Selling big house, my snagging hack for Noida Extension

Did a site visit to Deepak Green Residency last Saturday and it got me thinking. My kids have moved out, so I'm selling our big house for something manageable, low-maintenance in Noida Extension. On paper, Deepak Green looks good. But during the visit, I saw a few small finishing issues in a ready flat – like a corner of plaster peeling, slight crack near a window frame. My tip: always check a *real* unit, not just the sample flat. These small 'snags' can become big headaches later. For me, a reliable elevator is key. How's the elevator quality and maintenance response in Deepak Green Residency, especially during peak hours? Builders kitna time lete hain to fix these small issues before possession? Yaar, after a certain age, convenience matters most. Any advice on ensuring a solid snag-list resolution before taking handover?
