From broker to buyer, this is different

Since last Diwali, I've been checking projects in Noida Extension. In RE for years, I know the marketing spin, but buying for myself is different. Mahagun Mywoods Phase 3 dekh raha hoon. Construction quality ka real scene kya hai? Cracks, seepage issues after a year? Aur promised amenities milte hain ya bas brochure mein? Clubhouse, kids play area ki real usability kaisi hai?
