The aim of this study is to examine the continuity of private property rights after an urban regeneration project. There may be several social, economic and environmental parameters on the preferences about property rights. The land sizes of property owners are one of the most important economic parameters. Therefore, after the first urban regeneration project in Kocaeli, the relationship between local people's land sizes and their residence preferences is analyzed by using a geographic relational database and various regression models. Consequently, it is understood that there is a high correlation between land sizes and exchange preferences in the case project.
