Think Location
Location still the most important factor when buying, this is an high end condo surrounded with bungalows and semi detach up market neighborhood stanproperty.com/new-launch , hardly any traffic congestion , convenience with amenities nearby and easy access with many connecting roads.
Rental Return
In this past few years, is harder to get return of 4% or above for any new cheap condo as the price is high and demand is less with surplus of condos in some locations but it might not be so in future as price most likely going up as land are scarcely available and it will be further away.
Might not be the case for this high end condo since this area still consider limited number of condo and demand is always there for up market condo .
Available For Sale
Only a handful are available stanproperty.com/property/Aira Residence for sale-residence-damansara-heights2 for sale knowing the limited number of condos, the strategic location coupe with the luxury and low density which hard to come by, more so in this location where you want to live in peace rather than urban vibrance city life.
Conclusion
Is always your own preference but with reference with experience agent or investors or friends will give some decent advice to get your unit.
