Good with caveats
Yes, with one thing to plan around. Septic will likely cost more, because the soil stays wet for long stretches.
What the land says

Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.

Is it legal here?
Zoning
Set town by town. County zoning applies in a town only if the town board has approved it, and some towns zone on their own, so ask the town clerk with the parcel's address.
Building code
Wisconsin's Uniform Dwelling Code is a statewide building code for new one- and two-family homes. The town, village, city, or county enforces it with a building permit and inspections, and in a small town that does neither, the state Department of Safety and Professional Services does, so plan on a permit for a new house almost anywhere.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed with a permit and an approved unit.
Water rights
Owners of land along a creek or lake can make reasonable use of its water.
Drilled to about 180 feet, with pump and pressure tank
