of course "it depends." One can certainly build here for around $160 sf (I include dirt work in my costs, but not land). The upper end can push $1,000 sf, but that's "rock star" spending.
I'm currently building a 5,200 sf custom that will come in around $363 sf. The one I built before this, same size, came in at $236 sf.
Land costs here are stout relative to the local economy. A 1 acre lot in a decent subdivision starts around $250K and goes north rapidly.
