What is a Commercial Mortgage? Understanding Business Property Financing

A commercial mortgage (also known as a commercial real estate loan, business property loan, or CRE financing) is a mortgage loan secured by commercial property rather than residential real estate. These specialized loans are used to purchase, refinance, or develop income-producing properties such as office buildings, retail centers, apartment complexes, industrial facilities, hotels, and mixed-use developments.

Unlike traditional residential mortgages where qualification is primarily based on the borrower's personal income and credit history, commercial mortgage lenders focus heavily on the property's ability to generate income and produce positive cash flow. The Debt Service Coverage Ratio (DSCR) and Loan-to-Value (LTV) ratio are critical metrics in the underwriting process.

Commercial real estate financing typically requires larger down payments (20-30% minimum), has shorter loan terms (5-25 years), carries higher interest rates than residential mortgages, and involves more complex underwriting. These loans are used by businesses and investors to acquire income-producing assets, with financing structured around property performance and equity.

Types of Commercial Mortgage Loans and CRE Financing Options

1. Permanent Commercial Mortgages (Traditional Financing)

Long-term financing for stabilized, income-producing properties with established cash flow. These loans typically offer 10-25 year terms with fixed or variable interest rates and are commonly used for owner-occupied commercial properties or investment real estate with proven performance.

2. SBA 504 Loans (Small Business Administration)

Government-backed commercial real estate loans with as little as 10% down payment, fixed interest rates, and 20-25 year amortization periods. Available to small businesses purchasing owner-occupied commercial properties, with maximum loan amounts up to $5.5 million.

3. Bridge Loans (Short-Term Commercial Financing)

Short-term financing (12-36 months) used to "bridge" the gap between immediate funding needs and long-term financing. Common for property acquisitions, renovations, lease-up periods, or refinancing. Higher interest rates but faster approval and flexible terms.

4. Commercial Construction Loans

Financing for ground-up construction or major renovation of commercial properties. These loans disburse funds in draws as construction progresses, typically converting to permanent financing upon completion. Requires detailed construction plans, budgets, and experienced developers.

5. CMBS Loans (Commercial Mortgage-Backed Securities)

Commercial mortgages pooled together and sold as securities to investors. These loans offer competitive rates for larger properties ($2M+), are typically non-recourse, but have strict servicing requirements and potential prepayment penalties.

6. Hard Money Loans (Private Commercial Lending)

Asset-based loans from private lenders focusing on property value rather than borrower credit. Fast approval (days to weeks), higher interest rates (9-15%+), shorter terms (6-24 months), used for fix-and-flip projects, distressed properties, or borrowers who don't qualify for traditional financing.

How to Qualify for a Commercial Mortgage: Requirements and Documentation

Borrower Requirements

  • Credit Score: Minimum 660-680 (700+ commonly associated with lower interest rates). Commercial lenders review both personal and business credit history.
  • Net Worth: Many lenders require net worth equal to or exceeding the loan amount, demonstrating financial stability.
  • Liquidity: Sufficient cash reserves to cover 6-12 months of debt service payments plus closing costs and working capital.
  • Experience: Demonstrated experience in commercial real estate ownership, property management, or relevant business operations.
  • Down Payment: 20-30% of property value in cash or equivalent equity (SBA loans may allow 10% down).

Property Requirements

  • DSCR: Minimum 1.20-1.25 (property generates 20-25% more income than debt service). Higher ratios are associated with lower perceived lender risk.
  • LTV Ratio: Maximum 75-80% (varies by property type and lender). Lower LTV ratios are associated with lower lender risk.
  • Occupancy: Stable tenant base with lease agreements in place. Many lenders require minimum 80-90% occupancy for multi-tenant properties.
