SBA equity injection sources: what a lender can count

Published October 25, 2026 · Rules checked against SBA and IRS sources as of October 2026

Short answer

SOP 50 10 8.1 splits equity into two kinds. Unlimited sources (your unborrowed cash, gifts, grants with no repayment, verified prepaid project costs, and personal loans repaid from outside the business) can make up the whole injection. Limited sources (standby debt, seller notes on full standby, and minority investors under 20%) can make up no more than half of it. Fees to brokers or advisers never count.

The amount of equity is the easy part: 10% of total project cost on most acquisitions. Whether a given dollar counts is where deals slow down. Here's the rule set in Appendix 15 of SOP 50 10 8.1 and how lenders apply it.

Two buckets

Unlimited and limited equity sources Unlimited: up to 100% Your cash, not borrowedGifts of cashGrants with no repaymentVerified prepaid project costsPersonal loan to a guarantor,repaid from outside the business Limited: at most 50% Seller note on full standbyOther standby debtMinority investor under 20%,no control Combined, these can't exceedhalf of the required injection.
Fees for education, advisory services or a loan agent aren't equity at all.

Unlimited sources in detail

Limited sources in detail

There's a second use for limited sources: when the price exceeds what the valuation and QoE support, extra limited-source funds can bridge it, but they must be on full standby.

Worked example of the half cap

Illustration, not a real deal

Say total project cost is $2,200,000, so the required injection is $220,000. You have $90,000 of cash, the seller will put $100,000 on full standby, and a friend wants to invest $60,000 for 10%.

SourceBucketCounts toward $220,000
Your cashUnlimited$90,000
Seller standby noteLimited$110,000 combined maximum (half of $220,000)
Friend's investmentLimited
Total counted$200,000, $20,000 short

The limited sources total $160,000 but only $110,000 can count. You'd need $20,000 more from an unlimited source (your cash or a gift), or a lower project cost. The extra $50,000 of limited money can still go into the deal; it just doesn't satisfy the minimum.

When the 10% can be lower

Business Expansions and Owner Buyouts can have the requirement reduced or eliminated by the lender if the business has sufficient liquidity and working capital and no negative net worth at the last fiscal year-end. If eliminated, no dedicated permanent working capital can go into a 7(a) term loan for 90 days (de minimis amounts allowed). ESOPs buying 51% or more have no SBA equity requirement. Initial Acquisitions: no reduction. See no-down-payment SBA loans.

Gift funds

Yes. SOP 50 10 8.1 lists cash that isn't borrowed, "whether on the business's balance sheet or from other sources (e.g. gift)," as an unlimited equity source, so a genuine gift can cover your whole 10% injection. It has to be a real gift with no repayment expected; money a relative expects back is a loan, and a loan only counts if it's repaid from a source other than the business.

Family money is one of the most common ways first-time buyers reach the 10%. Done properly, SBA treats it the same as your own savings.

What the lender will want

Common mistakes

Other ways to fund equity: home equity, ROBS and seller standby notes.

Home equity loans

Yes, with a condition. SOP 50 10 8.1 counts cash from a personal loan to a guarantor as an unlimited equity source only when repayment can be shown to come from a source other than the business's cash flow, and your salary from the business doesn't qualify. A home equity loan repaid from a spouse's income, a pension or other investments can work; one you plan to repay from what the business pays you can't.

For many buyers, home equity is the biggest pool of money they have. SBA lets you use it, but tests where repayment will come from.

The test

Does borrowed equity count? How will you repay it? Outside incomespouse, pension, rentals= counts as equity Business salaryor business cash= doesn't count
The lender documents the outside source in the file.

A worked example

Illustration, not a real deal

Say you need $150,000 of equity. You take a $150,000 home equity loan at an assumed 8.5% over 15 years, about $1,477 a month or $17,700 a year. Your spouse earns $95,000 a year from a job unrelated to the business. The lender can count the $150,000 as equity if your household budget shows the $17,700 is covered by your spouse's income after your other obligations. That same payment goes into global cash flow.

Common questions

How do lenders verify my equity?

With bank statements showing the funds are yours and not borrowed (or a gift letter and transfer for gifts), paid invoices or canceled checks for prepaid expenses, and the standby agreement and note for any seller standby debt.

Can an investor's money count as my equity?

Yes, if the investor holds under 20%, has no control, and the investment isn't subject to repayment or distributions (other than for taxes) before the SBA guaranty is released. It's a limited source, so it shares the half cap with standby debt.

Does equity have to be in the business before closing?

The lender must verify it's injected, usually at or before closing. Prepaid expenses, such as a deposit or report fees, count if documented.

Can I use equity in a building I'm contributing?

Contributed assets can be considered in some situations; discuss with the lender. The SOP's listed unlimited sources focus on cash, grants and verified prepaid expenses.

What should a gift letter say?

The donor's name and relationship, the amount, the date, and a clear statement that it's a gift with no expectation of repayment and no ownership stake in return. Your lender may have its own form.
