External shared areas fail slowly and then all at once
Nobody notices a driveway getting gradually worse. Litter accumulates against fences, leaves collect in corners, the bin bay develops staining and odour, and cardboard blows around after each collection. Each week is marginally worse than the last until a tenant complains or a prospective occupier walks through. By that point the recovery is a project rather than a routine service. External areas are also the part of an estate a visiting customer or driver sees before anything else.
A modest scheduled service prevents that entirely. A fortnightly or monthly attendance covering sweeping, litter collection, bin bay wash-down where drainage permits, and edge tidying keeps an estate presentable at a fraction of the cost of periodic recovery. Writing it down is what turns it from a good intention into something that actually happens on a stated interval. Naming the interval also gives tenants something concrete to point at when they ask what the shared cost covers.
