Where to invest in Islamabad? 20-50 lac for 2 years or less

Title says it all.

I'm looking at GT road societies; b17, e16, f15, etc but i dont see alot of potential.

On the other hand, if you look at the west side; pwd, dha, bahria, naval anchorage etc there isnt alot of potential as investment either.

Any thoughts?

B-17 or d-17 both good options
