At Thorne CRE, our wholesale SBA 504 lending desk helps mortgage brokers deliver long-term, fixed-rate financing to their clients. We give our partners dedicated support on first mortgages, flexible underwriting, and competitive compensation. It’s how we help them close commercial real estate transactions.
Key Takeaways for Commercial Mortgage Brokers
- Up to 90% Financing: Help your small business clients acquire, build, or refinance their owner-occupied real estate with as little as 10% down.
- Senior Mortgage Execution: Thorne CRE’s wholesale desk underwrites, prices, and funds that 50% first mortgage. We also handle coordinating with the CDC for the debenture.
- Protected Origination Fees: You can earn up to 1.00% on the senior note balance (that’s $25,000 on a $2.5M first loan), and we make sure it’s all clearly laid out on the closing statement.
- Accelerated Timelines: We get initial pre-flight term sheets out in 5 days. Full credit underwriting and funding? That usually happens in 30 to 45 days.
What is a Wholesale SBA 504 Lending Desk?
Commercial mortgage brokers often meet small and mid-sized business clients who want to buy, build, or refinance owner-occupied real estate. Conventional commercial bank financing often caps loan-to-value (LTV) ratios at 65% to 75%. That means a business owner has to pull a lot of cash equity out of their operating reserves. The Small Business Administration (SBA) 504 loan program, however, lets them finance up to 90%. Still, dealing with the institutional rules for that senior mortgage component can be a real headache for independent advisors.
A wholesale SBA 504 lending desk is basically an institutional primary capital partner built specifically for mortgage brokers, loan officers, and commercial real estate advisors. You won’t have to carry balance-sheet capital or juggle tricky execution processes across several regional lenders. Our wholesale desk specializes in underwriting, structuring, and funding that 50% first-lien conventional mortgage piece of the SBA 504 stack. At the same time, we coordinate the approval and closing of the 40% second-lien debenture with a regional Certified Development Company (CDC).
Working with our dedicated wholesale channel means commercial real estate professionals keep full control of their client relationships. We handle all the technical underwriting complexities, the debt service coverage ratio (DSCR) calculations, and the intercreditor agreements these government-backed lending programs require. This lets brokers expand their product offerings, protect their origination fees, and bring long-term capital to business owners.
Understanding the SBA 504 Capital Structure: The 50/40/10 Framework
The SBA 504 loan program uses a unique multi-layered capital structure. It’s designed to lower risk for senior lenders while giving business owners options with a low down payment. The standard framework splits financial responsibility among three different parties: a conventional senior lender, a Certified Development Company (which acts for the SBA), and the business owner.
- 50% First Mortgage (Senior Lender): Our wholesale desk or an institutional capital partner funds this directly. It’s the primary lien on the commercial property. You’ll find market-driven interest rates, flexible amortization schedules (typically 10 to 25 years), and loan terms built to match the borrower’s cash flow.
- 40% Second Mortgage (CDC / SBA Debenture): A local Certified Development Company manages this, and it’s 100% backed by an SBA-guaranteed debenture. This second lien offers a 10-year, 20-year, or 25-year fully fixed interest rate, usually priced at a small spread over 10-year U.S. Treasury yields.
- 10% Borrower Equity Contribution: The operating business or its owners provide this, either in cash or as eligible equity in real estate assets. This minimal down payment helps preserve working capital. Business owners can use it for day-to-day operations, buying inventory, or growing their payroll.
Worked Example: $5,000,000 Industrial Facility Acquisition
Let’s look at how our wholesale desk puts this structure together for your clients. Imagine a typical owner-occupied industrial warehouse purchase. An expanding precision manufacturing firm needs a dedicated facility to keep up with growing contract volumes.
| Capital Component | Funding Source | Percentage of Total | Dollar Amount | Terms & Pricing Mechanics |
|---|---|---|---|---|
| First Mortgage | Wholesale Lending Desk | 50% | $2,500,000 | 6.50% interest rate, 25-year amortization schedule, primary lien position |
| Second Mortgage | Certified Development Company (SBA Debenture) | 40% | $2,000,000 | Fixed debenture rate locked at pool closing, 25-year term, fully amortizing, secondary lien position |
| Borrower Equity | Operating Business Reserves | 10% | $500,000 | Verified liquidity or eligible land contribution |
| Total Project Cost | Combined Execution | 100% | $5,000,000 | Complete project acquisition and closing costs financing |
If this business owner went with a conventional commercial bank, they’d typically have to put down at least 25% to 35%. That’s between $1,250,000 and $1,750,000 in cash equity! Using our wholesale SBA 504 desk means the business owner saves up to $1,250,000 in upfront capital. Plus, the senior lender’s risk is lower because our first-mortgage exposure is capped at a conservative 50% LTV.
Modified Capital Structures: 50/35/15 Framework
Sometimes, commercial real estate transactions involve projects with a higher credit risk profile, according to SBA program rules. If you’re financing a single-purpose or specialized property – like a cold storage facility, a commercial car wash, or a specialized healthcare center – or if you’re backing a startup business (meaning it’s been operating for less than two years), SBA regulations require an extra 5% equity contribution.
In these cases, the capital structure changes to a 50/35/15 split:
- 50% First Mortgage: Our wholesale desk still handles this, keeping senior debt pricing consistent and loan balance metrics conservative.
- 35% CDC Debenture: This portion is reduced by 5% to account for the project’s classification.
- 15% Borrower Equity: The borrower provides this to ensure proper risk mitigation.
What if a project is *both* a special-use property *and* a startup business? Then the minimum equity contribution jumps to 20%, creating a 50/30/20 capital allocation. No matter the scenario, our wholesale desk keeps that primary 50% lien position, which means our underwriting parameters stay stable, regardless of how the property is classified.
SBA 504 vs. Conventional vs. SBA 7(a) Comparison
When you understand how the wholesale SBA 504 program stacks up against other commercial debt options, you can better position the right capital structure for your business clients.
| Feature / Metric | Wholesale SBA 504 Desk | Conventional Bank Loan | SBA 7(a) Loan |
|---|---|---|---|
| Max Loan / Project Size | No maximum project limit (Debenture up to $5.5M) | Varies by bank balance sheet | $5,000,000 total cap |
| Max Loan-to-Value (LTV) | Up to 90% (80–85% special use) | 65% – 75% LTV | Up to 90% LTV |
| Interest Rate Structure | 25-yr fixed debenture + competitive 1st note | 5–10 yr balloon / resetting fixed | Variable (SOFR / Prime + spread) |
| Broker Compensation | Up to 1.00% fee on senior mortgage | Varies, often capped or restricted | Strictly regulated broker fee limits |
| Use of Proceeds | Real estate, construction, heavy equipment | Real estate, equipment, refi | Working capital, real estate, M&A |
Benefits of Partnering with Thorne CRE’s Wholesale Desk
Independent mortgage brokers often hit big operational snags when they try to put together SBA transactions through retail commercial bank branches. Local branch underwriters might not know much about CDC debenture coordination. They often prioritize their own direct banking clients, or they just impose super strict rules. Our wholesale desk cuts out those roadblocks. We offer an institutional environment designed just for our broker partners.
1. Protected Broker Compensation Structure
We know that protecting your fees is critical for independent mortgage professionals. When you submit a commercial real estate file through our wholesale SBA 504 desk, your compensation is completely protected and clearly stated on the final settlement statement at closing. Commercial mortgage brokers can earn origination fees up to 1.00% paid directly on the senior first mortgage balance (that’s $25,000 on a $2,500,000 first note). This is all compliant with SBA fee disclosure guidelines (SBA Form 159). We make sure your broker fees are clearly included in the initial loan estimates and final closing settlement statements.
2. Streamlined Underwriting Timelines
Traditional financial institutions? They can take 60 to 90 days just to get through internal credit committee reviews for SBA transactions. We don’t do that. We operate on streamlined institutional timelines specifically designed to protect your purchase contract contingencies. Here’s how it generally works:
- Pre-Flight Assessment: We get initial term sheets and preliminary structural quotes out within 5 business days of getting a complete file.
- Formal Credit Approval: We’re simultaneously underwriting the senior first mortgage and submitting your package to our partner CDC, usually within 15 to 20 business days.
- Full Execution & Funding: Final loan closing and senior note funding happens within 30 to 45 days. This timing aligns perfectly with most commercial real estate purchase contract milestones.
3. Dedicated CDC Coordination and Dual-Track Processing
SBA 504 financing means managing two closing tracks at once: the private senior debt layer and the government-backed debenture. Our wholesale desk takes on that administrative burden of CDC coordination for you. We handle the intercreditor documentation, ordering third-party reports (like MAI appraisals, Phase I Environmental Site Assessments, and Property Condition Assessments), and meeting all SBA legal review requirements. Your contact person at our desk provides one point of communication, so you don’t have to play go-between for local CDC officers and loan processors.
Borrower and Property Eligibility Requirements
To successfully use the SBA 504 program through our wholesale desk, both the borrowing entity and the real estate must meet specific criteria. These come from federal guidelines and our own senior credit underwriting standards.
Small Business Size Standards
The SBA 504 program is meant for small to medium-sized commercial businesses. To qualify under current size standards, the primary operating business (OpCo) needs to meet these financial caps:
- Tangible Net Worth: The total tangible net worth of the consolidated operating business can’t go over $15 million.
- Average Net Income: The average net income after federal income taxes for the past two fiscal years can’t be more than $5 million.
We can also use alternative size standards based on employee counts or annual revenue. This helps ensure that capital-intensive operating companies can still access the program, even if they exceed the net worth or net income limits.
Owner-Occupancy Standards
The main goal of the SBA 504 loan program is to create jobs and help businesses grow through owner-occupied commercial properties. Passive investment real estate – like multi-tenant retail strip centers or apartment complexes purely for third-party rental income – doesn’t qualify. Here’s how owner-occupancy works:
- Existing Commercial Real Estate: The operating business needs to occupy at least 51% of the building’s total square footage. They can lease out the other 49% to third-party commercial tenants to bring in some extra rental revenue.
- Ground-Up Construction Projects: For new buildings, the operating business must occupy at least 60% of the usable square footage right after it’s finished. They should also plan to occupy up to 80% over a 10-year period. Up to 20% can be leased out short-term.
Ownership structures often use an Eligible Passive Company (EPC). Think of it as a real estate holding LLC. This company buys the property and then leases it 100% back to the Operating Company (OpCo) with a long-term lease agreement. Our wholesale desk regularly sets up these EPC/OpCo frameworks to ensure everything meets regulatory standards.
Eligible Asset Classes
We underwrite a wide range of owner-user commercial real estate assets through our wholesale SBA 504 desk. These include:
- Industrial & Logistics: Owner-occupied warehouses, light manufacturing facilities, flex industrial spaces, cold storage plants, and distribution hubs.
- Medical & Professional Office: Single-tenant or primary-occupant medical clinics, dental practices, surgical centers, veterinary hospitals, and corporate professional offices.
- Specialized & Heavy Commercial: Auto repair centers, commercial laboratories, specialized food processing spaces, and owner-operated flex space facilities.
- Hospitality & Care Facilities: Flagged hotels, assisted living facilities, and specialized care centers (though these often involve specialized capital structures).
Broker Submission Checklist and Deal Workflow
To speed up the initial deal screening and get formal term sheets from our wholesale desk, mortgage brokers should gather some key borrower documents. Sending us a complete underwriting package lets our credit team quickly assess debt service coverage and issue firm quotes.
Document Checklist for SBA 504 Senior First Mortgage Submissions
| Submission Stage | Required Financial Document | Purpose & Review Criteria |
|---|---|---|
| Step 1: Business Operations | 3 Years Business Tax Returns & YTD Financials | We use this to verify past cash flows, historical revenues, and to evaluate the trailing 12-month EBITDA. |
| Step 2: Principal Profile | Personal Financial Statement (SBA Form 413) & 3 Years Personal Tax Returns | This helps us assess the guarantor’s net worth, global liquidity, and confirm any 20%+ ownership structures. |
| Step 3: Existing Debt Profile | Schedule of Business Debt (SBA Form 2202) | We need this to detail current monthly debt service obligations, maturities, and outstanding balances. |
| Step 4: Real Estate Contract | Purchase Agreement or Detailed Construction Budget | This establishes the real estate acquisition costs, project timelines, and how hard/soft costs are allocated. |
The Dual-Track Workflow Execution
Once you submit your deal package to our wholesale desk, the process moves along a clear dual-track timeline. We do this to minimize any friction for both you and your commercial client:
- Initial Pre-Flight & Term Sheet (Days 1–5): Our underwriting team reviews the financial package. They verify owner-occupancy percentages and calculate the global Debt Service Coverage Ratio (DSCR), aiming for at least a 1.25x coverage metric on combined debt service. If everything looks good, we issue a firm conditional term sheet. It outlines senior mortgage pricing, loan term, and your estimated broker origination fees.
- Application & CDC Submission (Days 6–15): After the term sheet is signed, we put together the underwriting file for the regional Certified Development Company. This starts the concurrent processing of SBA Form 1244. We also order appraisal reports and environmental site evaluations at the same time, so we avoid sequential delays.
- Underwriting & Credit Approval (Days 16–30): Our credit committee issues formal, binding approval for the 50% first mortgage. Meanwhile, the CDC processes the 40% second-lien debenture through the SBA screening channel to get the federal authorization document.
- Closing & Loan Settlement (Days 31–45): Our closing team prepares all the final senior loan paperwork, reviews title policy commitments, and coordinates with the closing escrow agent. The 50% senior mortgage note is funded directly at closing, along with the borrower’s equity. This lets the client take ownership of the real estate, while the CDC pre-funds or bridges that secondary debenture layer.
“By structuring the senior loan through a wholesale desk designed specifically for mortgage intermediaries, brokers can avoid the usual commercial retail red tape. And you still keep full ownership of your client relationship.”
Frequently Asked Questions
How does a wholesale SBA 504 lending desk work for mortgage brokers?
A wholesale SBA 504 lending desk acts as the main institutional capital source for the 50% first mortgage part of the deal. Mortgage brokers send us borrower files. We handle the underwriting, pricing, and funding of that senior note. We also coordinate with the Certified Development Company, which manages the 40% SBA debenture.
What is the standard loan structure for an SBA 504 commercial mortgage?
The standard structure is a 50/40/10 breakdown. That means a 50% first mortgage, funded by a commercial lender or wholesale desk; a 40% second mortgage, backed by an SBA-guaranteed debenture through a CDC; and at least a 10% equity down payment from the borrower.
Can mortgage brokers earn fees on SBA 504 first mortgages?
Absolutely, yes. Mortgage brokers can earn origination fees or commissions on the 50% first mortgage that gets processed through a wholesale lending desk. These fees just need to follow federal SBA regulations and the program’s disclosure standards on SBA Form 159.
What are the eligibility requirements for SBA 504 commercial real estate financing?
To qualify, the operating business needs to be owner-occupied (that’s a minimum of 51% for existing buildings, 60% for new construction). It also needs a tangible net worth of $15 million or less, and an average net income after taxes of under $5 million for the past two years.
How does DSCR underwriting work on an SBA 504 transaction?
Debt Service Coverage Ratio (DSCR) underwriting looks at the operating business’s past and projected cash flows compared to what the total debt service would be. Our underwriters combine the annual principal and interest payments from both the 50% senior first mortgage and the estimated 40% CDC debenture payment. Our wholesale desk typically looks for a combined benchmark DSCR of 1.25x or higher. We base this on historical EBITDA or supported projection models for growing firms.
What are the primary differences between an SBA 7(a) loan and an SBA 504 loan?
Both programs help small businesses grow, but they’re for different things. The SBA 7(a) loan program is mostly a general-purpose loan. It’s for working capital, buying businesses, inventory financing, and smaller commercial real estate purchases, with a total loan cap of $5 million. The SBA 504 program, on the other hand, is specifically for big, long-term fixed assets. Think commercial real estate acquisitions and heavy equipment investments. The SBA 504 structure has no maximum total project cost cap (though the SBA debenture itself is capped at $5 million to $5.5 million, depending on if the business is a manufacturer). It also offers up to 25-year fully fixed interest rates on the debenture and generally has lower overall fees for real estate acquisitions.
