Key perspective

Commercial mortgage underwriting evaluates both the borrower and the property as an income-producing or business-use asset. The quality of leases, net operating income, location, property condition and sponsor strength can be as important as the requested LTV.

Property and use

Commercial financing differs across mixed-use, retail, office, industrial, multi-unit, automotive, hospitality, land and specialized properties. Lender appetite can vary substantially by property type and location.

NOI and DSCR

Net operating income reflects property income after eligible operating expenses but before financing costs. Debt-service coverage compares that income with required mortgage payments. Lenders may normalize revenue, vacancy and expenses rather than accept the borrower’s calculation unchanged.

Borrower and guarantor strength

Lenders may review net worth, liquidity, experience, credit, corporate structure, business financial statements and guarantees. Owner-occupied properties may also be assessed through the operating company’s cash flow.

Third-party reports and closing

Commercial files may require appraisal, environmental review, building condition information, leases, rent roll, corporate documents and legal due diligence. The closing timeline should account for these reports.
