D.T.
I'm a transplant from Alaska. My parents and younger brother are there. Yes, cost of living is higher, but most pay checks take that into account. Remember it's only more expensive because it's ALL shipped up. I suggest buying in bulk and limiting your shopping as much as you can. My parents shop a month at a time. I also suggest not living directly in Anchorage, look into the communities just outside, like Chugiack and Eagle River. I personally suggest Wasilla and Palmer but they are farther away but growing fast and lovely. Winters are LONG and dark, but they are getting warmer. Summer is long, bright and beautiful. A 4x4 vehicle is a must! 2 would be perfect, one for you and one for him, that way you aren't stranded at home car less. Get out while you can, get sunshine while you can. I suggest taking up a hobby to keep you busy if you're planning on being a SAHM. People up there are friendly but are also very independent and self- reliant. I'm not sure how you feel about guns, but depending on the community you choose, having one might be a good idea. The farther from Anchorage you choose to live the more wilderness it becomes. Bears can happen.
I just had a funny thought, I'm trying to get my parents to move back down here, want to contact them and trade houses? I'm kidding...mostly. :)
Good luck, I hope this helps.
