This research investigates and compares relationships between both locations and building
characteristics on rent of apartments and serviced apartments. The 3 case studies investigated are in
Bangkok CBD (Central Business Districts). Instead of using focused analysis on either location or
buildings with mass data analysis, the study applies case studies which allow the benefit of cross
investigation of both factors. The results show that to judge for rents, one cannot use either location or
number of amenity types alone. Moreover, there is a need to c9nsider maintenance, conditions,
buildings, and atmosphere of buildings at different price level as factors that can have influence on rent.
