What is the minimum down payment for an SBA 504 loan on commercial real estate?

Most SBA 504 loans require a 10% down payment from the borrower. The structure splits the remaining 90% between a conventional first mortgage (typically 50% of the project cost, from a bank or credit union) and a CDC second mortgage funded by the SBA (up to 40%). For special-use properties or startups with less than two years in business, the down payment requirement may increase to 15% or 20%.

What types of commercial properties qualify for SBA 504 financing in Florida?

Owner-occupied commercial properties qualify — meaning the business purchasing the property must occupy at least 51% of the usable space. Eligible property types include office buildings, retail storefronts, warehouse and industrial facilities, medical and dental offices, auto repair shops, restaurants (the building, not just the business), and light manufacturing facilities. The property must be used by the operating business, not held purely as an investment.

How do SBA 504 interest rates compare to conventional commercial loans in 2026?

SBA 504 rates are pegged to the 10-year U.S. Treasury and are fixed for the full term of the loan. In mid-2026, 504 debenture rates are running in the 5% to 7% range depending on term and project type — generally below conventional commercial mortgage rates, which are ranging from about 6.5% to 8.5% for similar owner-occupied assets. The fixed rate is a key advantage: conventional commercial mortgages typically have 5- to 10-year balloon resets, while the SBA 504 second mortgage carries a 20- or 25-year fixed term.

How long does it take to close an SBA 504 loan in Florida?

The SBA 504 process typically takes 60 to 90 days from application to close, though well-prepared borrowers with clean financials can sometimes close in 45 to 60 days. The process involves both a conventional lender (for the first mortgage) and a Certified Development Company (CDC) for the SBA portion. Getting your financials organized early — three years of business tax returns, personal financial statements, a business plan for newer businesses, and property details — is the biggest factor in keeping the timeline on track.

Is an SBA 7(a) or SBA 504 loan better for buying commercial real estate?

For purchasing commercial real estate, the SBA 504 is usually the better choice. The 504 offers lower fixed rates, longer terms (20–25 years on the SBA portion), and higher loan amounts on the real estate component. The SBA 7(a) is more flexible — it can be used for working capital, equipment, and real estate together — but it typically carries a variable rate tied to prime and has a maximum loan size of $5 million. If the primary goal is acquiring a building, the 504 structure delivers lower monthly payments and rate certainty.

SBA 504 Loans for Commercial Real Estate in Tampa Bay

Renting commercial space in Tampa Bay has become increasingly expensive, and availability at attractive price points is shrinking — retail vacancy sits near a historic low of 3.8% as of mid-2026. For business owners who have been writing rent checks for years, the question is no longer whether to look at ownership, but how to finance it. The SBA 504 loan is the most powerful tool available, and Barrett Henry — with 23+ years of commercial real estate experience and a broker with REMAX Collective across Hillsborough, Pinellas, Pasco, and Manatee counties — works directly with business owners navigating this process.

What Is an SBA 504 Loan and How Does It Work?

The SBA 504 loan program is a government-backed financing tool designed specifically to help small businesses acquire major fixed assets — including commercial real estate. Unlike a conventional mortgage where one lender provides the full loan, the 504 program uses a three-party structure:

The borrower contributes 10% of the total project cost as a down payment (in most cases).
A conventional lender (bank, credit union, or private lender) provides a first mortgage covering roughly 50% of the project cost.
A Certified Development Company (CDC), backed by the SBA, issues a second mortgage covering up to 40% of the cost through a fixed-rate 20- or 25-year debenture.

The result: a business owner can acquire a commercial property with a fraction of the capital required for a conventional purchase, locking in long-term fixed rates on the SBA portion. In a market where conventional commercial loans often require 25% to 35% down and carry variable rates with 5- to 10-year balloon resets, the 504 structure is a meaningful advantage.

The SBA 504 loan splits financing across three parties — the borrower, a conventional lender, and the SBA — enabling owner-users to acquire commercial real estate with 10% down and long-term fixed rates.

What Properties Qualify for SBA 504 Financing in Tampa Bay?

The core requirement is owner-occupancy: the purchasing business must occupy at least 51% of the rentable square footage (or 60% in the case of new construction, with plans to occupy more over time). This rules out pure investment properties, but it covers a wide range of commercial asset types that Tampa Bay business owners routinely purchase:

Office buildings. Medical, dental, legal, financial advisory, and professional services firms frequently buy their own buildings using 504 financing. Tampa Bay's suburban office market — particularly in Hillsborough and Wesley Chapel — has been actively targeted by owner-users.
Retail storefronts and strip center bays. Restaurants, salons, fitness studios, and specialty retailers buying their locations. If you have been leasing a strip center bay for years, the SBA 504 lets you buy comparable space and build equity instead.
Warehouse and industrial. Contractors, distributors, light manufacturers, and trades businesses buying their own shop and storage space. Tampa Bay's industrial market remains supply-constrained, making ownership attractive for established operators. See our Tampa industrial market outlook for context on current conditions.
Medical and dental offices. Healthcare practices are among the most active owner-users in the SBA 504 program. Read our Tampa Bay medical office guide for more on this sector.
Auto service, light manufacturing, and special-use. These work but may carry a higher down payment (15–20%) depending on the lender's assessment of the property's resale utility.

What Are SBA 504 Rates in Mid-2026?

SBA 504 debenture rates are set monthly based on the 10-year U.S. Treasury rate and are fixed for the life of the loan. In mid-2026, the 504 debenture rate for a 20-year term is running in the 5.5% to 6.5% range — modestly higher than the 2021–2022 historic lows but competitive against conventional commercial mortgage alternatives.

The conventional first mortgage portion (typically 50% of project cost) carries a rate set by the bank — usually ranging from 6.5% to 8% for strong borrowers in today's environment. The blended effective rate on the combined first and second mortgage tends to land meaningfully below a conventional stand-alone commercial mortgage at the same loan-to-value.

Perhaps more important than the rate itself is the term. The SBA 504 second mortgage is fixed for 20 or 25 years — there is no balloon payment, no refinancing risk, and no rate reset. For a business owner who plans to occupy a building for a decade or more, that certainty has real value.

Owner-occupied commercial real estate builds equity in an asset that also houses your business — a dual benefit that pure rent payments never provide.

Why Are Tampa Bay Business Owners Choosing to Buy Right Now?

Several market conditions are converging to make ownership more attractive than leasing for established Tampa Bay businesses:

Lease rates are rising. Tampa Bay retail vacancy near 3.8% means landlords hold negotiating leverage. Lease renewals are coming in higher, and tenant improvement allowances have tightened. Locking in an ownership cost now protects against continued rent escalation.
Equity accumulation. Every mortgage payment builds equity in an asset. After 10 to 15 years, a business owner who bought is sitting on a significant asset — one that can be refinanced, sold, or leased back at retirement.
Operational control. Owners are not subject to landlord decisions about the property — no lease renewal uncertainty, no restrictions on signage, build-out, or hours.
Tax advantages. Depreciation on the building, interest deductions, and potential Section 179 deductions on equipment purchased alongside the real estate all reduce the net after-tax cost of ownership.
The sale-leaseback option. Some business owners purchase a building, occupy it initially, and later sell it to an investor with a long-term leaseback -- converting their equity to capital while staying put. If you are considering selling your current location to access equity before purchasing a new owner-occupied building, contact Barrett to discuss your options through the dispositions process.

What Does the SBA 504 Application Process Look Like?

The process involves two parallel tracks — the conventional lender for the first mortgage and the CDC for the SBA second. Here is what to expect:

Pre-qualification. Before you start seriously shopping for a property, get pre-qualified with both a lender experienced in SBA 504 deals and a CDC active in Florida. This tells you your purchase price range and identifies any business or personal financial issues to address early.
Property identification. Work with a commercial real estate broker to identify qualified owner-user properties. Barrett helps clients find buildings that fit their operational needs, qualify under SBA rules, and make financial sense at current prices. Use our ROI calculators to stress-test purchase scenarios before making offers.
Due diligence and appraisal. Both the conventional lender and the CDC will require appraisals and Phase I environmental assessments. The due diligence timeline for an SBA-financed deal typically runs 45 to 60 days — build this into your contract contingency period.
SBA credit review. The SBA reviews the borrower's business financial statements, projections, and the overall deal structure. Having three years of clean business tax returns and a coherent narrative about how the building serves the business makes this review go faster.
Closing. The conventional first mortgage and the SBA second mortgage fund simultaneously at closing. Total time from accepted offer to close is typically 60 to 90 days for prepared borrowers.

Commercial real estate office building in Tampa Bay available for owner-user SBA 504 purchase

Owner-user commercial properties across Tampa Bay — from suburban office to warehouse and retail — are actively available for qualified SBA 504 buyers. Working with a broker who knows the owner-user segment is essential in a tight market.

Common Mistakes Tampa Bay Buyers Make With SBA 504 Loans

Starting the process too late. The SBA 504 process takes time. Business owners who begin lender conversations after signing a purchase agreement often run out of contingency time. Start pre-qualification before you start actively searching.
Underestimating project costs. The SBA 504 covers the real estate acquisition, but also eligible soft costs — appraisals, environmental assessments, title, legal fees, and some closing costs. Make sure your project cost estimate is comprehensive so the loan sizing is correct.
Choosing a lender without SBA 504 experience. Not every bank closes SBA 504 loans regularly. Work with a preferred lender — one that the SBA has approved to make credit decisions in-house — to reduce processing time and friction.
Ignoring the occupancy requirement. If you plan to lease more than 49% of the building to other tenants immediately after purchase, the property will not qualify for 504 financing. The program is for owner-occupants, not investors. If you are buying a larger building with tenants already in place, work with your attorney and broker to structure the occupancy correctly.
Not accounting for property insurance. Florida's property insurance market is expensive and improving slowly. Get real insurance quotes as part of your due diligence — not estimates. This affects your operating cost analysis significantly. See our Florida insurance crisis overview for the current landscape.

The Bottom Line

The SBA 504 loan program is one of the most effective tools available for Tampa Bay business owners who want to stop renting and start building equity in their own commercial space. With as little as 10% down, fixed long-term rates, and loan amounts that accommodate the full range of commercial property sizes in this market, it opens ownership to businesses that would otherwise be priced out of conventional financing. Barrett Henry has helped business owners across Tampa Bay identify qualified owner-user properties, structure offers that work within SBA timelines, and close on buildings that serve both their operational needs and their financial goals.
