- SBA 504 loans provide low-down-payment, long-term fixed-rate financing for owner-occupied commercial real estate.
- CDC debenture rate for October 2025 is approximately 6.5%–7.5% fixed (SBA weekly debenture data).
- The bank portion rate is negotiated separately; the blended all-in rate is 7.0%–8.5%.
- Suitable when Business owners who will occupy at least 51% of a commercial property for 10 years or more.
- Less suitable when Borrowers who need a quick close or who plan to sell or refinance within 10 years.
SBA 504 loan rates for October 2025 are approximately 6.5% to 7.5% fixed for the CDC portion of the loan, depending on the debenture pricing date. The borrower's bank-financed portion (typically 50%) is negotiated separately at a variable or fixed rate. The SBA 504 program provides a long-term, fixed-rate financing option for owner-occupied commercial real estate and major equipment purchases, with down payments as low as 10%.
Many small business owners compare the 504 loan to conventional commercial mortgages, which as of September 2025 averaged around 7.5% to 8.5% for owner-occupied properties (Federal Reserve Senior Loan Officer Opinion Survey, Q3 2025). The 504's CDC portion rate is set at the time the debenture is sold on the secondary market, typically when the loan closes, so the exact rate a borrower receives can vary from the published estimate. This guide covers current rate ranges, how they are determined, eligibility rules, and the steps to apply.
1. What Are SBA 504 Loan Rates in October 2025?
What Are SBA 504 Loan Rates?
The SBA 504 loan rate in October 2025 is a blended rate with two components. The first component is the CDC portion, typically 40% of the project cost, which is funded by a government-guaranteed debenture sold to investors. This portion carries a below-market, fixed rate for the full term (20 or 25 years). The second component is the bank-funded portion, typically 50% of the project, which is negotiated directly with the lender at a market-based rate, either fixed or variable. The borrower's equity injection is 10%.
For October 2025, the CDC debenture rate is approximately 6.5% to 7.5% fixed for the 20- or 25-year term, based on the SBA's published debenture rate data. This rate is set weekly on Wednesdays when the SBA sells its debentures; the borrower's rate is locked when the loan closes and the debenture is priced. The bank portion rate typically ranges from prime rate (currently 8.5% as of October 2025, per the Wall Street Journal) plus 0% to 2.75% or a fixed rate of 7.5% to 9.0%.
| Loan Component | Typical Share of Project | Rate Type | October 2025 Rate Range |
|---|---|---|---|
| CDC Debenture (SBA portion) | 40% (up to $5 million; $5.5M for manufacturing) | Fixed for 20 or 25 years | 6.5% – 7.5% |
| Bank Loan (conventional portion) | 50% | Variable (prime + spread) or fixed | 7.5% – 9.0% (fixed); prime + 0% to + 2.75% (variable) |
| Borrower Equity | 10% (or more) | -- | -- |
The blended, effective all-in rate on a 504 loan, counting both the CDC and bank portions, typically lands between 7.0% and 8.5% in October 2025, depending on the specific bank rate negotiated and when the debenture is priced. That is often below a conventional commercial mortgage, which as noted above averaged 7.5%–8.5% for owner-occupied properties.
One important nuance: the CDC rate is set at closing, not at application. If rates move up or down while the loan is being processed, the borrower's final rate will reflect the market on the day the debenture is priced. Some borrowers may choose to lock the bank portion rate at application to reduce uncertainty.
2. How the SBA 504 Loan Rate Is Determined
The CDC debenture rate is set through a weekly auction. The SBA aggregates approved loans from Certified Development Companies across the country, pools them into a debenture, and sells that debenture to institutional investors. The yield required by investors on that debenture determines the rate for all loans in that week's pool. The borrower's rate is the debenture yield plus a small servicing fee (typically 0.5%–1.0%).
Factors that influence the debenture rate include:
- U.S. Treasury yields: The debenture is priced with a spread over the comparable-maturity Treasury note (e.g., the 20-year Treasury for 20-year loans). In October 2025, the 20-year Treasury yield is approximately 4.5%–5.0%.
- Demand from investors: The SBA debenture carries the full faith and credit guarantee of the U.S. government, so it trades like an agency security. Strong demand pushes rates lower; weak demand pushes them higher.
- Loan size and volume: Larger pools may achieve slightly better pricing, but the impact on an individual borrower's rate is minimal.
Because the rate is set weekly, borrowers cannot lock a rate in advance on the CDC portion. The bank portion, by contrast, can be locked at application or at closing, the terms are negotiated with the individual lender. Many borrowers choose to negotiate a competitive fixed rate on the bank portion to lock in predictable payments.
Here is the step-by-step sequence of how the rate is applied:
- Apply with a Certified Development Company. The CDC reviews eligibility and begins the SBA approval process.
- The lender approves the bank portion. The bank negotiates its rate (fixed or variable) and provides a commitment letter.
- SBA approves the debenture portion. The CDC notifies the SBA of the approved project.
- Loan closing. The CDC schedules the debenture sale. The rate is set on the Wednesday when the SBA sells that week's pool.
- Funds disbursed. The debenture proceeds plus the bank loan and borrower equity fund the project.
The result: the borrower knows the exact rate for the CDC portion only at closing, but the range and the timing are predictable. Borrowers planning a closing should monitor weekly debenture rate data published by the SBA (sba.gov) to estimate their rate.

Who Is Eligible for an SBA 504 Loan?
The SBA 504 loan is designed for for-profit businesses that occupy at least 51% of the property being financed (for new construction) or 60% (for existing buildings). The business must also meet the SBA's size standards, generally, under $15 million in tangible net worth and under $5 million in average net income over two years.
| Requirement | Detail |
|---|---|
| Business type | For-profit, located in the US, not engaged in speculative real estate or other excluded activities |
| Owner occupancy | 51% (new construction); 60% (existing building); 100% for equipment financing |
| Size standard | Tangible net worth ≤ $15 million; average net income ≤ $5 million for past two years |
| Use of funds | Purchase or construction of owner-occupied commercial real estate; purchase of long-term equipment (10+ year life) |
| Maximum loan | $5 million (up to $5.5 million for manufacturing); $2 million for equipment |
| Down payment | 10% (or more); start-ups or special-purpose buildings may require 15%–20% |
Loan terms for the CDC portion are either 20 years (for equipment) or 25 years (for commercial real estate). The bank portion typically matures in 10 to 20 years, though longer terms are possible. There are no prepayment penalties on the CDC debenture portion for the first 10 years; after that, there is a declining prepayment fee (6% in year 10, stepping down 1% per year). The bank portion's prepayment terms are negotiated with the lender.
Fees on the CDC portion are limited by the SBA: a CDC servicing fee of 0.5%–1.0% (included in the rate), a processing fee of approximately 1.5% of the debenture amount, and third-party costs (appraisal, environmental report, legal). The bank may charge origination fees as well. Total upfront costs typically run 3%–6% of the total project amount.

VIEW SBA 504 ELIGIBILITY →4. Risks, Pros, Cons, and When to Consider an SBA 504 Loan
The SBA 504 loan is a strong choice for owner-occupants seeking a low down payment and long-term, fixed-rate financing. However, it comes with trade-offs and risks.
Key risks and limitations:
- Rate determined at closing: The CDC debenture rate is set on the closing date, not at application. If rates rise while the loan is being processed, the final cost may be higher than estimated.
- Bank portion is a separate negotiation: The bank-funded 50% comes at market rates, which can be variable. That component may carry a higher rate than a conventional mortgage.
- Two sets of fees: Borrowers pay fees to both the CDC (servicing, processing) and the bank (origination, underwriting). Total upfront costs can reach 6%.
- Occupancy requirement: The business must occupy at least 51% of the property. If you plan to lease out part of the building, the 504 may not work.
- Prepayment penalty on CDC portion: A declining prepayment fee applies for the first 10 years. If you sell or refinance early, you could owe a penalty.
Advantages include the low down payment (10%), a below-market fixed rate on the CDC portion for 20–25 years, and the absence of a balloon payment. The 504 also allows the borrower to finance up to $5 million in real estate (or $5.5 million for manufacturing).
Disadvantages include the two-layer rate structure (CDC + bank), the risk of a higher-than-expected CDC rate at closing, and the relatively slow processing time (60–90 days on average).
Expert Tips
- Compare the blended all-in rate (bank portion + CDC portion) against a conventional commercial mortgage to see which is lower.
- Negotiate the bank portion rate before the CDC portion is priced, you want the best possible terms on that piece.
- Monitor the SBA's weekly debenture rate for at least four weeks before your planned closing to understand market direction.
- Work with a Certified Development Company (CDC) that has a strong track record of closing loans and can estimate your likely debenture rate range.
- Consider a 504 loan if you are buying a building you'll occupy for 10 years or more, the long-term fixed rate and low down payment are most valuable over that horizon.
Mistakes to Avoid
- Assuming the CDC portion rate is locked at application, it is not; budget for potential rate increases.
- Choosing a variable-rate bank portion without understanding that rising rates could increase your total cost.
- Ignoring the prepayment penalty on the CDC portion, if you plan to sell the property within 10 years, the penalty could be significant.
- Not comparing the 504 to an SBA 7(a) loan, which offers more flexible uses but higher rates and shorter terms.
Pros and Cons
- ✅ Low down payment (10%), preserves working capital.
- ✅ Fixed, below-market rate on the CDC portion for 20–25 years.
- ✅ No balloon payment, fully amortizing term.
- ✅ Eligible for up to $5 million in financing.
- ❌ CDC rate is determined at closing, no lock before that.
- ❌ Bank portion is separate and may carry a higher rate than a conventional mortgage.
- ❌ Two sets of fees (CDC + bank), total upfront cost 3%–6% of project.
- ❌ Prepayment penalty on CDC portion for the first 10 years.
Bottom Line
The SBA 504 loan in October 2025 offers a competitive all-in rate of approximately 7.0%–8.5%, often below conventional commercial mortgage rates, combined with a low 10% down payment. It is a strong option for business owners who will occupy the property long term, but borrowers should be prepared for the two-layer rate structure, the fact that the CDC portion rate is set at closing, and a slower (60–90 day) process.
