The Greater Lehigh Valley Realtors (GLVR) has reported that October data reveals an anticipated seasonal slowdown following a stretch of year-over-year climbs in sales numbers tallied this past summer.

Closed sales decreased 0.3 percent to 660 in October, compared to 662 in October 2014.

Pending sales, however, increased 19.2 percent over last year to 696. Days on the market increased 2.9 percent to 70. There is a six-months supply of inventory, a decrease of 38.1 percent, encouraging news for sellers. This time last year it was 9.7 months. New listings are down 17.8 percent to 882.

“Transitory periods in the market are common this time of year,” according to Greater Lehigh Valley Realtors President Chris Raad. “This seasonal drop-off is typical and should not be viewed with any alarm, particularly after the robust numbers tallied this past summer.”

Prices nudged higher as the average sales price bumped up 4.8 percent to $199,641. The median sales price stayed relatively the same, registering a .3 percent increase to $170,500. The percentage of list price received increased slightly as well to 96.2 percent. The affordability index rose 4.7 percent to 200.

“The closed sales numbers for the month might be slightly down versus a year ago, but there are still many nuggets of optimism to mine from the other monthly figures,” said Greater Lehigh Valley Realtors CEO Justin Porembo. “In addition, jobless claims have been at low levels and the Federal Reserve did not raise interest rates. There’s plenty to be positive about in the market right now.”

Sales for year-to-date 2015 are up 13.4 percent to 6,729, compared to 5,468 year-to-date 2014.

September was the first month in three months that closed sales did not increase in double digits.
