I am living in Puchong, it is a place mainly ownstay, not investment, or not yet. Recently more and more highrise projects, but it is lack of high class business centres, and traffic to PJ and KL are not as convenient. Nearby Sunway and Bukit Jalil demand does not spill over to Puchong, as those towns are having enough supply. So maybe is not the time for highrise yet.
