Have you been up to AK before? Keep in mind that it is a huge change from what FL has to offer! Finding 10-15 acres with in a couple hours of Anchorage is doable, as long as one has a fair size chunk of money. Would you be looking for 'raw' land on some place that is already built? Some friends of our recently bought 40 acres for $61,000 but they are 80 miles from Anchorage and this was bare ground. They are in the process of putting in a drive way and build pad this year. Some other people that we know recently sold their place, house on 5 acres about 48 miles out of Anchorage for $1,000,000.
Having said that, AK is a good place to live and is slowly becoming more like the lower 48 all of the time. While we would like to have more land, we are at the end of the road with mountains as our back yard.
I am sure that there will be lots of other replies, that will give you more information.
