2주택 공급 주택재건축사업에 따른 토지등소유자의 효용변화 연구

Abstract

The purpose of this study is to grasp the effects of two-houses purchase allowance policy in housing reconstruction operations in the economic view of the property owners. It attempted to implicate the policy through the comparison of existing residential reconstruction ways. For this, the case study areas were selected in which two-houses purchase allowance reconstructions were possible and a cost-benefit analysis through each scenario was conducted. Additionally a sensibility analysis was performed to measure changes in business fluctuation. Data was gathered from reconstruction statistics in Seoul, the National Tax Service, housing rental and sales prices of finished reconstruction projects around the site, and real estate information provided by private businesses utilizing the data from the feasibility analysis of ongoing reconstruction projects. Results showed that first, two-houses purchase allowance housing reconstruction are not beneficial to all. Property owners with 120㎡ or more land get an increase in land equity, but property owners with less than 120㎡ see a decrease in land equity. Second, sites where the proportion of land owners having more than 120㎡ was larger than those having less, show a greater increase in equity compared to sites where land owners having less than 120㎡ is more than those having 120㎡. This makes the land owner having more than 120㎡ exclusive dwelling area more profitable in the sites where the proportion of largo-size apartments is high. Two-houses purchase allowance in housing reconstructions is currently in legislation. However, it needs to grasp the utility for property owners. Owners who participated in this real estate business without implementation examples will need to compare and analyze the data to find meaning in any political implication.
