You should go to the thread for Sunway Mont to read up and do some research on the development itself. There are abundance of review for most Mont Kiara properties that will help you get a better idea.

Just my 2 cent on the issue, current lands in MK are scarce and the recent developer unit locations are leaving alot to be desired. And prices are not actually reflecting on current market as they are priced for the future.

If your uncle is looking for a property for own stay, my suggestion is to look at subsale properties as well. In addition to be able to see the actual property close up and access the condition, the prices of subsale property might sometime be much cheaper than what developers may be able to offer.

But then if your uncle insists on getting something brand new then developer units is the way to go. Alot of research needed to be done to make sure he is comfortable with the risks to avoid being shortchanged in the long run.
