This document is based on the rental housing market in Thailand and in Bangkok, in particular, is multifaceted. It serves many groups with different products and several sources of financing. Some experts have argued that it is an efficient market, with little or no need for governmental intervention. Others note that there are still a great many people in need, particularly those who live in slums or in squatter settlements. The responsibility for the development and financing of rental housing resides in a number of entities. Both the public and private sectors are involved with relatively clearly defined roles and in a way that matches the segmentation of the market itself. The market appears to work efficiently on the upper and middle ends. Even on the lower end, some argue that rental housing is affordable and that it meets the needs of the consumers. However, the greatest need is in the lower end of the market, particularly for those living in slums and in squatters’ settlements. Here the limitations of the nation’s housing policies can be seen. Although there have been positive efforts to resolve this difficult problem, not enough resources have been dedicated to its resolution.
