Wave Veridia: My snagging and quality reality check

Since January I've been shortlisting flats in this city. I work in real estate, so I know what builders don't tell you, but buying for myself is a whole different ballgame. I'm seriously looking at Wave Veridia in Ghaziabad and trying to get past the marketing fluff. My biggest concern is snagging and the actual construction quality. After possession, what's the reality? Are people finding cracks, seepage, or fitting issues within the first year? What's the builder's response time like for these problems? Also, what about the day-to-day stuff? Is the water supply reliable, or do you face tanker dependency often? And how are the elevators – any frequent breakdowns, and how quickly does maintenance respond? Off the record, what's the community's honest take?
