                     With the release of its September 2022 housing trends report,
                     Realtor.com® incorporated a new and improved methodology for
                     capturing and reporting housing inventory trends and metrics. The new
                     methodology updates and improves the calculation of time on market and
                     improves handling of duplicate listings. Most areas across the country
                     will see minor changes with a smaller handful of areas seeing larger
                     updates. As a result of these changes, the data released since October
                     2022 will not be directly comparable with previous data releases
                     (files downloaded before October 2022) and Realtor.com® economics
                     blog posts. However, future data releases, including historical data,
                     will consistently apply the new methodology. More details are
                     available at the source's Real Estate Data Library
                     (https://www.realtor.com/research/data/).
                     
                     With the release of its November 2021 housing trends report,
                     Realtor.com® incorporated a new and improved methodology for
                     capturing and reporting housing inventory trends and metrics. The new
                     methodology uses the latest and most accurate data mapping of listing
                     statuses to yield a cleaner and more consistent measurement of active
                     listings at both the national and local level. The methodology has
                     also been adjusted to better account for missing data in some fields
                     including square footage. Most areas across the country will see minor
                     changes with a smaller handful of areas seeing larger updates. As a
                     result of these changes, the data released since December 2021 will
                     not be directly comparable with previous data releases (files
                     downloaded before December 2021) and Realtor.com® economics blog
                     posts. However, future data releases, including historical data, will
                     consistently apply the new methodology. More details are available at
                     the source's Real Estate Data Library
