Business Acquisition Financing: How to Fund the Purchase of an Existing Business in 2026

Starting a business from scratch is a leap into the unknown — no customers, no revenue, no proof the concept works. Buying an existing business sidesteps much of that risk. You acquire a company with a track record, established customers, operating systems, and cash flow from day one. But acquiring an existing business requires capital, often a significant amount, and the way you finance that purchase shapes everything about the deal — your upfront cost, your ongoing obligations, and how much of the business you actually own. At ASAP Capital Solutions, Ashley and Damon Boswell guide owners through acquisition financing regularly, and the structure of the deal matters as much as the price.

In this guide, Ashley and Damon Boswell break down the four primary ways to finance the purchase of an existing business, what each requires, and how to choose the right combination for your situation.

Why Buy an Existing Business?

The appeal of acquisition is grounded in risk reduction. An existing business comes with proven revenue, an established customer base, trained employees, and operational systems that a startup must build from zero. Ashley Boswell frames it simply: when you buy an existing business, you are buying a track record. The financials are real, the cash flow is verifiable, and the market has already validated the product or service. That proof is what makes acquisition financing more accessible than startup financing in many cases — lenders are far more comfortable funding a business with demonstrated revenue than a concept on a pitch deck.

Damon Boswell adds that acquisition is also faster. Instead of spending years building to profitability, the buyer steps into a business that is already generating cash. The trade-off is upfront cost — you are paying for that established value — but for many owners, paying for proven revenue is far less risky than spending years and capital chasing unproven revenue. The question is not whether to buy, but how to fund the purchase intelligently.

Option 1: Business Acquisition Loans (SBA and Conventional)

The most common path to financing an acquisition is a business acquisition loan, available through the Small Business Administration, credit unions, banks, and online lenders. As the U.S. Chamber of Commerce explains, these organizations may offer competitive interest rates for term loans, with SBA loans representing the best shot at a bank loan for an acquisition — though the SBA requires you to explore other options first. Biz2Credit confirms that business acquisition financing in 2026 includes SBA loans, seller financing, term loans, and credit options.

Ashley and Damon Boswell explain that the SBA 7(a) loan is the most widely used program for acquisitions. The SBA itself notes that 7(a) loans are the most common and can be used to assist in the acquisition, operation, or expansion of an existing business. The advantage is a government guarantee that reduces lender risk and enables longer terms and lower down payments than conventional loans. Damon Boswell adds the critical requirement: NerdWallet notes that buyers must put down a 20% to 25% down payment on acquisition loans. That down payment is non-negotiable for most lenders, so the buyer must have meaningful skin in the game before approaching a lender. Conventional, SBA, and online lenders typically require financial documents for the existing company, including cash flow, operating expenses, and physical assets, plus the buyer's personal assets, tax returns, and credit information.

Option 2: Seller Financing

Seller financing is exactly what it sounds like — the current owner finances part of the purchase price directly, allowing the buyer to pay over time rather than upfront. The U.S. Chamber of Commerce identifies this as one of the four primary ways to finance a business purchase, and Biz2Credit includes it among the standard 2026 acquisition financing options. In a seller-financed deal, the seller effectively becomes the lender, holding a note for a portion of the sale price that the buyer repays over an agreed term, often with the business itself as collateral.

Ashley Boswell describes seller financing as one of the most powerful and underused tools in acquisition. It signals that the seller has confidence in the business's ongoing viability — they are willing to be paid from the business's future cash flow rather than demanding all cash upfront. It also reduces the amount the buyer needs from a traditional lender, which can make the difference between a deal that closes and one that stalls. Damon Boswell adds that seller financing is often combined with an SBA loan: the buyer puts down a portion in cash, the SBA finances a portion, and the seller finances the remainder. This layered structure is one of the most common ways acquisitions actually get funded, because it distributes risk and reduces the cash the buyer must bring to the table.

Option 3: Personal Funds and Retirement Assets

For buyers who have accumulated savings or retirement assets, personal funds can play a significant role in financing an acquisition. The U.S. Chamber of Commerce notes that if you have been saving money or have a 401(k), you may use your savings to purchase an established business or as a down payment for other financing options. LendingTree adds that entrepreneurs can use a ROBS — rollovers as business startups — arrangement to open a new business or purchase an existing one, including franchise locations, by rolling retirement funds into the business without early withdrawal penalties.

Damon Boswell is careful to distinguish between the three ways to access retirement funds: withdrawing outright, which triggers taxes and penalties; taking a loan against the 401(k), which must be repaid; and a ROBS, which transfers the balance into the business as equity. Ashley Boswell stresses that a ROBS is a complex structure that requires specialized providers and ongoing compliance, and it should never be undertaken without professional guidance. But for buyers with substantial retirement assets and a strong conviction in the acquisition, it can provide a meaningful source of capital without debt. Personal funds, whether from savings or retirement, are also valuable because they reduce the amount the buyer must borrow — and the more cash the buyer brings, the more favorable the terms from any lender.

Option 4: Private Equity and Investor Capital

For larger acquisitions, private equity or venture capital can provide the capital to close the deal. The U.S. Chamber of Commerce explains that unlike most small business loans, investors do not require you to pay back the money — instead, the SBA notes that venture capital is normally offered in exchange for an ownership share and active role in the company. Investors may also want a say in future business acquisitions and strategic decisions.

Ashley and Damon Boswell are candid about the trade-off. Investor capital is not debt — there is no repayment schedule and no interest — but it costs equity, which is often far more expensive in the long run. Damon Boswell's guidance is to reserve investor capital for acquisitions where the growth potential justifies giving up a share of the upside, and where the buyer's own resources and debt capacity are insufficient to fund the purchase. Ashley Boswell adds that for most small and mid-sized acquisitions, the combination of an SBA loan, seller financing, and personal funds is a more ownership-preserving structure than bringing in equity investors. The decision to take on investors should be deliberate, not a default.

Structuring the Deal: Combining Methods

The U.S. Chamber of Commerce makes an important point that Ashley and Damon Boswell reinforce constantly: depending on the asking price, you may combine two or more funding methods when buying a business. In practice, most acquisitions are not funded by a single source. A typical structure might involve a 20% down payment from the buyer's personal funds, a 50% SBA 7(a) loan, and a 30% seller-financed note. Each layer serves a purpose — the buyer's cash demonstrates commitment, the SBA loan provides the bulk at a competitive rate, and the seller financing bridges the gap while aligning the seller's interests with the business's ongoing success.

Damon Boswell's structuring advice is to think of the deal as a stack, where each layer has its own cost, term, and risk profile. The cheapest capital — typically personal funds and seller financing — should cover as much as possible, with institutional debt filling the remainder. Ashley Boswell adds that the structure must be sustainable against the acquired business's cash flow: the total debt service across all layers must be comfortably covered by the business's operating revenue, or the acquisition will strain the very business the buyer just purchased. Lenders will scrutinize this debt-service coverage closely, and so should the buyer.

What Lenders Review in an Acquisition

Acquisition financing demands documentation from both the business being purchased and the buyer. The U.S. Chamber of Commerce notes that conventional, SBA, and online lenders typically instruct buyers to submit financial documents for the existing company, including cash flow, operating expenses, and physical assets, along with the buyer's personal assets, federal income tax returns, and personal credit information. Biz2Credit confirms that 2026 acquisition financing requires a thorough review of the target company's financials.

Ashley Boswell's preparation checklist for acquisition buyers is comprehensive: obtain three years of the target business's tax returns and financial statements, review their bank statements to verify the revenue is real and consistent, understand their customer concentration and any contracts that may transfer or terminate on sale, and assess the value of physical assets that can serve as collateral. Damon Boswell adds that the buyer's own profile matters as much as the business's — lenders want to see strong personal credit, relevant industry experience, and a clear plan for operating and growing the acquired business. A buyer with no experience in the target's industry will face far more scrutiny than one who knows the business model.

The Down Payment Reality

The down payment is the single most important number in acquisition financing, and Ashley and Damon Boswell set expectations clearly. NerdWallet notes that buyers must put down 20% to 25% on acquisition loans — meaning a $500,000 acquisition requires $100,000 to $125,000 in cash from the buyer before any lender will finance the remainder. That is a meaningful barrier, and it is why the combination of personal funds, seller financing, and sometimes retirement assets is so common.

Damon Boswell's guidance is to determine your available cash first, then size the acquisition to fit. A buyer with $75,000 in liquid funds should be looking at acquisitions in the $300,000 to $375,000 range, not $1 million deals that require a down payment they cannot make. Ashley Boswell adds that seller financing can effectively reduce the required down payment, because the seller-financed portion does not always require the same 20% to 25% equity contribution that an SBA or conventional loan demands. Structuring the deal to minimize the institutional debt — and thus the required down payment — is one of the most effective ways to make an acquisition feasible.

Is Acquisition Financing Right for You?

Damon Boswell's readiness test for acquisition buyers is direct: Do you have 20% to 25% of the target purchase price available in cash or accessible retirement assets? Does the target business have three years of verifiable, consistent revenue and clean financials? Is the business's cash flow sufficient to cover the debt service of the acquisition loan plus your operating costs? Do you have relevant industry experience that gives a lender confidence in your ability to run the business? And have you explored combining an SBA loan with seller financing to reduce your upfront cash requirement? If you can answer yes to these, acquisition financing is a realistic path. If the down payment or the business's financials are weak, those are the gaps to close before pursuing a purchase.
