Understanding Acquisition Financing Options: How I Stack Capital to Buy Businesses

Acquisition financing options are the funding sources a buyer combines into a capital stack to purchase an operating business — typically SBA 7(a) loans, conventional bank debt, seller notes, mezzanine debt, equity partners, and no-money-down structures. Each source has a different cost, a different priority in the stack, and a different set of covenants. The right combination protects your DSCR, keeps you in control, and gets the deal closed. The wrong combination buries you in debt service on day one.

Look, I’ve bought and helped students buy 300+ businesses over 30 years. Almost none of them were funded with a single source. Real deals get done by stacking capital — a chunk from the SBA, a chunk from the seller, sometimes a slice of equity, sometimes a mezz piece to close the gap. Focus on terms over price. Always.

Here’s how each financing option actually works, when to use it, and how we teach students to combine them inside Dealmaker Academy.

Why the Capital Stack Matters More Than Any Single Loan

The capital stack is the order in which the money going into your deal gets paid back. Senior debt sits at the bottom, gets paid first, and costs the least. Mezzanine sits in the middle, costs more, and gets paid after the senior lender is happy. Equity sits at the top, gets paid last, and costs the most because it’s taking the most risk.

You don’t “get financing” for a deal. You build a stack. Every layer changes your monthly debt service, your ownership, and your risk. Get the stack right and a marginal deal becomes bankable. Get it wrong and a great business becomes a losing purchase.

SBA 7(a) Loans: The Workhorse of Small Business Acquisitions

An SBA 7(a) loan is a government-guaranteed loan program that lets qualified buyers finance up to 90% of a business acquisition through an SBA-approved lender, with the U.S. Small Business Administration backing a large portion of the loan to reduce the bank’s risk. It’s the single most common financing source for buyers acquiring an established U.S. business under roughly $5 million in enterprise value.

What you need to know:

• Loan size. SBA 7(a) loans typically go up to $5 million per borrower. That covers the vast majority of Main Street and lower-middle-market deals.
• Term. Business acquisitions usually amortize over 10 years. Real estate blended in can push the term longer. Longer term = lower monthly payment = better DSCR.
• Down payment. Most SBA acquisition loans require 10% equity injection. A portion of that can come from a seller note on standby — meaning the seller doesn’t get paid until the SBA loan matures or is refinanced.
• Personal guarantee. Anyone owning 20%+ of the buyer entity signs a personal guarantee. This is not optional. Know what you’re signing.
• Cash flow test. The lender wants to see the business’s historical cash flow support the new debt with a comfortable DSCR — ideally 1.5x or higher. Cash flow positive with a DSCR ≥1.5x is non-negotiable.

SBA loans are slower to close than a private lender — 60 to 90 days is realistic. Ask about interest rate structures and current pricing with your lender directly. Rates move, and I’m not going to guess for you.

Conventional Bank Debt: When You Don’t Need the SBA

Conventional bank debt is a commercial loan issued directly by a bank without an SBA guarantee, usually reserved for buyers with strong balance sheets, larger deals, or established borrowing relationships. If you already have banking relationships and the target throws off enough cash to service debt without government backing, conventional is faster and often has fewer covenants.

Where conventional fits:

• Deals above $5 million. Once you’re past the SBA 7(a) cap, you’re looking at conventional term loans, asset-based lending, or specialty lenders.
• Strong buyer balance sheets. Banks want to see liquid assets, a track record, and often an existing depository relationship.
• Asset-heavy targets. Manufacturing, transportation, and businesses with real estate collateralize well for conventional lenders.
• Faster close. 30 to 60 days is common versus 60 to 90 for SBA.
• Covenants matter. Read them. Minimum DSCR covenants, restrictions on distributions, personal guarantees — these will govern how you operate for years.

Seller Financing (Seller Notes): The Most Underused Tool in the Stack

Seller financing is a promissory note issued by the buyer to the seller for a portion of the purchase price, repaid over time with agreed terms — effectively the seller acting as your lender for part of the deal. This is the single most powerful lever on Main Street deals. Sellers who want to retire, who trust you, and who like the price often carry paper.

Why I push seller notes on almost every deal:

• You can buy a business like leasing a car. Structured payments over time, out of the cash the business itself generates. Seller notes make that possible.
• Alignment. A seller carrying paper has a real reason to hand over the business cleanly, transition well, and pick up the phone after close.
• Standby structures for SBA deals. A seller note on full standby (no payments for 2+ years) can count toward your SBA equity injection. Read the SBA SOP carefully with your lender before structuring this.
• Interest-free notes work. Yes, they exist. I’ve closed them. Whether the seller agrees depends on tax structuring, price, and rapport. Ask your CPA about imputed interest before you get creative.
• Terms trump rates. Focus on length of amortization, payment schedule, and prepayment rights. Never propose a rate — let the seller anchor and negotiate from there.

Get every seller note in writing. Full promissory note, security agreement if collateralized, personal guarantee scope defined. No verbal promises. Ever.

Mezzanine Debt: The Bridge Between Senior Debt and Equity

Mezzanine debt is a hybrid financing layer that sits between senior secured debt and equity in the capital stack — usually subordinated debt, often with warrants or an equity kicker, priced higher than bank debt because it’s riskier and paid later. Mezz shows up on larger acquisitions when the senior lender won’t stretch further but the buyer wants to preserve equity ownership.

When mezz makes sense:

• Larger deals ($5M+). Below that, seller notes usually fill the same gap more cheaply.
• Filling a gap in the stack. Senior lender caps at 3x EBITDA of debt. Deal needs 4x. Mezz covers the difference.
• Preserving equity. You could sell more equity to close the gap — but mezz lets you keep more of the upside.
• Cash flow flexibility. Some mezz structures allow PIK (payment-in-kind) interest, meaning interest accrues to the balance instead of being paid in cash. Preserves cash for growth.
• Equity kickers. Expect the mezz lender to ask for warrants or a small equity stake as part of the pricing. That’s normal. Negotiate the strike price and dilution carefully.

Mezzanine is not cheap capital. Talk to your CPA and lender about all-in cost before committing.

Equity Partners: When to Bring Someone Into the Cap Table

An equity partner contributes cash toward the down payment or purchase price in exchange for an ownership stake in the acquired business, sharing in future profits, distributions, and eventual exit proceeds. Equity is the most expensive form of capital because it never gets paid off — the partner owns a slice of the business forever until you buy them out or sell.

Where equity partners fit:

• Down payment help. You’ve got the deal, the operator skills, and the SBA-ready credit — but not the full 10% equity injection. An LP-style partner contributes cash for a percentage of the equity.
• Larger deals without SBA. Above the SBA cap, equity is often required to complete the stack alongside conventional debt and mezz.
• Search fund model. Investors back a searcher to find a deal, then fund the acquisition and take significant equity.
• Operator-investor split. Owner-operator vs. owner-investor matters. If you’re the operator, negotiate carried interest or promote for the sweat you’re putting in — don’t just take a straight pro-rata split.
• Governance. Every equity partner comes with rights — voting, board seats, information rights, drag-along. Get every one of them into the operating agreement with a good attorney.

No-Money-Down Deals: Real, But Not the Norm

A no-money-down acquisition is a deal structured so the buyer contributes little or none of their own cash at close, funded entirely through some combination of seller financing, SBA debt using seller-standby notes as the equity injection, earnouts, holdbacks, and assumption of existing debt. They’re absolutely possible. They’re absolutely not the default. And they only work when the deal structure, the seller, and the lender all line up.

How no-money-down deals typically get built:

• Full seller carry. Seller finances 100% of the purchase price over an amortization schedule. Rare, but I’ve seen it — usually with a motivated seller and a trusted buyer.
• SBA + seller standby. SBA finances 90%. Seller carries a 10% note on full standby that qualifies as the equity injection. You bring closing costs only.
• Earnouts. Portion of the purchase price is paid only if the business hits agreed performance targets post-close. Reduces day-one cash need.
• Holdbacks and escrows. Chunks of the purchase price sit in escrow for 12-24 months to cover indemnification claims, then release to the seller. Reduces the cash you need to fund at close.
• Assumed debt. Buyer takes over existing loans on the balance sheet as part of the purchase consideration. Check every loan document for change-of-control clauses.

These structures work. They also require sophisticated negotiation, real rapport with the seller, and a lender who understands what you’re doing. Don’t go in cold.

How to Choose the Right Capital Stack

The right stack for your deal depends on the target, your balance sheet, and the seller’s willingness to carry paper. Here’s the order I work through it:

1. Confirm the business supports the debt. Cash flow positive with DSCR ≥1.5x after all layers of debt service. Non-negotiable. If it doesn’t clear, restructure or walk.
2. Anchor senior debt first. SBA 7(a) for deals under $5M, conventional for larger or asset-heavy deals. This layer is your cheapest capital — max it out within DSCR constraints.
3. Ask the seller to carry paper. Always. Even 10-20% seller financing tightens alignment and reduces what you need from other sources.
4. Fill the gap with mezz or equity. Above $5M and short on the stack? Mezz preserves ownership; equity partners preserve cash flow. Model both.
5. Layer in earnouts, holdbacks, and escrows. These aren’t financing per se, but they change how much cash you actually need at close and shift risk back to the seller.
6. Get a CPA and attorney in the room early. Tax structuring, entity choice, personal guarantee scope, and covenant negotiation all move real money. Don’t cheap out here.

What About Rates and Specific Terms?

I don’t quote rates. Not in a blog post, not in coaching, not ever. Rates move, terms vary by lender, and your credit profile changes what you get offered. Anyone selling you a specific rate on the internet is selling you last month’s news.

What I will tell you: focus on the structure. Amortization length, prepayment terms, personal guarantee scope, covenant tightness, and where each layer sits in the stack matter far more than a fraction of a point on the coupon. Get your lender and CPA on the phone for actual pricing.

Frequently Asked Questions

What are the main acquisition financing options for buying a business?

The main acquisition financing options are SBA 7(a) loans, conventional bank debt, seller financing (seller notes), mezzanine debt, equity partners, and no-money-down structures built by combining seller standby notes, earnouts, holdbacks, and assumed debt. Most real deals combine two or more of these into a capital stack rather than using one source alone.

What is an SBA 7(a) loan used for in business acquisitions?

An SBA 7(a) loan is the most common government-guaranteed loan used to finance small business acquisitions in the United States, typically up to $5 million per borrower. It usually requires a 10% equity injection, amortizes over 10 years for business assets, and requires a personal guarantee from anyone owning 20% or more of the buyer entity. The SBA guarantee reduces the lender’s risk so more deals get funded.

How does seller financing work in an acquisition?

Seller financing is when the seller carries a promissory note for part of the purchase price, so the buyer pays the seller over time from the cash flow of the acquired business. It’s the most flexible and underused tool in the stack. Terms, amortization schedule, prepayment rights, and any standby provisions all get negotiated directly with the seller. Never propose a rate first — let the seller anchor and negotiate the structure.

What is mezzanine debt in an acquisition?

Mezzanine debt is subordinated financing that sits between senior secured debt and equity in the capital stack. It’s typically used on larger acquisitions to bridge the gap when senior lenders won’t stretch further and the buyer wants to preserve equity ownership. Mezz is priced higher than bank debt because it’s riskier and often includes warrants or an equity kicker as part of the total return to the lender.

Can you buy a business with no money down?

Yes, no-money-down business acquisitions are real, but they aren’t the default. They’re built by combining full seller financing, SBA loans with seller standby notes used as the equity injection, earnouts, holdbacks in escrow, and assumed debt already on the balance sheet. They require sophisticated structuring, real rapport with the seller, and a lender who understands the deal. Get a CPA and attorney involved before signing anything.

What is the difference between debt and equity in an acquisition capital stack?

Debt gets paid back on a schedule with interest and eventually goes away, leaving the buyer with full ownership of the acquired business. Equity is cash contributed in exchange for ownership — it never gets “paid back” the same way; the equity partner owns a permanent slice of the business until bought out or sold. Debt is cheaper but adds monthly obligations; equity preserves cash flow but permanently dilutes ownership and future upside.

Why is DSCR important in acquisition financing?

Debt service coverage ratio (DSCR) measures whether the acquired business generates enough cash flow to cover all of its debt payments plus a safety cushion. A DSCR of 1.5 or higher is the minimum threshold for a bankable acquisition — meaning the business generates at least $1.50 of cash flow for every $1.00 of debt service. Below 1.5, the deal is gambling on growth to service the debt. Cash flow positive with DSCR ≥1.5x is non-negotiable.

Where can I learn how to structure real acquisition deals?

Dealmaker Academy teaches the full capital stack — SBA, conventional, seller notes, mezz, and creative structures — on live acquisition targets alongside Carl Allen and the coaching team. The Protégé Community is where active dealmakers share the structures they’re actually closing. Both are built for people originating and closing deals, not just reading about them.
