The Story of the Farm

Thirty-four years, one family.

Walter and Bente Goldstein bought this land in 1992 — thirty-four years ago. Their youngest child was four. Their oldest was eleven. They wanted a place where the kids had to work.

The two older children dug fence posts and planted the orchards by hand. They cleared brush and rebuilt pasture line. The youngest had his own list of chores from the time he could carry a bucket. Over the years the farm has carried sheep, chickens, family dogs and cats always around the house, eventually a milk cow, a stretch with hogs, and other animals along the way — the kids took care of whatever came with their stretch of the place. None of it was symbolic.

For more than twenty years, the family rented a portion of the back acreage to Walter's Mandaamin Institute for organic seed-breeding research plots — careful trial work that is still in the soil. Bente founded Farmwise here and has run educational programs from the barn and orchard for more than two decades — biodynamic growing, animal husbandry, and how to read a season, taught to children and families on the same land. Hundreds of Airbnb guests and farm-school visitors have come through in the years since.

This isn't a farm someone rented out and stepped away from. A family has lived and worked it every season since 1992.

The children have been out of the house for more than twenty years. In that time, Walter and Bente have kept the place running themselves — the orchard, the gardens, the Airbnb, the Farmwise programming, the research-plot lease — a quieter, more curated chapter of the same farm.

The Goldsteins plan to move back to Norway in 2027. The exact timing is set by IRS primary-residence rules — they need to keep the home as their main residence for a specific window before the sale to preserve the home-sale tax exclusion. They are not in a hurry, but the family would entertain the right offer before then. Before this farm goes onto a public listing, they wanted to put it here first — quietly, for the right person.

Side note · The Airbnb

The Airbnb has been temporarily paused while the property is held as a primary residence ahead of the sale. The listing, the reviews, and the operating history all remain — ready for the next owner to switch back on.

Active Airbnb listing · Elkhorn, Wisconsin
★ 4.94
427 reviews
View live listing on Airbnb →

The brand equity is the real asset. A 4.94-rated, 427-review Airbnb listing is not something a new operator can buy or build quickly — most new hosts take three to five years to reach that level of social proof. With the CUP in place and the listing already on the platform, the next owner can re-open bookings and pick up where the reputation already is.

A Legacy of Teaching

Childhood is a verb.

That is the ethos behind Farmwise, the educational program Bente has run from this property for more than two decades — biodynamic growing, animal husbandry, and how to read a season, taught to children and families on the same land. Visit farmwiseeducation.com →

The family has also rented a portion of the back acreage to Walter's Mandaamin Institute for organic seed-breeding research plots — a quiet but ongoing arrangement that has generated steady rental income from a serious agricultural tenant. The same arrangement is available to the next owner.

The farm-school conditional use permit is what makes this property unusually rare. Any next operator can pick up the educational programming, the homestay rentals, the retreats, or the research-plot lease, without re-applying through the county.

For the Right Buyer

A turnkey foundation
for agritourism, retreat, or working homestead.

Walworth County is one of the most coveted second-home and agritourism corridors in the Midwest. This property is rare in that the permits, the soil, the brand history, and the buildings are already in place — not paper, but lived.

What is already in place

  • Short-Term Rental (Airbnb) Conditional Use PermitActive CUP on file with Walworth County for overnight rental of the residence (classified under the county's "Bed and Breakfast" use). These permits are increasingly difficult to obtain — the work is done.
  • Farm-School Conditional Use PermitSecond active CUP allowing educational, agritourism, and retreat-style programming on the land.
  • C-2 / A-2 Dual Zoning5.7 acres of upland resource-conservation (C-2) and 29.33 acres of agricultural (A-2) — an unusually flexible combination for a property this size.
  • 20+ Years of Organic StewardshipTwo decades managed organically — including Mandaamin Institute research plots on the back acreage. Soil-building, seed-trial heritage, and a story buyers cannot replicate.
  • Two OrchardsEstablished fruit trees in tidy rows, with mature root systems and steady yield.
  • Newly Built Heated YurtA glamping-grade four-season yurt — perfect for Airbnb, retreat lodging, or a writer's studio. Recently constructed.

What that means for an operator

  • Permitted Lodging from Day OneThe CUPs let a new owner host paying overnight guests in the residence (Airbnb-style short-term rental) and program the land (farm-school) without re-applying through the county.
  • A Brand & Network Already BuiltThe Goldstein and Mandaamin Institute name carries 20+ years of credibility in Midwestern organic and seed-trial circles. Educators, growers, and retreat operators recognize the soil and the lineage.
  • Lake Geneva Drive Time: ~10 minutesThree million visitors a year travel to Lake Geneva. This property sits in the catchment with none of the lakefront price.
  • Chicago Drive Time: ~90 minutesWalworth County's #1 feeder market. The Chicago weekend-property buyer is the natural audience for agritourism stays here.
  • Property Tax: $3,128 / yearWisconsin's agricultural use-value assessment keeps carrying cost low — a major operating advantage for a small lodging or retreat business.
  • Multiple Revenue Streams Already ProvenPast use has included Airbnb overnight stays, farm-school programming, seed-trial research, and organic hay and fruit. The infrastructure is here for any combination of them.

The Heart of the Farm

A red barn, a silo,
and a circular drive.

The farmstead sits at the center of the land — a timber-frame red barn with a deep green roof, the original silo standing tall behind it, and a 1900 farmhouse tucked into a ring of mature shade trees.

The circular gravel drive curves through the orchard before opening onto the buildings. The newly built heated yurt, the smaller animal barn, the equipment shed, the dome grain bin — every one of them is still in use.
