SBA 504 Loans: The Refinancing Gold Mine

Refinance commercial real estate with SBA 504 loans for lower rates and longer terms. Save thousands monthly while building equity in your property.

Business owners are bleeding cash through commercial real estate loans with crushing rates and balloon payments. Meanwhile, SBA 504 loans offer fixed rates below 6% for 25 years – yet 95% of eligible property owners have never explored this refinancing goldmine. The difference? About $3,000 per month in savings on a typical commercial property.

This guide reveals how to slash your commercial mortgage payments by 40%, extend terms to 25 years, and convert adjustable rates to fixed – all while keeping more equity in your business. You’ll discover exactly when SBA 504 loans make sense for refinancing and how to structure deals that lenders rush to approve.

Understanding the SBA 504 Refinancing Advantage

The SBA 504 program structures refinancing uniquely: 50% comes from a bank loan, 40% from an SBA debenture, and you contribute just 10% equity. The SBA portion locks in rates for 20-25 years, protecting you from market volatility while traditional commercial loans reset every 5 years.

Here’s what makes this powerful: the SBA debenture carries below-market rates because it’s backed by government guarantees. Combined with competitive bank financing for the first mortgage, your blended rate beats anything available in the private market.

Qualifying Properties and Eligibility Requirements

Your commercial property qualifies for SBA 504 loans if your business occupies at least 51% of the space. This includes office buildings, warehouses, manufacturing facilities, retail spaces, and even special-purpose properties like hotels or car washes. Multi-tenant buildings work if you occupy the majority.

The 85% Rule That Changes Everything

Traditional refinancing limits you to 75% loan-to-value. The SBA 504 program allows up to 85% LTV for owner-occupied properties. This extra 10% means you extract more equity for working capital or expansion while still lowering payments. On a $2 million property, that’s an additional $200,000 in your pocket.

Loan Feature Traditional Commercial SBA 504 Refinance Your Advantage
Maximum LTV 75% 85% 10% more cash out
Rate Structure Variable/5-year reset Fixed 20-25 years Rate certainty
Term Length 10-15 years 20-25 years Lower payments
Prepayment Penalty Typically 3-5% Declining scale More flexibility

The Two-Loan Structure Explained

SBA 504 loans split financing between two sources, creating unique advantages. The first mortgage (50% of project cost) comes from a bank at market rates, typically with a 10-year term. The second mortgage (40%) comes through a Certified Development Company (CDC) as an SBA debenture with fixed rates for 20-25 years.

This structure protects you twice: the bank loan is smaller, so you qualify easier, and the SBA portion locks in low rates for decades. Even better, you can often negotiate the bank portion as interest-only initially, maximizing cash flow during transition periods.

Cash-Out Refinancing for Growth

The SBA allows cash-out refinancing when proceeds fund business expansion. This means you can tap equity for equipment purchases, hiring, marketing, or opening new locations. Unlike traditional refinancing that restricts cash use, SBA financing supports your growth plans.

Document your expansion plans clearly in your SBA loan application. Show how extracted equity will generate returns exceeding borrowing costs. Include projections, quotes for equipment, or lease agreements for new locations. This transforms your refinance from debt restructuring into growth financing.

Timing Your Refinance Perfectly

Refinance when your current loan has less than 15 years remaining or faces a rate reset within 24 months. The best timing aligns with SBA debenture sales, which occur monthly with rates announced in advance. This transparency lets you lock rates at optimal moments.


  • Balloon payment approaching: Refinance 6-12 months before maturity

  • Rate adjustment coming: Start process 90 days before reset

  • Property appreciation: Refinance after significant value increases

  • Business expansion: Time with growth capital needs

The Application Process Simplified

Start by selecting both a preferred lender and a Certified Development Company (CDC). The CDC packages your SBA portion while the lender handles the conventional mortgage. This dual-partner approach requires coordination but delivers superior results.

Required Documentation


  • Three years of business tax returns and financial statements

  • Current rent roll (if multi-tenant property)

  • Environmental assessment (Phase I typically required)

  • Property appraisal (ordered after preliminary approval)

  • Business plan or expansion projections

Real Numbers: Your Refinancing Savings

Consider a typical $1.5 million commercial property with a $1.2 million loan at 8% adjustable rate, 15 years remaining. Monthly payment: $11,469. After SBA 504 refinancing at a 5.5% blended rate over 25 years, new payment: $7,385. Monthly savings: $4,084. Annual savings: $49,008.

Beyond payment reduction, you’ve eliminated rate risk for 25 years and freed up nearly $50,000 annually for growth. That funds two new employees, major equipment purchases, or significant marketing expansion – all from restructuring existing debt.

Common Refinancing Mistakes to Avoid

The biggest mistake? Waiting too long. Many owners refinance only when forced by balloon payments, missing years of savings. Others fail to account for closing costs (typically 2-3% of loan amount) in their calculations. Factor these into your analysis but remember they’re often recouped within 6-8 months through payment savings.

Avoid choosing lenders based solely on rate quotes. SBA 504 loans involve complex structuring where experience matters more than marginal rate differences. Work with lenders and CDCs that have strong track records and can navigate the unique requirements efficiently.
