Not a vague $/sq ft. Not a kit price that hides three-quarters of the bill. A real, itemized number — land, well, septic, electric, permits, soft costs and contingency — for the way you'd actually build.
The steel kit you see advertised for $20–$40/sq ft is only about 15–25% of the real cost. The interior build-out, land, well, septic, site prep, and permits are where the money actually goes — and they swing by county more than by state. That's why every page here prices the full build for a real place, shown as low–median–high ranges, never a blind average. Start with how much a barndominium costs or jump straight to your county.
