How to Buy a Business With an SBA Loan

What the SBA actually does — and doesn't

The Small Business Administration doesn't lend you money. It guarantees a portion of a loan made by a bank, credit union, or non-bank SBA lender, which lowers the lender's downside and lets them approve deals they'd otherwise decline. That distinction matters in practice: two SBA lenders looking at the same acquisition can reach opposite conclusions, because the SBA sets the outer boundaries and each lender layers its own credit policy on top. If one lender declines your deal, it is genuinely worth taking the same package to two or three others.

For business acquisitions, the relevant program is 7(a), which can be used for goodwill, working capital, equipment, and real estate in one loan. The 504 program is built for fixed assets — owner-occupied real estate and heavy equipment — so it typically only enters an acquisition when significant real property is part of the purchase.

How much cash do you need?

SBA rules generally require a minimum 10% equity injection on a complete change of ownership. Two things are widely misunderstood about that number:

• It is a floor, not the market rate. Lenders regularly ask for 15–25% on deals with thin cash flow, heavy goodwill, an inexperienced buyer, or a volatile industry. The 10% figure is what the program permits, not what a given credit committee will accept.
• Not all of it has to be your cash. A seller note placed on full standby — no payments of principal or interest for a defined period at the start of the loan term — can generally count toward part of the required injection. Gifted funds, retirement rollovers, and equity from a co-investor are other common sources.

Budget separately for closing costs: the SBA guarantee fee, lender packaging fees, a third-party business valuation, legal review of the purchase agreement, and post-close working capital. Buyers who fund the down payment down to their last dollar and then hit a slow first quarter are the most common form of avoidable failure in this asset class.

What the underwriter is actually looking at

Acquisition underwriting comes down to one question: after debt service and a reasonable owner's salary, does the business still generate a cushion? Lenders express this as a debt service coverage ratio and most want meaningful headroom above 1.0x on historical, not projected, numbers. Beyond coverage, expect scrutiny on:

• Quality of earnings. Three years of tax returns that reconcile to the seller's P&L. Add-backs that can't be documented get removed from cash flow, which lowers what the lender will fund — and often the defensible purchase price. See how to value a business for how add-backs drive the multiple.
• Customer concentration. If one or two accounts drive most of the revenue and the relationship is personal to the seller, that's a downgrade in almost every credit memo.
• Your background. Direct industry experience is the strongest form of buyer credit. Adjacent management experience plus a retained key employee is the usual substitute.
• Transferability. Licenses, permits, franchise consent, and the lease all have to survive the change of ownership for the length of the loan.
• Personal financials. Credit score, liquidity after closing, and personal guarantees from anyone holding 20% or more of the buying entity.

The realistic timeline

From signed purchase agreement to funding, plan on 60–90 days. A rough sequence:

• Days 1–10 — pre-qualification. Personal financial statement, resume, and the target's financials go to lenders. You want this conversation started before you sign an LOI, not after.
• Days 10–40 — underwriting and valuation. The lender orders an independent business valuation. If it comes in below your negotiated price, the gap has to be closed by you in cash, by the seller in note or price, or the deal dies.
• Days 40–70 — approval and closing conditions. Lease assignment or new lease, entity formation, insurance, licensing, and any required standby agreements.
• Days 70–90 — funding and transition. Wire, keys, and whatever training period you negotiated with the seller.

The two levers that most reliably compress this: use an SBA-preferred lender with delegated authority, and deliver a complete document package the first time. The two things that most reliably blow it up: a landlord who won't assign the lease, and a seller who can't produce clean records.

Where SBA acquisition deals fall apart

Practical sequence for a first-time buyer

Talk to two or three SBA-preferred lenders before you have a deal, so you know your realistic ceiling. Then search within it, verify earnings yourself rather than trusting a broker's adjusted-EBITDA summary, and structure a seller note into the offer from the start — it improves the credit picture and keeps the seller invested in a clean handoff. If your cash injection is the binding constraint, the low-cash structures in our companion guide on buying a business with no money pair directly with a 7(a) loan.
