Many thanks to M for our update:

We closed out the month very strong, 800 sales in the last 2 days.  Again, August set up perfectly for late month closes; the last day was a Friday before a long holiday weekend.  We will be starting September w/ the lowest number of pending sales I can ever recall.
 
Active                       56,007
Under contract             4,525
Sold                           4,292

As agents have several days to update their listings, the official number may be slightly higher than this. 

Two factors may account for the sales number to be as high as it is.  One is as M pointed out- most people prefer to close as close to the end of the month as possible.  The last day of August was a Friday before a three day weekend, making it a popular day to close. The other would be that many loan products are being discontinued, and buyers may have been anxious to close while they can.  Even still, sales are down from July’s 4,330 and are down  around 25% from the 5685 sales recorded in August 2006.  As M also pointed out though, pendings are down for September, so sales don’t look promising going forward.
