Chandigarh investors: What to look for during site visits?

Budget finalised, loan pre-approved — now stuck on which project in Chandigarh. I'm eyeing Omaxe Celestia Royal for investment. My main concern is long-term construction quality. When doing site visits for under-construction flats, what should I actually look for beyond just the show flat? I'm thinking about future resale value and attracting good tenants down the line. Does visible quality during construction really indicate issues like cracks or seepage after a year or two? Honestly, not sure how to spot those early red flags. Any practical tips for assessing construction quality on site from an investor's perspective?
