Y’all will get dual BAH. I know you’re recently married, if either one of you have no kids, you will both get BAH at the no dependent rate. There is a BAH calculator online. Check it for you and for your wife. If you live on base, they take the BAH of the higher ranking Soldier and the other Soldier pockets their BAH.

One cool thing about Hawaii is there are many bases there that you can choose to live on. Just because you’re Army doesn’t mean you have to live at Schofield or Wheeler. Up the road there is NCTAMS and it’s very quiet there. Also there are Navy and Airforce bases that you can live on. Shop around. Look up military housing in Hawaii. I forget the website but it has listings at every base on the website. The base housing are mostly run by the same company island wide. If you want to live off base I recommend Mililani or a townhouse in KoOlina. You don’t get much for the money and you will have to pay for electricity and all the other bills you prob wouldn’t have to pay on base.

When I lived there I bought a car and the registration was something like $400 and the renewal price was also something ridiculous like that. Not sure if it’s still that way but I’d keep you car registered where you’re from or where you have your DL from. Call USAA and inquire about car insurance on the island. I’ve had wonderful service with them for many years. They can also help you find cars for sale on the island. Again, good luck!

It's OCONUS so you should be able to stay in lodging until a place becomes available on post. Unless they're at capacity, then you'd have to live off base.

Try to find a house in Mililani, near the Mililani Technical Park, safe and close to base.
Wikau Street, or Palii Street are excellent.
You qualify for USAA insurance.
If your PCS is more than 2 years, get a Hawaii Veteran license plate. Locals don't respect out of state plates.
Online is the best place for a second car.
