, settlement records, and bank statements.
Liquidating investments early gives you more time to establish a clear history of the funds before closing.
2. Proceeds From Selling Personal Assets
Money received from selling personal assets may also qualify.
Examples include:
- Real estate
- Vehicles
- Cryptocurrency
- Ownership interests in another business
Lenders will generally require the executed sale agreement and evidence that the proceeds were deposited into your account.
If the asset was sold to a related party, an independent valuation may also be required.
Transactions involving related parties receive additional scrutiny to confirm the sale price is reasonable.
3. Retirement Funds Through a ROBS
A Rollover for Business Startups (ROBS) allows buyers to use eligible retirement funds, such as 401(k) or IRA assets, to fund an acquisition through a properly structured retirement plan arrangement.
When structured correctly, the funds can be converted into equity without triggering a taxable retirement distribution.
However, the arrangement must comply with applicable IRS and Department of Labor requirements.
Lenders may request:
- Retirement plan documents
- IRS determination letters
- Form 5500 filings
Because of the compliance requirements, buyers should work with a provider experienced in structuring ROBS transactions rather than attempting to set one up independently.
4. Documented Gifts
Gifted funds can qualify toward the equity injection, but lenders need more than a gift letter.
The documentation generally includes:
- A signed gift letter confirming there is no repayment obligation
- Evidence that the donor had the funds available
- Records showing the transfer from the donor's account to the buyer's account
The SBA specifically states that a gift letter or promissory note alone is not sufficient evidence.
If a family member plans to contribute funds toward your acquisition, document the gift and transfer well before closing.
5. Home Equity or Personal Loans With Outside Repayment Sources
Borrowed funds may qualify in certain circumstances, provided the buyer can repay the debt using income that does not come from the business being acquired.
For example, a home equity line of credit (HELOC) may be acceptable if the buyer has another reliable source of income to cover the payments.
Potential outside repayment sources include:
- A spouse's W-2 income
- Rental income
- Investment income
However, income you expect to receive from operating the acquired business cannot be used as the outside repayment source.
The lender must document how the debt will be serviced independently of the acquisition.
6. Prepaid Expenses and Non-Cash Contributions
Certain acquisition expenses you've already paid personally may count toward the required equity injection.
Contributed equipment or inventory may also qualify when supported by an acceptable valuation.
Your lender will need to verify the expenses or assets and determine whether they meet the applicable requirements.
Equity Sources That Can Create Problems
Not all available funds will qualify toward an SBA equity injection.
Borrowed funds repaid through the acquired business. If you need distributions from the business to make payments on a HELOC or personal loan, those funds generally won't qualify as equity. The lender will treat the obligation as debt and account for it when calculating debt service coverage.
Transfers without supporting documentation. Money received from a family member without a gift letter and transfer records may be excluded. The same applies to distributions from another business you own if you cannot document the source.
Large, unexplained deposits shortly before closing. If a significant deposit appears in your account without documentation showing its origin, the lender may exclude it from your qualifying equity injection.
Even when the funds are legitimate, failing to document them properly can leave you short of the required amount.
How Seller Notes Can Count Toward Your Equity Injection
A seller note can sometimes help buyers satisfy part of the required equity injection.
However, the standby terms are important.
Under the 2025 SBA guidelines, a seller note must be on full standby for the entire SBA loan term to count toward the equity injection.
That means the seller receives no principal or interest payments during the life of the SBA loan, which is typically 10 years.
The arrangement must be documented using SBA Form 155 or an equivalent standby agreement.
A qualifying seller note can cover up to 50% of the required equity injection.
Using the earlier example:
| Equity Injection Source | Amount |
|---|---|
| Total required equity injection | $213,500 |
| Seller note on full standby (50%) | $106,750 |
| Required buyer cash contribution | $106,750 |
In this case, the buyer could satisfy half of the equity injection through a qualifying full-standby seller note.
A seller note that pays interest during the SBA loan term, or begins principal payments after a two-year standby period, does not qualify toward the equity injection.
It may still be included in the acquisition financing structure, but it is treated as debt rather than equity.
This is worth discussing with the seller early in negotiations.
A full-standby note requires the seller to wait approximately 10 years before receiving payments, which is very different from a traditional seller-financing arrangement.
Our deal structuring guide covers how to approach these negotiations.
SBA Updates Buyers Should Know About in 2026
There have been additional SBA eligibility and lending guideline changes since the original June 2025 SOP took effect.
Ownership Eligibility Changes Effective March 1, 2026
The SBA introduced stricter ownership eligibility requirements.
Applicants must now be 100% owned by U.S. citizens or U.S. nationals. Lawful permanent residents are no longer eligible to hold ownership in an SBA 7(a) applicant.
While this change does not affect the equity injection calculation, it does limit which buyers can qualify for SBA financing.
For acquisitions that don't meet SBA eligibility requirements, our FLEX program offers financing up to $10 million without the same SBA eligibility restrictions.
SOP 50 10 8.1 Effective October 1, 2026
SOP 50 10 8.1 introduces additional changes for loans receiving an SBA number on or after October 1, 2026.
The minimum equity injection remains 10%, but several requirements have been updated:
- Lender-commissioned quality of earnings reports and valuation costs can count toward the equity injection.
- Certain sources, including investor equity and standby seller debt, are limited to an aggregate maximum of 50% of the required injection.
- The seasoning requirement for refinancing a seller note increases from 24 to 36 months of current payment history.
If you're preparing an acquisition that will be processed under the updated SOP, make sure your proposed financing structure meets the new requirements.
Our complete SBA 7(a) acquisition guide provides additional details.
How to Prepare Your Equity Injection Before Starting a Search
Ideally, buyers should begin organizing their equity injection funds about six months before they expect to pursue an acquisition.
Here are a few steps worth taking early:
Organize your cash. Keep the funds you plan to use in one or two accounts and avoid unnecessary transfers. If consolidation is needed, complete it early and retain the records.
Liquidate investments in advance. If you plan to use brokerage funds, sell the necessary investments early and maintain documentation showing the proceeds.
Document gifts when they're received. If a family member is contributing to your acquisition, complete the gift letter and retain records of the transfer rather than waiting until closing.
Start the ROBS process early. If you're using retirement funds, work with an experienced provider to establish the arrangement and prepare the necessary documentation.
Prepare your home equity financing. If you're using a HELOC, establish the credit line and identify the outside income that will cover the payments.
Taking these steps early can help prevent delays when your lender begins verifying the funds.
The Bottom Line
Meeting the SBA's equity injection requirement involves more than having enough money available.
Your lender needs to verify where the funds came from, confirm that they qualify under SBA guidelines, and review the supporting documentation.
Buyers who prepare those records before submitting an LOI are less likely to encounter last-minute financing problems.
If you're preparing to buy a business and want to confirm whether your funds meet current SBA 7(a) requirements, get prequalified.
