Data & Rent Estimates

Updated November 27, 2024

The Apartment List Research Team aims to make accurate, timely, and transparent housing market data available to the general public. On this page you will find our current data offerings, updated monthly.

Note: In August 2023, we updated the methodology for our vacancy index. If you are working with data dowloaded prior to that date, please use the current series (available below) to access the most recent revisions. The methodology for our rent estimates was not changed.

Available Data Products

Several data products are available using the Download Report drop-down menu below.

1. Apartment List Rent Estimates: monthly estimates of the median rent paid for new leases in a given market. These rent estimates are available at the national, state, metro, county, and city levels back to January 2017. We also provide a summary file which contains the current rent levels as well as month-over-month and year-over-year growth rates for all locations in our sample.
2. Apartment List Rent Growth Rates: derived from our rent estimates, these files contain monthly and annual rent growth rates over time, again at the national, state, metro, county, and city levels.
3. Apartment List Vacancy Index: monthly estimates of the apartment vacancy rate in a given market. As with the rent estimates above, our vacancy index is available at the national, state, metro, county, and city levels back to January 2017.
4. Apartment List Time On Market: monthly estimates of how long it takes newly-listed apartments to get leased. This data is available at the national, state, metro, county, and city levels back to January 2019.

Our data products are updated monthly and include hundreds of locations across the country. The locations that appear in each dataset meet various eligibility criteria and sample size requirements. As our platform grows, so too will the number of locations for which we can publish data.

Methodologies

1. The Apartment List Rent Estimates are tabulated using fully-representative median rent statistics for recent movers taken from the Census Bureau’s American Community Survey, extrapolated forward to the current month using a growth rate calculated from real-time lease transactions that take place on our platform. We use a same-unit, repeat-transaction analysis similar to Case-Shiller’s approach, comparing only units that are available across both time periods to provide an accurate picture of rent growth. Our approach also corrects for the sample bias inherent in private listing sources to produce results that are representative of the entire rental market. For a more thorough explanation, please see our complete Rent Estimate Methodology.
2. The Apartment List Vacancy Index is calculated as the ratio of vacant units to total units among properties that list on our platform. It should be noted that our platform does not provide a fully-representative sample of all apartments in a market, as professionally-managed properties are more likely to participate in marketplaces like Apartment List. For a more thorough explanation, please see our complete Vacancy Index Methodology.
3. The Apartment List Time On Market data compares the "list date" and "lease date" for each transaction that feeds into the Rent Estimate model described above. For more information, please see our report Introducing Our Newest Data Product: Time On Market.
