909 Madison Street, Saint Charles, MO 63301 - Saint Charles County

This versatile property is currently configured as an up-and-down duplex, yet it offers an excellent opportunity for a buyer looking to convert it back into a spacious single-family home. The house is currently being used as a duplex with the lower level tenant paying $1,000 a month and the garage is separately rented for $100 a month. The upstairs unit is vacant and can be shown. Each level includes a large living area with its own kitchen and full bath, and an existing interior doorway already connects the two units. Opening the home back up is as simple as removing some surface shelving. With updates, repairs, and a light conversion, this property could easily become a 1,734 sq ft single-family residence featuring three generous bedrooms, two full baths, and a one-car detached garage. The upstairs bathroom layout may require some creative reimagining, but the potential is undeniable. Zoned HVAC is already in place—a major plus. Please note: the downstairs unit is leased through October 2026, making this a great opportunity for buyers who want income while planning their renovation, or investors seeking flexibility. This is a solid location for a duplex and an even better location for a single-family home—especially at this price. Come explore the possibilities and envision your next project!
