Administration is the hidden cost of self-management
Schemes self-manage to avoid an agent's fee, and for a small building that is often a sensible decision. What it does not remove is the work, which simply moves to whichever owner is willing. Chasing an insurance certificate, reconciling an invoice against an unclear scope, or fielding a neighbour's complaint about a shared area all take time from somebody who is running their own business.
A service arrangement can either add to that or reduce it. One that generates queries, variable invoices and periodic requests for documents will quietly become a burden. One with a fixed scope, predictable billing and documents supplied without being asked for takes almost nothing. The difference is invisible on price and considerable in practice for the person carrying it. For an unpaid volunteer, that difference is often what determines how long they continue.
