After the explanation from sales staff I think the price still ok. According to them, the house is fully extended and the build up up to 2519sqft. Mean around RM295 psft. Normally the extension fee need at least RM80k. So after minus everything I think around RMRM660k. And it's gated n guarded! Nowadays safety is the most important concern. This is how the sales person convince me, so I bought a unit there...
