I came to term with this dilemma 2 years ago. my wife and i works in KLCC area, and the industries that we are in, exist in big numbers around KLCC and bukit bintang area.

and we bought an old property around this area also so that we can walk to work. rather than spending 3 hours in the car daily *well most of the time we went home at 8pm to escape traffic, now can be home at 6pm.

its about lifestyle choice really. old condo might not see big jump in appreciation compared to landed because the price has stabilized.

Dont worry about cheras, i've lived in batu 9 cheras long enough to know that even with MRT completed, traffic problem is unlikely to be solved there.

if ppl stay near where they work. no need for lrt maa.. haha
