The short answer: A HELOC (home equity line of credit) is an acceptable SBA equity-injection source under SOP 50 10 8, but only if you can show the HELOC payment is serviced by income outside the business you're buying (W-2 salary, a spouse's income, or investment income). The injection can never be a loan the acquired business repays. It works, and it can fund the whole 10%, but your home is the collateral, and you're adding a second, usually variable-rate payment.
The one rule that matters
Home equity is one of the more accessible funding sources, if you've owned for a while, you may have far more available than you have in cash. And the SBA explicitly allows it. The catch is a single, non-negotiable condition:
The outside-income rule
Borrowed funds count as equity injection only if the payment is covered by income that doesn't come from the business you're buying. Salary, a spouse's wages, rental income, or investment income must be enough to service the HELOC. The business itself can't be on the hook for it.
The logic mirrors the whole SBA equity-injection philosophy: your down payment must be genuine equity, not a second loan the business quietly repays. If the acquired business had to cover both the SBA loan and the HELOC, the deal would be 100% financed, exactly what the injection rule prevents. Lenders verify the HELOC funds with recent statements and confirm your outside income can carry the payment.
Home equity can be your down payment, as long as your paycheck, not the business, makes the payment.
Worked example: HELOC-funded injection
A $1,000,000 business. You draw $100,000 from a HELOC to fund the full 10% injection, and you have a W-2 salary (or spouse's income) that comfortably covers the HELOC payment:
| Source | Amount | % of price | Serviced by |
|---|---|---|---|
| SBA 7(a) bank loan | $900,000 | 90% | The business's cash flow |
| HELOC on your home | $100,000 | 10% | Your outside W-2 / spouse income |
| Total | $1,000,000 | 100% | Home is collateral for the HELOC |
No new cash from savings, but two things are now true: your home secures the HELOC, and you have a monthly HELOC payment on top of your life. Make sure the outside income that covers it is stable. Model the SBA side with the SBA loan calculator and the price ceiling with the max purchase price calculator.
The risk you can't ignore
Your house is on the line
A HELOC secures the loan against your primary residence. If the business struggles and your outside income also drops, you could face losing both. HELOC rates are typically variable, so the payment can climb. Use home equity only when your outside income is secure and you'd sleep fine with your house as collateral.
HELOC vs the other equity sources
Home equity is one of several ways to fill the injection layer. Quick comparison:
- HELOC, keeps your retirement intact, but risks your home and adds a variable payment.
- ROBS, no monthly payment, but puts retirement savings into the business.
- Seller note, the seller carries part; a full-standby slice can cover up to half the injection.
- Investor equity, no debt on you, but you give up ownership.
Many buyers combine them, a HELOC for part of the injection and a standby seller note for the rest, to avoid maxing any single source.

Frequently asked questions
Yes, a HELOC is an acceptable equity-injection source under SOP 50 10 8, but only if the HELOC payment is serviced by income outside the business being purchased, such as your W-2 salary, a spouse's income, or investment income. The acquired business can't service it.
Because the equity injection can't itself be a loan repaid by the business you're buying. If the business covered both the SBA loan and the HELOC, the deal would be 100% financed. Outside income servicing the HELOC keeps the injection genuine equity.
Your home is the collateral, so a HELOC ties your residence to the business. If the business struggles and outside income drops, you risk both. HELOC rates are usually variable, so payments can rise, and you add a second monthly obligation.
A HELOC is borrowed money serviced by outside income and secured by your home; ROBS uses retirement funds as equity with no payment. A HELOC keeps retirement intact but risks your house; ROBS avoids a payment but concentrates your nest egg. It depends which asset you can better afford to risk.
