Eco Ardence is out as I want to be closer to the Chinese Taipei International school, closer to nearby beaches and closer to the KLIA airport for my ‘ taxi’/flight back to HK or nearby Singapore.
Besides, I really prefer Klang Valley south vs Klang valley north as my business associates feel the South side has more future potential and various developments e.g. HSR , ECRL etc

Thanks for the tips on ES house layout with one kitchen only.
Actually, in terms of house layout, my architect wife really likes the Tropicana Dalia semi D or the Cheria Type B semi D. Those have the spacious open floor plan feel which are really popular nowadays. The queen of the house (my wife) likes it as she can monitor everything on the ground floor from the dry or wet kitchen. Hahaha. Coming from someone who lives in a 1500sqft condo in HK, the 3200sqft Cheria maybe just nice for a family of 4. E.g. not too scarily big, nor too small. Also,  with Tropicana Cheria or Dalia, my teenage son might be able to take a quick 5-10 minutes walk to school/Tenby (if he goes there). That may be a good way for us to train him to be independent. E.g. walk to school, walk to shop to buy food etc. Unfortunately, those homes are not available for rent at the moment. I may check those out later when I am ready to buy.

My wife is Malaysian. So the 2 million rule does not apply to us.

Yes. My business associate is a smart man eg cashing out of Setia Eco Park capital appreciation and moving on to newer, nicer architecture home at ES.  I guess he don’t want to take all the hassle of maintaining his old Setia Eco-park house.
