You found a business worth buying. The owner is ready to sell. The financials check out. The customer base is stable and the revenue is predictable. There is just one problem: the purchase price is $800,000 and you do not have $800,000 sitting in a bank account.
That is where business acquisition loans come in. Instead of building a company from scratch, you buy one that is already generating revenue. The loan covers most of the purchase price, and the business itself, its cash flow, equipment, receivables, and customer contracts, serves as the basis for repayment. You bring a down payment, the lender funds the rest, and the business pays back the loan from its own earnings.
Here is how acquisition financing works, what it costs, how to qualify, and how to avoid the mistakes that turn a solid acquisition into a financial headache.
How Business Acquisition Loans Work
A business acquisition loan funds the purchase of an existing business. The structure is similar to buying a house: you make a down payment, a lender finances the balance, and you repay the loan over a set period with interest. The key difference is that the business's own cash flow is what makes the payments, not your personal income.
Lenders underwrite acquisition loans based on the target business's financial performance, not just your personal credit. They want to see that the business generates enough cash flow to cover the loan payments with room to spare. The standard measure is a debt service coverage ratio (DSCR) of 1.25x or higher, meaning the business earns $1.25 for every $1.00 in annual loan payments.
The underwriting process is more involved than a standard business loan because the lender is evaluating two things at once: the quality of the business being acquired, and your ability to run it after closing. Expect a detailed review of the target company's tax returns, profit and loss statements, customer concentration, lease agreements, and key employee retention risk. The lender is asking one question: will this business continue to perform under new ownership?
Asset Sale vs. Stock Sale
Most small business acquisitions are structured as asset sales, where you buy the business's equipment, inventory, customer contracts, and goodwill rather than purchasing the legal entity itself. Asset sales protect you from inheriting unknown liabilities. Stock sales, where you buy the company's shares, are more common in larger transactions. Your lender and attorney will have strong opinions on this. Listen to them.
Types of Business Acquisition Financing
There is no single loan product for acquisitions. Most deals use one or a combination of these funding sources.
SBA 7(a) Loans
The SBA 7(a) program is the most popular financing vehicle for small business acquisitions under $5 million. The SBA does not lend directly. It guarantees a portion of the loan, which reduces the bank's risk and enables better terms for the borrower. SBA loans for acquisitions typically come with interest rates of prime plus 1.5% to 2.75%, terms up to 10 years, and down payments of 10% to 20%.
The trade off is speed and paperwork. An SBA acquisition loan takes 45 to 90 days to close. The documentation requirements are heavy: three years of business tax returns, personal financial statements, a detailed business plan, a professional business valuation, and a management resume demonstrating relevant experience. If you need to close in 30 days, the SBA timeline probably will not work.
Conventional Bank Loans
Banks that skip the SBA guarantee can move faster and impose fewer bureaucratic requirements, but they charge higher rates and require larger down payments. Expect 20% to 30% down, rates of 6% to 12%, and terms of 5 to 7 years. Conventional loans work best for buyers with strong credit, significant liquid assets, and a target business with rock solid financials.
Many community banks and credit unions are active in acquisition lending. They know local businesses, understand regional markets, and can be more flexible than national banks. If you are buying a business in your metro area, start with the banks that already serve that business or industry.
Seller Financing
In a seller financed deal, the current owner carries part of the purchase price as a loan. You make a down payment, a bank or SBA lender funds a portion, and the seller finances the remainder. Seller notes typically carry 5% to 8% interest rates with 3 to 7 year terms and are subordinated to the primary lender's loan.
Seller financing is powerful for two reasons. First, it reduces the amount you need from a bank, which can make the deal bankable when it otherwise would not be. Second, it signals confidence. A seller who is willing to carry a note is betting that the business will continue performing under your management. Lenders view seller financing favorably for this reason. Most SBA acquisition loans include a seller note as part of the deal structure.
Alternative and Online Lenders
If you cannot qualify for SBA or conventional bank financing, alternative lenders offer acquisition loans with lower qualification requirements but higher costs. Rates range from 12% to 25%, terms are shorter (3 to 5 years), and the process is faster (1 to 3 weeks). These loans work when the opportunity is time sensitive and the business generates enough margin to absorb the higher interest cost.
Be cautious. A business term loan at 20% interest on a $500,000 acquisition adds $100,000 a year in interest expense. If the business nets $150,000 in owner earnings, you are spending two thirds of that on debt service. The math needs to work before you sign.
What Business Acquisition Loans Cost
Costs vary significantly based on the loan type, deal size, and your qualifications. Here is what to expect across the main options.
| Loan Type | Interest Rate | Down Payment | Term | Time to Close |
|---|---|---|---|---|
| SBA 7(a) | Prime + 1.5% to 2.75% | 10% to 20% | Up to 10 years | 45 to 90 days |
| Conventional bank | 6% to 12% | 20% to 30% | 5 to 7 years | 30 to 60 days |
| Seller financing | 5% to 8% | Varies (often 10% to 30%) | 3 to 7 years | Negotiated |
| Alternative lender | 12% to 25% | 10% to 20% | 3 to 5 years | 1 to 3 weeks |
Here is a concrete example. You are buying a landscaping company for $600,000. The business generates $180,000 in annual seller's discretionary earnings (SDE). You put down 10% ($60,000), the SBA lender funds $480,000 at prime plus 2.25% (roughly 10.75% total), and the seller carries a $60,000 note at 6% over 5 years.
Your monthly payments: roughly $6,500 on the SBA loan and $1,160 on the seller note, totaling $7,660 per month or $91,920 per year. The business earns $180,000 in SDE, leaving you $88,080 before taxes as owner compensation. Your DSCR is 1.96x ($180,000 / $91,920), which is healthy.
Additional costs to budget for: SBA guarantee fee (up to 3.5% of the guaranteed portion), legal fees ($5,000 to $15,000 for acquisition closing), professional business valuation ($3,000 to $10,000), and due diligence costs including accounting review ($2,000 to $5,000). On a $600,000 deal, expect $20,000 to $40,000 in total transaction costs beyond the down payment.
How to Qualify for an Acquisition Loan
Qualifying for an acquisition loan depends on three things: the quality of the business you are buying, your personal qualifications, and the structure of the deal.
The target business must be profitable. Lenders want at least two to three years of consistent financial performance. Revenue should be stable or growing. Profit margins should be healthy for the industry. Customer concentration should be low. No single customer should represent more than 15% to 20% of revenue. A business that depends on one client is one phone call away from a crisis.
Cash flow must cover debt service. The business needs to generate enough free cash flow to make the loan payments and still leave you with reasonable owner compensation. Lenders calculate the DSCR using the business's historical earnings, not your projections. If the DSCR is below 1.25x based on current performance, you will need to restructure the deal, negotiate a lower price, or bring a larger down payment.
You need relevant experience. SBA lenders and most bank lenders require the buyer to have experience in the industry or in managing a business of similar size. You do not need to have run the exact same type of company, but you need a credible story for why you can operate this business successfully. A 20 year corporate marketing executive buying a plumbing company will face skepticism. That same executive buying a marketing agency will not.
Personal credit and liquidity matter. SBA lenders want a credit score of 680 or above. They also want to see that you have liquid assets beyond the down payment, enough to cover 3 to 6 months of personal expenses. Lenders do not want a buyer who is one slow month away from personal financial stress, because that stress will affect business decisions.
A personal guarantee is standard. Every acquisition loan will require a personal guarantee from the buyer and any co-owners with 20% or more equity. If the business fails, you are personally liable for the loan balance. This is non-negotiable for deals under $5 million.
Documentation Checklist
Have these ready before you approach a lender:
- 3 years of business tax returns for the target company
- Year to date profit and loss statement and balance sheet
- Seller's discretionary earnings (SDE) or EBITDA calculation
- Personal financial statement and resume
- Business plan explaining your management approach and growth strategy
- Letter of intent (LOI) or purchase agreement
- Professional business valuation or appraisal
- List of assets included in the sale (equipment, inventory, IP, contracts)
How Business Valuation Affects Your Loan
The lender will not take your word or the seller's word for what the business is worth. They will require a professional valuation, and that number determines how much they will lend.
Small businesses are most commonly valued using a multiple of seller's discretionary earnings (SDE). SDE is net profit plus the owner's salary, benefits, one time expenses, and non-cash charges like depreciation. It represents the total economic benefit to a single owner operator.
A business with $200,000 in SDE and a 3x multiple is valued at $600,000. Multiples vary by industry, size, growth rate, and risk. Here is a rough guide.
| Business Type | Typical SDE Multiple | Key Value Drivers |
|---|---|---|
| Service businesses (owner dependent) | 1.5x to 2.5x | Revenue tied to owner, limited systems |
| Service businesses (managed) | 2.5x to 4x | Recurring revenue, management team in place |
| Retail and restaurants | 2x to 3x | Location, lease terms, brand recognition |
| Manufacturing | 3x to 5x | Equipment value, contracts, barriers to entry |
| SaaS and tech enabled | 4x to 8x | Recurring revenue, low churn, scalability |
If the seller is asking for a price significantly above what the valuation supports, the lender will only lend against the appraised value. You would need to cover the difference out of pocket or negotiate the price down. This is why getting a professional valuation early in the process saves everyone time. It sets realistic expectations before you spend months on due diligence.
Watch for Adjusted Financials
Sellers often present “adjusted” or “normalized” financials that add back personal expenses run through the business. Some adjustments are legitimate (the owner's above market salary, one time legal costs). Others are not (rent from a related party at below market rates, unpaid family labor). Your accountant should verify every add back. Lenders will scrutinize these adjustments, and so should you.
Structuring the Deal to Get Funded
The deal structure matters as much as the purchase price. A well structured acquisition is easier to finance, reduces your risk, and gives you room to operate in the first year. Here is how experienced buyers put deals together.
Combine funding sources. Most acquisitions use more than one source of capital. A typical structure for a $750,000 deal might look like this: $75,000 buyer down payment (10%), $525,000 SBA 7(a) loan (70%), and $150,000 seller note (20%). Layering funding sources lets you acquire a larger business than you could with a single loan product.
Negotiate a seller transition period. Most SBA lenders require the seller to stay on for 30 to 90 days to help with the transition. This protects you from losing key relationships, processes, or institutional knowledge on day one. Some deals include longer consulting agreements of 6 to 12 months. Build the cost of the transition into the deal.
Include working capital in the loan. You will need cash to run the business from day one. Payroll, rent, inventory, and operating expenses do not pause for a change of ownership. Many acquisition loans include a working capital component of 10% to 15% of the total loan amount. If your loan does not include working capital, make sure you have a separate line of credit or working capital loan in place before closing.
Use earnouts for uncertain value. If you and the seller disagree on price, an earnout lets you pay a base amount at closing and additional payments tied to the business hitting performance targets after the sale. For example, you pay $500,000 at closing and an additional $100,000 if the business maintains $200,000 or more in SDE for each of the next two years. Earnouts align incentives and reduce risk for the buyer.
Mistakes That Kill Acquisition Deals
Business acquisitions fail more often than they should, and usually for preventable reasons. These are the errors that cost buyers the most.
Skipping due diligence. The seller says revenue is $1.2 million. Great. Verify it. Pull the bank statements and match deposits to the reported revenue. Review tax returns, not just internal financials. Check for customer concentration. Call key customers (with the seller's permission) to gauge the relationship. Review all contracts, leases, and employee agreements. Due diligence is not optional. It is the difference between buying a business and buying someone else's problem.
Overpaying based on projections. Sellers love to talk about potential. The business could grow 30% if you just added a sales team. It could double with a better website. Lenders do not care about projections and neither should you when setting the purchase price. Pay for what the business does today, not what it might do tomorrow. If the growth were that easy, the seller would have done it themselves.
Underestimating transition risk. The previous owner knew every customer by name, managed the key vendor relationships personally, and was the only person who understood the pricing model. When that person leaves, those relationships and that knowledge leave too. Identify what lives in the owner's head versus what is documented in systems. Budget for a longer transition period than you think you need.
Ignoring the lease. If the business operates from a physical location, the lease terms can make or break the deal. A lease that expires in 8 months with no renewal option means you might be running a business with no location next year. Lenders will require a lease assignment with at least 5 years of remaining term, including options. If the landlord will not cooperate, the deal may not close.
Not having enough working capital. You used every dollar of available cash for the down payment and closing costs. Now it is day one and you need to make payroll, pay rent, and cover an unexpected equipment repair. Insufficient working capital after closing is the most common reason acquisitions struggle in the first six months. Keep at least 3 months of operating expenses in reserve, separate from the down payment.
Acquisition Financing vs. Starting From Scratch
Buying an existing business costs more upfront than a startup, but the risk profile is different. A startup has no revenue, no customers, and no track record. An acquisition has all three from day one. Here is how the math compares.
A startup might require $50,000 to $100,000 in initial capital and take 12 to 24 months to reach profitability. Many never do. An acquisition of a business generating $150,000 in SDE at a 3x multiple costs $450,000, but you are profitable from the first month. The acquisition buyer takes on more debt but less operating risk.
Lenders strongly prefer acquisition financing over startup lending for this reason. A business with three years of financial history is far easier to underwrite than a business plan with projections. SBA lenders will finance 80% to 90% of an acquisition but only 50% to 70% of a startup, and at higher rates.
The Bottom Line on Business Acquisition Loans
Buying an existing business is one of the most direct paths to business ownership. The business has customers, revenue, employees, and systems already in place. Your job is to finance the purchase at terms that leave enough cash flow for both debt service and owner compensation, then operate the business at least as well as the previous owner.
The best acquisition loans come from matching the right funding source to the deal. SBA 7(a) loans are the gold standard for deals under $5 million when you have the time and qualifications. Seller financing reduces the amount you need from a bank and signals seller confidence. Conventional bank loans and alternative lenders fill the gaps when SBA does not fit.
Before you start the process, get clear on three numbers: the business's true SDE, the maximum purchase price that leaves you with acceptable owner compensation after debt service, and the total cash you need at closing including the down payment, transaction costs, and working capital reserves. Check your eligibility to see which acquisition financing options fit your situation.
Frequently Asked Questions
What is a business acquisition loan?
A business acquisition loan is financing used to purchase an existing business. The loan covers the purchase price and sometimes working capital for the transition period. Common options include SBA 7(a) loans, conventional bank loans, seller financing, and alternative lenders. The acquired business's assets and cash flow serve as collateral, and the business's earnings are used to repay the loan over the loan term.
How much do you need to put down to buy a business?
Most acquisition loans require 10% to 30% down. SBA 7(a) loans typically require 10% to 20% of the purchase price. Conventional bank loans require 20% to 30%. Seller financing arrangements vary, with some sellers accepting 10% or less when they carry a significant portion of the purchase price. Stronger business cash flow and buyer qualifications generally result in lower down payment requirements.
Can you buy a business with an SBA loan?
Yes. The SBA 7(a) program is one of the most popular ways to finance a business acquisition under $5 million. SBA loans offer interest rates of prime plus 1.5% to 2.75%, terms up to 10 years, and down payments as low as 10%. The process takes 45 to 90 days and requires extensive documentation including business tax returns, a professional valuation, and a detailed business plan.
How do lenders determine how much a business is worth?
Lenders rely on professional business valuations based on multiples of seller's discretionary earnings (SDE) or EBITDA. Small businesses typically sell for 2x to 4x SDE. Larger businesses sell for 3x to 6x EBITDA. The valuation considers the business's financial performance, industry, growth trends, customer concentration, asset values, and comparable sales. Lenders will only finance up to the appraised value, not the asking price.
What credit score do you need to buy a business?
SBA acquisition loans generally require a minimum credit score of 680, with some lenders preferring 700 or above. Conventional bank loans require 680 to 720. Alternative lenders and seller financing may work with scores as low as 600 at higher rates. Beyond the credit score, lenders evaluate the business's cash flow, your relevant experience, and your post closing liquidity.
