A judgment on the redevelopment projects' predicted profitability is an essential decision-making element for the success of the redevelopment projects. It is necessary to review the literature on profitability of redevelopment project and draw risk factors that could affect profitability through the risk analysis based on surveys. It is also necessary to judge profitability prediction toward the business value of the redevelopment project in the planning phase according to the risk analysis results which can affect the profitability prediction. In order to prevent the growing difficulties in executing the projects, a profitability prediction model is proposed using the method of management and disposal based on a proportional calculation that can estimate the share of expenses in order to judge profitability in the planning phase. With the improvement of profitability prediction models, it is possible to appropriately judge profitability in the planning phase in order to allow the prevention of suspension, reduction of project term, reduction of cost, and making of rational decisions.

1990s, Construction market continued to grow in South Korea exceeding 20% of GDP. In 2015, more than 30 years of old multi-family dwellings amounted to 4.93 million and it continues to increase until 2019. In Particular, the share of Public rental Housing accounts for 90.6% of South Korea's Total aging housing. Before checking the feasibility of Construction Project Management such as Renovation and Reconstruction, Checklists were presented through price impact factor analysis and analysis of housing construction system(Regulation). Based on 32 Price Influencing factors and 20 Indicators based on the housing construction system The Construction project management seems appropriate. As a result, the 22 complexes were found to be suitable for remodeling. This study is meaningful enough to be used for Domestic rental Housing construction and Construction project management and to suggest specificity. Future Research is needed to Quantify the checklist.

This study aims to evaluate the feasibility of remodeling business by predicting the future price of apartment house after remodeling using Hedonic Price Model. The data concerning such 9 independent variables as location, unit size, unit plan, landscape, parking, the number of elapsed years after completion, number of units, mechanical performance, interior from 25 regions in Seoul metropolitan city were collected and evaluated by established evaluation criteria. The coefficients affecting the price of apartment unit were made by way of linear multi-regression and put into Hedonic Price Model. The feasibility evaluation model for apartment was made and verified by data of remodelled apartment. The predicted results using suggested evaluation model coincide with actual apartment market situations.

After the late 70's, the apartment housing have been constructed numerously, but the apartment housing has been deteriorated and the maintenance cost has been increasingly upward as time goes by. Because of that, the reconstruction of the apartment housing is widespread in the late 90's. But as the owner, the congregation, is not an expert, there are many problems in the reconstruction projects. Thus, the necessity of the CM in the reconstruction project is getting higher, but the appropriate method for the application of the CM is not established yet. In this study, the CM work scope that is applicable in the reconstruction project is developed through the inquiry and interview to the experts. Especially, The work scope developed in this study is established to be adapted easily in the practical use for each project phase.

Korean government has launched a new public rental housing policy for younger generation suffering from instable housing conditions in CBD area. This paper is to analyze the financial feasibility of urban public rental housing projects, based on its cash flows. Urban rental housing projects should find out the way to reduce costs and to secure cheap land, because of the high land price in CBD area and complex relationship of legal rights. Project types are categorized by the land acquisition method and district characteristics. For 10 sample projects, financial feasibility was analyzed. Cash flows were calculated on the design plan and 16 scenarios were made by combining 4 important variables. The variables are increase rate of land price, increase rate of monthly rents, ratio of public and market rents, and the interest rate of National Housing Fund. The findings are as follows. Government land rent-type can reduce initial costs because it is not necessary to buy land. However, total NPV is lowered at the time of liquidation due to the land return. Private land acquisition-type require more initial costs. But the NPV at liquidation time increases with land disposal. To improve financial feasibility, acquisition-type should be preferred in high land-price area and rent-type should be preferred in low land-price area. Among influencing variables, the rate of increase in land price and the ratio of public and market rents turned out to be the most important. Although the ratio of public and market rents can be controllable, high ratio will cause the burden of tenants. Therefore, interest rate adjustment of National Housing Fund is more desirable.

The Korean housing supply have been provided by the Pre-construction sales system. The Pre-construction sales system contributed to large housing supply. But it followed by the market anomaly. Along the housing market is changing to tile market for consumers, it requires new policy and regulations. This market changes and needs to modify the policy make a discussion about introducing the Post-construction sales system. it concerns to change the time to sale. This paper analyzes the present feasibility study and makes a tool to predict construction cashflow considering changed sales point. The sales timing leads to decide the amount of financial costs in the construction project and that cost affects to the feasibility. The accurate cashflow prediction is required for a successful apartment construction delivery.
