Abstract

As research methods, this study would estimate the Net Present Value (NPV), Internal Rate of Return (IRR) and Profitability Index (PI) through an analysis of the feasibility of the case of the Seoul land-leasehold social housing, a type of the community housing and analyze changes in the business value according to the changes of the main factors through a sensitivity to propose a plan for the vitalization of the land-leasehold social housing.As a result of an analysis of the business feasibility of the land-leasehold social housing (Operation for 40 years) selected as the case, the NPV was 11,892,000 won and the IRR was 3.69% and the PI was 1.044. Thus, it turned out that all the indicators in the feasibility analysis secured a business value; however, it is judged that the level is considerably lower for the independence of the private sector. Measures for the vitalization of land-leasehold social housing so that the private sector will be able to be independent in the future can be suggested as follows:First, it is necessary to adjust the land rental rates. The land rental rates taking up the most part as fixed costs affect business feasibility closely. Thus, for the expansion of private business operators’ participation in the project, the adjustment of the land rental rates is needed.Second, institutional countermeasures are needed, so that private business operators can minimize costs and make it possible to provide quality services by realizing the economy of scale in the construction and operation and management.
