The direct answer
Commercial real estate includes income-producing property such as office, retail, industrial, multifamily and specialized assets. Underwriting usually starts with income, operating expenses, NOI, lease structure, financing and valuation metrics rather than relying on one headline return.
Understand the property type and lease model
Different property types have different expense responsibilities, tenant risks, lease terms and capital requirements. A metric that is informative for one asset may need different assumptions for another.

Build from property income to NOI
Start with contractual and market rent, vacancy and other income, then subtract operating expenses that belong above NOI. Debt service, income taxes and many capital items are analyzed separately.
Use multiple core metrics
Cap rate, DSCR, debt yield, LTV, cash flow and return measures each capture a different part of the deal. Review them together with lease rollover, capital needs and market evidence.
Worked example
A $10 million property with $650,000 of stabilized NOI has a 6.5% cap rate. That alone does not show whether the financing is safe or whether major tenant rollover could disrupt future cash flow.

Common mistakes and limitations
Do not compare commercial properties using cap rate alone without checking the NOI definition, lease structure and capital needs.
Does not calculate commercial loan terms, taxes or future sale value unless supplied in an optional scenario mode.
Frequently asked questions
What is the main income metric in commercial real estate?
NOI is a common property-level measure, but the exact underwriting also depends on leases, expenses and asset type.
Is commercial real estate valued only by income?
No. Income, comparable sales, cost and other evidence can all be relevant depending on the asset and assignment.
