RERA is just a paper tiger for Bangalore builders

Visited Olympia Enchante last weekend, MC Builders ka project hai. Currently in a 2BHK in Whitefield, thinking of upgrading to a 3BHK near Sarjapur Road, budget ₹1.8 Cr tak. Is the price jump worth it? Biggest tension hai builder delays, yaar. Suna hai RERA hai but kitna effective hai jab developer possession late karta hai, especially with projects around Peripheral Ring Road? What are our real legal options agar builder time pe nahi deta? Also, encumbrance certificate kitna important hai? Log bolte hain bina verify kiye payment mat karna. Kya kya check karna chahiye usmein, before signing anything? And RERA registration kaise confirm karte hain online? Koi hidden red flags bhi hote hain kya? Already home loan hai, don't want to get stuck in legal issues.
