As this graph shows, March was the best month for sales volume in 4 years.

The supply levels are significantly higher now than in the spring, which is causing the market to balance out a bit more than we witnessed in the winter months. If supply outweighs demand, prices drop.

The sales-listings ratio is actually down from february, which isn't that uncommon, but a big contrast to what happened the same time last year.

Becuase of the large unbalance of demand outweighing demand over the winter months, average prices skyrocketed over those of the past 4 years.

YOu can see the large disparity of available homes for sale over the course of 2009 from the above graph which I believe helped fuel the demand as the signs of economic recovery appeared.
