| Summary: | 碩士 === 國立臺北大學 === 不動產與城鄉環境學系 === 98 === The purpose of this paper is to examine one important foundation of sales comparison approach, that is, utility ratio among building floors. Hedonic price methods are applied to establish a model for high-rise buildings. Based on the results of the models, we address two questions. First, is there any significant price difference for the same floor of a high-rise and a low-rise building, respectively? For instance, will the households be paying a price for a unit on 5th floor of a 7-storey building different from a unit also on the 5th floor but of a 12-storey building? Second, will the price difference among floors change with the increase of building age? In addition, we attempt to establish a table of utility ratio among floors for buildings of various age cohorts. Finally, we use the table to examine the effects of building age on utility ratio among floors and based on which we then provide further policy suggestions.
Summarize the research findings. First,the price for the same floor of a low-rise building is higher than a high-rise building. In other words, a price for a unit on 5th floor of a 7-storey building is more expensive than a unit also on the 5th floor but of a 12-storey building. Second, Practical work should establish a table of utility ratio among floors for buildings of various storeys, and although the effect of the building age upon utility ratio among floors is not as obvious as the storey, but it still needs to establish a table of utility ratio among floors for the pre-owned house and the new-owned house, respectively, or the evaluated value would be biased. In the end, the price difference among floors diminish with the increase of building age, it is because that improvements will depreciate with increase of the building age, so the improvements percentage of the housing price will diminish.
