The uptrend in existing-home sales continues, with January sales rising for the third consecutive month with a pace that is now above year-ago levels, according to the National Association of REALTORS
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.
