The one-line difference
7(a) is flexible about what you buy; 504 is limited to long-term fixed assets but structured for large real estate and equipment projects.
The SBA's 504 page (checked October 2026) lists eligible uses as buying, building or renovating real estate, long-term machinery and equipment with at least 10 years of remaining useful life, and certain debt refinancing. It specifically excludes working capital and inventory. The 7(a) page (checked October 2026) covers real estate, working capital, equipment, refinancing, furniture and fixtures, changes of ownership and combinations of these.
Side-by-side comparison
504 offers terms up to 25 years on fixed assets through a lender plus a Certified Development Company; 7(a) offers up to $5 million for nearly any sound business purpose through one lender.
| Feature | SBA 504 | SBA 7(a) |
|---|---|---|
| Maximum amount | $5.5 million, as listed in the body of the SBA's 504 page | $5 million |
| Eligible uses | Real estate, long-life equipment, qualified refinancing | Real estate, equipment, working capital, refinancing, business purchase, mixed |
| Not allowed | Working capital, inventory, rental real estate investment | Ineligible businesses and uses under SBA rules |
| Who you deal with | A Certified Development Company plus a senior lender | One SBA-approved lender |
| Your contribution | At least 10% of project cost | Set by the lender |
| Terms | 10, 20 or 25 years | Up to 25 years for real estate; generally up to 10 for equipment and working capital |
| Rate basis | Pegged to the 10-year Treasury rate | Capped spread over a base rate |
The 504 page's introduction mentions $5 million and its body $5.5 million; ask your CDC which limit applies to your project. Terms and contribution figures come from the SBA's 504 page and its lender terms page.
How the 504 structure works
A bank lends a senior first-lien portion, a Certified Development Company lends a second portion backed by the SBA, and you contribute at least 10%.
Illustrative example. A dental group buys a $2,000,000 building. A bank funds the largest share with a first lien. A CDC funds a second share through the SBA-backed debenture. The group puts in at least 10%, here $200,000. The CDC piece carries a long fixed rate tied to the 10-year Treasury, and the SBA says the program's costs run about 3% of the debenture and may be financed into the loan.
Two loans means two sets of documents and closings, but it also means a large share of the project sits on a long fixed rate. For owners who want predictable occupancy costs for decades, that is the appeal.
Which program fits which project
Pure real estate or heavy equipment: compare both. Real estate plus working capital or a business purchase: 7(a). Anything mainly working capital: 7(a).
- Buying the building you operate in: both work. 504 often wins on long fixed pricing and a low down payment; 7(a) is simpler with one lender.
- Building a new facility: both possible; 504 is common for larger construction projects.
- A $900,000 machine with a 20-year life: 504 fits; 7(a) can too.
- Buying a business with its building: usually 7(a), because 504 does not fund goodwill or working capital.
- Inventory and payroll for growth: 7(a) only.
- Buying a rental property to lease to others: neither; passive real estate investment is ineligible.
A useful rule: if more than a small share of the money is for anything other than the building or long-life equipment, 7(a) is usually simpler, because it can cover everything in one loan.
Eligibility both programs share
Both require an operating, for-profit U.S. business that meets SBA size standards, is not an ineligible type and can repay.
Both programs exclude the business types listed in SBA rules, such as lenders, passive real estate holders and most gambling businesses. Both expect good character, sound management and a feasible plan. For real estate, the business generally must occupy most of the property itself. Confirm the occupancy rule for your project with the lender or CDC. Our guide to business loan requirements covers how lenders weigh credit, history and cash flow.
What to do next
Price the project both ways, ask an SBA lender and a CDC for written terms, and line up short-term funding if a deadline lands before closing.
- Write down the full project cost: purchase, improvements, equipment, closing costs.
- Ask an SBA 7(a) lender and a local CDC for written proposals.
- Compare total cost, down payment, prepayment terms and fixed versus variable pricing.
- Use the SBA loan calculator to check payments against your cash flow.
SBA projects take time. If a seller deadline or equipment delivery date arrives first, a faster term loan through ROI Funder can cover a deposit or bridge a short gap, at a higher cost and only with a clear payoff plan.
Frequently asked questions
Can a 504 loan be used for working capital?
No. The SBA lists working capital and inventory as ineligible uses for 504 loans. Use a 7(a) loan or another product for those needs.
Which has a lower down payment, 504 or 7(a)?
The 504 program requires at least 10% of project cost. 7(a) contributions are set by the lender and vary by project, so ask for written terms.
Can I combine 504 and 7(a)?
Some businesses use a 504 loan for a building and a separate 7(a) loan for working capital. Ask your lender and CDC whether that structure fits your project.
Is a 504 loan fixed or variable?
The CDC portion is pegged to the 10-year Treasury rate, giving long-term predictable pricing. The senior lender's portion follows the bank's terms.
Which is faster, 504 or 7(a)?
Timing depends mostly on the lender, the CDC and how complete your package is. A 504 involves two lenders and two closings, so allow for coordination time.
