Hidden signs of future headaches in under-construction projects

Visited Parsvnath Platinum last weekend, I'm finally taking the plunge, fed up of renting. Landlord ne phir rent badha diya. Under-construction projects mein quality kaise judge karte hain yaar? Site par toh sab theek lagta hai, but baad mein cracks, seepage, fittings ke issues sunte hain. Investor perspective se, yeh sab resale value aur tenant attraction par kitna impact karta hai? Kya builders ki initial construction quality se future maintenance costs ka andaza lagaya ja sakta hai? Aur elevators, water supply jaise basic amenities ki long-term quality bhi kitni important hai. Kisi ko Parsvnath Platinum ka track record pata hai in these areas? Should I be looking for specific things during site visits that signal long-term problems?
