SBA Loan Programs for Buying a Business: 7(a), 504, Express, and Which One You Need (2026)

Most first-time buyers know "the SBA" as a single thing. It's not. The Small Business Administration runs a family of loan programs, each built for a different use case, each with different caps, different underwriting standards, and different terms. Choosing the wrong program — or letting a lender default you into a program because that's the only one they offer — costs real money over the life of the loan and sometimes determines whether the deal happens at all.

This post walks through the five programs that matter for buyers of small operating businesses, when each one is the right fit, and how they combine on more complex deals.

The Five SBA Programs at a Glance

A sixth program — Community Advantage, a 7(a) variant capped at $350,000 for under-served markets — exists but is narrow enough that it falls outside the typical acquisition decision.

SBA 7(a): The Default Program for Buying a Business

The 7(a) loan is the SBA's flagship program and the right answer for most operating-business acquisitions. Understanding why means understanding what 7(a) can fund that no other SBA program can.

What 7(a) Can Fund

A single 7(a) loan can finance:

• Goodwill — the premium over book value that is most of what you're paying for in a small business acquisition. This is the line item that disqualifies 504 from being the primary acquisition loan.
• Working capital — operating cash to run the business post-close. 504 cannot do this.
• Equipment and FF&E — vehicles, machinery, tools, computers, furniture.
• Inventory — both opening inventory and ongoing inventory needs.
• Owner-occupied real estate — buildings the business operates from (at least 51% borrower-occupied). 504 is often better for the real estate piece specifically, but 7(a) can handle it.
• Refinancing of existing business debt (with restrictions — see SOP 50 10 8 for the qualifying tests).
• Closing costs and fees — the SBA guaranty fee, loan packaging fees, third-party reports.

Maximum Loan Size and Terms

• Maximum loan: $5,000,000 per borrower across all outstanding 7(a) loans
• SBA guarantee: 85% on loans up to $150,000; 75% on loans $150,001–$5,000,000
• Maximum maturity: 25 years for real estate; 10 years for everything else (equipment, working capital, goodwill, mixed-use)
• Interest rate: typically Prime + 2.25% to Prime + 4.75% (capped by SBA rules, varies by loan size)
• Down payment: SBA-mandated minimum 10% borrower equity for change-of-ownership transactions; lenders often require more — see our SBA loan down payment guide

Why 7(a) Is the Default for Acquisitions

The acquisition of an operating business is structurally a goodwill-and-working-capital purchase. The buyer is paying for cash flow, customer relationships, brand, processes, and the operating engine — not for tangible assets at book value. Most SBA programs cannot fund goodwill or working capital, which means they cannot fund the bulk of what an acquisition actually buys. 7(a) is the only program that can.

For the full mechanics of how 7(a) acquisitions get underwritten in 2026, see our companion piece on how SBA 7(a) loans actually work for acquisitions.

SBA 504: When There's Owner-Occupied Real Estate

The 504 program is purpose-restricted and almost always part of a combination structure, not a standalone acquisition loan.

What 504 Can Fund

• Owner-occupied commercial real estate — buildings the borrower will occupy at least 51% (60% for new construction). The borrower must occupy the property.
• Major fixed equipment with a useful life of at least 10 years.
• Construction or renovation of owner-occupied facilities.
• Refinancing of existing real estate debt under specific qualifying conditions.

What 504 Cannot Fund

• Goodwill (this is the critical exclusion for acquisition deals)
• Working capital
• Inventory
• Equipment with a useful life under 10 years
• Franchise fees
• Non-owner-occupied real estate (investment properties don't qualify)

Maximum Loan Size and Structure

• Maximum SBA debenture: $5,000,000 ($5.5M for manufacturing or energy-efficient projects)
• Typical structure: 50% conventional bank loan + 40% SBA debenture + 10% borrower equity
• The 40% SBA debenture carries a long-term fixed rate (typically 5–6% in current rate environments) over 10, 20, or 25 years
• The 50% bank portion is a separate conventional loan from the lender, at the lender's terms

When 504 Fits an Acquisition

If the deal is dominated by owner-occupied real estate (e.g., a self-storage facility, a single-tenant office building you're operating from, a manufacturing plant), the 504 program is typically cheaper for the real estate component than 7(a) because:

• The 504 debenture is fixed-rate for 10/20/25 years, while 7(a) is variable
• The 504 debenture's interest rate is typically lower than the 7(a) rate
• The bank's 50% portion is a conventional loan, which may price better than SBA pricing on the same dollars

But 504 cannot fund the operating business itself. So a deal that's part real estate, part operating business typically uses:

• 504 for the real estate (50% conventional + 40% SBA + 10% borrower)
• 7(a) for the operating business piece — goodwill, working capital, equipment under 10 years

Both loans close together as part of the same transaction. The total SBA exposure across both is capped at $5M per borrower.

The 51% Occupancy Rule

The borrower must occupy at least 51% of the property's rentable square footage (60% for new construction, ramping to 80% within 10 years). This means 504 doesn't work for investment real estate, partially-occupied buildings where the borrower is only a minority tenant, or pure rental properties. The property must be operationally part of the business being acquired.

SBA Express: When Speed Matters and the Deal Is Under $500K

Express is a streamlined 7(a) variant designed for faster turnaround.

How Express Differs From Standard 7(a)

• Loan cap: $500,000 (versus $5M for standard 7(a))
• SBA guarantee: 50% (versus 75–85% on standard 7(a))
• Lender authority: Delegated — the lender approves the loan using its own credit policies and notifies the SBA, which typically issues an Express loan number within 36 hours
• Standard 7(a) timeline: SBA review of the lender's underwriting can take 5–10 business days after the lender's decision
• Express timeline: SBA loan number typically within 36 hours of lender decision

The lower SBA guarantee (50% vs. 75–85%) is the key trade-off. Lenders absorb more of the credit risk on Express loans, which makes them somewhat more conservative on credit terms and means Express loans may price slightly higher than equivalent standard 7(a) loans.

When Express Fits an Acquisition

• Deal size under $500K — and you're confident it will stay under the cap after closing costs and any working capital injection
• Speed-critical timing — competitive bidding situations where the buyer needs to close faster than standard 7(a) underwriting allows
• Partner buyouts and small equity injections post-close
• Equipment-only acquisitions that fit the cap
• Working capital additions to an existing business

Above $500K, standard 7(a) is the right vehicle even if it takes longer. Splitting a $700K acquisition into a $500K Express and a $200K conventional loan is generally a worse outcome than using a single $700K standard 7(a).

SBA Microloans: Very Small Acquisitions Only

Microloans are administered through SBA-designated intermediary lenders (typically nonprofit community development financial institutions, not banks).

Microloan Basics

• Loan cap: $50,000 (average loan size around $13,000)
• Term: up to 6 years
• Use of proceeds: working capital, inventory, supplies, furniture, fixtures, machinery, equipment. Cannot be used for real estate or to pay existing debts.
• Underwriting: by the intermediary, not the SBA directly
• Rate: typically 8–13%

When Microloans Fit an Acquisition

Rarely. The cap is too low for most operating-business acquisitions. The realistic use cases for buyers:

• Very small founder-led acquisitions (e.g., a small e-commerce business or solopreneur operation) where the total deal size fits under $50K
• Post-close working capital additions to a business already acquired through other means
• Equipment additions or replacements after close

The Microloan program is meaningful in the SBA ecosystem but is not typically the answer for someone buying a $500K+ business.

CAPLines: Working Capital Lines, Not Term Loans

CAPLines is a family of revolving working-capital line-of-credit programs under the 7(a) umbrella. There are four variants:

• Seasonal CAPLine: finances seasonal increases in AR and inventory
• Contract CAPLine: finances the direct costs of performing specific contracts
• Builders CAPLine: finances construction or renovation of buildings for resale
• Working Capital CAPLine: general short-term working capital needs

When CAPLines Fit

CAPLines are revolving credit, not term loans, so they are not the primary vehicle for an acquisition itself. They show up in two acquisition-related contexts:

• Post-close working capital that the buyer didn't fund through the 7(a) at close (e.g., the business is seasonal and needs a credit line for the off-season working capital build)
• Existing CAPLine on the target that may need to be refinanced or replaced as part of the change-of-ownership

For most buyers, a standard 7(a) sized to include adequate working capital at close is cleaner than acquiring a business and then needing to set up a CAPLine separately.

How Programs Combine on Real Deals

Most acquisitions use one SBA program. Some use two. A worked illustration of how the structure plays out on a deal with material real estate.

The $5M Shared Cap (and Why Prior SBA Borrowing Matters)

The SBA's most important sizing rule for buyers is the per-borrower aggregate cap: the total SBA exposure across all loans to the same borrower (and affiliated entities) cannot exceed $5,000,000 ($5.5M for manufacturing).

The cap applies across programs. A buyer who already has:

• A $1.5M 7(a) from a prior business
• A $750K 504 debenture on their existing facility
• A $200K Express loan

...is carrying $2.45M of SBA exposure into any new deal. The remaining capacity for a new acquisition is $5M − $2.45M = $2.55M, regardless of which program they want to use for the new deal.

This is the rule that catches serial buyers off-guard. A buyer with a successful first acquisition and an outstanding SBA loan often assumes they have full $5M capacity for the next deal. They don't — and the lender will compute the available capacity before quoting terms.

The cap also applies to affiliated entities. If you own 20%+ of two businesses and both have SBA loans, those add together for the cap. The SBA's affiliation rules are extensive — for the qualification rules around who counts as an affiliate, see our companion piece on SBA loan eligibility.

A Decision Flow: Which Program for Which Acquisition

A practical framework for thinking about which SBA program fits a given deal:

SOP 50 10 8 Updates That Changed the Rules

The SBA publishes its underwriting standards in a document called the Standard Operating Procedure 50 10. The current version, SOP 50 10 8, took effect in 2024 and includes several changes that affect how buyers should approach 7(a) acquisition loans:

• Equity injection on partial change-of-ownership transactions can include seller notes on full standby (no principal or interest payments for 24 months) as up to half of the required 10% equity. This loosens the cash equity requirement for buyers using significant seller financing.
• Refinancing rules for existing business debt have been tightened — the qualifying tests for debt refi as part of a 7(a) acquisition are more specific than under prior SOPs.
• Goodwill financing caps and the lender's responsibility to document the buyer's qualifications for goodwill-heavy deals were clarified.
• Stand-alone working capital facilities under 7(a) (not Express) have specific use-of-proceeds documentation requirements.

The SOP changes affect what your lender can do, not what they will do. Most lenders take a conservative interpretation. Sophisticated lenders (Live Oak Bank, BayFirst, and others active in the acquisition space) tend to interpret SOP 50 10 8 more aggressively than community banks doing occasional SBA deals.

For the details of how SOP 50 10 8 reshaped acquisition underwriting specifically, see how SBA 7(a) loans actually work for acquisitions.

The Bottom Line

For most buyers of operating businesses, SBA 7(a) is the right program. It is the only SBA program that can fund the goodwill, working capital, and operating assets that make up the bulk of what an acquisition actually buys.

SBA 504 is a powerful complement when the deal includes meaningful owner-occupied real estate — the fixed-rate, long-term structure of the 504 debenture can save material money on the real estate piece over a 25-year hold.

SBA Express is the right answer when the deal is under $500K and speed matters; the lower SBA guarantee makes it slightly more expensive but the faster timeline can be worth it in competitive bidding.

Microloans and CAPLines are real programs but are rarely the primary acquisition vehicle — Microloans because the cap is too low for most deals, CAPLines because they're revolving credit not term loans.

The single most important rule across all programs is the $5M per-borrower aggregate cap. A buyer with prior SBA debt brings that exposure into the new deal, which can shrink available capacity below what the deal needs. Pre-checking your existing SBA exposure before getting deep into a new acquisition is the single most underrated step in the financing process.
