I think that those people who are really actually looking for a home understand the points being made here. It is one thing to be viewing statistics all the time and humming along as you post. It is another thing to be a buyer out there submitting offers and getting rammed by multiple bids, short sales with offers in and not accepting any other offers, and just a very poor inventory selection right now.
It is a simple statement of fact, nothing more, nothing less. I cannot even say what the median prices, or the sales volume will look like this month compared to last year. However I can say with absolute certainty that so far this spring has a different activity level compared to last for houses in the say 600k and lower price range. As much power as buyers have right now, if you are a buyer and hoping to get something this spring prepare to be frustrated due to these factors and an extraordinary poor inventory selection.
Quick edit, on the 600k and less number please understand that scales with the neighborhood. Obviously 600k in Mira Mesa is NOT moving but 600k in other areas is moving. So apply the statement priced well relative to the local submarket instead of using a raw number. When you get to the higher end though, things are definitely hurting.
