A tech company CEO paid $15.65 million for a mansion on Paradise Valley’s Mummy Mountain. It’s the priciest home sale ever to close in Arizona.
Steve Sanghi, founder of Chandler-based Microchip Technology, paid cash for the 14,200-square-foot home, according to public real-estate records. Gary Knight, vice chairman of Phoenix-based Knight Transportation, sold the 5-acre estate.
