A handover unit almost always looks clean at first glance. But open the cabinets, run a finger along the window tracks, or look closely at the AC vents, and the real condition shows — fine construction dust, sand and residue that a quick developer wipe-down never reached.

It’s most common in brand-new properties near active construction, where fine dust keeps settling long after the surfaces look finished. “New” doesn’t mean “already clean” — it means the mess is just out of sight.
