Real Estate Thinking
Vacancy
An empty unit doesn't earn zero — it earns negative, because its costs keep running. Vacancy is the silent variable that separates identical properties, and utilization is the lens that prices it.

What this topic is
The share of space or time producing no income while costs continue — physically empty units, plus the economic version: concessions, non-payment, and the ask-vs-achieved gap.
Why it matters
Vacancy charges full freight (lost rent + running costs) and is permanent (empty months never come back). Small utilization differences compound into opposite returns.
Who should learn it
Anyone operating income property — or any business selling perishable capacity: rooms, seats, hours, machine time.
What you will understand
- Empty capacity is negative, not zero
- Economic vacancy > physical vacancy — measure both
- Turnover gaps are the main controllable driver
- Retention at fair rent usually beats vacancy at high rent
Prerequisites
Common misconception
"Vacancy is just months with no rent — you earn zero those months." You earn negative: the mortgage, taxes, insurance, and upkeep run regardless, so an empty month costs the lost rent plus the carrying costs. And the loss is permanent — perishable capacity can't be warehoused and sold later.
