Using an SBA 7(a) Loan to Buy a Business: 2026 Rules, Equity Injection, Seller Notes, and DSCR

The SBA 7(a) loan is the standard way an individual buyer finances a small business acquisition in the United States. A bank lends up to $5 million, the federal government guarantees most of it, and a buyer with roughly 10% of the purchase price in cash can close on a company doing seven figures in revenue. That's the pitch, and it's real. But the rules underneath it changed on June 1, 2025, and they change again on October 1, 2026. If you're planning an acquisition right now, you're planning it across that line.

This guide covers the rules as they stand in August 2026, what the October revision does to them, and how the seller's own SBA loan (the one they took out years ago) is often the reason the deal is available at all.

The basics: how much, how long, at what rate

The 7(a) program caps at $5 million per borrower. The SBA guarantees up to 85% of loans of $150,000 or less and up to 75% of loans above $150,000, which is why banks will underwrite a first-time buyer with no operating history in the industry. The guarantee absorbs most of the bank's downside.

Maturities depend on what the money buys. Real estate can run up to 25 years. Everything else, including the goodwill in a business acquisition, is capped at 10 years or less. Under the SOP taking effect October 1, 2026, the business acquisition portion of any 7(a) loan is capped at a 10-year amortization with no balloon. A real estate portion can still run to 25 years, and the blended term is set on a weighted average, per Accredited's summary of the new SOP.

Variable interest rates are capped by loan size on the SBA's published schedule: base rate plus 6.5% for loans of $50,000 or less, plus 6.0% up to $250,000, plus 4.5% up to $350,000, and plus 3.0% above that. Most acquisition loans land in the last bracket. With prime as the base rate, that top bracket is what a typical buyer pays.

To be eligible at all, the target must be an operating for-profit business located in the U.S., small under SBA size standards, and creditworthy, and you must be unable to get the same credit on reasonable terms from non-government sources. Those requirements come straight from the program rules.

The equity injection: where your 10% comes from

Every complete change of ownership requires a minimum equity injection of 10% of total project costs. Total project costs means everything: purchase price, working capital, fees, all of it, regardless of where the funds come from. The current rulebook is SOP 50 10 8, effective for loans numbered on or after June 1, 2025.

What counts as injection is narrower than most first-time buyers expect. Per Starfield & Smith's review of the SOP 50 10 8 injection rules, acceptable sources are unborrowed cash, cash from a personal loan with an outside source of repayment, debt on full standby for the life of the SBA loan, grants with no repayment obligation, non-cash assets with proper valuation, and verified prepaid expenses. Lenders have to verify the money actually moved. That means account statements showing the funds sat in your account for at least 30 days, copies of wires or checks, and settlement statements. A gift letter or a promissory note by itself doesn't satisfy the requirement.

On a $1.5 million deal with $100,000 of working capital and fees, project costs are $1.6 million and your injection is $160,000. Plan for more than the minimum. Lenders like post-close liquidity, and the buyers who get approved fastest show up with it.

Seller notes: the 5% that changes the math

A seller note can fund part of your injection, and that is the piece of structure worth understanding before you make an offer. The conditions are strict. The note must be on full standby for the entire life of the SBA loan, so the seller receives no principal and no interest for ten years, which is what the signed SBA Form 155 commits them to. And it can cover at most half of the required injection. On a 10% requirement, that's 5% from the seller and 5% minimum from you in cash.

So the $1.6 million deal above can close with $80,000 of your cash and an $80,000 full-standby seller note. Sellers agree to this more often than you'd guess, because the note signals confidence in the business they're handing you, and because the alternative is a lower price. Partial standby earns no injection credit at all, and neither does a note that pays current interest. Those notes still fit in the capital stack. They sit on the debt side of it.

From October 1, 2026 the rules tighten further: the waiting period before a seller note can be refinanced goes from 24 to 36 months, and total transaction debt including any non-standby seller note is capped at the supported business valuation. Premiums above the appraisal have to be paid in cash or carried as full-standby seller debt.

DSCR: the number that approves or kills the deal

Debt service coverage ratio is the business's annual cash flow divided by its annual debt payments. Under the current SOP, lenders can still use projections to get an acquisition across the line. That door closes in October.

SOP 50 10 8.1, issued August 14, 2026 and effective for loans that receive an SBA loan number on or after October 1, 2026, sets a 1.25x DSCR floor for initial acquisitions and owner buyouts, keeps 1.15x for business expansions, and requires the coverage to be met on historical or adjusted historical earnings from the last fiscal year or the average of the last two. Post-closing projections no longer satisfy the test. The same SOP requires an independent quality of earnings report on initial acquisitions and expansions where the purchase price is $3 million or more, excluding owner-occupied real estate. The lender has to obtain it, and it cannot be prepared by or for the buyer or the seller. Small-loan scorecard underwriting is gone for changes of ownership entirely.

The practical translation: a business with $500,000 of adjusted annual earnings supports about $400,000 of annual debt service at 1.25x. Prime sat at 6.75% in the Federal Reserve's H.15 release this month, so the top bracket caps out at 9.75%. Amortize $400,000 a year over ten years at that rate and you get roughly $2.55 million of debt. Work the math backward from earnings and you know your ceiling before you ever talk to a lender. Scouly's deal benchmark tool runs the other direction: it puts a loan or an asking price against the actual SBA lending distribution for the vertical and state you're searching.

Personal guarantees and who can borrow

Every SBA loan must be guaranteed by at least one person or entity under 13 CFR 120.160, and in practice anyone owning 20% or more of the borrower must provide an unconditional personal guarantee. It's unlimited and lenders can't waive it. If the seller keeps any equity stake after closing, even 1%, SOP 50 10 8 requires them to personally guarantee the loan for at least two years, which pushes buyers toward a clean 100% buyout.

Citizenship rules also changed this year. Effective March 1, 2026, SBA policy requires 100% of a small business applicant's direct and indirect owners to be U.S. citizens or U.S. nationals with their principal residence in the United States, its territories, or its possessions. The same notice rescinded the old 5% carve-out, and lawful permanent residents can no longer own any percentage of an SBA borrower. If your cap table includes a green card holder or any foreign investor, the 7(a) is off the table until that changes.

Two SBA loans in every deal

Most financing guides stop at the loan you're applying for. That one is the second SBA loan in the deal. The first is the one the seller took out ten or fifteen years ago to buy the building or the business itself. That loan is public record in the SBA's 7(a) and 504 FOIA files, and its maturity date is a timing signal.

An owner whose loan is reaching payoff is at a decision point. The debt that anchored them to the business is ending, the balance sheet clears, and the retirement conversation gets real. Scouly tracks 66,307 companies with a dated SBA loan across 51 state pages, and 7,892 of those loans mature between 2026 and 2028. That cohort is the maturity wall, and reading it owner by owner is the whole method behind using SBA loan data as an acquisition signal.

The two loans connect. The seller's maturing loan tells you when to write the letter. Your 7(a) is how you fund what comes after the reply. And because the FOIA record shows what a bank lent against the business at underwriting, it also grounds your price expectations before diligence starts.

If you're still deciding where to hunt, define an acquisition thesis first: one industry and one geography, sized to what your equity injection can actually cover. Then work the maturity data inside it.

Frequently asked questions

How much can I borrow with an SBA 7(a) loan to buy a business? The program maximum is $5 million. The SBA guarantees up to 85% of loans of $150,000 or less and up to 75% above that, which is what makes banks willing to lend to first-time buyers. Your real ceiling is set lower by cash flow: the target's earnings must cover debt service with room to spare.

How much money down do I need for an SBA business acquisition? A complete change of ownership requires a minimum equity injection of 10% of total project costs, which includes the purchase price plus working capital and fees. Half of that can come from a seller note on full standby, so your personal cash minimum is 5%. Lenders verify the funds with 30 days of account statements.

Can a seller note count toward my SBA equity injection? Yes, up to half of the required injection, and only if it's on full standby for the entire life of the SBA loan, meaning the seller receives no principal or interest payments, documented on SBA Form 155. A note that pays current interest is allowed in the deal but counts as debt, and after October 1, 2026 it counts against a valuation-based cap on total transaction debt.

What DSCR do SBA lenders require in 2026? For loans numbered on or after October 1, 2026, SOP 50 10 8.1 sets a 1.25x minimum debt service coverage ratio for initial acquisitions and owner buyouts, measured on historical or adjusted historical earnings only. Business expansions keep a 1.15x floor. Projections no longer count, so the business has to cover the debt on what it already earns.

Do I have to personally guarantee an SBA 7(a) loan? Yes. Federal regulation requires at least one personal guarantee on every SBA loan, and anyone owning 20% or more of the buying entity must sign an unlimited, unconditional guarantee. Lenders cannot waive or cap it. A seller who retains any ownership stake after closing must also guarantee the loan for at least two years.

Can a green card holder get an SBA loan to buy a business? Not as an owner under current policy. Effective March 1, 2026, SBA requires 100% of a small business applicant's direct and indirect owners to be U.S. citizens or U.S. nationals with their principal residence in the United States, its territories, or its possessions. Lawful permanent residents are no longer eligible to own any percentage of the borrowing entity.
