Dataquick vs MLS: why the discrepancies?

In my October 27 blog discussing the Case-Shiller Index, I referred to Bay Area County stats from Dataquick that showed San Francisco’s median prices to be down 12.7% from a year previous (YOY) vs.  the 11.36% that I’d quoted in my October 23 blog.

The reason for the discrepancy?  Dataquick compiles its figures from the San Francisco County Recorder’s Office; my numbers come from the MLS.  Transactions like foreclosures or transfers between family members or between legal entities generally don’t involve agents or brokers so they don’t show up in the MLS.  They also tend to be at lower values because they are often at below market rates, so Dataquick’s numbers will always be somewhat lower than the numbers pulled from the MLS.  Thanks to Rick Campbell at the REReport for his quick response. ...  Additional Details

Update to Halloween Horror: Did it just get scarier….??

The day after I posted my take on the Case-Shiller Index, they came out with July’s report (they’re always trailing three month averages) showing a continuing decline in the San Francisco MSA.  Wait for it:  down 27.3% from July 2007.  Are we worried?  Not that much.  Why not?  Read my October 27 blog:  “San Francisco” means most of the Bay Area when it comes to the Case-Shiller Index.

You want scary?  Median prices are down 45% year over year in Contra Costa County. ...  Additional Details
