I spoke to a real estate agent recently who said people with homes in the valley are about to get hit with a down turn.  She recommended buying in anchorage because the market is always "fairly stable" meaning even when it drops it doesn't necessarily bottom out.  

Considering the road not being built and the majority of jobs being in anchorage she said that buying out there would be poor investing.  Stick to the Anchorage areas.  Eagle river, Girdwood, & Anchorage are the places you'd want to invest in at this point, if you wanted to invest at all as long as you have a stable job with good security.
