G-15 plot price islamabad

What are current market rates for g-15 40’x 80’ and 50’ x 90’ in all sectors both corner and none corner.

I think 40*80 non-corner 11.5 million and corner 13 million.

50*90 non corner 12.5-13 million and corner 14.5 million

How about 30x60 main service road/ corner plots?

Corner as told by someone in some other forum i think is around 9 million. I think should be around 8.5 max unless it is both a corner + service road plot
