The SBA 7(a) program is the financing engine behind the modern self-funded ETA market. If you are buying a $2–10M business with under a million dollars of personal capital, this is almost certainly how you’ll close.
This guide explains how it actually works in 2026 — not how a lender’s marketing brochure describes it. We cover the parts buyers consistently misunderstand: how equity injection is calculated, what counts as “outside equity,” when the partner-buyout exception applies, and the questions to ask a lender before you let them control the timeline of your deal.
A note on this guide. This is a research-and-synthesis piece, not a war-story piece. It draws on the SBA SOPs (cited by section), publicly available lender materials, podcast interviews with practitioners, and conversations with active borrowers and lenders. The author is not an SBA-licensed lender or attorney; verify specific provisions with a participating lender or counsel before relying on them in a transaction.
What is the SBA 7(a) program?
SBA 7(a) is the Small Business Administration’s flagship loan guaranty program. The SBA itself does not lend money. Instead, the SBA guarantees a portion (typically 75–85%) of a loan made by a participating bank or non-bank lender. That guaranty reduces the lender’s risk and lets them extend longer terms, lower equity requirements, and looser collateral standards than conventional lending.
For business acquisitions, the program’s defining features are:
- Loan amounts up to $5 million for the standard 7(a). (Larger amounts route through the 504 program or conventional lending.)
- Up to 10-year terms for goodwill and business assets; longer (up to 25 years) for real estate.
- Variable rates typically pegged to the Wall Street Journal Prime Rate plus a lender spread. Rate caps are set by SBA SOP.
- No mandatory prepayment penalty on terms ≤15 years, after a brief seasoning period, in most cases.
- Equity injection requirement — the buyer must put real money into the deal. The headline is “10%,” but the math is more nuanced (see below).
If you want to model what payments look like, use the SBA 7(a) Calculator.
The equity injection rule, accurately
The most-misunderstood rule in the program. Here is what it actually says.
For a business-acquisition loan, the buyer must contribute at least 10% equity of the total project cost. “Total project cost” includes the purchase price, working capital, closing costs, and any other use of proceeds.
Half of that 10% (i.e., 5%) must come from the buyer’s own resources that are not borrowed against the assets being acquired. The other 5% can come from:
- Seller financing on standby — meaning the seller note is fully on standby (no payments) for at least the first 24 months. Seller notes that begin amortizing immediately do not count toward the equity injection.
- Outside investor capital — which counts as equity injection but creates ownership obligations and may require additional underwriting.
- Other documented equity sources approved by the lender.
What this means in practice: if you’re buying a business for $3 million with $500K of working capital and $50K of closing costs, the project total is $3,550,000. Your equity injection minimum is $355,000 — and at least $177,500 of that has to be your money, not borrowed.
The 10% headline obscures the second-tier rule (the half-must-be-yours rule), and that is the rule that traps buyers who plan to layer in seller financing too aggressively.
The partner-buyout exception (and why it matters)
There is a specific exception relevant to existing partners buying out other partners: the SBA permits a 7(a) loan with no equity injection from the buyer if the buying partner has been a 20%+ owner of the business for at least 24 months and meets specific operational involvement requirements.
If you are searching for a business and the seller asks you to take a small partnership stake first to “set up” a future SBA-financed buyout, do not assume that automatically qualifies you for the exception. The 24-month clock and the operational tests are real. Talk to a lender experienced with this structure before you agree to the partnership stake.
Working capital — the line item buyers underestimate
Most acquisition loans wrap a working capital component into the loan. This is not optional generosity from the lender; it is necessary because:
- The seller usually retains accounts receivable through closing (or, even if AR transfers, you’ll be funding the operating gap until customers pay).
- Inventory typically transfers but you’ll need additional inventory to operate at scale.
- Payroll runs continuously, but you may not bill a customer for 30–60 days post-close.
Standard practice is to size the working capital component as a multiple of monthly operating expenses or as a percentage of revenue, depending on the business’s cash conversion cycle. Service businesses with quick collections need less; project-based businesses or distributors with longer cycles need more.
A common error: buyers accept a working capital component sized to the lender’s standard ratio without modeling whether it will actually carry them through the post-close trough. Ask your lender to show you how they sized it. If the answer is “we always do X% of revenue,” push for a specific cash-flow projection and adjust accordingly.

What the SBA does not directly fund
The 7(a) program is broad but not unlimited. A few items the program will not directly fund:
- The buyer’s personal living expenses during the search or transition. This is your problem.
- Cash to the seller as a “transition payment” unless it is part of the negotiated purchase price.
- Investments unrelated to the acquired business (i.e., you can’t use 7(a) proceeds to buy an entirely separate business or investment property at closing).
There are also disqualifying business types — businesses primarily engaged in passive activities, lending, or speculative activities. Most operating SMBs qualify; specialty cases (medical practices in some states, agricultural operations, certain franchises) have additional rules. Verify with your lender early.
Choosing a lender — the question that decides everything else
Not all SBA 7(a) lenders are equal, and the difference between a good lender and a bad lender is often the difference between closing in 90 days and watching your deal die at month six.
Three categories of lender, in rough order of speed and acquisition expertise:
- Preferred Lender Program (PLP) lenders specializing in acquisitions. These lenders close most decisions internally, do not need every package routed back to the SBA, and have underwriters who understand acquisition deals. They are the fastest. Examples in the market include several non-bank lenders and select community banks; we’ll publish a current list as a separate resource.
- General PLP lenders. Speed is fine but acquisition expertise varies. You may end up educating your loan officer on basic acquisition mechanics — manageable, but a tax on your time.
- Non-PLP lenders. Each loan goes through the SBA itself. Slower; sometimes much slower. Acceptable only if a specific banker has a track record with you and the deal economics.
Questions to ask any lender before you commit:
- “How many sub-$5M business-acquisition loans did you close in the last 12 months?” If the answer is below 10, find another lender unless you have a very specific reason.
- “What is your average time from full application to closing on an acquisition deal?” Acceptable: 60–90 days. Unacceptable: “It depends.”
- “Will my deal be underwritten in-house or sent through PLP delegation?” PLP delegation is meaningfully faster.
- “Who owns my file day-to-day, and how do I reach them?” The answer should be a name and a direct line, not a 1-800 number.
- “What is your guaranty fee structure on this loan size?” SBA guaranty fees are set by SBA but lenders sometimes layer in additional origination or packaging fees. Get them all on paper before you sign.
Common LOI/term-sheet traps that surface during SBA underwriting
Several issues typically don’t reveal themselves until the lender’s underwriter starts asking questions. Smart buyers anticipate them in the LOI:
- Working-capital peg disputes. If your LOI does not specify how working capital will be calculated and pegged at close, expect a fight. SBA lenders will not fund through an unresolved peg dispute.
- Real estate that the seller wants to lease back. If the operating business sits on real estate the seller plans to retain and lease to you, the lease structure has to clear SBA rules (arms-length, market rate, term that supports the loan amortization). Lenders will reject leases that look like extracted seller value.
- Earn-outs. SBA loans generally don’t fund earn-out structures cleanly. If part of the price is contingent, you and the seller will need to land on a clean fixed-price structure (often by reframing the earn-out as a smaller, separately documented seller note on standby).
- Working capital exclusions. Buyers sometimes assume they’re getting “all the working capital” only to discover at close that the seller is keeping cash, AR over X days, or specific inventory. Spell out exactly what is included and what is excluded in the LOI.
