서울시 단독주택 경매 낙찰결정요인 분석

김정선(Kim Jung Sun),유정석(Yu Jung Suk) 한국부동산학회 2015 不動産學報 Vol.60 No.-

부동산거래는 공급자와 수요자간 협상이 요구되는 일반시장과 수요자간 경쟁에 의해 형성되는 경매시장으로 구분된다. 최근 부동산 경매시장은 경기침체와 소득저하 등으로 공급이 증가하였고, 과거에 비해 부동산경매와 관련한 정보의 획득이 용이하고 시세보다 저렴한 가격에 부동산을 구입할 수 있다는 장점으로 수요가 증가하고 있다. 본 연구는 최근 양적 및 질적으로 확대되고 있는 부동산 경매시장에 대하여 다양한 정보를 제공하고자 로지스틱 회귀분석을 실시하여 경매 낙찰결정요인을 분석하였다. 실증분석은 2014년 1월부터 12월까지의 서울시 소재 주거용부동산 중 단독주택만을 기준으로 하였으며, 분석결과 낙찰확률을 증가시키는 변수는 개발여부, 낙찰가비율, 유찰횟수이며, 낙찰확률을 감소시키는 변수는 건물이용, ln감정가액, 임차인유무, 경매범위, 인수권리유무 등으로 나타났다. 1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to closely examine and provide statistical analysis on what variables and how they determine the success or failure of the auction of single houses. (2) RESEARCH METHOD The subject of examination in this research is restricted to single houses located in Seoul which were up at public auctions in 2014. For public bidding has a distinct feature that it is held on a specific day and its success and failure is determined that day, Logistics Regression Analysis model is used for examination. (3) RESEARCH FINDINGS Chief findings of this research seem to be consistent and plausible enough to provide meaningful results for the auction participants so as to enhance their predictability and make a contribution to their wise decision-making. 2. RESULTS The results of this study are as follows. 1) The variables that elevate the probability of success in bidding are found to be the followings: Whether the real property is repaired or well developed, a ratio of final contract price to the official evaluation price of the property and the number of biddings performed. 2) The variables that reduce the probability of success in bidding are found to be the followings: Whether the residential real property is used as single housing or multi-unit housing, the log value of official evaluation price of the property at the start of its auction, whether there is a tenant of the house, whether it is a stake auction and whether the final successful bidder should take over burden such as lien and legally protected superficies.

1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to pioneer new interpretational approach to the study on the recognition of priority performance and opposing power restriction of lien. It is expected that the result of this study could contribute greatly to solve the uncertainty and disorder stemmed from lien in real estate auction markets. (2) RESEARCH METHOD This study was focused on theory analysis and alternative re-interpretation of provisions under the pre-existing laws. We went back to the ancient legal principles in Roman laws including exceptio doli and retentio in order to inquire into the origin and development of lien. We analyzed lots of precedent studies and materials which are related to our topic. This study examined the substantial and procedural laws in force in order to grasp the contents of lien and real estate auction under the current regulations. This study centered on the new interpretation of related laws via systematic linking of the substantial law(Civil Law) and the procedural law(Civil Execution Law) as opposed to the prevailing opinions. (3) RESEARCH FINDINGS Lien influences on the performance of real estate auctions. It turns down the rate of sold quantities and sold prices. The most important causes of this negative effect are uncertainty of auction procedure and priority disorder resulted from non- systematic interpretation about lien based on the dogmatic logics. 2. RESULTS This study presents an interpretational method from the standpoint of new approach to solve the nuisance of lien in real estate auctions. It is strongly suggested that the prevailing opinions on priority performance and opposing power are to be modified as follows: 1)It should be recognized that lien also holds the qualification for priority performance, same as other typical security rights including mortgage and pledge. 2)The opposing power of lien should be subject to restriction according to the opposing power among the rights.

실거래가지수 연동금리 모기지 도입효과 분석

This study analyzes the ILM (Market price Index-Linked Mortgage) which links the market price index which reflects the housing market price with the mortgage loan rate. ILM is one of the mortgage risk management measures to which the domestic housing financial market is structurally exposed under the economic mechanism of the negative equilibrium relationship between the mortgage and the house price. Regarding the ILM adjusted mortgage rate estimation, unlike the preceding studies, the volatility mitigation effect was measured applying the first time lag when the negative equilibrium relationship starts, not the time lag when the negative equilibrium relationship is at a maximum. Also, there is three months time lag between the housing transactions and the market price index publication in Busan, Gwangju and Daejeon where the ILM was most effective. The analysis through the index prediction considering the estimated error still showed the volatility mitigation effect. According to this study, it was found that the volatility of mortgage loan rate was mitigated without the risk of index prediction and estimated error for the first time lag when the negative equilibrium relationship starts was applied, not the time lag when the negative equilibrium relationship was at a maximum. However, with three months time lag between the housing transactions and the market price index publication, the management complementary measures like the measures to shorten the reporting period to 15~30 days can help reduce risks arising from the index prediction, In addition, since the risk-return trade-off relationship represents the level of borrowers utility, it is questionable that the utility increase of borrowers is an essential precondition for ILM introduction. However, ILM can be applied to the low income area to increase the utility of borrowers and it has more meaning as political adoption in terms of equilibrium and residential welfare.

본 연구에서는 한미 리츠시장을 유형별로 구분하여 위험조정후 투자성과를 위험조정모형(RAM) 및 보완모형을 통해 비교분석하였다. 실증분석결과 첫째, 존속기간이 없는 미국 리츠시장은 투자성과 면에서 국제 금융위기 전후가 매우 상이한 모습을 보인 반면 존속기한이 있는 국내 리츠시장의 경우 국제금융위기 이후보다 리츠의 청산시기가 집중되어 매각차익에 대한 기대가 높았던 국제금융위기 동안에 오히려 투자성과가 높았다. 둘째, 미국 리츠의 경우 전 기간에 걸쳐 1을 전후한 베타값을 보이면서 국내 리츠의 베타값보다 휠씬 높아 국내 리츠시장에 비해 고위험-고수익의 특성을 보였다. 셋째, 보완모형을 통해 한미간 유형별 리츠의 투자성과를 비교분석한 결과 전반적으로 미국의 경우 국제금융위기로부터 빠른 회복 속도를 보였던 반면 한국은 국제금융위기의 여파에 다소 둔감한 반응을 보였음을 확인할 수 있었다. 1.
