Construction Cost of residential house in Anchorage, AK

[Hui Li]

Any owner builder/developer/GC share your knowledge on the Construction Cost of a new residential house in Anchorage area? assuming a 2000sf, low-end rental duplex.

Exclude land cost, I thought the cost for a low-end single family house is about $100-$120/sf. But a designer corrected me yesterday it minimum cost $200/sf for a low-end, and $250 on average, may up to $325 for high-end. I am speechless now.
