Yes. A 504 can refinance debt on owner-occupied commercial real estate and long-life equipment, either as part of an expansion project or on its own. The business must occupy at least 51% of an existing building. The debt must have paid for those fixed assets, be seasoned and have been paid as agreed, and SBA caps the refinance against the property's appraised value. A refinance without expansion can include only a limited amount for eligible business expenses; it is not a way to pay off unrelated lenders or take cash out to the owners.

Two kinds of 504 refinance
The 504 program was built to finance buildings and heavy equipment that a business uses itself: a bank lends the first mortgage, a Certified Development Company (CDC) lends a second funded by an SBA-guaranteed debenture, and the borrower puts in the rest. On a purchase the split is typically 50% from the bank, 40% from the CDC and 10% from the borrower. The same structure can refinance existing debt, in two ways.
| Refinance with expansion | Refinance without expansion | |
|---|---|---|
| When it applies | The business is buying, building or improving fixed assets, and wants to fold existing debt on its premises into the same project | The business wants to refinance existing debt on fixed assets it already owns, with no new project |
| What can be refinanced | Existing debt on the fixed assets, as part of a larger project | Qualified debt: debt that was used to acquire or improve eligible fixed assets |
| Room for other costs | The project's own costs | A limited allowance for eligible business expenses, capped relative to the property's value |
| Main conditions | The expansion must be a real 504 project; occupancy and job or public-policy goals apply | The debt must be seasoned and paid as agreed, and the refinance is capped against appraised value |
| Owner's contribution | The usual injection for the project | Usually the existing equity in the property |
Most owners asking this question want the second kind: the building is already theirs, the mortgage is expensive or short, and they want it on terms that match the life of the asset. That is a refinance without expansion, and the rest of this page is mostly about it.
Owner-occupancy
The 504 finances real estate the business uses, not investment property. For an existing building, the business must occupy at least 51% of it; for new construction the threshold is 60%. The remainder can be leased to tenants, and rent from them can help the numbers, but the operating business has to be the building's main user.
The common structure is a real estate company that owns the building and leases it to the operating company, with the same owners. SBA allows this through an eligible passive company: the property company borrows, the operating company guarantees, and the lease runs at least as long as the loan. Owners who have held the building in a separate entity for years usually need to tidy the lease and confirm the ownership lines up before a CDC will proceed. For the wider question of holding property separately, see propco and opco structures.
Occupancy is measured on the building's rentable space. A business that has shrunk into a corner of its own building may no longer qualify, however long it has owned it.
What debt qualifies, and the limits
A refinance without expansion is narrower than owners expect. It is for debt that built or bought the fixed assets, not for everything the business owes.
- Qualified debt. The debt being refinanced must have been used to acquire or improve eligible fixed assets, and the lender traces what it paid for. A mortgage on the building qualifies; an equipment note on long-life equipment can; a working capital line secured by the building usually does not, because of what it funded.
- Seasoning and payment history. The debt must have been in place for a minimum period before the application and paid as agreed. A mortgage that is behind is not a 504 candidate.
- A loan-to-value cap. SBA caps the refinance against the property's appraised value, so the owner's equity in the building effectively serves as the borrower's contribution. A building that has not appreciated, or that carries heavy existing debt, may not leave room for a meaningful refinance.
- Eligible business expenses. The refinance can include a limited amount for operating expenses of the business, such as payroll, utilities or inventory. That allowance is capped and must be documented; it is not a general fund for retiring other lenders.
- No cash to the owners. SBA loan proceeds cannot fund a distribution to owners, or refinance debt that did. A 504 refinance is not a cash-out refinance.
Debts outside this list — term loans, lines of credit, credit cards — are for a 7(a) refinance or a conventional lender. Active cash advances are outside both SBA programs and need a different route first. Since July 2026 the 504 and 7(a) limits are counted separately, so a business can use a 504 on its building and a 7(a) on its other debt without one crowding out the other. How the two programs compare generally is on 7(a) vs 504.
When moving the real estate changes the whole capital structure
The most useful 504 refinances are not about the building. They are about what the building's payment has been doing to everything else.
Many owner-occupied buildings are financed with bank mortgages on short terms and balloons, or with amortizations far shorter than the life of the asset. The payment is high, and every few years the business has to refinance a balloon. Meanwhile the operating debt — a term loan, a line, equipment — is tested against earnings that the mortgage payment has already consumed. Put the building on a long 504 schedule and the freed cash flow shows up in the coverage test for everything else.
| Today | After a 504 refinance of the building | |
|---|---|---|
| Earnings before debt payments (EBITDA) | 1,000 | 1,000 |
| Building mortgage payments over a year | 350 on a short amortization with a balloon | About 220 on a long, fixed schedule |
| Operating debt payments over a year | 550 | 550 |
| Total debt payments | 900 | 770 |
| Left after debt payments | 100: barely covered | 230: comfortably covered |
On the left, the business is below the coverage most lenders will accept; conventional bank lenders commonly look for at least 1.25x. On the right, it clears that line. The operating company can now refinance its term loan on better terms, renew a line that was under review, or carry equipment for growth, none of which the numbers supported while the building payment sat at 350. That is the question to ask before a 504 refinance: not just "will this lower the mortgage payment" but "what does the lower payment let us do with the rest of the stack."
It also works in reverse. If the building payment is already reasonable, a 504 may save less than the cost and effort of doing it, and the answer lies elsewhere: see the refinance break-even and how much debt a business can carry.
504 against the alternatives
| Route | What it offers | What to weigh |
|---|---|---|
| 504 refinance | Long, fixed terms on the CDC share; the bank share on its own terms | Occupancy, the value cap, a two-lender closing, and the CDC's own prepayment terms |
| 7(a) with real estate | Up to 25 years on the real estate share; can include other business debt in one loan | Priced under SBA's 7(a) rate caps, commonly variable, rather than on a fixed debenture; counts against the 7(a) limit |
| Conventional commercial mortgage | One lender, fewer program rules | Shorter terms and balloons are common; see 504 vs a conventional mortgage |
| Sale-leaseback | Turns the building's equity into cash | The business becomes a tenant; see sale-leasebacks |
The 504's strength is predictability: a fixed payment on a large share of the building for a long time. Its weakness is flexibility. Two lenders, SBA's program rules and prepayment terms make it a structure to hold rather than to trade out of quickly. See how prepayment penalties work.
What the file needs
A 504 refinance is underwritten twice, once by the bank and once by the CDC, on the same documents:
- Business tax returns for two to three years, the P&L and balance sheet, and a year-to-date P&L through last month-end.
- A debt schedule with a copy of every note being refinanced, showing what each debt originally financed and its payment history. The qualified-debt test is run from it. See how to prepare a debt schedule.
- Personal tax returns for two to three years and a personal financial statement for each owner of 20% or more, each of whom guarantees the loan.
- The lease between the property company and the operating company, and a floor plan or rent roll that shows occupancy.
- An appraisal and an environmental review of the property, ordered by the lenders.
- Documentation of any eligible business expenses to be included.
Once the documents are in, Transparent builds the lender package — financing model, lender presentation, blind teaser and underwriting memo — in a day. The model shows the building's payment before and after and runs the coverage on the whole capital structure, so the bank and CDC see what the refinance does for the business, not just the property. 278 lenders in Transparent's book write SBA 7(a) and 504. Transparent charges nothing before a loan closes, and on SBA loans the lender pays Transparent, not the borrower.
Common questions
- Can a 504 refinance pay off my line of credit or credit cards?
- Generally not as debt refinancing, because those debts did not buy fixed assets. A refinance without expansion can include a limited, documented amount for eligible business expenses, but it is capped. A 7(a) refinance is the usual route for other business debt.
- Can I take cash out of my building with a 504?
- No. SBA loan proceeds cannot fund a distribution to owners. Owners who want to turn the building's equity into cash look at a conventional cash-out refinance or a sale-leaseback; see sale-leaseback vs cash-out refinance.
- Does it matter that the building is owned by a separate company?
- Not if it is set up properly. The property company can borrow as an eligible passive company, leasing to the operating company, which guarantees the loan. The lease and ownership have to line up with SBA's rules before closing.
- Our business uses about half the building. Does it qualify?
- For an existing building the business must occupy at least 51%. Occupancy is measured on rentable space, so the CDC will want a floor plan or rent roll showing it.
- If I already have a 7(a) loan, can I still use a 504 on my building?
- Yes. Since July 2026 the 504 and 7(a) limits are counted separately, so one does not use up room under the other. The business still has to carry both payments in the coverage test.
