Housing markets on Hawaii island and Kauai had a bumpy June but still maintained higher median prices and sales volume through the first half of the year, according to a new report from Hawaii Information Service.

The results in June included more than 30 percent gains for median condominium sale prices on both islands and close to 15 percent declines in condo sale volumes.

The biggest gain last month occurred for Hawaii island’s median condo sale price, which jumped 37 percent to $268,000 from $196,000 in the same month last year.

Most of that gain was driven by condos in North Kona, where there were 29 sales for a median $259,000 last month compared with 39 sales for a median $195,000 a year earlier, representing a 33 percent price gain. There also was a big difference in South Hilo condo sales, where the median roughly doubled to $125,000 in June on six sales from $60,750 on eight sales a year earlier.

For the first half of the year, Hawaii island’s condo median price was up 16 percent to $295,000 from $254,500 in the same period last year.
