After selling our old home, Noida RERA checks are my biggest worry

Kids moved out, big Delhi house feels too much. Resale ho chuki hai, ab Noida mein manageable 2BHK/3BHK dekh rahe hain. Shree Homes Developer ka ek project pasand aaya. But RERA compliance aur builder ka track record dekh kar darr lagta hai. RERA portal pe check karna kaafi hai ya aur documents verify karne chahiye? RERA complaints effective hoti hain, ya bas paper pe hi hai sab?
