Own a piece of Longmont history! The William Butler House, circa 1884, is a stately Victorian that blends historic significance with refined modern living, set within Longmont's original square mile. Featuring a mansard roof, this iconic home sits on a rare third-acre lot backing to Old Mill Park. Privately gated and beautifully landscaped, the grounds showcase mature trees, heirloom plantings, and antique brick walkways. Every room has been thoughtfully updated, including a new kitchen, new bathrooms, upgraded electrical, new roof, and new exterior paint. The custom gourmet kitchen features ZLINE appliances, including an 8-burner dual fuel range, custom cabinetry, and a Shaws of England farmhouse sink. Timeless details such as crown molding, an original fireplace, high ceilings, and wood floors add to the home's character. Additional highlights include an in-law suite in the basement with a separate exterior entrance. Luxury touches include a steam shower, and the home is one of the few Old Town properties with AC. Added bonus: the current owners hold a short-term rental license, offering exceptional income potential. Walk to Main Street shops and restaurants!
