Farhan sb,
They will give possession of DHA Homes and may be one or two adjacent blocks.. They have never said that they will give possession in whole..
Since DHA Valley have only 40-50% land so they are in no position to give possession of all blocks.. Due to unable to buy land, they have given this second option to investors to move somewhere else where they can at least hope..
I personally thing, if someone plot is in DHA Home surrounding block or overseas then wait otherwise move.. Because DHA and Bahria are in no position or mood to buy further land for valley..
If people have plot in sectors for which no land is purchased then they should move now and forget about delay otherwise they will be in more delay
Keep this fact in view, valley has only 40-50%land...
