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 decision this helps you make: How to underwrite, measure, and manage vacancy — and when to trade rate for retention to protect utilization.

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.
