Years of renting, finally buying in Rajkot

Okay I'll be honest — I'm finally serious about buying in Rajkot after years of renting. Looking at Ansal Aastha Mig Zone, but builder ke legal track record aur RERA compliance pe confusion hai. Kaise verify karein builder ka past aur Ansal API ka RERA registration? Is RERA complaints process actually effective? Any advice on title verification in Rajkot, especially for projects near Kalawad Road?
