Abstract

In this study, actual contract based indices for non-apartment rental market was estimated which had not been attempted before. At this time, in the case of the monthly rent index, the pure monthly rent index was estimated using data with a deposit ratio of 300 times or less compared to the monthly rent, and both the monthly rent index and the data rolling method were used to improve the stability of the index. As a result, it was confirmed that although there may be some differences depending on the same-house assumption, if sufficient data are collected and the data are properly cleaned in the future, it is possible to estimate a stable chonsei and monthly rent index for non-apartment rental markets.
 In addition, in order to confirm the changes in the housing rental market after the lease regulation and to control the possibility of showing distorted market information, the chonsei and monthly rent index was estimated using only new contract data. Although the accumulated data series after the lease regulation is short, there is a limit to determining, but there is a difference in rent price level and fluctuation between new contracts and renewal contracts, and it is possible to estimate a rent index that shows the actual price movement.
