In our case, most items are no big difference or cheaper in Kona than LA. We're should be in Oahu by June 9 or 10, picking up keys on the 11th!
LA housing: Lease = $1800 + Utilities (Electric/Gas/Water/Trash/Cable) $435 min = $2235
Oahu High Rise Condo = $1000 Includes Utilities
$1235 just in housing savings. My average groceries in CA for 2 adults = $125/wk so even if Hawaii is 40% higher in food to bring it $175/wk, an extra increase of $200 per month, I'm still $1,035 ahead.
Already have quotes for car and renter's insurance both more than 30% less.
Each family has to decide what is important to them, what concessions they are willing to make, what income base they will have that's secure (savings/investments), what the job market in their field is in Oahu or whatever island they want to go to.
Each situation is different, make the best decision for you and yours. It's a go...best of luck! There are no guarantees in life, just death and taxes - and they both suck!
Aloha! Ruby
