How a 504 deal is built
Every 504 project stacks three funding sources, and the borrower’s share is what people mean by the down payment. The bank piece is negotiated directly. The CDC piece is a bond issued through the SBA’s debenture program, which is where the program’s fees live.
What the money can buy
What it cannot buy, in general: working capital, inventory, investment property, and anything speculative. A 504 is a fixed-asset program. Businesses needing both a building and working capital often pair a 504 with a separate 7(a) line rather than stretching one program over both.
- Owner-occupied commercial real estate. The business must occupy at least 51% of an existing building; new construction typically starts at 60% occupancy with a path to 80% over time. Your CDC confirms current thresholds.
- Long-life machinery and equipment. Heavy equipment with a useful life of ten years or more, such as production lines and presses.
- Construction and expansion. Building new facilities or major renovations of the ones you will occupy.
- Refinancing qualified real estate debt. Allowed in defined situations, with rules your CDC can check quickly.
Borrower requirements
| Requirement | In practice |
|---|---|
| For-profit, US-based small business | Same size-standard logic as 7(a); your NAICS code sets the cap. |
| Net income and tangible net worth limits | The program caps these at generous levels designed to exclude only genuinely large firms; most applicants clear easily. |
| Economic development test | Most projects must meet a jobs-creation or public-policy goal; there are alternative tests for smaller and rural borrowers. Your CDC screens this early. |
| Equity injection | Typically 10% of the project; new businesses and single-purpose properties can see 15% or more. |
| Personal guarantee | Owners of 20% or more generally guarantee the debenture personally. |
| Occupancy | 51% of existing space (60% rising to 80% for new construction, per current rules). |
The CDC’s role, and why the timeline differs
The CDC is a nonprofit licensed by the SBA to package and service 504 loans, and it changes the process in two ways. First, there is another institution in the deal: the bank approves its piece, the CDC assembles the debenture, and both run their own checks. Second, debentures are funded in scheduled pools, so closing dates follow the funding calendar rather than your convenience. None of this is a reason to avoid the program; it is a reason to start earlier and to read how long SBA approval takes with 504-specific eyes.
504 or 7(a)? The honest comparison
| 504 | 7(a) | |
|---|---|---|
| Best for | Owner-occupied real estate and heavy equipment | Working capital, acquisitions, most everything else |
| Rate structure | Long fixed rates on the debenture | Variable, prime plus capped spread |
| Down payment | Typically 10% | 0–10% depending on the deal’s strength |
| Speed | Slower: two lenders plus a funding calendar | Faster, especially at delegated lenders |
| Working capital | Generally not eligible | A core use of the program |
Model the whole thing before you call a CDC
The 504’s blended economics (a bank piece, a fixed-rate debenture, your injection) are exactly what its calculator is for. Put your project numbers into the 504 loan calculator and you will see the blended payment and the fee impact on the debenture. Walk into the CDC conversation with that page open; it changes the quality of the discussion immediately.
