Urban redevelopment projects that transform the urban function and image of locally unwanted land use facilities can improve the quality of the living environment and also generate the expectation of a rise in real estate values in and around the project site. Prior studies show that urban development projects can activate the housing market and induce speculation. The release of plans or blueprints of such projects is often closely related to local elections. This paper examines the influence of the announcement of transforming locally unwanted land use on housing prices near Chang-dong Garage in Nowon-gu, Seoul. The study site, a facility considered a LULU, has been receiving public attention for the past two decades. Focusing on the initial announcement date of the development plan which coincides with local elections in 2010, 2014, and 2018, apartment sales data in Nowon-gu are examined using Difference-in-Difference Hedonic price models. The results showed that proximity to the garage location was negatively associated with the housing price in 2010, but its influence changed positively in the 2018 model. The findings imply that the influence of LULU on housing price can be changed by policy and environment development of a specific period and a refinement level of election pledges seem to be associated with the size of the influence.
