Appraiser sues band for being blacklisted: A former real estate appraiser for Washington Mutual is suing the bank, claiming she was blacklisted last year for providing a housing market forecast that was too gloomy. In the lawsuit, which was filed a week ago, Wertz says she completed appraisals on two houses in May and then quickly got a call from a WaMu sales manager demanding she change her outlook to "stable" so a loan could be approved.
