RERA projects are still full of hidden delays

₹1.5 Cr for a 3BHK in RERA Approved Projects area sounds okay, but I've seen builders play games. Even with RERA, always check their past projects for actual delivery delays and quality. Off the record, kuch RERA IDs mil jaate hain but ground pe kaam slow hota hai. What's your experience with actual possession timelines in these projects? Koi hidden clauses ya tricks pata hain?
