We're taking a break from a great discussion on renting vs. buying today to highlight the latest Case Shiller data.
The median price of existing homes in the metro Portland area fell 5.8% year over year in June 2008 according to
Case Shiller, continuing the trend that began in July 2007. This is down 6.2% from the peak in July 2007.
The slight month over month gains we saw in April and May have now reversed, and the price index is down 0.3% from May.
The chart above clearly shows that 1. there was a bubble in Portland, and 2. it is now deflating. The chart and also shows a bit of a plateau over the winter as sales slowed and seller's held out that prices would rebound in the spring.
We've also seen the rate of decline slow a bit as peak buying season is in effect, but look for the decline to accelerate later in the year.
I predict we'll be down at least 10% year over year by the end of December. Any other predictions?

The chart above shows the price index over the past few years. You can see a slight increase in the median price the past two months which corresponds with the seasonality seen in previous years.

The above chart shows Portland, Seattle, the San Francisco bay area (the other areas I consider as closest to Portland) as well as the 20-city composite index. Portland and Seattle are tracking each other nicely, still about a year behind the rest of the market. The San Francisco area has really fallen off the cliff and continues to plummet.

The above chart shows the price index over the past 8 years. Prices have now fallen back to the May 2006 level, but look to have stabilized through the summer buying season.

I've added one more chart, which shows the price changes for the past 20 years. We saw one previous bubble around 1990, and then the more recent bubble. Prices have not been negative in Portland since they started tracking the market until just recently.
ABOUT CASE SHILLER:
The
Case Shiller data focuses on the change in price of existing homes, and tries to exclude the effects of remodeling, or major damage. It tries to exclude investment properties and foreclosures (which would make the data look worse) as well as transfers between family members. It's a much better indicator of how the price of the average or typical house has changed from year to year. For full details on their methodology see their factsheet.
