Possession of R block is expected in 2 years.
You should hold the plot if it is having a good location other wise you should sell it now.
There is some private land in between DHA phase 9 town and prism R block.
Please feel free to contact us for more details
I would just like to add that the minimum period we expect for possession is 2 years however it can be delayed upto 3 to 4 years.
In addition after possession you can expect a couple of years delay before the houses start constructing.
Before you buy kindly consider carefully as no one can give you any precise time lines not even DHA.
