OP here - Mum has been looking at real estate there for a few months. A bit of backstory we are the extent of our family my Mum, my daughter and myself. No one in Wa but a few gravestones here. My concern in regards to work comes down to medical insurance alot has changed there too. My family is small and broken but good....yeah good.

It is kind of exciting to do something impossible like this once I can get past the raw terror. I guess I am looking for thoughts from folks that may have done a long-distance move and how they did it? And I do agree she needs to look into it a lot more in regards to her possible future.
Thank you to all who have already shared their thoughts/opinions.
I will first say that I agree with all of the previous posters that this plan does not sound well thought out in the slightest. I will also give a brief experience of our two large moves especially the logistics of our lodging.
Both moves involved selling our house at the time and moving to a different state and setting up our lives again. Both of these were done for jobs.
The first was because my job was relocated. My company 100% paid for all of our moving expenses (including full service movers) and my husband was able to keep his job as long as he was wiling to travel. We sold our house before we moved and did a rent back to stay in it until the day we had to leave. We drove with our dog to our new state and stayed in a 2 bedroom apartment with most of our things still in boxes until we were able to close on the house we were building, which of course took much longer than anticipated and our month to month lease was quite expensive as they weren't very common in the area so people charged a premium. Of course when we finally were able to move into our house we had to hire another set of movers on our own to get our things from the apartment to the house.
Our second move was for my husband's job as he was offered his dream job in CA, thankfully my job allowed me to keep my position traveling and doing some remote work. His new company also paid for all of our moving expenses, including the mortgage on our house until it sold (took about 2 months but we didn't put it on the market until we were out of it this time as living in a house that is being shown was NOT for me) and paid for a corporate apartment for us for 6 months and storage for all of our stuff while we were in that corporate apartment. We drove with our dog again to our new state and got an apartment for another 6 months or so (on our own) after our corporate lease was up (we kept our stuff in a storage unit at our new apartment complex this time) and then purchased our house and moved in, which as I am sure you can guess involved more money and movers.
All of this to say that even though we were given every single advantage possible thanks to our companies footing so much of the expenses it was still difficult and expensive. There are so many fees for things that you don't think about, and paperwork and things that come up that you don't anticipate even after doing it once like having to go to Target to buy basic supplies to tide you over in your temporary living situation even though you have all of these things packed away in boxes in the room next you, you just don't know which box it is in, or how you would ever get to that box even if it was flashing neon in the room! Both moves were great opportunities, and I would do them all over again, but not unless we at least each knew that we had good employment at the new destination.
One of the people I went to college with is an animator at Disney (he animates water or at least did the last time I spoke with him) he has a degree in engineering with a concentration in hydrodynamics as far as I can remember. No one goes from working in the parks to being an animator, it is a very specialized skill set with a variety of different degree options to get you there depending on the type of animation that you want to do.
Make sure everyone does their research and knows what they are getting into!
