Pending Home Sales Index declines 0.6% in October

From the NAR: October Pending Home Sales Down Again, but Expected to Level Out

The Pending Home Sales Index, a forward-looking indicator based on contract signings, slipped 0.6 percent to 102.1 in October from an upwardly revised 102.7 in September, and is 1.6 percent below October 2012 when it was 103.8. The index is at the lowest level since December 2012 when it was 101.3; the data reflect contracts but not closings.

[Lawrence Yun, NAR chief economist said:]“The government shutdown in the first half of last month sidelined some potential buyers. In a survey, 17 percent of Realtors® reported delays in October, mostly from waiting for IRS income verification for mortgage approval,” he said.

The PHSI in the Northeast rose 2.8 percent to 85.8 in October, and is 8.1 percent above a year ago. In the Midwest the index increased 1.2 percent to 104.1 in October, and is 3.2 percent higher than October 2012. Pending home sales in the South slipped 0.8 percent to an index of 114.5 in October, and are 1.5 percent below a year ago. The index in the West fell 4.1 percent in October to 93.3, and is 12.1 percent lower than October 2012.
emphasis added

Contract signings usually lead sales by about 45 to 60 days, so this would usually be for closed sales in November and December.
