Experience lakeside living at its best in this beautifully updated ranch tucked along the shores of Lost Lake. This inviting home features 1 bedroom with flexible living space, 1 full bath, and a bright, open layout that seamlessly connects the kitchen and living area. The true showstopper is the expansive deck perched directly over the water, creating the perfect setting for entertaining, unwinding, or simply soaking in the views. Thoughtful updates completed within the last year include new siding, windows, roof, and interior improvements. A deeded off-road parking space with stairway access provides a private entrance to this unique waterfront retreat. Spend your mornings casting a line right from your backyard, hop on the boat for an afternoon cruise around the lake, or end the day watching sunset from your own deck. Whether you're looking for a weekend escape or a year round home, this is the kind of place where every day feels like a vacation.

This is a rare opportunity for investors and contractors to unlock the full potential of a charming lakeside ranch with breathtaking water views. Tie up your boat and step off your deck right onto your private dock for summer fun. A newly built staircase provides convenient access from the road to the water, and a beautifully crafted retaining wall enhances both the function and curb appeal. The property includes a fairly new tight tank and one designated parking spot. As part of the vibrant Lost Lake community, you’ll have the option to join the Mountain Lakes Club and enjoy access to Baby Beach and other amenities. Inside, you'll find two bedrooms (1 legal), a full bathroom, a cozy living area, and an eat-in kitchen. The home does need work, making it ideal for those looking to renovate or rebuild. Buyers are responsible for their own due diligence regarding renovation or expansion possibilities. SOLD AS IS— Bring your vision and make this lakeside retreat your next great investment.
