SBA 7(a) vs SBA 504: Which Program Fits Which Deal
Loan size, use of proceeds, down payment, and rate trade-offs in plain English.
The Core Difference: General-Purpose vs Fixed-Asset
SBA 7(a) is the agency's general-purpose program. One loan, capped at $5M, with 10% borrower equity, 25-year amortization on real estate (10-year on equipment, 7-year on working capital), and a use-of-proceeds list that includes business acquisition, working capital, real estate, equipment, refinancing, and franchise fees. It is the Swiss-army-knife loan: broad eligibility, faster approval, but a variable rate priced over Prime.
SBA 504 is the fixed-asset program. Two loans stacked: a 50% bank first mortgage at market rate, a 40% CDC second mortgage at long-term fixed rate (currently in the 6.5–7.0% range), and 10% borrower equity. The CDC piece is capped at $5.5M ($5.5M for energy-efficient projects, $5M general) but the total project size can run to $10–11M because the bank first is uncapped. Use is restricted to owner-occupied real estate, major equipment, and building improvements.
The mental model: 7(a) buys a business including its real estate. 504 buys real estate that a business will occupy. Get this distinction right at the screening stage and you save weeks.
Down Payment, Rate, and Amortization
On equity, both programs require 10% from the borrower in standard cases, but 7(a) bumps to 15% on changes-of-ownership and 504 bumps to 15% on single-purpose properties or new businesses, and 20% on both. The seller can fund up to half the equity via a standby note in either program, but the standby terms differ — 7(a) requires 24-month full standby, 504 allows partial standby with interest-only payments.
On rate, 7(a) prices at Prime + 1.5% to Prime + 2.75% (variable, repricing quarterly) for most deals. 504 prices the CDC piece at a fixed bond rate set monthly — over the last 24 months it has run 6.0–7.5% on the 25-year debenture. The bank first on 504 is conventional commercial debt, often 5-year fixed with 25-year amort. Net effect: 504 is dramatically cheaper for owner-occupied real estate over a long hold.
On amortization, both programs offer 25 years on real estate. 7(a) offers 10 years on equipment and 7 years on working capital; 504 doesn't fund either — those uses go to a 7(a) sister loan if needed. 7(a) has no prepay penalty after the third year on a 25-year loan; 504 has a 10-year declining prepay schedule on the CDC piece.
When to Choose 7(a)
Choose 7(a) when speed, flexibility, or working capital is the binding constraint. Business acquisitions almost always go 7(a) because the program funds goodwill — 504 doesn't. Owner-user deals where less than 51% of the building will be owner-occupied also go 7(a), because 504 requires 51% owner-occupancy on existing buildings (60% on new construction).
The 7(a) advantage on speed is real: a typical 7(a) closing runs 45–75 days vs 60–90 days for 504, because 504 has the additional CDC processing layer. If the seller has an aggressive close-date demand, 7(a) is often the only realistic SBA path.
7(a) also wins for partial-purpose deals — buying a business plus the real estate it occupies plus working capital plus equipment, all in one loan. 504 would require splitting that into a 504 (real estate) plus a 7(a) (everything else), doubling the documentation load.
When to Choose 504
Choose 504 when you are buying or building owner-occupied real estate and you intend to hold for 5+ years. The fixed-rate CDC piece protects 40% of the capital stack from rate shocks — and over a 25-year hold, that protection compounds into hundreds of thousands of dollars saved relative to a fully variable-rate 7(a).
504 is the right answer for ground-up construction of owner-occupied facilities. The program funds construction interest reserves, soft costs, and FF&E; the rate-fix at conversion to permanent removes a major risk. SBA-eligible green-building improvements (LEED, Energy Star) qualify for the higher $5.5M CDC cap.
504 is also the move for medical/dental, manufacturing, hospitality, and any owner-occupied special-use real estate where the alternative is a 65% LTV bank loan. Pulling 90% leverage at a 25-year fixed rate is a structural advantage no conventional lender will match. The trade-off is the longer close and the prepay penalty — both manageable if the hold is genuinely long-term.
