When your business outgrows its lease, buying a building can protect your location and build equity. However, a large commercial down payment can drain cash needed for payroll, inventory, or equipment.
Understanding SBA 504 loan requirements before you sign a letter of intent helps you avoid buying a property that doesn’t fit the program. The U.S. Small Business Administration (SBA) 504 program supports established operating businesses seeking long-term financing. It funds owner-occupied commercial real estate and other major fixed assets.
The strongest applications match the borrower, the property, and the repayment plan from the start.

Key Takeaways
- SBA 504 loans combine a conventional first mortgage, a CDC-backed second mortgage, and a borrower contribution to finance owner-occupied commercial real estate and other major fixed assets.
- The operating business must be for-profit, located in the United States, small under SBA standards, and generally occupy at least 51% of an existing building or 60% of a new construction project initially.
- Most qualified projects require a 10% borrower contribution, while startups and special-purpose properties may require 15% to 20% or more.
- Eligible uses include commercial property, construction, renovations, and long-life equipment; inventory, payroll, advertising, and routine operating expenses are not eligible.
- Borrowers should prepare financial records, ownership documents, projections, property details, and proof of funds before making a binding offer, then continue tracking occupancy, insurance, taxes, and other loan covenants after closing.
How the SBA 504 financing structure works
The SBA 504 loan program combines three funding sources for one commercial real estate or equipment project. A conventional lender provides the first mortgage, a Certified Development Company provides an SBA-backed second mortgage, and the borrower makes an equity contribution.
The SBA’s official 504 program overview confirms that the program is for long-term projects involving fixed assets. It is not a source of general operating cash.
| Funding source | Typical share of total project cost | Role in the transaction |
|---|---|---|
| Conventional lender | 50% | Provides the senior loan, usually secured by a first lien |
| Certified Development Company | 40% | Provides the SBA-backed debenture, usually secured by a second lien |
| Borrower | 10% or more | Provides the required cash injection or eligible equity |
The CDC portion can provide fixed-rate financing, while the first mortgage may have different pricing.
For example, a $2 million owner-occupied building purchase might use a $1 million bank loan, an $800,000 CDC loan, and a $200,000 borrower contribution. Closing costs, lender fees, and project reserves can affect the final figures.
The 50-40-10 structure is a starting point, not an automatic approval. The bank still reviews repayment ability, collateral, management experience, and the strength of the project.
The CDC and first-mortgage lender both underwrite the transaction. SBA support does not remove the need for reliable business cash flow.
Certified Development Companies guide the SBA portion of the deal and coordinate with the lender. The SBA’s 504 Loan Program Factsheet is a useful reference for the program’s purpose and high-level terms.
SBA 504 loan requirements: borrower, property, and project
These eligibility criteria extend beyond credit and revenue. The SBA reviews the operating business, its owners, affiliates, financial history, property use, and expected public benefit.
The business must meet SBA eligibility standards
Your company must be a for-profit operating business located in the United States. Passive real estate investors cannot use a 504 loan to buy property simply to lease it to unrelated tenants.
The business must also qualify as small under SBA size standards. Many borrowers use the SBA’s alternative size test, which requires:
- Tangible net worth of no more than $15 million.
- Average net income after federal income taxes of no more than $5 million during the previous two full fiscal years.
The SBA may include affiliated businesses when reviewing size and financial capacity. Ownership structures matter, especially when one owner controls several companies or real estate entities.
Personal credit is not the sole approval factor. Still, owners with 20% or more ownership normally provide personal guarantees. Lenders also want a manageable debt schedule, consistent financial reporting, and enough cash flow to cover the proposed payment.
Owner occupancy rules protect the program’s purpose
The property must support your own operating company. For an existing building, the operating business generally must occupy at least 51% of the rentable space.
For new construction, the business must initially occupy at least 60% of the space. It must plan to occupy at least 80% within 10 years. You can lease the remaining eligible space to tenants, but rental income cannot become the project’s main purpose.
Many businesses hold the building in a separate real estate entity, often called an Eligible Passive Company. This structure can work when the property entity leases the space to the operating company. The CDC will require the entities to remain connected through the lease, guarantees, and loan documents.
The project must also meet a job creation or public-policy goal. Document the applicable job creation benchmark, such as one job created or retained for every $90,000 of CDC financing, or every $140,000 for qualifying small manufacturers. Projects that advance goals such as rural development, energy efficiency, or revitalization may qualify through another public-policy standard.
Eligible fixed assets and project costs
An SBA 504 loan finances assets that hold value and support operations for many years. Commercial real estate is the most common use, but the program also supports heavy equipment and other major equipment purchases.
Eligible project costs can include an existing office, warehouse, medical facility, retail location, or manufacturing plant. Land may also qualify when the project includes construction or planned development.
Ground-up construction, major renovations, parking, landscaping, utilities, and site work may qualify. Long-life machinery and equipment can qualify when they have an expected useful life of at least 10 years.
The program also supports restaurant equipment financing when the purchase involves durable kitchen equipment, refrigeration systems, or long-lived improvements. A healthcare practice may use it to buy a medical office or install qualifying diagnostic equipment.
An SBA 504 loan cannot pay for inventory, advertising, payroll, accounts payable, or routine operating expenses. It also cannot finance a speculative property purchase. Certain qualified commercial debt refinancing projects may be eligible, but the rules are narrower and require CDC review.
A contractor can use a 504 loan to buy a yard, shop, or equipment-heavy facility. An e-commerce company can use it for a warehouse it occupies. A retailer can purchase its longtime storefront when the occupancy test is met.
Down payment rules for startups and limited-use properties
Most qualified projects begin with a 10% borrower contribution. Startups and purpose-built properties often need more equity because they carry greater underwriting risk.
| Project type | Typical minimum borrower contribution |
|---|---|
| Established business and standard property | 10% |
| Startup business | 15% |
| Purpose-built property | 15% |
| Startup business buying a purpose-built property | 20% |
For 504 purposes, a startup is generally a business that has operated for less than two years. A special purpose property is a building designed for limited use, such as a hotel, assisted-living facility, bowling center, car wash, or similar operation.
The lender can require more than the SBA minimum. A weak debt-service coverage ratio, thin reserves, or a complex construction budget can increase the required cash injection.
Startup businesses can obtain an SBA 504 construction loan. They need a detailed business plan, owner experience, financial projections, contractor bids, permits, and enough liquidity to manage construction delays. Signed customer contracts can strengthen a contractor’s file, while a physician’s established patient base can support a new practice location.
For every borrower, the cash contribution needs to be documented. Keep bank statements, proof of source, and records for any gift, asset sale, or equity transfer that forms part of the injection.
SBA 504 rates, terms, and loan limits in 2026
A 504 transaction has two loans, so it doesn’t have one universal interest rate. The CDC debenture portion generally provides fixed-rate financing, while the conventional lender sets terms and pricing for its first mortgage.
CDC financing commonly offers 10-year, 20-year, or 25-year repayment terms. In 2026, published CDC effective rates have generally ranged from the mid-5% range to the low-6% range, depending on the term and monthly bond market pricing.
The first-mortgage lender may offer fixed or variable pricing. Compare interest rates across the complete capital stack instead of focusing only on the CDC rate. Review amortization, lender fees, prepayment terms, projected payment changes, and whether construction interest is included.
The standard SBA 504 loan amount for the CDC debenture is capped at $5 million. It can reach $5.5 million for qualifying small manufacturers and certain energy or public-policy projects.
In May 2026, the SBA announced that eligible borrowers could combine up to $5 million in 7(a) financing with up to $5 million in 504 financing, for up to $10 million in combined SBA-backed financing. Review the SBA’s May 2026 loan-limit update with your CDC, and confirm current rates, limits, and eligibility if your expansion requires more than one SBA program.
Build a complete application file before you make an offer
A clean package saves time because the conventional lender and CDC need to validate the same story. The CDC can also help you identify a participating lender. The SBA outlines lender participation standards for institutions involved in SBA programs.
Start by defining the project budget. Include the purchase price, renovation work, equipment, closing costs, environmental reports, appraisal costs, and contingency funds. A low purchase price won’t help if the building needs major repairs your budget missed.
Then gather the records your lender will request:
- Three years of business federal tax returns, if available.
- Current year-to-date profit and loss statements and balance sheets.
- Three years of personal tax returns for principal owners.
- A personal financial statement and complete business debt schedule.
- Entity documents, ownership information, and resumes for key owners.
- A purchase agreement or letter of intent for the property.
- A business plan and projections, especially for startups or expansion projects.
- Construction plans, contractor bids, equipment quotes, and permits when applicable.
- A lease and occupancy calculation if a property-holding entity will own the building.
A typical application process has four stages:
- Meet with a CDC and lender to test eligibility, cash flow, occupancy, and projected equity requirements before signing a non-refundable contract.
- Submit financial records, project documents, ownership details, and a clear explanation of how the property supports revenue and operations.
- Complete appraisal, environmental review, title work, hazard insurance review, and construction due diligence when needed.
- Close the lender’s first mortgage and CDC financing. Track construction draws and occupancy milestones if the project involves new development.
A simple existing-building purchase may close in a few months. Construction projects commonly take longer because appraisal, permits, bidding, inspections, and draw schedules all need review.
Post-closing covenants that owners should track
Post-closing requirements continue beyond the closing date. The property must remain owner-occupied under the approved plan, and the business must keep operating as represented in its application.
Maintain hazard insurance and flood insurance when required. Keep property taxes current. The CDC or lender may request annual financial statements, business tax returns, insurance renewals, and confirmation of occupancy.
You also need written approval before making material changes. This can include transferring ownership, adding liens, changing the operating company, selling part of the property, or leasing more space than the program permits.
Owner occupancy is an ongoing loan covenant. It is not a one-time closing document.
Build these costs into your small business cash flow management routine. Property taxes, insurance, maintenance, and debt service should appear in the monthly forecast, not as surprises.
Keep permanent property financing separate from operating cash
An SBA 504 loan supports a long-lived asset. It isn’t designed for temporary shortfalls or payroll needs that require immediate liquidity.
A contractor waiting on project milestones may need a construction bridge or working capital for SMBs while a property transaction moves through underwriting. In that situation, working capital can help cover payroll and supplier costs without turning long-term real estate financing into a short-term liquidity tool.
Seasonal inventory purchases and e-commerce stock orders may require shorter-term financing before a holiday rush. Healthcare practice working capital can cover staffing or supplies between reimbursements. Service businesses may also need funding when client invoices arrive after payroll.
An unsecured business line of credit can provide a standby reserve when used with discipline. Review any offer carefully, including its repayment schedule, fees, and total cost, before committing.
Using outside capital to scale a business works best when the term matches the asset’s useful life. A building fits long-term SBA financing. Inventory, payroll, and supplier orders need shorter-term options.
Business credit programs can support future approvals through on-time payments, vendor reporting, and clean financial records. Building strong business credit takes consistent reporting and responsible use of capital, not shortcuts.
Alternative funding can help businesses manage immediate needs, even with modest monthly revenue. Established companies should define each use of funds and improve operating margins before taking on a property payment.

How much money must I put down for an SBA 504 loan?
Most qualified projects require a 10% borrower contribution. Startups and special-purpose properties commonly require 15%, while a startup purchasing a special-purpose property may need 20%; the lender or CDC can require more based on project risk.
Can I use an SBA 504 loan to buy any commercial property?
No. The property must support the borrower’s operating business and satisfy the SBA’s occupancy requirements. Passive real estate investments and speculative purchases are not eligible, although qualifying space may be leased to tenants.
What can an SBA 504 loan finance?
The program can finance commercial real estate, construction, renovations, site work, and durable equipment with a useful life of at least 10 years. It generally cannot finance inventory, payroll, advertising, accounts payable, or routine operating expenses.
What documents are needed for an SBA 504 application?
Lenders and CDCs typically request business and personal tax returns, current financial statements, a debt schedule, ownership documents, resumes, a purchase agreement, and business projections. Construction or equipment projects may also require plans, bids, permits, appraisals, environmental reports, and proof of the borrower’s equity contribution.
Build the project around the rules
A strong 504 application starts with the right building, documented financial records, and a realistic occupancy plan. The loan can create long-term stability, but only when the property supports the operations that repay it.
Review the program rules before making a binding offer, then bring the CDC and lender into the conversation early. Request a free financial consultation to review the capital structure behind your next owner-occupied property.
