NOTE: For local information, please contact the local association of Realtors® for data from local multiple listing services. Local MLS data is the most accurate source of sales and price information in specific areas, although there may be differences in reporting methodology.
(1)Existing-home sales, which include single-family, townhomes, condominiums and co-ops, are based on transaction closings from multiple listing services. Changes in sales trends outside of MLSs are not captured in the monthly series. NAR rebenchmarks home sales periodically using other sources to assess overall home sales trends, including sales not reported by MLSs.
Annual Revisions: Each February, NAR Research publishes revisions to existing-home sales, which incorporates a review of seasonal activity factors to fine-tune historic data for the past three years based on the most recent findings. Revisions were made to monthly seasonally-adjusted annual sales rates for 2010 through 2012, as well as the month's supply data. There are no revisions to inventory or price data. Those revisions are posted at: www.realtor.org/topics/existing-home-sales/data.
Existing-home sales differ from the U.S. Census Bureau's series on new single-family home sales, which are based on contracts or the acceptance of a deposit. Because of these differences, it is not uncommon for each series to move in different directions in the same month. In addition, existing-home sales, which account for more than 90 percent of total home sales, are based on a much larger sample -- about 40 percent of multiple listing service data each month -- and typically are not subject to large prior-month revisions.
The annual rate for a particular month represents what the total number of actual sales for a year would be if the relative pace for that month were maintained for 12 consecutive months. Seasonally adjusted annual rates are used in reporting monthly data to factor out seasonal variations in resale activity. For example, home sales volume is normally higher in the summer than in the winter, primarily because of differences in the weather and family buying patterns. However, seasonal factors cannot compensate for abnormal weather patterns.
Single-family data collection began monthly in 1968, while condo data collection began quarterly in 1981; the series were combined in 1999 when monthly collection of condo data began. Prior to this period, single-family homes accounted for more than nine out of 10 purchases. Historic comparisons for total home sales prior to 1999 are based on monthly single-family sales, combined with the corresponding quarterly sales rate for condos.
(2)Total inventory and month's supply data are available back through 1999, while single-family inventory and month's supply are available back to 1982 (prior to 1999, single-family sales accounted for more than 90 percent of transactions and condos were measured only on a quarterly basis).
(3)The median price is where half sold for more and half sold for less; medians are more typical than average prices, which are skewed higher by a relatively small share of upper-end transactions. The only valid comparisons for median prices are with the same period a year earlier due to a seasonality in buying patterns. Month-to-month comparisons do not compensate for seasonal changes, especially for the timing of family buying patterns. Changes in the composition of sales can distort median price data. Year-ago median and mean prices sometimes are revised in an automated process if more data is received than was originally reported.
The national median condo/co-op price often is higher than the median single-family home price because condos are concentrated in higher-cost housing markets. However, in a given area, single-family homes typically sell for more than condos as seen in NAR's quarterly metro area price reports.
(4) Distressed sales (foreclosures and short sales), days on market, first-time buyers, all-cash transactions and investors are from a monthly survey for the NAR's Realtors® Confidence Index, posted at Realtor.org.
The Pending Home Sales Index for January will be released February 27 and existing-home sales for February is scheduled for March 21; release times are 10:00 a.m. ET.
