Why a Building Is Different
A building owner does not manage twenty separate properties but one asset with twenty units. The difference is operational: expenses that belong to no single unit, shared systems whose failure affects everyone, and performance measured at building level.
Four Specifics General Systems Miss
- Shared expenses: lobby electricity, elevator, guard, cleaning, water tank
- Meter readings: actual-consumption billing requires periodic readings linked to unit invoices
- Simultaneous vacancies: five vacant of twenty means 75% occupancy, tracked at building level
- Cyclical system maintenance: elevators, pumps, and central AC need scheduled contracts
The Key Metric: Building Net Income
Building owners need one clear number: what did this building net this year? Reaching it requires summing all unit revenue, subtracting direct and shared expenses, and accounting for vacancy impact. Calculating this manually is exhausting, so it gets skipped.
Allocating Shared Expenses
Three common rules: split equally across units, allocate by area, or charge entirely to the owner. Each gives a different picture of per-unit profitability. What matters is consistency across periods.
Vacancy: The Silent Cost
A vacant unit costs you lost rent and continues carrying its share of shared expenses. A good system shows vacancy cost, not just occupancy rate, and flags units that repeatedly stay vacant longer — usually a pricing or unit-condition signal.
