역세권 공공임대주택의 현금분담금등 사업성 분석모형

[Purpose]This study extends the model of Kim and Kwon(2022, 2023) and develops the extended model of shared cash payments to help analyse the feasibility of the public rental housing projects in the station’s sphere of influence area. [Methodology]The deterministic static model of shared cash payments is extended to the occasion of the public rental housing, considering upzoning of land use and thereby increased building volume ratio or floor area ratio(FAR). The model is extended to reflect the cash payments effect of the price and volume of public rental offering. [Findings]When there are some public offering like the public rental housing or the land donation in compensation for upzoning of land use and increased FAR, the shared cash payments of owners of the old apartments needs to incorporate, beyond existing 5 elements, the additional elements, such as the difference between the prices of general sale and public rental offering, and the ratio of public rental offering versus existing owners’ portion of new apartments. [Implications]This study can help perform the early, frequent, timely feasibility analysis of the public rental housing projects in the region around the train stations, enabling the owners of apartments to make rational choice of reconstruction course.
