Besides stupid and insane, you can add lazy in the list. With 750k, you can buy establish freehold landed properties that are much closer to KLCc . Think abt the petrol/toll money u can save and travel time to work, school or post office becos at the end , it is all abt money.
It appears that most buyers of Rimbayu made their decision based on these factors -

1.wow the house is brandnew and Hugh ,got lake view also.  love at first sight la,
2. The developers are all big and famous la, sure cannot die one this project
3. kota kemuning so successful, so Rimbayu sure successful also becos is the son of KK

The point is, don't just buy a new product becos it looks nice on surface.
