salam farhan bhai,
i would suggest go for bahria. i bought a 10 marla plot in 2013 in bahria phase 4 opposite arena cinema for 36 lakh rupees and in one year sold the same plot for 82 lakh 
bahria is really the best society and trust me if there is any society which would last in pakistan thats bahria and the land rates will ONLY increase over time with the speed population and purchasing power is increasing.
close your eyes and go for bahria, you will never regret, my sister just bought 2 plots in bahria phase 8 ext last month.
