✓Actual measured surface area versus the advertised figure.
✓Finishing quality and materials — not just whether it looks good on the day, but whether it will hold up in 12 months.
✓Workmanship quality — tiling joints, plastering, ceiling lines, and the details that show poor execution once the building has settled.
✓Fissures in walls or ceilings — early signs of structural movement or rushed finishing that will worsen over time.
✓Humidity control and ventilation — poor insulation and inadequate airflow show up after you buy, not before.
✓Paint quality and wall finishing — a new build looks clean in summer; by winter you can see exactly what the materials were.
✓Sound insulation between units — walls, floors, and ceilings.
✓State of common areas: lobby, stairwells, exterior facade, parking.
✓Street noise, traffic, and the immediate neighbourhood — not just at the time of the visit.
✓Unit orientation — whether it faces a courtyard, the street, or another building, and what that means for airflow, natural light, and privacy.
✓Water pressure and drainage — basic infrastructure that varies significantly between buildings and is rarely mentioned in a sales conversation.
✓Electrical installation quality — adequate sockets, circuit capacity, and whether the work was done properly rather than to the minimum.
✓Developer track record — what they have delivered before, when, and whether it matched what was promised.
✓Permit status, payment schedule structure, and what written documentation you receive at each stage.
