Rare opportunity on Long Lake — one of northeastern Minnesota's most private lakes with zero public boat access. This 3,300+ sq ft slab-on-grade home delivers effortless single-level living on 2.1 wooded acres with 250 feet of pristine shoreline exclusively yours.
Original 1989 build was transformed by a substantial 2018 addition, resulting in a thoughtfully designed 5-bedroom, 3-bath home that lives as well for year-round residency as it does for a lakeside retreat. The new kitchen anchors the home's interior — featuring custom white hickory cabinetry, quartz countertops, and stainless appliances — complemented by separate living and family rooms — generous, flexible space that comfortably accommodates large gatherings without feeling crowded.
A wood-burning fireplace with Accucraft blower system and lifetime-guaranteed stainless chimney liner anchors the living space — built for serious Northwoods winters — with lake views from many living spaces inside the home. Step outside to multiple patios designed for outdoor living at every hour of the day. Direct water access via your own private boat launch means no trailering to a public ramp — just get in and go. Two detached garages with 6 total stalls handle everything lake life demands: boats, watercraft, ATVs, snowmobiles, and vehicles alike. One garage also houses a lakeside sauna retreat!
Long Lake spans 209 acres, reaches 51 feet at its deepest, and supports exceptional fishing — Walleye, Northern Pike, Largemouth Bass, Crappie, and Bluegill. With fewer than 120 properties on the entire shoreline and no public access, the water here stays quiet. That's increasingly rare and impossible to replicate. There is an optional lake association for owners to join as they please, they stock the lake and have annual gatherings.
Located 7 miles east of Cotton off County Road 52. Duluth approx. 45 minutes. Twin Cities approx. 3.5 hours.
