SBA 504 Loan Guide: Finance Real Estate & Equipment at Low Rates

Updated December 2025 | 6 min read

← Back to Blog

The SBA 504 loan program is specifically designed to help small businesses purchase major fixed assets like commercial real estate and heavy equipment. With below-market interest rates and long repayment terms, it's one of the most affordable ways to finance your business's growth.

Unlike the more flexible SBA 7(a) loan, the 504 program focuses exclusively on fixed assets that promote job creation and economic development. If you're planning to buy a building, construct a new facility, or invest in substantial equipment, this program could save you tens of thousands in interest costs.

How the SBA 504 Loan Structure Works

The 504 loan has a unique three-party structure that keeps rates low:

Funding Source Percentage Purpose
Bank or Credit Union 50% First mortgage position
CDC (SBA-backed) 40% Second mortgage, fixed rate
Borrower Down Payment 10% Equity contribution

The Certified Development Company (CDC) portion is funded through SBA-guaranteed debentures, which is why the interest rate on that portion is typically below market rates and fixed for the entire loan term.

Key Advantage: The CDC portion of your loan has a fixed rate for 10, 20, or 25 years, protecting you from rising interest rates over the life of your loan.

Ineligible Uses

Owner Occupancy Rule: For real estate purchases, your business must occupy at least 51% of an existing building or 60% of a new construction project.

Current SBA 504 Loan Rates and Terms

Interest rates on the CDC portion are set monthly based on current market rates for 5-year and 10-year U.S. Treasury issues. As of late 2025, effective rates typically range from 5.5% to 7% for the CDC portion.

Qualification Requirements

To qualify for an SBA 504 loan, your business must meet these criteria:

Down Payment Requirements

The standard down payment is 10%, but increases to 15% for startups (businesses less than 2 years old) or single-purpose buildings like car washes, hotels, or gas stations. New businesses purchasing single-purpose properties may need 20% down.

Advantages Over Conventional Loans

  1. Lower down payment: 10% vs. 20-30% for conventional commercial mortgages
  2. Fixed rates: Lock in your rate for up to 25 years
  3. Longer terms: Spread payments over 20-25 years instead of 5-10
  4. No balloon payments: Fully amortizing loans with predictable payments
  5. 100% financing: Can include soft costs like appraisals and environmental studies

The Application Process

Applying for an SBA 504 loan involves working with both a lender (bank or credit union) and a CDC. Here's the typical timeline:

  1. Week 1-2: Submit application and documentation to lender and CDC
  2. Week 3-4: Lender and CDC review and underwriting
  3. Week 5-6: SBA authorization
  4. Week 7-10: Closing and funding

Working with an experienced SBA lender can significantly speed up this process. Many preferred lenders have delegated authority to approve loans without waiting for SBA review.

The SBA 504 program represents one of the best financing options available for small businesses making major capital investments. With fixed rates, long terms, and low down payments, it's worth exploring if you're planning to purchase real estate or substantial equipment for your business.
