Final answer:
The student's question involves the appraisal of a ranch home using comparable newly constructed houses in the area to calculate the property value through the cost approach. Housing prices have historically shown a steady increase, both on a national scale and with local variations.
Step-by-step explanation:
The question relates to a real estate appraisal using the cost approach method. This entails analyzing similar properties recently constructed in the neighborhood to determine both the value of the land and the cost of construction for the subject property. Data is given from three different builders, each selling houses of varying sizes and features. It is necessary to adjust for differences such as square footage and the presence or absence of a carport.
Housing prices trends show a steady increase over time. For instance, the median sales price for a new one-family home in 1990 was $122,900, which grew to $294,000 by 2015, as per U.S. Census data. This reflects a national average financial return of 3.1% per year in the housing market, although local market conditions can vary significantly.
