Renting out, eyeing SPR now

Fed up of renting for years, finally taking the plunge. Landlord ne rent phir badha diya, ab bas! I'm looking at Gurugram, especially the Southern Peripheral Road. Log kehte hain it's a great investment, but I'm wondering if it's already peaked? Ya abhi bhi undervalued hai? Should I consider sectors like 79, 81, or even further down? Kya wahan abhi bhi ROI potential hai for a 2BHK? Or am I too late? Any specific projects in SPR that you guys think still offer good value, ya sab over-priced ho gaya hai?
