Noida Ext investment: Legal checks are a total maze

Okay, I'll be honest — buying property in Noida Extension has me totally confused with all the legal stuff. I'm looking at some investment options, maybe a 2BHK around ₹70L-₹80L, thinking long-term for Jewar Airport appreciation. Projects like Nimbus The Golden Palms sound good, but builder ka track record kaise check karein properly? RERA registration to sab dikhate hain, but is that enough? Kya builder ka past record, like project delays or legal issues, online mil jaata hai? Aur title verification ke liye kya steps hain jo log aksar miss kar dete hain? I don't want to get stuck in some legal mess later. Koi experienced bande help kar do please.
