Business Acquisition Loan in 2026: Types, Terms, and How to Get One

Quick Answer

A business acquisition loan is debt used to buy an existing business. The main types are: an SBA 7(a) loan (the workhorse for deals under about $5 million, financing up to roughly 90% of the project cost with a typical 10% buyer equity injection, part of which can sometimes be a seller note on full standby); a conventional bank acquisition loan (for stronger borrowers or larger deals, usually requiring 20-30%+ down); seller financing (a promissory note from the seller for 10-25%+ of the price); mezzanine or junior debt (for larger deals, filling the gap between senior debt and equity); and combinations (a typical small-business acquisition might stack SBA debt + a standby seller note + buyer equity). Lenders underwrite the business’s cash flow first, the deal has to throw off enough free cash flow to cover all debt service with cushion (a debt-service-coverage ratio comfortably above 1.0x, often 1.25x+) plus a reasonable owner salary. Rates in 2026 vary with prime/SOFR but SBA 7(a) acquisition loans typically price at prime plus a spread; conventional acquisition loans depend on the borrower’s credit and the deal.

A business acquisition loan is what makes most small-business and lower-middle-market acquisitions possible, and getting it right is as much about the deal as about your credit. Lenders underwrite the target business’s cash flow, the structure (asset vs stock), the buyer’s relevant experience, and the price, before they care about your personal balance sheet. This page covers the loan types, typical terms, what lenders look for, and how the financing stacks together.

What this guide covers

SBA 7(a): the workhorse for deals under ~$5M, finances up to ~90% of project cost, typical 10% buyer equity (part can be a standby seller note)
Conventional bank acquisition loan: for stronger borrowers / larger deals, usually 20-30%+ down
Seller financing: a promissory note from the seller for 10-25%+ of the price, shrinks the buyer’s cash need and signals the seller’s confidence
Mezzanine / junior debt: for larger deals, fills the gap between senior debt and equity
The constraint: the business’s free cash flow must cover all debt service with cushion (DSCR comfortably above 1.0x, often 1.25x+) plus a reasonable owner salary
Lenders underwrite the deal, not just you, the target’s cash flow, the structure, your relevant experience, and the price all matter

The types of business acquisition loan

Type	Best for	Typical down payment	Typical terms
SBA 7(a)	Deals under ~$5M; first-time buyers; goodwill-heavy businesses	~10% buyer equity (part can be a seller note on full standby)	10-year amortization (longer if real estate is included); variable rate, often prime + a spread; SBA guaranty fee; personal guaranty required
SBA 504	Acquisitions where significant real estate or heavy equipment is part of the deal	~10% (sometimes 15-20%)	Two loans (bank + CDC); long fixed-rate term on the CDC portion; for real estate/equipment, not pure goodwill
Conventional bank acquisition loan	Stronger borrowers; larger or established businesses; deals above SBA limits	~20-30%+ buyer equity	5-7 year amortization typical; rate based on borrower credit and deal; covenants; personal guaranty common
Seller financing (seller note)	Almost every deal, as part of the stack	n/a, it reduces the cash needed	3-7 year amortization typical; interest at a negotiated rate; secured by business assets or stock; can be on standby to satisfy SBA equity-injection rules
Mezzanine / junior debt	Larger deals ($3M+ EBITDA); filling the gap between senior debt and equity	n/a	Higher rate than senior debt; often includes warrants or a PIK component; subordinated to the senior lender
Unitranche	Lower-middle-market deals; one blended facility instead of separate senior/junior tranches	n/a	Single rate blending senior and junior pricing; one lender; faster to close than a multi-tranche structure
Rollover equity	When the seller keeps a minority stake instead of cashing out fully	n/a, it reduces the cash and debt needed	The seller’s rolled equity becomes part of the new cap table; common in PE-backed deals

How the financing stacks together

Most acquisitions are funded with a mix, not a single instrument. A few common patterns:

Small-business SBA deal: ~80-90% SBA 7(a) loan + ~5-10% standby seller note + ~5-10% buyer equity. The standby seller note can count toward the buyer’s required equity injection.
Conventional small-deal: ~60-70% bank acquisition loan + ~15-25% seller note + ~10-20% buyer equity.
Lower-middle-market PE deal: ~40-60% senior debt + ~10-20% mezzanine/junior debt + ~20-40% equity (some of which may be seller rollover).
Search fund / ETA deal: SBA 7(a) (if under the limit) or conventional senior debt + seller note + searcher/investor equity, often with rollover equity from the seller.

What lenders underwrite (and in what order)

The target’s cash flow. The single biggest factor. The lender wants to see that the business’s free cash flow, after a reasonable salary for the new owner-operator, covers all debt service with cushion. They quantify this with the debt-service-coverage ratio (DSCR): cash flow available for debt service divided by total annual debt payments. They generally want it comfortably above 1.0x, often 1.25x or higher. Layer on too much debt and a normal business hiccup breaks the cushion.
The structure. Asset vs stock sale affects the lender’s collateral position and the buyer’s basis. SBA loans typically prefer (and sometimes require) an asset structure.
The buyer’s relevant experience. SBA lenders in particular want to see that the buyer has management or industry experience relevant to running the business. A first-time buyer with no related background is a harder underwrite.
The price. An over-priced deal (a multiple well above sector norms) is a red flag, the lender doesn’t want to over-collateralize. A business valuation (independent, often required by the SBA above a threshold) supports the price.
The collateral. Business assets, real estate, and the buyer’s personal assets (a personal guaranty is standard on SBA and most conventional acquisition loans; a lien on a primary residence is common if there’s equity).
The buyer’s credit and equity. Personal credit score, the source and seasoning of the equity injection (it can’t be borrowed in most SBA cases, except a standby seller note), and post-close liquidity reserves.

Typical 2026 terms and rates

SBA 7(a) acquisition loans: typically a variable rate at prime plus a spread (the maximum spread is capped by SBA rules and varies with loan size); 10-year amortization for a business-only acquisition (up to 25 years if real estate is included); an SBA guaranty fee (a percentage of the guaranteed portion, scaled to loan size); a personal guaranty from owners of 20%+; and a required ~10% buyer equity injection.
Conventional bank acquisition loans: rate depends on the borrower’s credit, the deal size, and the lender’s risk appetite, generally a premium over comparable real-estate or equipment loans because acquisition lending is riskier; 5-7 year amortization typical; financial covenants; usually a personal guaranty; 20-30%+ down.
Seller notes: negotiated, often in the mid-to-high single digits or low double digits, with 3-7 year amortization; secured; sometimes on standby (no payments) for an SBA-required period.
Mezzanine debt: low-to-mid teens all-in (cash coupon plus PIK plus warrant value), subordinated to senior debt; used on larger deals.

Rates move with prime and SOFR, so confirm current pricing with a lender; the structure (down payment, amortization, standby periods, covenants) is often more negotiable than the headline rate.

How to actually get an acquisition loan

Start with an SBA-preferred lender (PLP) if the deal is under ~$5M. PLP lenders can approve SBA loans in-house, which is faster. Get pre-qualified before you go deep on a target.
Bring relevant experience or a credible operating plan. SBA lenders want to see you can run the business; a first-time buyer should pair with a strong management team or demonstrate transferable experience.
Have your equity injection ready and seasoned. Most SBA cases require the injection to be the buyer’s own funds (or a standby seller note); it can’t be a personal loan in most cases. Document its source.
Get a clean target. Verifiable financials (tax returns matching the P&L), no disqualifying issues, a defensible price. A messy target is hard to finance.
Structure the seller note to help. A properly structured standby seller note can satisfy part of the SBA equity-injection requirement and reduce the buyer’s cash need.
Get an independent business valuation (the SBA requires one above a threshold for acquisitions and changes of ownership; it also protects you from overpaying). See our note on determining a fair acquisition price.
Model the DSCR yourself first. If the deal doesn’t cover debt service with cushion at the proposed price and structure, it’s not financeable, and you should re-trade the price, not layer on more debt.
Use a transactional M&A attorney. The loan, the purchase agreement, the seller note, and the standby agreement all have to fit together.

For finding deals to finance, see how to find businesses for sale and how to source acquisition deals. If you’re an owner reading this because a buyer will be asking for seller financing: seller notes and standby structures are normal, not red flags, and our free valuation tool and broker alternative guide are the place to start on the sell side.

Don’t Overpay (It Kills the Loan)

Make sure the price is financeable

An over-priced deal won’t get financed, the DSCR doesn’t work. If you’re an owner on the other side, knowing the defensible value matters too. Free 90-second sector-adjusted valuation, no email gate, no obligation.

Frequently asked questions

What is a business acquisition loan?

Debt used to buy an existing business. The main types: an SBA 7(a) loan (the workhorse for deals under about $5 million, financing up to roughly 90% of project cost with a typical 10% buyer equity injection); a conventional bank acquisition loan (for stronger borrowers or larger deals, usually 20-30%+ down); seller financing (a promissory note from the seller for 10-25%+ of the price); mezzanine or junior debt (for larger deals); and combinations. Lenders underwrite the target business’s cash flow first, the deal has to cover all debt service with cushion (a debt-service-coverage ratio comfortably above 1.0x, often 1.25x+) plus a reasonable owner salary.

How much down payment do I need for a business acquisition loan?

Typically about 10% of the project cost for an SBA 7(a) acquisition loan (and in many cases part of that 10% can be a seller note on full standby rather than the buyer’s own cash). For a conventional bank acquisition loan, usually 20-30% or more. The down payment (the buyer’s equity injection) generally has to be the buyer’s own funds in SBA cases, not a personal loan, with a documented source, plus the buyer needs working-capital reserves on top. Larger PE-style deals use 20-40% equity, some of which may be seller rollover.

What are business acquisition loan interest rates in 2026?

They vary with prime and SOFR, so confirm current pricing with a lender. SBA 7(a) acquisition loans typically price at prime plus a spread, with the maximum spread capped by SBA rules and scaled to loan size. Conventional bank acquisition loans depend on the borrower’s credit, the deal size, and the lender’s risk appetite, generally a premium over comparable real-estate or equipment loans because acquisition lending is riskier. Seller notes are negotiated (often mid-to-high single digits or low double digits). Mezzanine debt runs low-to-mid teens all-in. The structure is often more negotiable than the headline rate.

Can I get a business acquisition loan with no money down?

Rarely a true zero, but you can sometimes get close. On an SBA 7(a) deal, part of the required ~10% equity injection can be a seller note on full standby (no payments for the loan term) rather than the buyer’s own cash, which is lender- and deal-dependent. Genuine no-money-down deals exist mainly for distressed businesses, very small businesses, or highly motivated sellers who finance nearly all of it. The constraint is always the debt-service-coverage ratio: the business’s free cash flow has to cover all the layered debt with cushion, or the deal isn’t financeable regardless of the down payment.

What do lenders look for in a business acquisition loan?

In rough order: (1) the target’s cash flow, can the business cover all debt service with cushion after a reasonable owner salary (a debt-service-coverage ratio comfortably above 1.0x, often 1.25x+); (2) the deal structure (asset vs stock); (3) the buyer’s relevant management or industry experience; (4) the price (an over-priced deal is a red flag; the SBA requires an independent valuation above a threshold); (5) the collateral (business assets, real estate, and a personal guaranty, often with a lien on the buyer’s home if there’s equity); and (6) the buyer’s credit and the source and seasoning of the equity injection.

How long does it take to get a business acquisition loan?

Roughly 45-90 days from application to funding for an SBA 7(a) acquisition loan with a preferred (PLP) lender, longer with a non-PLP lender or if there are complications. Conventional bank acquisition loans can be faster (30-60 days) for strong borrowers, or slower if there’s heavy underwriting. The timeline runs alongside due diligence and the purchase-agreement negotiation. Getting pre-qualified before you go deep on a target, and having a clean, well-documented deal, compresses the timeline; a messy target or an unprepared buyer stretches it.

What is the debt-service-coverage ratio and why does it matter for an acquisition loan?

The debt-service-coverage ratio (DSCR) is the business’s cash flow available for debt service divided by its total annual debt payments. Lenders use it to test whether the acquired business can actually carry the loan, they generally want it comfortably above 1.0x, often 1.25x or higher, so there’s cushion for a normal business downturn plus a reasonable salary for the new owner. If a deal’s DSCR is too thin at the proposed price and structure, it’s not financeable, and the fix is re-trading the price, not layering on more debt. Model your own DSCR before pursuing a deal.

Should I use seller financing as part of my acquisition loan?

Usually yes, it’s standard. A seller note for 10-25%+ of the price reduces the buyer’s cash need, signals the seller’s confidence in the business (a seller who won’t finance any of it is a yellow flag), aligns the seller with a smooth transition, and, in SBA deals, a properly structured standby seller note can help satisfy the buyer’s required equity injection. Negotiate the rate, term, amortization, and security; the seller should protect themselves with a security interest and acceleration provisions. Most well-structured small-business acquisitions stack SBA or conventional debt with a seller note and buyer equity.
