Business Acquisition Loans: What They Cost, How to Qualify, and How to Choose

A business acquisition loan is financing used to buy an existing business, buy out a partner, or purchase a franchise, repaid over time from the cash flow of the company you acquire. Unlike a startup loan, lenders can underwrite against a real operating history — the target's revenue, profit, and bank deposits — which is why acquisitions are often easier to finance than launching something from scratch. The trade-off is scrutiny: you are asking a lender to bet on a business you do not yet own, so they look closely at the target's books, your experience, and how much of your own money you are putting in. This guide covers the loan types that actually fund acquisitions, what each one costs in real dollars, the down payment and credit bar you should expect, and how to move from "interested" to "funded" without wasting weeks on the wrong lender.

What a Business Acquisition Loan Actually Funds

The term covers several different transactions that all share one feature: you are buying something that already exists rather than building it. Understanding which transaction you are doing changes which lender and loan type fits.

• Buying an existing business outright. The most common case — you purchase a going concern, its assets, and often its customer relationships and staff. Lenders love these because the target has a track record they can underwrite.
• Buying a franchise. Purchasing a new or resale franchise unit. Franchises on the SBA's approved directory can move faster because the brand's economics are already documented.
• Partner or shareholder buyout. Financing to buy out a departing co-owner. This is technically a change-of-ownership deal and is eligible for SBA financing, but the remaining owner usually must personally guarantee the debt.
• Bolt-on or add-on acquisition. An existing business buying a competitor or complementary company to grow. Here you can lean on your own company's financials, which widens your options.

What an acquisition loan is not: it is not a blank check. Proceeds are tied to a specific purchase, documented by a purchase agreement and usually a third-party valuation. If you also need money to renovate, restock, or cover the first few months of payroll after closing, say so up front — that working capital can often be rolled into the same loan.

The Main Financing Options, Compared

There is no single "acquisition loan" product. In practice, buyers use one of four financing sources, often in combination. The right mix depends on deal size, how fast you need to close, your credit, and how much cash you can put down.

A very common structure stacks these: an SBA 7(a) loan for the bulk of the price, a seller note for 10%, and the buyer's own cash for the required equity injection. Revenue-based financing then rarely funds an entire purchase, but it is genuinely useful for the pieces the primary loan will not cover — post-closing inventory, payroll during the transition, or a smaller add-on deal you need to close this week rather than this quarter.

Real Cost Examples: What You Actually Pay

Rates and terms vary by lender, deal, and market conditions, so treat every figure below as a rounded illustration, not a quote. What matters is seeing how the same $500,000 acquisition looks under different financing — the monthly payment and total cost can differ dramatically.

Two things stand out. First, longer terms lower the monthly payment but raise the total interest paid — the SBA example costs more overall than the shorter conventional loan, yet its lighter monthly bite may be exactly what a newly acquired business needs to breathe. Second, revenue-based financing is priced with a factor rate, not an interest rate: a 1.30 factor on $50,000 means you repay $65,000 regardless of how fast you pay it back. That makes it expensive as long-term debt but reasonable as a short bridge. Match the tool to the job.

The Qualification Reality (What Underwriters Really Check)

Marketing pages list a credit score and a revenue minimum and stop there. Real approval turns on more, especially because the lender is underwriting a business you do not yet own. Here is what genuinely moves a decision.

• The target's financials, not just yours. Lenders want two to three years of the seller's tax returns and profit-and-loss statements showing the business earns enough to cover the new loan payment with room to spare — often expressed as a debt-service coverage ratio of about 1.15-1.25 or higher.
• Your equity injection. Expect to put in roughly 10%-20% of the price in cash you cannot borrow against the same deal. A portion can sometimes come from a seller note on standby, but lenders want to see that you have real skin in the game.
• Relevant experience. Buying a restaurant when you have run restaurants is a far easier approval than buying an industry you have never touched. Weak experience can sometimes be offset by keeping the seller or key managers on during a transition.
• A defensible valuation. Conventional and SBA lenders order or require an independent business valuation. They will not finance a price above what the business is independently worth, so an over-priced deal stalls no matter how strong you are.
• Personal guarantee and collateral. Nearly every owner with 20%+ ownership signs a personal guarantee. Lenders also typically take a lien on the acquired business assets, and sometimes on personal real estate for larger loans.

Revenue-based and MCA-marketplace financing flips this emphasis. Approval there leans on your bank-deposit history and monthly revenue far more than your credit score — FICO of 500+ can qualify, minimums start around $10,000, and funding often lands in 24-48 hours. It will rarely underwrite an entire purchase, but it is the realistic option when your credit is thin, when you need the equity-injection cash fast, or when a smaller bolt-on has to close before a slower bank loan could ever fund. It is never guaranteed — approval still depends on your revenue and deposits.

Due Diligence: The Step That Protects Your Loan and Your Money

Due diligence is the homework you do on the target before you close — and it is exactly what lenders lean on, so doing it well helps your financing as much as it protects you. Skipping it is the most expensive mistake a first-time buyer makes.

• Verify the revenue. Reconcile the seller's claimed sales against bank statements, merchant-processing statements, and filed tax returns. Numbers that only appear in a spreadsheet are not numbers.
• Understand why they're selling. Retirement is a good reason. A lost major customer, a new competitor across the street, or a lease about to expire are reasons that change the price.
• Check what transfers. Confirm the lease assigns to you, key contracts survive a change of ownership, licenses transfer, and critical employees intend to stay.
• Separate the deal structure. An asset purchase (you buy the assets, not the legal entity) usually shields you from the seller's past liabilities and is the more common structure; a stock/equity purchase carries the company's history with it. This choice has real tax and liability consequences — involve a CPA and an attorney.
• Model the post-close cash flow. Build a simple projection: revenue, minus real operating costs, minus the new loan payment. If it is tight before you have made a single improvement, renegotiate the price or the terms.

Good due diligence produces exactly the documents a lender wants anyway — verified financials, a clean valuation basis, a transferable lease — so it doubles as loan preparation.

How to Apply, Step by Step

The path from interest to funding is more predictable than most buyers expect. Working roughly in this order keeps you from losing a deal to slow paperwork.

1. Get the target's financials early. Ask for two to three years of tax returns, P&Ls, and recent bank statements before you fall in love with the deal. This determines both the price and your financing options.
2. Sign a letter of intent (LOI). A non-binding LOI sets the price and basic terms and signals to lenders that a real transaction exists.
3. Pre-qualify with the right lender type. If the deal is under ~$5M and the business is profitable, start with SBA 7(a) lenders. If you need speed or your credit is thin, get a parallel quote from a revenue-based marketplace so you know your fast-money backstop.
4. Assemble your package. Personal financial statement, resume showing relevant experience, the target's financials, the purchase agreement, and a simple business plan with post-close projections.
5. Order or cooperate with the valuation and underwriting. This is where deals slow down; respond to document requests within a day, not a week.
6. Close and coordinate funding. Line up your equity injection, any seller note, and working capital so the pieces arrive together at closing.

A practical sequencing tip: run the slow track (SBA or bank) and the fast track (revenue-based) at the same time. If the primary loan comes through, use it for the bulk of the purchase. If it stalls or falls short on working capital, you already have a same-week option in hand instead of starting over.

Common Mistakes That Sink Acquisition Financing

Most declined or collapsed deals fail for a handful of avoidable reasons. Knowing them ahead of time is worth more than any single rate quote.

• Overpaying for the business. A price above the independent valuation is the single most common reason a lender walks. Anchor your offer to what the numbers support.
• No down payment plan. Buyers routinely underestimate the equity injection. Know where your 10%-20% is coming from before you sign an LOI.
• Forgetting post-close working capital. Financing the purchase but not the first few months of operating cash is how a healthy acquisition strangles itself. Build it into the loan.
• Choosing the wrong tool for the term. Using short-term, factor-rate financing to fund a long-term purchase creates payments the business cannot sustain. Reserve fast money for short needs.
• Weak or late documentation. Underwriting runs on paper. Missing tax returns or a slow response to a document request can cost you the deal while the seller talks to the next buyer.
