SBA Underwriting Standards Are Tightening: A Return to Pre-Biden Lending Rules or a New Era of Credit Discipline?

The U.S. Small Business Administration (SBA) has moved to strengthen underwriting standards, citing defaults, credit risk, and the financial sustainability of its flagship 7(a) loan program as reasons for the 2025 policy reversal. The changes represent a partial reversal of policies adopted during the Biden administration, but they also introduce new requirements that go beyond simply restoring the previous rulebook.

For banks, Certified Development Companies (CDCs), business acquisition lenders, commercial real estate developers, and borrowers seeking SBA financing, the practical implications are significant. Lenders must pay close attention to repayment capacity, historical financial performance, business valuations, transaction structure, eligibility, and the quality of supporting documentation.

The changes also raise an important question: when a lender must demonstrate that a business can repay its debt, how can it distinguish a genuinely viable investment from a transaction supported by overly optimistic assumptions?

Independent feasibility studies, market research, financial modeling, and investment due diligence can help answer that question. Although a feasibility study is not automatically required for every SBA loan, rigorous independent analysis can be especially valuable when a transaction involves a startup, an acquisition, a new facility, an expansion, or an uncertain market.

1. Did the SBA Reverse Biden-Era Underwriting Standards?

The short answer is partly yes, but the current changes are more than a simple reversal of prior policy.

On April 22, 2025, the SBA announced that it was eliminating what it characterized as weakened underwriting standards introduced during the previous administration. The agency specifically identified the “Do What You Do” underwriting framework, reduced lender fees, and changes to franchise eligibility procedures as areas requiring correction.

The SBA's position was that these policies weakened longstanding credit safeguards and contributed to higher defaults and losses in the 7(a) program. It announced the restoration of more prescriptive lending criteria through SOP 50 10 8. The policy became effective June 1, 2025, with subsequent amendments and technical updates.

What changed under the previous administration?

A significant policy change occurred when the SBA adopted a more flexible underwriting framework that allowed participating lenders to rely more heavily on their own established credit policies instead of following certain standardized SBA-specific underwriting procedures.

The 2023 rule described an access-to-capital and modernization objective. It required appropriate and prudent commercial credit processes consistent with similarly sized non-SBA commercial loans. Importantly, it retained the requirement that an applicant be creditworthy and the loan sufficiently sound to reasonably assure repayment. It did not abolish credit analysis. See the April 10, 2023 Federal Register final rule, effective May 11, 2023.

The Biden-era policy changes also included reductions or eliminations of certain lender fees, affecting the program's revenue available to offset credit losses.

In its April 22, 2025 announcement, SBA reported approximately $397 million of negative 7(a) program cash flow for fiscal year 2024. That is the agency's reported program cash-flow figure—not a default rate, a realized loss on every loan cohort, or a forecast of every future taxpayer cost. The announcement's causal and political characterizations should be attributed to SBA, not treated as an independent causal study.

Why defaults increased

SBA-backed loan performance can be influenced by several factors operating simultaneously:

• Underwriting standards: Less prescriptive requirements can increase the risk that borrowers with marginal repayment capacity receive financing.
• Interest rates: Higher borrowing costs and tighter financial conditions can reduce cash flow and debt-service coverage.
• Operating expenses: Wage increases, insurance costs, rent, utilities, and other expenses can erode margins.
• Business projections: Borrowers may fail to achieve projected revenue, pricing, occupancy, customer acquisition, or operating efficiency.
• Acquisition pricing: Buyers who pay too much for a business can inherit insufficient cash flow to service acquisition debt.
• Lender practices: Differences in screening, financial verification, risk tolerance, and portfolio monitoring affect outcomes.

To evaluate performance, lenders should distinguish approvals, outstanding balances, delinquencies, defaults, guarantee purchases, recoveries, and program cash flow. Comparisons should use consistent origination cohorts and observation periods. This article does not estimate how much of any observed deterioration was caused by a particular administration's policies.

The appropriate conclusion is that the policy reversal responds to documented credit and financial concerns, but the relative contribution of underwriting changes, economic conditions, lender behavior, and borrower performance should not be reduced to a single cause.

2. The Three Main Stages of SBA Underwriting Policy

Understanding the timeline is essential because a loan originated under one version of the SBA's rules should not automatically be evaluated using a later version.

Official references:

• SBA SOP 50 10 document index and current download
• 2023 final rule on affiliation and lending criteria
• Congressional Research Service: April 28, 2025 explanation of the 2025 changes (historical analysis)
• SOP 50 10 8 technical updates
• SOP 50 10 8.1 technical updates, effective October 1, 2026

The important distinction is that the 2025 changes largely restored a more prescriptive approach, while the 2026 edition adds further detail and differentiated treatment for particular transactions. The September 25, 2026 technical notice applies the updated SOP to applications received by SBA on or after October 1, 2026, and instructs lenders to continue using SOP 8 for applications submitted through September 30. A borrower's first contact with a bank is not the same event. The earlier August issuance notice used different loan-number wording; use the later notice and obtain lender/SBA clarification for transition edge cases.

The current official index, last updated October 7, 2026 when checked for this article, links to an October-directory DOCX. The directory and index-update dates are not a new effective date. The governing edition still states October 1, 2026. The chronology above is selective, not a complete register of every interim procedural notice.

3. What Are the New SBA Underwriting Standards?

SOP 50 10 governs the origination policies and procedures for the SBA 7(a) and 504 loan programs. The exact requirements depend on the loan program, transaction type, financing amount, and applicable policy edition.

Several areas deserve particular attention.

A. Greater emphasis on documented repayment capacity

An SBA guarantee does not eliminate the need to determine whether a borrower can repay a loan. The lender must evaluate the business's ability to support its debt obligations and document the basis for its credit decision.

This includes reviewing historical financial statements, tax returns, existing debt, proposed debt service, operating expenses, working capital requirements, and other relevant financial information.

For a business acquisition, the lender must also consider the cash flow available after the transaction closes, including the effect of acquisition financing and other continuing obligations.

The key issue is not whether a business plan describes an attractive opportunity. It is whether the supporting financial evidence demonstrates a credible ability to service the proposed debt.

B. More transaction-specific acquisition underwriting

SOP 50 10 8.1 introduces a more differentiated approach to changes of ownership through Appendix 15. Initial acquisitions, business expansions, owner buyouts, and other ownership transactions should not automatically be treated as identical credit situations.

This is important because an acquisition may depend on the earnings of an existing business, while a new facility or expansion may depend more heavily on future operating performance.

Under the applicable 2026 provisions, lenders must identify the transaction category and apply the corresponding repayment, valuation, and documentation requirements. The relevant provisions may differ from the general standards used for other 7(a) loans.

C. Historical performance versus projected performance

Financial projections remain important, but lenders must distinguish between historical cash flow and assumptions about future growth.

For an acquisition, historical earnings can provide evidence of established demand, margins, and operating performance. Projections can then explain anticipated changes, such as cost savings, expanded capacity, new products, or additional locations.

However, projections should not be used to conceal weak historical performance or justify an acquisition price unsupported by the business's economics. Where the applicable acquisition rules prescribe how repayment coverage must be established, those requirements control.

D. Business valuations and quality-of-earnings analysis

Business valuations and quality-of-earnings reviews address different risks.

A valuation examines the reasonableness of the price paid for a business or the value of the business interest being acquired. A quality-of-earnings review examines the reliability, sustainability, and composition of reported earnings.

Under Appendix 15, Business Expansion and Initial Acquisition transactions with a defined Business Purchase Price of $3 million or more generally require a Quality of Earnings (QoE) report in addition to the required business valuation. Apply the threshold before buyer equity, seller debt, or other financing sources. Owner Buyout and ESOP/Cooperative categories have exceptions, and qualifying owner-occupied Special Purpose Property transactions have separate treatment. An owner-buyout label alone is not sufficient: a transaction that fails that category's conditions can be subject to Initial Acquisition credit standards.

The threshold must be evaluated using the prescribed Business Purchase Price calculation, not simply total project cost or the amount borrowed. The definition excludes acquired owner-occupied commercial real estate. Appendix 15's internal-valuation provision uses a $350,000 Business Purchase Price threshold and a close-relationship exception; it is not a general exemption from independent review. See the current SOP, Appendix 15, definitions and credit standards.

Do not assume an already commissioned QoE report is automatically acceptable. The technical notice mentions a reliance letter or secondary review, while the inspected current SOP text requires a review by a lender-approved vendor before reliance on another party's report. Neither allows a seller-prepared or seller-commissioned report. Obtain lender/SBA clarification rather than choosing the less restrictive wording. Feasibility work does not replace this requirement.

For lenders, these reviews can help identify:

• Earnings that are not supported by tax returns or financial statements.
• Unusual or nonrecurring adjustments to EBITDA.
• Revenue concentration or customer dependence.
• Unrecorded liabilities and unusual expenses.
• Working capital shortfalls.
• Acquisition prices that exceed the business's demonstrated earning capacity.

A feasibility study is not a substitute for a required independent valuation or quality-of-earnings report. Each serves a different purpose.

E. Verification and documentation

Lenders should not treat borrower representations, financial projections, or third-party reports as interchangeable forms of evidence.

Financial information must be reviewed and verified as required by the applicable SBA procedures. The lender should retain the analysis and supporting documentation necessary to explain the credit decision.

For complex projects, this may involve reconciling financial statements, tax returns, bank records, operating assumptions, market data, construction budgets, and proposed financing terms.

The level and type of verification required depend on the transaction and governing SBA rules.

4. Why the October 2026 Changes Matter for Business Acquisitions

Business acquisitions deserve special attention because the buyer is assuming an existing operation while adding new debt obligations.

An established business may have a long operating history and recognizable customers but still be a poor acquisition if the buyer pays too much, underestimates expenses, or relies on earnings that cannot be sustained.

The October 1, 2026, SOP 50 10 8.1 changes make it especially important to distinguish acquisition categories and review the applicable Appendix 15 requirements.

Lenders should examine the following:

Historical cash flow. Are reported earnings supported by the business's financial records and tax returns? Are adjustments to earnings reasonable and documented?

Debt-service coverage. Does the business generate sufficient cash flow to meet the debt-service requirement applicable to the transaction?

Purchase price. Is the proposed price supported by the business's earnings, assets, market position, and appropriate valuation analysis?

Working capital. Will the business have enough liquidity to operate after closing, including during seasonal fluctuations or unexpected expenses?

Transition risk. Will customer relationships, supplier agreements, licenses, management capabilities, or other critical operating factors change when ownership transfers?

Growth assumptions. Are anticipated improvements supported by credible evidence, or do they depend on untested assumptions?

A business acquisition should be assessed as an investment, not simply as a financing transaction.

5. What the Changes Mean for SBA 504 Real Estate Financing

The SBA 504 program is designed to support eligible small businesses acquiring or improving qualifying fixed assets. It is often used for owner-occupied commercial real estate, equipment, and other eligible long-term investments.

The credit analysis must consider both the business's operating capacity and the proposed project's economics.

For a commercial real estate project, key considerations include the purchase price or construction cost, eligible project expenses, financing structure, occupancy and operating requirements, and the borrower's ability to support the debt.

For a new facility or expansion, the analysis may also need to address:

• Local market demand for the business's products or services.
• The adequacy of the proposed site and facility.
• Construction and development costs.
• Permitting, zoning, and implementation risks.
• Staffing, equipment, and operating requirements.
• Revenue assumptions and expected operating margins.
• Cash flow under less favorable market conditions.

The September 25 technical notice makes two concrete 504 distinctions: a Third Party Lender (TPL) may submit its underwriting analysis directly to the Sacramento Loan Processing Center (SLPC), and the notice removes the prohibition on the TPL loan's amortization exceeding the 504 debenture term. The notice says a direct-upload feature would be available in the future; it does not prove that feature is currently operating. These are not the same as Appendix 15's 7(a) acquisition rules.

Section C's feasibility-study provisions say the SLPC Director will request a study when appropriate to understand the business type and local market conditions. The listed possible triggers are market saturation; a unique market concept; highly specialized project property; project size disproportionate to the community served; and rapid applicant or affiliate growth accompanied by increased undisbursed or unseasoned debt. These are possible triggers, not an automatic study mandate for every 504 loan. A lender may also request independent analysis under its own credit policy.

6. Have SBA Feasibility Study Requirements Changed?

This is an important distinction for borrowers, lenders, and feasibility-study consultants.

There is no universal SBA rule requiring a formal feasibility study for every 7(a) or 504 loan. The need for a study depends on the project, the applicable SBA requirements, and the lender's credit and documentation standards.

A feasibility study is also not a replacement for the lender's responsibility to underwrite a loan.

Nevertheless, the renewed focus on documented repayment capacity and transaction-specific analysis can increase the practical importance of independent feasibility studies.

What a lender needs from a feasibility study

A professionally prepared study can help determine whether a proposed business or project is economically viable and whether the assumptions underlying the financing request are credible.

A well-supported study may examine six principal areas.

1. Market feasibility. This evaluates the market's size, customer demand, competition, pricing, market penetration assumptions, and the business's likely position relative to competing businesses.

2. Economic feasibility. This examines demographic and economic conditions, employment, population trends, industry activity, and other external factors affecting demand.

3. Technical and operational feasibility. This evaluates the suitability of the proposed site, facility, equipment, production capacity, staffing, operating model, and implementation plan.

4. Financial feasibility. This tests projected revenue, expenses, operating margins, working capital, capital expenditures, debt service, and cash flow available for repayment.

5. Management feasibility. This examines the experience and capabilities of the management team, staffing needs, operating responsibilities, and the ability to execute the business plan.

6. Risk and sensitivity analysis. This evaluates how changes in sales, pricing, costs, occupancy, construction expenses, interest rates, or opening dates could affect financial performance and repayment capacity. A study can examine supplied technical reports; engineering, environmental, legal and tax conclusions require appropriately qualified specialists.

Not every assignment requires the same scope. A mature operating business seeking a modest equipment loan may need a different analysis from a startup, a major acquisition, a new hotel, or a manufacturing facility requiring substantial capital investment.

What has changed in practice?

The most important change is the underwriting environment rather than a blanket new mandate for feasibility studies.

When lenders have greater responsibility to substantiate their credit decisions, they may seek stronger independent evidence supporting projected performance and market demand.

A borrower may present a business plan with attractive projected revenue. A lender, however, needs to understand whether the proposed location can support the business, whether the market is large enough, whether competitors constrain pricing, and whether the projected margins are achievable.

An independent feasibility study can help test those assumptions before the lender commits capital.

For new construction and expansion projects, the study can also help determine whether the proposed investment is appropriately sized for the market. An oversized facility, excessive construction budget, or unrealistic ramp-up period can undermine repayment even when the underlying business concept is sound.

For acquisitions, feasibility analysis can complement the financial review by evaluating market conditions, competitive positioning, operating risks, and the credibility of the buyer's business plan.

What a feasibility study does not do

A feasibility study does not guarantee loan approval, replace required financial verification, substitute for a required business valuation or quality-of-earnings review, or establish that a loan satisfies every SBA eligibility requirement.

Nor should a lender assume that a report is compliant merely because it is labeled an “SBA feasibility study.”

The report must address the actual assignment, use credible evidence, explain its methodology, and provide conclusions that are supported by the analysis. Any formal SBA requirement or lender-specific reporting instruction must be evaluated separately.

7. How Wert-Berater Can Help SBA Lenders Manage Underwriting Risk

Wert-Berater provides independent market intelligence, feasibility analysis, financial modeling, underwriting support, and investment due diligence for lenders, investors, developers, and business owners.

Since 1998, the firm has worked on feasibility and investment-analysis assignments across multiple industries and project types.

For SBA lenders, the objective is to provide independent analysis that helps clarify the commercial and financial assumptions behind a proposed loan.

Depending on the assignment, Wert-Berater can assist with:

• Market demand analysis: Evaluating local market conditions, customer demand, competition, and revenue potential.
• Business and project feasibility: Assessing whether a proposed startup, acquisition, expansion, or development project is economically supportable.
• Financial modeling: Examining revenue, expenses, cash flow, capital requirements, debt service, and downside scenarios.
• Real estate feasibility: Evaluating market support for owner-occupied operating facilities, hotels, industrial properties, and other projects after program eligibility has been confirmed. The firm's broader real estate services do not make passive rental or multifamily investment eligible for SBA financing.
• Expansion and new-construction analysis: Testing whether a proposed facility, production capacity, or development budget is consistent with market demand.
• Investment due diligence: Identifying assumptions and risks that deserve further examination before a financing decision is made.

The scope should be tailored to the lender's needs and the project's specific risks. The resulting report can support the lender's independent credit analysis without replacing the lender's underwriting responsibilities.

8. What SBA Lenders Should Do Now

Banks and CDCs should review the current SOP, applicable technical updates, and their internal underwriting procedures before processing new transactions.

They should identify which policy version applies to each file, particularly when an application spans an effective-date transition.

Lenders should also review whether their documentation adequately supports the proposed repayment structure, financial assumptions, transaction valuation, and project feasibility.

For higher-risk or less conventional projects, independent analysis should be considered early enough to identify material problems before the borrower incurs substantial acquisition, design, or development costs.

Borrowers, meanwhile, should be prepared to explain the commercial rationale for the project, support their financial assumptions, document management capabilities, and demonstrate how the business will generate enough cash flow to meet its obligations.

The purpose is not to make SBA financing inaccessible. It is to improve the quality of credit decisions and reduce the likelihood that borrowers take on debt their businesses cannot support.

9. Conclusion: Stronger Underwriting Makes Independent Analysis More Valuable

The SBA's move toward more prescriptive underwriting reflects concerns about defaults, credit risk, and the financial performance of its loan programs. The 2025 policy changes restored important elements of the earlier framework, while SOP 50 10 8.1 introduced additional transaction-specific requirements effective October 1, 2026.

These changes should not be interpreted as a universal requirement for feasibility studies. Instead, they reinforce the importance of credible financial information, documented repayment capacity, appropriate valuation, and evidence supporting a project's economic assumptions.

For lenders, a disciplined underwriting process begins with understanding the transaction and testing the assumptions that drive repayment. For borrowers, it means preparing a realistic business case supported by evidence rather than relying solely on optimistic projections.

Independent feasibility studies can help bridge that gap by evaluating market demand, operating requirements, financial performance, and investment risk before a financing decision is made.

10. Compare the Policy Frameworks Without Mixing Their Rules

The comparison below separates the historical framework from today's file-level decision. It is a practical reading guide, not a substitute for the complete SOP and subsequent notices.

The 2023 final rule and the Congressional Research Service's April 2025 analysis support the historical columns. The current SOP and September 2026 notice support the current column. A tighter lender overlay is not automatically a new SBA rule.

11. Which Report Answers Which Underwriting Question?

A lender should specify the report type, intended users, independence, reliance arrangements, valuation date or research date, and required scope before commissioning work. An attractive report title does not establish compliance.

For the detailed coverage ratios, definitions and analytical examples, use the firm's existing SBA SOP 50 10 8.1 technical guide. For service scope and commissioning, see SBA feasibility study services, SBA 7(a) feasibility study guidance, and SBA 504 feasibility study guidance.

12. When and How to Order Independent Analysis

Engage early enough to change the decision. For acquisitions, begin once the transaction structure, financial records and proposed financing are sufficiently defined. For construction or expansion, allow analysis before irreversible acquisition, design or development commitments. A study completed only after major commitments may identify risks too late to change the project economically.

1. Confirm the program, transaction category and governing edition with the lender or CDC.
2. Ask which reports are required by SBA, which are requested by the lender, and who must commission each one.
3. Define the site, business model, purchase or development budget, financing assumptions, market area, available records and intended decision.
4. Agree the scope, data needs, intended users, independence requirements, fee and achievable delivery date in writing.
5. Transfer confidential records only through the agreed secure channel—not a public inquiry form.
6. Reconcile the completed analysis with the credit file, resolve exceptions, and update material assumptions before closing.
