When estimating the value of a fireplace in a single-family home, the most important principle is the principle of ______.

• A. substitution
• B. contribution
• C. conformity
• D. anticipation

Answer: (B)

The key idea is that value comes from what a feature adds to the whole property. The contribution principle says the value of a fireplace is determined by how much it boosts the home's overall price, not by what it cost to install or by any standalone value. So in estimating the fireplace’s value, you look at how buyers’ willingness to pay for a home with a fireplace compares to similar homes without one. This explains why the fireplace might add more value in some markets and less in others, independent of installation cost. Substitution would center on comparing to a similar home to establish price, which is useful for overall market value but not as directly about how much the fireplace itself adds. Conformity concerns whether the home fits neighborhood norms, and anticipation deals with expected future benefits, which are less about the feature’s immediate contribution to value.
