err.. putra heights is a bit far off from damansara/pj.. if you stay in bukit jelutong, can easily exit to nkve straight to damansara toll.. but the damansara toll (near bandar utama) can be a bit hectic in the morning, coz ppl from tropicana, bu, kayu ara also using the road.

yes, the bukit jelutong toll used to be flooded after a heavy downpour.. but nowadays the condition is not as bad as last time coz they have improved the drainage. but if you can afford to buy houses in bukit jelutong (jln serambi area about RM400k min), i'm sure you can afford houses near damansara area which is closer to your workplace.
