WHY??? It's HAWAII! Give me ten reasons, cost aside why SoCal is better than Hawaii. And I'm not trying to be rude, I'm serious!
Weather #1, isolation#2.
Of the dozen or so couples that have moved there over the years none of them lasted over 2 years before they moved back to So. Calif., they coudn't stand it.
Even a Japanese contractor that I know that was left a large amount of acerage there by his mother goes over and builds one house for sale every year and comes back to his home in So. Cal.
