My Noida Extension home hunt: Even I'm confused

Honestly, I work in real estate, but buying my own place in Noida Extension is a different ballgame. I'm looking at Real Shree Shyam Villas (ongoing) versus Deepak Green Residency (ready). Shyam Villas mein possession delay ka darr hai, but Deepak Green ki total cost of ownership, including all hidden charges, kitni upar jaati hai? Ready-to-move ka premium worth it hai kya? Any actual experiences with these projects on final costs or unexpected issues?
