Lovingly maintained by the same owners for the past 33 years, this one of a kind 4 bedroom, 2 bath home offers a rare opportunity to own a property that has been thoughtfully and meticulously cared for, as well as updated over the decades. Situated on nearly an acre in unincorporated Algonquin, just a half mile from the marina and minutes from downtown Algonquin, this property offers a unique blend of privacy, recreation, and convenience. Enjoy access to the water, river rights, a shared boat dock, beachfront access, and your own private spring fed pond complete with a waterfall and aerator, with the Fox River providing direct access to the Chain O'Lakes. Whether you're an avid boater, nature lover, or simply looking for a peaceful retreat, this property offers a lifestyle that's hard to find. Inside, you'll find hardwood flooring, abundant natural light, and a thoughtfully designed floor plan. Two generously sized secondary bedrooms and a full bath are located in the original portion of the home, while an extensive addition created an entirely separate private wing highlighted by a stunning hallway lined with floor to ceiling windows. The addition includes a spacious primary suite with a walk-in closet and remodeled bath, a spacious laundry room, and a versatile sitting room that could easily serve as a fourth bedroom, home office, nursery, or den. The updated kitchen showcases quartz countertops, updated cabinetry, and newer stainless steel appliances, while the spacious living room features vaulted ceilings, recessed lighting, a beautiful fireplace, and gorgeous sunrise views through the oversized picture window overlooking the pond. Pride of ownership is evident throughout. Major improvements include a complete tear off roof and gutters, newer Lennox furnaces, Trane A/C units, updated windows, newer well pressure tank, washer, retaining wall, and much more. The heated 2.5 car garage was also part of the addition and offers exceptional storage, along with a massive pull down attic space above with incredible potential for future finished living space. Outside, you'll find mature landscaping, underground drainage, pond fed sprinkler capabilities, and a huge shed with second story storage space. Wake up each morning feeling like you're on vacation all year long. Spend your days boating on the Fox River and Chain O'Lakes, your evenings gathered around the fire pit with family and friends, and your quiet moments enjoying coffee overlooking the water as turtles, ducks, and bullfrogs bring the pond to life and deer wander through the yard. Surrounded by mature trees, peaceful water features, and lush landscaping, the backyard feels like something out of a storybook. Located in an unincorporated area allowing boats, RVs, golf carts, and 4 wheelers, you'll enjoy the freedom to live the way you want while still being close to parks, Metra, restaurants, shopping, and everything the Fox River area has to offer. Properties like this rarely come to market, and after 33 years of ownership, it's easy to understand why.
