SBA 504 loans are purpose-built for owner-occupied commercial real estate: long amortization, a fixed rate on the SBA portion, and lower down payments than conventional commercial mortgages. SBA 7(a) covers real estate within a broader project loan. Conventional commercial mortgages apply when SBA eligibility doesn't fit.
The SBA 504 program is purpose-built for fixed assets — primarily owner-occupied commercial real estate and major equipment. The structure is a first-mortgage lender covering roughly half the project cost, a Certified Development Company (CDC) funding up to 40% (the SBA-guaranteed portion at a fixed rate), and the borrower contributing at least 10%. That 10% down payment is significantly lower than a conventional commercial mortgage, and the fixed-rate SBA tranche protects against rate increases over a long amortization period — commonly 20 to 25 years for real estate.
When real estate is part of a larger financing need — alongside equipment, working capital, or a business acquisition — SBA 7(a) bundles all those uses in a single loan with long terms and competitive rates. SBA 7(a) real estate loans can amortize up to 25 years. The trade-off versus 504 is that 7(a) rates are typically variable (tied to the prime rate), while the 504 SBA debenture carries a fixed rate — a meaningful difference over a 20-year hold.
Conventional commercial mortgages are the path when SBA eligibility doesn't apply: investment properties (SBA requires owner-occupancy), large loans above SBA program limits, or borrowers who prefer not to navigate SBA documentation. Conventional terms are typically shorter amortization with balloon payments at 5 to 10 years, and down payments of 25% to 35% are common. For most owner-occupants purchasing a first commercial property, SBA 504 or 7(a) will outperform conventional on both down payment and rate structure.
A dental practice paying $7,500/month in rent wants to purchase a 4,000 sq ft office building for $900,000. An SBA 504 loan matched through ClearValue Lending structures the deal with a 10% down payment ($90,000), a first-mortgage lender, and a CDC debenture — converting a rent expense into a fixed monthly ownership cost. The owner applies once at ClearValue Lending and is routed to a single matched lender. Estimate your monthly payment first with our business loan calculator.
