Sohna property: The legal checks nobody talks about

Sohna mein property dekh raha hoon, CyberHub se thoda distance hai but future potential lag raha. Tata Housing ke plans dekhe hain, but honestly, legal verification steps pe atak gaya hoon. First-time buyer hoon, toh RERA check toh pata hai, par title search, encumbrance certificate, ye sab kaise karte hain? Koi bata sakta hai kya important legal red flags hote hain jo builder nahi batayega? Parents keh rahe hain dhyaan se dekhna, par exact kya, samajh nahi aa raha.
