Delhi buyers: What's your secret site visit checklist?

Under-construction site visits are usually just a sales pitch, honestly. I'm in real estate but buying for myself, so I know the drill. When checking Maitri Apartments ya koi bhi Delhi project, don't just see the sample flat. Go to the actual floor. Look for straight columns, no visible cracks in plaster work pre-paint. Ask the masons, 'bhaiyya, yeh kaam sahi se hua hai kya?' off the record. Sometimes they'll tell you stuff sales won't. Hope this helps someone avoid future headaches with seepage ya fittings.
