Business Acquisition Down Payment Sources

Most first-time buyers assume they need a pile of cash saved up before they can acquire a business. That single misconception kills more deals than anything else we see.

Here is the reality: SBA 7(a) financing requires a 10% equity injection. On a $1M deal, that is $100K. And that $100K does not have to come from your savings account. There are five legitimate business acquisition down payment sources that lenders accept, and knowing all of them can mean the difference between closing a deal this year and sitting on the sidelines for another three.

What Counts as an Equity Injection for SBA Deals

An equity injection is the buyer’s contribution toward the total acquisition cost. Not necessarily cash in hand. Documented value that reduces the lender’s exposure.

The SBA requires a minimum 10% equity injection on business acquisitions. That is the floor, not the target. Some lenders push buyers to 15% or even 20% depending on deal structure, business type, or borrower risk profile. Your injection covers your share of the purchase price plus any associated closing costs not rolled into the loan. On a $1.2M acquisition with $30K in closing costs, you are looking at injecting somewhere around $123K minimum. The lender will want documentation for every dollar of that amount, which is where most buyers underestimate the process.

Cash: Straightforward, But Not the Only Option

Cash is the most obvious business acquisition down payment source. It comes from a personal checking or savings account, gets wired at close, and requires bank statements showing the funds were there for a meaningful period.

Most SBA lenders want 60 to 90 days of bank statements to confirm the cash is “seasoned.” This prevents buyers from borrowing the down payment right before closing, which the SBA explicitly prohibits.

If your cash has been sitting in an account for two or three months, you are fine. If you moved $150K into your checking account last week, expect questions.

One thing buyers miss: the SBA considers the source of your cash. Funds received as a bonus, from selling real estate, or from a business distribution are all acceptable. Borrowed funds are not, with narrow exceptions.

401(k) or IRA Rollover (ROBS Structure)

This is the source most buyers do not know about. And it is one of the most powerful tools available for funding an acquisition.

A ROBS structure (Rollover for Business Startups) allows you to use retirement funds to fund a business acquisition without paying early withdrawal penalties or income taxes. Structured correctly, it is entirely legal and IRS-compliant. Here is roughly how it works: a new C-corporation is formed, the corporation sponsors a qualified retirement plan, you roll your existing 401(k) or IRA into that new plan, and the plan purchases stock in the C-corp. The C-corp then uses those funds as the equity injection.

On a $1.5M deal with a 10% injection requirement, a buyer with $150K in a 401(k) can deploy that entire amount tax-free through a ROBS structure. No penalty. No tax hit.

The catch: ROBS structures require a specialized provider and carry annual compliance costs, typically $1,000 to $2,000 per year in administration fees. They also require ongoing IRS compliance. This is not a DIY project. Use a firm that handles ROBS setups regularly (FranFund and Guidant are two that come up often, though we do not endorse any specific provider).

For buyers sitting on $200K to $500K in retirement funds with limited liquid cash, a ROBS is often the mechanism that makes the deal possible.

Home Equity Line of Credit (HELOC)

A HELOC against your primary residence is one of the more commonly used down payment sources for business acquisitions, and the SBA accepts it.

But wait. Didn’t we just say borrowed funds are prohibited?

There is an important distinction here. The SBA restricts borrowing the down payment in ways that create additional debt service on the acquired business. A HELOC is a personal obligation, not a business debt, and it does not run through the business’s cash flow. That makes it acceptable in most cases.

That said, lenders will look at your total personal debt service when underwriting your eligibility. A large HELOC draw shows up in your personal financial statements and factors into whether the lender believes you can service the SBA loan on top of your existing obligations. So if you have $300K in home equity and can draw $150K at a reasonable rate, this is a clean way to fund your injection. Just run the math on your personal cash flow before assuming you can handle both the HELOC payment and the income you need to extract from the business.

Gift Funds and Family Capital

Gift funds are acceptable as equity injection under SBA guidelines, with one firm requirement: the money must be documented as a gift, not a loan.

That means a signed gift letter from the donor stating the funds are a gift with no expectation of repayment, no equity stake, and no repayment obligation of any kind. The lender will want this in writing.

If your family or investors expect to be repaid, or if any side agreement exists about future compensation or ownership, that changes the nature of the funds entirely. Misrepresenting a loan as a gift to satisfy SBA requirements is fraud. Do not do it.

Legitimate gifts work well when a family member genuinely wants to support your acquisition with no strings attached. Many first-time buyers receive $50K to $100K in gift funds from family to supplement their own cash. The donor will also typically need to provide bank statements showing the gift funds were actually theirs to give.

Seller Notes as Equity Injection (With Conditions)

This is the most nuanced source on the list.

A seller note is a portion of the purchase price that the seller carries back as debt. On a $1.2M deal, a seller might carry $120K as a note, which the buyer repays over time rather than at closing. In some cases, the SBA will allow a seller note to count as part of the equity injection, but only if it is structured as a full standby note. Full standby means the seller receives no principal or interest payments for the full term of the SBA loan. That is typically 10 years. Zero interest. Zero payments. For the duration.

And that is exactly the structure we target.

On the deals we run, we go after a 10-year full standby seller note at 0% interest. We achieve that structure on more than 90% of our deals. When structured this way, the seller note can satisfy part or all of the equity injection requirement depending on lender preferences.

Not every lender accepts seller notes as equity. Some require the full 10% to come from buyer-controlled sources (cash, ROBS, HELOC). This is a conversation to have with your lender early, before you build your deal structure around a seller note injection.

All of That Covers the Individual Sources. The Real Question Is How They Fit Together.

In practice, most buyers fund their equity injection from more than one source.

Say you are buying a $1.8M landscaping services company. Your 10% injection is $180K. You might structure it like this:

$80K from personal savings (seasoned cash)
$60K from a HELOC draw
$40K from a seller note in full standby

Perfectly legitimate combination. The lender will document each source, verify the funds, and confirm the total meets the injection requirement.

The key is getting alignment from your lender on what they will accept before you commit to a deal structure. We work through this with every client during the early deal screening phase so there are no surprises at the underwriting table.

Stacking sources also lets buyers preserve more liquid cash post-close. That matters more than most people realize. You want operating capital available after acquisition. Injecting every dollar of liquidity you have and walking into a business with no cushion is a fast way to create a cash flow crisis in month three. We see this pattern enough to be blunt about it: keep at least 2 to 6 months of working capital in reserve. Non-negotiable.

How Lenders Verify Your Business Acquisition Down Payment Sources

Every dollar of your equity injection will be sourced and documented. Not optional. Core part of SBA underwriting.

Expect to provide:

3 months of bank statements for cash accounts
401(k) or IRA statements for ROBS structures
HELOC documentation and recent mortgage statement
Signed gift letter and donor bank statements for gift funds
Seller note agreement for standby notes

Lenders look for three things: the funds exist, the buyer has legitimate access to them, and no undisclosed debt was incurred to assemble the injection.

Trying to hide where money came from will derail your loan approval. Source your injection cleanly, document it early, and work with your advisory team to get everything organized before you submit an LOI.

Frequently Asked Questions

Can I borrow money from a friend to cover my SBA down payment?

Generally, no. The SBA prohibits using borrowed funds as the equity injection because it creates additional debt service. An exception exists for loans that are fully subordinated with no repayment terms during the SBA loan period, but most lenders will not accept this structure. Gift funds from a friend or family member are acceptable if properly documented as a true gift with no repayment expectation.

How much of the down payment can come from a 401(k) rollover?

The full equity injection can come from a ROBS structure if set up correctly. There is no SBA rule limiting how much of your injection can be retirement funds. The main constraints are the size of your retirement account and the annual compliance costs of maintaining the ROBS. You will generally want at least $50K in retirement funds to make the setup costs worthwhile.

Does the seller note always need to be at 0% interest to count as equity?

Not always, but a 0% full standby note is the cleanest structure and the one most lenders accept without pushback. A seller note with even modest interest payments creates debt service, which weakens the DSCR model and may disqualify it from counting toward the equity injection. We target 0% on full standby because it benefits the deal structure in multiple ways, not just for injection purposes.

What is the minimum down payment for an SBA 7(a) business acquisition loan?

The SBA requires a minimum 10% equity injection for business acquisitions under the 7(a) program. On a $500K deal, that is $50K. On a $2M deal, that is $200K. Some lenders require more depending on the borrower profile and deal characteristics, but 10% is the regulatory floor as defined by SBA guidelines.

Can my equity injection cover closing costs as well as the purchase price?

Yes. The equity injection is calculated against the total project cost, which includes both the purchase price and eligible closing costs. If your total acquisition cost is $1.1M including $100K in closing costs, your 10% injection is $110K. Not all closing costs are included in the SBA project cost calculation, so work with your lender to get the exact injection figure early in the process.

Start Your Acquisition with the Right Capital Stack

Getting the equity injection right is foundational. Structure it wrong and the lender kills it at underwriting. Structure it well and you close a profitable business with as little as 10% down while keeping your personal liquidity intact.

Regalis Capital works with buyers from initial deal screening through close. We help you identify the right down payment sources for your situation, build a deal structure the lender will approve, and manage the entire SBA process on your behalf.
