A former school building near Michigan’s K.I. Sawyer Air Force Base has seen a significant increase in value following extensive renovations. Originally sold for just $40,000 in 2011, the 39,000-square-foot property is now listed for $450,000. The transformation includes the conversion of one wing into five separate homes. The 19.38-acre property still retains features of its former life, such as classrooms and a gymnasium, alongside garages and areas primed for further development. This unusual listing presents a unique opportunity for potential buyers interested in a blend of residential and commercial space. The substantial price leap reflects the investment and creative redesign of the once-abandoned schoolhouse.
