Faridabad investment: What am I missing on quality?

What are the *real* red flags to watch out for during final snagging at Goyal Luxury Floors? I work in real estate, but for my own investment, I'm extra cautious. Builders always promise the moon, especially with amenities and finish quality. Sach batao, kitna difference hota hai between brochure aur reality mein? I'm worried about construction quality issues like seepage ya cracks jo ek saal baad dikhte hain. Is the plumbing and electrical work reliable? Also, amenities jo dikhate hain like clubhouse facilities, woh actually functional hain ya bas show-piece? Power backup ka kya scene hai – full flat ya sirf common areas? Any specific tips for a thorough check before taking possession? Want to avoid future maintenance headaches. Off the record, what builders don't tell you about material quality?
