The median sale price for a single-family home on Oahu was a record $700,000 during June. That broke the old record of $685,000 back in June 2007. The Honolulu Board of Realtors says the record was also set for condominiums last month at $360,000 - a 9-percent increase over the $330,000 median price last June. The University of Hawaii Economic Research Organization predicts that Oahu's single-family home median sale price this year will rise about 10 percent to roughly $710,000.
