SBA 504 vs. Conventional Financing: When Does 504 Make More Sense?

When a business is ready to purchase a building, construct a new facility, or invest in major equipment, one of the biggest financing decisions is choosing the right loan structure.

For many established businesses, conventional financing may be the obvious starting point. But an SBA 504 loan can offer a compelling alternative—particularly when the project involves significant fixed assets and the business wants to preserve cash for operations and growth.

So, when does SBA 504 make more sense than conventional financing?

What Is an SBA 504 Loan?

The SBA 504 Loan Program provides long-term, fixed-rate financing for major fixed assets that support business growth and job creation. The program is delivered through Certified Development Companies (CDCs) in partnership with private-sector lenders.

Eligible uses can include purchasing or constructing commercial real estate, improving existing facilities, and purchasing certain long-term machinery and equipment. SBA 504 can also be used for certain eligible debt refinancing.

One of the key differences from conventional financing is the way a typical 504 project is structured.

·         Up to 50% from the private-sector lender

·         Up to 40% from the CDC/SBA 504 loan

·         At least 10% borrower equity

The exact structure can vary depending on the project and borrower circumstances. That structure can create an opportunity for a business to acquire a major fixed asset while keeping more of its capital available for working capital, hiring, inventory, marketing, and other business needs.

1. When Preserving Cash Is Important

One of the biggest advantages of considering SBA 504 is the potential to reduce the amount of cash a business needs to put into a project compared with some conventional financing structures.

That can leave more capital available for working capital, hiring, inventory, marketing, and other business needs.

2. When Long-Term, Fixed-Rate Financing Is Valuable

SBA 504 financing is designed to provide long-term, fixed-rate financing for major fixed assets.

The program currently offers 10-, 20-, and 25-year maturity terms, depending on the project and financing structure.

For a business making a large investment in a building or equipment, predictable long-term debt service can make financial planning easier.

3. When the Project Is Primarily Real Estate or Equipment

SBA 504 is particularly well suited to projects involving major fixed assets. Examples include:

·         Purchasing an owner-occupied commercial building

·         Constructing a new facility

·         Renovating or modernizing an existing facility

·         Financing certain long-term machinery and equipment

·         Expanding an existing business location

4. When a Business Wants to Keep Its Bank Relationship

SBA 504 does not replace the bank or conventional lender. The private-sector lender typically provides the first mortgage and holds the senior lien on the project.

This creates a partnership between the lender, CDC, and borrower. For banks, that can mean an opportunity to participate in larger commercial real estate transactions while maintaining a strong first-lien position.

5. When the Business Is Growing

The 504 program is designed around economic development, business growth, and investment in fixed assets.

A company purchasing a larger facility, expanding its production capacity, or investing in new equipment may be able to use 504 financing as part of a broader growth strategy.

In 2026, SBA has expanded the ability for eligible borrowers to combine 7(a) and 504 financing, allowing up to $10 million in combined SBA-backed financing under the new policy. Check current SBA guidance for applicable requirements.

The Bottom Line

If your business is purchasing commercial real estate, constructing a facility, expanding an existing location, or investing in major equipment, it may be worth comparing an SBA 504 structure alongside your conventional financing options.

A conversation with your lender and an experienced Certified Development Company early in the process can help determine whether 504 is a good fit.
