Property Valuation

AHow much the addition cost to build
BHow much the addition contributes to the overall market value of the property✓ Correct
CHow much the owner contributed to the mortgage
DThe percentage of the addition's value in the total property

Explanation

The principle of contribution holds that the value of any component equals its contribution to the total property value, which may be more or less than the component's actual cost. A $50,000 pool addition may only contribute $20,000 to market value.
