Home price increases in Honolulu remain the highest in the U.S., according to Homes.com.

Ongoing research by the real estate site found monthly increases in all 100 of the markets it measures, and said that in July, Honolulu’s 13.51 percent year-over-year increase was the highest of the 100 markets.

The next markets in the top five all are in California.

Among midsize markets, Hilo saw  the largest  year-over-year gain in July at 17.43 percent, while Kahului-Wailuku, Maui, was third with a 13.23 percent year-over-year price increase.

The Homes.com local market index is calculated using sales data from the same homes over time, which site officials say more accurately tracks the monthly growth and decline in prices over a longer period of time.
