Vacancy Rate

A vacancy rate is the percentage of rental units in a given area that are currently empty and available to rent.

Vacancy rates give renters a sense of how competitive the local housing market is at any given time. When vacancy rates are low, landlords typically have more bargaining power because there are fewer options for renters to choose from. When vacancy rates are high, renters may have more leverage to negotiate on price or lease terms. The U.S. Census Bureau’s American Community Survey (ACS) tracks vacancy rates across cities and regions and is one of the most widely cited sources for this data.

For example, if a city has 10,000 rental units and 500 of them are currently unoccupied, that city has a 5% vacancy rate. A rate around 5% is generally considered balanced, meaning neither renters nor landlords have a strong advantage. A rate below 3% typically signals a very tight market, where renters may face higher rents and more competition for each available unit.

Vacancy rates can vary significantly by neighborhood, unit size, and price range, so a citywide number may not reflect conditions in a specific area you are searching.

This metric matters to renters because it helps set realistic expectations before beginning a search. If you are moving to a city with a very low vacancy rate, you may want to start your search earlier, prepare your documents in advance, and budget for rents that are likely trending upward.
