Ghaziabad RERA compliance feels like a grey area.

I work in real estate, but buying my own flat, maybe in Jain Homes 02, has me anxious about legalities. Builder ka track record check kar raha hoon but RERA site pe details adhoori lag rahi hain. OC delay ka risk kitna hai? Should I trust the RERA portal for real status updates, ya kuch aur verify karna padega? Kya RERA complaints actually kaam karti hain, or it's just on paper? Confused.
