Brother Syed Ibrahim,
Thanks for your valuable suggestion and input on this matter which is really important for you.
Now i finally reach to conclusion as an outcome of my evaluation and study (so for). I have two options available in my budget.
1) B-17 E block - as this block will be developed before d block and hope so that development will be completed in 2 years time. Only drawback is stone crushing Margalla Hills and allergy may disturb to resident produced by the dust.
2) PECHS - I visited this place on Sunday, they have very low development standard and plot prices are comparatively high. I personally think it will take 2 - 3 years to settle this place and only charm is shifting of new air port. They have started k block on installment and claims (Mian Brothers) that development in k block will be completed in maximum six months.
Rest Allah SWT knows better. I really appreciate your help and favor. May Allah SWT grant you reward for this, ameen. As you are investing your time and experience for betterment of general public.
Please comment if you think something is better for us e.e. People like me who can arrange maximum 10-12 lac and wants to enjoy good place for them and family in next 2 years time for constructions.
Thanks,
Qaiser
