Final answer:
An absent feature in the subject property compared to a comparable property usually leads to an underestimation of its value, as the subject property lacks an attribute that adds value. The correct option is c.
Step-by-step explanation:
When comparing properties in real estate for valuation purposes, any feature found in a comparable property that is not present in the subject property typically results in an underestimation of value.
This is because the subject property lacks an attribute that is considered valuable in the market, as evidenced by the comparable property that includes it.
In real estate valuation, adjustments must always be made for differences between properties to establish a fair market value.
If a feature increases the value of a property, its absence in another would naturally decrease the value of that property in comparison. The correct option is c.
