Diane has faced controversy for tax avoidance, having paid zero state income tax in four of the five years from 2010 to 2014. An investigation revealed her 8,500-square-foot home was fraudulently assessed as a 1,663-square-foot ranch. After initially denying access to a tax assessor, she eventually provided accurate data, increasing her property’s assessed value from under $500,000 to over $1 million.
