Oahu’s housing market kept its forward momentum going in September with higher median prices and sales volume compared with the same month last year.

According to data released today by the Honolulu Board of Realtors, the median sale price for previously owned single-family homes edged up 1 percent to $760,000 last month from $750,000 a year earlier. And the median condo price jumped 11 percent to $425,000 from $383,250.

The condo median price tied a record set in July.

“The median sales price for condominiums in September is once again the highest we’ve seen in less than a year,” Sue Ann Lee, president of the trade association, said in a statement.

The median price is a point at which half the sales were for more and half for less.

As for sales volume, there were 526 condo transactions last month, up 3 percent from 512 a year earlier. The number of single-family home sales rose 14 percent to 374 from 329 in the same period.
