Thanks to ultra-low mortgage rates, it's an excellent time to buy or sell a home across the U.S. But what about in Hawaii?

Is the state's housing market too pricey for buyers? Not-so-great if you've got a home you want to sell? Or just right — for everybody?

Home values provide some answers. They indicate that the market in Hawaii is cooling off, according to Zillow, though you might find vast differences from one city or one corner of the state to the next.

Current home values in Hawaii

Home values have been flat throughout Hawaii and are up 0.05% from a year ago.

Statewide, the median value for a single-family home — meaning half are worth more, half are worth less — is currently $616,600 , Zillow says.

Could you afford that? Let's say you want to buy that mid-priced home using a 30-year fixed-rate mortgage at this week's average interest rate, which is a low 3.69%, says mortgage company Freddie Mac.

With the 30-year mortgage rate at 3.69% and the median home value for Hawaii at $616,600 , a representative monthly mortgage payment would be $2,834.62.

How the Hawaii housing market stacks up

Property values in Hawaii are high by historical standards and are higher than what the typical house is worth nationwide.

The median home value throughout the U.S. is $229,600, which is up 4.88% from a year ago.

Zillow predicts U.S. home values will rise 2.2% over the next year, while in Hawaii, they're expected to rise 6.20%.

Homes are going on the market in Hawaii at a median price of 501 per square foot, versus 155 per square foot nationwide.
