Affordable housing is a significant issue that has been a concern among Malaysians nowadays, especially in the middle-income group. The demand for housing has been increasing, and thus, the preferences of this group must be taken into consideration. The focus of this study is to identify the factors influencing house buyers in purchasing affordable housing among middle-income groups. The data was collected through a questionnaire survey distributed among school teachers in Malaysia. Two hundred twenty-five respondents returned the questionnaire, which was used for data analysis. Descriptive and statistical analysis was performed to analyze the data collected using Minitab software, Microsoft Excel, and Statistical Package for Social Science (SPSS). It revealed that house prices, location, and structure of housing had a significant relationship with the purchase decision of affordable housing among the middle-income group. In contrast, the neighbourhood factor had an insignificant relationship. It is also found that middle-income groups are aware of Malaysia’s affordable housing scheme and have a chance to be exposed to the scheme. Thus, this research will help the developers in developing housing schemes based on consumer’s orientation for future demand in Malaysia.
