Noida Extension's Premium Homes: What should I watch out for?

₹90 lakh for a 2BHK in Premium Homes caught my eye. My kids have moved out, so my current big house feels empty. I'm looking to sell our old place and downsize to something manageable, a low-maintenance flat with an elevator, maybe near a good hospital. I've been checking out some projects in the Premium Homes corridor of Noida Extension. It looks promising, but honestly, I'm worried about hidden risks. Are there any red flags people have noticed there? Like, what about construction quality issues, or surprise charges later? Should I be concerned about builder reputation or future maintenance costs? Any experiences with specific projects or general advice on what to watch out for in that area would be super helpful.
