At the present moment, there is no ready 1 bedroom apt. that is available for 620,000-650,000 except IC and lowest priced apt. available in other localaties might be near to 800,000.
So after 6 months when prices for the non-ready 1 bedroom Apt. in other areas have reached above 950,000 and probably after 6 months IC will be landscaped,all apts. will be fully occupied, there will be more shops & facilities and might be const. for the Nakheel mall also get started,, then its not unrealistic for IC bedroom apt to sell at 800,000.

This is my point of view.....may be I am wrong, please correct me.
