Owner-occupied commercial real estate financing with as little as 10% down and a long-term fixed rate on the SBA debenture portion — structured through a bank, a Certified Development Company, and the SBA.
The SBA 504 loan is a U.S. Small Business Administration program that provides long-term, fixed-rate financing for the acquisition, construction, or renovation of owner-occupied commercial real estate and major fixed assets. Unlike a conventional single-lender mortgage, the 504 program uses a three-party funding structure: a private bank or credit union provides 50% as a first-lien loan, a Certified Development Company (CDC) — funded through an SBA-guaranteed debenture — provides 40% as a second lien at a fixed rate, and the borrower contributes a minimum of 10% equity.
The result is a financing structure that puts 90% loan-to-cost within reach for qualifying small businesses — with the CDC/SBA portion locked at a long-term fixed rate regardless of where interest rates move. This makes SBA 504 one of the most powerful commercial real estate financing tools available to owner-occupants.
As little as 10% down — compared to 20–35% required by most conventional commercial lenders for similar property types.
The SBA debenture carries a fully fixed rate for its entire term — rare in commercial lending and valuable for budgeting certainty.
No balloon payment on the debenture — fully amortizing over 20 or 25 years, significantly reducing monthly cash obligations versus shorter-term loans.
The SBA caps the CDC debenture at $5.5M, but the bank's 50% first-lien portion is uncapped — enabling projects well above $10 million.
| Term | Fixed Rate - Purchase** | Fixed Rate - Refinance** | Max LTV* | Max Amortization |
|---|---|---|---|---|
| 10 Years | 5.88% - 5.88% | 5.88% - 5.88% | 90% - Owner-Occupied | 10 Years |
| 20 Years | 6.01% - 6.01% | 6.02% - 6.02% | 90% - Owner-Occupied | 20 Years |
| 25 Years | 5.95% - 5.95% | 5.95% - 5.95% | 90% - Owner-Occupied | 25 Years |
Every SBA 504 transaction involves three separate funding sources closing in a coordinated sequence. Understanding who provides what — and in what lien position — is essential to structuring your project correctly.
Special-use properties require 15% equity; start-up businesses require 20%. The total combined loan (bank + CDC) cannot exceed 90% of the appraised value or project cost.
The bank and the CDC underwrite their portions independently but coordinate toward a single closing timeline. The bank loan typically closes first, immediately followed by the CDC debenture funding. Your Commercial Loan Direct loan officer manages coordination between all three parties on your behalf.

Eligibility for the SBA 504 program is determined by the size of the business, the nature of the project, the intended use of the property, and the business's ability to create or retain jobs.
SBA 504 is strictly a fixed-asset financing program. All proceeds must be used for the acquisition or improvement of long-life fixed assets. Working capital, inventory, and general debt consolidation are not eligible uses.
A complete, well-organized submission moves through underwriting faster and with fewer conditions. Your CLD loan officer will provide a customized checklist — the items below cover the typical core requirements.
Both programs are government-backed and owner-occupancy required, but they serve different financing objectives. Here's a direct comparison of the key decision factors:
| Feature | SBA 504 | SBA 7(a) |
|---|---|---|
| Best For | Commercial RE & fixed assets | RE, equipment, working capital, acquisitions |
| Max Loan | $5.5M CDC + uncapped bank portion | $5,000,000 |
| Down Payment | 10% (most projects) | 10–15% |
| Rate on SBA Portion | Fixed (CDC debenture) | Variable or fixed (negotiated) |
| Lender Structure | Bank + CDC (two closings) | Single lender |
| Working Capital | Not eligible | Eligible |
| Close Timeline | 60–90 days | 30–75 days |

Small businesses that already own their commercial property may be able to use the SBA 504 program to refinance existing commercial mortgage debt — in some cases pulling equity out for eligible business expenses. The refinance program operates under specific eligibility rules distinct from a purchase transaction.
The 504 refinance is particularly useful for businesses that acquired property with a conventional loan and now want to lower their payment through a longer fixed-rate structure. Equity in the property may be tapped for eligible business expenses such as maintenance, equipment, rent, utilities, or inventory obligations incurred within 18 months of application.
The CDC debenture carries a declining prepayment penalty during the first half of its term. The exact schedule depends on the debenture term selected:
Penalty applies only during the first 10 years:
No penalty from Year 11 through maturity.
The penalty is calculated on the outstanding balance of the CDC debenture, not the original loan amount. Use our calculator to estimate the exact cost of prepaying your 504 loan at any point in the term.
504 Prepayment CalculatorNote: The bank's first-lien loan may carry its own separate prepayment terms negotiated directly with the lender.
The SBA 504 process involves more steps than a conventional commercial loan — but an experienced intermediary eliminates confusion and keeps your transaction moving. Here is exactly what to expect:
Submit a quote request or call our team. We review your project details — property type, purchase price, business financials, and occupancy plan — to confirm that the SBA 504 program fits your transaction and determine whether a 10-, 20-, or 25-year debenture structure makes most sense. Pre-qualification is free and non-binding.
We match your transaction to the right bank partner and Certified Development Company from our national network. Different banks and CDCs have different underwriting appetites for property types, geography, and borrower profiles — getting this match right is the most consequential step in the 504 process.
We provide a tailored checklist and help you organize the required tax returns, financial statements, purchase agreement, environmental reports, and appraisal. The bank and CDC review your package in parallel. Complete submissions move significantly faster than piecemeal ones.
Your bank and CDC each underwrite independently. Once both are satisfied, the CDC submits to the SBA for guarantee authorization. SBA review typically takes 5–21 business days depending on program volume and submission completeness. We track status with both parties on your behalf.
Both the bank and CDC issue commitment letters with final terms and any outstanding conditions. We review these with you to confirm accuracy, identify any conditions that require attention, and ensure your timeline to closing is achievable.
The bank loan closes first — you sign loan documents, the bank disburses funds, and the property transfers. The CDC debenture then closes, typically within a few days, as the debenture is sold to investors and the proceeds are used to pay down the bank's temporary second-lien participation. Total timeline: 60–90 days from complete application.
The SBA 504 requires coordination across three parties — your bank, your CDC, and the SBA itself. Commercial Loan Direct acts as a single point of contact managing all three relationships, so your transaction doesn't fall through the cracks.
Access to SBA-preferred lenders and CDCs in all 50 states — matched to your property type, geography, and financial profile, not just the first available lender.
We understand the nuances of 504 structuring — equity injection requirements, job creation goals, special-use property rules — and keep your transaction compliant from day one.
We manage the bank and CDC underwriting timelines in parallel, preventing the delays that occur when these two processes fall out of sync.
We negotiate the bank's 50% first-lien portion across multiple lenders to ensure you get the best available rate and terms on the portion the SBA does not fix.
One dedicated loan officer from inquiry through dual closing — no being handed off between departments or repeating yourself to three different teams.
Office, retail, industrial, medical, self-storage, mixed-use, and special-use properties — we've structured 504 transactions across every eligible property type.
