Extracting Land Value
Land value is determined by subtracting the depreciated value of improvements (buildings, structures) from the total property value.
Formula
Depreciated Improvement = Replacement Cost x (1 - Age / Useful Life)
Land Value = Total Property Value - Depreciated Improvement
Why Land Value Matters
计算示例
A $500,000 property has improvements that would cost $350,000 to replace and are 15 years old with a 50-year useful life.
- Depreciation percentage: 15 / 50 = 30%
- Depreciated improvement value: $350,000 x (1 - 0.30) = $245,000
- Land value: $500,000 - $245,000 = $255,000
- Land-to-value ratio: $255,000 / $500,000 = 51.0%
