SBA 504 vs. Commercial Mortgage in 2026: Which Wins for Owner-Occupied Real Estate

Business owners purchasing commercial real estate have two primary financing paths: SBA 504 loans and conventional commercial mortgages. Both serve owner-occupied properties, but the structures are fundamentally different in terms of down payment, fixed rate terms, and qualifying criteria. MLOs who understand both can add significant value to small business owner clients who often do not know the SBA 504 program exists.

SBA 504 Program Structure

The SBA 504 program uses a three-party structure. A conventional lender provides 50% of the project cost in a first lien position. A Certified Development Company provides 40% in a second lien position, funded by an SBA debenture. The borrower provides 10% down payment. This 10% down is the primary draw of the program for business owners who want to preserve working capital. The CDC portion carries a fixed rate tied to 10-year Treasury rates with a 10 or 20-year term. The bank first is typically variable or has a shorter fixed period.

Conventional Commercial Mortgage Structure

• ✦Conventional commercial mortgages typically require 25% to 30% down for owner-occupied properties
• ✦Terms are typically 5 to 10-year fixed with 20 to 25-year amortization and a balloon at maturity
• ✦No SBA eligibility requirements; foreign nationals, passive investors, and business owners with prior SBA defaults can qualify on the lender's own criteria
• ✦Faster to close than SBA 504; conventional commercial closes in 30 to 60 days versus 60 to 90 days for SBA 504

When SBA 504 Wins

SBA 504 wins when the business owner needs to conserve capital. A $1 million property requires only $100,000 down versus $250,000 on a conventional commercial mortgage. The CDC portion carries a fully amortizing fixed rate for 10 or 20 years -- no balloon risk on that piece. For businesses expanding into owned real estate for the first time, this is often the deciding factor. The trade-off is the longer closing timeline and the SBA eligibility and use-of-proceeds requirements.
