Inadequacies in mechanisms and policies, loose management, and a lack of affordable housing are the main reasons behind the growth of “mini apartments” in major cities. Most buyers are individuals and households who do not have the economic means to buy a regular apartment. Unlocking the supply of social housing and affordable commercial housing is key to resolving the problems. In order to improve the supply of these types of products, it is necessary to add special mechanisms and policies to create maximum conditions for investors.
