An owner installs an antique fireplace in their living room. The cost is $20,000, but it only adds $7,000 in appraised value to the property overall. The homeowner is frustrated as they expected the added value to be at least equal to installation costs. Which economic principle is demonstrated here?

This principle refers to how property values can fluctuate over time due to various factors such as market trends or neighborhood developments. It does not directly relate to the immediate appraisal value versus installation cost scenario presented in the question.

The principle of substitution posits that a property's value is determined by the cost of acquiring a similar substitute property. It suggests that buyers will not pay more for a property than it would cost to purchase an equivalent one. This principle does not apply to the discrepancy between installation costs and appraised value in the context of the fireplace.

This principle relates to the expectation of future benefits or value from a property, influencing its current value. In this situation, the homeowner's expectation of added value does not align with the actual appraised increase, making anticipation irrelevant to the principle highlighted in the question.
