Ansal Aastha Mig Zone — my legal doubts

₹80 lakh for a 3BHK near Kalawad Road is my budget. I'm looking at Ansal Aastha Mig Zone. Builder Ansal API ka legal track record kaise check karein? RERA registration dikha rahe hain, but title verification aur encumbrance certificate ke liye kya steps hain? Not sure if RERA complaints Rajkot mein actually effective hain. Investment safe hai kya?
