Sohna mein property ke legal checks: what's your experience?

Kitne log actually RERA registration aur builder ka legal track record check karte hain Sohna mein, especially for new projects? I'm currently in a 2BHK aur ab 3BHK ya villa upgrade ka soch raha hoon. Hermitage Apartment (Emaar) type projects dekh raha tha, budget ₹2-3 Cr ke around hai. Pehle se home loan hai, so this is a much bigger commitment. Matlab, I'm really worried about any legal issues later on. Builder ka track record kaise verify karte hain? RERA website pe jo details hain, are they enough ya aur kuch dekhna chahiye? Title verification ke liye kya specific steps hain jo log often skip kar dete hain? Don't want any surprises after booking ya exit options pe impact ho. Just want to make sure mera investment safe rahe.
