Investing in DHA( Khi, Lhr or Isb), Bahria Town, Naval Housing or Air Force Housing is not a bad idea. Relatively, there process is straight forward, hassle free and your property is safe compare to other areas in Pakistan.
Do you see the property prices going up in the future there? I just dont want to invest and then sell at the same price later. If that would be the case than I would rather buy something in UK.
I have family there who can take care of the property, so that's not an issue.
