A commercial mortgage is a loan secured by commercial property — office buildings, retail spaces, warehouses, or multifamily housing (5+ units). Commercial mortgages differ from residential loans with shorter terms (5-20 years), higher rates (typically 1-2% above residential), larger down payments (20-35%), and underwriting based on the property's income rather than the borrower's personal income.
Commercial real estate financing operates in a fundamentally different world than residential mortgages. The underwriting focuses on the property income rather than the borrower personal finances, the loan structures include balloon payments that force refinancing, and the requirements for down payments and documentation are significantly more demanding.
How Commercial Mortgages Differ from Residential
The most important difference is the focus of underwriting. Residential lenders primarily evaluate your personal income, credit score, and DTI ratio. Commercial lenders primarily evaluate the property income and its ability to service the debt. Your personal finances matter, but the property financials are the main event.
Commercial loans also use a different structure. Instead of a 30-year fixed rate mortgage, most commercial loans feature a 5 to 10 year balloon term with a 25-year amortization schedule. This means your monthly payment is calculated as if the loan is paid over 25 years, but the remaining balance comes due after the balloon period. At that point, you must refinance, sell, or pay off the balance. This creates refinancing risk: if rates have risen or the property value has declined, refinancing may be more expensive or difficult.
Rates on commercial mortgages run 1 to 2 percentage points above residential rates. Currently, that means 7% to 9% for most property types. SBA 504 loans for owner-occupied commercial properties can be lower at 6% to 7%. Calculate your specific scenario with our Commercial Mortgage Calculator.
The Three Numbers Lenders Care About Most
Debt Service Coverage Ratio (DSCR) is the single most important metric. It measures whether the property generates enough income to cover loan payments. The formula is simple: Net Operating Income divided by Annual Debt Service. A DSCR of 1.25x means the property generates 25% more income than needed for loan payments. Most lenders require a minimum of 1.25x, and 1.50x or higher is considered strong.
Loan-to-Value (LTV) determines how much the lender will lend relative to the property value. Commercial lenders typically cap LTV at 65% to 80% depending on property type. Multifamily properties get the most favorable terms at up to 80% LTV, while office and retail may be capped at 65% to 75%. Special purpose properties like hotels and restaurants often require 60% to 65% LTV. This means down payments of 20% to 40%.
Cap rate measures the property return independent of financing. It is calculated as NOI divided by property value. A $2.5 million property generating $200,000 in NOI has an 8% cap rate. Cap rates vary by property type and market. Analyze your investment with our Cap Rate Calculator.
Property Types and Their Lending Profiles
Multifamily (apartments) gets the best financing terms: 75-80% LTV, lowest rates, and the most lender competition. This is because apartments have diversified income streams and strong historical performance. Office has become more challenging post-pandemic with higher vacancy rates leading to stricter underwriting. Retail varies dramatically based on tenant quality and lease terms, with strong single-tenant net-leased properties getting excellent terms while multi-tenant strip centers face scrutiny. Industrial/warehouse has emerged as a lender favorite due to e-commerce driven demand, offering terms comparable to multifamily.
How to Strengthen Your Application
Three strategies improve your odds of approval and better terms. First, demonstrate strong and growing NOI with detailed rent rolls, historical occupancy data, and realistic projections. Second, bring a larger down payment as every 5% increase in down payment typically improves your rate by 0.125% to 0.25%. Third, show real estate experience as lenders heavily weigh borrower experience in commercial property management. First-time commercial buyers should consider partnering with experienced operators or starting with smaller properties to build a track record.
Preparing Your First Commercial Loan Application
First-time commercial real estate buyers face a steeper learning curve than residential buyers. The documentation requirements are more extensive, the financial analysis is more complex, and the negotiation involves more variables. Start by assembling a comprehensive package that includes the property financial history (at least 3 years of operating statements), current rent roll with lease expiration dates, property condition assessment, your personal financial statement and resume of real estate experience, and a clear business plan explaining your strategy for the property.
The operating statement is the most critical document. Lenders will scrutinize every line item: gross rental income, vacancy rate, operating expenses (taxes, insurance, maintenance, management fees, utilities), and the resulting net operating income. Present your analysis professionally using standardized formats and be prepared to explain any anomalies such as a recent vacancy spike or deferred maintenance costs that temporarily reduced NOI.
Build relationships before you need a loan. Visit local banks and credit unions that are active in commercial lending in your market. Introduce yourself, discuss your experience and goals, and ask about their lending criteria and current appetite for your property type. Commercial lending is relationship-driven far more than residential lending, and a banker who knows you and trusts your judgment will advocate for your loan through the approval committee. Many experienced investors maintain relationships with three to four commercial lenders to ensure competitive terms and backup options for every deal.

Understanding Commercial Loan Covenants
Commercial mortgages include loan covenants that residential loans do not have. These are ongoing requirements the borrower must maintain throughout the loan term. Common covenants include maintaining a minimum DSCR of 1.20 to 1.25x at all times, maintaining adequate property insurance and environmental compliance, providing annual financial statements and rent rolls to the lender, restricting additional debt on the property without lender approval, and maintaining the property in good condition. Violating a covenant can trigger a default even if you are current on payments. Before signing, understand every covenant and ensure your property financials provide a comfortable margin above the minimums. Most experienced commercial borrowers build financial models projecting covenant compliance under stress scenarios including higher vacancy rates, increased operating costs, and interest rate increases at the balloon refinance point.
| Loan Type | Rate Range (2026) | LTV Max | Term | Best For |
|---|---|---|---|---|
| Conventional (bank) | 7-9% | 65-75% | 5-25 yr | Strong borrowers, stabilized properties |
| SBA 504 | 5.5-7% | 90% | 10-25 yr | Owner-occupied commercial |
| SBA 7(a) | 10-13% | 85% | 10-25 yr | Mixed-use, working capital + real estate |
| CMBS (securitized) | 6.5-8.5% | 75% | 5-10 yr | Larger properties ($2M+) |
| Bridge loan | 9-14% | 70-80% | 6mo-3yr | Value-add, renovation, quick close |
Commercial Loan Rates and Terms in 2026
Commercial mortgage rates operate differently from residential rates because they are not standardized through Fannie Mae or Freddie Mac. Instead, commercial lenders set rates based on the property's income potential, the borrower's financial strength, and current capital market conditions. In 2026, typical commercial mortgage rates range from 6.5% to 9.5%, depending on property type, loan-to-value ratio, and borrower creditworthiness — significantly higher than residential rates.
Loan terms also differ dramatically. Most commercial mortgages have 5, 7, or 10-year terms with 25-30 year amortization schedules, creating a balloon payment at maturity. This means your monthly payment is calculated as if you are paying over 25-30 years, but the remaining balance is due in full at the end of the term. You will either need to refinance, sell the property, or pay the balloon. This structure creates refinancing risk: if rates have risen or property values have declined at maturity, refinancing may be difficult or expensive.
SBA 7(a) loans offer the most favorable terms for small commercial purchases: up to $5 million, 10-25 year terms with no balloon, and rates of prime + 2.25-2.75% (approximately 8.75-9.25% in 2026). SBA 504 loans provide even longer terms (20-25 years) at fixed rates for owner-occupied commercial properties, with the added benefit that the SBA portion (40% of the project) carries a below-market fixed rate. The trade-off: SBA loans require extensive documentation, 10-20% down payment, and processing times of 60-90 days.
How to Evaluate a Commercial Property Before Buying
Commercial real estate valuation centers on income, not comparables. While residential properties are valued primarily by comparing recent sales of similar homes, commercial properties are valued by their income-generating potential. The three key metrics every commercial buyer must understand:
Net Operating Income (NOI) is the property's annual rental income minus all operating expenses (property management, maintenance, insurance, property taxes, utilities if landlord-paid, reserves). NOI does not include mortgage payments or income taxes. A property generating $200,000 in gross rent with $80,000 in operating expenses has an NOI of $120,000. This is the foundation for all commercial property valuation.
Cap Rate (capitalization rate) is NOI divided by the purchase price. A $1.2 million property with $120,000 NOI has a cap rate of 10%. Higher cap rates indicate higher returns but also higher risk — a 4% cap rate suggests a stable, low-risk property (Class A office in a prime location), while a 10% cap rate suggests higher risk (older property, secondary market, or less stable tenant mix). In 2026, average cap rates range from 5-7% for institutional-quality properties to 8-12% for value-add or secondary market investments.
Debt Service Coverage Ratio (DSCR) is NOI divided by annual debt payments (principal + interest). Lenders require a minimum DSCR of 1.20-1.35, meaning the property must generate 20-35% more income than needed to service the debt. A property with $120,000 NOI and $92,000 in annual mortgage payments has a DSCR of 1.30 — meeting most lenders' requirements. If your DSCR falls below the minimum, you will need a larger down payment to reduce the loan amount until the ratio qualifies.
The Five Most Common Commercial Loan Types
Conventional bank loans offer the lowest rates (6.5-8%) but require 20-30% down, excellent credit (700+), and strong DSCR (1.25+). Best for experienced investors with proven track records and strong financials. Terms of 5-10 years with 25-year amortization. Processing time: 30-60 days.
SBA 7(a) loans up to $5 million with 10-25 year terms. Ideal for owner-occupied properties where your business operates from the building. Down payments of 10-20%. Rates of prime + 2.25-2.75%. The SBA guarantees 75-85% of the loan, making lenders more willing to approve borderline applicants. Processing: 60-90 days.
SBA 504 loans combine a first mortgage (50% from a bank), a second mortgage (40% from a Certified Development Company at a fixed below-market rate), and 10% borrower down payment. Best for purchasing fixed assets like commercial buildings or heavy equipment. The CDC portion carries a 20-25 year fixed rate, typically 0.5-1.0% below conventional rates. Minimum project size: $125,000.
CMBS (Commercial Mortgage-Backed Securities) loans are pooled and sold to investors, resulting in competitive rates but inflexible terms. Prepayment penalties are severe (defeasance or yield maintenance). Best for stabilized properties with predictable income that the borrower plans to hold for the full loan term. Minimum loan: typically $2-5 million.
Hard money and bridge loans provide fast funding (7-14 days) for time-sensitive acquisitions or properties that do not qualify for conventional financing. Rates of 10-15% with 1-3 year terms and 1-4 points in origination fees. Use only as short-term financing while you stabilize a property's income (through renovations or lease-up) enough to refinance into a conventional loan.
What Your Result Means
DSCR above 1.30: Strong qualification — lenders see comfortable coverage. You will access the best rates and terms.
DSCR 1.15-1.30: Acceptable but tight. Lenders may require additional reserves, higher down payment, or personal guarantees.
DSCR below 1.15: The property's income barely covers the debt service. Most lenders decline below 1.20. Consider: a larger down payment (reducing the loan and improving DSCR), a different property with higher NOI, or improving the property's income before applying.
