통합공공임대주택 도입에 따른 서울시 공공임대주택의 주거비 추계 연구

초록

As part of an empirical study on the impacts of the Integrated Public Rental Housing (IPRH) system, this study estimates the projected rents and security deposits for IPRH in Seoul—where the system has not yet been introduced on a full scale—using data from existing public rental housing residents. By utilizing actual market rental prices published by the Seoul Metropolitan Government and data on the income, housing area, and household size of current and former residents extracted from the Seoul Public Rental Housing Resident Panel Survey, we estimated standard security deposits, standard rents, rent-to-income ratios (RIR), and variations across autonomous districts. The summarized results are as follows: First, the introduction of the IPRH system is expected to significantly increase the standard security deposits and standard rents for future public rental housing supplied in Seoul. Second, compared to the IPRH currently supplied outside of Seoul, it is projected that residents in Seoul will bear a rent burden 3 to 4 times higher than those in other regions. Third, the most influential variable in calculating standard security deposits and rents was the market rental price, which resulted in a substantial deviation between districts with high recent transaction volumes and prices and other districts. Fourth, when converted to the IPRH standard rent, the majority of existing public rental housing residents recorded an RIR exceeding 25%. This implies an urgent need to devise measures, such as applying adjustment coefficients, to lower rents for the IPRH to be introduced in Seoul. In conclusion, the findings indicate that the introduction of the IPRH system will lead to a substantial increase in rents and security deposits in Seoul, accompanied by significant inter-district disparities. Although IPRH is undoubtedly an advanced public housing policy aimed at addressing housing problems in Korean society, its successful implementation requires careful consideration of regional characteristics, evolving housing demand patterns, and socio-economic factors, along with continuous institutional improvements.
