While the Korean government has implemented various housing policies to achieve the goal of a stable real estate market, not sufficient assessment was made on policy measures. In particular, not many studies assessed the impact of the housing policies on new apartments as it is difficult to access sales rate data. This paper examines the effects of housing demand-side policies implemented to stabilize the housing market following the 2008 global financial crisis on new apartment sales by analyzing new apartment unsold rates, and draws policy implications. We analyze at various housing policies which may have some effects on unsold rates of new apartment, and find that eased regulations on LTV cap, resale of purchase right, and transfer tax have had not sufficient effect on unsold rates of new apartments. When all policy events are combined, their explanatory power is a mere 2.2%. However, when individual policy event was analyzed for its impact on unsold rates, the relaxed regulation on purchase right resale has shown the biggest impact with the explanatory power of 83.5%.
