SBA underwriting guidelines: the rules, approval rates and credit history

Published October 25, 2026 · Rules checked against SBA and IRS sources as of October 2026

Knowing what the underwriter has to write down tells you what to prepare. Under SOP 50 10 8.1, the lender's credit memo for a change of ownership must address a specific list. Here it is, translated.

1. The business and its management

• Description of the business, its history, industry and management structure.
• Your industry experience and management team, and how day-to-day operations will run if you're not on site daily.
• Any management agreement (other than one in a Franchise Directory brand's disclosure documents), reviewed for passive-business risk.

2. Repayment ability

3. Collateral and insurance

Collateral adequacy using SBA's fully secured haircuts; life insurance on whom and how much (or why not); hazard and liability insurance.

4. Everything else the memo must discuss

• Why credit isn't available elsewhere on reasonable terms.
• Why working capital is needed, if it's 50% or more of proceeds.
• Competition.
• 90+ day delinquencies and trade disputes.
• Government citations that could stop operations.
• Liens, judgments, bankruptcy filings and pending litigation, including divorce.
• For franchises: franchisor information such as failed franchisees and projections.
• Refinancing of any debt, with late payments in the last 12 months explained.
• The valuation and how it supports the price.

What this means for you

Each item is a question you can answer before it's asked. Write a two-page memo of your own covering management, the numbers, adjustments with evidence, working capital and anything awkward in your credit history. Lenders notice buyers who do that. Credit officers: see the change-of-ownership credit memo checklist.

Approval rates

SBA doesn't publish an approval rate for 7(a) acquisition loans that we could verify, and most declines happen at lenders before an application ever reaches SBA, so any rate you see quoted is an estimate. What is clear from SOP 50 10 8.1 is where acquisition deals fail: historical cash flow below 1.25x, a valuation below the price, unverifiable seller numbers, thin buyer experience, not enough equity or liquidity, and ineligible owners.

A rate wouldn't help you much anyway: what matters is whether your deal clears the specific tests. Here are the common failure points, in roughly the order lenders find them.

The usual reasons

Use the affordability calculator on the tax-return numbers, not the listing's, and read how lenders underwrite.

Prior bankruptcy

A past bankruptcy doesn't automatically make you ineligible for an SBA 7(a) loan under SOP 50 10 8.1, but the lender's credit memo must discuss any bankruptcy filings, and lenders weigh them under their own credit policy. The harder line is federal: a prior loss to the government or delinquent federal debt must be resolved, though federal debt you were discharged from (or are subject to) in bankruptcy, with any court-authorized plan current, isn't treated as delinquent.

Plenty of successful operators have a bankruptcy in their past. For an SBA acquisition, it's a credit question, not usually an eligibility one.

What the SOP says

• Credit memo: must discuss liens, judgments, bankruptcy filings and pending litigation.
• Prior loss to the government: an applicant (or certain associates) with a prior federal loss is affected unless the loss has been fully satisfied.
• Delinquent federal debt: must be resolved; the SOP says a debt isn't delinquent if the obligor is subject to or discharged from it in bankruptcy and current on any court-authorized repayment plan.
• Express: the lender's judgment decides how much a past bankruptcy weighs.

How to make the case

1. Write a one-page explanation: what happened, what you learned, what's different now.
2. Show clean credit since discharge.
3. Bring more equity or post-closing liquidity than the minimum.
4. Pick a deal with strong historical coverage, so the decision isn't close.
5. Ask lenders their policy before a hard credit pull.

If a prior SBA loan was involved in the bankruptcy, raise it with the lender immediately; it may be an eligibility issue rather than a judgment call. See credit score expectations.

The rule set in one place

SBA 7(a) rules come in layers: the Small Business Act (the statute), SBA's regulations in 13 CFR Part 120, the Standard Operating Procedure SOP 50 10 (currently 8.1 with technical updates, effective October 1, 2026), and policy and procedural notices that amend it. Lenders work from the SOP day to day. For business purchases, the rules are in Appendix 15, which overrides anything else in the SOP that conflicts.

If you're relying on an SBA rule for a decision, it's worth knowing where to look it up. Here's the hierarchy and a practical way to check things.

The layers

What's in each

• The Act sets the program and a few hard rules (for example, the statutory full guarantee from an ESOP seller who keeps a stake).
• 13 CFR Part 120 covers eligibility, uses of proceeds, guarantees, fees and maturities. Searchable on eCFR.
• SOP 50 10 8.1 is the lender's manual. Appendix 15 holds all change-of-ownership rules; Appendices 14, 16-20 cover refinancing, guaranty amounts, maturities, rates, collateral and submission.
• Notices fill gaps between SOP versions. SOP 50 10 8.1 integrated several 2025-2026 notices, including the citizenship policy effective March 1, 2026.

How to check a rule

1. Download the current SOP from SBA's SOP 50 10 page and search the PDF or Word file for the term.
2. For acquisitions, start in Appendix 15; it governs if anything conflicts.
3. Check the effective date of what you're reading against your loan number date.
4. Look for notices issued after the SOP's effective date.
5. Ask your lender how it applies the rule; its policy may be stricter.

A live example of why this matters

The August 14, 2026 issuance of SOP 50 10 8.1 had no in-house valuation option, and many summaries said every change of ownership needs an independent valuation. The version with technical updates that SBA posted for October 1, 2026 allows the lender to value a business itself when the Business Purchase Price is $350,000 or less and buyer and seller aren't closely related. Same SOP number, different rule. See the $350,000 valuation option.
