My Gated Community property search — is it too late?

Budget finalised, loan pre-approved – ab Greater Noida mein property dekh raha hoon. I work in real estate, but buying for myself is different, yaar. 'Gated Community' area kaafi suna hai. Pehle lagta tha undervalued hai, but ab prices kafi upar gaye hain. Has it peaked already, ya abhi bhi upside hai? Konse sectors ya projects mein best value mil sakti hai for investment? Off the record opinions chahiye, no broker talk. ROI ke liye kya expect karna chahiye? Not sure if I should wait more...
