For subang 10-20++ years landed is pretty much not much appreaciation already as the house is old and second hand buyer know they need at least 100K to just renovation the house a new. Somemore mostly subang older houses are non gated security. So it won't go high too much. Like SS2 houses even though is big but max is around 400K sellling for double terrace.

Hartamas and Mont kiara are really over crowded with condos now a days. Sales are likely to go slow. Infact it is slower now already. Because jams and density.

However Sentul and Bangsar South seem to be the hotter cake now because it is just right beside KLCC vicinity. More favourable by investor because rental to foreigner is better. The closer to KLCC, the better.
