Buying a business with an SBA loan
Escrita el 2026-07-18 · Draft — pending review
Buying an existing business is one of the most common uses of SBA 7(a) financing, and for good reason: you are buying cash flow that already exists, which is exactly what lenders like to lend against. It is also a file with more moving pieces than almost any other loan. Here is how the pieces fit.
Why lenders like acquisitions — and what they worry about
An existing business has history: tax returns, customers, staff, a track record. That solves the biggest startup problem. What it introduces instead is a transfer question: will the cash flow survive the change of ownership? The seller's relationships, know-how, and reputation walk out the door with them. Every part of an acquisition file — the valuation, the transition plan, your resume, the working capital after closing — is really answering that one question.
The money structure
A typical SBA acquisition stack has three or four layers: your equity injection, the SBA 7(a) loan, often a seller note, and sometimes working capital built into the loan.
The injection rules are specific. SBA generally requires at least 10% of the total project cost from the borrower for a change of ownership. A seller note can substitute for up to half of that requirement, but only if it is on full standby for the life of the loan — no payments to the seller until the SBA loan is done. That means at least 5% comes from you in cash regardless. Total project cost includes more than the purchase price: working capital, inventory adjustments, closing costs, and transition costs all belong in the budget, and the 10% is measured against all of it.
A seller note beyond the injection portion is common and useful on ordinary repayment terms too — it keeps the seller invested in your success. All of it must be disclosed and documented; a side agreement with the seller that the lender does not know about is a serious problem, not a shortcut.
The valuation
For SBA acquisitions, an independent business valuation is generally part of the file — commonly ordered by the lender from a qualified third party, not something you or the seller commission to taste. If the agreed price runs meaningfully above the supportable value, the deal has to be restructured: price comes down, seller financing bridges the gap, or you bring more equity. Build your expectations around this early. A price that "felt right" across the negotiating table still has to survive an appraisal by someone with no stake in the outcome.
Due diligence on the seller's numbers
You are buying the numbers, so verify the numbers. The standard package: several years of the seller's business tax returns and financial statements, an add-back schedule (owner salary, personal expenses, one-time items — reconstructed honestly, not optimistically), the debt schedule, AR and AP agings, inventory reality, customer concentration, and the lease or property situation.
Two flags deserve special attention. First, revenue that depends on the seller personally — their license, their relationships, their name on the door. Second, anything the tax returns cannot support: "the books don't show it, but it really makes more" is a sentence that should end conversations, because a lender cannot lend against it and neither should you.
Get help here. An SBDC advisor costs nothing and has watched many of these deals; an accountant reviewing the returns is money well spent before you are committed.
The transition story
Lenders read transition plans closely because transitions are where acquisitions fail. Yours should answer, concretely: What is your relevant experience? Which key employees stay, and do they know? How are top customer relationships being handed over? Is the seller staying on for a training period, and on what written terms? What working capital cushions the first months — which almost always cost more than projected?
If ownership is changing only partially — a partner buyout — the same logic applies with its own rules; lenders will look hard at why the partner is leaving and what their departure does to operations.
The eligibility layer
The standard SBA screens still apply underneath everything: a for-profit U.S. operating business, SBA size standards, eligible owners (with personal guarantees generally expected from 20%-or-more owners), federal obligations current, and the credit-elsewhere test. The occupancy rules apply if real estate rides along — an existing building generally needs your business using at least 51% of it. None of this is exotic, but each item is a checkbox someone must verify, and clean files close faster.
A realistic sequence
Talk to lenders before you sign anything binding — early conversations shape price and structure while you can still negotiate. Get the seller's real numbers under a confidentiality agreement and have them reviewed. Build the full project budget, including working capital and your 10%. Negotiate structure — price, seller note, standby terms, training period — knowing the valuation will test it. Then assemble the file once, completely, and expect the process to take months rather than weeks.
Every rule cited here is current as of this writing and worth verifying against SBA's current rules and your lender's policy — acquisition rules are among the ones SBA refines most often. The deals that close are rarely the cleverest ones. They are the documented ones.
