A 39,000-square-foot former school on the old K.I. Sawyer Air Force Base in Gwinn, Michigan is back on the market for $450,000 after partial residential redevelopment and years of work by its current owner.
A former school building in Gwinn, Michigan is up for sale again, this time listed at $450,000. The property at 530 Mitchell Street sits on the grounds of the old K.I. Sawyer Air Force Base and was bought for $40,000 in 2011. Since then, only part of the building has been converted for residential use. As of now, there is no independent confirmation from local government or county records that the property is officially listed for sale, and recent status changes have not been verified by Marquette County or municipal sources.
The jump in asking price-from $40,000 to $450,000-reflects the challenges of turning a 39,000-square-foot school into housing. Projects like this require significant investment, patience, and a willingness to deal with building codes and infrastructure issues. Anyone interested in buying should check the Michigan Bureau of Construction Codes for current redevelopment and occupancy requirements.
Partial residential conversion
The current owner focused on Wing A, converting it into five residential units. These units are described as having high ceilings, open layouts, and modern kitchens. The largest has two bedrooms and two bathrooms. Other options include a studio and multi-bedroom layouts, all with in-unit laundry. The rest of the building is mostly untouched, with original features like lockers, chalkboards, and institutional flooring still in place. There are no official statements from the Gwinn Area Community Schools board or Marquette County confirming that these units are finished or meet code requirements.
Wings B and C have not been redeveloped. Wing B still contains the original gym, four classrooms, a guest area with a bunk room, and extra studio spaces. Wing C is used for storage, meetings, and garage access. The property covers nearly 20 acres and reportedly includes 36 garage spaces and extensive covered parking-features rarely found in new developments due to zoning rules. However, these numbers have not been independently confirmed by the Marquette County assessor or the local Multiple Listing Service as seen in comparable listings.
Infrastructure and market realities
The current listing by Dylan Willey of Coldwell Banker Schmidt Realtors states that the building is connected to public water, sanitary sewer, natural gas, and electricity. The size and existing infrastructure set it apart from typical residential properties. At $450,000, the price works out to about $12 per square foot, which is well below the cost of new construction. Still, there are no official comments from Marquette County Public Works or local utilities confirming these connections for 530 Mitchell Street.
Finishing the rest of the building will require substantial investment and expertise. Buyers will need to address commercial zoning, possible asbestos removal, and the cost of heating and insuring a structure built in 1960. The property is being sold as a partially completed project, with significant work left before it can be fully occupied or further redeveloped. Local ordinances and zoning rules, available through Marquette County administration, may affect future plans for the site.
What buyers should know
Projects like this are not quick flips. They require careful planning, a solid understanding of local codes, and enough funding to handle unexpected problems. While the price per square foot is low, the total cost to finish the project can be high. Anyone interested should review local regulations and budget for both construction and ongoing expenses. The City of Farmington and other Michigan towns often post redevelopment guidelines and public hearing notices online, which can be useful references for similar projects.
Properties like the former Gwinn school offer space and infrastructure that are hard to find in new builds, but they also come with unique risks and responsibilities. For buyers with the vision and resources to finish the job, the opportunity is real, but so are the challenges. It's a good idea to talk with local officials, such as the Marquette County Board of Commissioners or the Gwinn Area Community Schools board, before moving forward with a purchase of this size.
The K.I. Sawyer Air Force Base was decommissioned in the 1990s, leaving behind several large institutional buildings. In the years since, some have been repurposed for housing or business, while others remain empty. The sale of this partially converted school shows both the potential and the complexity of redeveloping older properties in rural Michigan.
