Yes its a good buy. You'll need to negotiate the price big time as the prices are on peak since last few weeks. And before buying do visit the location to get an idea of real situation and keep these concerns in your mind:
-tender for construction is issued but fgechs has not taken the posession yet coz only 25% of the affectees have been paid the compensation. So development work cannot be started before FGECHS takes the posession of land.
-by the time g14/3,2 will develop, its likely that cda would announce new sectors like c13, c14 and c15 so it might affect its prices in the future. But of course, you know the pace of cda if they announce it tomorrow will take a decade to start the development.
