You can refinance an SBA 504 loan, and there are two directions it can go. If you already carry commercial debt, you can roll it into a new 504 loan — either on its own or bundled with a new project. If you already have a 504 loan and want out, you can prepay it and move to conventional financing or an SBA 7(a) loan, but a prepayment premium applies for roughly the first half of the loan’s term. Each path has its own eligibility rules, timing, and costs, and choosing the wrong one can add months or thousands of dollars to the process.
Rolling Existing Debt Into a New 504 Loan
The 504 program offers two separate refinancing tracks under 13 CFR § 120.882. Which one applies depends entirely on whether you’re also taking on a new project.
Refinancing Without Expansion
This track, under 13 CFR § 120.882(g), lets you replace existing commercial debt with a 504 loan when no new construction, real estate purchase, or major equipment acquisition is involved. To qualify, the business must have been operating for at least two years as of the application date, and the debt being refinanced must have been incurred at least six months before you apply.1eCFR. 13 CFR 120.882 – Eligible Project Costs for 504 Loans
The debt itself has to qualify. At least 75% of the original loan proceeds must have gone toward an eligible fixed asset — land, a building, or long-term equipment. The debt cannot already carry a federal guarantee. If the loan you’re refinancing was itself a refinancing of an earlier loan, the original loan must have met the same asset test.
The combined 504 loan and third-party loan cannot exceed 90% of the fair market value of the fixed assets securing the project. You contribute at least 10% equity, excluding administrative costs. The 504 portion itself is capped at no more than 40% of the collateral value, and the third-party lender must cover at least an equal share.1eCFR. 13 CFR 120.882 – Eligible Project Costs for 504 Loans
Refinancing With Expansion
If you’re already pursuing a new project — buying property, constructing a facility, or acquiring major equipment — you can fold existing commercial debt into the 504 loan for that project. Under 13 CFR § 120.882(e), the debt you refinance cannot exceed the total cost of the expansion itself. If your expansion costs $800,000, you can refinance up to $800,000 in existing debt, not $900,000.2eCFR. 13 CFR 120.882 – Eligible Project Costs for 504 Loans
This track has a lower bar to entry. There is no two-year operating history requirement for the expansion component, though the existing debt still must be at least six months old. Because the expansion itself must represent a real new investment, the SBA scrutinizes whether the project is a genuine business need or a vehicle built around the refinancing provisions.
Cash-Out for Eligible Business Expenses
A rule change that took effect in November 2024 significantly expanded what you can do with the proceeds. The old cap limited cash-out for eligible business expenses to 20% of the fair market value of the fixed assets securing the debt. That cap is gone. Under the refinancing-without-expansion track, you can now receive cash for eligible business expenses up to the full 90% loan-to-value limit, as long as the cash portion exceeds what’s owed to the existing lender.3Regulations.gov. 504 Debt Refinancing
Eligible business expenses include operating costs, and certain secured debts incurred before the 504 application also qualify. Credit card balances and business lines of credit can be included if the accounts are in the business’s name and you certify the charges were exclusively business-related. Both the CDC and the borrower have to certify how the funds will be used, and you need to be ready to document the spending afterward with bank statements, invoices, or cleared checks.3Regulations.gov. 504 Debt Refinancing
One boundary: 504 loans still cannot be used directly for working capital or inventory purchases. The cash-out provision is for documented business expenses, not a general-purpose credit line.4U.S. Small Business Administration. 504 Loans
Loan Size, Rates, and Fees
The maximum 504 debenture is $5.5 million.4U.S. Small Business Administration. 504 Loans That’s separate from the third-party lender’s first-lien loan, so total project financing can be substantially larger.
Interest rates on the debenture portion are fixed for the life of the loan. They’re set at each monthly debenture sale based on the yield of comparable Treasury bonds (five-year Treasuries for 10-year terms, 10-year Treasuries for 20- and 25-year terms), plus a small fixed spread and an additional percentage covering ongoing annual fees. Because the rate locks at funding, 504 loans tend to offer more predictable long-term costs than adjustable-rate commercial mortgages.
Standard 504 fees include an upfront funding fee and an ongoing annual servicing fee built into the monthly payment. For small manufacturers, both are waived entirely during fiscal year 2026 (October 1, 2025 through September 30, 2026).5U.S. Small Business Administration. SBA Waives Loan Fees for Small Manufacturers in Fiscal Year 2026 Non-manufacturing borrowers should expect upfront fees in the range of 2.5% to 3.5% of the debenture amount, covering the SBA guarantee fee, CDC processing fee, and underwriting costs, plus a modest ongoing annual service fee.
Beyond SBA-specific fees, you pay for a commercial appraisal, title insurance, environmental review, legal fees, and any interim financing costs. A commercial real estate appraisal alone typically runs between $2,000 and $4,000, with higher prices in major metropolitan areas. Before the debenture is sold on the bond market, a third-party lender provides interim financing — essentially a short-term bridge loan covering the 504 portion. The interim loan is usually arranged by the bank providing the first-lien loan and typically carries a floating rate.
Job Creation or Retention
Every 504 project has to create or retain a certain number of jobs relative to the loan amount. The current standard is one job per $90,000 of SBA-guaranteed funding. Projects involving small manufacturers or those meeting energy-related public policy goals use a more relaxed ratio of one job per $140,000.6eCFR. 13 CFR 120.861 – Job Creation or Retention
For refinancing projects that don’t involve hiring, meeting the threshold often depends on demonstrating that existing jobs would be lost without the restructured financing. CDCs evaluate this retention argument as part of the economic justification, and it can become a sticking point for businesses that are stable but not growing.
Documentation You’ll Need
The package is substantial. Plan on providing:
- Federal tax returns for the operating company and any affiliated entities covering the previous three years.
- Year-to-date profit and loss statements and a balance sheet dated within 90 days of application.
- A debt schedule listing every current business obligation, with creditor names, balances, payment amounts, and maturity dates.
- A Personal Financial Statement (SBA Form 413) from every owner holding 20% or more of the business, covering personal assets and liabilities.7U.S. Small Business Administration. Personal Financial Statement
- An independent commercial appraisal of the real estate or equipment securing the refinance. The appraiser must be state-licensed or state-certified; for properties valued over $1 million, state certification is required. The appraisal must comply with the Uniform Standards of Professional Appraisal Practice (USPAP).
If the business operates as a franchise, it must appear in the SBA Franchise Directory. Brands that meet the FTC’s definition of a franchise are ineligible for any SBA financing unless they’re listed there.8U.S. Small Business Administration. SBA Franchise Directory Submitting false information on SBA documents is a federal crime under 18 U.S.C. § 1001.9Office of the Law Revision Counsel. 18 USC 1001 – Statements or Entries Generally
How the Application Moves
The entire package goes to a Certified Development Company, which acts as the intermediary between you and the SBA. The CDC reviews the documentation, underwrites the loan, and prepares the federal submission. Most of the back-and-forth happens here — CDCs frequently return applications for missing documents or incomplete financial data before anything moves to the SBA.
Once the CDC is satisfied, the package goes to the SBA’s Sacramento Loan Processing Center for final review and approval.10U.S. Small Business Administration. Sacramento Loan Processing Center If approved, the SBA issues a Loan Authorization that specifies the exact terms: interest rate, maturity, pre-closing conditions, and any special requirements. Read this document carefully rather than relying on summaries from the CDC or lender. It’s the binding agreement.
After the Loan Authorization is issued, closing involves signing the promissory notes, recording liens against the business assets, and coordinating interim financing until the debenture sells. The timeline from initial CDC submission to funded loan typically runs 45 to 90 days, though complex projects or incomplete documentation can stretch that significantly.
Paying Off an Existing 504 Loan
The other scenario works in the opposite direction: you already have a 504 loan and want to pay it off and move to conventional financing or an SBA 7(a) loan. This is governed by 13 CFR § 120.940, which permits prepayment of the full principal balance along with any unpaid interest, outstanding fees, and a prepayment premium.11eCFR. 13 CFR 120.940 – Prepayment of the 504 Loan or Debenture
The prepayment premium is where this gets expensive. It starts at the loan’s full debenture interest rate and declines by roughly 10% per year. On a 20- or 25-year loan, the premium disappears entirely after year 10. On a 10-year loan, it drops to zero after year five. A borrower with a 6% debenture rate who prepays in year one owes approximately 6% of the remaining principal as a penalty. By year five, that drops to about 3%. Prepaying during the second half of the term costs nothing beyond the outstanding balance and accrued interest.
Because 504 loans are funded through debenture pools sold to investors, the payoff has to be coordinated with the semi-annual debenture payment dates tied to the loan’s original funding date. You pay interest and servicing fees through the next scheduled debenture date. Miss the window and you wait up to six months for the next eligible payoff date, with interest continuing to accrue the whole time.
The payoff is processed through the Central Servicing Agent, which calculates the exact amount owed including the premium. Once payment clears, the SBA releases its lien on the business assets, freeing the collateral for the new lender to take a first-lien position. Coordinating timing between the new lender’s closing and the debenture payment date is the part most borrowers underestimate. Start the conversation with both lenders well before you need the money to move.
