Nationally, Existing-home sales rose sharply in December, when sales increased for the fifth time in the past six months, according to the National Association of REALTORS®.
1Existing-home sales, which include single-family, townhomes, condominiums and co-ops, are based on transaction closings. This differs 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 generally account for 85 to 90 percent of total home sales, are based on a much larger sample – more than 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.
2The only valid comparisons for median prices are with the same period a year earlier due to the 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.
3Distressed sales, first-time buyers, investors, all-cash transactions and data for contract cancellations, etc., are from a survey for the REALTORS® Confidence Index, scheduled to be posted February 7.
4Total 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, condos were measured quarterly while single-family sales accounted for more than 90 percent of transactions).
5Because there is a concentration of condos in high-cost metro areas, the national median condo price generally is higher than the median single-family price. In a given market area, condos typically cost less than single-family homes.
