Purchasing an apartment is an important decision of the residents. Unlike the previous research mainly focusing on housing choice based on the socio-economic and environmental factors, this study concentrates on the early stage of apartment choice. It means the apartment buyers need to consider many factors, including financial conditions, internal designs, legal conditions, external landscape, environment, etc., in making the purchase decision. Aiming at the fundamental problem of family apartment-purchase decision, this study attempted to create a multi-criteria apartment choice model based on the fuzzy Analytic Hierarchy Process (AHP). Notably, a hierarchical chart of apartment choice is developed based on nine critical factors, i.e., housing amenities; internal housing design; indoor environment, quality and safety; exterior design and landscape; social infrastructure; legal conditions; capability of an investor; Fengshui; and financial factor. By conducting the questionnaire survey with 45 experts working in the real estate companies in Vietnam, this study applied the fuzzy AHP to solve complex decision problems and rank the alternative housing choice. In addition, the findings enable us to propose some feasible solutions for managerial managers and government authorities to improve the real estate market's attractiveness.
