Unit 2 is a remodeled 2-level duplex completed in 2025, featuring four bedrooms, two bathrooms, a sunlit living room, and a modern kitchen with stainless steel appliances.

Improvements include a roof installed in 2018, gas heating conversion and related systems completed in 2010, and replacement windows from 2009. The property sits on a quiet side street in the Prattville neighborhood. BikeScore is 43 (somewhat bikeable), walkScore is 71 (very walkable), and transitScore is 55 (good transit). A large driveway provides for three off-street parking spaces.

The layout supports multiple living and leasing scenarios, whether you plan to occupy one unit and rent the other or operate the property as a residential income asset. With key updates already completed, the home presents a practical, turnkey option for an owner-occupant or investor seeking a manageable path to move-in readiness. Central A/C is noted as an easy addition if desired, providing an upgrade option for comfort planning.
