The objectives of this study is to analyze the effects of Seoul citizens’ housing characteristics on their preparation for old age and the expected monthly living expenses after retirement. For this purpose, binary and multinomial logistic regression analysis was conducted using Seoul Survey data. The analysis results are as follows. First, it was found that the housing type, occupancy type, and residence period in which the respondent currently resides have an effect on whether or not to retire. Second, the respondents who live in their own apartments, regardless of the period of residence, expect the highest monthly living expenses after retirement. Accordingly it was confirmed that the current housing characteristics of Seoul citizens have an effect on the preparation for old age and the expected cost of living after retirement.

‘Hillstate Beomgye Station Mobius’, which started in January 2017, is a representative case of conversion. The former Pyeongchon NC Department Store, located in the central commercial district, was converted to residential use and the development project was carried out. ‘Turn-to-Residence’, a good example of current real estate trends, serves as a manual for conversion development that will occur in the future by carefully dealing with the process of resolving problems caused by change of use. This study specifically discussed what kind of urban problems the project can contribute to and additional considerations for other uses that can achieve the effect of urban regeneration.

The purpose of this study is to analyze the factors affecting the successful bid rate targeting the Seoul-based knowledge industry center. First, based on the successful bid results of the knowledge industry center where the auction was completed in 5 courts in Seoul, multiple regression was conducted by classifying the influencing factors into auction characteristics, building characteristics, house-to-house characteristics, location characteristics, regional characteristics, and time-point characteristics. The multiple regression model was analyzed and compared with the linear model and the semilog model, respectively, and the residual scatterplot and P-P plot were tested to confirm normality. It provides implications for the auction market by analyzing the factors that affect the successful bid price of the knowledge industry center.

The purpose of this study is to compare and analyze the successful bid price rate of commercial facility sites in public land development projects for housing supply between southern and northern regions of Gyeonggi-do. The data are 255 lots in the southern region and 138 lots in the northern region for commercial land. Multiple regression analysis is conducted. The analysis result shows that there are distinguishing points such as floor area ratio, distance to main city center of seoul or subway station between both regions. The result of analysis show that the land, access, environmental factors that affect the winning price rate of commercial facility sites in public land development projects vary depending on the southern and northern regions of Gyeonggi-do. The southern region is most affected by the number of households in the district and The northern region is most affected by floor area ratio. In addition, the closest of distance from seoul's main city center affect both areas, but its direction appears to be reversed The implications could be used as a useful criterion for determining the price of the commercial land in new public land development projects for housing supply.

This study examines the determinants of housing tenure choice decisions of Millennials. Using KLIPS panel data from 2014 to 2020, a correlated random effects probit model and a fixed effects logit model were estimated to control for endogeneity problem associated with time-invariant unobserved heterogeneity. Estimation results showed that net wealth, relative housing cost, marital status of household heads were major determinants of housing tenure choice decisions. Permanent income, one of key variables on the housing tenure choice, was not significant, indicating that net wealth rather than income is more important to homeownership decisions of Millennials. However, the effect of net wealth on the probability of home owning was estimated to decrease over the observation period because the increase in net wealth could not catch up with the rise of housing price. A sharp decrease of the effect of net wealth on the probability of home owning in recent years was attributable to a dramatic increase in housing price and more stringent mortgage regulations.

This study was conducted to analyze the situation in which POSCO E&C failed the development project through various conflict situations while promoting the ‘Gang-nam Guryong Village’ urban development project to consider various factors and learn background knowledge related to the development project. POSCO E&C tried to develop Guryong Village, also known as “Potential Site of Gang-nam”, but it has difficulty in the progress of the project due to conflicts between residents and landlords, Gang-nam office and Seoul City Hall over the development method. In this situation, I would like to discuss what method would POSCO E&C to minimize the loss from the project and could have been considered. The purpose of this study is to consider basic questions such as “how to receive funds for the project?” and “how to proceed the project” and to understand background knowledge related to urban development projects such as “Finance through debt financing” and “Project financing (PF)”.

This study tried to examine the factors that affect the asset investment status and preference for foreigners in Korea and the differences between foreigners through empirical analysis. The survey period was conducted from March 01 to April 10, 2022, and an online and offline survey was conducted on foreigners staying at the time of the survey. For the analysis of the collected data, the SPSS 23.0 statistical package was used to verify the research task through descriptive statistics and logistic regression analysis. Foreigners have under average prospect for the Korea’s individual real estate and financial markets and investment preferences compared to their own countries and they have positive prospect for the growth of the Korean economy. Also it was found that there are differences between Asian and non-Asian groups in the factors affecting the asset investment preference of foreigners. In the case of real estate investment, the factors affecting the asset investment choice of the Asian group were more diverse. It is expected that the results of this study can be used as basic data for policy establishment and service provision for foreigners.

The housing market consumer index, the trends of sales price index and the auction bid price ratio are used as indicators to judge and the real estate market. Whereas there have been several studies that analyzed the relationship between the auction bid price ratio and the housing market consumer index, studies on the trends of sales price index are insufficient. This study examined the determinants of the auction bid price ratio in apartment auctions, and through empirical analysis with the housing market consumer index and the trends of sales price index, it tried to find out how the two indices affect the real estate auction market. The study set the time scope to 6 years between January, 2015 and December, 2020 and the space scope to Gangnam-gu, Seocho-gu, and Songpa-gu of Seoul. Independent variables were set as housing market, auction, local, location, article, and time of a successful bid. The analysis method used multiple linear regression analysis using a hedonic price model. As a result of analysis, it was found that the housing market consumer index and the trends of sales price index have a positive effect on the auction bid price ratio. Moreover, the failure in bidding, the land registration, the tenants with opposing power, and the lien have a negative effect on the auction bid price ratio, and the number of bidders has a positive effect on the auction bid price ratio. In addition, more than 30 years of elapsed years, small and medium sized space, and medium-large sized space have a positive effect on the auction bid price ratio, and the timepoint of 2018, 2019, and 2020 were found to have a positive effect on the auction bid price ratio. It is expected that auction bidders will be able to make rational decisions by judging and predicting the situation of the real estate market and auction market.
