Downtown 66: Is it a good investment for resale?

₹5.17 Cr for Downtown 66 feels like a big jump for my first investment. Gurugram mein property lena hai but thoda nervous hoon. Downtown 66 dekh raha hoon, Sector 66 mein. Ongoing project hai, toh under-construction risk kaafi lag raha hai. Builder ka track record kaisa hai, will they deliver on time? Possession timeline kya expect kar sakte hain? Aur iska resale market kaisa hai? Matlab, 5-7 saal mein exit karna ho toh buyers milenge easily? Kahin ghost society toh nahi ban jayegi agar investor ratio bahut high hai? Gurugram mein aise projects ka resale value acha rehta hai kya? Any thoughts ya experiences on this project? Parents bolte hain ready-to-move lo but budget mein nahi aa raha.
