Builder delays: RERA effective hai Ghaziabad mein?

Not proud of this but I almost signed a builder-buyer agreement without properly reading the fine print. I'm currently in a 2BHK in Indirapuram, thinking of upgrading to a 3BHK in Crossings Republik. Sarvottam Group ka AU The Sunflower Phase 1 dekh raha hoon. Builder delay ka darr hai, especially near Delhi-Meerut Expressway projects. How effective is RERA agar builder late kare? Aur agreement mein kya red flags dekhne chahiye beyond possession date? ₹80L-₹1Cr budget hai, don't want to get stuck.
