Summary: The 7(a) is the generalist: up to $5 million for working capital, acquisitions, equipment, or real estate, usually variable-rate, fully amortizing over 7 to 25 years. The 504 is the real-estate and equipment specialist: a bank covers 50 percent, a Certified Development Company covers up to 40 percent at a fixed rate (up to $5 million), and you put down 10 percent. Buying owner-occupied property or heavy equipment? Start with the 504.
Two SBA programs cover most small business borrowing, and they solve different problems. The 7(a) is the Swiss Army knife: one loan for almost any legitimate business purpose. The 504 is the scalpel: built specifically for owner-occupied commercial real estate and long-lived equipment, with a fixed-rate structure the 7(a) cannot match. Picking wrong costs you either money or flexibility, so here is the head-to-head.
A 7(a) loan is a single loan from a single lender, guaranteed by the SBA. You apply once, you get one payment, and the lender handles everything. A 504 loan is actually two loans: a conventional first mortgage from a bank covering about 50 percent of the project, and a debenture from a Certified Development Company, a nonprofit the SBA certifies, covering up to 40 percent. You put down the remaining 10 percent. The CDC portion is funded by selling debentures to investors, which is why it can offer a fixed rate.
That structure is the 504's superpower and its complication. The fixed rate on the CDC portion locks in your cost for 20 or 25 years regardless of what the prime rate does, a genuine advantage when rates are climbing, as they have been into late 2026. But two lenders means two underwriters, two closings, and a longer timeline. The 7(a), with one lender and one decision, typically funds faster.
The 7(a) is usually variable-rate, capped at prime plus 2.75 percent for large long-term loans, which is 9.75 percent with prime at 7.00 percent in October 2026. Terms run 7 years for working capital, 10 for equipment, and 25 for real estate. The 504's CDC portion is fixed for 10, 20, or 25 years, historically pricing below comparable fixed-rate commercial mortgages; the bank's 50 percent portion is usually variable or a shorter fixed term.
Down payments favor the 504 for its eligible uses: 10 percent is standard for both programs, but the 504 holds that line for startups and special-purpose properties where a 7(a) lender would demand 15 to 25 percent. Loan caps: the 7(a) maxes out at $5 million total, while the 504's CDC debenture alone can go to $5 million (or $5.5 million for manufacturers and energy projects), meaning total 504 project sizes can be much larger.
The 504 is restricted to fixed assets: land, buildings, construction, and equipment with a useful life of at least 10 years. The property must be at least 51 percent owner-occupied for an existing building, or 60 percent for new construction. Working capital, inventory, and business acquisitions are not eligible.
The 7(a) funds all of those plus working capital, inventory, refinancing existing business debt, and buying an entire business including its goodwill. If your project mixes uses, say a building plus the equipment and inventory to fill it, the 7(a) handles it in one loan while the 504 would leave the soft costs unfunded.
Start with the 504 if you are buying or building owner-occupied commercial real estate or buying heavy equipment with a long life, especially if you want a fixed rate and have only 10 percent down. Start with the 7(a) if you need working capital, are buying a business, are refinancing, or have a mixed-use project. When in doubt, talk to both a 7(a) lender and a CDC: the programs are not competitors, and good advisors will point you to the other one when it fits better.
Yes. Many businesses carry both: a 504 for the building and a 7(a) for working capital or equipment. Each loan is underwritten separately.
The CDC's portion (up to 40 percent) is fixed for 10, 20, or 25 years. The bank's 50 percent first mortgage is typically variable or a shorter-term fixed rate.
Ten percent is standard, even for startups and special-purpose properties. The bank takes the first-lien 50 percent, the CDC takes the second-lien debenture.
The 7(a) is usually faster because it has one lender and one underwriting decision. The 504 adds the CDC as a second underwriter, which extends the timeline.
