THE SHORT ANSWER
Commercial real estate valuation estimates what a property is worth using evidence about income, comparable transactions, and physical assets. Direct capitalization and discounted cash flow are common income approaches. A useful valuation explains its assumptions, date, and evidence; it is not simply the asking price entered into a calculator.
Begin with the question and valuation date
Clarify whether you are evaluating current as-is value, value after planned work, or an assumed future sale. Those are different questions. A stabilized figure can depend on additional money, time, and leasing that have not yet occurred.
Identify the property's rights and limitations, including leases, permitted use, physical condition, and access. A comparable building with different lease obligations or redevelopment rights may not be a close economic comparison.
Use direct capitalization for a stated income stream
Direct-capitalization value = stabilized annual NOI ÷ selected cap rate. Both inputs require support. Review what the NOI includes and how the cap-rate assumption relates to comparable assets and current evidence.
With hypothetical NOI of $180,000, a 6% assumption gives $3,000,000. At 7%, it gives approximately $2,571,429. These are illustrative calculations, not current market rates or an appraisal.
| Illustrative NOI | Illustrative cap rate | Calculated value |
|---|---|---|
| $180,000 | 6.0% | $3,000,000 |
| $180,000 | 6.5% | $2,769,231 |
| $180,000 | 7.0% | $2,571,429 |
Use a cash-flow model when timing matters
A discounted cash flow analysis lays out future income and costs, then discounts modeled cash flows and net terminal value to the valuation date. It can make lease-up, rent steps, vacancy periods, and major spending more visible than one capitalization ratio.
The exit cap rate, sale date, selling costs, and discount rate all affect the result. Show sensitivity to these assumptions. A detailed spreadsheet can still produce an unreliable value if unsupported growth assumptions drive it.
Cross-check with transactions and physical economics
Comparable sales can provide another perspective, with adjustments for differences such as location, condition, lease terms, timing, and size. A cost approach examines land value and improvement cost with appropriate depreciation or obsolescence considerations.
Reconcile the approaches rather than averaging unrelated numbers mechanically. A professional appraiser can explain the relevance and limitations of each method for a particular assignment.
For investment planning, take the next step from property value to investor proceeds: deduct selling costs and debt payoff, and consider applicable taxes separately. A gross property valuation is not the amount an owner takes home.
Common questions
Is the purchase price the same as market value?
Not necessarily. Price is what parties agree to pay. A valuation is an estimate based on a defined purpose, date, rights, and evidence.
Does higher NOI always produce an equal increase in value?
Not automatically. The durability of income, capital needs, cap-rate evidence, and other market factors also matter.
