"State and county officials are warning consumers of a widespread scam -- an official-looking mailing offering to reduce 2010 property tax bills for $189. Judith Kent of Tigard opened one such mailing on Saturday from "Property Tax Adjusters" of Granada Hills, Calif. The missive -- which listed her address, property values and an "Assessor's ID No," -- said a reassessment could mean an annual tax savings of $2,400. It also promised a refund of an $189 service fee if she failed to qualify." http://www.oregonlive.com/business/index.ssf/2010/03/beware_of_property_tax_adjustm.html http://media.oregonlive.com/business_impact/other/38 AM-page-1.pdf I don't know other appraisers experience, but when someone calls me and says they think they are over-assessed (RMV), I tell them to call the assessor first and ask what reduction would be necessary to save the first dime in actual property taxes. They never call me back.
