Gurugram Metro: Hidden gems near extension?

Gurugram Metro extension (SPR) ka kya scene hai for price appreciation? Main abhi DLF Phase 2 mein shift hua hoon, connectivity yahaan kaafi sahi hai. But long-term investment ke liye soch raha hoon. SPR ke along kaun se sectors mein abhi bhi 'affordable' deals mil sakti hain, ya sab already priced in ho gaya hai? Especially near Sector 80-90. Log bolte hain Godrej aur Emaar ke projects expensive hain, but kuch hidden gems hain kya? Any tips to find good value?
