A commercial mortgage is a debt instrument secured by a lien on a commercial property, such as an office building, shopping center, industrial warehouse, or apartment complex. Unlike residential mortgages, which are based on a borrower's personal credit and income, commercial loans are primarily evaluated based on the income-generating potential of the property itself. These loans are essential for business owners looking to purchase their own operating space or investors seeking to build a portfolio of income-producing real estate.
Commercial financing is not "one size fits all." Options range from SBA 7(a) and 504 loans for owner-occupied businesses to CMBS (Conduit) loans for large-scale investors. Each program has distinct requirements for down payments, interest rate structures, and recourse versus non-recourse terms.
The most critical metric in commercial underwriting is the DSCR. This is calculated by dividing the property’s Net Operating Income (NOI) by its annual debt service. Most lenders look for a ratio of 1.25 or higher, ensuring the property generates enough cash flow to cover the mortgage and operating expenses comfortably.
Commercial loans typically require larger down payments than residential loans. While some SBA programs allow for 10% down, most conventional commercial lenders require an LTV of 65% to 75%, meaning the borrower must provide 25% to 35% of the purchase price as equity.
It is common for a commercial loan to have a 25-year amortization schedule but a much shorter term, such as 5 or 10 years. This results in a "balloon payment" at the end of the term, at which point the borrower typically refinances the remaining balance or sells the asset.
Lenders distinguish between a business owner buying a building for their own operations (Owner-Occupied) and an investor buying a building to lease to third parties (Investment). Owner-occupied loans often feature more favorable terms and lower down payments through government-backed programs like the SBA.
Many commercial loans include "lock-out" periods or prepayment penalties like Yield Maintenance or Defeasance. These clauses protect the lender's expected yield if the borrower decides to pay off the loan early, making it important to align the loan term with your long-term hold strategy.
Commercial due diligence is more rigorous than residential. Lenders will require a Phase I Environmental Site Assessment (ESA) to ensure there is no soil or groundwater contamination, along with a specialized commercial appraisal that focuses on the income-capitalization approach to value.
In a recourse loan, the lender can pursue the borrower’s personal assets if the property defaults. In non-recourse financing—common in large-scale commercial deals—the lender’s only "recourse" is to seize the property itself, though "bad boy carves-outs" still hold individuals liable for fraud or negligence.
