This will cost you money.
On October 1, 2026, SOP 50 10 8.1 takes effect. It's the SBA's rulebook for 7(a) lending, and the change-of-ownership section got rewritten. If you're buying a business with an SBA loan, the deal you can get approved in September is not the deal you can get approved in October.
Worse, the cutoff isn't when you apply. It's when your loan gets an SBA loan number. A file submitted this month that sits in a lender's queue past September 30 gets underwritten under the new rules.
Here's what changed, and what it costs you.
Where we came from
The October change is the second half of a story.
Before June 2025, SBA acquisition lending was loose. No mandatory minimum equity injection on a change of ownership. Zero-down deals happened. A seller note on interest-only terms could carry most of the equity. Projections could support the coverage math.
Then the numbers caught up. The 7(a) default rate climbed to its highest level in over a decade, SBA purchased roughly $1.6 billion in defaulted loans in FY2024, and the program ran negative cash flow for the first time in about thirteen years.
SBA responded. Fees came back at statutory maximums in March 2025. SOP 50 10 8 landed June 1, 2025 and reinstated pre-2021 underwriting: a hard 10% equity injection, tax transcript verification, the franchise directory, tighter collateral rules, and a drop in the 7(a) Small threshold from $500,000 to $350,000.
Results showed up fast. Through the first nine months of FY2026, 7(a) approvals were down roughly a third by loan count and about a fifth by dollars year over year, and the number of participating lenders fell to a thirty-year low.
That's the environment 8.1 is landing in.
What October 1 actually changes
Five things matter to a buyer.
One. Half your down payment has to be your own cash.
The 10% equity injection stays, and on a first acquisition it can't be reduced or waived at all. What's new is where it comes from. Equity sources are now split into two buckets. Unlimited sources are your unborrowed cash, personal loans repaid from outside the business, and grants. Limited sources are standby debt, a seller note on full standby, and passive minority investor equity, and those combined can supply no more than half of the required injection.
Do the math on a $2.5 million deal. You need $250,000. Under the old rules an investor group or a standby seller note could cover most of it. Now at least $125,000 has to be your money, unborrowed, sitting in an account you can document.
Two. Coverage runs on last year's numbers.
Debt service coverage on an initial acquisition goes to 1.25x, and it has to be supported by historical or documented trailing earnings. A lender can look at your forecast, but the forecast can't carry the test.
That's roughly nine percent more trailing cash flow than the old 1.15x standard, and it removes the growth story as a financing argument. A business you were going to buy on what it's about to do now has to qualify on what it already did.
Three. Every deal gets an independent valuation. Big ones get a Quality of Earnings report.
The shortcut where a lender could run its own internal valuation on smaller deals is gone. Every change of ownership requires an independent third-party valuation from a qualified source, engaged by the lender.
On top of that, at a purchase price of $3 million or more, the lender has to commission a Quality of Earnings report. It reconciles bank activity against the income statement and tax returns, documents add-backs, and looks at customer concentration. The lender then has to use those normalized earnings in the coverage math. If the QoE doesn't support the seller's numbers, the loan shrinks or your equity grows.
Both cost money and take time. Budget for both.
Four. Small deals lost the fast lane.
7(a) Small and streamlined underwriting are no longer available for a change of ownership at any size. A $300,000 acquisition now goes through full standard underwriting with a formal independent valuation, same as a $4 million one.
Five. Seller paper got stickier.
Seller notes still count toward equity on full standby, inside that 50% ceiling. But a seller note created in an SBA-financed acquisition now has to season 36 months before it can be refinanced, up from 24. And the window where a seller can stay on as a consultant after a full acquisition extends from 12 months to 24.
The eligibility gate nobody plans for
Separate from all of this, and easy to trip over.
As of March 1, 2026, SBA requires that 100% of all direct and indirect owners be U.S. citizens or U.S. Nationals with a principal residence in the U.S. Lawful permanent residents, including unconditional green card holders, are excluded. There's a six-month lookback on ownership before the loan number is issued.
This rule has moved three times in a year and it's been challenged. In July 2026 the GAO concluded the notices implementing it qualified as rules under the Congressional Review Act and should have been submitted to Congress first. As of this writing the standard still appears to be in force.
Whatever happens to it, the practical point stands. Confirm the citizenship status of every owner and required guarantor before you sign an LOI. A deal can be perfect and non-financeable.
What to do about it
If you have a live deal, call your lender this week and ask one question: will this file receive an SBA loan number before September 30. Not "will you submit it." Will it get a number.
If you're earlier than that, plan on the new math. More cash from you, a valuation that has to hold, coverage that comes from history, and a longer, more documented process.
There's an upside worth naming. Underwriting that runs on trailing earnings rewards businesses that already work. Established companies with clean books and thirty years of history finance more easily than growth stories. That's exactly the profile you find off-market, talking to an owner who's been at it since the eighties and never listed anything.
The financing got harder. The businesses that clear it were always the ones worth owning.
