I've noticed that San Mateo County only has 1 house listed as sold in the last month. Is this right?I figure this must be a bug considering 13 houses are marked as sold on May 20th and a bunch more on May 19th. I doubt the expiration of the tax credit could have had that much of an effect...right?June 22 2010 - San Mateo00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
