|In this paper, we analysed whether the liabilities of financial institutions for the purpose of receiving additional collateral loan is increased when the capital gains in the ownership housing has occurred. We used in the 2014 Housing Survey data for this analysis. As a result, contrary to expectations, the more capital gain is large, the debt of financial institutions was found that the decrease. If you have a capital gain to be able to cash, it is possible to reduce the debt of financial institutions. However there is no way to be able to cash the ownership housing. This is a kind of puzzle. To solve the puzzle, we conducted analysis of apartment dwellers. If the capital gain was generated, although debt financial institutions increased. But it was not statistically significant. On the other hand, as a result of try the analysis for non-apartment resident, if the capital gain has occurred, it was found that the debt of financial institutions is reduced. In the case of non-apartment residents, it is possible to rent some space of your own home. When the value of the house rises, it is possible to receive an additional housing deposit. It is possible to repay the debt of financial institutions as a security deposit, which was further received. Exactly this reason, in the case of a non-apartment resident, if the capital gain occurs, it is expected to debt of financial institutions is reduced. That is, in the case of our country, even if the value of owning a house is raised, using the additional collateral loan, than increase the debt of financial institutions, in response to the gold, it seems to reduce the debt of financial institutions.
