Prestige City construction: Investors, what's your take?

Did a site visit to Prestige City last weekend, and honestly, construction quality dekh ke thoda darr lag raha hai. Fed up of renting yaar, finally taking the plunge but these under-construction projects mein itna compromise kyun? Walls mein thodi cracks dikhi, aur plumbing ka kaam bhi finished nahi lag raha tha. Builder ka track record theek hai, but on-site quality control ka kya? As an investor, resale value aur future maintenance cost ka tension hai. If basic construction hi weak hai, toh later on kitna kharcha aayega? Amenities toh dikha dete hain brochures mein, but yeh basic structure ka kya? Water supply aur tank capacity bhi check karna bhool gaya, but I'm worried about the long run. Anyone else faced this with under-construction projects, especially Prestige City? What should I specifically look for during site visits for quality?
