Bheka Saiyidaan? F-11 sector Islamabad

Is Bheka Saiyidaan a village in F-11? Are property prices of F-11 lower than Ff-10 because of this Bheka Saiyidaan or because F-11 is next to Golra? What is the situation of crime in F-11? is F-11 really considered a posh or nice to live in sector because of the above mentioned issues? And why are the prices to high compared to G-9, 10, 11 if they have problems like Bheka Saiyidaan and Golra/crime in F-11 ?

Actually I’m confused about sector F-11 so just trying to get expert opinions here.
