Acquiring an existing business is one of the most popular uses of SBA 7(a) loans, and for good reason. Buying a business with established revenue, customers, and systems dramatically reduces the startup risk that makes lenders nervous. In fiscal year 2025, business acquisitions represented approximately 20% of all SBA 7(a) loan approvals, with an average acquisition loan size of $780,000. The SBA 7(a) program can finance up to $5 million for a business purchase, covering the purchase price, working capital, and even commercial real estate included in the deal.
This guide covers the specific mechanics of using SBA loans to buy a business: how valuations work, what lenders require, how to structure seller notes and equity injections, and the complete timeline from letter of intent to closing.
Why SBA 7(a) Is the Go-To Acquisition Loan
The SBA 7(a) program dominates small business acquisition financing for several compelling reasons. First, SBA 7(a) loans finance goodwill, which is the intangible value of a business above the fair market value of its tangible assets. Most small businesses derive the majority of their value from goodwill (customer relationships, brand recognition, trained workforce, proprietary processes), and conventional lenders are reluctant to lend against these intangible assets. The SBA guarantee makes lenders comfortable financing goodwill-heavy acquisitions.
Second, SBA 7(a) acquisition loans offer terms up to 10 years, with interest rates capped at prime plus 2.75% for loans over $50,000 (currently around 10.25% as of early 2026). While these rates are higher than SBA 504 rates, the 10-year amortization keeps monthly payments manageable relative to business cash flow. Third, the equity injection requirement is typically just 10% of the total project cost, compared to the 25-40% down payment conventional lenders require for business acquisitions.
Business Valuation Methods for SBA Loans
SBA lenders use specific valuation methodologies to determine if the purchase price is reasonable. Understanding these methods is critical because if the lender's valuation does not support the agreed price, the loan will not be approved at the requested amount.
Seller's Discretionary Earnings (SDE) Multiple
The SDE method is the most common valuation approach for small businesses (under $5 million in annual revenue). SDE starts with net income and adds back the owner's salary, owner's benefits, interest, depreciation, amortization, and any one-time or non-recurring expenses. The resulting SDE figure represents the total economic benefit available to a single owner-operator.
The SDE is then multiplied by an industry-specific multiple to arrive at the business value. Here are typical SDE multiples by industry for SBA-financed acquisitions:
- Restaurants (independent): 1.5x to 2.5x SDE
- Restaurants (franchise): 2.0x to 3.5x SDE
- Dental practices: 1.8x to 2.8x SDE (or 65-85% of collections)
- Veterinary practices: 4.0x to 7.0x SDE (high demand, limited supply)
- Medical practices: 1.5x to 3.0x SDE (varies widely by specialty)
- HVAC/plumbing/electrical: 2.0x to 3.5x SDE
- Auto repair: 1.5x to 2.5x SDE
- Insurance agencies: 1.5x to 2.5x annual commissions
- Accounting firms: 1.0x to 1.5x annual revenue
- IT managed service providers: 2.5x to 4.0x SDE (or 1.0-1.5x annual recurring revenue)
- Manufacturing: 3.0x to 5.0x SDE (asset-heavy businesses command higher multiples)
- Landscaping/lawn care: 1.5x to 2.5x SDE
- Childcare/daycare: 2.0x to 3.5x SDE
- E-commerce: 2.5x to 4.0x SDE (content/brand businesses higher)
EBITDA Multiple
For larger businesses (revenue above $5 million), lenders typically use EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) multiples rather than SDE. EBITDA multiples are generally higher than SDE multiples because they do not include owner compensation as an add-back. Typical EBITDA multiples for SBA acquisitions range from 3x to 6x depending on the industry, growth rate, and customer concentration.
Asset-Based Valuation
Some businesses are valued primarily on their tangible assets: real estate, equipment, inventory, and accounts receivable. This method is most common for manufacturing businesses, construction companies, and asset-heavy service businesses. The SBA lender will order an appraisal of the tangible assets and compare the result to the purchase price. Any excess of purchase price over tangible asset value is classified as goodwill.
Goodwill Financing and Its Limits
Goodwill is the single most important concept in SBA acquisition lending. When you buy a business for $2 million and its tangible assets (equipment, inventory, real estate) are worth $600,000, the remaining $1.4 million is goodwill. The SBA will finance goodwill, but lenders scrutinize it carefully because goodwill has no liquidation value if the business fails.
Most SBA lenders become cautious when goodwill exceeds 50-60% of the total purchase price. At goodwill levels above 70%, some lenders will decline the loan entirely or require additional equity injection. To get comfortable with high-goodwill acquisitions, lenders look for:
- Strong, consistent historical cash flow (3+ years of stable or growing SDE)
- Low customer concentration (no single customer representing more than 15-20% of revenue)
- Transferable contracts, licenses, and relationships
- A reasonable transition plan with seller involvement post-closing
- Industry-appropriate valuation multiples (not overpaying relative to comparables)
Asset Purchase vs. Stock Purchase
The legal structure of the acquisition matters for SBA financing. Most SBA-financed acquisitions are structured as asset purchases rather than stock purchases. Here is why and when each structure applies:
Asset Purchase (Preferred by SBA Lenders)
In an asset purchase, the buyer acquires the specific assets of the business (equipment, inventory, customer lists, trade name, goodwill) but does not acquire the legal entity itself. The seller retains the corporate entity along with its historical liabilities. SBA lenders strongly prefer asset purchases because they eliminate the risk of undisclosed liabilities (lawsuits, tax obligations, environmental issues) transferring to the buyer.
Additional benefits of asset purchases for SBA borrowers include the ability to step up the tax basis of acquired assets (creating larger depreciation deductions), selective assumption of liabilities (the buyer can choose which contracts and obligations to assume), and cleaner SBA collateral documentation.
Stock Purchase (Less Common but Sometimes Necessary)
In a stock purchase, the buyer acquires ownership of the entire corporate entity, including all assets, liabilities, contracts, and obligations. Stock purchases are sometimes necessary when the business holds non-assignable contracts, professional licenses tied to the entity, or government certifications (like 8(a) or SDVOSB status) that would be lost in an asset transfer. SBA lenders will finance stock purchases but typically require more extensive due diligence, including environmental assessments and comprehensive liability reviews.
Seller Note Requirements
Seller notes (also called seller financing or seller carry-back) are a common component of SBA acquisition transactions. A seller note is a loan from the seller to the buyer for a portion of the purchase price. SBA lenders often require or strongly encourage seller notes for several reasons:
- Seller confidence signal: If the seller is willing to finance part of the price, it signals confidence that the business will perform well enough for the buyer to service the debt.
- Reduced lender exposure: A seller note reduces the amount the SBA lender needs to provide, lowering their risk.
- Alignment of interests: A seller note keeps the seller financially invested in the buyer's success during the transition period.
SBA rules for seller notes require that the note be on full standby for a minimum of 24 months. "Full standby" means no payments of principal or interest during the standby period. After the standby period, the seller note can begin amortizing, but the terms cannot be more aggressive than the SBA loan. Typical seller notes represent 5% to 20% of the purchase price, carry interest rates of 4% to 7%, and amortize over 5 to 7 years after the standby period ends.
Equity Injection Rules
The SBA requires that the buyer contribute an equity injection (down payment) of at least 10% of the total project cost for a standard acquisition, or 15% to 20% for higher-risk transactions. The equity injection can come from several sources:
- Cash savings: Personal savings or liquid investments. The most straightforward source.
- Seller note on full standby: As described above, a seller note with no payments for 24 months can count as equity injection.
- Retirement funds (ROBS): Rollovers as Business Startups (ROBS) allow the buyer to use 401(k) or IRA funds as equity injection without triggering early withdrawal penalties. ROBS requires setting up a C-corporation and a new 401(k) plan, and costs $3,000 to $7,000 in setup fees.
- Gifts from family: Gifts are acceptable with a signed gift letter confirming no repayment obligation.
- Home equity: A home equity line of credit (HELOC) can fund the equity injection, though the HELOC payments will be included in the buyer's global debt service calculation.
The equity injection must be documented with a clear paper trail. Lenders will trace the source of funds back at least 60 to 90 days through bank statements. Undocumented cash deposits or recent large transfers from unknown sources will be flagged and must be explained.
Due Diligence for SBA Acquisitions
SBA lenders expect thorough due diligence on any acquisition they finance. While the lender conducts its own underwriting, the buyer should independently verify the following before submitting a loan application:
- Financial verification: Obtain three years of tax returns (corporate and personal for the seller), interim financial statements, and bank statements. Verify that the revenue and expenses on the tax returns match the financial statements. Identify any discrepancies or addbacks that need documentation.
- Normalized cash flow: Build a normalized SDE or EBITDA calculation that removes non-recurring items, above-market owner compensation, personal expenses run through the business, and one-time costs. This normalized cash flow is what the lender will use to evaluate the acquisition.
- Customer concentration: Analyze the customer base. If any single customer represents more than 15-20% of revenue, the lender will view this as a risk factor. Document the contractual relationship with major customers and their likelihood of continuing post-acquisition.
- Employee assessment: Identify key employees and their likelihood of staying post-acquisition. If the business depends on 2-3 key people, their retention is critical to the lender's cash flow projections.
- Legal review: Review all contracts, leases, licenses, permits, and pending litigation. The lease is especially important because SBA lenders require that the buyer have a lease with a remaining term at least equal to the loan term (10 years for a 7(a) acquisition loan).
- Asset verification: Confirm the existence and condition of all tangible assets included in the sale. Equipment should be inspected, and inventory should be counted.
LOI to Closing Timeline
Here is a realistic timeline for an SBA-financed business acquisition from the initial letter of intent through closing:
- Week 1-2: Letter of Intent (LOI). Buyer and seller agree on price, general terms, and due diligence timeline. The LOI is non-binding but establishes the framework for the deal.
- Weeks 2-6: Due diligence. Buyer reviews financial records, legal documents, customer data, and operations. The buyer's accountant and attorney conduct their reviews.
- Weeks 4-6: SBA loan application. Submit the complete application package to the SBA lender, including financial analysis, purchase agreement (or draft), personal financial statements, tax returns, and a business plan describing the buyer's management strategy.
- Weeks 6-10: Underwriting and SBA authorization. The lender underwrites the loan and submits to the SBA (or approves under delegated authority if a Preferred Lender). The SBA issues a loan authorization.
- Weeks 10-12: Closing preparation. Final purchase agreement executed, escrow opened, third-party reports completed (appraisals, environmental if real estate is included), loan documents prepared.
- Weeks 12-14: Closing. Loan documents signed, funds disbursed into escrow, purchase completed, ownership transfers.
Total timeline from LOI to closing: 12 to 16 weeks for a straightforward acquisition. Complex deals involving multiple entities, real estate, or SBA 504 components can take 16 to 24 weeks.
Earnouts and SBA Compatibility
An earnout is a contractual provision where a portion of the purchase price is contingent on the business achieving specified performance targets after the acquisition closes. Earnouts are common in small business acquisitions because they bridge valuation gaps between buyer and seller expectations.
The SBA has a complicated relationship with earnouts. The SBA loan will not finance the contingent portion of the purchase price (because the final price is unknown at closing), but the SBA does allow earnout provisions as long as:
- The SBA loan finances only the fixed, non-contingent portion of the purchase price
- The earnout payments are subordinate to the SBA loan and do not create a cash flow burden that threatens debt service
- The earnout terms are disclosed to the lender and documented in the purchase agreement
- The total purchase price (including maximum earnout) is supported by the business valuation
A common structure for SBA-compatible earnouts: the buyer pays 80% of the agreed purchase price at closing (financed by the SBA loan), with the remaining 20% paid over 2-3 years contingent on the business maintaining at least 90% of its trailing revenue. This structure gives the seller upside protection while keeping the SBA loan amount conservative.
Keys to a Successful SBA Acquisition
- Get pre-qualified before making an offer. Many deals fall apart because the buyer signs an LOI before confirming they can get SBA financing. Talk to an SBA lender before making offers.
- Work with experienced professionals. Use a business broker, CPA, and attorney who have SBA acquisition experience. The nuances of SBA-compliant deal structures are not obvious to generalists.
- Be realistic about valuation. Lenders will not approve loans based on optimistic projections. The purchase price must be justified by historical financial performance, not future potential.
- Plan the transition. Lenders want to see a credible transition plan that includes seller involvement for 30 to 90 days post-closing. Abrupt ownership changes increase risk.
- Keep the seller engaged. A seller note on standby keeps the seller financially motivated to ensure a smooth transition. Build the seller note into your deal structure from the beginning.
SBA acquisition financing is the most practical path to business ownership for most buyers. The combination of low equity injection requirements, goodwill financing, and favorable terms makes it possible to acquire a profitable business with significantly less upfront capital than conventional financing requires. The key is understanding the specific rules and structuring your deal to align with what SBA lenders need to see.
