    What's special

    Three above-ground floors
    Historic 1906 Schoolhouse | 10,000 Sq. Ft. Mansion | Fully Furnished | 5 Minutes from Port Austin Welcome to the Grindstone City Schoolhouse, a truly one-of-a-kind historic property located just five minutes from Port Austin at the tip of Michigan’s Thumb. With approximately 10,000 square feet of finished space, this extraordinary property combines historic character, impressive scale, and proven hospitality potential in a setting that makes it unlike anything else on the market. Originally built in 1906, the building served as a schoolhouse until the 1950s. It then sat vacant for decades before a dedicated craftsman spent approximately 15 years completely remodeling and transforming the property, bringing this remarkable piece of history back to life. The home features three above-ground floors, with approximately 2,500 square feet per floor, and soaring 13-foot ceilings that give the interior an incredible sense of space and grandeur. There are 5 bedrooms, 6½ bathrooms, and 2 kitchens, along with an abundance of flexible living, entertaining, and gathering space. The property is being offered fully furnished, making it an exceptional turnkey opportunity for a buyer looking for a unique residence, vacation retreat, investment property, or hospitality venture. The Grindstone City Schoolhouse also has a proven history as a destination property. It operated as a successful bed-and-breakfast from the late 1990s through approximately 2010. In 2012, the current owners purchased the property and converted it into their family’s permanent home, where they raised their family and made it their own. Since 2022, the property has once again welcomed visitors as a successful Airbnb. Its location makes it especially appealing to those who appreciate the beauty and recreation of Michigan’s Thumb. Just minutes from Port Austin, the property is close to the area’s beaches, Lake Huron, boating, kayaking, hiking, dining, and the many attractions that draw visitors to this unique part of Michigan. Whether you envision it as an extraordinary private residence, a family compound, a vacation getaway, a bed-and-breakfast, or a continuation of its successful short-term-rental history, the possibilities are remarkable. Offered at $449,999 and sold fully furnished. New roof in 2019, windows in 2012 and septic in 2022. The Grindstone City Schoolhouse isn’t simply a home — it’s a piece of Michigan history, a remarkable architectural transformation, and a property with more than a century of stories waiting for its next chapter.
    What the owner loves about this home
    What I love most about this home is that it is truly unlike anything else. It has the character and history of a 1906 schoolhouse, but the space and comfort of an enormous family home. The 13-foot ceilings, incredible scale, and unique layout give every room a feeling you simply can’t find in a typical house. There is so much room for family, friends, entertaining, hobbies, and making memories. Our family lived here for many years, and this house became much more than a property to us — it was home. We raised our family here, celebrated holidays, welcomed friends, and created countless memories within these walls. I also love the location. Being just five minutes from Port Austin, you get the peaceful, unique feeling of being at the tip of Michigan’s Thumb while still being close to Lake Huron, beaches, restaurants, boating, kayaking, hiking, and everything Port Austin has to offer. The history is another thing that makes this place special. Knowing that children walked these halls beginning in 1906, that the building sat vacant for decades, and that someone devoted 15 years to bringing it back to life gives the property a story and character that can’t be recreated. It’s a very special place, and while it’s time for our family to move on, we’re excited to see someone else enjoy it and create their own memories here.
