I would suggest renting in Wasilla. Find a little place and hunker down for the winter until you get a feel for the land, the weather extremes, economics, and meet some locals. Check out what is available by asking around, driving and visiting the areas of interest BEFORE you buy anything online without seeing it, What if you buy on a flood area or off road that needs serious plowing, etc. If you want to live off the grid, it can be done. However, you are going to want a well and a good septic system.
Come ready for the season. Summers are wonderful, but short. Winters are long....but have their own special beauty. There is work. A person has to be willing to just work when they get here with whatever comes their way.
If this has been a dream for you both, just do it. Just sell your stuff, and go for it. Drive the beautiful Al-Can and enjoy the road trip. Just do it.
Palmer-Wasilla area has great soil for gardening. I am not sure what you are interested in, but you stated 200 acres. It is here, but deciding where you want to buy with a look into the near future, well, you need to be here so you don't waster your money.

Are you positive you are getting it at the right price? Can you handle getting financing? You still going to do an inspection even though its as is?
If you really feel you dont need one then dont use one. But the seller is paying the commission regardless and knowing you got the home at the right price and having a smooth transaction is not a bad thing.
