If you go, don't rent furniture. That's like flushing money down the toilet. Gradually add stuff purchased at garage sales, thrift shops, Salvation Army stores, and from discount department stores. Start out with some blankets or a sleeping bag on the floor if you have to, and just add stuff as you go, but do pick up a few cheap lamps to start with, so you can see at night. Get a folding table or other cheap table and folding chairs at Walmart or one of the other places mentioned. Throw a cheap table clothe over it. There's your kitchen table! You can temporarily use it as your office table, too, until you can get another cheap table or desk for that. Just keep going that way, and you will do okay.
During a homeless spell some years ago, I was able to camp out for about 3 months in a relatives decrepit fixer-upper investment property. I used a sleeping bag and blankets on the floor, a folding table loaned by another relative, a tabletop cube fridge with a tiny freezer compartment loaned by that same relative, a folding chair loaned by another relative. I paied $7 at the Salvation Army store for a used microwave that I still have. I bought a few utensils at the Salvation Army store and also paid $7 dollars at the same store for a handicapped potty--there was no toilet in the bathroom at the fixer upper as it had been broken, so it was removed. The toilet drain hole was still there, so I could dump the stuff down there. Not nice, but I had a roof over my head, and pets, too. Mice and bugs. I picked up some cheap plastic ware to hold/heat/eat food from. I had an industrial fan of my own to use on hot days, and all my personal possessions crammed into my Jeep Cherokee. Hey why pay to rent storage space when the car can hold it for nothing?
Fortunately, my circumstances have improved some since then. I now live in an old trailer that I rent from my father and step mom, so I have a roof of my own over my head.
You seem more interested in the Hawaii job than in the other one. If this is a firm job offer, then you might as well go for it. However, don't move there until they confirm, preferably in writing, that you have the job. To be on the safe side, make sure you have enough money for a return ticket, before you go. It would be terrible to get there only to find out that you don't have the job, and no income to pay for a roof over your head.
Anyway, good luck!
