Just closed on a house up there. I bought in South Anchorage, the bottom line on prices is; newer homes are around $200-220 per sq ft, older homes go for around $180-200 per sq ft. I looked up in Eagle River and Chugiac and it is true you get for your money up there. However, I was looking in Jan-Feb and never saw the sun in Eagle River because the town is behind the mountains. I think that would get old in the winter. Also watch out for the traffic. The only way to get from Eagle River to the airport is to drive right through downtown. The traffic gets backed up pretty bad, several times it has taken me up to 30 min waiting at lights.
I'm sure there are some nice Townhomes in the area, but I did not notice any during my search. Nor did I notice any downtown.
