Noida mein builder ka legal track record kaise check karein?

EMI vs rent math finally makes sense, so Noida mein property dekh raha hoon. Builder ka legal track record kaise check karein, especially JM Housing jaise? RERA registration sirf portal pe dekhna enough hai kya? Aur title verification ke liye kya critical steps hain jo log often miss karte hain? Investor hoon, so exit options ke liye proper clarity chahiye.
