Property Valuation

The principle of 'contribution' in real estate appraisal states that:

AA property's value is determined by the sum of all its improvements
BThe value of a component is measured by its contribution to the total value of the property✓ Correct
CAll properties contribute to their neighborhood's overall value
DProperty values are contributed to by market conditions outside the property

Explanation

The principle of contribution states that the value of any component of a property is measured by how much it adds to the total value of the property, not by its cost. A swimming pool costing $50,000 may only add $20,000 in market value.
