i think quite deeply on this topic recently because my wife wanted to move to a place nearer to KLCC.

Recently, my colleague who's husband is working in oil n gas thinks that travelling from kajang to KL takes so much time and toll. i think they ended up paying almost 2k for toll gas and parking to work in KLCC amonth. leave house at 630 and reach office at 8am. So, they sold their kajang house for more than double the price they paid in 2006, and moved to one of the older condos behind avenue k. D'mayang for about 700-750psf for 1600sf condo. now both of them can walk back to eat lunch and dinner. they said, they dont save money but save about 3hours of time from staying in the car to spending time with kids.

Drawback? childcare is expensive. avenue k top level is charging about 2k, and most are charging about 1k or above per kid. good thing they have a maid.
