The SBA 504 loan offers some of the lowest interest rates available for purchasing commercial real estate or major equipment — often 1%–2% below conventional commercial financing. The trade-off: a more complex approval process involving two lenders, and strict restrictions on how funds can be used. For the right purchase, it’s one of the best deals in small business lending.
How the SBA 504 Loan Is Structured
The 504 loan is a three-party structure:
| Component | Who Provides It | Loan Amount | Rate | Term |
|---|---|---|---|---|
| First mortgage | Bank or credit union | 50% of project | Variable (prime + spread) | 10–25 years |
| Second mortgage | CDC backed by SBA | 40% of project | Fixed | 10 or 20 years |
| Down payment | Borrower | 10% of project | N/A | N/A |
Special case — higher down payment: For startup businesses (under 2 years old) or special-use properties (hotels, car washes, gas stations, restaurants with specialized equipment), the down payment rises to 15%–20%.
Example — $1,500,000 commercial real estate purchase:
- Bank first mortgage: $750,000 (50%)
- SBA/CDC second mortgage: $600,000 (40%)
- Borrower down payment: $150,000 (10%)
This compares favorably to conventional commercial real estate loans, which typically require 20%–30% down — a $300,000–$450,000 down payment for the same property.
SBA 504 vs. SBA 7(a) Loan
| Feature | SBA 504 | SBA 7(a) |

Current 2026 Rates
The SBA/CDC portion rate is set monthly based on the 5- and 10-year US Treasury note rates plus spreads for CDC debenture servicing.
Approximate 2026 rates (verify with lender for current month):
- 10-year term CDC debenture: ~6.2%–7.0%
- 20-year term CDC debenture: ~6.5%–7.3%
- Bank first mortgage (variable): prime rate + 1%–2.75% (prime is currently 7.5% in 2026, giving 8.5%–10.25%)
The bank’s 50% portion typically has a higher rate than the SBA’s 40% portion. The blended effective rate for the total loan is usually 7%–9.5%, depending on the mix.
How to Apply
Step 1 — Find a Certified Development Company (CDC). The SBA’s website has a CDC directory. CDCs are nonprofit organizations that manage the SBA portion of 504 loans. Select one in your state.
Step 2 — Find a participating bank or credit union. Your CDC often has lender relationships and can refer you to banks experienced in 504 first mortgages. Your existing business bank is a good starting point.
Step 3 — Prepare your documentation:
- Personal financial statement (SBA Form 413)
- 3 years of personal and business tax returns
- YTD profit & loss statement and balance sheet
- Business debt schedule
- Business plan with projections (especially for startups)
- Purchase agreement or letter of intent for the property or equipment
- Environmental assessment (for real estate)
- Appraisal
Step 4 — Submit applications to both the bank and CDC simultaneously. Each lender conducts its own underwriting. The CDC also submits to the SBA for final approval.
Step 5 — Closing. Both loans close simultaneously. Expect 60–120 days total.
Jobs Creation Requirement
The SBA 504 program requires the business to create or retain one job for every $90,000 of SBA financing ($120,000 for manufacturers). For a $1M SBA debenture, you’d need to create or retain approximately 11 jobs.
If your project doesn’t meet the job creation test, it may still qualify under alternative public policy goals:
- Business district revitalization
- Energy efficiency improvements (10% energy reduction)
- Minority or women-owned business development
- Rural business development
