The property and use case come first
Commercial underwriting begins with the asset: property type, occupancy, condition, location, income and intended use. Owner-occupied business property, multifamily, retail, office and industrial assets can follow different credit and valuation frameworks.
Cash flow has to support the debt
Lenders often compare net operating income with proposed debt service through a debt-service-coverage ratio. The calculation may depend on current leases, historical operations, vacancy, management expenses and lender adjustments.
Sponsor strength still matters
Even when the property supports the loan, lenders may evaluate guarantor credit, experience, global cash flow, liquidity and post-closing reserves. A clear ownership and entity structure helps make the request easier to evaluate.
- Current rent roll and leases
- Historical operating statements
- Borrower and guarantor financial statements
- Entity documents
- Purchase contract or payoff information
- Business plan and exit strategy
Terms should match the exit
Loan term, amortization, recourse, prepayment provisions and rate structure should be compared against the expected hold, refinance or sale. A low initial rate can be less valuable if the structure conflicts with the investment plan.
Calculate and stress the debt-service coverage
A basic DSCR divides eligible net operating income by annual debt service. If a property produces $150,000 of lender-accepted NOI and annual debt service is $120,000, the illustrative ratio is 1.25. A lender may adjust income or expenses and may require a different threshold. The analysis should also test vacancy, repairs, lease rollover and higher future debt cost.
- Base-case NOI
- Lender-adjusted NOI
- Annual debt service
- Vacancy and expense stress
- Resulting DSCR
