What nobody tells you about Hyderabad builder-buyer agreements

Builder-buyer agreements in Hyderabad are a total trap, honestly. Fed up of renting, landlord raised rent again, so finally taking the plunge in Gachibowli. I was looking at Salarpuria Sattva's Sattva Lake Ridge, and the BBA clauses about possession delays seem so one-sided. It feels like they can delay for years and we just have to wait. Kya RERA actually help karta hai when builders default? And how do you properly check RERA registration details beyond just the number? Are there specific red flags to look for in the RERA portal itself, yaar?
