SBA 7(a) for buying a business: the rules that decide your deal

The SBA 7(a) programme is how most first-time buyers finance a Main Street purchase. It also quietly dictates the shape of the deal: how much cash you must put in, how the seller may be paid, how long they may stay, and how much coverage the business must show.

The rules that change the deal, not just the paperwork

These come from SBA's own standard operating procedure, which is published — so unlike most acquisition folklore, they can be checked. The current edition is SOP 50 10 8, effective 1 June 2025. A new one, SOP 50 10 8.1, applies to any application that receives an SBA loan number on or after 1 October 2026, and it changes several of the rules below — each is marked. If your purchase is in progress across that date, the edition that governs your file is the one in force when the loan number is issued, not when you signed the LOI.

Rule	What it means for you
Equity injection: at least 10%	Of total project cost, from you or a qualifying source. Nothing borrowed against the business itself.
Seller note toward the injection: up to half	A seller note can count toward the required injection only if it is on full standby — no payments — and it cannot cover more than 50% of the injection. See seller notes.
Debt-service coverage: 1.15×, rising to 1.25×	1.15× under the current edition, and 1.25× on loans from 1 October 2026 for initial acquisitions, owner buyouts and ESOP deals — measured on past results, not projections. 1.10× on 7(a) Small loans up to $350,000 under the current edition — but from 1 October 2026 a 7(a) Small loan may not be used for a change of ownership at all, so a small purchase is underwritten as a standard 7(a). At least 1.00× on a global basis either way. Details in DSCR.
Seller stays 12 months at most — 24 from 1 October 2026	Consulting after a change of ownership is capped at twelve months including extensions under the current edition, and at twenty-four under SOP 50 10 8.1. Either way the seller may not stay on as an officer, director, stockholder or employee — only as a contracted consultant. "He'll stay a couple of years to hand over the customers" needs to be written as something the rule allows.
No earnouts	Contingent, performance-based payments to the seller are not permitted in a change of ownership; a price rebate mechanism is treated differently. Plan the price accordingly.
Lease term covers the loan	Remaining term, including options you control, at least as long as the loan — see lease assignment.

What a lender will ask you for

Three years of business tax returns and interim statements, reconciled — not the seller's spreadsheet
Your personal financial statement, tax returns and résumé; industry experience matters to the credit decision
A business plan with projections that a stranger can follow
The lease, the licences, and the purchase agreement
A business valuation, which the lender orders for change-of-ownership loans

Guarantees are personal: owners of 20% or more generally guarantee the loan, and on a Main Street deal that is you. An SBA loan is not a way to buy a business without risk; it is a way to buy one with less cash.

The timeline nobody plans for

Sixty to ninety days from a signed letter of intent to funding is normal, and every missing document adds a week. The pattern that wastes months is familiar: the deal is agreed, the lender starts, and only then does someone discover that the earnings rest on unprovable add-backs, or that the lease has eighteen months left. Both are answerable in an afternoon, at the beginning.

Questions buyers ask

How much money do I need down for an SBA 7(a) business acquisition?

At least 10% of total project cost as an equity injection under SOP 50 10 8. Up to half of that requirement can be met with a seller note, but only if the note is on full standby with no payments during the standby period. The rest must be your own money or another qualifying source.

Can the seller stay on to help after an SBA-financed sale?

Briefly, and only in one shape. The seller may not remain an officer, director, stockholder or employee of the business; if a transition is needed, the business may contract the seller as a consultant. That contract is capped at twelve months in total including extensions under SOP 50 10 8, and at twenty-four months under SOP 50 10 8.1, which applies to loans from 1 October 2026. A handshake arrangement to "stay on and help" has to be written as a consulting contract inside the cap before it reaches the loan file.

Are earnouts allowed with SBA financing?

No. Contingent, performance-based payments to the seller are not permitted in an SBA change-of-ownership transaction, though a price rebate structure is treated differently. If your deal depends on an earnout, the structure has to change or the financing does.
