subsale cannot judge the price solely on floor level. many other factors like unit condition. major renovation vs no renovation. partial furnished vs full furnished. unit views, neighbours, etc.

if all factors list above the same. then higher floor unit will priced higher compare to lower floor.

for undercon property, it is normal practice 1 level increase 1k. some property increase RM500 per floor. some even RM3k per floor depending on the developer. same size. same layout. same viewing. just different floor level. yes, the higher the unit, more expensive you need to pay.
