3. Oceanfront Kukio Property
5 bedrooms • 7 full and 2 half bathrooms • 12,620-square-foot interior • 117,046-square-foot lot
This oceanfront Kukio property grabs the No. 3 spot even though it sits in the middle of acres of black lava rock in Kona; the luxury subdivision and golf course that will eventually surround it have yet to be built. It belongs to Carol Ann Bartz, the president and CEO of Internet service company Yahoo! Bartz has a long tech pedigree: When she purchased the property in 2006, she was working as president and CEO of Autodesk, a design software company, and has also worked at Sun Microsystems and Digital Equipment Corp.
