SBA 7(a) is general-purpose up to $5M; SBA 504 is owner-occupied real estate and heavy equipment up to $5.5M with a structurally different pricing mechanism. Rate structure, fees, down payment, timeline, and the worked-example scenarios where each one wins.
Purpose, pricing structure, and use of proceeds. SBA 7(a) is the general-purpose SBA program — up to $5M, used for working capital, debt refi, acquisition, real estate, equipment, or any combination. SBA 504 is purpose-specific — up to $5.5M, used only for owner-occupied commercial real estate or long-lived heavy equipment, with the loan structured as a 50% first mortgage (a bank or non-bank lender) plus a 40% CDC debenture (a Certified Development Company issuing SBA-guaranteed bonds) plus 10% borrower equity. 504's CDC piece is fixed below-market because it's funded by tax-exempt SBA-guaranteed debentures; 7(a) is typically variable Prime + a regulated spread.
On a $1M owner-occupied real estate purchase: $500K first mortgage from a bank (50%, conventional rate, typically 25-yr amortization), $400K CDC second from a Certified Development Company (40%, fixed-rate SBA debenture pricing, 25-yr term), and $100K borrower equity (10%). Two loans, one transaction. The CDC piece is what makes 504 economically distinct — the rate is fixed for the full 25 years at the debenture rate (currently in the 5–7% range, well below conventional commercial real estate rates). The bank piece prices at whatever the bank charges.
504 almost always wins on real estate. The blended effective rate of the two-loan 504 structure (bank piece at, say, 7% + CDC piece fixed at ~6%, weighted 50/40) typically beats a $1M 7(a) at Prime + 2.5% (variable). The bigger benefit is the fixed-rate CDC piece — 25 years of fixed pricing on 40% of the deal protects against rate-cycle exposure. The CDC fee load is real (3.5% upfront on the CDC piece) but amortizes over 25 years.
7(a) only — 504 cannot be used for working capital. 504 is restricted to long-lived fixed assets (owner-occupied real estate and equipment with a useful life ≥10 years). If your need is working capital, debt refi, business acquisition (going concern), or any combination of soft uses, 7(a) is the only SBA program that applies. The CAPLines variant of 7(a) is the working-capital-specific structure.
Both programs require 10% borrower equity injection in most cases. 504 is explicit: 10% borrower equity is built into the 50/40/10 structure. 7(a) requires 10% equity for new businesses (under 2 years), real estate, and acquisitions; existing established businesses sometimes get to 0% down on certain working capital deals. Specialty 504 transactions — startups, special-purpose properties, or both — can require 15% or 20% borrower equity per SBA SOP. Always confirm with the lender or CDC for the specific deal.
7(a): 30–90 days application to funding depending on lender (Preferred Lender Program at 30–60 days; standard processing at 60–90). SBA Express 7(a) variants up to $500K can fund in as fast as 30 days. 504: 60–120 days — the two-loan structure adds time because both the bank piece and the CDC piece have to be underwritten and closed, and the CDC debenture is pooled and sold monthly (the funding date depends on the debenture sale calendar). For time-sensitive real estate closings, this matters; some 504 deals use bridge financing to close on time and refi into the 504 structure after debenture funding.
7(a): SBA guarantee fee on a sliding scale by loan size — 0% on the first $1M for loans approved under fee waiver authority, then 0.55% / 1.05% / 3.0% / 3.75% on tiers above. Lender packaging and closing fees on top. 504: 3.5% upfront fee on the CDC debenture piece (which is the 40% portion), funding fees, processing fees, and the SBA guarantee fee on the debenture. The CDC fee structure looks higher on the surface but amortizes over 25 years and applies only to the 40% CDC piece — so the all-in cost is competitive.
Yes — and sometimes it's the right structure. If you're buying a building for $1M and need $300K of working capital to support the move-in, the optimal structure is a 504 on the building ($500K bank + $400K CDC + $100K equity = $1M real estate) plus a separate 7(a) for the working capital ($300K). Two SBA loans on one transaction. The lender can sometimes package both together. The trade-off is operational complexity and longer total closing time.
Variable is the default for 7(a). The SBA caps the spread (Prime + 3.0% to Prime + 6.5% depending on loan size and term), and most lenders quote at the regulated cap or slightly below. Fixed-rate 7(a) is available but priced higher (typically Prime + 2 to Prime + 3 fixed for a 5–10 year fixed period, then variable). The CDC piece of a 504 is the only SBA structure that's fixed for the full 25-year term at debenture-grade pricing — that's the structural advantage 504 brings.
Both programs treat startups conservatively. 7(a) startup deals: 10% equity required, sometimes more depending on industry and use of proceeds; the equity must be the borrower's own cash (gifts and seller notes have specific treatment rules under SOP 50 10). 504 startup deals: 15% equity required when the borrower is a startup (under 2 years), 15% equity required when the property is special-purpose (hotel, restaurant, gas station, etc.), and 20% when both apply simultaneously. Read the current SBA SOP — these rules update periodically.
