Noida Extension mein property kaise shortlist karein?

Budget finalised, loan pre-approved — now stuck on which sector. Noida Extension mein property dekh raha hoon, but samajh nahi aa raha kahan se start karu shortlisting. Especially Prithvi Sales Corporation ke projects Atta Village ke paas kaise hain? Kya kisi ne wahan visit kiya hai? Site visit pe kya kya check karna chahiye jo builder usually nahi batate? First-time buyer hoon, honestly, thoda nervous bhi hoon. Koi experience share kar sakta hai?
