Tucked beneath beautiful mature trees, this cozy home offers a surprisingly spacious outdoor setting that is ideal for relaxing, gardening, entertaining, or simply enjoying the privacy and character that comes with a well-established yard. The partially fenced backyard includes a detached shed that provides excellent storage and could make a great workshop or hobby space. Inside, wood laminate flooring flows throughout the home. The updated kitchen features newer white cabinetry and includes all appliances, opening directly to the comfortable family room with an electric fireplace. The primary bedroom is conveniently located just off the family room and also features wood laminate flooring. The refreshed 3/4 bath includes the washer and dryer, which remain with the home. Recent major updates include a NEW ROOF and NEW AC (not furnace), providing valuable peace of mind for the next owner. For buyers seeking affordability without giving up yard space or location, this property is a rare find. Investors take note: the home also offers excellent investment potential, with verifiable rental data available to help evaluate its income-producing possibilities. Whether you're looking for an affordable home in a convenient location, a low-maintenance property with a large yard, or an investment opportunity, this charming O'Fallon cottage is worth a closer look. Conveniently located near downtown O'Fallon, shopping, dining, parks, and everyday amenities-this is small-home living with a big-yard feel and plenty of potential.
