Vacancy Rate: Definition & Example

What Is a Vacancy Rate?
Vacancy rate is the percentage of rental units in a property or market that are empty and available at a given time, or the share of potential rent lost to vacancy.
What does vacancy rate mean?
Physical vacancy rate is vacant units divided by total units. Economic vacancy rate is rent lost to vacancy, and sometimes to concessions and bad debt, divided by total potential rent.
Investors and lenders include a vacancy assumption, often 5% to 8%, when projecting a property’s income. A market with low vacancy usually supports rising rents. A high vacancy rate signals weak demand or too much new supply.
Vacancy rate is the mirror image of occupancy rate: a building that is 94% occupied has a 6% vacancy rate.
Vacancy rate example
A 50-unit building has 3 empty units. Its physical vacancy rate is 3 ÷ 50 = 6%. If those units average $1,200 per month and have been empty for the full month, the property lost $3,600 of its $60,000 potential monthly rent, also 6% economic vacancy.
