TURNKEY WATERFRONT AIRBNB COMPOUND — 3 UNITS ON GRASS LAKE, CHAIN O'LAKES — RC RECREATIONAL COMMERCIAL ZONING — $749,900
The Lake-Heim is a fully operational, income-producing waterfront short-term-rental compound on Grass Lake, part of the Fox Chain O'Lakes — roughly 1.1 acres with about 131 feet of private walk-in sand-beach frontage, a private pier, covered gazebo, and paver patio with firepit. Three furnished rental units (one 2BR + two 1BR, sleeping 12 total) operate under the established "Lake-Heim" brand with live booking calendars, two Airbnb Guest Favorite badges, and seller-provided 2025 Airbnb statements showing approximately $60,423 gross — up about 25% year over year across roughly 393 booked nights. And unlike the typical lake house running rentals, this property sits in Lake County's RC Recreational Commercial district — the county's resort zoning, where lodging, cabins and lake-commercial uses are the district's intended purpose.
WHY THIS PROPERTY WORKS
This is not just a rental property and not just a lake house — it is documented income, irreplaceable sand-beach waterfront, and resort-district zoning in one asset. Lake County prohibits short-term rentals in its residential zoning districts; RC is not a residential district — it is the county's Recreational Commercial classification, "primarily intended to accommodate commercial activities that are dependent upon locations near recreational resources, such as lakes," where hotels/motels and cabins/cottages are permitted uses (buyer to verify permitting status of the existing operation with Lake County). 2025 ran at only ~36% occupancy, so the growth lever is obvious: push occupancy, pricing and distribution toward levels typical of premier Chain frontage and the value-add projection reaches ~$45,892 NOI — roughly a 6.1% cap at asking. Meanwhile the land, beach and frontage hold value no operating metric captures.
THE NUMBERS
$749,900 asking. 2025 effective gross income $60,423 (+25% YoY). In-place NOI $27,726 — 3.7% cap, 12.4x gross rent multiple, $249,967/unit, $5,724 per frontage foot. Value-add projection at ~55% occupancy: ~$45,892 NOI, ~6.1% cap. All figures seller-provided or estimated; projections illustrative; buyer to verify in due diligence.
SIX WAYS TO OWN IT
Continue and optimize the turnkey operation. Owner-operator / house-hack — occupy the premium 2BR, let the two remaining units offset ownership cost. Multi-generational family compound with selective rental income. Add a fourth unit — rebuild on the site of a former legal, conforming fourth cottage; cabins and cottages are a permitted use in the RC district, subject to the code's lot-area and size standards (buyer to verify and obtain county approvals). Convert the bonus flex space (former laundry + full bath) into added rentable space. 1031 exchange — a documented-income waterfront replacement asset.
THE UNITS
Unit 1 — Premium 2BR/1BA: vaulted great room, double sliders to a private lakefront deck, cherry shaker kitchen, quartz island. Airbnb Guest Favorite, 4.91 stars. Unit 2 — attached 1BR/1BA: full kitchen, generous living area, walk-in storage. Unit 3 — freestanding 1BR/1BA cottage: the operation's top earner and most-booked unit. Airbnb Guest Favorite, 4.84 stars. All three fully furnished and actively booked — a buyer continues operations from day one.
LOCATION
Direct frontage on Grass Lake, the gateway lake of the Fox Chain O'Lakes — thousands of acres of connected water roughly 50-60 miles northwest of Chicago, minutes by boat to Blarney Island and near Chain O'Lakes State Park. Strong seasonal recreation demand from the Chicago suburbs, northern Illinois and southern Wisconsin.
