The SBA 504 loan program is designed for one purpose: financing fixed assets — primarily owner-occupied commercial real estate and major equipment over $250K. It is not a working-capital product. A merchant comparing an MCA to a 504 is almost always asking the wrong question; the right framing is "should I take an MCA for working capital while financing the asset separately via 504?"
Cost comparison for a $500K asset purchase, 20-year amortization.
| Product | Effective rate | Total interest |
|---|---|---|
| SBA 504 (20-year debenture) | ~6.5% APR | ~$280,000 interest |
| Conventional commercial mortgage | ~7.5–9% APR | ~$340,000–$430,000 interest |
| Bank business term loan, 7-year | ~8.5% APR | ~$160,000 interest (but shorter horizon) |
| 1.30 factor MCA, $500K (if available, which it usually is not at that size) | ~50% APR | $150,000 cost in 9 months, recurring |
For asset financing, the 504 is dramatically cheaper than any short-term product. An MCA is never the right tool for a $500K real estate purchase — wrong horizon, wrong cost, often not even an option at that size.
504 structure.
A 504 loan is actually two loans: - 50% from a bank (first lien on the asset). - 40% from a Certified Development Company (CDC) backed by an SBA-guaranteed debenture (second lien on the asset). - 10% borrower equity (down payment).
The CDC portion locks in a long-term fixed rate at the debenture sale (monthly). The bank portion can be fixed or floating. Combined effective rate runs 6–7% in 2026.
Eligible uses.
- Purchase of owner-occupied commercial real estate (at least 51% owner-occupied; 60%+ for new construction).
- Construction of new owner-occupied buildings.
- Heavy equipment with useful life over 10 years.
- Improvements to existing real estate (parking, lighting, HVAC, landscaping).
Ineligible uses: - Working capital. - Inventory. - Marketing or general operating expenses. - Refinance of working capital debt. - Goodwill or intangibles in business acquisition.
This is why the MCA vs. 504 comparison is usually misleading.
A restaurant owner needing $100K for payroll, inventory, and tax obligations cannot use a 504 at all. The 504 is not in their consideration set. The MCA is.
A restaurant owner buying a $700K building to relocate the restaurant should never use an MCA for that purpose — wrong horizon, wrong cost. The 504 (or a conventional commercial mortgage) is the right tool.
Approval timeline.
- 504 origination: 60–120 days (bank underwriting, CDC underwriting, SBA approval, appraisal, environmental, title).
- MCA origination: 4 hours to 3 business days.
Approval criteria.
- 504: 2+ years operating, personal credit 680+, ability to demonstrate cash flow service to cover the new debt, 10% equity injection, no recent bankruptcies, owner-occupied use of the asset.
- MCA: 6+ months operating, personal credit 580+, $15K+/month revenue.
The combined play: MCA for working capital + 504 for the asset.
A merchant acquiring a building (504) often has parallel working-capital needs — moving costs, build-out, new equipment beyond what the 504 financed, inventory for the new location, marketing for the relocation, payroll during transition. The 504 cannot fund any of those. An MCA can.
Sophisticated owners stack: 504 closes for the building (cheap, long-term), MCA funds in parallel for the working-capital wrap (expensive, short-term). The total cost-of-capital blended is far below pure-MCA.
When 504 is the right answer.
- Buying owner-occupied commercial real estate.
- Buying or building a major facility.
- Acquiring heavy equipment over $250K with 10+ year useful life.
- Long time horizon (60–120 days acceptable).
- Strong financials.
When MCA is the right answer.
- Working capital need.
- Short horizon.
- Asset is not eligible for 504 (e.g., vehicles under 10-year useful life, restaurant smallwares, software).
Common confusion. First, "504 can refinance my MCA" — generally no, unless the original MCA proceeds funded eligible 504 assets (rare). Second, "504 requires 10% down" — yes, sometimes 15% for new businesses or special-purpose properties. Third, "504 is faster than 7(a)" — generally no, often slower because of the CDC and debenture-sale timing. Fourth, "I can use 504 for working capital after closing on the building" — no, the SBA tracks use-of-proceeds.
As of 2026-06-30, the playbook. Use 504 for the fixed asset, MCA for parallel working-capital needs. Never substitute one for the other; they are not interchangeable products.

- MCA vs loan (legal distinction) — An MCA is legally a purchase of future receivables, not a loan. This distinction exempts MCAs from state usury caps but requires specific contract structure — including reconciliation provisions.
- Merchant cash advance (MCA) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan.
- Business funding options compared — The 2026 small business funding stack: SBA loans (cheapest, slowest), bank term loans + LOCs (cheap, slow, strict credit), fintech term loans + LOCs (medium cost, faster), invoice factoring (medium, AR-secured), equipment financing (medium, asset-secured), MCAs (most expensive, fastest, loosest credit).
