Commonly known as the Haagen Haus, this remarkable Civil War-era residence blends timeless elegance, rich history, and exceptional investment potential in the heart of Alton's charming Christian Hill neighborhood. Showcasing over 4,300 square feet of beautifully appointed living space, this fully furnished property features stunning hardwood floors, soaring ceilings, four fireplaces, attractive finishes and fixtures, and views of the iconic Alton Bridge. Currently operating as a successful hospitality-oriented guest house, the property is configured as four separate living units, each with its own kitchen and included appliances, offering incredible flexibility for investors, owner-occupants, or multi-generational living. Generate income by renting all four units, or enjoy the home as your primary residence while leasing one, two, or three additional units to offset ownership costs. The lower-level suite offers a private entrance through a wrought-iron gated courtyard, full lookout windows, a private brick patio, and the perfect setup for an in-law suite, guest quarters, or additional income-producing space. Situated on a prominent corner lot exceeding 9,000 square feet, the outdoor spaces are equally impressive. A private brick-sided courtyard patio with included gazebo provides an inviting setting for entertaining, special events, family gatherings, or peaceful relaxation. Charming brick-lined streets and the character-filled surroundings of Christian Hill further enhance the property's appeal. With an established Airbnb presence, excellent guest reviews, proven rental history, growing tourism demand, low-maintenance management, and furnishings included, this turnkey opportunity is ready for immediate enjoyment and income generation. Whether you're seeking a distinguished historic residence, a thriving hospitality business, or a unique live-and-earn opportunity, the possibilities are truly endless at the Haagen Haus.
