What is an SBA loan? 7(a) vs 504 explained (2026)

Full answer

SBA loans are not made by the SBA itself — they're made by approved private lenders (banks, credit unions, certified development companies, fintechs like SmartBiz) with a partial guarantee from the SBA. That guarantee (typically 50-85% of the loan amount) is what lets lenders extend longer terms and lower rates than they would otherwise tolerate for small business credit.

SBA 7(a) program — the workhorse. (1) Max loan size: $5M. (2) Use of proceeds: working capital, debt refinance (including MCA refinance), business acquisition, partner buyout, equipment, owner-occupied real estate, leasehold improvements. (3) Rate: Prime + 2.25-4.75% in 2026 (variable rate most common; fixed rates available but rare). (4) Term: up to 10 years working capital, up to 25 years for real estate. (5) Down payment: 10-20% for acquisitions; not required for working capital refinance. (6) Collateral: required when available but lender cannot decline solely for insufficient collateral. (7) Personal guarantee: required from all owners with 20%+ stake.

SBA 504 program — for real estate and heavy equipment. (1) Max loan size: $5.5M from SBA-debenture portion (total project can be larger with bank-first lien). (2) Use of proceeds: limited to owner-occupied commercial real estate purchases, ground-up construction, major renovation, and heavy equipment with 10+ year useful life. Not eligible for working capital, debt refinance, or inventory. (3) Structure: 50% bank first-mortgage + 40% SBA-debenture second-mortgage (via CDC) + 10% borrower equity. (4) Rate: SBA portion is fixed-rate (locked at debenture sale, typically 5.5-7.5% in 2026). Bank portion priced independently. (5) Term: 10, 20, or 25 years. (6) Job creation requirement: must create or retain 1 job per $75K of SBA funding (waived for manufacturers and certain community priority projects).

Which to choose. (1) Choose 7(a) if: buying a business, refinancing high-cost debt (MCA, etc.), funding working capital, mixed-use needs, or you need program flexibility. 7(a) is the default — when in doubt, this is the answer. (2) Choose 504 if: buying owner-occupied commercial real estate, doing major renovations, purchasing heavy equipment with long useful life, and you don't need working capital in the same transaction. The fixed-rate debenture is attractive in rising-rate environments.

Other SBA programs to know briefly. (1) SBA Express: subset of 7(a), up to $500K, 36-hour SBA response, lower guarantee (50%) — faster but lender takes more risk so rates can be slightly higher. (2) SBA Microloan: up to $50K, made via intermediary nonprofits, often used by startups. (3) SBA CAPLines: revolving lines of credit under the 7(a) umbrella. (4) SBA EIDL: disaster loans (largely COVID-era residual servicing in 2026). For most working-capital and acquisition needs, standard 7(a) is the right starting point.

Bottom line: SBA 7(a) is the general-purpose program for working capital, refinance, and acquisition (up to $5M, Prime + 2.25-4.75%, up to 25 years). SBA 504 is the specialized program for owner-occupied commercial real estate and heavy equipment with fixed-rate financing. Both require 650+ credit, 2+ years operating, and 60-90 day timelines. If you're refinancing MCA debt or need working capital, you want 7(a). If you're buying a building or major equipment, evaluate 504 against 7(a) on rate and term.
