Inventory is up 4.7 percent compared to last year, and that's great news for buyers. The available inventory is likely to continue to increase for the next several months, as is consistent with seasonal trends.

We've seen 15%, we've seen 11%, we've seen such high levels of appreciation. The market cannot sustain that.

The numbers show it was a banner year. All indications are that this year will be the same. 2006 started off exactly how 2005 left off.
