It's Do able! You'll have have to crunch the numbers.
I'm retired Navy and work at Pearl harbor Naval Ship yard. So i have two checks coming in and a decent income between the two checks . My wife does not work anymore. Due to Arthritis in her knees, cannot remain standing very long periods of time. I cannot afford to own, so i rent.
Most home owners out here Husband and Wife both work full time, to help pay for the Mortgage, or have multi-generational families members, living in the house.
Make sure you keep some of that emergency Fund in case it doesn't work out, just in case!
Mililani area, is a good area to live.The weather is cooler, and gets more rain, due to the higher elevation in central Oahu. You will have the trade wind free air conditioner to keep the temperature down. You should not need Air conditioner for your home. Will help with the Electric bill.
Mililani High school is one of the better city Schools on the island.
Not sure about Middle school, but heard Elementary school is also good.
If you do decide to work. Keep it close to Mililani due to the Horrendous traffic conditions. You have the Above rail systems going in through the Pearl City Aiea along Kam Hwy. Also the H1/H2 Merge Freeway is being widened to add some lanes, along with the rail running into Pearl City. So some lanes are always closed day and night. During the morning and evening traffic rushes, construction stops, for the rushes. But start back up afterwards. This does account for accidents on the H1 or H2 on any given day. Try not to find work beyond Pearl Harbor/Hickham area due to the traffic. I know that's easier said than done but, fair warning
