The rules for buying a business are changing on October 1

On October 1, 2026, the SBA's new SOP 50 10 8.1 takes effect. It applies to any loan issued an SBA number on or after that date, and it rewrites the acquisition rules more than any update since June 2025. If your loan number comes through on September 30, you're on the old rules. October 1, you're on the new ones.

None of these changes are dealbreakers. But together they change how you structure a deal, how you diligence it, and how much cash you need to bring. Here's what's actually different, and what it means if you're the one buying.

First, every deal now gets sorted into one of four boxes

This is the framework everything else hangs on. Under the new rules, your acquisition gets classified into one of four categories, and the box determines your down payment, your coverage hurdle, and whether you need a Quality of Earnings report.

1. Initial Acquisition is the default, and it's where most searchers and first-time buyers land: you're buying a business you didn't previously own or work in. It carries the strictest terms, a firm 10% injection and a 1.25x coverage test.

2. Business Expansion is for existing operators buying a competitor or add-on in the same industry. The old rules made this hard with a geography test and an identical-ownership requirement. Both are gone, so more roll-up and add-on deals now qualify, and this box gets the friendlier 1.15x hurdle plus combined cash flow underwriting.

3. Owner Buyout covers partner buyouts and partial changes of ownership, where at least one original owner stays on and guarantees the loan.

4. ESOP & Cooperative covers employee-ownership exits, and the new rulebook treats them well: exempt from both the injection and the QoE requirements.

If you don't fit a specific box, you're an Initial Acquisition by default, and the lender has to document why in writing to treat you as anything else. So knowing your box, early, is the first structuring decision you make.

The down payment got harder to skip, and pickier about where it comes from

Two things changed here.

First, the floor firmed up. On an Initial Acquisition, the 10% injection can no longer be reduced or waived. That lender flexibility is gone.

Second, and this is the subtler shift, the SBA now sorts your down payment dollars into two buckets. Unlimited sources (your own unborrowed cash, certain personal loans, no-strings grants) can fund as much of the injection as needed. Limited sources (a seller note on full standby, other standby debt, and passive investor equity under 20%) are now capped together at half the injection.

Here's why that matters. Under today's rules, passive investor cash counts like any other cash in the buyer group. Under the new rules, it shares that same half-cap bucket with the seller note. Put plainly: at least half your down payment has to come from unlimited sources, and for most buyers, that means your own cash.

There's a sharper edge for self-funded searchers. If passive investor money goes toward your injection, those investors can only take tax distributions until the SBA loan is paid off, potentially a decade of no real return, when their alternative is an LP position in a fund that pays out during the hold. That's a harder raise. If you're funding a down payment with outside capital, read this section twice.

The coverage test only counts what the business already earns

Today, an acquisition has to clear a 1.15x debt service coverage ratio, and projections can count toward it. That gave buyers room to finance a growth story, a turnaround, or a "the seller left money on the table" thesis.

Starting October 1, Initial Acquisitions and Owner Buyouts have to clear 1.25x, measured on either the last fiscal year or the two-year average, on a historical or adjusted basis only. (Business Expansions keep the 1.15x hurdle and can use combined cash flow.) Your projections still get evaluated, but the lender cannot use them to meet the requirement.

In plain terms: the business has to prove it already services the debt, not that it will once you fix it. The turnaround story, the hockey stick, the contract that's about to be signed, none of it counts toward the hurdle anymore.

Some structuring nuance worth knowing: lenders can still make documented adjustments, add-backs for owner compensation, non-recurring expenses, S-corp distributions, and on real-estate deals, the rent the business was paying. But each add-back has to be individually justified in the credit memo, and adjustments to owner comp require a global cash flow analysis showing you can still live on the adjusted salary. Undocumented add-backs simply don't count.

The practical read: underwrite to the trailing numbers with cushion. A deal that clears 1.25x on the weaker of the last year or the two-year average, after a market owner salary is in the expenses, is financeable. A deal that needs the projection to clear isn't financeable yet, and the fix is structural: less bank debt, more seller paper on standby, more equity, or a better price.

Bigger deals now require a Quality of Earnings report

Today, a formal Quality of Earnings report isn't required by the SBA.

Starting October 1, any Initial Acquisition or Business Expansion with a business purchase price of $3 million or more needs one. And the details here trip up almost everyone:

The threshold is measured on the purchase price before your equity, seller note, or any financing, so you can't structure your way under it. The lender orders the QoE, not you, which means the report you commissioned for your own diligence, or the sell-side QoE in the data room, won't satisfy the requirement. And the lender is then required to underwrite coverage on the QoE's normalized earnings figure, not the broker's adjusted EBITDA.

That last part has teeth. If the QoE comes in below the number the deal was priced on, the loan has to shrink, and the gap gets filled with equity or standby money. Sellers with clean, accrual-based books will sail through. Sellers running cash-basis books with heavy personal add-backs are going to feel it.

If you're shopping at $3 million and up, build the QoE cost into your budget and add cushion to your closing timeline, since under delegated lender processing, the valuation and QoE have to be engaged before your loan number is issued. One silver lining: what you spend out of pocket on these reports counts toward your equity injection.

The valuation has to support your full price, on every deal now

Today, on smaller deals (financed amount of $250K or less, net of real estate and equipment), the lender can prepare its own valuation internally.

Starting October 1, that option is gone for acquisitions. Every change of ownership needs an independent valuation from a credentialed Qualified Source, requested by and prepared for the lender.

And the rule with the sharpest edge: the valuation has to support the purchase price regardless of how you structure the debt. If you agree to pay more than the valuation supports, you make up the difference in equity, and any limited-source dollars bridging that gap have to sit on full standby. An appraisal miss now comes out of someone's pocket at the closing table. Pricing discipline on the front end matters more than it ever has.

The streamlined lane for smaller deals is closing

Today, deals of $350,000 or less can move through the lighter-touch 7(a) Small loan process.

Starting October 1, 7(a) Small is no longer available for a change of ownership. Every acquisition, regardless of size, goes through full Standard 7(a) underwriting, including the independent valuation and site visit. If you're buying a smaller business, expect a heavier process than you may have planned for.

If the business comes with its building, the payment math changed

This one has gotten less attention than the equity rules, but for anyone buying a business that includes real estate, it may move the monthly payment the most.

Today, if 51% or more of your loan proceeds go to real estate, the entire loan, goodwill, working capital and all, can ride a 25-year amortization. That's been one of the most powerful levers in the program.

Starting October 1, that shortcut is eliminated. The business portion of the loan caps at a 10-year term, and only the real estate portion can stretch to 25. You either split into two notes (business at 10 years, real estate at up to 25, with 504 available on the property) or run a single blended note on a weighted-average term.

The difference is real money. On a $5M deal where $3M is real estate, today's 51% shortcut puts the whole loan on 25 years. Under the new blend, it lands around 19 years, roughly $45,000 a year more in debt service on an identical deal, and it arrives at the same moment the coverage hurdle rises to 1.25x. The two changes compound. If you're working a real-estate-heavy deal that clears today's 51% test, the October 1 deadline is worth real money to you. If you'll close after, have your lender run both structures, because which one wins depends on the mix and the pricing.

A few things actually loosened

Not everything tightened.

1. The seller can stick around longer. The consulting window doubles from 12 to 24 months. On deals where relationships, licensure, or long sales cycles transfer slowly, that's more runway to learn the business before you're on your own.

2. A new working capital line option. Lenders can now fund part of the purchase tied to working assets onto a line of credit rather than the term loan, useful for distributors, staffing firms, and contractors carrying receivables.

3. Site visits modernized. For online and e-commerce businesses with no physical location, lenders can verify operations virtually instead of requiring a physical visit.

And a couple of things to price for: refinancing a seller note now takes 36 months instead of 24, and seller earnouts remain prohibited (performance-based buyer rebates are still allowed, but the dollars have to pay down the loan principal).

What to do with this

If you're mid-search or structuring a deal right now, the date on your loan number matters. A deal that pencils under today's rules may look different under the new ones, and the reverse is true too. Realistically, plan on 10 to 11 weeks from kickoff to funding if you're trying to close under the current rulebook, before any cushion for the pre-deadline rush.

The through-line across all of it: the new rules reward clean structuring, realistic underwriting, and pricing discipline over optimistic projections. The floor for buying a business is moving up, but SBA financing remains, by a wide margin, the most accessible path to owning a cash-flowing business, with 10% down and 10-year money conventional lenders don't offer. The buyers who navigate this well will be the ones who understand the new framework before they sign an LOI, not after.

If you're working through how these changes affect a specific deal, that's the kind of thing worth talking through with counsel who works in SBA acquisitions every day. We're always glad to help you think it through.
