How do you finance an acquisition too big for an SBA loan?

Where the ceiling actually is

SBA 7(a) loans go up to $5 million, and SBA's guaranty to any one borrower is capped at $3.75 million. The ceiling applies to the loan, not the purchase price. A deal's total project costs include the price, working capital the buyer needs at closing, and fees; the loan also has to fit inside the business valuation SBA requires. So a purchase can outgrow SBA well before the headline price reaches the cap, once working capital and closing costs are added.

Where the purchase includes real estate the business will occupy, there is a partial escape: the property can be financed with an SBA 504 loan, and since July 2026 the 504 and 7(a) limits are counted separately. SBA 7(a) vs 504 explains the split. The rest of this page is about the business itself: goodwill, equipment and working capital above what one 7(a) can carry.

The four structures side by side

The columns differ most in what they ask of the buyer and the seller. With SBA in the deal the rules are fixed and known in advance. Without it, everything is negotiated, which is both the risk and the opportunity.

A conventional bank cash-flow loan

For a business with steady earnings and a buyer who can bring real equity, a bank term loan is usually the cheapest money above the SBA cap. Banks size it two ways and lend the lower answer: conventional bank lenders commonly look for debt service coverage of at least 1.25x, and senior cash-flow lenders to lower-middle-market companies commonly lend 2x to 3.5x EBITDA. For a business earning 3,000 of EBITDA, that multiple range alone is 6,000 to 10,500 of debt before coverage is tested; where the loan lands depends on how stable the earnings are, customer concentration, capital spending and the buyer's record.

Equity. There is no rule like SBA's minimum. The equity is whatever fills the gap between the price and the debt, and banks usually want it to be meaningful and at risk before theirs. A buyer who could close an SBA deal with a small check can find the bank asking for much more.

Seller note. Banks welcome a seller note because it defers part of the price and keeps the seller invested. They require it to be subordinated but usually let it pay on schedule while the company is in compliance and not in default. Some banks treat part of a long, subordinated seller note as equity-like in their own analysis; none is bound to. Seller note terms in conventional deals covers what gets negotiated, and the SBA exit rules, including the ban on earnouts, do not apply.

Unitranche from a private credit fund

Unitranche puts senior and subordinated risk into one loan at one blended rate. It stretches further than a bank will, usually with lighter amortization and call protection in the early years. It suits buyers who need more debt than a bank will give and value one lender and one set of documents over the lowest rate. Senior vs unitranche compares the two in detail, and private credit pricing explains what the blended rate is made of.

Equity. Funds lend further on the earnings, but they still want a buyer with money at risk, and those that lend mainly to private equity sponsors expect a sponsor-sized check. Buyers without a sponsor need to show where their equity comes from; see acquisition financing without a sponsor.

Seller note. Because the unitranche already reaches deep into the capital structure, a fund often limits how large the seller note can be and how much it can pay, so that cash is not leaking to the seller from a company already carrying a lot of debt.

A senior loan with mezzanine behind it

The alternative to one stretched loan is two: a cheaper senior loan sized conservatively, and a mezzanine loan behind it that is paid partly in cash, partly in PIK interest, often with warrants. The lenders sign an intercreditor agreement that sets who gets paid and who can act when.

Equity. The mezzanine lender is itself taking near-equity risk, so it wants real equity beneath it; it does not replace the buyer's check. From the senior lender's side, mezzanine counts as debt for total leverage but behaves like a cushion, because it is paid after the senior loan.

Seller note. Now third in line. The seller note ranks behind both lenders and signs a subordination agreement with each, and its payments are the first to stop when things tighten. Sellers should understand that their note is the most junior debt in the deal. Stretch senior vs senior plus mezzanine compares the total cost of the two layered approaches.

Keeping SBA in the deal with a companion lender

A 7(a) loan can sit beside a conventional companion loan, with the two lenders sharing the collateral on terms the SBA lender must accept under SBA's rules. The appeal is the 7(a)'s term of up to 10 years on goodwill and its capped rate on the first $5 million. The catch is that SBA looks at the whole project, not just its share, so SBA's rules govern the entire deal:

• Equity of at least 10% of total project costs, measured against the whole purchase, not just the 7(a).
• A seller note counts for up to half of that equity only on full standby, with no principal or interest paid, for the life of the SBA loan. A note that pays is debt and goes into debt service.
• No earnout to the seller, and in a complete change of ownership a seller who leaves: consulting is limited to 12 months, or up to 24 months under SOP 50 10 8.1 from 1 October 2026.
• An independent business valuation, with the loan for the purchase no larger than it.
• From 1 October 2026, financial due diligence on every change of ownership and a quality of earnings report on acquisitions of $3 million or more excluding real estate, which will catch most deals of this size, and coverage of 1.25x on historical results.
• Personal guarantees from every owner of 20% or more.

Coverage is tested on both loans' payments together. The companion loan often amortizes faster than the 7(a), which can make total debt service heavier than the headline rate suggests. Acquisitions above the SBA limit covers the SBA side of pairing in more depth.

Choosing between them

The right structure is the one that closes on terms the business can live with. The questions that decide it:

• How much equity can the buyer bring? A small check points toward SBA with a companion loan. A large one opens the conventional options.
• What does the seller want? A seller who wants paid on a note over time will resist SBA's full standby. One who wants an earnout rules SBA out.
• Will the buyer sign a personal guarantee? SBA requires one from every 20% owner. Some funds lend without one.
• Is there another acquisition coming? A delayed-draw term loan from a bank or fund can pre-fund add-ons; a 7(a) cannot grow past its cap. See add-on acquisition financing.
• How long is the hold? Call protection on a fund loan costs money if the business is sold or refinanced early. SBA's prepayment fee applies only to 7(a) loans of 15 years or more, which in an acquisition usually means one that includes real estate.

These are best answered by pricing the structures against each other on the same numbers. Transparent's book holds 1,148 lenders that write term and private credit and 278 that write SBA 7(a) and 504, and once the documents are in, Transparent builds the full lender package, including a financing model that runs each structure, in a day. What goes in the package shows what lenders receive.
