    Overview

    This side-by-side ranch duplex offers two separate residential units under one roof, with each side currently configured as 3 bedrooms and 2 full bathrooms. Both units include a large lower-level den, which can serve as additional living or work space, or potentially support future bedroom conversion. The property has benefited from meaningful interior updates across both sides, including new flooring, renovated bathrooms, some updated lighting, and select new doors. One unit also has an egress window already in place, supporting the feasibility of a future bedroom layout change. The seller notes potential to convert each side into a 4-bedroom, 2-bath configuration.

    The duplex is located at 517-519 E Holum Street in DeForest, Wisconsin, on a 0.24-acre lot. Current rents are listed at $2,200 and $2,715, providing an income stream immediately after acquisition.

    For buyers and investors, the combination of updated interiors, generous room sizes, and adaptable lower-level space may appeal to tenants seeking more flexible layouts. Owner-occupants may also value the side-by-side configuration and the option to reconfigure a unit toward additional bedrooms over time, subject to applicable requirements.
