Back with a full market wrap
It's been three months since my last post. Way too long, but family and work deadlines come first.
According to the more complete Warren Group numbers, SFH prices are down 4.4% from last September, and a cumulative 13.1% since September 2005.Looking more closely at the MAR numbers, sales for both SFHs and condos plummeted in September:
Condo sales in September were the weakest since 2002, while SFH sales were the weakest since 1992 according to the MAR press release (PDF).
MAR continues to report that median prices are holding up fairly well:
Note that while median condo prices remain above past year levels, median SFH prices reported by MAR are down 5.5% from 2005 levels, and are below 2004 levels.
The one tentative sign of improving market conditions over the past year has been the better balance between for sale inventories and monthly sales (i.e., Months Inventory). The plummeting sales in September returned this figure to 12.1 months, close to last year's level.

Frankly I'm surprised MAR has been so restrained about the new record high median condo price reached in June. Perhaps even they recognize that the relatively strong sales in the pricey downtown Boston condo market (see story
The reason I want to emphasize this plot is that the differences between the two reports are now spanning at least a two year period, so the trend is beginning to amplify. For instance MAR reported 2007 prices down 1.6% relative to 2006, and 2006 down 1.1% from 2005 (pretty much the market peak). That means MAR numbers indicate that the statewide SFH median price has fallen a cumulative 2.7% from summer 2005.
Reading the media and blog coverage of these data releases, I couldn't help but notice a growing move toward balancing MAR numbers with those from the Warren Group and others. Below, I've plotted the YOY change in SFH prices over the last 15 months from both MAR and the Warren Group. For comparison, I've also plotted the S&P Case-Schiller HPI for the Boston MSA, which differs from the others in that it reports prices from repeat transactions, in a smaller geographical area.

One thing that I have been noticing is that MAR is continually revising their stats from past months/years. I don't have the time to keep up with their changes, and they don't bother to report the changes when they make them, so I will have to acknowledge that the numbers I'm plotting are "as originally reported." The differences are typically small, so not too big of a deal I guess. Doesn't do much for my confidence. I plan to spend more time from now on using the S&P/Case-Shiller® Home Price Indices, which have a number of advantages (see previous post
December/January were unusually warm, and mortgage rates dropped, likely contributing to unusual seasonal strength in Jan/Feb closings. In Feb the weather turned and rates rose, and I expect the March closings and months inventory will suffer by comparison to last March (which was relatively strong).
