Two fundamental concepts underpin all real estate valuation: Market Value — the most probable price a property would sell for in an open market — and Investment Value (also called value-in-use), which reflects the worth of an asset to a specific investor with specific return requirements and financing assumptions.
| Dimension | Market Value | Investment Value |
|---|---|---|
| Definition | Price in open, competitive market | Value to a specific buyer/investor |
| Basis | Comparable transactions | Investor-specific assumptions |
| Discount Rate | Market-derived cap rate | Investor's required rate of return |
| Financing | Typically cash basis | Leveraged or specific structure |
| Used by | Valuers, lenders, tax authorities | Buyers, portfolio managers |
| Regulatory role | Used in financial reporting | Internal decision-making tool |
Highest and Best Use is the legally permissible, physically possible, financially feasible, and maximally productive use of a property. It is the foundation of most market value estimates, as a property should be valued at the use that generates the highest value, not its current use.
Income Approach
The most common approach for income-producing real estate. Value is derived from the property's ability to generate future income, either through direct capitalisation (applying a cap rate to net operating income) or discounted cash flow analysis.
Cost Approach
Estimates value as the cost to reproduce or replace the improvements, plus land value, less accumulated depreciation. Most useful for new construction, special-use properties, or where comparable sales data is scarce. Rarely used in isolation for investment decisions.
Comparable Sales Approach
Derives value by analysing recent transactions of similar properties, adjusting for differences in location, size, condition, timing, and physical attributes. Produces price per square metre or price per unit benchmarks widely used in residential and land valuation.
| Comparable | Sale Price | GFA (m²) | Price/m² | Adjustments | Adj. Value |
|---|---|---|---|---|---|
| Comp A — DIFC Tower | $22,500,000 | 3,200 | $7,031 | +5% location | $7,383 |

| Comp C — JLT Office | $14,700,000 | 2,200 | $6,682 | −3% age | $6,481 |

✦ Key Takeaways — Part 1
- Market Value reflects open-market consensus; Investment Value is investor-specific
- HBU analysis determines the most productive legal use before valuation begins
- The Income Approach dominates investment real estate; Cost Approach for development
- Comparable sales provide market evidence but require careful adjustment for differences
- Never conflate cap rate with discount rate — they serve different analytical purposes
⚠ Risk Areas — Part 1
- Using stale comparable data in a moving market leads to mispricing
- Ignoring HBU analysis can result in paying for a use that planning won't permit
- Market cap rates compress quickly in bull markets, overstating values
- Cost approach can be manipulated by inflating replacement cost estimates
- Circular valuation: using model outputs to set discount rates creates bias
