Recently, socio-economic environment surrounding the social housing market has been changed. The neo-liberal trend in political environment has been cutting the direct subsidies and funding for the social housing. To improve efficiency of social housing management, governments try to secure funding by the participation of the private sector. This study aims to deliver comparative analysis on ownership transfer scheme among social housing markets of UK, Germany, the Netherlands and Hong Kong. These countries allowed social housing privatization by individual sale to tenants or stock transfers from public sectors to private sectors for decades under the neo-liberalism. These new ownership schemes of social housing, in the short term, could be able to secure additional funding for social welfare and improving the physical environment. However, in the long term, the public sector have to pay more to solve social and community problems of tenants of former social housing. Some countries, such as Germany and UK, are required to deliver more social housings for solving the long waiting list problem caused by social housing stock reduction. Thus, it should be take cautious stance to introduce such a new ownership scheme in social housing.
